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 90 (EF), indicating that it is in very good shape. This generally increases its value compared to coins with lower conditions.

2. Auction History:
- The average hammer price in previous auctions is 24.25 euros.
- The most recent auction with a similar condition (80) had a hammer price of 55 euros.
- Overall, hammer prices have varied, but there are examples of auctions reaching up to 50 euros for condition ratings of 80.

3. Starting Price and Estimates:
- The current starting price is 25 euros, which is a good starting point.
- The estimated hammer price in previous auctions has reached up to 55 euros.

4. Sales Trends: The coin has sold in 16 out of 19 auctions, indicating good demand.

Based on these factors, an estimated maximum purchase price could be between 50 and 60 euros, given that the condition is high and there are precedents for hammer prices in that range. However, to be conservative and considering the starting price, a reasonable maximum purchase price could be 55 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 of 85 (ebc-), indicating that it is in quite good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Previous Prices: By looking at previous auction prices for coins with a similar condition (85), we find that at the auction on 2022-12-14, a coin with the same condition was sold for a hammer price of 90 euros. This suggests that the market has valued coins in this state at a high range.

3. Starting Price and Average Hammer Price: The current starting price is 40 euros, and the average hammer price in the past has been 37.11 euros. However, given that the condition is good and there is interest in the coin (sold 30 times in the past), it is reasonable to expect that the hammer price will be above the average.

4. Auction Trends: The coin has been auctioned 30 times and has had a 100% sell-through rate, indicating strong demand. This may influence an increase in the hammer price.

5. Estimation Based on Previous Prices: Since the highest hammer price for a coin with a similar condition was 90 euros, and considering that the starting price is 40 euros, an estimated maximum purchase price could be in the range of 80 to 100 euros, depending on the competition in the auction.

Conclusion: Based on all these factors, an estimated maximum purchase price for the coin could be approximately 90 euros. This reflects both the condition of the coin and the price trends in previous auctions.

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

1. Current Condition: The coin is in a condition of 90 (EF), indicating that it is in very good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Auction History:
- The average hammer price for similar coins in condition 90 has been 60.91 euros.
- In previous auctions, coins in condition 90 have sold for varying prices, but the last recorded hammer price was 240 euros, indicating a high selling potential for coins in this condition.

3. Starting Price and Average Starting Price:
- The current starting price is 60 euros, which is a good starting point, but the average starting price of 41.16 euros suggests that there may be competition keeping the price lower.

4. Demand and Supply: The coin has been auctioned 25 times, with a sell-through rate of 96% (24 out of 25), indicating a consistent interest in this coin.

5. Recent Trends: The last hammer price of 240 euros for a coin in condition 90 suggests that there is a market willing to pay more for coins in excellent condition.

Based on these factors, an estimated maximum purchase price could be in the range of 150 to 240 euros, considering that the highest recorded hammer price for a coin in similar condition was 240 euros. However, since the starting price is 60 euros, it is likely that the final hammer price will be closer to the average, so a reasonable maximum purchase price could be approximately 150 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 85 (ebc-), indicating that it is in fairly good shape. This suggests that its value should be above that of coins in worse conditions.

2. Previous Prices: By looking at previous auction prices, we can see that coins with similar conditions have reached auction prices that vary significantly. For example:
- A coin with a condition of 95 was auctioned for 800 euros.
- A coin with a condition of 90 was auctioned for 180 euros.
- A coin with a condition of 85 was auctioned for 75 euros (although the auction price of the last auction is not available).

3. Average Auction Price: The average auction price for this coin is 171.88 euros, which is also an important indicator.

4. Starting Price and Average Starting Price: The starting price is 60 euros, and the average starting price is 78 euros. This suggests that interest in the coin may be moderate, but not necessarily low.

5. Auction Trends: Given that there have been 10 previous auctions and all have resulted in sales, this indicates a consistent interest in the coin.

Based on these factors, an estimated maximum purchase price could be in the range of 150 to 200 euros, considering that the condition is good and the average auction price is 171.88 euros. However, since the condition is lower than the highest ratings, a more conservative price could be around 150 euros.

Therefore, a reasonable estimated maximum purchase price could be 150 euros.

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

1. Current starting price: 400 euros.
2. Current grade: 80 (MS+), which is a fairly good grade.
3. Auction history: The coin has been auctioned once before, with an estimated price of 250 euros and a hammer price of 180 euros. This indicates that interest in the coin may be moderate.
4. Average hammer price: 180 euros, which is significantly lower than the current starting price.

