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

1. Coin Condition: The coin to be auctioned has a condition rating of 95 (EBC+), indicating that it is in very good condition. 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 similar conditions (95 and 100), we can see that the auction prices have varied. For example, in previous auctions, coins with a condition of 95 have reached hammer prices of up to 300 euros.

3. Average Hammer Price: The average hammer price for this coin is 101.76 euros, which provides a basis for estimating the maximum price.

4. Auction Trends: The coin has been auctioned 52 times, of which 44 have been successful sales. This indicates a consistent interest in the coin, which may increase its value in the current auction.

5. Starting Price: The starting price is 60 euros, which is relatively low compared to previous hammer prices.

Taking all these factors into account, an estimated maximum purchase price for the coin could be between 250 and 300 euros, given that there have been examples of similar coins reaching those prices in the past and the condition of this coin is high. However, the final price will depend on the competition in the auction and the interest of other bidders.
