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 80 (MS+), indicating that it is in relatively good shape. This generally translates to a higher value compared to coins with lower conditions.

2. Previous Prices: By looking at previous auction prices for coins with similar conditions, we can see that the hammer price has varied. For example:
- In previous auctions, coins with conditions ranging from 70 to 75 have reached hammer prices between 110 and 200 euros.
- The coin with a condition of 95 was sold for 330 euros, indicating that better condition can significantly increase the price.

3. Starting Price and Average Hammer Price: The current starting price is 130 euros, and the average hammer price for this coin is 141 euros. This suggests that the market is willing to pay a bit more than the starting price.

4. Auction Trends: The coin has been auctioned 25 times, with a sell-through rate of 96% (24 out of 25). This indicates consistent demand.

5. Previous Estimates: The estimated price for the current auction is 180 euros, which can also serve as an indicator of what buyers are willing to pay.

Based on these factors, an estimated maximum purchase price could be in the range of 160 to 200 euros, considering that the condition is good and there is a trend of increasing prices in recent auctions. A price of 180 euros could be a reasonable target, given that it is the estimated price and aligns with previous hammer prices for similar conditions.
