Based on the data provided, we can observe that the coin in question has performed well in previous auctions, with final prices consistently exceeding the starting and estimated prices. Additionally, the coin's condition is at a high level (85 - ebc-).

Considering that the historical average auction price is 58.74 euros and the coin's condition is high, we could estimate a maximum purchase price around 70-80 euros. Given that the coin will be auctioned in the coming days and has had a good performance in previous auctions, it is possible that the final auction price may exceed this estimate.

It is important to note that the final auction price will depend on various factors, such as demand at that specific time, competition from other bidders, and interest in the coin in question.
