Given that the coin has a conservation grade of 95 (EBC+), which is a very good condition, and considering that this is the first time it is being auctioned, the starting price is set at 600 euros.

In previous auctions, the final price is not available, suggesting that there is no sales history that could influence the estimation. However, since the starting price is the same as the average starting price and there is no prior competition, it is reasonable to estimate that the final price could be in a range above the starting price, especially considering the high conservation grade.

Based on these factors, an estimated maximum purchase price could be in the range of 800 to 1,000 euros, depending on the demand at the auction and the interest from collectors.
