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 of 80 (MBC+). This is an important factor, as coins in better condition tend to reach higher prices.

2. Historical Prices: By looking at previous auction prices for coins with similar conditions (80 and 90), we can see that:
- In 2020, a coin with a condition of 80 was auctioned for 120 euros.
- In 2018, another coin with a condition of 80 sold for 55 euros.
- In 2022, a coin with a condition of 80 sold for 75 euros.

3. Average Auction Price: The average auction price for this reference is 172.45 euros, indicating that, in general, coins of this reference tend to reach higher prices.

4. Starting Price: The starting price is 25 euros, suggesting that there is considerable room for the final price to be higher.

5. Auction Trends: The coin has been auctioned 14 times, of which 12 have sold. This indicates good demand and sustained interest in this reference.

Based on these factors, an estimated maximum purchase price could be in the range of 120 to 150 euros, considering that the condition is 80 and there are precedents for sales in that range. However, given the average auction price of 172.45 euros, it is reasonable to consider that if the auction generates interest, the price could even exceed 150 euros.

Therefore, an estimated maximum purchase price could be 150 euros.

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 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 average hammer price for similar coins is 98.85 euros.
- In the past, hammer prices have varied significantly, ranging from 42 euros to 600 euros, although the latter seems to be an outlier.
- Most hammer prices for coins with similar condition (80) have been in the range of 40 to 130 euros.

3. Starting Price: The current starting price is 35 euros, which is relatively low compared to the average hammer price.

4. Sales Trends: The coin has been auctioned 24 times, of which 18 have sold. This indicates good demand and sustained interest in the coin.

5. Previous Prices: In previous auctions, coins with a condition of 80 have reached hammer prices of up to 130 euros.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 100 to 130 euros, considering that the condition is good and that interest in the coin appears to be solid. Therefore, a reasonable maximum purchase price could be 120 euros.

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

1. Condition: The coin has a condition rating of 80 (MS+), 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 average hammer price for this coin is 61.36 euros.

3. Starting Price: The current starting price is 50 euros, which is a good starting point.

4. Recent Trends: In the most recent auctions, hammer prices have been in the range of 40 to 65 euros for coins of similar condition.

Based on these factors, an estimated maximum purchase price could be around 80 euros. This is because, although the average hammer price is 61.36 euros, the good condition of the coin and the history of higher prices suggest that there could be enough interest to reach a higher price. However, it is important to keep in mind that the market can be variable, and collector interest at the time of the auction will also influence the final price.

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

1. Condition: The coin has a condition rating of 85 (ebc-), which indicates that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction history:
- The average hammer price in previous auctions is 61.95 euros.

3. Sales trends: The coin has been auctioned 12 times, of which it has sold 10 times. This indicates good demand and consistent interest in the coin.

4. Current starting price: The starting price is 65 euros, which is slightly higher than the average starting price in the past, but may be reasonable given the condition.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 80 to 100 euros. This is based on the hammer price history and the condition of the coin. A price of 90 euros could be a reasonable target, considering it is slightly higher than the previous average hammer price and reflects the good condition of the coin.
