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

1. Current starting price: 250 euros.
2. Average starting price in previous auctions: 116.23 euros.
3. Average hammer price in previous auctions: 173.05 euros.
4. Auction history: The coin has been auctioned 24 times, of which it has sold 20 times, indicating a good sell-through rate.
5. Previous hammer prices: There are several hammer prices that exceed 200 euros, especially in high grades (100 and 95).

Since there is no information about the condition of the current coin, it is difficult to make an accurate estimate. However, considering that in previous auctions hammer prices have reached up to 360 euros and that the current starting price is 250 euros, we can infer that interest in this coin may be high.

### Maximum purchase price estimation:
- Based on the highest hammer price: 360 euros.
- Based on the current starting price: 250 euros.
- Considering the average hammer price: 173.05 euros.

Given that the starting price is 250 euros and considering the interest in the coin, a reasonable maximum purchase price could be in the range of 300 to 360 euros, depending on the competition in the auction and the condition of the coin.

Estimated maximum purchase price: 350 euros.

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

1. Starting Price: The starting price is 120 euros.
2. Auction History: The coin has been auctioned 17 times, of which it has sold 14 times. This indicates good demand.
3. Previous Prices:
- The average hammer price in previous auctions is 124.36 euros.
- The highest hammer prices in previous auctions have been 190 euros (in 2019) and 140 euros (in 2017).
4. Condition: There is no information about the current condition of the coin, which may affect its value. However, in previous auctions, some coins of similar condition have reached hammer prices of up to 190 euros.

Given that the average hammer price is 124.36 euros and considering that there are previous auctions with higher hammer prices, an estimated maximum purchase price could be in a range between the average hammer price and the highest price observed.

Therefore, an estimated maximum purchase price could be approximately 180 euros. This is based on the trend of previous prices and the demand observed in past auctions.

To estimate a maximum purchase price for the coin in question, we can 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 similar coins in the past is 89.33 euros.
- The last auction of a coin with a similar condition (85) had a hammer price of 220 euros in 2018, suggesting that there is a market willing to pay higher prices for coins in good condition.

3. Starting Price and Average Starting Price:
- The current starting price is 120 euros, which is higher than the average starting price of 58.75 euros. This may indicate that the seller has higher expectations due to the coin's condition.

4. Sales Trends: The coin has been auctioned 17 times, of which 15 have sold. This suggests that there is consistent interest in this coin, which may influence the price.

5. Comparison with Previous Prices:
- Previous hammer prices for coins with similar conditions (80-85) have varied, but the highest recorded price was 220 euros.

Based on these factors, an estimated maximum purchase price could be in the range of 150 to 200 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate. However, given the starting price of 120 euros, it may be reasonable to consider a maximum purchase price around 180 euros, which is a midpoint between the starting price and the higher hammer prices observed in the past.
