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

1. 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 in lower conditions.

2. Starting price and previous prices: The current starting price is 3000 euros. In previous auctions, we have seen hammer prices that vary, but there are examples of hammer prices exceeding 3000 euros, especially for coins in similar conditions.

3. Price trends: The average hammer price in previous auctions is 2246.46 euros, but there are several cases where the hammer price has been significantly higher, especially for coins with a condition rating of 95.

4. Auction history: The coin has been auctioned 35 times, with a 74% sell-through rate (26 out of 35). This suggests that there is consistent interest in this coin, which may influence the price.

5. Recent hammer prices: In the most recent auctions, hammer prices have been competitive, with examples reaching up to 6250 euros in a 2022 auction.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 4000 to 5000 euros. This is based on the good condition of the coin, the demonstrated interest in previous auctions, and the potential for collectors to be willing to pay more for a coin in such good condition.
