Given that the coin has a condition of 75 (MBC) and has not been auctioned or sold in the past, the starting price is 75 euros.
Without historical sales data for this reference, it is difficult to establish a maximum estimated purchase price. However, considering that the starting price is 75 euros and that the condition is good (MBC), you could consider a maximum estimated purchase price that could be in the range of 1.5 to 2 times the starting price, depending on collector interest and demand at the auction.
Therefore, a maximum estimated purchase price could be between 100 and 150 euros. This is just an estimate, and the actual price may vary according to the dynamics of the auction.
