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 30 (BC+), indicating that it is not in the best shape. This generally reduces its value compared to coins in better condition.

2. Current Listing Price and Historical Prices: The current listing price is 90 euros, and the average hammer price in previous auctions is 231.65 euros. However, hammer prices vary depending on the condition of the coin.

3. Price Trends: Looking at the hammer prices of coins with similar conditions (around 70-80), the hammer prices have ranged between 100 and 500 euros in previous auctions. However, coins in better condition tend to reach higher prices.

4. Analysis of Previous Sales: The coin has been sold 23 times in the past, indicating consistent interest. The average hammer price of 231.65 euros suggests that, despite the condition, there is a market for this coin.

5. Condition-Based Estimation: Given that the current condition is 30, it is reasonable to adjust the expected hammer price downward. If we consider that coins in BC+ condition typically sell for 30-50% less than those in average condition (70-80), we could estimate a hammer price in the range of 100-150 euros.

Conclusion: Based on these factors, an estimated maximum purchase price for this coin could be between 120 and 150 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 85 (ebc-), which indicates that it is in quite good shape. This generally translates to a higher value compared to coins with lower conditions.

2. Auction History:
- The average hammer price in previous auctions is 47.22 euros.
- In past auctions, hammer prices of up to 180 euros have been reached for coins with similar conditions (for example, 95).
- The last auction where a similar coin with a condition of 90 was sold reached a price of 55 euros.

3. Starting Price and Average Starting Price:
- The current starting price is 25 euros, and the average starting price in previous auctions is 28.93 euros.

4. Sales Trends: The coin has been sold in 76% of the auctions it has participated in, indicating good demand.

Based on these factors, an estimated maximum purchase price could be in the range of 70 to 90 euros. This is based on the fact that the condition is good and there are precedents for higher hammer prices in the past. However, since the starting price is 25 euros, it is likely that the final price will not significantly exceed this range unless there is strong competition in the auction.

Therefore, a reasonable estimated maximum purchase price could be 80 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 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.

2. Auction History:
- The average hammer price in the past has been 56.73 euros.
- The coin has been auctioned 27 times, of which 22 have been successful sales. This suggests there is consistent interest in this coin.
- Previous hammer prices for coins with similar conditions (around 80-85) have varied, but some have reached up to 140 euros in optimal conditions.

3. Starting Price and Average Starting Price:
- The current starting price is 30 euros, and the average starting price in the past has been 27.6 euros. This indicates that the current starting price is reasonable and could attract bidders.

4. Price Trends:
- In previous auctions, hammer prices have shown a considerable range, but generally, coins in similar conditions have reached hammer prices that exceed the starting price.

Based on these factors, an estimated maximum purchase price could be in the range of 70 to 90 euros, considering that the condition is good and that interest in the coin has been consistent. This also takes into account that the average hammer price has been 56.73 euros, suggesting that bidders are willing to pay more than the starting price under favorable conditions.

Therefore, a reasonable maximum purchase price could be 80 euros.

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

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

2. Previous Auction Prices:
- In previous auctions with a condition of 90, the hammer prices have been:
- 180 euros (2020-12-17)
- 170 euros (2019-04-25)
- 160 euros (2023-03-16)

3. Price Trends:
- The average hammer price for this coin is 87.93 euros, but the highest hammer prices for similar conditions are significantly higher.

4. Starting Price: The starting price is 90 euros, suggesting that the seller has expectations of a higher hammer price.

5. Competition Analysis: Given that there have been 17 previous auctions and 15 sales, demand seems to be good, which may influence a higher hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 160 to 180 euros, considering that in previous auctions with the same condition those prices have been reached. Therefore, a reasonable maximum purchase price could be:

Estimated maximum purchase price: 180 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 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. Current Starting Price and Previous Prices: The current starting price is 40 euros, and the average hammer price in previous auctions is 36.64 euros. However, in recent auctions, we have seen hammer prices reaching up to 95 euros.

