Based on the data provided, we can observe that the coin has performed well in previous auctions, with final prices exceeding the starting and estimated prices by a significant margin. The coin's condition is rated as high, with a score of 85 (ebc-).

The average final auction price of the coin in previous auctions has been 130.02 euros, while the average starting price has been 49.29 euros. However, in specific auctions, the final price has reached much higher values, such as 265 euros in a December 2020 auction.

Considering that the coin will be auctioned in the coming days and taking into account its history of successful auctions, its condition, and the upward trend in final prices, we could estimate a maximum purchase price of around 300 euros. This is considering that the highest recorded final price was 265 euros, but acknowledging the possibility that this time the price could exceed that value due to demand and the quality of the coin.
