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

1. Starting Price: 300 euros.
2. Condition: The coin has a condition rating of 85 (MBC+/EBC-), indicating that it is in good condition. This generally can increase its value compared to coins with lower conditions.
3. Auction History: The coin has been auctioned 2 times in the past and has sold on both occasions. This suggests that there is interest in the coin and that it has an active market.
4. Previous Prices: In the November 2020 auction, the coin had a starting price of 250 euros and a hammer price of 420 euros. This indicates that the hammer price can be significantly higher than the starting price, especially if the condition is good.

Given that the average hammer price for similar coins is 585 euros and considering the condition of this coin, an estimated maximum purchase price could be in a range between the previous average hammer price and the current starting price.

Taking all these factors into account, an estimated maximum purchase price could be around 500 to 600 euros. This is based on market interest, good condition, and the hammer price history.

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

1. Current Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in quite good shape. This suggests that its value should be above that of coins with lower conditions.

2. Auction History:
- The average hammer price for coins of this reference is 757.22 euros.
- In previous auctions, hammer prices have varied, but there are examples of coins with similar conditions that have sold for prices ranging from 340 to 380 euros.
- The most recent auction with a condition of 100 reached a hammer price of 3000 euros, indicating a strong market for high-condition coins.

3. Starting Price and Average Starting Price:
- The current starting price is 250 euros, which is below the average starting price of 330 euros. This could indicate a buying opportunity at a reasonable price.

4. Sales Trends: The coin has been sold in 9 out of the last 10 auctions, suggesting there is consistent interest in this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 600 to 800 euros, considering that the condition is good and the auction price history supports a higher value. However, since the starting price is 250 euros, it could be a good opportunity to acquire it at a lower price if competition in the auction remains.

Therefore, a reasonable maximum purchase price could be 750 euros.

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

1. Starting price: 350 euros.
2. Average hammer price in the past: 800 euros. This indicates that, in the only previous auction, the coin sold for a significantly higher price than its starting price.
3. Condition of the coin: 85 (ebc-), which is a good condition, potentially increasing its value compared to lower-quality coins.
4. Auction history: The coin has been auctioned once and sold on that occasion, suggesting there is interest in the coin.

Given that the average hammer price was 800 euros and considering that the condition is good, an estimated maximum purchase price could be in the range of 800 to 1000 euros, depending on the demand in the current auction and the competition among bidders.

Therefore, an estimated maximum purchase price could be approximately 900 euros.

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

1. Condition: The coin to be auctioned has a condition of 95 (EBC+), indicating that it is in very good shape. This generally increases its value compared to coins with lower conditions.

2. Previous auction prices:
- In previous auctions, hammer prices have varied. The last auction with a condition of 75 had a hammer price of 1300 euros, while another with the same condition also had a hammer price of 1300 euros. The condition of 70 had a hammer price of 650 euros.
- This suggests that the hammer price can significantly increase with better condition.

3. Average hammer price: The average hammer price for coins of this reference is 1316.67 euros, providing a good benchmark.

4. Starting price: The starting price is 1100 euros, indicating that the seller has reasonable expectations for the price.

Given that the condition of the coin in the auction is significantly better than the previous ones (95 compared to 70 and 75), and considering the average hammer price, an estimated maximum purchase price could be positioned above the average hammer price.

Estimated maximum purchase price: It could be reasonable to estimate a maximum purchase price around 1500 euros, given the condition and the history of hammer prices. This allows for a margin for competition in the auction and the value that collectors may be willing to pay for a coin in such good condition.

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

1. Current starting price: 800 euros.
2. Average starting price in previous auctions: 612.5 euros.
3. Average hammer price in previous auctions: 1038.33 euros.
4. Auction history: The coin has been auctioned 6 times and has sold in all of them, indicating consistent interest.
5. Condition: There is no information about the current condition, but previous hammer prices varied according to the condition, with condition values ranging from 10 to 85.

