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

1. Coin Condition: The coin has a condition rating of 95 (S/C-), indicating that it is in very good shape. This generally increases its value compared to coins with lower conditions.

Given all this, an estimated maximum purchase price could be around 60-80 euros, considering that the condition is high and that interest in the coin appears to be strong. This also takes into account that in previous auctions, higher hammer prices have been reached, especially for coins of similar condition.

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

1. Current Condition: The coin has a condition rating of 30 (BC+). This indicates that it is not in the best condition, which generally affects its value.
