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 95 (EF+), indicating that it is in very good shape. This generally translates to a higher price compared to coins of lower condition.

2. Current Starting Price and Previous Prices: The current starting price is 1800 euros. In previous auctions, hammer prices for coins with similar conditions (around 90-95) have varied, but some have reached hammer prices of up to 1100 euros (as in the auction on 2018-03-08).

3. Price Trends: The average hammer price in previous auctions is 316.42 euros, but this includes coins of various conditions. Given that the current coin's condition is high, it is reasonable to expect that the hammer price will be significantly higher.

4. Comparison with Previous Hammer Prices: By observing the hammer prices of coins with similar conditions, we can see that they have reached prices of up to 1100 euros. However, since the current coin's condition is 95, it is possible that the hammer price could be higher.

5. Final Estimate: Taking all these factors into account, an estimated maximum purchase price could be between 1200 and 1500 euros, considering that the coin is in very good condition and that interest in high-condition coins may lead to an increase in the hammer price.

Therefore, an estimated maximum purchase price for this coin could be 1500 euros.

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), which indicates 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 similar conditions (85-90), we can see that auction prices have varied, but there are examples of auctions reaching up to 460 euros for condition 90.

3. Average Auction Price: The average auction price for this coin is 283.25 euros, which provides a baseline for the expected value.

4. Starting Price: The current starting price is 350 euros, suggesting that the seller has expectations of a higher auction price.

5. Auction Trends: The coin has been auctioned 22 times, with a high sales percentage (20 out of 22), indicating consistent demand.

Based on these factors, an estimated maximum purchase price could be in the range of 400 to 460 euros, considering that the condition is good and there are precedents for auctions in that range. Therefore, a reasonable maximum purchase price could be 450 euros.

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

1. Condition: The coin has a condition rating of 80 (MS+), 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 5 times in the past, of which it has sold 4 times. This indicates a consistent interest in the coin.
- Previous hammer prices are relevant. For example, in the 2020 auction, the coin sold for 1000 euros with a condition of 80. In other auctions, although the condition was slightly better (85), the hammer prices were lower (600 euros in 2021).

3. Average Hammer Price: The average hammer price of 592.5 euros is a good indicator of the current market value.

4. Starting Price and Estimates: The current starting price is 450 euros, and the average starting price is 437.5 euros. However, the estimated price of 1000 euros in the 2020 auction suggests there is potential for a higher price.

5. Recent Trends: In the most recent auctions, hammer prices have been lower (370 euros in March 2023), which could indicate a downward trend or an adjustment in demand.

Taking all these factors into account, an estimated maximum purchase price could be between 800 and 1000 euros, given the auction history and current condition. However, to be more conservative and considering recent trends, a safer maximum purchase price could be around 800 euros.

Given that the coin has a condition of 95 (EBC+), which is a very good condition, and considering that it is being auctioned for the first time, the starting price is set at 1500 euros.

In general, coins in similar conditions can reach hammer prices that are significantly higher than the starting price, especially if there is interest among collectors. However, since there are no historical sales data for this specific coin, it is difficult to make an accurate estimate.

Taking into account the starting price and the condition, an estimated maximum purchase price could be in the range of 2000 to 2500 euros, depending on the interest of the bidders at the auction. This is based on the assumption that the coin is attractive to collectors and that the condition is an important factor in its value.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the current condition of the coin (95, EBC+) and previous auction prices.

1. Condition: The coin has a condition of 95, indicating that it is in very good shape. This generally translates to a higher price compared to coins in lower condition.

2. Previous auction prices:
- In previous auctions, the hammer prices have varied, but there are some key points:
- In 2021, a coin with a condition of 90 sold for 650 euros.
- In 2023, a coin with a condition of 85 sold for 320 euros.
- In 2024, a coin with a condition of 85 sold for 500 euros.

3. Price trends:
- The average hammer price for coins of this reference is 358.75 euros, suggesting that the market is willing to pay around this amount on average.
- The current starting price is 400 euros, which is slightly higher than the average hammer price, but may be justified by the high condition of the coin.

