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.

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

2. Auction History:
- The coin has been auctioned 8 times and has sold on all occasions, indicating good demand.
- Previous hammer prices have varied, but there are examples of hammer prices exceeding 1000 euros, especially for coins with similar conditions (95).

3. Starting Price and Average Price:
- The current starting price is 900 euros, which is higher than the average starting price of 711.25 euros. This suggests that the seller has high expectations for this auction.
- The average hammer price is 785.71 euros, indicating that, on average, coins of this reference have sold below their starting price.

4. Price Trends:
- In previous auctions, hammer prices have varied significantly, with some reaching up to 1600 euros. This suggests that there is potential for this coin to reach a higher price, especially if demand is strong.

5. Proximity of Other Auctions: There are 2 auctions scheduled in the coming days, which could influence competition and interest in the coin.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 1200 to 1500 euros. This is based on the hammer price history for coins of similar condition and the good demand observed in previous auctions. However, the final price will depend on the competition in the auction and the interest from collectors.

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

1. Condition: The coin to be auctioned has a condition of 95 (EBC+), which is quite high and suggests that the coin is in very good shape.

2. Previous auction prices:
- In previous auctions, coins with a similar condition (95) have had hammer prices that varied, but generally, the hammer prices have been in a high range. For example, in 2018, a coin with a condition of 95 was sold for 3600 euros and another for 1300 euros (although the latter had a lower starting price).
- In 2023, a coin with a condition of 85 was sold for 2700 euros, indicating that condition has a significant impact on price.

3. Average hammer price: The average hammer price for this particular coin is 3026.25 euros, which can serve as a good indicator of market value.

4. Starting price: The starting price of 1500 euros is relatively low compared to previous hammer prices, suggesting that there could be a good buying opportunity.

5. Auction trends: Given that the coin has sold in all previous occasions and has had a hammer price that exceeds the starting price, it is reasonable to assume that interest in this coin will remain.

Based on these factors, an estimated maximum purchase price could be in the range of 3000 to 3500 euros, considering that the average hammer price is 3026.25 euros and that the condition of the coin is high. This would allow for competitive bidding in the auction without exceeding the market value observed in previous auctions.

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

1. Starting price: 9000 euros.
2. Average hammer price in the past: 15000 euros.
3. Condition of the coin: 100 (Uncirculated), indicating that it is in excellent condition.
4. Auction history: It has been auctioned once before, with a hammer price of 15000 euros.

Given that the coin has a high condition rating and has reached a hammer price of 15000 euros in the past, it is reasonable to consider that interest in this coin could be high in the upcoming auction.

Estimation of the maximum purchase price:
- Since the average hammer price has been 15000 euros and considering that the coin is in the same condition as in the previous auction, a maximum purchase price could be around 15000 euros, as this is the price it has previously reached.

However, since the starting price is 9000 euros, it is possible that bidders may be willing to pay more, but the hammer price may not significantly exceed the previous price due to factors such as current demand and the number of bidders.

Therefore, an estimated maximum purchase price could be 15000 euros, but it is advisable to pay attention to the dynamics of the auction and the competition from other bidders.

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

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

- In March 2023, the coin had a starting price of 9000 euros and a final price of 9000 euros, indicating that it did not sell above its starting price, despite having an estimated price of 15000 euros.

3. Starting Prices and Average Prices:
- The current starting price is 8000 euros, which is lower than the average starting price of 8500 euros and the average final price of 10000 euros. This suggests that the starting price is attractive and could draw in more bidders.

4. Price Trends: Given that the coin has had a final price of up to 11000 euros in the past and considering its high condition, it is reasonable to expect that interest in the coin will remain.

Based on these factors, an estimated maximum purchase price could be in the range of 11000 to 13000 euros, considering that bidder interest could drive the price to a higher level, especially given the auction history and the coin's condition.

Therefore, a reasonable maximum purchase price could be 12000 euros.
