To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the previous auction prices and the current condition of the coin.

1. Current Condition: The coin has a condition rating of 90 (EF), indicating that it is in quite good shape.

2. Previous Auction Prices:
- In previous auctions, we have seen hammer prices that vary significantly. For example:
- A coin with a condition of 90 was auctioned for 1900 (2011-06-30).
- Another coin with a condition of 90 was auctioned for 1400 (2015-03-09).
- There are also examples of coins with lower conditions that sold for less, but the price range for similar conditions is relevant.

3. Average Hammer Price: The average hammer price for this coin is 1137.51, which gives us an idea of what buyers are willing to pay on average.

4. Starting Price: The starting price is 750, which is reasonable given the auction price history.

5. Estimation: Given that the condition of the coin is good (90) and considering the previous auction prices, a maximum purchase price could be in the range of 1500 to 2000 euros. This is based on the fact that coins in similar conditions have reached hammer prices in that range.

Therefore, an estimated maximum purchase price for this coin could be approximately 1800 euros.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on the provided data:

1. Current Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in relatively good shape. This suggests that its value should be above that of coins with lower conditions.

2. Historical Prices: By looking at previous auction prices for coins with similar conditions, we can see that there is a great deal of variability. For example:
- In 2011, a coin with a condition of 75 was auctioned for 5200 euros.
- In 2012, a coin with a condition of 90 sold for 60000 euros, indicating that coins in better condition can reach significantly higher prices.
- In 2016, a coin with a condition of 75 sold for 6500 euros.

3. Average Auction Price: The average auction price for this coin is 7523.26 euros, which is also an important indicator.

4. Starting Price: The current starting price is 1200 euros, which is quite low compared to previous auction prices.

5. Sales Trends: The coin has been auctioned 25 times, of which 22 have been successful sales. This suggests that there is consistent interest in this coin.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 5000 to 8000 euros, considering that the condition is good and that previous auction prices have been significantly higher.

Therefore, a reasonable estimated maximum purchase price could be between 6000 and 7000 euros.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on the provided data:

1. Current Condition: The coin has a condition rating of 75 (MBC), indicating that it is in an acceptable state, but not of the highest quality.

2. Auction History:
- The average hammer price for this coin in the past is 1421.05 euros.
- It has been auctioned 20 times, of which 14 have sold, indicating good demand.
- Previous hammer prices for coins with a similar condition (75) have varied, but there are examples of auctions reaching up to 625 euros (2012) and 350 euros (2011).

3. Price Trends:
- In previous auctions, hammer prices for coins with a condition of 75 have ranged between 180 and 625 euros.
- The most recent auction with a condition of 85 had an estimated price of 400 euros, suggesting that the value may increase with better condition.

4. Estimation: Given that the condition of the coin is 75, and considering the auction price history, a reasonable maximum purchase price could be in the range of 400 to 600 euros. This is based on the fact that the average hammer price is 1421.05 euros, but since the condition is not optimal, the price should be adjusted downward.

Estimated maximum purchase price: 600 euros.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on the provided data:

1. Current Condition: The coin has a condition rating of 70 (VF-). This indicates that it is in an acceptable state, but not among the best qualities.

2. Auction History:
- The average hammer price for similar coins in the past is 2367.7 euros.
- The average starting price is 805.24 euros.
- The coin has been auctioned 34 times, of which it has sold 24 times, indicating good demand.

3. Previous Prices:
- In previous auctions, hammer prices have varied significantly, ranging from 90 euros to over 27,000 euros, depending on the condition and demand at that time.
- The last auction with a similar condition (70) had a hammer price of 106 euros.

4. Price Trends:
- Hammer prices tend to be higher for coins in better condition. A condition rating of 70 suggests that the hammer price could be below the overall average, but it could still be significant.

5. Estimation:
- Given that the starting price is 250 euros and considering the hammer price history and condition, a reasonable maximum purchase price could be in the range of 600 to 800 euros. This is based on the fact that buyers are often willing to pay a little more than the starting price, especially if there is interest in the coin.

Therefore, an estimated maximum purchase price for this coin could be approximately 700 euros.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Current Condition: The coin has a condition rating of 75 (MBC), indicating that it is in acceptable shape, but not in the best condition.

