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 70 (VF-), which indicates that it is in relatively good shape, but not of the highest quality (UNC).

2. Historical Prices: By looking at previous auction prices for coins with a similar condition (70), we can see that they have varied. For example:
- In past auctions, coins with a condition of 70 have reached hammer prices of 30 to 60 euros.
- The average hammer price for coins of similar condition seems to be around 30-50 euros.

3. Starting Price and Average Hammer Price: The current starting price is 18 euros, and the average hammer price for this coin in the past has been 104.05 euros. However, since the starting price is significantly lower, this may indicate that the market is adjusting expectations.

4. Recent Trends: In the most recent auctions, hammer prices for coins of similar condition have shown a range of 30 to 60 euros, suggesting that interest in coins in this state may be increasing.

Based on these factors, an estimated maximum purchase price for this coin could be between 50 and 70 euros, considering that the condition is an important factor and that interest in VF- quality coins may vary.

Therefore, a reasonable maximum purchase price could be 70 euros.

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

1. Condition of the coin: The coin has a condition rating of 85 (ebc-), which indicates that it is in fairly good shape, but not the best possible condition.

2. Previous prices: By looking at the auction prices of coins with similar conditions (85 and 90), we can see that the auction prices have varied. For example, in previous auctions, coins with a condition of 90 have reached auction prices of up to 130 euros, while those with a condition of 85 have had auction prices ranging between 50 and 90 euros.

3. Average auction price: The average auction price for this coin is 69.25 euros, which gives us a good reference point.

4. Recent trends: In the most recent auctions, the auction prices have shown an increase, especially for coins in good condition.

5. Starting price: The starting price is 18 euros, which suggests that there is considerable room for the final price to be higher.

Based on these factors, an estimated maximum purchase price for this coin could be between 80 and 100 euros, considering that the condition is good and there is an upward trend in auction prices in recent sales.

Therefore, a reasonable maximum purchase price could be 100 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 of 95 (EF+), indicating that it is in very good shape. This generally translates to a higher price compared to coins in lower condition.

2. Previous Prices:
- In the November 2022 auction, a coin with the same condition (95) was estimated at 40 euros and did not sell, suggesting that the final price could have been higher if there had been interest.
- In the February 2023 auction, the same condition was estimated at 30 euros and sold for 26 euros, indicating that interest may have slightly decreased.
- In the December 2024 auction, a coin with a condition of 90 was estimated at 50 euros and sold for 30 euros, which also suggests that the price may vary depending on demand.

3. Average Hammer Price: The average hammer price for similar coins is 36.67 euros, which can serve as a good indicator of market value.

4. Starting Price and Average Starting Price: The current starting price is 18 euros, which is relatively low compared to previous hammer prices. The average starting price is 25.14 euros.

Considering all these factors, an estimated maximum purchase price could be in the range of 40 to 50 euros, given that the condition is high and there is a history of hammer prices suggesting interest in that range. However, since interest may fluctuate, a price of 45 euros could be a reasonable target for a maximum bid.

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 indicates that it is in relatively good shape, but not among the highest quality.

2. Auction History:
- The average hammer price for coins of similar condition (70) in the past has been approximately 35-50 euros, based on previous auction hammer prices.
- In past auctions, coins with a condition of 70 have reached hammer prices of up to 110 euros (as seen in the auction on 2020-12-16).

3. Starting Price and Average Starting Price:
- The current starting price is 18 euros, which is quite low compared to the average starting price of 52.47 euros. This suggests that there is potential for the hammer price to be significantly higher.

4. Recent Trends:
- In the most recent auctions, the hammer price has varied, but there are examples where similar coins have reached hammer prices of 50-70 euros.

5. Data-Based Estimation:
- Given that the coin has a condition of 70 and considering the history of hammer prices, an estimated maximum purchase price could be between 50 and 80 euros. This is based on the fact that the hammer price can be higher than the average hammer price due to demand in the auction.

Conclusion: An estimated maximum purchase price for this coin could be 70 euros. This reflects a balance between the condition, price history, and market trend.
