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 coins with a similar condition (95) has been between 20 to 25 euros in several previous auctions.
- In the most recent auction, a coin with the same condition sold for 120 euros, indicating a potential for high demand.

3. Starting price and previous prices:
- The current starting price is 18 euros, which is reasonable given the history of starting and hammer prices.
- The average hammer price in the past has been 24.42 euros, suggesting that the hammer price could be in a similar range.

4. Auction trends: The coin has been auctioned 17 times, of which 12 have sold. This indicates a consistent interest in the coin, which may influence the price.

Based on these factors, an estimated maximum purchase price could be between 25 and 30 euros, considering that the condition is high and there is a price history that supports this estimate. However, given the interest in the coin and the highest recorded hammer price, a maximum purchase price of up to 35 euros could be reasonable if one seeks to secure the acquisition.

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 previous hammer prices, we can see that the coin has reached hammer prices of up to 5000 euros in past auctions, with an average hammer price of 4140 euros.

3. Starting price and estimates: The current starting price is 3000 euros, which is below the average hammer price. This suggests that there is potential for the hammer price to be higher.

4. Auction trends: The coin has been auctioned 13 times, of which 10 have been sold. This indicates a consistent interest in the coin, which may influence the hammer price.

5. Recent auction prices: In the most recent auctions, hammer prices have varied, but they have been in the range of 3200 to 4000 euros for coins of similar condition.

Taking all these factors into account, an estimated maximum purchase price could be around 4500 euros. This price reflects both the condition of the coin and the price trends in previous auctions.

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

1. Starting Price: 12,000 euros. This is the initial price of the auction.
2. Auction History: The coin has been auctioned 3 times in the past and has sold on all occasions, indicating a consistent interest in the coin.
3. Average Starting and Hammer Price: The average starting price is 14,666.67 euros and the average hammer price is 18,300 euros. This suggests that, in general, coins of this reference tend to sell for above the starting price.
4. Condition: The coin has a condition rating of 95 (S/C-), which is quite high and may positively influence its value.
5. Previous Prices: In previous auctions, the hammer prices have been 22,100 euros (2015) and 20,000 euros (2021), indicating that the value of the coin has been quite high in the past.

Given that the current starting price is 12,000 euros and considering the history of hammer prices, as well as the condition of the coin, an estimated maximum purchase price could be in the range of 18,000 to 22,000 euros. This is based on the fact that the most recent hammer price was 12,800 euros, but the interest and condition suggest it could reach a higher price.

Therefore, a reasonable estimated maximum purchase price could be 20,000 euros.

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 (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 26.38 euros.
- The last auction with a similar condition (95) had a hammer price that has not been specified, but the starting price was 15 euros and the estimated price was 25 euros.
- In previous auctions, coins with a condition of 100 have sold for up to 75 euros.

3. Starting price and estimates:
- The current starting price is 20 euros, which is a good starting point.
- The average starting price in the past has been 16.15 euros, suggesting that the current starting price is reasonable.

4. Sales trends: Out of the 19 times it has been auctioned, 14 have been sold, indicating good demand.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 40 to 60 euros. This is based on the good condition of the coin and the hammer price history in previous auctions. A price of 50 euros could be a reasonable target, as it falls in the middle of this range and reflects the quality of the coin.

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 90 (EF), indicating that it is in very good shape. This generally increases its value compared to coins with lower conditions.

2. Auction History:
- The coin has been auctioned 6 times in the past, of which it has sold 4 times. This suggests that there is interest in the coin.
- The average hammer price in previous auctions is 49 euros, which can serve as a good indicator of market value.

3. Previous Starting and Hammer Prices:
- In previous auctions, starting prices have varied, but the highest recorded hammer price is 135 euros (in 2014), although the condition of that coin is not specified.
- The most recent auction (2023) shows a hammer price of 20 euros for a coin with a condition of 100, indicating that the price can vary significantly based on condition.

4. Current Starting Price: The starting price is 40 euros, which is reasonable given the price history.

Based on these factors, an estimated maximum purchase price could be positioned between the average hammer price (49 euros) and a bit more, considering the good condition of the coin.

Therefore, a reasonable maximum purchase price could be 60 euros. This allows for some margin for competition in the auction, given that the condition is high and there is a history of interest in the coin.

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 quite good shape. This generally increases its value compared to coins in lower conditions.

2. Starting Price and Average Hammer Price: The starting price is 60 euros, and the average hammer price in previous auctions is 57.38 euros. This suggests that the starting price is reasonable and that, in general, coins of this reference tend to sell close to this price.

3. Sales History: The coin has been auctioned 26 times, of which 16 have resulted in sales. This indicates a consistent interest in the coin, which may influence its value.

4. Previous Prices: Looking at previous hammer prices, there are examples of prices that vary significantly, from 9 euros to 200 euros. However, the most recent and relevant prices are more indicative of the current value.

5. Market Trends: Given that the coin is in good condition and has a history of successful sales, it is reasonable to assume that it could reach a price above the starting price.

Taking all these factors into account, an estimated maximum purchase price could be between 80 and 100 euros. This is based on the good condition of the coin and the demonstrated interest in previous auctions. However, the final price will depend 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, we can analyze several factors:

1. Current Condition: The coin has a condition rating of 85 (ebc-), indicating that it is in quite good shape. This is important because coins in better condition tend to reach higher prices.

2. Auction History:
- The average hammer price for similar coins in condition 85 has been approximately 641.67 euros.
- In previous auctions, we have seen hammer prices that varied, but some have reached up to 1300 euros in exceptional cases.

3. Starting Price and Average Starting Price:
- The current starting price is 500 euros, which is slightly lower than the average starting price of 516.25 euros. This could indicate a good buying opportunity.

4. Sales Trends: The coin has been auctioned 21 times, of which 15 have been sold. This suggests that there is consistent interest in this coin, which may influence its price.

5. Previous Prices:
- In previous auctions, the highest hammer price for a coin with a similar condition has been 950 euros, which can serve as a reference point.

Taking all these factors into account, an estimated maximum purchase price could be around 800-900 euros. This is based on the hammer price history for coins in similar conditions and the demonstrated interest in previous auctions. However, since the starting price is 500 euros, it could be a good opportunity to acquire it at a lower price if competition is not high.

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 85 (ebc-), which indicates that it is in fairly good shape, but not the best possible condition. This can influence the price, as coins in better condition tend to fetch higher prices.

2. Auction History:
- It has been auctioned 6 times in the past, of which 3 have been successful sales.
- The average hammer price in previous auctions is 35.33 euros, indicating that, in general, buyers are willing to pay more than the starting price.

3. Starting and Hammer Prices:
- The current starting price is 9 euros, which is relatively low compared to the average hammer price of 35.33 euros.
- In previous auctions, hammer prices have varied, but there are examples where prices have reached 75 euros (in 2017).

4. Recent Trends: In the most recent auctions, hammer prices have been in the range of 15 to 16 euros for coins in superior conditions (such as condition 100).

Given all this, an estimated maximum purchase price could be set in a range between 35 and 50 euros, considering that the current condition is good, but not excellent, and that the starting price is low. This also takes into account the history of hammer prices in previous auctions.

Therefore, a reasonable maximum purchase price could be 45 euros.

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