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 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.

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 600 euros, which is significantly higher than the average listing price of 278.76 euros. However, the average hammer price is 412.26 euros, suggesting that the market has been willing to pay less than the current listing price in previous auctions.

3. Sales History: The coin has sold in 4 out of the last 6 auctions, indicating a consistent interest in the coin. However, it should also be noted that there have been 2 occasions when it did not sell.

4. Previous Hammer Prices: Previous hammer prices varied, but the highest was 1100 euros in a recent auction with a condition of 95. This suggests that the price could increase significantly with better condition.

5. Price Trends: Observing previous hammer prices, the price has been increasing, especially in the more recent auctions. This could indicate an upward trend in interest for this coin.

Considering all these factors, an estimated maximum purchase price could be in the range of 600 to 800 euros, given that the listing price is 600 euros and the condition is good, but not exceptional. A price of 800 euros could be a reasonable limit, given the price history and current condition.

To estimate a maximum purchase price for the coin in question, let's consider the following factors:

1. Starting Price: 130 euros. This is the initial price set for the auction.
2. Condition: The coin has a condition rating of 85 (ebc-), indicating that it is in fairly good shape, although not the best possible condition.
3. Auction History: The coin has been auctioned once in the past but did not sell, which may indicate that interest in this coin is not very high or that the starting price is too high for potential buyers.
4. Average Hammer Price: There is no data on previous sales, making it more difficult to establish a reference price.

Since the coin did not sell in its first auction and considering its condition, an estimated maximum purchase price could be slightly below the starting price to attract potential buyers.

Therefore, an estimated maximum purchase price could be between 100 and 120 euros, depending on the interest of collectors and the market at the time of the auction.

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

1. Starting Price: 80 euros. This is the initial price set for the auction.
2. Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in good condition. This generally increases its value compared to coins of lower condition.
3. Auction History: The coin has been auctioned 2 times in the past, of which it sold 1 time and did not sell 1 time. This suggests that there is interest in the coin, but also that there may be limitations in demand.
4. Previous Prices: In the previous auction, the coin was offered with a starting price of 30 euros and sold for the same price. This indicates that the market has valued this coin in a lower range in the past.

Given that the current starting price is 80 euros and considering the condition and auction history, an estimated maximum purchase price could be in a range between the starting price and the average hammer price of previous auctions.

Taking all these factors into account, an estimated maximum purchase price could be approximately 70-90 euros. This allows for some margin for competition in the auction, but also considers the price history and the 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. Coin 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. Previous Prices: By looking at previous auction prices for coins with similar conditions (80 and 85), we can see that auction prices have varied. For example:
- In 2015, a coin with a condition of 80 was auctioned for 230.11 euros.
- In 2022, a coin with a condition of 80 was auctioned for 190 euros.

3. Average Auction Price: The average auction price for this coin is 165.49 euros, providing an additional reference point.

4. Current Starting Price: The starting price is 400 euros, which is significantly higher than previous auction prices. This may indicate that the seller has high expectations, but it could also suggest that the market is willing to pay more for this particular coin.

5. Market Trends: Given that the coin has been auctioned 20 times in the past and has a 70% sell-through rate, this suggests there is consistent interest in this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 200 to 300 euros, considering that this is a more realistic price compared to the starting price of 400 euros. This also takes into account the auction price history and the coin's condition.

Therefore, an estimated maximum purchase price could be 250 euros.

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

1. Starting price: 850 euros.
2. Coin condition: 70 (MBC-), indicating a fairly good condition.
3. Auction history:
- It has been auctioned 8 times, of which it has sold 6 times.
- The average hammer price in previous auctions is 518.1 euros, but it should be noted that the current starting price is significantly higher.
- In previous auctions, hammer prices have varied, with a maximum price of 1172.41 euros in 2015 for a coin with similar condition (75).

4. Price trends:
- The general trend seems to be that hammer prices have been increasing, especially for coins in good condition.
- The last auction with a hammer price of 1172.41 euros suggests that there is a market willing to pay high prices for well-preserved coins.

Given that the condition of the current coin is 70 (MBC-), which is lower than the condition of 75 from the highest auction, but still represents good condition, we can estimate a maximum purchase price.

Estimation of the maximum purchase price:
- Considering the starting price of 850 euros and the history of hammer prices, a reasonable maximum purchase price could be in the range of 900 to 1100 euros, depending on the demand at the auction.

Therefore, an estimated maximum purchase price could be approximately 1000 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 quite good shape. This can positively influence its value.

4. Previous Prices: Looking at previous hammer prices, the highest recorded price was 375 euros in 2013, although this may be an exceptional case. More recent and relevant hammer prices (such as 64.72 euros in 2015 and 110 euros in 2020) are more representative of the current value.

5. Market Trends: Given that the average hammer price is 123.89 euros and considering that the current condition is good, it is reasonable to think that the price could be in a similar or slightly higher range.

Taking all these factors into account, an estimated maximum purchase price could be between 150 and 200 euros. This would allow for competitive bidding in the auction without exceeding the historical hammer value and considering the good 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:

3. Average Auction Price: The average auction price for similar coins is 645.58 euros, indicating that, in general, coins of this reference tend to reach high prices.

4. Starting Price: The starting price is 250 euros, which may indicate a reasonable initial price, but not necessarily the final price.

5. Sales Trends: The coin has sold in 15 of the last 18 auctions, suggesting there is consistent interest in this coin.

Based on these factors, especially considering the condition rating of 80 (VF+) and previous auction prices, an estimated maximum purchase price could be in the range of 600 to 800 euros. This is based on the fact that coins in similar conditions have reached auction prices in that range, and given that the condition of this coin is good, it could attract collectors willing to pay a higher price.

Therefore, an estimated 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 85 (ebc-), indicating that it is in quite good shape. This generally translates to a higher price compared to coins in lower condition.

2. Starting Price and Average Hammer Price: The starting price is 130 euros, and the average hammer price in previous auctions is 185.65 euros. This suggests that, in general, coins of this reference tend to sell for above the starting price.

3. Auction History: In the past, the coin has had hammer prices that varied significantly. For example, in 2012 it sold for 360 euros, which is an exceptionally high price, but there are also lower hammer prices, such as 88 euros in 2019. However, the average hammer price is a good indicator of what can be expected.

4. Sales Trends: The coin has been auctioned 7 times, of which 6 have sold. This indicates good demand and consistent interest in the coin.

Given all this, an estimated maximum purchase price could be set in a range that considers the average hammer price and the current condition.
