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

1. Starting price: 350 euros.
2. Auction history: The coin has been auctioned 15 times, of which it has sold 10 times. This indicates a sell-through rate of 66.67%, which is quite positive.
3. Previous prices: Previous hammer prices for coins of similar condition (80) have varied, but the highest hammer price was 550 euros in March 2024. This suggests there is significant potential to reach high prices in recent auctions.
4. Average hammer price: The average hammer price of 292.3 euros is a good indicator of what buyers are willing to pay on average.
5. Condition: There is no information about the condition of this coin, which may make buyers more cautious. However, most coins in the history have a condition of 80, suggesting that the coin could be in a similar state.

Given that the starting price is 350 euros and considering the auction price history, an estimated maximum purchase price could be positioned between the starting price and the highest previous hammer price.

Taking all these factors into account, an estimated maximum purchase price could be approximately 450 euros. This reflects a balance between the starting price and the hammer price potential based on the auction history.

To estimate a maximum purchase price for the coin that is going to be auctioned, we can analyze the provided data, including previous hammer prices and the current starting price.

1. Current starting price: 400 euros.
2. Hammer price history:
- Previous hammer prices varied significantly, with some reaching up to 750 euros in recent auctions.
- The average hammer price in the past has been 163.09 euros, but there have been cases where much higher prices were reached, such as 500 euros and 750 euros.

3. Condition: There is no information about the condition of this coin, which may influence its value. However, in previous auctions, coins with similar conditions have reached high hammer prices.

4. Price trends:
- In the most recent auctions, hammer prices have shown an increase, suggesting that demand for this coin may be growing.
- The estimated price for the current auction is 1000 euros, indicating expectations that the coin could reach a high price.

5. Analysis of previous prices:
- The most recent auction with a starting price of 400 euros had a hammer price of 750 euros, suggesting that this could be a good reference point.

Based on these factors, an estimated maximum purchase price could be between 600 and 800 euros, considering that the starting price is 400 euros and there are precedents of high hammer prices in the past. This also takes into account the possibility that the coin may be valued higher in this auction due to the lack of information about its condition and the increasing trend in hammer prices.

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

1. Starting Price: 400 euros. This is the initial price set for the auction.
2. Auction History: The coin has been auctioned 2 times in the past and has sold on both occasions. This indicates interest in the coin and may positively influence its value.
3. Average Starting and Hammer Price: The average starting price of 255 euros and the average hammer price of 515 euros suggest that, in general, coins of this reference tend to sell for above their starting price.
4. Condition: There is no information about the condition of this coin, which may complicate the estimation. However, the previous hammer price of 130 euros for a coin with a condition value of 30 suggests that the price can vary significantly depending on the quality of the coin.
5. Previous Prices: In the previous auction, the coin sold for 130 euros, which is considerably lower than the current starting price of 400 euros.

Given that the starting price is significantly higher than the previous hammer prices, and considering that there is no information about the condition, it is prudent to be conservative in the estimation.

Taking all these factors into account, an estimated maximum purchase price could be between 300 and 350 euros, depending on the demand at the auction and the quality of the coin. This would allow for a competitive bid without exceeding the historical value of the coin.

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

1. Starting Price: 300 euros. This is the initial price expected to be obtained at the auction.

2. Auction History: The coin has been auctioned 7 times, of which it has sold 6 times. This indicates good demand and consistent interest in the coin.

3. Average Hammer Price: 243 euros. This is the average price at which the coins have sold in the past, which can be a good indicator of the coin's real value.

4. Condition: There is no information about the condition of this coin, which may complicate the estimation. However, in previous auctions, some coins with a condition of 70 have sold for prices ranging between 26 and 30 euros, suggesting that condition may influence the price.

5. Previous Prices: In the past, hammer prices have varied significantly, from 12 euros to 460 euros. The highest price (460 euros) was recorded in an auction where the starting price was 200 euros, indicating that there is potential for this coin to reach a high price if there is enough interest.

Given that the starting price is 300 euros and considering the average hammer price of 243 euros, an estimated maximum purchase price could be set in a range above the average price, but not as high as the starting price, especially since there is no information about the condition.

