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

1. Condition of the coin: 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 with lower conditions.

2. Auction history:
- The average hammer price for this coin in the past is 98.05 euros.
- It has been auctioned 29 times, of which 24 have been successful sales, indicating good demand.
- In previous auctions, hammer prices have varied, but there are examples of auctions that have reached up to 260 euros (in the case of a condition rating of 95).

3. Starting price and estimates:
- The current starting price is 110 euros, suggesting that the seller has expectations of a higher hammer price.
- The average starting price in the past has been 45.79 euros, but this may not be representative of the current situation due to the high condition of this coin.

4. Recent trends: In the most recent auctions, hammer prices have shown a trend of being higher, especially for coins in good condition.

Based on these factors, an estimated maximum purchase price could be in the range of 150 to 200 euros, considering the good condition and the history of hammer prices. However, since the starting price is 110 euros, it is likely that the hammer price will not significantly exceed this value unless there is active competition among bidders.

Therefore, a reasonable maximum purchase price could be 180 euros.
