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

1. Condition: The coin has a condition of 70 (MS-), indicating that it is in acceptable shape, but not of the highest quality. This can influence the price, as coins in better condition tend to fetch higher prices.

2. Previous auction prices: By looking at the hammer prices of coins with a similar condition (70), we can see that they have ranged between 130 and 225 euros in previous auctions. For example, in several auctions, coins with a condition of 70 have sold for prices like 170, 220, and 190 euros.

3. Average hammer price: The average hammer price for this coin is 170.74 euros, which provides a good reference for the expected price.

4. Starting price: The starting price of the current auction is 140 euros, which is reasonable and may attract bidders.

5. Market trends: Since the coin has been auctioned 98 times and has sold 90 times, there is good demand and a history of successful sales, which may indicate that interest in this coin is strong.

Based on these factors, an estimated maximum purchase price could be around 200 euros. This price reflects a balance between the coin's condition, previous hammer prices, and market trends. However, it is important to keep in mind that the final price may vary depending on the competition in the auction and the interest of other bidders.

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

1. Coin Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in relatively good shape. This suggests that its value should be above that of coins with lower conditions.

2. Previous Auction Prices: By observing the hammer prices of coins with similar conditions (around 80), we can see that the hammer prices have varied. For example:
- In 2018, a coin with a condition of 80 was auctioned for a hammer price of 200 euros.
- In 2022, another coin with a condition of 80 was sold for 95 euros.

3. Average Hammer Price: The average hammer price for this coin is 233.42 euros, indicating that, in general, coins of this reference tend to reach higher prices.

4. Starting Price and Previous Hammer Prices: The current starting price is 40 euros, which is significantly lower than previous hammer prices. This could indicate a good buying opportunity.

5. Auction Trends: Given that there have been 58 previous auctions and 52 sales, demand appears to be high, which may influence the hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 200 to 300 euros, considering that the average hammer price is 233.42 euros and there are examples of previous sales exceeding 200 euros.

Therefore, a reasonable maximum purchase price could be 250 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 of 75 (MBC), which indicates that it is in fairly good shape, but not the best possible condition.

2. Previous Auction Prices:
- In 2015, a coin with the same condition (75) sold for 1103.45 euros.
- In 2016, a coin with better condition (85) sold for 2598.18 euros.
- The starting and final prices in previous auctions varied significantly, indicating that interest and demand can influence the final price.

3. Average Starting and Final Prices:
- The average starting price is 369.49 euros, and the average final price is 1074.51 euros. This suggests that, in general, coins of this reference tend to reach final prices significantly higher than their starting price.

4. Sales Trends: The coin has sold in 4 out of the last 5 auctions, indicating a consistent interest in this reference.

Given all this, and considering that the condition of the coin is 75, an estimated maximum purchase price could be in a range between the average final price and the highest price reached in previous auctions.

Therefore, an estimated maximum purchase price could be around 1000 to 1200 euros. This is based on historical interest and the final prices of similar coins in comparable conditions.

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

- The last auction with a similar condition (90) had a hammer price of 150 euros.

3. Starting Price and Average Starting Price:
- The current starting price is 110 euros, which is a good starting point.
- The average starting price of 77.57 euros suggests that, in general, coins of this reference tend to start at lower prices, but this may not reflect the actual value of the coin in good condition.

4. Recent Trends: In the most recent auction, a coin with a condition of 100 sold for 950 euros, indicating that there is a strong market for high-quality coins.

Based on these factors, an estimated maximum purchase price for the coin in condition 90 could be between 200 and 300 euros, considering that the average hammer price is 151.54 euros and there is potential for an increase due to the good condition and market demand.

Therefore, a reasonable maximum purchase price could be 250 euros.
