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

1. Condition: The coin has a condition rating of 25 (BC), which indicates that it is not in the best shape. This generally reduces its value compared to coins in better condition.

2. Auction history:
- The average hammer price in previous auctions for coins with a similar condition (25) has been 45 euros.
- The average starting price has been 32.88 euros, indicating that starting prices are usually lower than hammer prices.

3. Price trends:
- In previous auctions, hammer prices have varied, but the range has been between 20 and 100 euros, depending on condition and other factors.

4. Current starting price: The starting price is 18 euros, which is relatively low and may attract more bidders.

Given that the coin's condition is 25 and considering the hammer price history, an estimated maximum purchase price could be around 45 euros, which is the average hammer price for coins in similar condition. However, since the starting price is low, some bidders may be willing to pay a bit more.

Therefore, a reasonable estimated maximum purchase price could be 45 to 50 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 current condition of the coin.

1. 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. Previous auction prices: By looking at the auction prices of coins with a similar condition (95), we can see that they have reached auction prices of up to 130 euros in recent auctions. For example:
- In 2024, a coin with a condition of 95 was auctioned for 130 euros.
- In 2024, another coin with a condition of 95 was auctioned for 95 euros.

3. Price trends: The average auction price for this coin is 34 euros, but this may be influenced by coins of lower condition. Given that the condition of this coin is high, it is reasonable to expect that the auction price will be above this average.

4. Starting price: The starting price is 20 euros, suggesting that the auctioneer expects moderate interest in the coin.

5. Estimation: Based on the condition, previous auction prices, and market context, an estimated maximum purchase price could be between 80 and 130 euros. This is because, although the highest recorded auction price was 130 euros, it is prudent to consider a more conservative range for the estimation.

Therefore, an estimated maximum purchase price for this coin could be 100 euros. This reflects a balance between the high condition and previous auction prices while maintaining a realistic perspective on market interest.

To estimate a maximum purchase price for the coin that will be auctioned, we will consider several factors:

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

2. Historical auction data:
- The average hammer price for coins of similar condition (EF) in the past has been approximately 98.9 euros.
- Coins with conditions of 90 and 95 have been auctioned, and the hammer prices have varied, but they have generally remained within a range that may indicate a higher hammer price for superior conditions.

3. Starting price and previous prices:
- The current starting price is 25 euros, which is significantly lower than the average hammer price.
- In previous auctions, coins with a condition of 90 have reached hammer prices ranging from 40 to 190 euros, depending on demand and other factors.

4. Auction trends:
- Since it has been auctioned 1295 times and sold 999 times, this indicates good demand for this coin.

Based on these factors, an estimated maximum purchase price for the coin in question could be in the range of 100 to 150 euros. This is based on the average hammer price and the condition of the coin, as well as the price trends from previous auctions.

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

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

2. Previous Auction Prices: By observing the auction prices of coins with a similar condition (80), we can see that they have reached auction prices that vary, but generally, auction prices for coins in MBC+ condition tend to be in a range of 40 to 110 euros, depending on demand and other factors.

3. Average Auction Price: The average auction price for this coin is 153.86 euros, suggesting that there is a higher selling potential, especially if demand is strong.

4. Auction Trends: The coin has been auctioned 101 times, with a high sales percentage (92 out of 101). This indicates a consistent interest in this coin, which can influence the price.

5. Starting Prices and Estimates: The starting price is 25 euros, and the average starting price is 62.11 euros. This suggests that the auction price could be significantly higher than the starting price.

Taking all these factors into account, an estimated maximum purchase price for this coin could be in the range of 150 to 200 euros. This is based on the condition, previous auction prices, and the general auction trend. However, the final price will depend on the competition in the auction and the demand at that specific moment.

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 70 (MBC-), indicating that it is in acceptable condition, but not among the best.

2. Auction History:

- 70 euros (2022-03-10)
- 50 euros (2023-02-16)
- 50 euros (2022-10-18)

3. Starting Price and Average Starting Price:
- The current starting price is 30 euros, and the average starting price in the past has been 38.42 euros.

4. Price Trends:
- In recent auctions, the hammer price has ranged from 50 to 95 euros for coins of similar condition.

Based on this data, an estimated maximum purchase price could be set in a range between 70 and 90 euros, considering that the average hammer price has been 76.12 euros and that the coin's condition is rated at 70.

Therefore, a reasonable estimated maximum purchase price could be 85 euros.

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