3. Price Trends: By observing the hammer prices of coins with similar conditions (around 80-95), we can see that prices have fluctuated but have reached higher figures in the past. For example, in 2023, a coin with a condition of 95 was sold for 60 euros.

4. Demand and Supply: The coin has been auctioned 23 times, of which it has sold 22 times, indicating good demand. This can influence the hammer price.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 70 to 90 euros, considering that the condition is high and there are precedents for hammer prices in that range. A price of 80 euros could be a reasonable target, as it falls in the middle of that range and reflects the good condition of the coin.

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

1. Coin 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 coin has been auctioned 77 times, of which it has sold 70 times. This suggests good demand and sustained interest in the coin.

3. Previous Prices: By looking at previous auction prices for coins with a similar condition (80), we can see that the hammer prices have varied. For example:
- In a 2020 auction, a coin with a condition of 80 sold for 75 euros.
- In another auction in 2022, a coin with a condition of 80 sold for 100 euros.

4. Average Hammer Price: The average hammer price for this coin is 58.22 euros, providing an additional benchmark.

5. Starting Price: The starting price is 30 euros, indicating that the seller expects a lower price initially, but this does not necessarily reflect the true value of the coin.

Taking all these factors into account, an estimated maximum purchase price could be between 80 and 100 euros, given that there are examples of previous auctions in this range and the coin's condition is good. Therefore, a reasonable maximum purchase price could be 90 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 30 (BC+), which is significantly lower than previous conditions that ranged between 70 and 75. This suggests that the value of the coin will be lower compared to previous auctions.

2. Previous Auction Prices: Previous hammer prices for coins with conditions of 70 and 75 have been considerably higher, ranging from 95 to 190 euros. However, since the current condition is much lower, it is reasonable to expect that the hammer price will also be lower.

3. Starting Price and Average Hammer Price: The current starting price is 60 euros, and the average hammer price for similar coins in the past has been 130.63 euros. However, given that the condition is lower, the expected hammer price should be adjusted downward.

4. Sales Trends: The coin has been auctioned 9 times, of which it has sold 8 times, indicating a consistent interest in the coin, although the current starting price is lower than the historical average.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 70 to 90 euros. This is based on the need to adjust the price downward due to the current condition, while also recognizing the interest in the coin and previous hammer prices for higher conditions.

Therefore, a reasonable maximum purchase price could be 80 euros.

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

1. Starting Price: 2500 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, but not the best possible condition.
3. Auction History: The coin has been auctioned 2 times in the past, of which it sold once for 2300 euros. This suggests that the market has valued this coin around that price in the past.
4. Average Hammer Price: 2300 euros, which is the average price at which similar coins have sold in the past.
5. Average Starting Price: 2000 euros, indicating that generally, coins of this reference tend to start auctioning at a lower price.

Given that the starting price is 2500 euros, which is higher than the average hammer price of 2300 euros, and considering that the coin has a condition rating of 85, an estimated maximum purchase price could be around 2300 euros, which is the price it has previously sold for.

However, since the starting price is 2500 euros, some bidders may be willing to pay a bit more, especially if there is interest in the coin. Therefore, a reasonable maximum purchase price could be approximately 2400 euros. This allows for some competition in the auction while remaining below the starting price.

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

1. Current Condition: The coin has a condition of 75 (MBC), which indicates that it is in quite good shape. This generally increases its value compared to coins with lower conditions.

2. Auction History:
- In the auction on December 16, 2020, the coin was auctioned with a starting price of 200 euros and sold for 200 euros, indicating that there was no increase in price on that occasion.
- In the auction on March 6, 2024, the condition was 70, and there is no information on the final price, but the starting price was 200 euros.

3. Average Hammer Price: The average hammer price for this coin has been 255 euros, suggesting that, in general, buyers are willing to pay more than the starting price.

4. Demand and Supply: Since it will not be auctioned in the coming days and there has been prior interest (2 sales out of 3 auctions), this may indicate that there is a market for this coin.

Based on these factors, an estimated maximum purchase price could be positioned between the average hammer price (255 euros) and a bit more, considering the current condition and interest in the coin.

