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-), indicating that it is in fairly good shape, but not the best possible condition.

2. Previous Prices: By looking at previous auction prices for coins with similar conditions (85 and 90), we can see that auction prices have varied, but generally, coins in condition 85 have reached auction prices ranging from 300 to 400 euros.

3. Starting Price and Average Hammer Price: The current starting price is 350 euros, and the average hammer price in the past has been approximately 301.26 euros. This suggests that the starting price is reasonable and could attract bidders.

4. Recent Trends: In the most recent auctions, hammer prices for coins in similar conditions have been in the range of 400 euros, especially for coins that have been successfully auctioned.

5. Competition in the Auction: Given that there are 3 similar coins that will be auctioned in the coming days, this could influence demand and, therefore, the final price.

Based on these factors, an estimated maximum purchase price for this coin could be around 400-450 euros. This range considers the possibility that bidders may be willing to pay a little more for a coin in good condition and with a favorable auction price history.

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

1. Coin Condition: The coin to be auctioned has a condition 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. Previous Auction Prices: By observing the hammer prices of coins with a similar condition (95) in previous auctions, we can see that the hammer prices have varied but have reached figures close to 400 euros on several occasions. For example, in the auction on 2023-03-16, a coin with a condition of 95 was sold for 445 euros.

3. Average Hammer Price: The average hammer price for this coin is 301.26 euros, but given the high condition, it is reasonable to expect that the hammer price will be above this average.

4. Starting Price: The starting price of 400 euros is a good indicator of what is expected to be obtained in the auction. However, since the starting price does not always translate into the final hammer price, it is important to consider the price history.

5. Recent Trends: In the most recent auctions, hammer prices for coins of similar condition have been in the range of 400 to 500 euros.

Based on these factors, an estimated maximum purchase price for this coin could be between 450 and 500 euros, considering that the condition is high and there is a recent trend for hammer prices to exceed 400 euros.

Therefore, a reasonable estimated maximum purchase price would be approximately 480 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 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 287 euros.
- The coin has been auctioned 29 times, of which it has sold 26 times, indicating good demand.
- In recent auctions, hammer prices have varied, but there are examples of sales exceeding 200 euros.

3. Starting Prices and Estimates:
- The current starting price is 150 euros, which is reasonable given the history of starting and hammer prices.
- The estimated price for this auction is 150 euros, suggesting that auctioneers expect moderate interest.

4. Comparison with Previous Prices:
- In previous auctions, coins with similar conditions have reached hammer prices ranging from 90 to 600 euros, depending on the condition and demand at that time.

5. Recent Trends:
- In the most recent auctions, hammer prices have shown an increase, which could indicate a rising trend in interest for this coin.

Based on these factors, an estimated maximum purchase price could be around 300 euros. This is based on the history of hammer prices and the current condition of the coin, as well as the price trend in recent auctions. However, it is important to note that the final price may vary depending on competition in the auction and the interest of other buyers.

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

1. Current Condition: The coin has a condition of 30 (BC+), which indicates that it is not in very good shape. This generally reduces its value compared to coins in better condition.

2. Historical Prices: By looking at previous auction prices, we can see that coins of this reference have had a fairly wide price range. For example:
- In 2022, a coin with a condition of 80 was auctioned for 400 euros.
- In 2021, a coin with a condition of 30 was auctioned for 150 euros.
- In 2020, a coin with a condition of 70 was auctioned for 130 euros.

3. Starting Price and Average Hammer Price: The current starting price is 125 euros, and the average hammer price in the past has been 267.48 euros. This suggests that there is potential for an increase in the hammer price.

4. Recent Trends: Recent auctions have shown high hammer prices, even for coins with similar conditions.

Given all this, and considering that the condition of the coin is a limiting factor, an estimated maximum purchase price could be in the range of 150 to 200 euros. This is based on the fact that, although the condition is not optimal, the interest in the coin and previous hammer prices suggest that it could reach a reasonable price at auction.

Therefore, an estimated maximum purchase price could be 200 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 80 (MBC+), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Previous Auction Prices: By looking at the hammer prices of coins with similar conditions (70-85), we can see that the hammer prices have varied, but generally, they have been in a range of 125 to 340 euros.

