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 70 (MS-), indicating that it is in an acceptable state, but not of the highest quality.

2. Auction History:
- The average hammer price for coins of similar condition (70) in the past has been approximately 30.67 euros.
- In previous auctions, hammer prices for coins with a condition of 70 have varied, with some examples being:
- 65 euros in December 2018.
- 60 euros in July 2022.
- 40 euros on several occasions.

3. Starting Price: The current starting price is 60 euros, indicating that the seller has reasonable price expectations.

4. Sales Trends: The coin has been auctioned 53 times, of which it has sold 30 times. This suggests there is moderate interest in the coin, but also a significant number of coins that have not sold.

5. Estimated Price: The estimated price of 100 euros in the December 2020 auction for a coin in condition 70 suggests there is potential to reach higher prices, although this depends on demand at the time of the auction.

Based on these factors, an estimated maximum purchase price could be between 60 and 80 euros, considering that the starting price is 60 euros and that, in previous auctions, coins of similar condition have reached hammer prices of up to 65-70 euros. However, if there is strong demand at the auction, it could reach up to 80 euros.

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 70 (VF-). This indicates that it is in an acceptable state, but not of high quality. In comparison with previously auctioned coins, a condition of 70 is similar to one from past auctions.

2. Previous Prices:
- In the 2020 auction, a coin with a condition of 75 had a starting price of 18 euros, but it did not sell.
- In 2022, a coin with a condition of 90 sold for 140 euros, indicating that the price can significantly increase with better condition.
- In another 2022 auction, a coin with a condition of 70 had a starting price of 15 euros, but it did not sell.

3. Average Hammer Price: The average hammer price for similar coins is 140 euros, suggesting that there is a market willing to pay high prices for coins in good condition.

4. Starting Price and Estimates: The current starting price is 12 euros, which is quite low compared to the average hammer price. The average starting price of 31.25 euros also suggests that there is potential for price increase.

5. Demand and Supply: Given that there is an auction scheduled in the coming days and considering that there have been more auctions without sales, this may influence demand.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 30 to 50 euros, considering that the condition is a limiting factor and that the hammer price may be higher depending on demand at the auction.

Therefore, a reasonable maximum purchase price could be 40 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 30 (BC+), indicating that it is not in the best condition. This may negatively affect its value compared to coins in better condition.

2. Auction History:
- The coin has been auctioned 9 times, of which it has sold 6 times. This indicates moderate interest in the coin.
- Previous hammer prices have varied, but there are some hammer prices close to 30 euros, such as in the auctions of 2023 and 2017.

3. Starting Price and Average Hammer Price:
- The current starting price is 30 euros, and the average hammer price in the past has been approximately 26.17 euros. This suggests that the starting price is reasonable, but it may not sell for much more than that.

4. Price Trends:
- Estimated prices in previous auctions have been higher than the hammer prices, suggesting that buyers may be willing to pay more than what it ultimately sells for.

5. Comparison with Previous Prices:
- In previous auctions, the hammer price has reached up to 40 euros under similar conditions, although this is not common.

Taking all these factors into account, an estimated maximum purchase price could be around 35-40 euros. This is based on the historical interest in the coin and the fact that the starting price is reasonable, but it should also be considered that the condition is not the best. Therefore, a price of 35 euros could be a good starting point for an offer.

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 (MBC), indicating that it is in quite good shape. This generally translates to a higher price compared to coins in lower condition.

2. Auction History:
- The coin has been auctioned 15 times, of which it has sold 6 times. This suggests that there is moderate interest in the coin.
- The average starting price in previous auctions is 32.81 euros, and the average hammer price is 36.33 euros. This provides context regarding the market value of the coin.

3. Previous Prices:
- In recent auctions, the starting price has been 60 euros with an estimated price of 90 euros, indicating expectations for the coin to reach a higher price.
- In the most recent auction (2023-02-16), the starting price was 60 euros and the estimated price was 90 euros, suggesting that the market is willing to pay more for coins in good condition.

4. Price Trends:
- Looking at previous hammer prices, the highest recorded price was 50 euros in a 2016 auction, but in more recent auctions, the estimated price has increased, which could indicate an upward trend.

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 growing interest in the coin. A price of 80 euros could be a reasonable starting point for an offer, as it falls in the middle of this range and reflects both the condition and recent market trends.

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

1. Starting price: 25 euros.
2. Current condition: 30 (BC+), indicating a low condition.
3. Auction history: The coin has been auctioned 3 times and has sold on all occasions. The average hammer price has been 25 euros, suggesting that there has not been a significant increase in its value in the past.
4. Previous prices: In previous auctions, the starting price has varied, but the hammer price has consistently been low, especially for the current condition.

Given that the condition of the coin is low (30), and considering that the average hammer price has been 25 euros, it is reasonable to set a maximum purchase price that does not exceed the starting price, as demand and interest in coins in this condition tend to be limited.

Estimated maximum purchase price: 30 euros.

This price allows for a small margin over the starting price, but remains conservative given the sales history and the 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 rating of 25 (BC), indicating that it is not in very good shape. This generally reduces its value compared to coins in better condition.

2. Auction History:
- The coin has been auctioned 7 times, of which it has sold 6 times. This indicates good demand.
- Previous hammer prices varied, but there is a hammer price of 15 euros in 2019 and 30 euros in 2020 and 2023, suggesting that the price may fluctuate depending on the condition and demand at the time of the auction.

3. Starting Price and Average Hammer Price:
- The current starting price is 30 euros, which is higher than the average starting price of 23.63 euros. This may indicate that the auctioneer expects greater interest this time.
- The average hammer price is 28.33 euros, suggesting that, on average, similar coins have sold for a price close to this.

4. Comparison with Previous Prices:
- In previous auctions, the hammer price has ranged from 15 to 45 euros, depending on the condition of the coin.

Given that the current condition of the coin is 25 (BC), which is relatively low, and considering the price history, an estimated maximum purchase price could be around 25-30 euros. This is based on the fact that, although the starting price is 30 euros, the condition and price history suggest that achieving a higher hammer price may be difficult.

Therefore, a reasonable estimated maximum purchase price would be 25 euros.
