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 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 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.

2. Auction History:
- The average hammer price in previous auctions is 2037.15 euros.
- In past auctions, the coin has reached hammer prices that varied, but generally, the hammer prices have been in the range of 2000 to 3000 euros, depending on the condition and other factors.

3. Starting Price and Estimates:
- The current starting price is 1500 euros, which is a reasonable starting point.

- The coin has been sold in 21 out of 23 auctions, indicating good demand and a history of successful sales.

5. Comparison with Previous Prices:
- In previous auctions, coins with similar conditions have reached hammer prices of up to 3000 euros.

Based on these factors, an estimated maximum purchase price could be in the range of 2500 to 2800 euros, considering that condition is a key factor and that the average hammer price has been 2037.15 euros.

Therefore, a reasonable maximum purchase price could be 2800 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 95 (EF+), indicating that it is in very good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Auction History:
- The average hammer price for similar coins has been 80.33 euros.
- In previous auctions, hammer prices have varied, but some have reached up to 200 euros in similar conditions.
- The last auction for this coin had a starting price of 45 euros, with an estimated price of 75 euros.

3. Price Trends:
- The price trend appears to be increasing, especially for coins in good condition.
- 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.

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

4. Starting Price: The starting price is 250 euros, suggesting that the seller has high expectations for this auction.

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, let's consider several factors:

1. Current starting price: 5500 euros.
2. Coin condition: 100 (S/C), indicating it is in excellent condition.
3. Auction history:
- In 2016, the coin was auctioned with a starting price of 1500 euros and sold for 3800 euros.

4. Average hammer price: 3800 euros, which is an important data point for understanding market value.

5. Auction trends: The coin has seen an increase in its starting price at recent auctions, suggesting growing interest.

Given that the condition is excellent and considering the current starting price of 5500 euros, which is higher than previous hammer prices, we could estimate that the maximum purchase price could be in a range above the starting price, but not too far from the average hammer price.

Taking all these factors into account, an estimated maximum purchase price could be between 6000 and 7000 euros, given the growing interest and the excellent condition of the coin. This would allow a buyer to be willing to pay a bit more than the starting price, but it would also reflect the risk that the coin may not sell at the expected price.

4. Average hammer price: 4500 euros, which is a good indicator of market value.

Given that the current coin has a condition of 95, similar to the 2024 auction, but with a higher starting price, we can infer that the hammer price could be in a similar range or slightly higher than that of the previous auction.

Considering the starting price of 5500 euros and the auction price history, an estimated maximum purchase price could be between 6000 and 6500 euros, given that the condition is good and the interest in the coin seems to be solid.

Therefore, an estimated maximum purchase price could be 6500 euros.

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

3. Sales trends: Of the 9 times it has been auctioned, it has sold 4 times, indicating moderate interest in the coin.

4. Current starting price: The starting price is 6 euros, which is relatively low compared to the average starting price of previous auctions.

Given that the coin is in good condition and considering previous hammer prices, an estimated maximum purchase price could be in the range of 20 to 30 euros. This is based on the fact that the highest hammer price in the past was 24 euros and the average hammer price is 13.5 euros, but given the condition, it can be expected that the hammer price will be higher in this auction.

Therefore, an estimated maximum purchase price could be 25 euros.
