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, the average hammer price has been 354.02 euros, suggesting that coins of this reference tend to sell below their starting price.

3. Sales History: The coin has been auctioned 57 times, of which 51 have been successful sales. This indicates good demand and consistent interest in this coin.

4. Previous Hammer Prices: Looking at previous hammer prices for coins with similar conditions (80-90), we can see that they have reached hammer prices that vary, but some have exceeded 400 euros, especially in higher conditions.

5. Recent Trends: In the most recent auctions, hammer prices have shown a trend of stabilizing or slightly increasing, which could indicate a rise in demand.

Based on these factors, an estimated maximum purchase price could be in the range of 500 to 600 euros. This is because, although the starting price is 450 euros, the good condition and price history suggest that there could be competition in the auction, which could lead to a higher hammer price.

Therefore, a reasonable maximum purchase price could be 550 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 (EBC+), indicating that it is in very good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Current Price and Previous Prices: The current starting price is 125 euros. In previous auctions, we have seen hammer prices that vary significantly, but there are examples of coins with similar conditions that have sold for significantly higher prices. For instance, in a previous auction, a coin with a condition of 95 sold for 380 euros.

3. Price Trends: The average hammer price for similar coins is 51.28 euros, but this may be influenced by coins with lower conditions. Given that the condition of this coin is high, it is reasonable to expect that the hammer price will be above the average.

4. Supply and Demand: The coin has been auctioned 168 times, of which it has sold 136 times. This indicates good demand, which can drive up the price.

5. Comparison with Previous Prices: In the auction history, there are examples of coins with a condition of 95 that have sold for prices ranging from 100 to 460 euros. This suggests that there is a wide price range depending on demand at the time of the auction.

Taking all these factors into account, an estimated maximum purchase price for this coin could be between 200 and 300 euros, considering its high condition and the price trends in previous auctions. However, given the starting price of 125 euros, it is possible that buyers may be willing to bid more, especially if there is interest in the coin.

Given that the coin has a conservation rating of 85 (MBC+/EBC-), indicating good quality, and considering that this is the first time it is being auctioned, the starting price is set at 25,000 euros.

In previous auctions, the hammer price has not been recorded, suggesting that there is no historical data that could influence the estimation. However, since the starting price is the same as the average starting price, this may indicate that the seller is confident in the value of the coin.

Since there are no previous sales and the conservation is good, an estimated maximum purchase price could be slightly higher than the starting price, but not by much, as there are no precedents to justify a significant increase.

Therefore, an estimated maximum purchase price could range between 25,000 and 30,000 euros, depending on the interest of collectors and the competition in the auction.

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

1. Starting price: 35,000 euros.
2. Average hammer price in the past: 44,000 euros.
3. Condition of the coin: 95 (EF+), indicating good preservation.
4. Auction history: It has been auctioned once before, with a hammer price of 44,000 euros, which matches the estimated price in that auction.

Given that the coin is in good condition and has reached a hammer price of 44,000 euros in the past, it is reasonable to consider that interest in this coin could remain stable or even increase, especially if there is more demand in the current auction.

Taking these factors into account, an estimated maximum purchase price could be around 45,000 to 50,000 euros, considering that the previous hammer price was 44,000 euros and that the condition is high. This also allows for a margin for competition in the auction.

Therefore, an estimated maximum purchase price could be 45,000 euros.

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. Previous auction prices:
- The average hammer price for this coin has been approximately 2993.48 euros.
- In previous auctions, the hammer price has varied, but it has reached up to 6500 euros on some occasions, especially in similar conditions.

3. Starting price: The current starting price is 3000 euros, which is a reasonable starting point.

4. Sales trends: The coin has sold in 24 out of the last 26 auctions, indicating good demand.

5. Estimated prices: Estimated prices in previous auctions have been as high as 6000 euros, suggesting there is potential for a high hammer price.

Taking all these factors into account, an estimated maximum purchase price could be around 5000 euros. This is based on the auction price history and the good condition of the coin. However, it is important to consider that the final price may vary depending on the competition in the auction and the interest from other buyers.

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

1. Current starting price: 19,000 euros.
2. Coin condition: 85 (ebc-), indicating good condition, although not the best.
3. Auction history:
- In 2017, the coin was auctioned with a starting price of 25,000 euros and sold for 33,000 euros.
- In 2021, although there was no starting price, it was estimated at 30,000 euros and sold for 32,000 euros, with a condition of 95, which is significantly better than the current one.