2. Auction History:
- The average starting price in previous auctions is 937.46 euros, and the average hammer price is 1220.84 euros.
- In the past, hammer prices have varied significantly, ranging from 240 euros to 4019.51 euros, depending on the condition and demand at that time.

3. Price Trends:
- The last auction with a similar condition (75) had a hammer price of 276.35 euros, which may be a good indicator of the current market value.

4. Current Starting Price: The starting price is 640 euros, suggesting that the seller has expectations of a higher price, but it may also indicate that the market is not willing to pay that much.

Based on these factors, an estimated maximum purchase price could be positioned within a range between the average hammer price for similar conditions and the current starting price.

Given that the average hammer price for condition 75 has been approximately 276.35 euros in the last auction, and considering that the starting price is 640 euros, a reasonable maximum purchase price could be:

Estimated maximum purchase price: 800 - 1000 euros.

This range allows for a competitive offer without exceeding the historical value of the coin in similar conditions.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on the provided data:

1. Current Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in relatively good shape. This suggests that its value should be above coins in worse conditions.

2. Current Starting Price and Previous Prices: The current starting price is 1100 euros, and the average starting price in previous auctions is 3076.18 euros. This indicates that the current starting price is significantly lower than the historical average, which could represent a good buying opportunity.

3. Previous Hammer Prices: The average hammer price in previous auctions is 5461.79 euros. This suggests that, in general, coins of this reference tend to sell for much higher prices than the current starting price.

4. Sales Trends: Out of the 10 times it has been auctioned, it has sold 7 times, indicating good demand for this coin.

5. Comparison with Previous Prices: In the 2022 auction, a coin with a condition rating of 85 sold for 2400 euros. This suggests that a coin with a condition rating of 80 could have an estimated value in a similar range, although slightly lower.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 2400 to 3000 euros, considering that the condition is slightly lower than that of the coin that sold for 2400 euros and that the current starting price is quite low compared to the historical average.

Therefore, a reasonable maximum purchase price could be 2500 euros.

To estimate a maximum purchase price for the coin in question, we can consider several factors:

1. Condition: The coin to be auctioned has a condition of 70 (MS-). This is an important factor, as coins in better condition tend to fetch higher prices.

2. Previous Prices: By observing the hammer prices of coins with similar conditions, we can see that:
- In 2011, a coin with a condition of 75 sold for 336 euros.
- In 2012, the same condition (75) reached a price of 750 euros.
- In 2020, a coin with a condition of 70 sold for 100 euros.
- In 2022, a coin with a condition of 80 sold for 300 euros.

3. Starting Price and Average Prices: The starting price of the coin is 650 euros, and the average hammer price in previous auctions is 417.11 euros. This suggests that the starting price is relatively high compared to the average hammer price.

4. Sales Trends: The coin has been auctioned 12 times in the past, of which it has sold 8 times. This indicates that there is interest in the coin, but also that there is a 33% chance it has not sold, which may influence the perception of its value.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 400 to 600 euros, considering that the starting price is 650 euros and the average hammer price is 417.11 euros. However, given that the condition is 70, which is lower than other coins that have sold for higher prices, a reasonable maximum purchase price could be approximately 550 euros. This allows for some competition in the auction, but also reflects the reality of the market based on historical data.

To estimate a maximum purchase price for the coin with a grade of 80 (MBC+), we can analyze the historical data from previous auctions of coins with a similar grade and their hammer prices.

1. Relevant data from previous auctions:
- Coins with a grade of 80 (MBC+) have been auctioned several times. Some examples are:
- 2012-02-22: Hammer price 350 (grade 80)
- 2012-04-29: Hammer price not available (grade 80)
- 2012-12-01: Hammer price 373.37 (grade 80)
- 2019-05-29: Hammer price 680 (grade 75)
- 2023-03-22: Hammer price 360 (grade 75)

2. Price analysis:
- The highest hammer price for a grade of 80 (MBC+) was 680 euros.
- The lowest hammer price in this range was 350 euros.
- The general trend shows that hammer prices for similar grades range between 350 and 680 euros.

3. Additional considerations:
- The average hammer price for this particular coin is 1035.52 euros, indicating that, although there are examples of lower prices, the market may be willing to pay more for coins of this reference.
- Given that the coin has a starting price of 500 euros, it is reasonable to consider that the hammer price could be above this value, especially if there is interest in the auction.

