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

1. Coin Condition: The coin has a condition rating of 75 (VF), indicating that it is in quite good shape. This generally translates to a higher price compared to coins in lower condition.

2. Price History:
- The average hammer price for this coin in the past is 88.42 euros.
- In previous auctions, hammer prices have varied, but there are examples of sales reaching up to 240 euros in similar or better conditions.

3. Starting Price: The current starting price is 60 euros, which is a good starting point, but given the price history, it is likely that the final hammer price will be significantly higher.

4. Recent Trends: In the most recent auctions, hammer prices have shown an increase, especially for coins in good condition. For example, in a recent auction, a coin with similar condition sold for 170 euros.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 120 to 150 euros. This is based on the hammer price history and the coin's condition, suggesting that it could reach a price above average in a competitive auction.
