To estimate a maximum purchase price for the coin in question, we will 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. Current Starting Price and Previous Prices: The current starting price is 600 euros. The average hammer price in previous auctions is 364.14 euros, suggesting that the current starting price is quite high compared to the historical average.

3. Price Trends: By observing the hammer prices of coins with similar conditions (95), we can see that they have reached hammer prices of up to 550 euros in recent auctions. However, there are also examples of coins that have sold for over 600 euros, especially if demand is high.

4. Sales History: The coin has been auctioned 41 times, of which 36 have been sold. This indicates a good sales rate, which may be an indicator of interest in the coin.

5. Comparison with Previous Prices: In previous auctions, coins with a condition of 95 have had hammer prices that vary, but some have reached up to 500-550 euros.

Taking all these factors into account, an estimated maximum purchase price could be between 600 and 700 euros, considering that interest in the coin may lead bidders to be willing to pay a bit more than the starting price. However, since the starting price is already 600 euros, a realistic hammer price could be closer to 650 euros, assuming that demand remains steady.
