Given that the coin has a grade of 95 (EBC+), which is a very good condition, and considering that the starting price is 2500 euros, we can estimate a maximum purchase price.

In previous auctions, the final price tends to be higher than the starting price, especially for coins in good condition. However, since there is no historical sales data for this particular coin, it is difficult to make an accurate estimation.

Generally, in the case of coins in similar conditions, the final price can range from 1.5 to 2 times the starting price, depending on the demand and rarity of the coin.

Therefore, an estimated maximum purchase price could be between 3750 and 5000 euros. However, since there are no sales records, it is advisable to pay attention to the dynamics of the auction and the competition from other bidders.
