Given that the coin has a grade of 80 (MBC+), indicating good quality, and considering that this is the first time it is being auctioned, the starting price is set at 100 euros.
In this case, since there are no historical sales data for this coin, a maximum purchase price can be estimated based on the grade and the starting price.
Generally, coins in good condition can reach prices above the starting price, especially if there is interest in the auction. A reasonable estimate could be between 1.5 to 2 times the starting price, depending on the interest from collectors.
Therefore, an estimated maximum purchase price could be between 150 and 200 euros. However, since there are no sales records, it is difficult to be more precise. A conservative maximum price could be approximately 150 euros.
