Given that the coin has a conservation grade of 95 (S/C-), which is a very high grade, and considering that it is being auctioned for the first time, the starting price is set at 1500 euros.

In the collector's market, coins in high conservation conditions often reach prices that can be significantly higher than the starting price, especially if there is interest in the auction. However, since there are no historical sales data for this coin, it is difficult to make an accurate estimate.

Taking into account the conservation and the starting price, an estimated maximum purchase price could be in the range of 2000 to 2500 euros, depending on the interest of collectors and the competition in the auction.
