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 75 (MBC), indicating that it is in an acceptable state, but not among the best qualities.

2. Starting Price and Hammer Price: The current starting price is 75 euros, and the average hammer price in previous auctions is 141.96 euros. This suggests that, in general, coins of this reference tend to sell for a significantly higher price than their starting price.

3. Auction History:
- In the past, there have been auctions with hammer prices that varied considerably. For example, in 2015, a coin with a similar condition sold for 160 euros.
- There are also examples of coins with a condition of 75 that have sold for prices ranging from 50-100 euros in previous auctions.

4. Sales Trends: Of the 16 times it has been auctioned, it has sold 10 times, indicating a reasonable sell-through rate. However, there is also a significant number of times it has not sold (6), which may indicate that interest can vary.

5. Average Starting Price: The average starting price of 137.98 euros is a good indicator of what buyers are willing to pay on average.

Based on these factors, an estimated maximum purchase price could be between 120 and 160 euros, considering that the condition is 75 and that the average hammer price in the past has been approximately 141.96 euros.

Therefore, a reasonable maximum purchase price could be 150 euros. This allows for a margin to compete in the auction, given the history of hammer prices and the condition of the coin.

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

1. Current Condition: The coin has a condition of 75 (MBC), which indicates that it is in quite good shape. This generally translates to a higher price compared to coins in lower condition.

2. Historical Prices: By looking at previous auction prices, we can see that the coin has reached auction prices of up to 3400 euros in exceptional conditions (such as in the auction on 2022-03-17). However, the auction prices closer to the current condition (75) are more relevant. For example, in the auction on 2022-11-16, the hammer price was 40 euros, and in the auction on 2022-03-10, it was 55 euros.

3. Average Hammer Price: The average hammer price for this coin is 485.32 euros, suggesting that, in general, buyers are willing to pay a considerable amount for it.

4. Starting Price and Average Starting Price: The current starting price is 40 euros, and the average starting price is 125.14 euros. This indicates that the starting price is relatively low compared to what has been paid in the past.

5. Auction Trends: Given that there are 2 auctions scheduled in the coming days and that the coin has had a good sell-through rate (28 out of 30 auctions), this may increase competition and, therefore, the price.

Taking all these factors into account, an estimated maximum purchase price for the coin could be in the range of 200 to 300 euros, considering that the condition is good and there is historical interest in the coin. However, if strong competition arises in the auction, the price could exceed this range.

To estimate a maximum purchase price for the coin that is going to be auctioned, we can consider several factors based on the provided data:

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

2. Previous Prices: By observing the hammer prices of coins with similar conditions (85-95), we can see that the hammer prices have varied. For example, in previous auctions, coins with a condition of 85 have reached hammer prices of up to 270 euros.

3. Average Hammer Price: The average hammer price for this coin is 104.05 euros, which gives us a good reference for what buyers are willing to pay.

4. Auction Trends: The coin has been auctioned 137 times, of which 122 have been sold. This indicates a consistent interest in the coin, which may influence the price.

5. Starting Prices and Estimates: The starting price is 60 euros, and the average starting price is 69.23 euros. However, given that the condition is good and there is interest in the coin, it is reasonable to expect that the hammer price will be significantly higher.

Taking all these factors into account, an estimated maximum purchase price for this coin could be between 200 and 300 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate.

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 85 (ebc-), which is quite good. In the past, coins with this condition have reached auction prices of up to 232.93 euros.