4. Average starting and final prices: The average starting price is 22,000 euros and the average final price is 32,500 euros.

Given that the current condition is lower than that of previous auctions, and considering that the current starting price is lower than previous starting and final prices, we can estimate a maximum purchase price.

Taking all these factors into account, a reasonable maximum purchase price could be between the average final price (32,500 euros) and the estimated price from previous auctions (30,000 euros).

Therefore, an estimated maximum purchase price could be around 30,000 to 32,000 euros. This reflects a balance between the current condition and the price history of the coin.

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

1. Coin Condition: The coin in question has a condition of 95 (S/C-), which indicates that it is in very good shape. 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 a similar condition (95), we can see that they have reached hammer prices of up to 900 euros in previous auctions. For example:
- In 2020, a coin with a condition of 95 was auctioned and reached a hammer price of 600 euros.
- In 2019, another coin with the same condition was also sold for 600 euros.

3. Average Hammer Price: The average hammer price for this coin is 436.04 euros, which provides an additional reference point.

4. Starting Price: The starting price of 450 euros is a good indicator of what is expected to be obtained in the auction.

Given that the condition is high and considering the previous hammer prices, an estimated maximum purchase price could be in the range of 600 to 900 euros. However, since the starting price is 450 euros, a reasonable maximum bid price could be approximately 700 euros. This allows for competition in the auction without exceeding the historical hammer prices for coins of similar condition.

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

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

2. Auction history:
- The average hammer price for this coin has been 11.6 euros.
- In previous auctions, hammer prices of up to 50 euros have been recorded for coins with the same condition (as in the auction on December 17, 2020).
- Most recent auctions with a condition of 100 have had hammer prices ranging between 10 and 20 euros.

3. Starting price and estimated prices:
- The current starting price is 6 euros, which is relatively low compared to previous hammer prices.
- The estimated price for this auction is 20 euros, suggesting that bidders are willing to pay more than the starting price.

4. Sales trends: Of the 58 times it has been auctioned, it has sold 44 times, indicating good demand.

Based on these factors, an estimated maximum purchase price could be in the range of 20 to 30 euros, considering that the highest recorded hammer price was 50 euros, but recent trends suggest that prices are closer to 20 euros. Therefore, a reasonable maximum purchase price could be 25 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 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 69.01 euros.
- Previous hammer prices for coins with a similar condition (95) have varied, but there are examples where they have sold for 90 euros or more, such as in the auction on 2020-12-17, where a coin with a condition of 100 was hammered at 90 euros.

3. Starting Price and Estimates:
- The current starting price is 60 euros, which is reasonable given the price history.
- The estimated price for this auction is 100 euros, suggesting that there are expectations for the coin to reach a higher price.

4. Sales Trends: The coin has been auctioned 94 times, with a high sales percentage (85 out of 94), indicating good demand.

Based on these factors, an estimated maximum purchase price could be between 90 and 110 euros, considering that the condition is high and there are precedents for sales in that range. Therefore, a reasonable maximum purchase price could be 100 euros.

To estimate a maximum purchase price for the coin in question, we can 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 translates to a higher price compared to coins with lower conditions.

2. Auction History: By observing previous hammer prices for coins with a similar condition (100 or close), we can see that the hammer price has varied. For example:
- In the auction on 2020-12-17, a coin with a condition of 100 was sold for 70 euros.
- In the auction on 2018-09-19, another coin with a condition of 100 was sold for 14 euros.
- In the most recent auction on 2023-01-18, it was sold for 45 euros.

3. Starting Price and Average Prices: The current starting price is 18 euros, and the average hammer price in the past has been 16.81 euros. However, given that the condition of this coin is high, it is reasonable to expect that the hammer price will be above average.

4. Auction Trends: Since there are 2 auctions scheduled in the coming days, this may increase competition and, therefore, the hammer price.

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 high and there is a history of hammer prices that supports this estimate. However, it is important to stay alert to the dynamics of the auction and any competition that may arise.

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 (S/C-), 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 has been 21.79 euros.
- In previous auctions, we have seen hammer prices that varied, but there are examples of sales reaching up to 130 euros (in an auction with a condition of 100).
- Most hammer prices for similar conditions (95) have been in the range of 20 to 30 euros.

