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 80 (MS+), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price for coins with a similar condition (80) has been approximately 83.83 euros.
- In previous auctions, hammer prices for coins with a condition of 80 have varied, reaching up to 140 euros at best (as seen in the auction on November 10, 2020).

3. Starting Price and Average Starting Price: The current starting price is 60 euros, which is slightly higher than the average starting price of 49.41 euros. This suggests that the seller has expectations of a higher price due to the condition.

4. Recent Trends: In the most recent auctions, the hammer price has been in the range of 100 to 130 euros for coins with similar conditions.

Based on these factors, an estimated maximum purchase price for this coin could be between 100 and 140 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate.

Therefore, a reasonable maximum purchase price could be 120 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 85 (ebc-), indicating that it is in quite good shape. This is important because coins in better condition tend to fetch higher prices at auctions.

2. Auction History:
- The average hammer price for this coin in the past has been 157.17 euros.
- Hammer prices have varied significantly, ranging from 40 euros to 900 euros, depending on the condition and demand at the time of the auction.
- In recent auctions, hammer prices of 220 euros (condition 90) and 180 euros (condition 80) have been reached.

3. Starting Price: The current starting price is 175 euros, indicating that the seller has expectations of a relatively high hammer price.

4. Price Trends: In the most recent auctions, hammer prices have shown a trend of being higher, especially for coins in good condition.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 250 to 300 euros. This range takes into account the good condition of the coin and the hammer prices achieved in previous auctions for coins of similar condition.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, including the current starting price, the current grade, and previous auction prices.

1. Current starting price: 4000 euros.
2. Current grade: 75 (MBC).
3. Previous auction prices:
- 2013 (75): 12007.79
- 2014 (80): 15843.65
- 2014 (75): 17000
- 2015: 9632.68 (no specified grade)
- 2016 (30): 16565.2 (low grade)
- 2024 (75): 4800 (recent auction price)

4. Average auction price: 11664.19 euros.

Given that the grade of the coin is 75, which is an acceptable level, and considering that it has sold for significantly higher prices in previous auctions, we can make an estimation.

The highest auction price for a coin with a similar grade (75) was 17000 euros. However, the most recent auction price was 4800 euros, indicating that the market may be fluctuating.

Taking into account the starting price of 4000 euros and the average auction price of 11664.19 euros, an estimated maximum purchase price could be positioned between the starting price and the highest previous auction price.

Maximum purchase estimate: It may be reasonable to consider a maximum purchase price of around 12000 euros, as it is an intermediate value between the highest auction price and the average auction price, adjusted for the current grade.

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

1. Current Condition: The coin has a condition of 75 (MBC), indicating an average state of preservation. This is important because the price of coins often varies significantly based on their condition.

2. Auction History:
- The average hammer price for similar coins has been 687.53 euros.
- In previous auctions, the hammer prices for coins with a similar condition (75) have varied, with the highest being 2200 euros and the lowest 340 euros.
- The last auction of a coin with a condition of 75 had a hammer price of 240 euros.

3. Starting Price: The current starting price is 350 euros, which is a reasonable starting point.

4. Sales Trends: Of the 20 times this coin has been auctioned, it has sold 16 times, indicating good demand.

5. Comparison with Previous Prices:
- In 2014, a coin with a condition of 85 sold for 532.22 euros, suggesting that the price may be higher for coins in better condition.
- In 2016, a coin with a condition of 75 sold for 340 euros, setting a precedent for the hammer price in this condition.

Taking all these factors into account, an estimated maximum purchase price for this coin could be in the range of 500 to 700 euros, considering that the average hammer price is 687.53 euros and that condition is a key factor.

Therefore, a reasonable maximum purchase price could be 650 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+). This is an important factor, as coins in better condition tend to fetch higher prices.

2. Starting Price and Average Hammer Price: The starting price is 700 euros, and the average hammer price in previous auctions is 949.22 euros. This suggests that, in general, coins of this reference tend to sell for above their starting price.

