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

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

2. Previous Auction Prices: By looking at the hammer prices of coins with a similar condition (95), we can see that they have reached hammer prices that vary considerably. For example:
- In previous auctions, coins with a condition of 95 have sold for prices ranging from 150 to 440 euros.

3. Starting Price and Average Hammer Price: The current starting price is 125 euros, and the average hammer price for this coin in the past has been 56.41 euros. However, given the high condition, it is likely that the actual hammer price will be significantly higher.

4. Recent Trends: In the most recent auctions, hammer prices for coins of similar condition have been higher, suggesting that interest and value for these coins are increasing.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 250 to 300 euros, considering that the condition is high and there is a history of hammer prices that supports this estimate.
