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

2. Auction History: By looking at previous hammer prices for coins with similar conditions (95 and 100), we can see that the hammer prices have varied. For example:
- In a 2020 auction, a coin with a condition of 95 was sold for 65 euros.
- In another auction, a coin with a condition of 100 was sold for 220 euros.

3. Average Hammer Price: The average hammer price for this coin is 41.27 euros, providing a reference point.

4. Starting Price and Average Starting Price: The starting price is 25 euros, and the average starting price is 25.97 euros. This suggests that the market expects the coin to sell for a price higher than the starting price.

5. Recent Trends: In the most recent auctions, hammer prices have shown an increase, which could indicate a rising trend in interest for this coin.

Taking all these factors into account, an estimated maximum purchase price for the coin could be in the range of 70 to 100 euros, considering its good condition and the hammer price history of similar coins. A price of 85 euros could be a reasonable target, as it falls in the middle of this range and reflects both the quality of the coin and market trends.