3. Sales History: The coin has been auctioned 31 times, of which it has sold 26 times. This indicates good demand and a history of successful sales.

4. Previous Prices: By looking at previous hammer prices for coins with similar conditions (around 80), we can see that they have reached hammer prices that varied, but some have exceeded 600 euros. For example, in 2019, a coin with a condition of 85 sold for 620 euros.

5. Price Trends: In recent auctions, hammer prices for coins with similar conditions have been in the range of 600 to 900 euros, and in some cases, even higher.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 900 to 1100 euros, considering that the average hammer price is 949.22 euros and that a condition of 80 may attract collectors willing to pay a bit more for a coin in good condition.

Therefore, an estimated maximum purchase price could be approximately 1000 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 (FDC).

2. Starting Price: The starting price is 1500 euros, which serves as a baseline for the auction.

3. Sales History:
- The average hammer price in previous auctions is 4632.75 euros, suggesting that, in general, coins of this reference tend to sell for significantly higher prices than the starting price.
- The coin has been auctioned 41 times, with 37 sales, indicating a consistent interest in this coin.

4. Previous Prices:
- There are several previous hammer prices that vary considerably, ranging from 850 euros to 32000 euros, depending on the condition and other factors.
- The last auction with a similar condition (80) had a hammer price of 2500 euros.

5. Recent Trends: In the most recent auctions, hammer prices have been in the range of 1800 to 2500 euros for similar conditions.

Based on this data, an estimated maximum purchase price could be set in a range between 2500 and 3000 euros, considering that the condition is good and that there is high interest in the coin. However, since the starting price is 1500 euros, it is likely that the final hammer price will be closer to this upper range.

Therefore, a reasonable estimated maximum purchase price could be 3000 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 of 75 (MBC), indicating a medium-good quality. This generally translates to a higher price than coins of lower condition, but lower than those of superior condition.

2. Auction History:
- The average hammer price for this coin in the past is 2785.83 euros.
- The average starting price is 2023.43 euros.
- Coins of similar condition (75) have been auctioned in the past, with hammer prices varying, but some reaching significant figures (for example, 1500 euros in 2011 and 2000 euros in 2012).

3. Recent Trends: In the most recent auctions, hammer prices for coins of similar condition have been in the range of 1500 to 5000 euros, depending on demand and other market factors.

4. Current Starting Price: The starting price is 900 euros, suggesting that the seller has expectations of a higher hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 3000 to 4000 euros, considering that the average hammer price is 2785.83 euros and that the condition of the coin is good. This also takes into account the possibility that interest in the coin may increase at auction, potentially leading to a higher hammer price.

Therefore, a reasonable maximum purchase price could be 3500 euros.

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

1. 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 with lower conditions.

- The highest recorded auction for this coin was 1100 euros in 2020, although the condition of that coin is not specified.

4. Current Starting Price: The starting price is 600 euros, indicating that the seller has expectations of a high hammer price.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 700 to 800 euros, considering that the condition is good and there is a history of hammer prices supporting this estimate. However, given the interest in the coin and the starting price, a price of up to 900 euros could be reasonable when considering competition in the auction.

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

1. Current Condition: The coin has a condition of 80 (MS+), indicating that it is in fairly good shape, but not the best possible condition.

2. Current Listing Price and Historical Prices: The current listing price is 2000 euros, and the average hammer price in previous auctions is 3518.3 euros. This suggests that, in general, the coin tends to sell for a price higher than the listing price.

3. Previous Hammer Prices: Looking at previous hammer prices, there are several examples of prices exceeding 3000 euros, especially for coins in better condition. For instance, in 2013, a coin with a condition of 90 sold for 11873.65 euros.

4. Market Trends: The general trend seems to be that coins in better condition (90 or higher) reach significantly higher prices. However, coins with a condition of 80 have also shown hammer prices around 3000 euros in the past.