Estimated Maximum Purchase Price: It may be reasonable to estimate a maximum purchase price around 350-400 euros, assuming there is sufficient interest in the coin and that condition is not a limiting factor. This allows for a margin above the starting price, but also takes into account the history of hammer prices.

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

1. Starting price: 400 euros.
2. Auction history: The coin has been auctioned 10 times and has sold on all occasions, indicating good demand.
3. Average starting price: 114.44 euros.
4. Average hammer price: 209.9 euros.
5. Previous prices: Hammer prices have varied considerably, with a maximum of 440 euros in the 2022 auction and a minimum of 24 euros in 2016.

Since there is no information about the condition of the current coin, it is difficult to make an accurate estimate. However, we can observe that in previous auctions, hammer prices have fluctuated, but the highest price (440 euros) was reached in a recent auction with a condition rating of 95.

### Analysis of previous prices:
- The highest auction (440 euros) was conducted with a condition rating of 95.
- The lowest auction (24 euros) was conducted with an unspecified condition.
- Most hammer prices are below 300 euros, but there are a couple of exceptions that exceed that figure.

### Estimation:
Given that the starting price is 400 euros and considering that the average hammer price is 209.9 euros, it is reasonable to assume that the hammer price could be in a higher range due to demand and sales history.

Estimated maximum purchase price: It could be between 300 and 450 euros, considering that the starting price is 400 euros and that there have been recent sales exceeding 400 euros. A prudent maximum purchase price could be 450 euros, given the auction history and observed demand.

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

1. Current starting price: 500 euros.
2. Auction history: The coin has been auctioned 30 times, of which it has sold 27 times. This indicates a good sales rate (90%).
3. Average starting price: 191.79 euros.
4. Average hammer price: 233.85 euros.
5. Previous prices: There is a variety of hammer prices in the past, with some high hammer prices (for example, 750 euros in 2014 and 900 euros in 2022).

### Analysis of previous prices:
- The highest hammer prices have been for coins in grades of 100 and 95, suggesting that the coin's condition may significantly influence the price.
- The last auction with a starting price of 450 euros had a hammer price of 550 euros, indicating considerable interest in this coin.

### Maximum price estimation:
Since there is no information about the condition of the current coin, it is difficult to make an accurate estimate. However, considering the starting price of 500 euros and the history of hammer prices, a maximum purchase price could be situated between the starting price and the average hammer price.

- Starting price: 500 euros.
- Average hammer price: 233.85 euros (this is low compared to the current starting price).
- Highest hammer prices: Up to 750 euros in the past.

### Conclusion:
An estimated maximum purchase price could be 700 euros. This is based on the historical interest in the coin and the highest hammer prices observed, although the lack of information about the current condition may affect this estimate.

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

1. Condition of the coin: The coin to be auctioned has a condition rating of 90 (EBC), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Starting price and previous prices: The starting price is 400 euros. The average hammer price in previous auctions for this coin is 458.94 euros, suggesting that, in general, coins of this reference tend to sell for above their starting price.

3. Auction history: In the auction history, it is observed that coins with similar conditions have reached hammer prices that vary considerably, but there are examples of coins that have sold for significantly higher prices, especially those with superior conditions.

4. Recent trends: In the most recent auctions, hammer prices have been quite high, which could indicate an upward trend in interest for this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 600 to 800 euros. This is based on the fact that the condition is good and that the price history shows that similar coins have reached hammer prices in that range. However, since the starting price is 400 euros, it is likely that the hammer price will not significantly exceed this range unless there is strong competition among bidders.

Therefore, a reasonable maximum purchase price could be 700 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 conditions of the auctioned coins.

1. Current starting price: 400 euros.
2. Average hammer price: 308.5 euros.
3. Auction price history:
- Previous hammer prices varied significantly, with some reaching up to 1100 euros in higher conservation conditions (like 90).
- Most hammer prices fall between 150 and 500 euros, depending on the condition.

