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

1. Current condition: The coin has a condition of 80 (MBC+), which is lower than the condition of 90 from the previous auction. This suggests that the value could be less than the estimated price of 238.33 euros from the previous auction.

2. Starting price: The starting price is 40 euros, indicating that the seller has a low expectation compared to the previous estimated price.

3. Auction history: The coin has been auctioned once in the past but did not sell. This may indicate that interest in the coin is not high, which could affect its price.

4. Current demand: The coin will be auctioned again in the coming days, which could generate a bit more interest, but the fact that it did not sell previously may limit the price.

Given that the current condition is lower than that of the previous auction and considering the starting price, an estimated maximum purchase price could be between 60 and 80 euros. This reflects an increase over the starting price but also takes into account the lower condition and the auction history.

Therefore, a reasonable maximum purchase price could be 70 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 70 (VF-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Previous Prices: Looking at previous auction prices for coins in similar condition (80), the hammer price has ranged between 810 and 1300 euros. A condition rating of 80 is higher than 70, so it is reasonable to expect that the hammer price for the coin in question will be lower than that of coins with a condition rating of 80.

3. Starting Price and Average Hammer Price: The current starting price is 1550 euros, which is significantly higher than the average hammer price of 1016.11 euros. This suggests that the seller has high expectations, but the market may not be willing to pay that much.

4. Auction Trends: The coin has been auctioned 9 times and has sold on all occasions, indicating consistent interest in the coin. However, the average hammer price is a good indicator of what buyers are willing to pay.

Taking all these factors into account, an estimated maximum purchase price could be around 1000-1100 euros. This is based on the average hammer price of coins in similar condition and the fact that the condition of this coin is lower than those that have sold in the past at higher prices.

Therefore, a reasonable maximum purchase price could be 1100 euros.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, including auction history and previous hammer prices.

1. Current Grade: The coin has a grade of 70 (MS-). This is an important factor, as coins in better condition tend to achieve higher prices.

2. Price History:
- The average hammer price for coins of similar grade (70) in the past has been approximately 1000 euros.
- In previous auctions, hammer prices for coins with a grade of 70 have ranged between 900 and 1300 euros, depending on demand and other factors.

3. Starting Price: The starting price of 1500 euros is higher than the historical average hammer price, suggesting that the seller has high expectations. However, the starting price does not always translate into a successful hammer price.

4. Recent Trends: In the most recent auctions, hammer prices have shown a trend of being in the range of 1000 to 1300 euros for coins of similar grade.

5. Estimation: Given that the coin's grade is 70 and considering the price history, a reasonable maximum purchase price could be in the range of 1100 to 1300 euros. This is based on the fact that buyers are often willing to pay a little more than the average hammer price to secure a coin in good condition.

Therefore, an estimated maximum purchase price for this coin could be 1300 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 85 (ebc-), which indicates that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Current and previous prices: The current starting price is 1450 euros, which is above the average starting price of 1005.36 euros and the average hammer price of 1233.79 euros. However, in previous auctions, the coin has reached hammer prices of up to 1600 euros under similar conditions.

3. Price trends: Looking at previous hammer prices, the coin has reached prices of up to 1500 euros in recent auctions, suggesting that there is growing interest in this coin.

4. Auction expectations: Since there are no auctions scheduled in the coming days, this could increase competition among bidders in the next auction, potentially driving up the price.

Taking all these factors into account, an estimated maximum purchase price could be around 1600-1700 euros, considering that this is a price that has been reached in the past and that the coin's condition is favorable. However, the starting price of 1450 euros also suggests that there may be room for competitive bidding.

To estimate a maximum purchase price for the coin in question, we can analyze 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. Previous Prices: By observing previous auction prices for coins with similar conditions, we can see that:
- In past auctions with a condition of 70, the hammer prices have ranged between 780 and 1900 euros.
- The general trend seems to be that coins with a condition of 70 have reached hammer prices around 850 to 1200 euros on several occasions.

3. Starting Price and Average Hammer Price: The current starting price is 1450 euros, which is higher than the average hammer price of 1299.43 euros. This suggests that the seller has high expectations, but it may also indicate that the market is willing to pay more.

4. Recent Trends: In the most recent auctions, hammer prices have been in the range of 1350 to 1601 euros for similar conditions.

Based on these factors, an estimated maximum purchase price could be in the range of 1300 to 1600 euros, considering that the starting price is 1450 euros and that the market has shown a willingness to pay prices in that range for coins of similar condition.

Therefore, an estimated maximum purchase price could be 1600 euros.

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

3. Current Starting Price: The starting price is 1450 euros, which is slightly lower than the previous average hammer price.

4. Price Trends: Observing the previous hammer prices, it seems that coins with a similar condition (70) have reached hammer prices of up to 1800 euros in the past.

5. Data-Based Estimation: Given that the condition of the coin is 70 and considering that there have been successful sales in the range of 1400 to 1800 euros, an estimated maximum purchase price could be positioned in the upper range of these prices.

Taking all these factors into account, an estimated maximum purchase price for this coin could be approximately 1800 euros. This is based on the history of hammer prices and the current condition of the coin.

Conclusion: An estimated maximum purchase price for this coin could be approximately 1400 euros. This is based on the analysis of previous hammer prices and the condition of the coin.
