Therefore, a reasonable maximum purchase price could be 30 euros.

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

1. Current Condition: The coin has a condition of 85 (ebc-), which indicates that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Previous Prices: By looking at previous auction prices for coins with similar conditions, we can see that:
- In recent auctions, coins with a condition of 85 have reached hammer prices of up to 20 euros.
- In earlier auctions, coins with conditions of 90 and 95 have reached hammer prices of 40 to 80 euros.

3. Average Hammer Price: The average hammer price for this particular coin is 83.43 euros, suggesting that, in general, coins of this reference tend to sell for relatively high prices.
