Given that the coin has a grade of 95 (S/C-), which is a very high grade, and considering that this is the first time it is being auctioned, the starting price is set at 1200 euros.

In general, coins in similar conditions tend to reach hammer prices that can exceed the starting price, especially if there is interest in the auction. Without historical sales data for this specific coin, it is difficult to make an accurate estimate, but we can consider that, in the case of high-grade coins, the hammer price can be between 1.5 and 2 times the starting price, depending on demand.

Therefore, an estimated maximum purchase price could be in the range of 1800 to 2400 euros. However, since the starting price is 1200 euros, a more conservative hammer price could be around 1800 euros, assuming there is interest in the auction.