4. Maximum price estimation:
- Given that the condition of the coin is high (95), and considering the previous auction prices, a reasonable maximum purchase price could be in the range of 600 to 700 euros, especially considering that in the past, hammer prices of up to 650 euros have been reached for coins in slightly lower condition.

Therefore, an estimated maximum purchase price for this coin could be 650 euros.

Given that the coin has a conservation rating of 100 (S/C), indicating that it is in almost perfect condition, and considering that this is the first time it is being auctioned, the starting price is set at 900 euros.

In this case, since there are no historical sales data for this coin, the estimated maximum purchase price could be slightly higher than the starting price, especially if there is interest in the coin.

An estimated maximum purchase price could range between 1,200 and 1,500 euros, depending on the demand at the auction. This is based on the high conservation rating and the novelty of the auction. However, the final price will depend on the competition among bidders.

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

1. Coin Condition: The coin has a condition rating of 100 (S/C), indicating that it is in very good condition. This generally translates to a higher price compared to coins with lower condition ratings.

2. Current and Previous Prices: The current starting price is 150 euros. In previous auctions, we have seen hammer prices that varied significantly, but there are examples of similar coins that have reached hammer prices of up to 700 euros (in the case of a coin with a condition rating of 110).

3. Price Trends: The average hammer price for similar coins is 104.51 euros, but there are examples of much higher hammer prices, especially for coins in conditions similar to the current one.

4. Supply and Demand: The coin has been auctioned 60 times in the past, with a sell-through rate of 91.67% (55 out of 60). This suggests that there is consistent interest in this coin.

5. Recent Hammer Prices: In the most recent auction, a similar coin was sold for 312 euros, indicating that there is potential for higher prices in the future.

Taking all these factors into account, an estimated maximum purchase price for this coin could be in the range of 300 to 400 euros, given its condition and the price trends in previous auctions. However, it is important to remember that the final price may vary depending on the competition in the auction and the demand at the time of sale.

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

1. Condition: The coin has a condition rating of 95 (S/C-), 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 approximately 300.88 euros, suggesting that this is a reasonable price to expect.
- In the most recent auction (2024-03-14), the coin was auctioned with a starting price of 125 euros and a hammer price of 300 euros, indicating that interest in this coin remains strong.

3. Previous hammer prices:
- In 2020, the coin sold for 1200 euros, but this may be an exceptional case due to the high condition (100) of that particular coin.
- In other auctions, hammer prices have varied, but they have generally remained in a range of 140 to 420 euros for similar conditions.

4. Current starting price: The starting price is 300 euros, indicating that the seller expects the coin to sell within that range.

Based on these factors, an estimated maximum purchase price could be between 400 and 600 euros, considering that the condition is high and that interest in the coin seems to be maintained. However, since the average hammer price is approximately 300.88 euros, a more conservative purchase price could be around 400 euros, while a more optimistic price could go up to 600 euros if there is competition in the auction.

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 95 (EBC+), indicating that it is in very good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price for this coin in the past is 106.71 euros.
- There have been significantly higher hammer prices recorded, such as 1100 euros in December 2020 for a coin with a condition of 100.
- Other hammer prices for coins with similar conditions (95) have ranged between 160 and 280 euros.

3. Starting Price and Estimated Price:
- The current starting price is 300 euros, which is considerably higher than the average starting price of 48.11 euros. This may indicate an expectation of high demand or a perceived higher value by the seller.

4. Recent Trends: In the most recent auctions, hammer prices for coins with conditions of 95 have been 160 euros and 180 euros.

Based on these factors, an estimated maximum purchase price could be between 300 and 400 euros, considering that the starting price is 300 euros and there are precedents of higher hammer prices for coins in similar conditions. However, since the starting price is already 300 euros, it is reasonable to think that a hammer price in the range of 350 to 400 euros could be a realistic target, depending on the competition in the auction.

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

1. Condition: The coin has a condition rating of 95 (S/C-), which is quite high. This generally indicates that the coin is in very good shape, which can increase its value.