4. Condition: No specific information is provided about the condition of the current coin, making the estimation more complicated. However, we can observe that coins with conditions ranging from 70 to 90 have had hammer prices ranging from 200 to 600 euros.

5. Trends:
- Coins with higher conditions (80-90) tend to achieve higher hammer prices, while those with lower conditions (70 or less) have lower hammer prices.
- The coin with a starting price of 400 euros suggests that considerable interest is expected, which could indicate that the coin has a higher perceived value.

### Estimated maximum purchase price:
Given that there is no information about the condition, but considering the starting price and the auction price history, a reasonable maximum purchase price could be between 500 and 600 euros. This is based on the fact that the starting price is relatively high and that coins in similar conditions have reached hammer prices in that range.

Therefore, an estimated maximum purchase price could be approximately 600 euros.

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

1. Current starting price: 350 euros.
2. Auction history: The coin has been auctioned 7 times and has sold on all occasions, indicating a constant interest in the coin.
3. Previous prices:
- In 2019, it sold for 440 euros with a grade of 95.
- In 2015, it sold for 420 euros, although the grade is not specified.
- In other auctions, the hammer prices were significantly lower, suggesting that the coin's grade influences the price.

4. Average hammer price: 273.43 euros, indicating that, in general, coins of this reference tend to sell below the current starting price.

5. Grade: There is no information about the grade of the coin to be auctioned, which introduces uncertainty. However, the starting price is considerably higher than the average hammer price.

Given that the starting price is 350 euros and considering that the average hammer price is 273.43 euros, an estimated maximum purchase price could be positioned between the average hammer price and the starting price, taking into account the possibility that the grade is good.

Estimated maximum purchase price: It could be reasonable to consider a maximum purchase price of around 400 euros, as it is slightly higher than the average hammer price and below the starting price, which could be attractive to a buyer looking for a good opportunity.

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 quite good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Starting Price and Previous Prices: The current starting price is 700 euros. In previous auctions, the average hammer price has been 373.68 euros, but there are also examples of higher hammer prices, such as 800 euros in 2018 for a coin with a similar condition.

3. Historical Trends: The coin has been auctioned 59 times, with an 89.8% sell-through rate (53 out of 59). This suggests there is consistent interest in this coin, which may influence its price.

4. Recent Hammer Prices: In the most recent auctions, hammer prices have varied, but there are examples of auctions reaching up to 750 euros for coins in a condition of 90.

5. Comparison with Starting and Hammer Prices: Given that the starting price is 700 euros, and considering that in the past hammer prices have reached up to 800 euros for coins in similar conditions, it is reasonable to assume that the maximum purchase price could be in a similar range.

### Estimated Maximum Purchase Price
Taking all these factors into account, an estimated maximum purchase price for this coin could be between 800 and 900 euros. This is based on the good condition of the coin, the demonstrated interest in previous auctions, and the hammer prices achieved under 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 of 70 (VF-), indicating that it is in an acceptable state, but not among the best qualities. This may influence the price, as coins in better condition tend to reach higher prices.

2. Auction History:
- The coin has been auctioned 5 times in the past, of which it has sold 3 times. This indicates that there is interest in the coin, but also that there is a 40% chance it has not sold.
- Previous hammer prices are relevant. For example, in the 2019 auction, the coin sold for 950 euros with a condition of 80, and in 2024 it was hammered at 1100 euros with a condition of 75. This suggests that the price may fluctuate depending on the condition and market interest.

3. Starting Prices and Average Prices:
- The current starting price is 700 euros, which is lower than the average starting price of 840 euros and the average hammer price of 1016.67 euros. This suggests that the starting price is attractive and could attract more bidders.

4. Price Trends:
- The highest recorded hammer price is 1100 euros, which sets an upper limit for the purchase price.

Based on these factors, an estimated maximum purchase price could be between the average hammer price (1016.67 euros) and the highest hammer price (1100 euros). Given that the current condition is 70, which is lower than the conditions of previous auctions, a reasonable maximum price could be approximately 1000 euros. This reflects a balance between market interest, the condition of the coin, and historical prices.
