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 increases its value compared to coins with lower conditions.

2. Auction History:
- The average hammer price for this coin in the past is 71.83 euros.
- In previous auctions, the coin has reached hammer prices of up to 260 euros (in an auction in 2017 with a starting price of 90 euros).
- The last auction with a known hammer price was 25 euros, but this refers to a coin in lower condition (70).

3. Starting Price and Estimates:
- The current starting price is 60 euros, which is higher than the average starting price of 35.81 euros, suggesting that there is an expectation for the coin to sell at a higher price.
- The estimated price of 150 euros in previous auctions also suggests that there is significant potential for a higher hammer price.

Taking these factors into account, an estimated maximum purchase price could be in the range of 150 to 200 euros, given that the condition is high and there are precedents for hammer prices exceeding 200 euros. However, to be conservative and considering the starting price, a reasonable maximum purchase price could be approximately 180 euros.