Therefore, an estimated maximum purchase price could be around 280-300 euros. This takes into account the good condition and price history, but it is also wise not to exceed the average hammer price too much to avoid overpaying.

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

1. Current Condition: The coin has a condition of 75 (MBC), which is a fairly good state. This suggests that its value should be in a medium-high range.

2. Auction History:
- The average hammer price from previous auctions is 399.29 euros, indicating that, in general, coins of this reference tend to sell for prices above their starting price.
- In previous auctions, hammer prices have varied, but there are examples of sales exceeding 500 euros, especially in similar conditions.

3. Current Starting Price: The starting price is 250 euros, which is reasonable given the history of hammer prices.

4. Price Trends: Looking at previous hammer prices, the highest recorded price was 650 euros in an auction with a condition of 80. This suggests that, although the current coin's condition is slightly lower, it could still reach a significant price.

5. Estimation: Given that the average hammer price is 399.29 euros and considering that the condition is 75, an estimated maximum purchase price could be between 400 and 500 euros, taking into account that the market can be competitive and there is a history of high prices.

Therefore, an estimated maximum purchase price for this coin could be approximately 450 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: 250 euros.

3. Condition of the coin: 90 (EF), which is a fairly good condition.
4. Auction history: The coin has been auctioned 2 times in the past and has sold on both occasions, indicating a consistent interest in the coin.

Given that the average auction price has been 300 euros and considering that the condition is good (90), an estimated maximum purchase price could be in a range above the starting price, but not too far above the average auction price.

Taking these factors into account, an estimated maximum purchase price could be approximately 320 euros. This is based on the previous average auction price and the good 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 quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price for similar coins has been 109 euros.
- In previous auctions, coins with a similar condition (85) have reached hammer prices of up to 140 euros (as seen in the auction on 2019-10-17).
- The last auction with a condition of 85 had a hammer price of 75 euros (2022-10-17).

3. Starting Price and Average Starting Price: The current starting price is 60 euros, and the average starting price in the past has been 64.05 euros. This suggests that the starting price is reasonable and aligns with historical expectations.

4. Sales Trends: The coin has been sold in 35 out of 40 auctions, indicating good demand. This may influence a higher hammer price.

5. Previous Estimates: In past auctions, the estimated price for coins with similar conditions has varied, but it has reached up to 150 euros in some cases.

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 can consider several factors based on the provided data:

1. Current Condition: The coin has a condition rating of 90 (EF), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Previous Prices: By looking at previous auction prices for coins with similar conditions, we can see that:
- In 2019, a coin with a condition of 95 sold for 160 euros.
- In 2018, a coin with a condition of 80 sold for 120 euros.
- In 2019, a coin with a condition of 85 sold for 76 euros.

3. Average Auction Price: The average auction price for this coin is 82.19 euros, which is also a good indicator of the expected value.

4. Starting Price: The starting price is 75 euros, suggesting that the seller expects a reasonable price, but it may not reflect the true market value of the coin.

5. Auction Trends: The coin has been auctioned 18 times, of which 17 have sold. This indicates good demand and consistent interest in the coin.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 100 to 130 euros, considering that the condition is good and that previous auction prices for coins of similar condition have been higher.

Therefore, a reasonable maximum purchase price could be 120 euros.

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

1. Starting price: 60 euros.
2. Average hammer price: 90 euros. This indicates that, in the past, the coin has had good interest and has reached a price higher than the starting price.
3. Condition: The coin has a condition rating of 70 (VF-), which suggests that it is in quite good shape, potentially increasing its value.
4. Auction history: It has been auctioned once and sold on that occasion, indicating that there is demand for this coin.

Given that the average hammer price is 90 euros and considering that the condition is good, an estimated maximum purchase price could be in the range of 90 to 120 euros. This is because, depending on demand and condition, collectors might be willing to pay a little more.

Therefore, an estimated maximum purchase price could be 100 euros. This allows for some margin for competition in the auction, but it is also based on the price history and the condition of the coin.

