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 (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 in the past has been 45 euros.

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

1. Starting price: 50 euros.
2. Average hammer price in the past: 110 euros.
3. Current condition: 70 (MBC-), which indicates a fairly good condition, although not the best.
4. Auction history: It has been auctioned 2 times in the past, with 1 sale and 1 no sale. This suggests that there is interest, but also that there may be limitations in demand.
5. Average starting price: 50 euros, indicating that the starting price has remained constant.

Given that the average hammer price in the past was 110 euros and considering that the current condition is 70, which is lower than the condition of the coins that reached that price, we could estimate a maximum purchase price that is lower than the previous average hammer price.

Taking all these factors into account, an estimated maximum purchase price could be between 80 and 100 euros. This reflects an interest in the coin, but also takes into account the condition and auction history.

Therefore, a reasonable estimated maximum purchase price would be 90 euros.

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. Auction History:
- The average starting price for similar coins is 32.52 euros, and the average final price is 36.5 euros.
- In the past, coins with similar conditions (75-90) have been auctioned at prices that varied considerably, but some relevant examples are:
- A coin with a condition of 75 sold for 20 euros and another for 18 euros.
- A coin with a condition of 90 sold for 80 euros.

3. Sales Trends: Out of the 19 times this coin has been auctioned, it has sold 9 times, indicating moderate interest in the coin. However, the fact that it did not sell 10 times may suggest that the starting price is an important factor.

4. Current Starting Price: The starting price is 30 euros, which is slightly below the average starting price of 32.52 euros.

Based on these factors, an estimated maximum purchase price could be in the range of 40 to 50 euros. This is because, given the condition and price history, it is reasonable to expect that a buyer would be willing to pay a little more than the starting price, especially considering that the coin is in relatively good condition.

Therefore, an estimated maximum purchase price could be 45 euros.

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

1. Coin Condition: The coin to be auctioned has a condition of 75 (MBC), which indicates that it is in relatively good shape, but not among the best qualities.

2. Previous Prices: By looking at the hammer prices from previous auctions for coins of similar condition (75 and 70), we can see that:
- In 2019, a coin with a condition of 75 was sold for 110 euros.
- In 2024, a coin with a condition of 70 was sold for 210 euros.
- In 2024, another coin with a condition of 85 was sold for 2400 euros, but this is an exceptional case and cannot be considered representative for a condition of 75.

3. Average Hammer Price: The average hammer price for coins of this reference is 649.6 euros, but this includes coins of different conditions, so it is not directly applicable to the condition of 75.

4. Starting Price: The starting price of 40 euros is quite low compared to previous hammer prices, suggesting there is potential for a significant increase in the final price.

5. Auction Trends: Since the coin has been sold on all previous occasions and there have been no failed attempts at sale, this indicates a consistent interest in the coin.

Based on these factors, an estimated maximum purchase price for the coin with a condition of 75 could be in the range of 150 to 250 euros, considering that the highest hammer price for a similar condition was 210 euros and that the starting price is low.

Therefore, a reasonable estimated maximum purchase price could be 200 euros.

To estimate a maximum purchase price for the coin in question, let's consider the following factors:

1. Current Condition: The coin has a condition of 75 (MBC), indicating that it is in fairly good shape, although not the best possible condition.

2. Auction History:
- It has been auctioned 3 times in the past and has sold on all occasions.
- The average hammer price in previous auctions is 34 euros, with an estimated price of 30 euros in one of the auctions.

3. Starting Price: The starting price is 10 euros, suggesting that there is considerable room for the hammer price to be higher.

Given that the current condition is lower than that of the auction where it sold for 34 euros, and considering that the average hammer price is 34 euros, we could estimate that the maximum purchase price could be in a similar range, but adjusted for condition.

A reasonable approach would be to consider a discount on the previous hammer price due to the lower condition. We could estimate a maximum purchase price around 25-30 euros, taking into account that condition is an important factor and that the previous hammer price was 34 euros.

Therefore, an estimated maximum purchase price could be 30 euros.

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

1. Current Condition: The coin has a condition rating of 75 (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 in the past is 39.8 euros.
- Previous hammer prices for coins with similar conditions (around 75-80) have varied, but some have reached up to 440 euros in exceptional conditions.

3. Starting Price and Estimated Price:
- The current starting price is 25 euros, and the average starting price in the past has been 21.6 euros. This suggests that the starting price is reasonable and could attract bidders.

4. Sales Trends: The coin has been sold in 60 out of the 72 previous auctions, indicating good demand.

5. Comparison with Previous Prices:
- In previous auctions, coins with a condition of 75 have had hammer prices ranging from 30 to 95 euros, depending on demand and other factors.

Based on these points, an estimated maximum purchase price for this coin could be between 50 and 70 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate. However, given the interest and demand, a price of up to 80 euros could be reasonable if the auction generates competition among bidders.
