Based on the data provided, we can observe that the coin in question has performed well in previous auctions, with final prices that have significantly exceeded the starting and estimated prices. Additionally, the coin's condition is rated at 70 (VF+), which is positive but does not reach the highest level of preservation.

Taking into account the previous prices of this coin and its auction history, as well as the fact that it has been auctioned eight times before and has been sold in all of them, we could estimate a maximum purchase price around 100-110 euros. Since the final price in the last auction was 120 euros, this range seems reasonable to ensure a successful acquisition of the coin in question.
