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

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

2. Auction History:
- The coin has been auctioned 14 times, of which it has sold 8 times. This indicates considerable interest in the coin.
- Previous hammer prices for coins with similar conditions (70 and 75) have varied, but there is a hammer price of 346 euros in 2017 for a coin with unspecified condition, and 700 euros in 2023 for a coin with a condition of 80.

3. Starting and Hammer Prices:
- The current starting price is 40 euros, which is significantly lower than the average starting price of 330.36 euros and the average hammer price of 477.43 euros.
- In previous auctions, starting prices have varied, but the highest hammer price for a similar condition was 700 euros.

4. Price Trends:
- Hammer prices have shown an upward trend in recent years, especially in 2023.

Based on these factors, an estimated maximum purchase price could be set in a range that considers the interest in the coin, its condition, and previous hammer prices. Given that the most recent highest hammer price was 700 euros and considering that the current condition is 70, a reasonable maximum purchase price could be:

Estimated maximum purchase price: 500 - 600 euros.

This range takes into account the possibility that the coin could reach a higher price due to its demand and condition, but it also remains conservative compared to the highest hammer prices observed.

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 with lower conditions.

2. Auction History:
- The average hammer price for similar coins in MBC condition has been approximately 45 euros.
- In previous auctions, hammer prices for coins with similar conditions have varied, but there are examples of sales reaching up to 90 euros (as seen in the auction on 2020-09-17).

3. Starting Price and Average Starting Price: The current starting price is 25 euros, which is quite low compared to the average starting price of 47.45 euros. This suggests that there is potential for the hammer price to be significantly higher.

4. Recent Trends: In the most recent auctions, hammer prices have been in the range of 25 to 35 euros for coins with a condition of 70, indicating that interest in well-preserved coins remains strong.

5. Auction Expectations: Given that it will be auctioned in the coming days and considering historical interest, it is reasonable to expect that the hammer price will be above the starting price.

Based on these factors, an estimated maximum purchase price for this coin could be between 60 and 90 euros, considering that the condition is good and there is a price history that supports this estimate. A price of 75 euros could be a reasonable target, as it aligns with the average hammer price for coins in similar conditions.

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 80 (MS+), which is an acceptable level, but not among the highest. This may influence the price, as coins in better condition tend to fetch higher prices.

2. Starting Price and Historical Prices: The current starting price is 90 euros. Historically, the average hammer price for coins with a similar condition has been approximately 135-150 euros.

3. Sales Trends: Of the 45 times it has been auctioned in the past, it has sold on 34 occasions, indicating good demand. However, there is also a significant number of auctions where it did not sell, which may suggest that the starting price is an important factor.

4. Recent Hammer Prices: In the most recent auctions, hammer prices for coins with similar conditions have ranged from 110 to 170 euros.

5. Average Hammer Price: The average hammer price of 162.97 euros suggests that, under normal conditions, the coin could reach a higher price than the starting price.

Based on these factors, an estimated maximum purchase price could be around 150-170 euros, considering that the buyer might be willing to pay a bit more than the average hammer price, but not so much as to risk overpaying at an auction.

Therefore, a reasonable maximum purchase price could be 160 euros.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the previous auction prices and the current condition of the coin.

1. Current Condition: The coin has a condition of 75 (MBC), indicating that it is in a medium-low state of preservation. This is important because the auction price tends to be higher for coins in better condition.

2. Previous Auction Prices: By observing the auction prices of coins with a similar condition (75) and slightly better (80-85), we can see that:
- In previous auctions, coins with a condition of 75 have reached hammer prices of up to 60 euros (as in the auction on 2019-07-03).
- Coins with a condition of 80 have reached hammer prices of up to 45 euros (as in the auction on 2023-01-18).

3. Average Hammer Price: The average hammer price for this coin is 31.56 euros, which is also a good indicator.

Therefore, a reasonable maximum purchase price could be 75 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 (MBC), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The coin has been auctioned 6 times, of which it has sold 5 times. This indicates a consistent interest in the coin.
- The average hammer price in previous auctions is 106 euros, providing a good benchmark.
- In the most recent auction (2022), the coin sold for 220 euros, suggesting there is potential for a high price, especially if the condition is good.

4. Price Trends:
- Previous hammer prices varied, but the highest was 220 euros in 2022. This suggests that, although the starting price is low, interest in the coin may lead to a higher hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 150 to 220 euros, considering that the condition is good and there is a history of high prices in previous auctions. A price of 200 euros could be a reasonable target, as it falls in the middle of this range and reflects both the interest in the coin and its condition.

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

1. Starting price: 60 euros.
2. Average hammer price in the past: 135 euros. This indicates that, generally, coins of this reference tend to sell for a significantly higher price than their starting price.
3. Condition of the coin: 30 (BC+). This suggests that the coin has a low state of preservation, which could negatively affect its value compared to coins in better condition.
4. Auction history: The coin has been auctioned once and sold on that occasion, indicating that there is interest in it.

Given that the average hammer price is 135 euros, but the condition is low (30), it is reasonable to adjust the estimated price downward.

We could consider a range between the starting price and the average hammer price, taking into account the condition. One approach could be to calculate a percentage of the average hammer price that reflects the condition.

If we consider that the condition of 30 (BC+) could justify a discount of 30-40% off the average hammer price, we could estimate a maximum purchase price of approximately:

- Average hammer price: 135 euros
- 30% discount: 135 - (135 * 0.30) = 94.5 euros
- 40% discount: 135 - (135 * 0.40) = 81 euros

Therefore, an estimated maximum purchase price could be between 81 and 94.5 euros.

In summary, a reasonable maximum purchase price could be around 90 euros.

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

1. Starting price: 30 euros.

- In the past, this coin has been auctioned 4 times, of which it has sold 3 times. This suggests that there is interest in the coin, which may influence its price.
- Previous hammer prices are relevant. In the auctions of 2020 and 2022, the hammer prices were 25 and 60 euros, respectively, for conditions of 70. In the last auction, although the hammer price is unknown, the starting price was 70 euros with an estimated price of 110 euros.

3. Starting Price and Average Price: The current starting price is 50 euros, and the average starting price in the past has been 51.25 euros, with an average hammer price of 48.33 euros. This indicates that the market has valued this coin in a similar range in the past.

4. Price Trends: Given that the current condition of the coin is better than the previous ones (75 versus 70), it is reasonable to assume that the hammer price could be higher than the previous ones.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 70 to 90 euros, considering that the condition is better and that interest in the coin seems to be consistent. A price of 80 euros could be a reasonable starting point for an offer, as it is in the middle of this range and reflects an increase compared to previous hammer prices.
