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

1. Current Condition: The coin has a condition rating of 75 (MBC), indicating that it is in acceptable shape, but not in exceptional condition. This may influence the price, as coins in better condition tend to fetch higher prices.

2. Auction History:
- The average hammer price in previous auctions is 254.67 euros, suggesting that, in general, coins of this reference tend to sell close to this price.
- The most recent auction with a similar condition (75) had a hammer price of 351 euros, indicating that there is a market willing to pay more for coins in this state.

3. Starting Price: The current starting price is 250 euros, which is a good starting point. However, since the average hammer price is higher, it is reasonable to consider that the final price could be higher.

4. Sales Trends: Of the 12 times it has been auctioned, it has sold on 9 occasions, indicating good demand. Additionally, there have been no recent auctions scheduled, which could increase interest in this specific auction.

5. Comparison with Previous Prices: Previous hammer prices vary, but there are examples of auctions exceeding 600 euros in better conditions. This suggests that, although the current condition is 75, there is potential for a higher hammer price.

Taking all these factors into account, an estimated maximum purchase price could be around 350-400 euros. This is based on market interest, price history, and the current condition of the coin.

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

1. Current Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The coin has been auctioned 8 times and has sold on all occasions, indicating consistent demand.
- The average hammer price in the past is 320.63 euros, suggesting that buyers are willing to pay above the starting price in most cases.
- In the most recent auction (2022), the coin sold for 550 euros, indicating that, despite variability, there is potential for high prices.

3. Starting Price and Average Hammer Price:
- The current starting price is 250 euros, which is higher than the average starting price of 175 euros in previous auctions. This may indicate that the seller is confident that the coin will reach a higher price.
- Given that the average hammer price is 320.63 euros, this can serve as a benchmark for the estimated price.

4. Price Trends:
- Observing previous hammer prices, there is a trend for hammer prices to exceed the starting price, especially for coins in good condition.

Based on these factors, an estimated maximum purchase price could be in the range of 400 to 600 euros, considering that the last auction reached 550 euros and that the coin's condition is good. A price of 500 euros could be a reasonable target, as it falls in the middle of this range and reflects both demand and the quality of the coin.
