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

1. Current Grade: The coin has a grade of 70 (MS-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Previous Auction Prices: By observing the previous auction prices of coins with similar grades, we can see that there is a price trend that varies considerably. For example:
- A coin with a grade of 75 sold for 1125.97 and 537.97 in different auctions.
- A coin with a grade of 90 sold for 2500 and 5500 in other auctions.

3. Average Auction Price: The average auction price for this coin is 1484.65 euros, indicating that, in general, coins of this reference tend to sell for relatively high prices.

4. Starting Price: The starting price is 100 euros, suggesting that the auctioneer expects considerable interest in the coin.

5. Market Trends: Given that the coin has been auctioned 38 times in the past and has had a high sales percentage (35 out of 38), this indicates that there is an active market for this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 800 to 1200 euros, considering that the grade is slightly lower than some coins that have reached higher prices, but it is still a desirable coin with a history of successful sales.

Therefore, a reasonable maximum purchase price could be 1000 euros.

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

1. Starting Price: 50 euros.
2. Condition: The coin has a condition rating of 70 (VF-), indicating that it is in relatively good shape, but not the best possible condition.
3. Auction History: The coin has been auctioned 2 times in the past and has sold on both occasions. The previous hammer prices were 60 euros in 2014 and 65 euros in 2017.
4. Average Hammer Price: The average hammer price for this coin is 62.5 euros, which can serve as a reference.
5. Average Starting Price: The average starting price in previous auctions is 56.67 euros.

Given that the coin has a condition rating of 70 and considering the auction price history, an estimated maximum purchase price could be set in a range that reflects both the average hammer price and the current starting price.

Taking all these factors into account, a reasonable maximum purchase price could be approximately 70-75 euros. This is based on the fact that the condition is good and that the price history shows it has reached hammer prices close to this range in the past.

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

1. Starting Price: 60 euros. This is the initial price of the auction.
2. Condition: The coin has a condition rating of 75 (MBC), indicating that it is in fairly good shape, but not the best possible condition.
3. Historical Data: In the past, this coin was auctioned with a starting price of 110 euros and sold for 110 euros. This suggests that, despite a higher starting price, the interest in the coin was sufficient to reach the final price.
4. Average Starting and Final Prices: The average starting price is 85 euros and the average final price is 110 euros. This indicates that, generally, coins of this reference tend to sell for above their starting price.

Given that the coin has a condition rating of 75 and considering the historical and average prices, an estimated maximum purchase price could be in a range between the average final price and a bit more, given that the condition is good.

Therefore, an estimated maximum purchase price could be around 120-130 euros. This is based on the good condition and the demonstrated interest in previous auctions.

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

1. Current Grade: The coin has a grade of 75 (MS), indicating that it is in fairly good condition, but not of the highest quality (PR).

2. Previous Auction Prices: By looking at previous auction prices for coins with a similar grade (75), we can see that they have varied. For example:
- In 2011, a coin with a grade of 75 sold for 473.14 euros.
- In 2016, another coin with a grade of 75 sold for 120 euros.
- In 2019, a coin with a grade of 80 sold for 340 euros.

3. Average Auction Price: The average auction price for this coin is 519.38 euros, suggesting that, in general, coins of this reference tend to reach higher prices.

4. Starting Price: The current starting price is 125 euros, which is significantly lower than the average auction price.

5. Recent Trends: In the most recent auctions, the auction prices have shown a trend of being higher, especially for coins in good condition.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 300 to 500 euros, considering that the grade is 75 and the average auction price is 519.38 euros. However, since the starting price is 125 euros, it is possible that buyers may be willing to pay a bit more, but not necessarily reaching the average auction price.

Therefore, a reasonable maximum purchase price could be approximately 400 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 70 (MS-). This is an important factor, as coins in better condition tend to reach higher prices.

3. Average Auction Price: The average auction price for this coin is 295.72 euros, indicating that, in general, buyers are willing to pay around this figure.

4. Recent Trends: In the most recent auctions, the auction price has been around 320 euros, suggesting that there is an upward trend in interest for this coin.

5. Starting Price: The starting price is 275 euros, which is reasonable and aligns with previous auction prices.

Taking all these factors into account, an estimated maximum purchase price for this coin could be around 320-350 euros. This is based on recent interest and previous auction prices for coins of similar condition.
