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

1. Current Condition: The coin has a condition rating of 70 (VF-), indicating that it is in acceptable shape, but not among the best qualities. This can influence the price, as coins in better condition tend to fetch higher prices.

2. Auction History:
- The average hammer price for this coin in the past is 94.18 euros.
- In previous auctions, we have seen hammer prices that varied significantly, ranging from 42 euros to 440 euros, depending on the condition and other factors.

3. Starting Price and Average Starting Price:
- The current starting price is 60 euros, which is slightly higher than the average starting price of 58.28 euros. This suggests that the seller has expectations of a higher price.

4. Recent Trends: In recent auctions, hammer prices have exceeded 100 euros, even reaching up to 290 euros in a previous auction.

5. Demand and Supply: Since there are no scheduled auctions in the coming days, this could increase competition among bidders interested in this coin.

Taking all these factors into account, an estimated maximum purchase price could be around 120-150 euros. This is based on the auction price history, current condition, and price trends in recent auctions. However, it is important to remember that the final price may vary depending on the competition in the auction and the interest of collectors.