5. Data-Based Estimation: Given that the average hammer price is 3518.3 euros and considering that the condition of this coin is lower than some that have sold for higher prices, an estimated maximum purchase price could be in the range of 3000 to 4000 euros.

Conclusion: Based on the information provided, an estimated maximum purchase price for this coin could be approximately 3500 euros. This reflects a balance between the current condition and historical hammer prices.

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

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

2. Auction History:
- In 2011, a coin with a condition of 75 sold for 2200 euros.
- In 2015, although the exact condition is not known, the final price was 22000 euros with a starting price of 12000 euros.
- In 2018, another coin with a condition of 75 sold for 1600 euros.

3. Average Hammer Price: The average hammer price for similar coins is 8600 euros, indicating that there is a market willing to pay high prices for coins of this reference.

4. Current Starting Price: The starting price is 1000 euros, which may attract more bidders.

5. Market Trends: Since the coin has been auctioned several times and has had a considerably high average hammer price, this suggests that there is sustained interest in this reference.

Based on these factors, an estimated maximum purchase price could be in the range of 2000 to 3000 euros, considering that the current condition is lower than the coins that have sold in the past for higher prices. However, given the market interest and the average hammer price, a reasonable maximum purchase price could be approximately 2500 euros.

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

1. Starting Price: 700 euros. This is the initial price set for the auction.
2. Condition: The coin has a condition rating of 30 (BC+), indicating that it is in fairly low condition. This generally negatively affects the price, as coins in better condition tend to fetch higher prices.
3. Auction History: The coin has been auctioned once in the past but did not sell, suggesting that interest in this coin may be limited or that the starting price is too high for its condition.
4. Average Hammer Price: There is no data on previous sales, making it difficult to estimate a realistic hammer price.

Since the coin did not sell in its first auction and considering its condition, it is likely that buyer interest is low. Therefore, a reasonable maximum purchase price could be a percentage of the starting price, adjusted for condition.

A conservative estimate could be between 50% and 70% of the starting price, given the condition. This leads us to a range of:

- 50% of 700 euros = 350 euros
- 70% of 700 euros = 490 euros

Thus, an estimated maximum purchase price could be around 400 to 490 euros. This would allow a potential buyer to take into account the risk that the coin may not sell in the future and its condition.

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

1. Starting price: 80 euros.
2. Average hammer price: 85 euros, indicating that in the only previous auction, the coin sold for a price slightly higher than the starting price.
3. Condition: The coin has a condition rating of 85 (ebc-), which is a good state and may positively influence its value.
4. Auction history: The coin has been auctioned once and sold on that occasion, suggesting there is interest in it.

Given that the average hammer price is 85 euros and considering that the condition is good, an estimated maximum purchase price could be slightly higher than the average hammer price, but not too much, to avoid the risk of overpaying.

Therefore, an estimated maximum purchase price could be between 90 and 95 euros. This would allow for competition in the auction without exceeding a reasonable limit based on the price history and the condition of the coin.

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 (MS+), indicating that it is in fairly good shape, but not the best possible condition.

2. Auction History:
- The average hammer price in previous auctions is 386.12 euros.
- The coin has been auctioned 14 times, of which it has sold 8 times, indicating a sell-through rate of 57.14%. This suggests that there is interest in the coin, but also that there is a 42.86% chance it has not sold, which may influence the perception of its value.

3. Previous Prices:
- Previous hammer prices have varied, but there is a notable price of 950 euros for a condition of 90, indicating that the value can increase significantly with better condition.
- Overall, hammer prices for similar conditions (80) have ranged from 240 to 600 euros.

4. Current Starting Price: The starting price is 150 euros, which is relatively low compared to the average hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 300 to 400 euros, considering that the condition is good but not excellent, and that the interest in the coin seems to be moderate. A price of 350 euros could be a reasonable benchmark for a competitive offer.

