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

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

2. Current Starting Price and Previous Prices: The current starting price is 40 euros, and the average hammer price in previous auctions is 36.64 euros. However, in recent auctions, we have seen hammer prices reaching up to 95 euros.

3. Price Trends: By observing the hammer prices of coins with similar conditions (around 80-95), we can see that prices have fluctuated but have reached higher figures in the past. For example, in 2023, a coin with a condition of 95 was sold for 60 euros.

4. Demand and Supply: The coin has been auctioned 23 times, of which it has sold 22 times, indicating good demand. This can influence the hammer price.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 70 to 90 euros, considering that the condition is high and there are precedents for hammer prices in that range. A price of 80 euros could be a reasonable target, as it falls in the middle of that range and reflects the good condition of the coin.
