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

1. Starting price: 450 euros.
2. Average hammer price in the past: 600 euros.
3. Coin condition: 100 (Uncirculated), indicating it is in excellent condition.
4. Historical data: In the previous auction, the coin was estimated at 1000 euros, but it sold for 600 euros.

Given that the coin has a high condition rating (100) and has had an average hammer price of 600 euros in the past, it is reasonable to consider that interest in this coin could be high, especially if it has sold well previously.

Taking these factors into account, an estimated maximum purchase price could be between the previous average hammer price (600 euros) and the previous estimated price (1000 euros). However, since the starting price is 450 euros, it is likely that bidders will be willing to pay a bit more.

Therefore, an estimated maximum purchase price could be approximately 800 euros. This reflects a reasonable interest in the coin, considering its condition and auction history.

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. Starting Price: The starting price is 6000 euros, which sets a baseline for the auction.

3. Auction History:
- In the past, it has been auctioned 3 times, of which it has sold 2 times and not sold 1 time.
- The previous hammer prices are 700 euros (2021), 850 euros (2022), and the last one has no hammer price, but it was estimated at 10000 euros with a starting price of 7000 euros.

4. Average Hammer Price: The average hammer price of 775 euros is quite low compared to the current starting price and the estimated prices in previous auctions.

5. Price Trends: The highest hammer price was 850 euros, suggesting that, despite the good condition, interest in this coin may not be as high as expected.

Given that the condition is high and the starting price is 6000 euros, but considering the hammer price history and the average hammer price, an estimated maximum purchase price could be set in a more conservative range.

Estimated Maximum Purchase Price: It may be reasonable to consider a maximum purchase price around 3000-4000 euros, as this reflects a balance between the good condition and the lower hammer price history. This also allows for some margin for competition in the auction.

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

1. Current Condition: The coin has a condition of 85 (MBC+/EBC-), indicating that it is in relatively good shape, but not of the best quality (FDC).

2. Auction History:
- The average hammer price for similar coins in the past has been 132.78 euros.
- In previous auctions, coins with similar conditions (85) have sold for varying prices, with some examples being:
- In 2020, a coin with a condition of 85 was hammered at 55 euros.
- In 2019, a coin with a condition of 90 sold for 185 euros.
- In 2022, a coin with a condition of 90 sold for 240 euros.

3. Starting Price: The starting price for this coin is 2500 euros, which is significantly higher than previous hammer prices for coins of similar condition.

4. Market Trends: Given that the coin has been auctioned 72 times in the past and has had a high sales percentage (67 out of 72), this suggests there is consistent interest in this coin.

5. Maximum Price Estimate: Based on the average hammer price and the hammer prices of coins with similar conditions, a reasonable maximum purchase price could be in the range of 150 to 250 euros, considering that the condition is good but not excellent.

Therefore, an estimated maximum purchase price for this coin could be 250 euros.

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

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

2. Auction History:
- The average hammer price for similar coins in the past is 39.86 euros.
- The coin has been auctioned 10 times, of which it has sold 7 times, indicating good demand.
- Previous hammer prices for coins with similar conditions (90 and 85) have varied, but the highest recorded price was 70 euros for a coin with a condition of 85.

3. Starting Price: The starting price of 110 euros is quite high, which may indicate that the seller has high expectations. However, the starting price does not always translate to the final hammer price.

4. Price Trends: Looking at previous hammer prices, it seems that coins with conditions between 80 and 90 have reached hammer prices ranging from 25 to 70 euros. Given that the coin in question has a condition of 95, it is reasonable to assume that it could reach a higher price.

Considering all these factors, an estimated maximum purchase price for the coin could be between 70 and 90 euros, considering that the condition is superior to coins that have reached higher hammer prices in the past. However, given the starting price of 110 euros, some bidders may be willing to pay more, but this will depend on the competition in the auction.

Therefore, a reasonable maximum purchase price could be 80 euros.

