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

1. Starting Price: 125 euros. This is the initial price of the auction.
2. Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in quite good shape. This generally increases its value compared to coins in lower condition.
3. Auction History: The coin has been auctioned once before, with a starting price of 90 euros and a hammer price of 130 euros. This suggests that there is interest in the coin and that it can reach competitive prices.
4. Average Hammer Price: 130 euros, which is the average price at which similar coins have sold in the past.
5. Average Starting Price: 107.5 euros, indicating that the current starting price (125 euros) is slightly higher than average, but not excessively so.

Given that the condition is good and there is a history of successful sales, an estimated maximum purchase price could be slightly higher than the previous hammer price, while also considering the current starting price.

Taking all these factors into account, an estimated maximum purchase price could be between 130 and 150 euros. This is based on the interest shown in the coin and its good condition. Therefore, a reasonable maximum price could be 145 euros.

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 80 (MS+), indicating that it is in relatively good shape. This can positively influence its price.

2. Historical Prices: By looking at previous auction prices for coins with similar conditions, we can see that prices have varied. For example:
- In 2023, a coin with a condition of 80 sold for 160 euros.
- In 2022, a coin with a condition of 80 sold for 130 euros.
- In 2020, a coin with a condition of 80 sold for 140 euros.

3. Average Auction Price: The average auction price for this coin is 169.36 euros, which is also a good indicator of the expected value.

4. Starting Price: The starting price is 150 euros, suggesting that the seller expects a reasonable price.

5. Recent Trends: In the most recent auctions, hammer prices have shown a trend of increasing, especially for coins in good condition.

Taking all these factors into account, an estimated maximum purchase price could be around 180-200 euros. This is based on the average auction price and recent trends, as well as the condition of the coin. However, it is important to remember 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 will consider several factors:

1. Current Condition: The coin has a condition rating of 80 (MS+), indicating that it is in relatively good shape. This can positively influence its value.

2. Previous Auction Prices:
- The average hammer price in previous auctions is 132.5 euros.
- In the most recent auction (2022-10-19), the coin was sold for 190 euros with a condition rating of 80.
- In other auctions, the hammer price has varied but has reached up to 220 euros in 2018.

3. Starting Price and Estimates:
- The current starting price is 140 euros, which is slightly higher than the average starting price of 103.25 euros.
- The estimated price for the current auction is 200 euros.

4. Sales Trends: The coin has been sold in 18 of the last 20 auctions, indicating good demand.

Based on these factors, a reasonable maximum purchase price could be in the range of 180 to 220 euros, considering that the condition is good and that it has reached similar prices in previous auctions.

Therefore, an estimated maximum purchase price could be 200 euros. This allows for a margin to compete in the auction without exceeding the market value observed in previous auctions.

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 can consider several factors based on the provided data:

1. Current Condition: The coin has a condition rating of 75 (MBC), indicating that it is in relatively good shape, but not among the highest qualities.

2. Auction History:
- The average hammer price for similar coins has been 139.59 euros.

- The estimated price for this auction is 125 euros, suggesting that bidders may be willing to pay more than the starting price.

4. Price Trends:
- In recent auctions, the hammer price has varied, but there have been examples where coins with similar conditions have reached hammer prices of 150 to 200 euros.

Based on these factors, an estimated maximum purchase price could be in the range of 150 to 200 euros, considering that the condition is an important factor and that interest in the coin may be high.

Therefore, a reasonable maximum purchase price could be 180 euros. This allows for some margin for competition in the auction, given the history of hammer prices and the condition of the coin.

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 85 (MS+/EF-), indicating that it is in relatively good shape. This suggests that its value could be in the upper range of previous auctions.

2. Previous Auction Prices: By observing the hammer prices of coins with a similar condition (85) in previous auctions, we find that:
- In the auction on 2022-10-19, a coin with a condition of 85 sold for 220 euros.
- In the auction on 2020-12-16, a coin with the same condition sold for 240 euros.
- In the auction on 2023-03-16, a coin with a condition of 95 sold for 270 euros, indicating that the value may increase with better condition.

3. Starting Price and Average Hammer Price: The current starting price is 150 euros, and the average hammer price in previous auctions is 152.31 euros. This suggests that the hammer price could be around this value, but given that the condition is good, it is reasonable to expect a higher price.

4. Market Trends: Since the coin has been auctioned 51 times and has a history of successful sales, this indicates a steady demand. Additionally, the fact that there have been no unsold coins in the past suggests that buyers are willing to pay for it.