4. Final estimation:
- Taking all these factors into account, an estimated maximum purchase price for this coin with a grade of 80 (MBC+) could be in the range of 600 to 800 euros. This is based on previous hammer prices and potential interest in the auction.

Therefore, a reasonable maximum purchase price could be 800 euros.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on the provided data:

1. Current Condition: The coin has a condition rating of 75 (MBC), indicating that it is in a medium-low state. This generally affects the price, as coins in better condition tend to fetch higher prices.

2. Current Starting Price and Historical Prices: The current starting price is 150 euros, and the average starting price in previous auctions is 389.49 euros, with an average hammer price of 534.64 euros. This suggests that, in general, coins of this reference tend to sell for significantly higher prices than their starting price.

3. Sales History: The coin has been auctioned 97 times, of which it has sold 77 times. This indicates good demand and a history of successful sales.

4. Previous Hammer Prices: Looking at previous hammer prices for coins with a similar condition (75), we can see that they have reached hammer prices that vary, but some have been quite high (for example, 595.61 euros in 2012).

5. Recent Trends: In the most recent auctions, hammer prices have shown a trend of being higher, which could indicate an increase in demand or in the value of the coin.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 300 to 450 euros. This is based on the average hammer price of similar coins and the historical hammer price data for coins in similar conditions.

Therefore, a reasonable maximum purchase price could be approximately 400 euros.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, taking into account the current condition of the coin (70, VF-) and the hammer prices from previous auctions.

1. Condition: The coin has a condition of 70, which is considered VF-. This suggests that its state is acceptable but not excellent. Generally, coins in better condition tend to reach higher prices.

2. Previous hammer prices: Looking at the hammer prices of coins with similar conditions:
- In 2020, a coin with a condition of 70 was auctioned for 110 euros.
- In 2013, a coin with a condition of 75 was auctioned for 462.4 euros.
- In 2019, a coin with a condition of 80 was auctioned for 340 euros.

3. Price trends: The average hammer price for previous auctions is 320.14 euros, indicating that, in general, coins of this reference tend to reach prices in that range.

4. Starting price: The current starting price is 300 euros, which is a good starting point. However, since the average hammer price is higher, it is reasonable to expect that the final hammer price will be higher.

5. Estimation: Considering all these factors, an estimated maximum purchase price could be in the range of 350 to 400 euros, taking into account that the condition is VF- and that there is a price history suggesting that coins in similar conditions have reached higher prices.

Therefore, an estimated maximum purchase price for this coin could be approximately 375 euros.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on the provided data:

1. Current starting price: 800 euros.
2. Condition of the coin: 85 (ebc-), indicating good condition, although not the best.
3. Auction history:
- It has been auctioned 5 times in the past, of which it has sold 3 times.
- The average starting price in previous auctions is 2045.3 euros, and the average hammer price is 3144.39 euros.
4. Previous prices:
- In 2012, it sold for 600 euros.
- In 2013, it sold for 6833.17 euros (condition 90).
- In 2013, it sold for 2000 euros (condition not specified).
- In 2015, a hammer price of 4334.7 euros was estimated (condition not specified).

Given that the current condition of the coin is 85, which is lower than 90 (which sold for 6833.17 euros), it is reasonable to expect that the hammer price will not reach that level. However, the average hammer price of 3144.39 euros suggests that there is significant potential for a higher selling price.

Taking all these factors into account, an estimated maximum purchase price could be in a range between the average hammer price and a bit more, considering the condition.

Therefore, an estimated maximum purchase price could be around 2500 to 3000 euros. This reflects a balance between the condition, the price history, and the current starting price.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on the provided data:

1. Starting price: 300 euros.
2. Current condition: 75 (MBC), which is a fairly good condition, although not the best.
3. Auction history:
- In 2011, the coin was auctioned with an estimated price of 698.26 euros and sold for 1617.02 euros, with a condition of 90.
- In 2015, the starting price was 384.3 euros, with a final price of 720.55 euros, although the condition is not specified.

4. Average final price: 1168.79 euros, which is significantly higher than the current starting price.

Given that the current condition of the coin is 75, which is lower than the previous auction conditions (90), it is reasonable to adjust the estimated price downward compared to previous final prices.

