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

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

2. Auction History: By observing the hammer prices of coins with similar conditions (95 and 90), we can see that the hammer prices have varied, but generally, coins in EBC+ condition have reached hammer prices ranging from 60 to 140 euros in previous auctions.

3. Average Hammer Price: The average hammer price for this particular coin is 38.74 euros, but given the high condition, we can expect the actual hammer price to be significantly higher.

4. Starting Prices and Previous Estimates: The current starting price is 30 euros, and the average starting price in the past has been 30.48 euros. However, the estimated price in previous auctions for coins of similar condition has been higher.

5. Recent Trends: In the most recent auctions, we have seen hammer prices reaching up to 140 euros for coins in condition 100, suggesting that there is an active market willing to pay higher prices for well-preserved coins.

Taking all these factors into account, an estimated maximum purchase price for this coin, considering its high condition and the history of hammer prices, could be around 100-120 euros. This reflects a balance between the condition, price history, and market trend.
