2. Auction History:
- The average hammer price for coins with a similar condition (70) in the past has been 55 euros (in the auction of 2020-12-15).
- In other auctions, hammer prices have varied, but the range seems to be between 20 and 120 euros, depending on the condition and demand.

3. Starting Price and Average Hammer Price:
- The current starting price is 40 euros, which is slightly higher than the average starting price of 30.7 euros.
- The average hammer price is 38.9 euros, suggesting that buyers are willing to pay a bit more than the starting price in general.

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