2. Auction History:
- The average hammer price for this coin in the past is 555.75 euros.
- In previous auctions, hammer prices have varied, but there are several examples where the coin has sold for over 600 euros, especially in similar conditions.

3. Starting Price: The current starting price is 450 euros, which is reasonable given the price history.

4. Recent Trends: In the most recent auctions, hammer prices have been in the range of 600 to 900 euros, suggesting that there is growing demand for this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 650 to 750 euros. This is based on the hammer price history and the high condition of the coin. However, since the market can be volatile, it is important to consider the competition in the auction and the willingness of other bidders to pay.

Given that the coin has a grade of 95 (S/C-), which is a very high grade, and considering that this is the first time it is being auctioned, the starting price is set at 1500 euros.

In previous auctions, coins with similar grades have reached hammer prices that are often significantly higher than the starting price, especially if demand is high. However, since there are no historical sales data for this particular coin, it is difficult to make an accurate estimate.

Taking into account the grade and the starting price, a maximum estimated purchase price could be in the range of 2000 to 2500 euros, depending on the competition in the auction and the interest from collectors. This is based on the trend that coins in similar conditions can achieve prices above the starting price.

Given that the coin has a conservation rating of 100 (S/C), indicating that it is in almost perfect condition, and considering that it is being auctioned for the first time, the starting price is set at 900 euros.

In this case, since there are no historical sales data for this coin, and the starting price is the same as the average starting price, it can be estimated that the interest in the coin could be high, especially due to its excellent condition.

Taking these factors into account, an estimated maximum purchase price could range between 1,200 and 1,500 euros, depending on the demand at the auction. This is based on the possibility that collectors may be willing to pay a premium for a coin in such good condition that has not been auctioned before.

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

1. Condition: The coin has a condition of 100 (MS), indicating that it is in excellent shape. This generally increases its value compared to coins with lower conditions.

2. Previous auction prices:
- In 2019, a coin with a condition of 100 sold for 1600 euros.
- In 2021, a coin with a condition of 95 sold for 2800 euros.
- In 2020, a coin with a condition of 95 sold for 1200 euros.
- In 2015, coins sold for hammer prices of 2500 and 2600 euros, although the condition is not specified.

3. Average hammer price: The average hammer price for this coin is 2133.33 euros, which provides a good reference.

4. Starting price: The starting price is 1800 euros, indicating that the seller expects a minimum of 1800 euros.

5. Price trends: Observing previous hammer prices, it seems there is a price range that varies between 1200 and 2800 euros, depending on the condition and demand at the time of the auction.

Given that the coin has a high condition and considering previous hammer prices, an estimated maximum purchase price could be around 2500-2800 euros, as this reflects both the quality of the coin and price trends in previous auctions.

Therefore, an estimated maximum purchase price could be approximately 2700 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 the past: 1700 euros.
3. Average hammer price in the past: 2300 euros.
4. Condition of the coin: 95 (S/C-), which is a high condition.
5. Auction history:
- In 2015, it started at 1800 euros and was hammered at 2100 euros.
- In 2014, it started at 2000 euros and was hammered at 2100 euros (condition 95).
- In 2021, it was hammered at 3000 euros (condition 95).
- In 2023, it started at 1500 euros and was hammered at 2000 euros.

Given that the coin has a high condition (95) and has a history of hammer prices exceeding the current starting price, we can consider that the hammer price could be in a higher range.

### Analysis:
- The average hammer price (2300 euros) and previous hammer prices (2100 and 3000 euros) suggest that there is significant interest in this coin.
- The last auction in 2023 had a hammer price of 2000 euros, indicating that interest remains.

### Estimation:
Taking all these factors into account, an estimated maximum purchase price could be between 2300 and 2500 euros, as this price reflects both market interest and the condition of the coin.

Estimated maximum purchase price: 2500 euros.

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

1. Starting price: 300 euros.
2. Current condition: 95 (EBC+), which is a very good condition.
3. Auction history: The coin has been auctioned once before, with an estimated price of 500 euros and a hammer price of 460 euros, with a condition of 90.
4. Average hammer price: 460 euros, which is a good indicator of market value.

