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

1. Starting Price: 1500 euros.
2. Condition: The coin has a condition rating of 95 (S/C-), indicating that it is in very good shape, although not the best possible condition (which would be 110).
3. Auction History: The coin has been auctioned once before, with an estimated price of 2000 euros and a hammer price of 4800 euros. This suggests that there is significant interest in this coin, and that the hammer price can be considerably higher than the starting price.
4. Average Hammer Price: The average hammer price for this coin is 4800 euros, indicating that, in general, buyers are willing to pay much more than the starting price.

Given that the coin is in good condition and has shown high interest in previous auctions, a reasonable maximum purchase price could be slightly lower than the average hammer price, but still significant.

Estimated Maximum Purchase Price: It could be reasonable to consider a maximum purchase price in the range of 4000 to 4500 euros, given the auction history and the condition of the coin. This allows for some competition in the auction, while still remaining below the previous average hammer price.

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 95 (S/C-), indicating that it is in very good shape. This generally increases its value compared to coins with lower conditions.

2. Auction History:
- The average hammer price for similar coins in the past is 67.89 euros.
- The coin has been auctioned 24 times, of which it has sold 19 times, indicating good demand.
- Previous hammer prices for coins with a similar condition (95) have varied, but there are examples of auctions reaching up to 50 euros in recent sales.

3. Starting Price and Estimates:
- The current starting price is 12 euros, which is relatively low compared to the average hammer price.
- The estimated hammer price in previous auctions for coins with a condition of 95 has reached up to 30 euros or more.

Considering these factors, an estimated maximum purchase price could be in the range of 50 to 70 euros, given that the condition is high and there is a history of hammer prices supporting this estimate. However, since the starting price is 12 euros, buyers may be willing to bid more, especially if there is interest in the coin.

Therefore, a reasonable maximum purchase price could be between 60 and 70 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 similar coins has been 85.45 euros.
- In previous auctions, hammer prices have varied, with a maximum of 110 euros and a minimum of 70 euros for coins with similar conditions.

3. Starting price: The starting price is 60 euros, which may be a good indicator of the expected sale.

4. Price trends:
- The coin has been auctioned 14 times, of which 13 have sold. This suggests good demand.
- The last auction shows a hammer price of 85 euros, which aligns with the average hammer price.

Based on this data, an estimated maximum purchase price could be around 90-100 euros, considering that the condition is good and that the price history shows that coins in similar conditions have reached hammer prices of up to 110 euros.

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