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 (VF), indicating that it is in fairly good condition.

2. Previous Auction Prices: The average auction price for this coin is 187.33 euros. This suggests that, in general, buyers are willing to pay significantly more than the starting price.

3. Auction Prices for Similar Conditions: By observing the auction prices of coins with similar conditions (75 and 80), we can see that they have reached auction prices of up to 260 euros in recent auctions.

4. Auction Trends: The coin has been auctioned 51 times, of which 44 have been sold. This indicates good demand and consistent interest in the coin.

5. Starting Price: The starting price is 80 euros, which is relatively low compared to the average auction price.

Based on these factors, an estimated maximum purchase price could be in the range of 200 to 260 euros, considering that the highest auction price in recent sales for similar conditions has been 260 euros.

Therefore, a reasonable maximum purchase price could be 250 euros. This allows for some competition in the auction and aligns with previous auction prices.

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 not in the best condition, but it is also not the worst.

2. Current Starting Price and Previous Prices: The current starting price is 70 euros. In previous auctions, the average hammer price has been 162.08 euros, suggesting there is significant potential for an increase in the selling price.

3. Sales History: The coin has been auctioned 82 times, of which 77 have been successful sales. This indicates good demand and consistent interest in the coin.

4. Previous Hammer Prices: By observing the hammer prices of coins with similar conditions (around 70), we can see that they have reached hammer prices that vary, but some have reached 130-140 euros in similar conditions.

5. Recent Trends: In the most recent auctions, the hammer prices have shown a range that may indicate an increase in interest or value of the coin.

Based on these factors, an estimated maximum purchase price could be in the range of 130 to 160 euros, considering that the coin has a history of hammer prices that align with this range and that condition is an important factor to take into account.

Therefore, a reasonable estimated maximum purchase price could be 150 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 25 (BC), indicating that it is in a fairly deteriorated state. This generally reduces its value compared to coins in better condition.

2. Auction History:
- The average hammer price for similar coins in better condition (for example, with condition ratings of 70 to 95) has been significantly higher. For instance, in previous auctions, coins with condition ratings of 70 and 80 have reached hammer prices of up to 170 euros.
- The last auction of a coin with a similar condition (25) had a hammer price of 30 euros.

3. Starting Price and Average Hammer Price:
- The current starting price is 50 euros, which is lower than the average hammer price of 211.82 euros for coins in better condition. However, given the low condition, it is likely that the actual hammer price will be below this average.

4. Sales Trends: The coin has been auctioned 31 times, of which it has sold 28 times. This indicates a consistent interest in the coin, although the condition may affect demand.

Based on these factors, an estimated maximum purchase price for this coin, considering its condition and price history, could be between 30 and 50 euros. Since the starting price is 50 euros, it is likely that the hammer price will not exceed 50 euros, especially considering that in previous auctions, coins in similar conditions have had hammer prices around 30 euros.

Therefore, a reasonable estimated maximum purchase price could be 40 euros.

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

2. Average hammer price in the past: 140 euros. This indicates that, in general, coins of this reference tend to sell for a price higher than the starting price.
3. Condition: The coin has a condition of 70 (VF-), which suggests that it is in relatively good shape, although it is not of the highest quality (UNC).
4. Auction history: It has been auctioned once and sold on that occasion, indicating that there is interest in the coin.

Given that the average hammer price is significantly higher than the starting price, and considering the condition of the coin, an estimated maximum purchase price could be positioned between the average hammer price and a little more, since the condition is good but not excellent.

Therefore, an estimated maximum purchase price could be around 160-180 euros. This is based on the interest that the coin may generate and its state of preservation.

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