Analyzing the previous hammer prices, we can observe that:

- In 2020, the hammer prices were 600 euros (with condition 80) and 650 euros (with condition 85).
- In 2021, the hammer prices were 680 euros (with condition 85) and 600 euros (with condition 70).
- In 2024, the hammer price was 1600 euros, but with a very low condition (10).

Since there is no information about the current condition, it is difficult to make an accurate estimate. However, considering that the average hammer price is 1038.33 euros and the starting price is 800 euros, a reasonable maximum purchase price could be in the range of the average hammer price.

Therefore, an estimated maximum purchase price could be around 1000 euros. This is based on the demonstrated interest in previous auctions and the average hammer price, taking into account that the condition of the coin may influence the final price.

To estimate a maximum purchase price for the coin that will be auctioned, we can analyze the provided data, especially previous auction prices and the current starting price.

1. Current starting price: 500 euros.
2. Average hammer price in the past: 655 euros.
3. Previous hammer prices:
- Hammer prices have varied, with some reaching up to 1200 euros in higher conservation conditions (such as 95 or 100).
- Most hammer prices are between 500 and 900 euros, depending on the conservation.

4. Conservation of the coin: There is no information about the conservation of this coin, which makes the estimation more uncertain. However, based on the hammer prices of coins with similar conservations (some with conservation of 80 and 85), we can infer that the hammer price could be in a similar range.

5. Analysis of previous prices:
- In previous auctions, coins with similar starting prices have had hammer prices ranging from 500 to 900 euros, depending on the conservation.
- The trend shows that the hammer price can be significantly higher than the starting price.

### Estimation of the maximum purchase price:
Given that the average hammer price is 655 euros and considering that the starting price is 500 euros, a reasonable maximum purchase price could be slightly higher than the average hammer price, especially if we consider the possibility that the coin has acceptable conservation.

Estimated maximum purchase price: 800 euros.

This price allows for a margin for competition in the auction and aligns with previous hammer prices for coins with similar characteristics.

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

1. Current starting price: 1200 euros.
2. Auction history:
- In 2020, the coin was auctioned with a starting price of 700 euros and sold for 1200 euros, with a condition rating of 80.
- In 2015, the starting price was 900 euros, but it sold for 950 euros, with no information on the condition.

3. Average starting price: 933.33 euros.
4. Average final price: 1416.67 euros.

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

- The highest final price in the past was 1200 euros, which matches the final price from the 2020 auction.
- The average final price (1416.67 euros) suggests that, in general, coins of this reference tend to sell for above their starting price.

Taking these factors into account, an estimated maximum purchase price could be in a range between the average final price and the highest final price observed.

Therefore, an estimated maximum purchase price could be approximately 1400 euros. This is based on the trend of previous final prices and the fact that the current starting price is 1200 euros.

To estimate a maximum purchase price for the coin that will be auctioned, we can analyze the provided data:

1. Current starting price: 500 euros.
2. Average starting price in previous auctions: 780 euros.
3. Average hammer price in previous auctions: 1294 euros.
4. Auction history: The coin has been auctioned 5 times and has sold on all occasions, indicating good demand.
5. Previous hammer prices: The hammer prices have varied, but the highest was 2600 euros in a recent auction with a grade of 95.

Since there is no information about the condition of the current coin, it is difficult to make an accurate estimate. However, considering the average hammer price of 1294 euros and the fact that the coin has a history of successful sales, we can make an estimation.

If we take into account the average hammer price and the fact that the starting price is relatively low (500 euros), we could estimate that the maximum purchase price could be in a range between the average hammer price and the highest recorded price.

Estimation of the maximum purchase price:
We could consider a maximum purchase price of around 1500 to 1800 euros, taking into account the price history and the lack of information about the condition. This would allow for a competitive bid without exceeding the historical hammer prices.

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

1. Current Condition: The coin has a condition rating of 95 (EF+), indicating that it is in very good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Starting Price and Previous Prices: The current starting price is 1500 euros, and the average hammer price in previous auctions is 2246.46 euros. This suggests that the hammer price tends to be significantly higher than the starting price.

