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 30 (BC+). This is relatively low compared to other coins that have been auctioned, which may affect its value.

2. Auction History:
- The average hammer price for similar coins is 31.43 euros.
- In previous auctions, hammer prices have varied, with some reaching up to 50 euros, but there are also examples of lower hammer prices, such as 15 euros.

3. Starting Price: The starting price is 25 euros, indicating that the seller expects a minimum of 25 euros, but this does not guarantee that it will sell at that price.

4. Sales Trends: Out of the 14 times it has been auctioned, it has sold on 10 occasions, suggesting there is moderate interest in this coin.

5. Comparison with Previous Prices:
- In recent auctions, the hammer price has ranged between 15 and 50 euros, depending on the condition and other factors.

Given that the condition of this coin is 30 (BC+), which is below the average of coins that have sold in the past, and considering the average hammer price, an estimated maximum purchase price could be set in a more conservative range.

Estimated Maximum Purchase Price:
Taking all these factors into account, a reasonable maximum purchase price could be between 25 to 30 euros. This is based on the starting price and the history of hammer prices, adjusted for the current condition of the coin.

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. Auction History:
- The average hammer price in previous auctions is 31.25 euros.
- In past auctions, coins with a similar condition (75) have had hammer prices that varied, but some examples are:
- 30 euros (auction on 2020-10-20)
- 40 euros (auction on 2022-02-22)
- 14 euros (auction on 2019-07-03)
- The trend shows that the hammer price can reach up to 40 euros in the case of good demand.

3. Starting Price: The starting price is 25 euros, which is a good starting point.

4. Demand and Supply: Since there are no auctions scheduled in the coming days, this could increase competition among interested bidders.

Based on these factors, an estimated maximum purchase price could be between 35 and 45 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate. A price of 40 euros could be a reasonable target, as it is a midpoint between the average hammer price and the higher prices observed in previous auctions.

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 70 (VF-), indicating that it is in acceptable shape, but not among the best qualities. This can influence the price, as coins in better condition tend to fetch higher prices.

2. Auction History: The coin has been auctioned 25 times in the past, of which it has sold 17 times. This indicates a consistent interest in the coin, which can increase its value.

3. Previous Auction Prices:
- The average starting price is 23.67 euros, and the average hammer price is 29.35 euros.
- In previous auctions, hammer prices have varied, but there are examples of sales reaching up to 65 euros under similar conditions.

4. Recent Trends: In the most recent auctions, the hammer price has been around 45 euros, suggesting that interest in the coin remains steady.

5. Current Starting Price: The starting price is 15 euros, which is relatively low compared to previous hammer prices.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 40 to 50 euros. This is based on the history of hammer prices and the current condition of the coin. However, since interest may vary and the auction may attract different bidders, it is advisable to be prepared to bid a little higher if competition is strong.

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 quite good shape. This generally increases its value compared to coins in lower condition.

2. Auction history:
- In the 2017 auction, the coin started at 18 euros and was sold for 20 euros.
- In the 2020 auction, it started at 12 euros and was sold for 12 euros.

3. Average hammer price: The average hammer price from previous auctions is 16 euros, which can serve as a reference.

4. Current starting price: The starting price is 15 euros, which is slightly lower than the average hammer price from previous auctions.

Given that the condition of the coin is good and considering the price history, an estimated maximum purchase price could be set between the average hammer price and a bit higher, since the condition is better than in some of the previous auctions.

Therefore, an estimated maximum purchase price could be approximately 25 euros. This is based on the fact that the condition is good and that interest in the coin could lead to a higher hammer price than average.

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

1. Starting Price: 15 euros.
2. Condition: The coin has a condition rating of 75 (MBC), indicating that it is in quite good shape.
3. Auction History:
- It has been auctioned 4 times in the past, of which it has sold 3 times.
- The average hammer price in previous auctions is 12.33 euros.
- The starting prices in previous auctions have been quite low, with a maximum of 10 euros and a minimum of 1 euro.

Given that the condition of the coin is quite good (75), and considering that the starting price is 15 euros, which is higher than the previous average hammer price, we can estimate a maximum purchase price.

A reasonable approach would be to consider an increase over the average hammer price, given that the condition is better than the coins auctioned previously. We could apply an adjustment factor based on the condition and market interest.

Estimation:
- Previous average hammer price: 12.33 euros.
- Adjustment for condition (considering that 75 is quite a good state): we could consider an increase of 20-30% over the average hammer price.

Calculating a 25% increase on 12.33 euros:
- 12.33 * 1.25 = 15.41 euros.

Therefore, an estimated maximum purchase price for this coin could be around 15-16 euros. This aligns with the starting price, suggesting that it could be a reasonable price for an interested buyer.
