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 (VF), which indicates that it is in an acceptable state, but not of the highest quality.

2. Auction History:
- The average hammer price in previous auctions is 40.15 euros.
- The last auction where the coin was sold had a hammer price of 35 euros with a condition of 80.
- In previous auctions, hammer prices have ranged from 20 euros to 120 euros, depending on the condition.

3. Starting Price: The current starting price is 30 euros, which is a good starting point.

4. Price Trends: Observing previous hammer prices, it seems that the coin can reach higher prices depending on demand and condition.

Given that the condition of this coin is 75 and considering the average hammer price and previous auction prices, an estimated maximum purchase price could be around 50-60 euros. This is based on the fact that, although the condition is not the best, there is a price history suggesting it could reach a higher value in the market.

Therefore, an estimated maximum purchase price could be 60 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 rating of 75 (VF), indicating that it is in fairly good shape, but not the best possible condition.

2. Auction History:
- The average hammer price in the past has been 35.38 euros.
- The average starting price has been 36.73 euros.
- Coins with the same condition (75) have been auctioned in the past, and hammer prices have varied, with examples around 29.03 euros and 38 euros.

3. Recent Starting and Hammer Prices: In the most recent auctions, starting prices have ranged from 20 to 100 euros, with hammer prices reaching up to 110 euros for coins in better condition.

4. Market Trends: Given that the coin has been auctioned 69 times and has a 52% sell-through rate, this suggests there is moderate interest in this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 50 to 70 euros. This is because the starting price is 50 euros, and considering the auction history and current condition, a price of up to 70 euros could be reasonable for a buyer looking to secure the coin in a VF condition.

Therefore, the estimated maximum purchase price would 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), which indicates that it is in fairly good shape, but not the best possible condition.

2. Auction History:
- The average starting price from previous auctions is 36.01 euros, and the average hammer price is 49.88 euros.
- In the past, coins with a similar condition (75) have been auctioned, and the hammer prices have varied, with some reaching up to 180 euros in an auction.

3. Price Trends:
- The last auction for a coin with a condition of 85 had a hammer price of 55 euros, suggesting that the value may increase with better condition.
- The highest auction price for a condition of 75 was 180 euros, but that seems to be an exceptional case.

4. Current Starting Price: The starting price is 50 euros, indicating that the seller has reasonable price expectations.

Based on these factors, an estimated maximum purchase price could be in the range of 70 to 90 euros, considering that the condition is good and there is a price history that supports this estimate. However, since the starting price is 50 euros, it is likely that the hammer price will not significantly exceed this value unless there is active competition among bidders.

Therefore, a reasonable maximum purchase price could be 80 euros.
