Based on the data provided, we can observe that the coin has had an average auction closing price of 38.9 euros in previous auctions. Additionally, the condition of the coin on this occasion is 70 (VF-).

Considering that the starting price in this auction is 60 euros and the condition is relatively good, we could estimate a maximum purchase price around 45-50 euros. This is because the average auction closing price in previous auctions has been 38.9 euros, so offering a little more than this value could be reasonable given the condition of the coin and the current starting price.
