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

1. Starting price: 1200 euros.
2. Average hammer price in the past: 1300 euros.
3. Condition of the coin: 100 (Uncirculated), indicating it is in excellent condition.
4. Auction history: It has been auctioned once before, with a hammer price of 1300 euros.

Given that the coin is in high condition and has reached a hammer price of 1300 euros in the past, it is reasonable to assume that interest in this coin will remain. Additionally, the fact that there have been no failed sale attempts suggests that there is demand.

Taking these factors into account, an estimated maximum purchase price could be slightly above the previous average hammer price, considering that the market may have evolved.

Therefore, an estimated maximum purchase price could be approximately 1400 euros. This reflects a slight increase over the previous hammer price, taking into account the good condition and potential demand.

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

1. Starting price: 1500 euros.
2. Average hammer price: 1600 euros.
3. Current condition: 95 (S/C-), which is good condition, although lower than the condition of 100 from the previous auction.
4. Historical data: In the previous auction, the coin was estimated at 1200 euros and sold for 1600 euros, with a condition of 100.

Since the current condition is slightly lower than that of the previous auction, this could influence the price. However, the starting price and the average hammer price are good indicators of demand and interest in the coin.

Taking all these factors into account, an estimated maximum purchase price could be around 1500-1600 euros, considering that the average hammer price in the previous auction was 1600 euros and that the current condition is good, although not as high as the previous one.

Therefore, a reasonable maximum purchase price could be 1600 euros.

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

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

2. Auction History:
- The average hammer price in previous auctions is 27 euros.
- The coin has been auctioned 14 times, of which it has sold 9 times, indicating good demand.
- Previous hammer prices varied, but there are examples of auctions reaching up to 110 euros under similar conditions.

3. Starting Price and Estimated Prices:
- The current starting price is 6 euros, which is relatively low compared to the average hammer price.
- The average starting price in previous auctions is 17.62 euros, suggesting that the current starting price could be a good opportunity.

4. Recent Trends: In the most recent auctions, estimated prices have been higher, suggesting that interest in this coin may be increasing.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 50 to 70 euros, considering that the condition is excellent and there is a history of hammer prices that supports this estimate.

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

1. Coin Condition: The coin to be auctioned has a condition of 100 (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 for similar coins in the past is 17.27 euros.
- The coin has been auctioned 50 times, of which it has sold 22 times, indicating a sell-through rate of 44%. This suggests that there is interest in the coin, but also that there is competition.

3. Previous Prices:
- In previous auctions, hammer prices have varied considerably, but there are examples of hammer prices reaching up to 225 euros (in the case of a condition of 85).
- The last auction of a coin with a condition of 100 had a hammer price of 40 euros.

4. Starting Price and Estimates:
- The starting price is 20 euros, which is a good starting point, but given the condition, it is likely that the hammer price will be significantly higher.

Taking all these factors into account, an estimated maximum purchase price could be between 40 and 60 euros, considering that the condition is high and there is demonstrated interest in previous auctions. However, given the price history, a maximum of 60 euros seems reasonable, as it aligns with the hammer prices of coins in similar conditions.

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 85 (ebc-), indicating that it is in quite good shape. This can positively influence its value.

2. Auction History:
- It has been auctioned 4 times in the past, of which it has sold 3 times. This suggests that there is interest in the coin.
- The average starting price in previous auctions is 172 euros, and the average hammer price is 158.67 euros. This indicates that, in general, the coin has sold for below its starting price.

3. Previous Prices:
- In the 2016 auction, the coin started at 250 euros and sold for 260 euros, showing that at that starting price, the coin has sales potential.
- In other auctions, the hammer prices have been lower, but they have also sold at lower starting prices.

4. Current Starting Price: The current starting price is 250 euros, which is consistent with previous starting prices.

Given that the coin has a history of successful sales at prices close to or above its current starting price, and considering its good condition, an estimated maximum purchase price could be around 300-350 euros. This is based on the estimated price from previous auctions and the demonstrated interest in past auctions.

Therefore, a reasonable maximum purchase price could be 350 euros.

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

1. Starting Price: 2500 euros. This is the initial price set for the auction.
2. Condition: The coin has a condition rating of 95 (S/C-), indicating that it is in very good shape. This generally increases its value.
3. Auction History:
- In the December 2021 auction, the coin was estimated at 1500 euros and sold for 3200 euros, indicating significant interest in this reference.
- In the June 2022 auction, although no final prices were provided, the starting price was 6000 euros, suggesting that the seller had high expectations, although the sale did not materialize.