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

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

2. Previous Auction Prices: By observing the hammer prices of coins with similar conditions, we can see that:
- In 2019, a coin with a condition of 90 was sold for 950 euros.
- In 2021, a coin with a condition of 95 was sold for 1300 euros.
- In 2022, a coin with a condition of 90 was sold for 800 euros.

3. Average Hammer Price: The average hammer price for this coin is 621.13 euros, but since the condition of the coin being auctioned is higher, we can expect the hammer price to be higher.

4. Starting Price: The starting price is 900 euros, indicating that the seller has expectations of a relatively high hammer price.

5. Market Trends: Given that the coin has been auctioned 43 times and has had a high sales percentage (40 out of 43), this suggests that there is consistent interest in this coin.

Taking all these factors into account, an estimated maximum purchase price could be between 1200 and 1500 euros, considering that the condition is high and there are precedents for sales in that range for coins of similar quality.

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. Current Starting Price and Previous Prices: The current starting price is 450 euros. In previous auctions, we have seen hammer prices that vary, but there are examples of similar coins in comparable condition that have sold for significantly higher prices. For instance, in 2020, a coin with a condition of 95 sold for 550 euros, and in 2022, another with a condition of 95 was hammered at 700 euros.

3. Sales Trends: The coin has been auctioned 74 times, with a high percentage of sales (68 out of 74). This suggests that there is consistent interest in this coin, which may increase its value.

4. Average Hammer Price: The average hammer price for similar coins is 183.72 euros, but given that this coin's condition is superior, we can expect the hammer price to be higher.

5. Previous Estimates: In previous auctions, the estimated price for coins of similar condition has been up to 800 euros.

Taking all these factors into account, an estimated maximum purchase price for this coin could be between 600 and 750 euros, considering its good condition and market interest. However, given the starting price of 450 euros, it is likely that the hammer price will not exceed 700 euros in this specific auction.

Therefore, a reasonable maximum purchase price could be 700 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), indicating that it is in good shape. This is a positive factor that can increase its value.

- In past auctions, coins with similar conditions (around 90-95) have sold for prices that varied significantly, with some hammer prices reaching up to 5400 euros (as seen in the 2014 auction).

4. Price Trends: Observing the hammer prices of coins with similar conditions, it appears there is a wide range, but coins in better condition tend to fetch higher prices.

5. Market Expectations: Given that the coin will be auctioned in the near future and considering the potential demand, it is reasonable to expect that the hammer price could exceed the starting price.

Based on these factors, an estimated maximum purchase price could be between 4000 and 6000 euros, considering that the condition is high and there are precedents for successful sales in that range. However, the final price will depend on the competition in the auction and the interest of collectors.

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

1. 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. Previous Prices: By looking at previous auction prices for coins with similar conditions (95 and close), we can see that the highest auction price was 650 euros in 2020 for a coin with the same condition. There was also an auction for 1010 euros for a coin with a condition of 95 in 2014.

3. Average Auction Price: The average auction price for this coin is 231.98 euros, which provides a reference point.

4. Starting Price: The starting price is 250 euros, indicating that the seller expects a reasonable price for the coin.

5. Auction Trends: The coin has been auctioned 29 times, of which it has sold 27 times, indicating good demand.

Based on these factors, an estimated maximum purchase price could be in the range of 400 to 600 euros, considering that the condition is good and there are precedents of successful sales at higher prices. However, since the starting price is 250 euros, it is likely that buyers will be willing to bid beyond this price, especially if there is interest in the coin.

Therefore, an estimated maximum purchase price could be approximately 500 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 95 (S/C-), indicating that it is in very good shape. This generally increases its value compared to coins with lower conditions.

2. Previous auction prices: By looking at the hammer prices of coins with the same condition (95), we can see that they have reached hammer prices of up to 3200 euros in the past (in 2016). However, there are also more recent prices that are lower, such as 900 euros in 2018 and 1500 euros in 2024.
