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 condition. This generally translates to a higher price compared to coins of lower quality.

2. Auction History:
- The average hammer price for similar coins has been 69.25 euros.
- In previous auctions, coins with a similar condition (95) have reached hammer prices that varied, but some have exceeded 100 euros, as seen in the 2023 auctions.

3. Starting Price and Previous Prices:
- The current starting price is 45 euros, which is reasonable given the history of starting and hammer prices.
- In previous auctions, the highest hammer price for coins with a condition of 95 has been up to 240 euros.

4. Recent Trends: Recent auctions show an increase in hammer prices, especially for coins in high condition.

Based on these factors, an estimated maximum purchase price for this coin could be between 120 and 150 euros, considering that the market may be willing to pay more for a coin in such good condition and with a favorable auction history.
