3. Starting Price and Previous Prices:
- The current starting price is 60 euros, which is reasonable given the hammer price history.
- In recent auctions, coins with a condition of 95 have had hammer prices ranging from 110 to 140 euros.

4. Market Trends: Given that there are 4 similar coins that will be auctioned in the coming days, this could influence competition and the final price.
