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. Additionally, the coin's condition is rated at 80 (MBC+), which is positive but does not reach the highest level of preservation.

Considering that the starting price this time is 1300 euros and the average final auction price in previous auctions was 2100 euros, we could estimate a maximum purchase price around 2000-2200 euros. However, keep in mind that the final price will depend on the demand at the auction and other potential buyers interested in the coin.
