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 70 (VF-), indicating that it is in relatively good shape, but not of the highest quality (UNC).

2. Current Starting Price and Previous Prices: The current starting price is 50 euros, and the average starting price in previous auctions is 100.45 euros. This suggests that the current starting price is quite low compared to the historical average.

3. Previous Hammer Prices: The average hammer price in previous auctions is 153.33 euros. This indicates that, in general, buyers are willing to pay more than the starting price.

4. Sales Trends: The coin has been auctioned 10 times, of which it has sold 9 times. This suggests that there is consistent interest in the coin, which may increase its value.

5. Recent Hammer Prices: The hammer prices in recent auctions (for example, 55 euros in 2022) are lower than the average, which could indicate a downward trend in interest or value for the coin.

Given all this, an estimated maximum purchase price could be calculated by considering the average hammer price and adjusting it for the current condition.

If we take the average hammer price of 153.33 euros and adjust it for the condition of 70 (VF-), we could estimate that a reasonable maximum price might be in the range of 100 to 120 euros, given that the condition is not the best.

Therefore, an estimated maximum purchase price could be 120 euros.

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 75 (MBC), which indicates that it is in fairly good shape, but not the best possible condition.

2. Auction History:
- The average hammer price for similar coins in the past is 83 euros.
- The condition of the coins auctioned in the past varied, but there are examples of coins with similar conditions (70-80) that have sold for prices ranging from 25 to 380 euros, depending on the condition and demand.

3. Starting Price and Average Starting Price:
- The current starting price is 25 euros, which is relatively low compared to the average hammer price of 83 euros.
- The average starting price of 45.22 euros also suggests that there is potential for an increase in the hammer price.

4. Recent Trends: In the most recent auctions, hammer prices have varied, but there is a pattern that coins with conditions of 70-80 have reached hammer prices around 40-70 euros.

Based on these factors, an estimated maximum purchase price for this coin could be around 70-80 euros, as this price reflects its condition and the sales history of similar coins. However, it is important to keep in mind that the final price may vary depending on the competition in the auction and the specific demand at that time.

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

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

For example, in past auctions, coins with a condition of 80 have reached hammer prices of up to 63 euros, while others with a condition of 85 have gone up to 140 euros.

4. Starting Price and Average Starting Price: The current starting price is 40 euros, and the average starting price is 80.76 euros. This suggests that the market is willing to pay more than the starting price, especially for coins in good condition.

5. Recent Trends: Recent trends in auctions show that coins in similar conditions have seen an increase in hammer prices, which could indicate growing interest in this type of coin.

Based on these factors, an estimated maximum purchase price for the coin in question could be between 120 and 150 euros, considering that the condition is good and that interest in such coins seems to be on the rise. However, it is important to keep in mind that the final price will depend on the competition in the auction and the specific demand at the time.
