To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Condition of the coin: The coin has a condition rating of 95 (EBC+), indicating that it is in very good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Previous auction prices: By observing the hammer prices of coins with similar conditions (around 90-95), we can see that they have reached hammer prices that vary considerably, but many have exceeded 100 euros.

3. Current starting price: The starting price is 125 euros, suggesting that the seller has expectations of a relatively high hammer price.

4. Price trends: In previous auctions, coins with similar conditions have had hammer prices ranging from 150 to 320 euros, depending on demand and other market factors.

5. Number of auctions and sales: The coin has been auctioned 117 times, of which 105 have been sold. This indicates a consistent interest in the coin, which may positively influence its price.

Taking all these factors into account, an estimated maximum purchase price for this coin could be between 200 and 250 euros. This range reflects both the good condition of the coin and the price trends observed in previous auctions.
