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 70 (VF-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Auction History:
- The average hammer price for similar coins in the past is 39.8 euros.
- The coin has been auctioned 72 times, of which it has sold 61 times, indicating good demand.
- Previous hammer prices for coins with a similar condition (70) have varied, but there are examples of auctions reaching up to 95 euros (in the case of a condition of 75).

3. Starting Price and Estimated Price:
- The starting price is 30 euros, and the estimated price is 50 euros. This suggests that the seller expects considerable interest in the coin.

4. Recent Trends: In the most recent auctions, hammer prices for coins with a condition of 70 have been in the range of 20 to 30 euros, but there are also examples of higher hammer prices.

Based on these factors, an estimated maximum purchase price could be in the range of 50 to 70 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate.

Therefore, a reasonable maximum purchase price could be 70 euros.

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

1. Current Condition: The coin has a condition rating of 75 (MBC), indicating that it is in quite good shape. This is important because coins in better condition tend to fetch higher prices.

2. Auction History:
- The average hammer price for similar coins has been 125.9 euros.
- In previous auctions, we have seen hammer prices that varied, but some have reached up to 320 euros under similar conditions (such as in the auction on 2021-06-22).

3. Starting Price and Average Starting Price:
- The current starting price is 40 euros, which is relatively low compared to the average hammer price.
- The average starting price has been 70 euros, suggesting that the market is willing to pay more than the starting price.

4. Sales Trends: The coin has been sold in 21 out of the last 22 auctions, indicating good demand.

5. Comparison with Previous Prices:
- In previous auctions, coins with a similar condition have reached hammer prices of 95 to 150 euros, and in some exceptional cases, up to 220 euros.

Based on these factors, an estimated maximum purchase price for this coin could be between 150 and 200 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate. However, given the starting price of 40 euros, it could be a good opportunity to acquire it at a lower price if the competition in the auction is not high.

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

2. Starting Price and Average Hammer Price: The current starting price is 60 euros, and the average hammer price in previous auctions is 79.71 euros. This suggests that, on average, similar coins have reached hammer prices above the starting price.

3. Price History: By looking at previous hammer prices for coins with similar conditions (around 80), we can see that they have reached hammer prices that vary, but some have reached 120 euros or more under similar conditions.

4. Sales Trends: The coin has been auctioned 68 times, of which it has sold 62 times. This indicates good demand and consistent interest in the coin, which can influence the price.

5. Comparison with Previous Prices: In previous auctions, coins with conditions of 80 have had hammer prices ranging from 75 to 120 euros.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 90 to 120 euros, considering that the condition is good and that interest in the coin appears to be solid. A price of 100 euros could be a reasonable starting point for an offer, as it falls in the middle of this range and reflects both the condition and the price history.