3. Average Hammer Price: The average hammer price for this coin is 246.75 euros, which provides a good reference point.

4. Starting Price: The starting price of 225 euros is an indicator of what is expected to be obtained at the auction, but it does not necessarily reflect the final hammer price.

5. Recent Trends: In the most recent auctions, we have seen hammer prices exceeding the starting price, especially for coins in good condition. For example, in the auction on 2023-03-22, a coin with a condition of 80 was hammered at 340 euros.

Taking all these factors into account, an estimated maximum purchase price for this coin could be around 300-350 euros. This is based on the trend of hammer prices for coins of similar condition and the interest that this particular coin may generate.

3. Auction History: The coin has been auctioned 38 times, of which it has sold 34 times. This indicates good demand and sustained interest in the coin.

4. Previous Prices: By looking at previous hammer prices for coins with similar conditions, we can see that they have reached hammer prices that varied, but some have exceeded 200 euros, especially in higher conditions.

5. Recent Trends: In the most recent auctions, hammer prices have been quite high, with some reaching up to 650 euros in similar conditions.

Given all this, an estimated maximum purchase price could be in the range of 250 to 300 euros, considering that the condition is good and that interest in the coin seems to be high. This also takes into account the starting price and the history of hammer prices.

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. Current Condition: The coin has a condition rating of 75 (MBC), indicating that it is in fairly good shape, but not the best possible condition.

2. Auction History:
- The average hammer price for this coin in the past is 242 euros.
- In previous auctions, hammer prices have varied, with a maximum of 900 euros in a recent auction, although this may be an exceptional case.
- Most hammer prices for similar conditions (75) have been in the range of 170 to 280 euros.

3. Starting Price: The current starting price is 250 euros, suggesting that the seller has expectations for a hammer price in that range.

4. Market Trends: Given that the coin has been auctioned 29 times and has had a good sales percentage (26 out of 29), this indicates a consistent interest in the coin.

Based on these factors, an estimated maximum purchase price could be in the range of 280 to 320 euros, considering that the average hammer price is 242 euros and there is potential for the price to rise due to demand and the coin's condition. However, it is important to keep in mind that the final price will depend on the competition in the auction and the willingness of other bidders.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data:

1. Current starting price: 200 euros.
2. Current grade: 70 (MBC-), which is an acceptable grade, but not excellent.
3. Auction history:
- In the March 2023 auction, the coin started at 200 euros and sold for 400 euros with a grade of 90.
- In the May 2024 auction, it started at 250 euros and sold for 300 euros with a grade of 70.
- In the September 2024 auction, it started at 250 euros with an estimated price of 350 euros and a grade of 75.

4. Average hammer price: 350 euros, indicating that, in general, coins of this reference tend to sell for a price higher than the starting price.

5. Trends: The coin had a higher hammer price in the March 2023 auction, suggesting that there is significant interest in this reference, especially in better conditions.

Given that the current grade of the coin is 70, which is lower than that of the March 2023 auction (90), but similar to that of May 2024 (70), we can infer that the hammer price could be in a lower range than 400 euros, but it could still be competitive.

Estimation of the maximum purchase price:
- Considering the average hammer price of 350 euros and the grade of 70, a reasonable maximum purchase price could be between 250 and 300 euros, given that the starting price is 200 euros and there is interest in the coin.

Therefore, an estimated maximum purchase price could be 300 euros.

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

1. Starting price: 225 euros.
2. Average auction price in the past: 420 euros.
3. Condition of the coin: 70 (MBC-), which indicates good preservation, although it is not the best.
4. Auction history: It has been auctioned once before, and it sold for 420 euros.

Given that the average auction price in the past has been 420 euros and the coin has a condition of 70, which is quite good, we can infer that interest in this coin could be high.

Considering that the starting price is 225 euros and the average auction price has been 420 euros, an estimated maximum purchase price could be set within a range between the starting price and the average auction price.

A reasonable approach would be to establish a maximum purchase price that does not exceed the average auction price but also takes into account the starting price. Since the starting price is 225 euros, a maximum purchase price could be slightly higher than this, but not as high as the average auction price.

Therefore, an estimated maximum purchase price could be around 350 euros. This allows for a profit margin for the seller and remains within a reasonable range based on the auction history.