Since the current condition (95) is better than the condition of the previous auction (90), it is reasonable to assume that the hammer price could be higher than before.

Taking into account the average hammer price of 460 euros and the fact that the condition is better, an estimated maximum purchase price could be in the range of 460 to 500 euros.

Therefore, an estimated maximum purchase price could be 500 euros.

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

1. Starting price: 1800 euros.
2. Current condition: 95 (EBC+), which is a very good condition, although lower than the condition of 100 (FDC) from the previous auction.
3. Average hammer price in the previous auction: 1800 euros, which matches the current starting price.
4. Estimated price in the previous auction: 3000 euros, indicating that there was an expectation of higher value on that occasion.

Since the current condition is lower than that of the previous auction, it is reasonable to adjust the estimated price downward. However, the good condition (EBC+) and the fact that there have been no failed sale attempts suggest that there is interest in the coin.

Taking these factors into account, a maximum estimated purchase price could be positioned between the starting price and the previous estimated price. A reasonable range could be:

- Maximum estimated price: 2200 - 2500 euros.

This reflects an increase over the starting price, considering the good condition and interest in the coin, but also acknowledges that it will not reach the estimated price of 3000 euros due to the difference in condition.

Based on the provided data, we can conduct an analysis to estimate a maximum purchase price for the coin in question.

1. Starting price: 900 euros.
2. Condition: 95 (EBC+), indicating that the coin is in very good condition.
3. Auction history: The coin has been auctioned once before, with a hammer price of 900 euros, which matches the current starting price.
4. Previous estimated price: In the previous auction, the estimated price was 1000 euros, but the hammer price was 900 euros.

Given that the coin has a history of successful sales at 900 euros and considering its high condition (95), it is reasonable to think that interest in the coin could remain stable or even increase, especially if there is more demand in the current auction.

Estimation of the maximum purchase price:
- Since the previous hammer price was 900 euros and the estimated price was 1000 euros, a maximum purchase price could be set between these two values.
- Considering the condition and potential interest, a reasonable maximum purchase price could be 1000 euros.

This allows for a margin for competition in the auction, given that the starting price is 900 euros and there is a history of interest in the coin.

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

1. Starting Price: 2000 euros. This is the initial price of the auction.
2. Condition: The coin has a condition rating of 95 (S/C-), indicating that it is in very good shape.
3. Auction History:
- In 2020, it was auctioned with a starting price of 3000 euros, but the final price is unknown.
- In 2021, it was auctioned with an estimated price of 3000 euros and sold for 2800 euros.
- In 2022, it was auctioned with a starting price of 2000 euros and sold for 3600 euros.

4. Average Final Price: 3200 euros, indicating that, in general, coins of this reference tend to sell for a price higher than the starting price.

5. Average Starting Price: 2333.33 euros, which is slightly higher than the current starting price.

Given that the coin is in good condition and considering the history of final prices, an estimated maximum purchase price could be positioned in a range between the average final price and the highest recorded final price.

Taking all this into account, a reasonable maximum purchase price could be approximately 3600 euros, which is the highest recorded final price in the past for a coin of similar condition. This also aligns with the estimated price of 3500 euros from the previous auction.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the current condition of the coin (95, EBC+) and the hammer prices from previous auctions.

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

2. Previous hammer prices:
- In previous auctions, we have seen hammer prices of 1600 (with condition 95), 1100 (with condition 95), and other lower prices for lesser conditions.
- The average hammer price for coins of similar condition (95) seems to be in the range of 950 to 1600 euros.

3. Starting price and estimates:
- The current starting price is 1000 euros, which is reasonable given the price history.
- The average hammer price in the past has been 785.71 euros, but this may be influenced by coins of lower condition.

4. Auction trends:
- Since the coin has sold on all previous occasions and considering that there are two auctions scheduled in the future, this may increase competition and, therefore, the price.

Based on these factors, an estimated maximum purchase price could be in the range of 1500 to 1800 euros, considering the good condition and the history of hammer prices. This would allow a competitive buyer to secure the coin without exceeding a reasonable limit based on the market.
