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

1. Condition: The coin has a condition of 95 (EF+), which indicates that it is in very good shape. This generally increases its value compared to coins with lower conditions.

2. Auction history: By looking at previous hammer prices for coins with similar conditions (95 and 100), we can see that the hammer prices have varied. For example:
- In 2020, a coin with a condition of 95 was auctioned for 30 euros.
- In 2020, another coin with a condition of 100 was auctioned for 110 euros.
- In 2022, a coin with a condition of 90 was auctioned for 45 euros.

3. Average hammer price: The average hammer price for this coin is 38.25 euros, which gives us a reference for what buyers are willing to pay.

4. Estimated price: In previous auctions, the estimated price for similar coins has ranged between 20 and 125 euros, depending on the condition and demand.

Given that the coin is in good condition (EF+) and considering the history of hammer prices, an estimated maximum purchase price could be set in a range between 70 and 110 euros. This is based on the fact that coins in similar conditions have reached hammer prices in that range.

Therefore, a reasonable estimated maximum purchase price for this coin could be 100 euros.