Based on these factors, an estimated maximum purchase price for this coin could be between 220 and 250 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate. Therefore, a reasonable maximum purchase price could be 250 euros.

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 80 (MBC+), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price from previous auctions is 166.25 euros.
- The last auction with a similar condition (85) had a hammer price of 400 euros, indicating that there is a market willing to pay high prices for coins in good condition.
- Previous auctions with lower conditions (70-75) have had hammer prices ranging from 100 to 140 euros.

3. Starting Price: The current starting price is 150 euros, which is a good starting point, but given the history of hammer prices, it may be reasonable to expect the final price to be higher.

4. Market Trends: Since the coin has sold in all previous occasions and has had a hammer price exceeding the starting price, this suggests there is consistent interest in this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 200 to 250 euros. This is based on the history of hammer prices and the current condition of the coin. However, it is important to consider that bidder interest in the auction may influence the final price.

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 that will be auctioned, we can analyze the provided data:

1. Starting price: 175 euros.
2. Condition of the coin: 70 (MBC-), indicating an average condition.
3. Previous hammer prices: Previous hammer prices have varied, but there are some relevant data:
- In previous auctions with similar conditions (for example, 80 and 85), the hammer prices were 260 euros and 560 euros, respectively.
- The average hammer price in the past has been 257.56 euros.

4. Auction trends: The coin has been auctioned 11 times, of which it has sold 9 times. This indicates a consistent interest in the coin.

5. Average starting price: 156.25 euros, suggesting that the current starting price (175 euros) is slightly higher than the average, but not excessively so.

Given that the condition of the coin is 70 (MBC-), and considering the hammer prices of coins with similar conditions, an estimated maximum purchase price could be situated between the starting price and the average hammer price.

Estimated maximum purchase price:
We could consider a range between 250 and 300 euros, based on the average hammer price and the trend of previous auctions. A reasonable maximum price could be 280 euros. This is based on the expectation that the coin could reach a hammer price similar to that of previous auctions with comparable conditions.

2. Auction History:
- The average hammer price for similar coins in the past is 104.95 euros.
- Previous auctions of this coin have shown hammer prices that vary, but there are examples of sales reaching up to 370 euros for coins in similar or better conditions.

3. Starting Price and Average Starting Price:
- The current starting price is 40 euros, which is relatively low compared to the average hammer price.
- The average starting price of 53.87 euros also suggests that the current starting price is competitive.

4. Sales Trends: The coin has been sold in 68 out of 71 auctions, indicating high demand and a good sales history.

5. Comparison with Previous Prices:
- In previous auctions, coins with a condition rating of 80 have reached hammer prices that vary, but some examples show sales from 90 to 370 euros.

Based on these factors, an estimated maximum purchase price could be in the range of 120 to 150 euros, considering that the condition is good and that the hammer price history suggests potential for reaching higher prices at auctions. However, since the market can be volatile, it is advisable to keep an eye on the competition in the auction and adjust the bid accordingly.

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

1. Starting Price: 60 euros. This is the initial price of the auction.
2. Condition: The coin has a condition of 30 (BC+), indicating that it is not in very good shape. This may affect its value compared to coins in better condition.
3. Auction History: The coin has been auctioned once in the past, with a starting price of 80 euros and a hammer price of 120 euros. This suggests that, despite its condition, there is interest in the coin that could lead to a higher hammer price.
4. Average Starting and Hammer Prices: The average starting price is 70 euros and the average hammer price is 120 euros. This indicates that, in general, coins of this reference tend to sell for higher prices.

Given that the coin has a condition of 30, it is likely that its hammer price will not reach the historical maximum of 120 euros, but it could be in a lower range. Considering the starting price of 60 euros and the demonstrated interest in the previous auction, an estimated maximum purchase price could be between 80 and 100 euros.

Therefore, a reasonable estimated maximum purchase price for this coin could be 90 euros. This takes into account its condition and the historical interest in the coin.

Previous Hammer Prices: Looking at previous hammer prices for coins with a similar condition (80), we can see that they have reached hammer prices that vary, but some have reached 190 euros (in 2018) and 250 euros (in 2022). This suggests that there is significant potential for a high hammer price.

5. Recent Trends: In the most recent auction, a coin with a similar condition sold for 340 euros, indicating that the market may be on the rise.

Based on these factors, an estimated maximum purchase price could be in the range of 150 to 200 euros, considering that the condition is good and that the sales history supports a higher price. However, given the recent market behavior, a maximum purchase price of 200 euros could be a reasonable estimate.