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

1. Starting price: 75 euros.
2. Coin condition: 70 (MBC-), indicating an average condition.
3. Average hammer price in previous auctions: 103.6 euros.
4. Price history:
- In 2018, with a condition of 70, it was sold for 60 euros.
- In 2018, with a condition of 80, it was sold for 128 euros.
- In 2014, there is no information on condition, but it was sold for 60 euros.
- In 2020, there is no information on condition, but it was sold for 110 euros.

Given that the condition of the current coin is 70, which is similar to the first auction in 2018 where it sold for 60 euros, and considering that the average hammer price is 103.6 euros, we can infer that the hammer price could be in a range between 60 and 110 euros.

However, since the average hammer price is significantly higher and the coin has a starting price of 75 euros, an estimated maximum purchase price could be around 100 euros, taking into account that collector interest and demand may influence the final price.

Therefore, an estimated maximum purchase price could be 100 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 30 (BC+), which indicates that it is not in very good shape. This will affect its value compared to coins in better condition.

2. Previous Prices: By looking at previous auction prices, we can see that the coin has reached auction prices of up to 480 euros in much better conditions (such as in 2021 with a condition of 85). However, in conditions similar to the current one (condition of 30), the lowest auction price was 90 euros in 2019.

3. Starting Price and Average Auction Price: The current starting price is 75 euros, and the average auction price in the past has been 265.71 euros. However, given that the current condition is quite low, it is unlikely that this average will be reached.

4. Auction Trends: Since the coin has sold every time it has been auctioned, this suggests that there is consistent interest in the coin, although the condition may limit the price.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 90 to 150 euros, considering that the lowest auction price in similar conditions was 90 euros and that interest in the coin could allow for a slight increase in price.

Therefore, a reasonable maximum purchase price could be 150 euros.

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

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

- In 2020, a coin with a grade of 80 sold for 290 euros.
- In 2022, a coin with a grade of 75 sold for 655 euros.

3. Average Auction Price: The average auction price for this coin is 364.14 euros, indicating that, in general, coins of this reference tend to sell for relatively high prices.

4. Starting Price: The current starting price is 125 euros, which may indicate a low initial price compared to previous auction prices.

5. Market Trends: Given that there has been an increase in auction prices in recent years, it is reasonable to assume that interest in this coin may be on the rise.

Based on these factors, an estimated maximum purchase price for the coin could be between 300 and 400 euros, considering that the grade is a limiting factor and that the highest auction price for a similar grade was 360 euros. Therefore, a reasonable maximum purchase price could be approximately 350 euros.

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

### Estimation of Maximum Purchase Price
Taking all these factors into account, an estimated maximum purchase price for this coin could be in the range of 400 to 600 euros, considering that the condition is good and that previous hammer prices have reached similar figures.

Therefore, a reasonable maximum purchase price could be approximately 500 euros. This is based on the trend of previous hammer prices and the current condition of the coin.

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

1. Current Condition: The coin has a condition of 70 (MS-). This indicates that it is in an acceptable state, but not of high quality. Coins with a similar condition have had auction prices that vary, but are generally below those with a higher condition.

2. Previous Auction Prices: By observing the auction prices of coins with a similar condition (70), we find that they have reached auction prices of up to 300 euros in recent auctions. For example, at the auction on 2023-12-13, the coin with a condition of 70 was sold for 300 euros.

3. Average Auction Price: The average auction price for this coin is 416.09 euros, suggesting that, in general, coins of this reference tend to sell for higher prices, but this may be influenced by coins in better condition.

4. Starting Price: The current starting price is 125 euros, which is relatively low compared to previous auction prices.

5. Auction Trends: The coin has been auctioned 52 times, with a high percentage of sales (48 out of 52). This indicates a consistent interest in this coin, which may increase its value at auction.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 250 to 300 euros, considering that the condition is 70 and there have been recent sales in that range. This also takes into account the interest in the coin and the relatively low starting price.