3. Auction History: In the auction history, it is observed that coins with a similar condition (95) have reached hammer prices that vary, but many are above 2000 euros. For example, in previous auctions, they have sold for 2200 euros, 1850 euros, and in some cases even more.

4. Recent Trends: In the most recent auctions, the hammer price has been quite high, such as in the 2024 auction where it sold for 3200 euros.

Based on these factors, an estimated maximum purchase price could be in the range of 2200 to 2500 euros, considering that the average hammer price is 2246.46 euros and that the coin's condition is high. However, given the history of hammer prices in previous auctions, a reasonable maximum purchase price could be 2500 euros.

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

4. Market Trends:
- The coin has been auctioned 39 times, with a 77% sell-through rate, indicating consistent interest in this coin.
- The price trend appears to be increasing, especially for coins in higher condition.

Based on these factors, an estimated maximum purchase price for this coin could be between 2,000 and 2,500 euros. This is based on the auction price history for coins of similar condition and market interest. However, since the condition is not the highest, it is wise not to exceed the upper range too much.

Therefore, a reasonable maximum purchase price could be 2,200 euros.

3. Average hammer price: The average hammer price for this particular coin is 2980 euros, indicating that, in general, coins of this reference tend to sell within that range.

4. Starting price: The starting price is 1800 euros, which may attract more bidders, but it can also indicate that the seller is looking for a quick sale.

5. Market trends: Since the coin has been auctioned 10 times and all have been sold, this suggests a consistent demand.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 2800 to 3200 euros. This is based on the average hammer price and the condition of the coin. Therefore, a reasonable maximum purchase price could be 3200 euros.

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

1. Current starting price: 1500 euros.
2. Average starting price in previous auctions: 1648 euros.
3. Average hammer price in previous auctions: 1900.65 euros.
4. Hammer price history: Hammer prices have varied, with some reaching up to 3300 euros in previous auctions, although most have sold in a lower range.

Since there is no information about the condition of the current coin, it is difficult to make a direct comparison. However, we can observe that:

- Most coins with higher conditions (above 80) have had hammer prices ranging between 1500 and 2500 euros, with some exceptional cases reaching higher prices.
- The last auction with a hammer price of 4700 euros was conducted with a condition of 100, indicating that the quality of the coin has a significant impact on the price.

Taking these factors into account, an estimated maximum purchase price could be set in a range between the average hammer price (1900.65 euros) and the highest observed price (3300 euros), depending on demand and the quality of the coin.

Estimated maximum purchase price: 2500 euros.

This price reflects a balance between the price history and the uncertainty regarding the current condition of the coin.

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

4. Starting Price and Average Starting Price: The starting price is 2,000 euros, and the average starting price is 2,900 euros. This indicates that the current starting price is relatively low compared to the average hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 8,000 to 10,000 euros, considering that the condition is good and that interest in quality coins seems to be high. However, since the highest hammer price in the past was 34,000 euros, it is possible that some buyers may be willing to pay more, but this will depend on the competition in the auction and the interest of collectors at that time.

Therefore, a reasonable maximum purchase price could be approximately 9,000 to 10,000 euros.

Given that the average auction price is significantly higher than the current starting price, and considering that the coin has a history of successful sales, it can be inferred that there is potential for price increase.

However, the lack of information about the condition may make buyers more cautious. Therefore, an estimated maximum purchase price could be positioned between the average auction price and the average starting price, adjusted for the uncertainty of the condition.

Estimated maximum purchase price: 3500 euros.

This price reflects a balance between historical interest in the coin and the lack of information about its current state.

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

1. Current Condition: The coin has a condition rating of 85 (ebc-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Auction History:

5. Price trends:
- In previous auctions, hammer prices have exceeded the starting price in most cases, especially when the condition is good.
- In recent auctions, hammer prices have been significantly higher than the starting price, especially for coins with conditions of 90 or higher.

Given that the starting price is 1500 euros and considering the average hammer price of 1543.1 euros, as well as the hammer price history showing that coins can reach much higher prices depending on the condition, an estimated maximum purchase price could be:

Estimated maximum purchase price: 2200 euros.
