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

1. Current Condition: The coin is in a condition of 70 (VF-). This indicates that it is in relatively good shape, but not among the best qualities (UNC).

2. Auction History:
- The average hammer price for this coin is 47.27 euros.
- In previous auctions, hammer prices have varied significantly, with some reaching up to 140 euros in higher condition grades (such as 100 or 95).
- The last auction for this coin showed a starting price of 30 euros, with an estimated price of 50 euros.

3. Price Trends:
- The coin has been auctioned 119 times, of which it has sold 101 times. This indicates good demand.
- The average starting price is 31 euros, suggesting that starting prices have been in an accessible range.

4. Comparison with Previous Prices:
- In previous auctions, coins with a similar condition have had hammer prices ranging from 20 to 100 euros, depending on demand and quality.

Based on these factors, an estimated maximum purchase price for the coin in its current state (70 VF-) could be in the range of 60 to 80 euros. This is based on the auction price history and the current condition, considering that interest in the coin may influence the final price.
