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

1. Starting price: 500 euros.
2. Current condition: 70 (VG-), which is good condition, although not the best.
3. Auction history: The coin has been auctioned 2 times in the past, and both times it has sold. The average hammer price in the past was 1600 euros, indicating significant interest in this coin.
4. Previous hammer price: In the June 2021 auction, the coin was estimated at 1500 euros and sold for 1800 euros, suggesting there is potential for price increase depending on demand.

Given that the current condition is slightly lower than that of the previous auction (70 vs. 75), and considering that the average hammer price is 1600 euros, a reasonable maximum purchase price could be in the range of 1200 to 1400 euros. This would allow for competitive bidding in the auction without exceeding the historical value of the coin.

Therefore, an estimated maximum purchase price could be 1300 euros.

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 8 times and has sold on all occasions, indicating good demand.
3. Previous prices:
- The average hammer price in previous auctions is 391.25 euros.
- Hammer prices have varied, with a maximum of 460 euros in 2020 and 2023, and a minimum of 220 euros in 2019.
4. Condition: There is no specific information about the condition of the current coin, but in previous auctions, coins with conditions ranging from 80 to 95 have reached hammer prices between 220 and 460 euros.

Given that the starting price is 500 euros, which is above the historical average hammer price, and considering that the coin has a good sales history, we could estimate a maximum purchase price.

Estimation of the maximum purchase price:
- Based on the highest hammer price (460 euros) and the current starting price (500 euros), a reasonable maximum purchase price could be in the range of 450 to 500 euros, depending on the demand at the auction.

Therefore, an estimated maximum purchase price could be 450 euros. This allows for some margin for competition in the auction, while also staying within the limits of historical prices.

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

1. Starting Price: 700 euros.
2. Condition: The coin has a condition rating of 90 (XF), indicating that it is in very good shape. This generally increases its value compared to coins in lower condition.
3. Auction History: The coin has been auctioned twice in the past, and on one of those occasions, the hammer price was 5500 euros, with an estimated price of 2000 euros. This suggests that there is significant interest in this coin, especially in good condition.
4. Average Hammer Price: The average hammer price for this coin is 3900 euros, which also indicates a high potential value.

Given that the coin's condition is high (90) and considering the auction price history, an estimated maximum purchase price could be positioned in a range between the average hammer price and the highest recorded hammer price.

Therefore, an estimated maximum purchase price could be approximately 4500 to 5500 euros. This is based on the good condition and the demonstrated interest in previous auctions.

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

1. Current starting price: 600 euros.
2. Average hammer price in the past: 678.48 euros.
3. Hammer price history:
- Hammer prices have varied, with some reaching up to 1200 euros in higher conservation conditions (such as 100 and 95).
- Most hammer prices fall between 550 and 850 euros, depending on the conservation.

4. Condition of the coin: There is no information on the current condition, which can significantly affect the price. However, by observing the hammer prices of coins with similar conditions in the past, we can make an estimation.

5. Price trends:
- In previous auctions, coins with conditions ranging from 80 to 95 have had hammer prices between 550 and 900 euros.
- The most recent auction shows a hammer price of 721 euros, suggesting that interest in this coin remains strong.

### Estimation of the maximum purchase price:
Given that the average hammer price is 678.48 euros and considering that the starting price is 600 euros, a reasonable maximum purchase price could be in the range of 800 to 900 euros, assuming the coin has an acceptable condition.

Therefore, an estimated maximum purchase price could be approximately 850 euros. This allows for a margin for competition in the auction and aligns with previous hammer prices.

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 starting price.

1. Current starting price: 1000 euros.
2. Average auction price in the past: 871.41 euros.
3. Previous auction prices:
- Auction prices have varied considerably, with some reaching up to 2600 euros in very good condition (condition value 110).
- Most auction prices are in a range of 400 to 1000 euros, with some exceptional cases.

4. Condition of the coin: There is no information about the condition of this coin, which makes the estimation more uncertain. However, based on the auction prices of similar coins, we can make an assumption.

5. Auction price analysis:
- Coins with a condition of 80 to 95 have had auction prices ranging from 600 to 1000 euros.
- Coins with a condition of 100 and 110 have reached significantly higher auction prices, but we do not have information about the condition of this coin.

Given that the starting price is 1000 euros and considering that the average auction price is 871.41 euros, an estimated maximum purchase price could be set in a range that reflects both the starting price and the potential auction price based on the condition.

Estimated maximum purchase price:
- A reasonable maximum price could be 1200 euros. This is based on the starting price and the potential that, if the coin has an acceptable condition, it could reach an auction price higher than the average.

Therefore, a maximum purchase price of 1200 euros seems to be a prudent estimate, taking into account historical data and the lack of information about the condition.

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, but not the best possible condition. This may influence the price, as coins in better condition tend to fetch higher prices.