Since the current grade of the coin is better than that of the previous auction (80 vs. 75), this could justify a higher price. However, the starting price of 400 euros is quite high compared to the previous average hammer price.

Taking all these factors into account, an estimated maximum purchase price could be positioned between the previous average hammer price and a slight increase due to the better grade. It might be reasonable to estimate a maximum purchase price around 250-300 euros, considering that interest may not be high enough to reach the current starting price.

Therefore, an estimated maximum purchase price could be 300 euros.

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 of 80 (MBC+), which indicates that it is in quite good shape. This generally translates to a higher price compared to coins in lower condition.

2. Auction History:
- In the past, the coin has been auctioned 6 times, of which it has sold 4 times. This suggests that there is consistent interest in the coin.
- Previous hammer prices are relevant. For example:
- In 2020, it sold for 800 euros with a condition of 80.
- In 2020, with a condition of 85, it sold for 950 euros.
- In 2019, with a condition of 75, it sold for 500 euros.
- In 2022, with a condition of 80, it did not sell, but the starting price was 350 euros.
- In 2024, with a condition of 85, the starting price was 500 euros.

3. Starting Price and Average Hammer Price:
- The current starting price is 800 euros, which is consistent with previous starting prices.
- The average hammer price is 775 euros, indicating that, in general, coins of this reference tend to sell close to this price.

4. Estimation Based on Condition and Previous Prices:
- Given that the coin's condition is 80, and considering that it has sold for 800 euros in similar conditions in the past, an estimated maximum purchase price could be in the range of 800 to 950 euros, depending on the competition in the auction and the interest from collectors.

Conclusion: Based on the previous analysis, an estimated maximum purchase price for this coin could be approximately 900 euros. This takes into account the condition, price history, and interest in the coin.

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

1. Current asking price: 600 euros.
2. Coin condition: 80 (MS+), indicating good condition.
3. Auction history:
- The coin has been auctioned 7 times and has sold on all occasions.
- The average hammer price in previous auctions is 1085.86 euros.
- Previous hammer prices have varied, but generally, they have been in a range that suggests the coin has good market value.

4. Previous hammer prices:
- In 2020, with a condition of 80, it sold for 800 euros.
- In 2018, with a condition of 75, it also sold for 800 euros.
- In 2021, with a condition of 75, it sold for 900 euros.
- In 2024, with a condition of 75, it sold for 701 euros.

Given that the current condition of the coin is 80, which is higher than the conditions of 75 in previous auctions, we can infer that the hammer price could be higher than the 800 euros from previous auctions.

### Estimation of the maximum purchase price:
- Considering the average hammer price of 1085.86 euros and the history of hammer prices, a reasonable maximum purchase price could be in the range of 900 to 1100 euros, given that the condition is better than in previous auctions.

Therefore, an estimated maximum purchase price could be approximately 1100 euros.

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

- In previous auctions, hammer prices have been higher, especially when the condition was better (85 or above).

5. Maximum Price Estimate: Given that the current condition is 75, and considering that in previous auctions with similar conditions, hammer prices have reached up to 1100 euros, a reasonable maximum purchase price could be in the range of 1000 to 1100 euros. This is based on the fact that buyers may be willing to pay a little more than the most recent lower hammer price (900 euros) if demand is high.

Therefore, an estimated maximum purchase price for this coin could be approximately 1100 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 of 70 (MS-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Auction History:
- In the past, coins of the same reference with similar conditions (70 and 75) have been auctioned.
- Estimated prices for coins with a condition of 75 have reached up to 1300 euros, while for a condition of 70, estimated prices have been up to 500 euros.

3. Starting Price and Average Starting Price:
- The current starting price is 400 euros, which is lower than the average starting price of 500 euros. This may indicate a buying opportunity.

4. Sales Trends:
- Of the 5 times it has been auctioned in the past, it has only sold 2 times, which may indicate some resistance in the market for this coin.

5. Proximity of the Auction:
- There is an auction scheduled in the coming days, which may influence demand and price.

Based on these factors, an estimated maximum purchase price could be between 500 and 700 euros, considering that the condition is slightly lower than coins that have reached higher prices, but also taking into account the starting price and potential interest in the upcoming auction.
