To estimate a maximum purchase price for the coin that will be auctioned, we can consider several factors based on the provided data:

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. Starting Price: The starting price is 60 euros. This is the baseline for the auction.

3. Price History: By looking at previous auction prices for coins with a similar condition (95), we can see that they have reached hammer prices of up to 90 euros in recent auctions. For example, in past auctions, coins with a condition of 95 have had hammer prices of 60, 65, 80, and 90 euros.

4. Average Hammer Price: The average hammer price for this coin is 46.83 euros, but given the high condition, we can expect the hammer price to be above this average.

5. Recent Trends: In the most recent auctions, hammer prices for coins of similar condition have shown an increase, suggesting that interest in these coins is growing.

Based on these factors, an estimated maximum purchase price for this coin could be between 80 and 100 euros. This is due to the high condition and the hammer price history for similar coins. Therefore, a reasonable maximum purchase price could be 90 euros.