### Estimation of the maximum purchase price:
- Considering the average final price of 1168.79 euros and adjusting for condition, we could estimate that the maximum purchase price could be in a range between 50% and 70% of that price, given that the condition is not the best.

- Calculation:
- 50% of 1168.79 euros = 584.39 euros
- 70% of 1168.79 euros = 818.15 euros

Therefore, a reasonable estimated maximum purchase price for this coin, considering its condition and auction history, could be between 584 and 818 euros.

To be more conservative, you might consider a maximum purchase price of 800 euros.

To estimate a maximum purchase price for the coin in question, we can consider several factors:

1. Current Condition: The coin has a condition of 80 (MS+). This is an important factor, as coins in better condition tend to reach higher prices.

2. Auction History:
- The average hammer price for similar coins is 496.09 euros.
- In the past, coins with similar conditions (around 80-90) have sold for prices that varied considerably, but some examples are:
- In 2014, a coin with a condition of 90 was hammered at 880.58 euros.
- In 2015, a coin with a condition of 90 sold for 648.28 euros.
- In 2020, a coin with a condition of 85 sold for 420 euros.

3. Starting Price and Average Starting Price: The current starting price is 200 euros, and the average starting price in the past has been 241.29 euros.

4. Sales Trends: Of the 18 times it has been auctioned in the past, 15 have sold, indicating good demand.

Based on this data, an estimated maximum purchase price could be in the range of 400 to 600 euros, considering that a condition of 80 is quite good, but it does not reach the level of higher conditions that have achieved significantly greater prices.

Therefore, a reasonable estimated maximum purchase price could be approximately 500 euros.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Starting Price: 150 euros.
2. Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in good shape, which may increase its value.
3. Auction History: It has been auctioned 2 times in the past, of which it sold once and did not sell once. This suggests that there is interest in the coin, but also that there may be some resistance in the price.
4. Average Starting and Hammer Price: The average starting price is 135 euros and the average hammer price is 160 euros. This indicates that, generally, coins of this reference tend to sell around those prices.
5. Previous Hammer Price: In the 2014 auction, the coin sold for 160 euros, establishing a precedent for its value.

Given that the condition is good and the previous hammer price was 160 euros, an estimated maximum purchase price could be in the range of 160 to 180 euros, considering that interest in the coin may have increased since then and that the condition is favorable.

Therefore, an estimated maximum purchase price could be 170 euros. This allows for some margin for competition in the auction, but it is also based on historical data and the current condition of the coin.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on the provided data:

1. Current starting price: 650 euros.
2. Coin condition: 75 (MBC), which is a medium-good condition.
3. Auction history:
- In 2016, the coin was auctioned with a starting price of 1482.87 euros and was sold at the same price, indicating that the market valued that coin at that price at that time.
- In 2022, the same coin was auctioned with a starting price of 500 euros and was sold at the same price, suggesting that interest in that coin may have decreased or that the market was less active.

4. Average starting and final prices: The average starting price is 877.62 euros and the average final price is 991.44 euros, indicating that, in general, coins of this reference tend to sell above the starting price.

Given that the condition is the same as in previous auctions and considering the current starting price, an estimated maximum purchase price could be positioned between the average final price and the final price of the 2016 auction.

Therefore, an estimated maximum purchase price could be:

- Estimated range: Between 900 and 1100 euros.

This is based on the fact that the previous final price was 1482.87 euros, but also considering that the market may have changed and that the current starting price is 650 euros. A purchase price of around 1000 euros could be reasonable, given the history and condition of the coin.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on the provided data:

1. Current Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Current Listing Price and Previous Prices: The current listing price is 350 euros, which is significantly lower than the average listing price of 670.02 euros and the average auction price of 908.56 euros. This suggests that the listing price may be underestimated.

3. Auction History: In the past, the coin has had auction prices that varied considerably. For example, the highest recorded auction price is 450 euros (in 2013), but there is also an auction price of 2805 euros from a 2015 auction, although the latter seems to be an exceptional case.

4. Sales Trends: Out of the 7 times it has been auctioned, it has sold 5 times, indicating a consistent interest in the coin. This may influence demand and, therefore, the price.

