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 85 (ebc-), indicating that it is in quite good shape. This is important because coins in better condition tend to reach higher prices.

2. Auction History:
- The average hammer price for similar coins in condition 85 has been approximately 641.67 euros.
- In previous auctions, we have seen hammer prices that varied, but some have reached up to 1300 euros in exceptional cases.

3. Starting Price and Average Starting Price:
- The current starting price is 500 euros, which is slightly lower than the average starting price of 516.25 euros. This could indicate a good buying opportunity.

4. Sales Trends: The coin has been auctioned 21 times, of which 15 have been sold. This suggests that there is consistent interest in this coin, which may influence its price.

5. Previous Prices:
- In previous auctions, the highest hammer price for a coin with a similar condition has been 950 euros, which can serve as a reference point.

Taking all these factors into account, an estimated maximum purchase price could be around 800-900 euros. This is based on the hammer price history for coins in similar conditions and the demonstrated interest in previous auctions. However, since the starting price is 500 euros, it could be a good opportunity to acquire it at a lower price if competition is not high.

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 85 (ebc-), which indicates that it is in fairly good shape, but not the best possible condition. This can influence the price, as coins in better condition tend to fetch higher prices.

2. Auction History:
- It has been auctioned 6 times in the past, of which 3 have been successful sales.
- The average hammer price in previous auctions is 35.33 euros, indicating that, in general, buyers are willing to pay more than the starting price.

3. Starting and Hammer Prices:
- The current starting price is 9 euros, which is relatively low compared to the average hammer price of 35.33 euros.
- In previous auctions, hammer prices have varied, but there are examples where prices have reached 75 euros (in 2017).

4. Recent Trends: In the most recent auctions, hammer prices have been in the range of 15 to 16 euros for coins in superior conditions (such as condition 100).

Given all this, an estimated maximum purchase price could be set in a range between 35 and 50 euros, considering that the current condition is good, but not excellent, and that the starting price is low. This also takes into account the history of hammer prices in previous auctions.

Therefore, a reasonable maximum purchase price could be 45 euros.

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

2. Starting price: The starting price is 1300 euros, which sets a baseline for the auction.

3. Price history: By observing previous hammer prices for coins with similar conditions (95 and 100), we can see that hammer prices have varied. For example:
- In previous auctions, coins with a condition of 95 have reached hammer prices of up to 335 euros (in 2014) and 300 euros (in 2022).
- Coins with a condition of 100 have reached hammer prices of up to 1900 euros (in 2022).

4. Price trends: The average hammer price for similar coins is 684.3 euros, suggesting that the hammer price may be considerably lower than the starting price in some cases.

5. Supply and demand: The coin has been auctioned 31 times in the past, with 22 sales, indicating moderate interest in the coin. However, the fact that there have been 9 occasions where it did not sell may indicate that the starting price is an important factor.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 800 to 1200 euros, depending on the competition in the auction and the interest of other bidders. Given that the starting price is 1300 euros, bidders may be willing to pay a little more, but it is likely that the hammer price will not significantly exceed the starting price, especially if there are other attractive lots in the same auction.

Therefore, a reasonable maximum purchase price could be 1000 euros.