3. Starting Price and Average Starting Price: The current starting price is 12 euros, and the average starting price is 12.25 euros. This suggests that the starting price is reasonable and not excessively high.

4. Recent Trends: In the most recent auctions, hammer prices for coins with a condition of 95 have been around 16 to 30 euros.

Based on these factors, an estimated maximum purchase price could be in the range of 30 to 40 euros, considering that the condition is high and that the price history shows there may be interest in paying more for coins in good condition. However, since the starting price is 12 euros, it is likely that the hammer price will not significantly exceed this range.

Therefore, a reasonable maximum purchase price could be 35 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 translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price in previous auctions is 16.13 euros.
- Hammer prices of up to 130 euros have been recorded for coins with similar condition (100), and hammer prices of 50 euros for coins with a condition of 95.
- The trend of hammer prices for coins with a condition of 95 has been in a range of 12 to 50 euros in previous auctions.

3. Starting Price: The starting price is 12 euros, which may influence the final price, as buyers often consider the starting price as an indicator of the coin's value.

4. Supply and Demand: The coin has been auctioned 87 times, with 59 sales, indicating moderate interest in the coin. The next auction may attract interested buyers, especially if the condition is high.

Taking these factors into account, an estimated maximum purchase price could be in the range of 30 to 50 euros, considering that the condition is high and there is a history of hammer prices that supports this estimate. However, since the starting price is 12 euros, it is likely that the final price will not significantly exceed this range unless there is active competition among bidders.

Therefore, a reasonable maximum purchase price could be 40 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 of 95 (EF+), indicating that it is in very good shape. This generally increases its value compared to coins in lower conditions.

2. Previous Prices:
- In 2018, the coin was auctioned with a starting price of 150 euros and sold for 220 euros, with a condition of 95.
- In 2021, it sold for 140 euros with a condition of 95.
- In 2022, it sold for 150 euros with a condition of 70, indicating that condition significantly affects the price.

3. Average Hammer Price: The average hammer price for this coin is 184 euros, providing a good reference for the expected value.

4. Current Starting Price: The current starting price is 75 euros, which is quite low compared to previous prices.

5. Sales Trends: The coin has been auctioned 6 times, of which it has sold 5 times, indicating good demand.

Given all this, an estimated maximum purchase price could be in the range of 180 to 220 euros, considering that the condition is high and that previous prices have been consistent in that range. However, since the starting price is 75 euros, it could be a good opportunity to acquire it at a lower price, but the maximum you might consider to not exceed the market value would be around 200 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. Auction history:
- The average hammer price for this coin has been 16.79 euros.
- In previous auctions, hammer prices have reached up to 75 euros (in December 2020) for coins with the same condition (95).
- Most auctions have had hammer prices ranging between 10 and 30 euros, depending on the condition.

3. Starting price and estimates:
- The current starting price is 15 euros, which is slightly higher than the average starting price of 9.41 euros.
- The estimated price for this auction is 25 euros, suggesting that there are expectations for the coin to sell at a higher price.

4. Recent trends: In the most recent auctions, hammer prices have been in the range of 15 to 40 euros for coins of similar condition.

Based on these factors, an estimated maximum purchase price could be in the range of 30 to 40 euros, considering that the condition is high and there is a history of hammer prices supporting this estimate. However, since the starting price is 15 euros, some bidders may choose not to exceed this price, which could influence the final outcome of the auction.

Therefore, a reasonable maximum purchase price could be 35 euros.

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

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

2. Auction history:
- The current starting price is 30 euros.
- The average hammer price in previous auctions for coins in similar condition (100) has been 65 euros (in the auction on 2020-12-17).
- In other auctions, hammer prices for coins in condition 95 have reached up to 44 euros, which also indicates that a coin in better condition can fetch higher prices.

3. Price trends:
- The average hammer price in previous auctions is 16.46 euros, but this includes coins in lower conditions. For coins in Uncirculated condition, the price can be significantly higher.
- The price trend in previous auctions shows that coins in Uncirculated condition have reached hammer prices of up to 65 euros.

4. Supply and demand: The coin will be auctioned in the coming days, which may increase competition and, therefore, the hammer price.