4. Average Hammer Price: 1660.5 euros, which is an important figure for understanding the average value of the coin in the market.

5. Average Starting Price: 4250 euros, which is considerably higher than the current starting price of 2500 euros.

Given that the coin is in good condition and has shown interest in previous auctions, an estimated maximum purchase price could be in a range above the starting price, but also considering the average hammer price.

Taking all these factors into account, an estimated maximum purchase price could be between 3200 and 4000 euros, as this reflects both the interest shown in previous auctions and the good condition of the coin.

Therefore, a reasonable maximum purchase price could be 3500 euros.

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 95 (S/C-), indicating that it is in very good condition. This generally increases its value compared to coins with lower conditions.

2. Auction History:
- The average hammer price for this coin in the past has been 20.83 euros.
- In previous auctions, hammer prices have varied, but some relevant examples are:
- In 2020, a coin with a condition rating of 100 was sold for 18 euros.

4. Sales Trends: The coin has been sold in 73.33% of the auctions it has participated in, indicating good demand.

Based on these factors, an estimated maximum purchase price could be between 25 and 30 euros, considering that the condition is high and there are precedents for sales in that range. Therefore, a reasonable maximum purchase price could be 30 euros.

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

2. Auction History:
- The average hammer price for similar coins has been 68.71 euros.
- In previous auctions, hammer prices have varied significantly, but some relevant examples are:
- In 2022, a coin with a condition of 90 was sold for 200 euros.
- In 2020, a similar coin sold for 20 euros.
- In 2023, the hammer price was 55 euros.

3. Starting Price and Estimates:
- The current starting price is 15 euros, and the average starting price in the past has been 26.05 euros.
- The estimated price for this auction is 25 euros.

4. Sales Trends: Of the 20 times it has been auctioned in the past, it has sold 8 times, indicating a sales rate of 40%. This suggests that there is interest in the coin, but also that there is competition.

Based on these factors, an estimated maximum purchase price could be in the range of 70 to 100 euros, considering that the condition is good and there are examples of previous sales that reached higher prices. However, since the average hammer price is 68.71 euros, a reasonable maximum purchase price could be approximately 80 euros. This allows for a margin for competition in the auction and the possibility of the price rising due to demand.

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

1. Starting Price: 20 euros. This is the initial price of the auction.
2. Condition: The coin has a condition rating of 95 (EF+), indicating that it is in very good shape. This generally increases its value compared to coins in lower condition.
3. Historical Data: The coin was previously auctioned with a starting price of 60 euros and an estimated price of 80 euros, although it did not sell at that time. This suggests that the market has a higher value expectation for this coin.
4. Average Starting Price: 40 euros. This may be an indicator of the average value that buyers are willing to pay for similar coins.

Given that the condition is high and considering the previous starting and estimated prices, a reasonable maximum purchase price could be in the range of 80 to 100 euros. This is based on the expectation that, given the condition and interest in the coin, buyers may be willing to pay a higher price.

Therefore, an estimated maximum purchase price could be 90 euros.

Given that the coin has a conservation rating of 100 (S/C), which indicates that it is in very good condition, and considering that this is the first time it is being auctioned, the starting price is set at 1900 euros.

Without historical sales data for this coin, it is difficult to establish an exact hammer price. However, in the case of coins in high conservation condition, it is common for the hammer price to exceed the starting price, especially if there is interest among collectors.

Since there are no records of previous auctions and the starting price is reasonable, an estimated maximum purchase price could be between 2500 and 3000 euros, depending on the interest of the bidders in the auction. This is based on the trend that coins in excellent condition can reach significantly higher prices than their starting price.

Given that the coin has a conservation rating of 100 (S/C), which indicates that it is in excellent condition, and considering that the starting price is 2300 euros, we can estimate a maximum purchase price.

Since there are no historical auction data for this coin, it is difficult to make a direct comparison. However, in the collector's market, coins in high conservation condition often reach prices that can be significantly higher than the starting price, especially if there is demand.

Taking these factors into account, an estimated maximum purchase price could be between 3000 and 3500 euros, depending on the demand at the auction and the interest from collectors.

