Given that the coin has a conservation 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 750 euros.

In the collectibles market, coins in high conservation condition often reach prices above the starting price, especially if there is no prior competition in auctions.

Since there are no historical sales data for this coin, it is difficult to establish an exact price, but based on the conservation and the starting price, an estimated maximum purchase price could be in the range of 1,200 to 1,500 euros, depending on the interest of collectors and the demand at the auction.

Therefore, an estimated maximum purchase price could be approximately 1,300 euros.