Taking all these factors into account, an estimated maximum purchase price for this coin could be around 65-70 euros, given that this is the highest price reached in previous auctions for coins in similar condition. However, it is important to consider that the final price may vary depending on the competition in the auction and the interest of collectors.

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

1. Condition: The coin has a condition of 75 (MBC), which indicates that it is in an acceptable state, but not of the highest quality. This can influence the price, as coins in better condition tend to reach higher prices.

2. Auction history:
- In the past, coins of the same reference with similar conditions (75 and 80) have been auctioned.
- Previous hammer prices have been 135 (in 2015) and 75 (in 2021) for conditions of 75 and 80, respectively.
- The 2022 auction shows a starting price of 60 and an estimated price of 100 for a coin with a condition of 100, indicating that the price can vary significantly depending on the condition.

3. Starting price and average prices:
- The current starting price is 110 euros, and the average hammer price in the past has been 105 euros. This suggests that the market is willing to pay close to this price, but there may be fluctuations depending on demand.

4. Auction trends: Given that there have been more auctions and successful sales in the past, this may indicate sustained interest in this coin, which could drive up its price.

Based on these factors, an estimated maximum purchase price could be in the range of 100 to 120 euros, considering that the condition is a limiting factor and that the starting price is 110 euros. Therefore, a reasonable maximum purchase price could be 120 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 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 has been 19.46 euros.
- In previous auctions, coins with a similar condition (95) have reached hammer prices that vary, but some examples are:
- 20 euros on 2022-09-14.
- 22 euros on 2020-12-14.
- 20 euros on 2018-10-16.
- The highest recorded auction for a coin in condition 100 was 80 euros, but that is an exceptional case.

3. Starting Price and Estimates:
- The current starting price is 12 euros, and the average starting price in the past has been 11.51 euros.
- The estimated price for this auction is 20 euros.

4. Sales Trends: The coin has been sold in 43 out of 54 auctions, indicating good demand.

Based on these factors, a reasonable maximum purchase price could be in the range of 25 to 30 euros, considering that the condition is high and that the price history shows similar coins have reached hammer prices in that range.

Therefore, an estimated maximum purchase price could be 30 euros.

Given that the coin has a conservation grade of 95 (S/C-), which is a very high conservation level, and considering that this is the first time it is being auctioned, the starting price of 1500 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, for coins with high conservation grades, collectors are often willing to pay a price above the starting bid, especially if demand is high.

Taking these factors into account, an estimated maximum purchase price could be between 1800 and 2200 euros, depending on the competition in the auction and the interest from collectors.

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

1. Starting price: 1500 euros.
2. Current condition: 100 (S/C), indicating that the coin is in excellent condition.
3. Auction history: The coin has been auctioned once before, with a hammer price of 1500 euros and an estimated price of 3000 euros. The condition of that coin was 95, which is lower than the current condition.

Since the condition of the coin being auctioned now is better (100 compared to 95), and considering that the previous hammer price was 1500 euros, it is reasonable to assume that the price could be higher in this auction.

However, the starting price is 1500 euros, and given that there has been prior interest (it has sold in the past and has not gone unsold), this suggests that there is a market for this coin.

Estimated maximum purchase price:
- Given that the previous hammer price was 1500 euros and the current condition is better, we could estimate that the price could increase.
- A reasonable increase could be in the range of 20-30% over the previous hammer price, considering the condition.

Therefore, an estimated maximum purchase price could be in the range of 1800 to 1950 euros. This reflects an increase due to the better condition and interest in the coin, but it also remains within a reasonable range considering the starting price and auction history.

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

1. Current starting price: 1200 euros.
2. Coin condition: 95 (S/C-), indicating good preservation.
3. Auction history: The coin has been auctioned once before, with an estimated price of 1500 euros and a hammer price of 600 euros. This suggests that, although the hammer price was low, the estimated price was significantly higher.
4. Average hammer price: 600 euros, which is considerably lower than the current starting price.

Given that the coin's condition is high (95) and considering that the starting price is 1200 euros, which is the same as the average starting price, we can infer that interest in the coin could be high, especially if it has sold well in the past.

However, the previous hammer price was 600 euros, indicating that the market may not be willing to pay much more than that unless there is a change in demand or perception of the coin's value.

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

Estimated maximum purchase price: 900 - 1200 euros.

This allows for some competition in the auction but also considers the hammer price history.
