Given that the coin has a grade of 95 (S/C-), indicating very high quality, and considering that it is being auctioned for the first time, the starting price is set at 1800 euros.

In previous auctions, the average hammer price is not available, suggesting that there are no historical data that could influence the estimation. However, since the grade is high and the starting price is reasonable, a maximum purchase price can be estimated.

Taking these factors into account, an estimated maximum purchase price could range between 2,200 and 2,500 euros, depending on the demand at the auction and the interest of collectors.
