5. Auction price analysis: Auction prices for coins with a condition of 80 have varied, but there are several examples that exceed 1000 euros. The average auction price (1021.87 euros) also suggests that the coin could sell for a price higher than the starting price.

6. Estimation of the maximum purchase price: Given that the average auction price is approximately 1021.87 euros and considering that the condition is good (80), a reasonable maximum purchase price could be in the range of 1100 to 1300 euros, taking into account that some auctions have reached up to 1400 euros in the past.

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-), indicating that it is in quite good shape. This generally translates to a higher value compared to coins with lower conditions.

2. Auction History:
- The average hammer price in previous auctions is 44.57 euros.
- The coin has been auctioned 35 times, of which it has sold 30 times, indicating good demand.
- In previous auctions, the hammer price has varied, but there are examples of sales that have reached up to 130 euros (in January 2023).

3. Starting Price and Estimates:
- The current starting price is 40 euros, which is slightly higher than the average starting price of 29.39 euros.
- The estimated price for this auction is 70 euros, suggesting expectations for the coin to reach a higher price.

4. Price Trends:
- Observing the hammer prices of coins with similar conditions, it seems that the price range can vary quite a bit, but higher prices have been seen in coins with conditions of 80 or more.

Based on these factors, an estimated maximum purchase price could be in the range of 70 to 130 euros, considering that the highest recorded hammer price was 130 euros. However, since the starting price is 40 euros and the average hammer price is 44.57 euros, a reasonable maximum purchase price could be approximately 80-100 euros. This would allow for competitive bidding in the auction without exceeding historical hammer prices for coins in similar conditions.

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

1. Condition: The coin has a condition of 95 (EF+), which indicates that it is in very good shape. This generally increases its value compared to coins with lower conditions.

2. Auction history: By looking at previous hammer prices for coins with similar conditions (95 and 100), we can see that the hammer prices have varied. For example:
- In 2020, a coin with a condition of 95 was auctioned for 30 euros.
- In 2020, another coin with a condition of 100 was auctioned for 110 euros.

4. Estimated price: In previous auctions, the estimated price for similar coins has ranged between 20 and 125 euros, depending on the condition and demand.

Given that the coin is in good condition (EF+) and considering the history of hammer prices, an estimated maximum purchase price could be set in a range between 70 and 110 euros. This is based on the fact that coins in similar conditions have reached hammer prices in that range.

Therefore, a reasonable estimated maximum purchase price for this coin could be 100 euros.

Based on these factors, an estimated maximum purchase price could be in the range of 70 to 90 euros, considering that the condition is high and that interest in the coin seems to be maintained. A price of 90 euros could be a reasonable target, given that a hammer price of 150 euros has been reached in the past for a higher condition.

Based on these factors, an estimated maximum purchase price could be in the range of 80 to 120 euros. This is because, although the starting price is 60 euros, the condition of the coin and the price history suggest that there could be enough interest for the hammer price to exceed the starting price, especially if there are several interested bidders.

Therefore, a reasonable estimated maximum purchase price could be 100 euros.
