This is based on the fact that the highest hammer price in the past was 620 euros and that the current starting price is 400 euros.

Therefore, an estimated maximum purchase price for this coin could be 550 euros. This allows for some margin for competition in the auction, given that there is interest in the coin and its condition is favorable.

Given that the coin has a grade of 75 (MBC), indicating good quality, and considering that it is being auctioned for the first time, the starting price is set at 300 euros.

In this case, since there are no historical sales data for this coin, we can estimate a maximum purchase price based on the starting price and the grade.

Generally, in auctions, final prices can vary between 1.5 to 2 times the starting price for coins in good condition. Therefore, an estimated maximum purchase price could be between 450 and 600 euros.

However, since the starting price is 300 euros and there are no sales records, a more conservative estimated price could be around 450 euros.

Thus, the estimated maximum purchase price would be approximately 450 euros.

- The average hammer price is 326.67 euros, indicating that, on average, similar coins have reached prices close to this value.

4. Recent Trends: In the last auction, the hammer price was 260 euros, which could indicate a slight decrease in interest or in the value of the coin compared to previous auctions.

Taking all these factors into account, an estimated maximum purchase price could be in a range between the average hammer price (326.67 euros) and the highest price reached in the past (420 euros).

2. Current Starting Price and Previous Prices: The current starting price is 75 euros, and the average hammer price in previous auctions is 131.05 euros. This suggests that, in general, coins of this reference tend to sell for above their starting price.

3. Auction History: In the auction history, it is observed that coins with similar conditions have reached hammer prices that vary, but many are in the range of 110 to 140 euros. For example, in 2020, a coin with a condition of 80 was sold for 110 euros.

4. Recent Trends: In the most recent auctions, hammer prices have been in the range of 120 to 160 euros for similar conditions.

This is based on the hammer price history and the current condition of the coin. However, it is important to remember 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. Current Condition: The coin has a condition rating of 80 (MS+), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Previous Prices: By looking at previous auction prices, we can see that in the most recent auction (2023), the coin sold for 1800 euros, suggesting that there is significant interest in this coin in its current state.

3. Starting Price and Average Hammer Price: The current starting price is 1500 euros, and the average hammer price in previous auctions is 1230 euros. This indicates that the starting price is higher than the average hammer price, which may be an indicator that the seller expects greater interest in this auction.

4. Sales Trend: The coin has sold every time it has been auctioned, suggesting that there is consistent demand.

Based on these factors, an estimated maximum purchase price could be positioned in a range between the highest previous hammer price (1800 euros) and a bit more, considering the good condition and interest in the coin.

Therefore, an estimated maximum purchase price could be approximately 1900 to 2000 euros. This would allow for competitive bidding in the auction without exceeding a reasonable limit based on the sales history and current condition.

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

1. Starting price: 90 euros.
2. Average hammer price in the past: 160 euros.
3. Condition of the coin: 75 (MBC), which is quite a good condition.
4. Auction history: The coin has been auctioned once before and sold for 160 euros.

Given that the average hammer price in the past was 160 euros and considering that the condition is the same (75), it is reasonable to assume that the hammer price could be in a similar range.

Additionally, since there is an auction scheduled in the coming days and the coin has a history of successful sales, this could increase interest and competition among bidders.

Taking all these factors into account, an estimated maximum purchase price could be around 160-180 euros, as this reflects the previous hammer price and allows for a small margin for competition in the auction.

Therefore, an estimated maximum purchase price would be 180 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 75 (MBC), indicating that it is in quite good shape. This generally increases its value compared to coins with lower conditions.

2. Starting Price: The starting price is 110 euros, suggesting that the seller has high expectations for this auction.

3. Auction History: The coin has been auctioned once in the past, with a starting price of 30 euros and a hammer price of 30 euros. This indicates that, in the past, the coin did not have high demand, although the current starting price is significantly higher.

4. Average Hammer Price: The average hammer price in the past was 30 euros, suggesting that despite a higher starting price, the actual interest from buyers may be lower.

5. Auction Expectations: Since it will be auctioned again in the coming days, and considering that the starting price is 110 euros, it is possible that buyers may be willing to pay more than the previous average hammer price, but not necessarily the full starting price.

Taking all these factors into account, an estimated maximum purchase price could be positioned between the previous average hammer price and the current starting price. A reasonable range could be between 50 and 70 euros, considering that the condition is good and there is potential interest, but also that the auction history does not support a hammer price as high as the starting price.

Therefore, an estimated maximum purchase price could be 70 euros.

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

2. Current listing price and previous prices: The current listing price is 120 euros. In previous auctions, we have seen hammer prices that varied significantly, but some have reached prices above 100 euros, such as the hammer price of 103 euros in 2019.

3. Price trends: The average hammer price in previous auctions is 74.05 euros, but there are examples of sales that have exceeded 100 euros. This suggests that there is potential for the coin to sell at a higher price, especially considering its good condition.

4. Supply and demand: Since this coin has been auctioned 20 times and all have sold, this indicates good demand. Additionally, it will be auctioned once more in the coming days, which may influence competition and the final price.

Taking all these factors into account, an estimated maximum purchase price could be around 120-140 euros. This is based on the good condition of the coin and previous hammer prices that have exceeded 100 euros. However, it is important to consider that the final price will depend on the competition in the auction and the interest of collectors.