5. Comparison with Average Prices: Given that the average auction price is 908.56 euros, and considering the current condition of the coin, an auction price that approaches this average could be reasonable.

Taking all these factors into account, an estimated maximum purchase price could be between 700 and 900 euros, considering that the condition is good and that interest in the coin appears to be solid. A price of 800 euros could be a reasonable target, as it falls in the middle of this range and aligns with the average auction price.

To estimate a maximum purchase price for the coin in question, we can consider several factors:

1. Current Condition: The coin has a condition rating of 95 (EF+), indicating that it is in very good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price for this coin is 214.14 euros.
- In the past, hammer prices have varied significantly, ranging from 40 euros to over 1900 euros, depending on the condition and demand at the time of the auction.

3. Recent Auction Prices:
- In recent auctions, hammer prices have been in the range of 70 to 245 euros for coins with similar conditions (for example, 95 and 80).

4. Starting Price: The starting price is 175 euros, which may influence the final price, as hammer prices are often higher than the starting price.

Taking these factors into account, an estimated maximum purchase price for this coin could be in the range of 250 to 300 euros, given its condition and the history of hammer prices. This is based on the trend that coins in similar conditions have reached hammer prices in that range in the past.

To estimate a maximum purchase price for the coin in question, we can analyze several factors:

1. Current Condition: The coin has a condition of 85 (ebc-), which indicates that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The coin has been auctioned 9 times, of which it has sold 6 times. This suggests that there is consistent interest in the coin.
- The average starting price in previous auctions is 68.48 euros, and the average hammer price is 66.16 euros. This provides context regarding the market value of the coin.

3. Previous Prices:
- Previous hammer prices varied, but there is a notable price of 93.81 euros in 2013 for a coin with the same condition (85).
- There is also a hammer price of 80 euros in 2015 for a coin with a condition of 90, indicating that the price may be sensitive to condition.

4. Current Starting Price: The starting price is 80 euros, which is a good starting point.

Given that the condition of the coin is good (85) and considering the previous hammer prices, an estimated maximum purchase price could be in the range of 90 to 100 euros. This is based on historical interest and the current condition.

Therefore, an estimated maximum purchase price could be 95 euros.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on the provided data:

1. Starting price: 200 euros. This is the initial price set for the auction.
2. Auction history: The coin has been auctioned 4 times in the past, of which it has sold 3 times. This indicates that there is interest in the coin.
3. Average hammer price: 140 euros. This is the average price at which the coin has sold in previous auctions.
4. Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in good condition, which may increase its value.
5. Previous prices: The previous hammer prices have been 140, 150, and 130 euros, suggesting that the value of the coin has fluctuated but has remained within a similar range.

Given that the condition of the coin is good (80), and considering the starting price of 200 euros, it is reasonable to think that the hammer price could be above the average of 140 euros, but it will not necessarily reach the starting price.

Taking all these factors into account, an estimated maximum purchase price could be between 160 and 180 euros. This reflects an increase over the average hammer price, but also considers that the starting price is higher and that the coin is in good condition.

Therefore, an estimated maximum purchase price could be 170 euros.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Current Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in relatively good shape, but not among the best qualities.

2. Starting Price: The starting price is 120 euros, which sets a baseline for the auction.

3. Sales History:
- The average hammer price in previous auctions is 128.77 euros.
- It has been auctioned 24 times, of which 15 have sold, indicating a sales rate of 62.5%. This suggests there is interest in the coin, but also that there is a 37.5% chance it has not sold, which may influence the perception of its value.

4. Previous Prices:
- In past auctions, hammer prices have varied significantly, ranging from 60 euros to 400 euros, depending on condition and other factors.
- The last auction with a hammer price of 400 euros was notably high, but there is no information on the condition of that coin.

5. Comparison with Similar Conditions:
- Coins with similar conditions (around 80) have had hammer prices ranging from 60 to 150 euros in the past.

Based on these factors, an estimated maximum purchase price could be in the range of 130 to 150 euros. This is based on the average hammer price and the condition of the coin. However, since the starting price is 120 euros, it is reasonable to consider that a hammer price around 140 euros could be a realistic target, assuming demand remains steady.

Therefore, an estimated maximum purchase price could be 140 euros.