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

1. Current starting price: 90 euros.
2. Coin condition: 90 (EBC), indicating good condition.
3. Auction history:
- It has been auctioned 16 times, of which it has sold 13 times.
- The average hammer price in the past is 149.32 euros.
- In previous auctions, the hammer price has varied, with a maximum of 406.86 euros in 2016 for a coin with a condition of 90.

4. Recent hammer prices:
- In October 2022, a coin with a condition of 90 was auctioned and sold for 340 euros.
- In other auctions, hammer prices have ranged between 65 and 406.86 euros, depending on condition and demand.

Given that the coin to be auctioned has a condition of 90 and considering the hammer price history, an estimated maximum purchase price could be set in a range between the average hammer price (149.32 euros) and the highest recorded price (406.86 euros).

However, since the starting price is 90 euros and considering that the average hammer price is significantly higher, a reasonable maximum price could be:

Estimated maximum purchase price: 300 euros.

This price reflects a balance between the hammer price history and the current condition of the coin.

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 85 (EF-), indicating that it is in fairly good shape, but not the best possible condition (UNC).

2. Starting Price: The starting price is 60 euros, which can be a good starting point for the auction.

3. Sales History:
- The average hammer price in previous auctions is 300.19 euros, suggesting that, in general, coins of this reference tend to sell for significantly higher prices than their starting price.
- The coin has been auctioned 42 times, of which it has sold 35 times, indicating good demand.

4. Previous Prices:
- In previous auctions, hammer prices have varied considerably, ranging from 44 euros to 1752.31 euros, depending on the condition and other factors.
- The last auction with a similar condition (85) had a hammer price of 90 euros.

5. Market Trends: Given that the average hammer price is quite high compared to the starting price, and considering that the condition of the coin is good, it is reasonable to assume that interest in this coin could lead to a hammer price above the average price.

Based on these factors, an estimated maximum purchase price could be in the range of 250 to 350 euros, considering that the average hammer price is 300.19 euros and that the condition of the coin is quite good.

Therefore, a reasonable maximum purchase price could be 350 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: 60 euros. This is the initial price of the auction.
2. Condition: The coin has a condition rating of 85 (ebc-), indicating that it is in quite good shape. This generally increases its value compared to coins with lower conditions.
3. Auction History:
- It has been auctioned 3 times in the past, of which it has sold 2 times and not sold 1 time.
- The average starting price in previous auctions is 82.52 euros, and the average hammer price is 98.79 euros.
- In previous auctions, the hammer prices were 97.57 euros (condition 16) and 100 euros (condition 80).

Given that the current condition of the coin is better than that of previous auctions (85 compared to 80 and 16), we can infer that the hammer price could be higher than before.

### Estimated Maximum Purchase Price:
- Considering the average hammer price of 98.79 euros and the fact that the condition is better, an estimated hammer price could be in the range of 100 to 110 euros.
- However, since the starting price is 60 euros, bidders are likely to be willing to pay more, but they may not necessarily reach the previous average hammer price.

Therefore, an estimated maximum purchase price could be around 100-110 euros, taking into account the good condition and the price history.

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

3. Auction History: The coin has been auctioned 45 times, of which it has sold 28 times. This suggests that there is consistent interest in the coin, which may increase its value.

4. Previous Prices: Looking at previous hammer prices, there are several examples of prices exceeding 100 euros, with some reaching much higher figures (for example, 22,000 euros in a recent auction). However, these extreme prices may be exceptional and not necessarily representative of the overall value.

5. Starting Price: The current starting price is 90 euros, which may be a good starting point for the auction.

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

Estimated Maximum Purchase Price:

We could consider a maximum purchase price around 1,000 euros, as it is above the average hammer price and reflects the good condition of the coin. However, it is important to keep in mind that the final price will depend on the competition in the auction and the interest of collectors at that time.

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