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. Auction History:
- The average hammer price for this coin is 214.14 euros.
- In the past, hammer prices have varied significantly, ranging from 40 euros to over 1900 euros, depending on the condition and demand at the time of the auction.

3. Recent Auction Prices:
- In recent auctions, hammer prices have been in the range of 70 to 245 euros for coins with similar conditions (for example, 95 and 80).

4. Starting Price: The starting price is 175 euros, which may influence the final price, as hammer prices are often higher than the starting price.

Taking these factors into account, an estimated maximum purchase price for this coin could be in the range of 250 to 300 euros, given its condition and the history of hammer prices. This is based on the trend that coins in similar conditions have reached hammer prices in that range in the past.