2. Starting Price and Average Hammer Price: The starting price is 1500 euros, and the average hammer price in previous auctions is 1506.88 euros. This suggests that the hammer price is usually close to the starting price.

3. Auction History: In the past, the coin has had several hammer prices. For example, in 2018 it was sold for 1100 euros with a condition rating of 95, and in 2021 it was sold for 1300 euros with a condition rating of 80. This indicates that the price can vary significantly depending on the condition and demand at the time of the auction.

4. Price Trends: Looking at previous hammer prices, the highest recorded price was 1755 euros in 2024, suggesting that there is potential for the price of this coin to increase based on demand.

Given all this, an estimated maximum purchase price could be around 1600-1700 euros. This range takes into account the current condition, price history, and the trend of increasing hammer prices. However, it is important to remember that the final price will depend on the competition in the auction and the specific demand at that time.

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

1. Starting Price: 1500 euros.
2. Condition: The coin has a condition rating of 85 (MBC+/EBC-), indicating that it is in fairly good shape.
3. Auction History:
- It has been auctioned 5 times in the past, of which it has sold 4 times.
- The average hammer price in previous auctions is 1775 euros.
- In the 2021 auction, with the same condition (85), it sold for 1600 euros.
- In the 2015 auction, it sold for 1200 euros, and in the 2024 auction, it sold for 2000 euros with a condition of 80.

4. Price Trends: The average hammer price has been increasing, and the highest recorded hammer price is 2000 euros.

Based on this data, the estimated maximum purchase price could be in a range between the average hammer price (1775 euros) and the highest recorded price (2000 euros). Given that the coin's condition is good and the starting price is 1500 euros, a reasonable maximum purchase price could be:

Estimated maximum purchase price: 1900 euros.

This price reflects a balance between the price history, the current condition, and the upward trend in hammer prices.

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

1. Current starting price: 3000 euros.
2. Average starting price in the past: 1202.27 euros.
3. Average final price in the past: 1941.55 euros.
4. Auction history: The coin has been auctioned 12 times, of which it has sold 11 times, indicating good demand.

### Analysis of previous prices:
- In 2020, a coin with a grade of 85 sold for 1250 euros.
- In 2020, another coin with a grade of 95 sold for 1300 euros.
- In 2021, a coin with a grade of 80 sold for 1300 euros.
- In 2024, a coin with a grade of 70 sold for 1500 euros.
- In 2024, a coin with a grade of 50 sold for 3400 euros.

### Considerations:
- The grade of the current coin is not specified, making it difficult to make a direct comparison.
- However, previous final prices suggest that, depending on the grade, the final price can vary significantly.
- The trend shows that coins with better grades tend to reach higher prices.

### Estimation:
Given that the starting price is 3000 euros, and considering that the average final price in the past is 1941.55 euros, a reasonable final price could be in the range of 2000 to 3000 euros, depending on the grade.

Estimated maximum purchase price: 2500 euros.

This price is based on the trend of previous final prices and the expectation that the coin could reach a higher price if the grade is favorable.

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

1. Starting price: 200 euros.
2. Auction history: The coin has been auctioned 23 times, of which it has sold 20 times. This indicates good demand.
3. Average hammer price: 115.58 euros, which is significantly lower than the current starting price.
4. Previous prices: Hammer prices have varied, with some reaching up to 301 euros in a recent auction, but there are also lower prices, such as 55 euros in other auctions.

Since there is no information about the condition of this coin, it is difficult to make an accurate estimate. However, we can consider the following points:

- The starting price of 200 euros is quite high compared to the average hammer price of 115.58 euros.
- The trend of hammer prices in the past shows that, although there are exceptions, most coins have sold for below the current starting price.

Based on these factors, an estimated maximum purchase price could be in a range between the average hammer price and the starting price. A reasonable approach would be to consider a maximum purchase price of around 150-180 euros, as this is above the average hammer price but still below the starting price, which could be attractive to a buyer looking for good value.

Therefore, the estimated maximum purchase price could be 180 euros.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the starting and hammer prices from previous auctions, as well as the coin's condition.

1. Current starting price: 2500 euros.
2. Average starting price in the past: 1415 euros.
3. Average hammer price in the past: 1396 euros.
4. Auction history: The coin has been auctioned 13 times, of which it has sold 10 times. This indicates good demand.
5. Condition: There is no information on the current condition, but in previous auctions, conditions have varied between 10 and 100.

### Analysis of previous prices:
- The auction with the highest hammer price was 4250 euros, although there is no information on the condition.
- The most recent auction with a known hammer price was 440 euros with a condition of 95.
- Hammer prices have varied considerably, suggesting that condition plays an important role in the final price.

### Estimation:
Given that the current starting price is 2500 euros and considering that the average hammer price in the past is 1396 euros, it seems that the starting price is quite high compared to the historical average. However, the good demand (10 out of 13 auctions sold) and the fact that there have been auctions with hammer prices above 4000 euros suggest that there could be significant interest.