To estimate a maximum purchase price for the coin that will be auctioned, we will consider several factors:

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

2. Starting price: The starting price is 3500 euros. This is an important indicator, as it sets the starting point for the auction.

3. Auction history:
- It has been auctioned 34 times in the past, of which it has sold 23 times. This suggests that there is consistent interest in this coin.
- The average hammer price in previous auctions is 30.68 euros, but this seems to be for coins of lower condition, as hammer prices for coins in conditions similar to the current one (100) are significantly higher.
- In previous auctions, hammer prices for coins with a condition of 100 have reached up to 65 euros in the highest recorded case.

4. Recent trends: In the most recent auctions, the hammer price has shown an increase, which could indicate growing interest or value in this coin.

Given that the condition is high and the starting price is considerably higher than previous hammer prices, an estimated maximum purchase price could be a percentage of the starting price, adjusted for the condition and interest in the coin.

Estimation: Considering all these factors, a reasonable maximum purchase price could be in the range of 2000 to 2500 euros, as this represents a significant value in relation to the starting price and the condition of the coin. However, the interest of other bidders in the auction may also influence the final price.

- The average hammer price for this coin is 30.68 euros, suggesting that, in general, coins of this reference have sold for relatively low prices.
- However, there have been recent auctions where higher prices have been reached, such as the hammer price of 180 euros in May 2024 for a coin with unspecified condition, indicating that there is potential for value increase.

3. Starting price and previous prices:
- The current starting price is 30 euros, which is quite low compared to the average hammer price.
- In previous auctions, the hammer price has varied, but there are examples where prices of 45 euros and 65 euros have been reached for similar conditions.

4. Market trends: Given that the coin will be auctioned in the coming days and has a history of successful auctions, it is reasonable to assume that interest could be high, especially due to its good condition.

Taking all these factors into account, an estimated maximum purchase price could be between 50 and 70 euros. This is based on the potential of the coin's condition and market interest, as well as previous hammer prices. However, it is important to stay alert to the dynamics of the auction and the competition from other bidders.

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

1. Current Condition: The coin has a condition of 70 (MS-). This is an important factor, as coins in better condition tend to reach higher prices.

- The last auction for this coin in similar condition (95) had a hammer price of 160 euros.

4. Supply and Demand: The coin will be auctioned in the coming days, which may increase competition and, consequently, the final price.

Taking all these factors into account, an estimated maximum purchase price for this coin could be between 150 and 200 euros, considering its good condition and the price history in previous auctions. A price of 180 euros could be a reasonable target, given the current context and price trend.

Given that the coin is in a condition of 90 (EBC - Excellent Good Condition) and has not been auctioned or sold in the past, the starting price of 500 euros seems reasonable. However, since there are no historical sales data for this reference, it is difficult to establish a precise estimated maximum purchase price.

In general, coins in good condition (EBC) can reach prices above the starting price, especially if there is interest in the auction. Considering that this is the first time it is being auctioned and that the starting price is 500 euros, an estimated maximum purchase price could be in the range of 700 to 900 euros, depending on the interest of collectors and competition in the auction.

Therefore, an estimated maximum purchase price could be approximately 800 euros.

5. Estimated Price: The estimated price for this auction is 150 euros, which is also an important indicator.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 200 to 250 euros, given that there have been precedents of hammer prices in that range and the coin's condition is high. However, considering the starting price of 120 euros, it is likely that the hammer price will not significantly exceed this range unless there is strong competition in the auction.

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

5. Sales Trends: The coin has been auctioned 13 times, of which it has sold 10 times. This indicates a consistent interest in this coin.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 250 to 300 euros, considering that the condition is high and there are precedents of successful sales at higher prices. However, since the starting price is 250 euros, it is likely that the hammer price will not significantly exceed this value unless there is active competition among bidders.

Therefore, a reasonable maximum purchase price could be approximately 280 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 Prices: By looking at previous auction prices for coins with a similar condition (95), we find that in past auctions, the hammer price has been 220 euros (2018) and 190 euros (2017). This suggests that the market value for coins in this condition can be quite high.

3. Starting Price and Average Prices: The current starting price is 180 euros, and the average hammer price in the past has been 122 euros. However, given the high condition, it is reasonable to expect that the hammer price will be above this average.
