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

1. Condition: The coin has a condition of 70 (VF-), indicating that it is in quite good shape. This generally suggests that the final price could be higher than the average for coins in worse conditions.

2. Auction History:
- It has been auctioned 6 times in the past, of which it has sold 3 times.
- The average starting price is 9.83 euros, and the average final price is 8.67 euros.
- The starting and final prices in previous auctions varied, but there are examples where the starting price has been as high as 18 euros and the estimated price reached 30 euros.

3. Price Trends:
- In previous auctions, final prices have ranged between 9 and 14 euros, with an estimated price of up to 30 euros in one previous auction.
- Given that the coin has a condition of 70, it is reasonable to assume that it could achieve a final price higher than average.

4. Estimation:
- Considering the current starting price of 1 euro, which is quite low compared to previous starting prices, and the history of final prices, a reasonable maximum purchase price could be in the range of 15 to 20 euros, as this aligns with previous final prices for coins in similar conditions.

Therefore, an estimated maximum purchase price for this coin could be 20 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 80 (MBC+), indicating that it is in relatively good shape. This suggests that its value should be above that of coins in worse conditions.

2. Auction History:
- The average hammer price for similar coins in the past is 20.13 euros.
- Previous hammer prices for coins with a similar condition (80) have varied, but there are examples of hammer prices in the range of 15 to 30 euros.
- The last auction with a condition of 80 had a hammer price of 20 euros.

3. Starting Price and Average Starting Price:
- The current starting price is 12 euros, which is quite low compared to the average starting price of 24.64 euros. This suggests that there is potential for the hammer price to be significantly higher.

4. Price Trends:
- In previous auctions, coins with a condition of 80 have reached hammer prices of up to 30 euros.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 25 to 30 euros, considering that the condition is good and that the price history suggests it could reach that level in an auction.

Therefore, a reasonable estimated maximum purchase price would be 30 euros.

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

1. Condition: The coin has a condition rating of 70 (VF-), indicating that it is in acceptable condition, but not among the best qualities. This affects the price, as coins in better condition tend to fetch higher prices.

2. Auction History:
- It has been auctioned 8 times in the past, of which it has sold 4 times. This suggests there is moderate interest in the coin.
- Previous hammer prices have varied, but the average hammer price in auctions where it sold is approximately 27 euros.
- In past auctions, the estimated price has ranged between 25 and 45 euros, but the highest recorded hammer price was 30 euros.

3. Starting Price and Average Hammer Price: The current starting price is 25 euros, and the average hammer price is 27 euros. This suggests that the market is willing to pay a little more than the starting price, but not much more.

4. Price Trends: Given that the estimated price in previous auctions has been up to 45 euros, but the highest hammer price has been 30 euros, it is reasonable to assume that interest in this coin has not increased significantly since then.

Based on these factors, an estimated maximum purchase price could be around 30-35 euros. This is based on the history of hammer prices and the condition of the coin. Therefore, a reasonable maximum purchase price could be 35 euros.

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

1. Current Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in quite good shape.

2. Auction History:
- The average hammer price for coins with a similar condition (80) has been approximately 44 euros in previous auctions.
- The hammer prices for coins with a condition of 80 have varied, with a range from 12 euros to 120 euros in past auctions.

3. Starting Price: The current starting price is 12 euros, which is relatively low compared to previous hammer prices.

4. Price Trends:
- In previous auctions, coins with a condition of 80 have had hammer prices ranging from 20 to 55 euros in the most recent auctions.
- The average hammer price of 38.5 euros also suggests that there is potential for the coin to reach a higher price.

Based on this data, an estimated maximum purchase price for this coin could be around 50-60 euros, considering that the condition is good and that the hammer price history supports this estimate. However, it is important to keep in mind that collector interest and competition in the auction can also 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 translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price in previous auctions for coins with a similar condition (75) has been approximately 29.88 euros.
- In past auctions, estimated prices for coins with a condition of 75 have ranged between 30 and 70 euros, with some hammer prices reaching up to 80 euros.

3. Starting Price: The current starting price is 40 euros, which is a good starting point.

4. Sales Trends: Of the 23 times it has been auctioned in the past, it has sold 8 times, indicating moderate interest in the coin.

5. Previous Prices: In the most recent auction, the hammer price was 80 euros, suggesting that there is potential to reach higher prices in the future.

Taking all these factors into account, an estimated maximum purchase price for this coin could be between 70 and 80 euros, given that the condition is good and there is a price history supporting this estimate. However, since the starting price is 40 euros, it may be wise to consider a more conservative purchase price, perhaps around 60-70 euros, depending on the competition in the auction.

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 has a condition rating of 70 (MBC-), indicating that it is in relatively good shape, but not of the highest quality (FDC).

2. Auction History:
- The average hammer price for similar coins in the past is 58.22 euros.
- The coin has been auctioned 77 times, of which it has sold 71 times, indicating good demand.
- Previous hammer prices for coins with a similar condition (70) have varied, but there are examples of auctions reaching up to 90 euros.

3. Starting and Hammer Prices:
- The current starting price is 18 euros, which is quite low compared to the average hammer price.
- In previous auctions, coins with a condition of 70 have had hammer prices ranging from 20 to 90 euros.

4. Recent Trends: In the most recent auctions, hammer prices for coins of similar condition have shown an increase, suggesting that demand may be growing.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 70 to 90 euros. This is based on the historical hammer prices for coins of similar condition and the trend of increasing prices. However, since the starting price is 18 euros, it is likely that the final hammer price will be closer to the lower end of this range, unless there is significant competition among 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 75 (MBC), which indicates that it is in quite good shape. This generally increases its value compared to coins in lower conditions.

2. Auction History:
- In the past, the coin has been auctioned 4 times, of which it has sold 2 times. This suggests that there is interest in the coin, although there is also a 50% no-sale rate, which may indicate that the starting price is sometimes too high.
- Previous starting and hammer prices are relevant. For example, in 2019, the starting price was 150 euros and the hammer price was 150 euros with a condition of 80. This suggests that the market is willing to pay close to the starting price under similar conditions.

3. Average Hammer Price: The average hammer price for this coin is 90 euros, which can serve as a benchmark.

4. Average Starting Price: The average starting price is 143.75 euros, indicating that sellers usually expect higher prices.

Given that the condition of the coin is 75, which is lower than the conditions of previous auctions (70 and 80), but still an acceptable state, we can estimate a maximum purchase price.

Considering all these factors, an estimated maximum purchase price could be positioned between the average hammer price and the average starting price, adjusted for condition.

Therefore, a reasonable maximum purchase price could be around 100-120 euros. This reflects interest in the coin, but also takes into account its condition and auction history.

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

For example, at the auction on December 15, 2020, a coin with a condition of 75 was sold for 30 euros, and on other occasions, it has reached up to 50 euros.

3. Average Hammer Price: The average hammer price for this coin is 44.76 euros, which also indicates that the market value is in that range.

4. Auction Trends: The coin has been auctioned 46 times, of which 33 have resulted in sales. This suggests that there is a consistent interest in this coin, which may increase its value.

5. Starting Price: The starting price is 12 euros, which is relatively low compared to previous hammer prices.

Based on these factors, an estimated maximum purchase price for the coin could be between 50 and 70 euros, considering that the condition is good and that the interest in the coin seems to be solid. However, since the starting price is 12 euros, it is likely that the hammer price will not significantly exceed the observed average range.

Therefore, a reasonable estimated maximum purchase price could be 60 euros.