If we consider that the starting price is an indicator of the seller's expectation and that the highest hammer price in the past was 4250 euros, an estimated maximum purchase price could be positioned between the starting price and the highest hammer price.

### Estimated maximum purchase price:
Estimation: 4000 euros.

This price reflects a balance between the current starting price and the history of hammer prices, taking into account demand and variability in condition.

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

1. Starting price: 1200 euros.
2. Auction history: The coin has been auctioned 20 times, of which it has sold 17 times. This indicates good demand.
3. Average hammer price: 1136.93 euros, which is a good indicator of the price buyers are willing to pay.
4. Condition: There is no information on the current condition of the coin, which may affect the price. However, in previous auctions, hammer prices have varied depending on the condition, with condition values ranging from 70 to 95.
5. Previous prices: Hammer prices have ranged from 580 to 3600 euros, depending on condition and other factors.

Given that the starting price is 1200 euros and the average hammer price is 1136.93 euros, an estimated maximum purchase price could be set in a range that considers demand and price history.

Taking all these factors into account, an estimated maximum purchase price could be approximately 1500 euros. This price reflects a margin over the starting price, considering the possibility that the coin has a favorable condition value and the trend of prices in previous auctions.

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+), indicating that it is in fairly good shape, but not the best possible condition.

2. Auction History:
- The average hammer price for similar coins has been 1136.93 euros.
- In previous auctions, coins with a similar condition (80) have reached hammer prices that vary, but some examples are:
- 700 euros (2021-03-18)
- 900 euros (2021-02-18)
- 950 euros (2023-02-16)
- 900 euros (2023-03-16)
- The trend shows that, although there are variations, the hammer prices for similar conditions have been in a range of 700 to 950 euros.

3. Starting Price and Average Starting Price:
- The current starting price is 500 euros, which is below the average starting price of 632.35 euros. This suggests that there is potential for the hammer price to be higher.

4. Demand and Supply: Since there are no auctions scheduled in the coming days, this could increase competition among bidders, which could drive up the hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 900 to 1200 euros, considering that the average hammer price has been 1136.93 euros and that the condition of the coin is good.

Therefore, a reasonable maximum purchase price could be approximately 1100 euros. This allows for some margin for competition in the auction, while also staying within the limits of what has been seen in the past for coins of similar condition.

To estimate a maximum purchase price for the coin in question, we will consider several factors, including the current condition of the coin, previous auction prices, and the starting price.

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

2. Previous auction prices:
- In previous auctions, we have seen hammer prices that vary significantly. For example, in 2020, a coin with a condition of 90 was auctioned for 1300 euros, while another with a condition of 85 sold for 1100 euros.
- In the most recent auction, a coin with a condition of 90 was hammered at 2300 euros, suggesting that there is a strong market for coins in good condition.

3. Average hammer price: The average hammer price for this coin is 1149.38 euros, which provides a useful benchmark.

4. Starting price: The starting price is 700 euros, which is reasonable given the history of hammer prices.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 1500 to 2300 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate.

Therefore, a reasonable maximum purchase price could be 2000 euros. This allows for some margin for competition in the auction, given the potential interest from other buyers.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data and make some comparisons.

1. Current coin data:
- Starting price: 6000 €

- Auction 1 (Grade 85): Hammer price 10000 €.
- Auction 2 (Grade 90): Hammer price 16000 €.
- Auction 3 (Grade 95): Hammer price 16800 €.
- Auction 4 (Grade 90): Hammer price 11750 €.

4. Analysis:
- The grade of the current coin (85) is similar to that of the first auction (also 85), where the hammer price was 10000 €.
- Coins with better grades (90 and 95) have reached significantly higher hammer prices (16000 € and 16800 €).
- Given that the current coin has a grade of 85, it is reasonable to expect that its hammer price will be in a range below 10000 €.

5. Estimation:
- Considering the starting price of 6000 € and the hammer price of 10000 € in the previous auction with the same grade, an estimated maximum purchase price could be around 9000 € to 10000 €, as this price reflects the demand and the grade of the coin.

Therefore, an estimated maximum purchase price for the coin in question could be approximately 9000 €.

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

5. Estimation: Given that the average hammer price is 1448.25 euros and considering that the starting price is 1000 euros, a reasonable maximum purchase price could be in a range above the starting price, but not as high as the average hammer price, given the lack of information about the condition.

Taking all these factors into account, an estimated maximum purchase price could be around 1200 to 1300 euros. This is based on the fact that the starting price is 1000 euros and the average hammer price is significantly higher, but also considering the lack of information about the current condition.

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 90 (EF), indicating that it is in good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Auction History:
- The average hammer price for coins of this reference is 574.1 euros, suggesting that, in general, buyers are willing to pay significantly more than the starting price.
- In previous auctions, we have seen hammer prices vary, but some have reached very high figures, such as 1800 euros in 2022 and 800 euros in 2023.

3. Starting Price and Average Starting Price:
