To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the previous auction prices and the conditions of the auctioned coins.

1. Starting price: 350 euros.
2. Times it has been auctioned in the past: 92.
3. Times it has sold in the past: 84.
4. Average hammer price: 167.6 euros.
5. Previous prices for this coin: The highest hammer prices have been 2000 euros (in 2019) and 370 euros (in 2019), with other hammer prices ranging from 80 to 625 euros in different auctions.

Since there is no information about the condition of the current coin, it is difficult to make an accurate estimate. However, we can observe that:

- Coins with higher conditions (95) have reached significantly higher hammer prices (up to 2000 euros).
- The majority of hammer prices are in the range of 80 to 370 euros, with an average of 167.6 euros.

Given that the starting price is 350 euros, which is relatively high compared to the average hammer price, and considering that there is no information on the condition of the coin, an estimated maximum purchase price could be slightly lower than the starting price, given the risk of not reaching that value at auction.

Estimated maximum purchase price: 300 euros.

This price reflects a balance between the starting price and previous hammer prices, taking into account the lack of information about the current condition.

### Conclusion:
An estimated maximum purchase price for this coin could be 600 euros. This price considers the auction history, the current starting price, and the possibility that the coin is in good condition, although it is not specified.

To estimate a maximum purchase price for the coin that will be auctioned, we can analyze the provided data. Here are some key points to consider:

1. Starting price: 300 euros.
2. Average hammer price: 317.16 euros.
3. Hammer price history: Previous hammer prices for similar coins have varied, with some reaching up to 550 euros in recent auctions.
4. Condition: There is no information about the condition of this coin, which may affect its value. However, most coins in the history have conditions between 80 and 100, suggesting that the coin could be in a similar range.

Given that the average hammer price is 317.16 euros and considering that some similar coins have reached higher hammer prices, an estimated maximum purchase price could be in the range of 400 to 450 euros. This is based on the fact that the hammer price can be higher than the average price, especially if the coin is in good condition or if there is significant interest in the auction.

Therefore, an estimated maximum purchase price could be 450 euros.

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-), 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 for this coin in the past is 529 euros.
- In recent auctions, we have seen hammer prices that vary significantly, ranging from 220 euros to 2800 euros, depending on the condition and demand at that time.
- In particular, at the March 2023 auction, the coin was hammered at 2800 euros, suggesting that there is significant interest in high-condition coins.

3. Starting Price and Average Starting Price:
- The current starting price is 500 euros, which is above the average starting price of 285.5 euros. This may indicate that the seller is confident that the coin will reach a higher price.

4. Recent Trends: In the most recent auctions, hammer prices have been quite high, suggesting that the market is willing to pay more for coins in good condition.

Based on these factors, an estimated maximum purchase price could be in the range of 800 to 1200 euros. This range takes into account the good condition of the coin, market interest, and previous hammer prices. However, given the history of high prices, it is possible that a buyer may be willing to pay even more if there is competition in the auction.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the previous auction prices and the conditions of the auctioned coins.

1. Current starting price: 500 euros.
2. Average hammer price: 225.78 euros.
3. Hammer price history:
- The coin has had hammer prices that vary significantly, ranging from 15 euros to 850 euros in previous auctions.
- The conditions of the auctioned coins in the past that have higher hammer prices (such as 850 euros) have a condition rating of 95, indicating they are of high quality.

4. Condition of the current coin: No information is provided about the condition of the coin to be auctioned, making the estimation more complicated. However, since the starting price is 500 euros, it is reasonable to assume that the coin has a condition rating that could be in the medium-high range.

5. Price trends:
- In previous auctions, hammer prices have been significantly lower than the starting prices in many cases, suggesting that buyers may not be willing to pay the full starting price.
- However, there are examples of coins that have sold for much higher prices, indicating that there is potential for a high hammer price if the coin is of high quality.

### Estimation of the maximum purchase price:
Given that the starting price is 500 euros and considering the hammer price history, a reasonable maximum purchase price could be in the range of 600 to 700 euros, assuming that the coin has an acceptable condition and there is interest in the auction.

Therefore, an estimated maximum purchase price could be approximately 650 euros. This allows for a margin for competition in the auction, but it is also based on the trend of previous hammer prices.
