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 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: By observing previous hammer prices for coins with similar conditions (around 80-85), we can see that hammer prices have varied. For example:
- In 2019, a coin with a condition of 85 was auctioned for 195 euros.
- In 2020, a coin with a condition of 80 was auctioned for 160 euros.
- In 2021, a coin with a condition of 85 was auctioned for 250 euros.

3. Starting Price and Average Hammer Price: The current starting price is 250 euros, and the average hammer price for similar coins is 207.5 euros. This suggests that the starting price is reasonable, but it also indicates that there may be room for the hammer price to be higher if there is interest.

4. Auction Trends: The coin has been auctioned 40 times in the past, with an 87.5% sell-through rate (35 out of 40). This indicates consistent interest in the coin, which may influence the hammer price.

5. Recent Hammer Prices: In the most recent auctions, hammer prices have been quite high, suggesting that interest in this coin may be increasing.

Based on these factors, an estimated maximum purchase price could be in the range of 250 to 300 euros, considering that the starting price is 250 euros and there are precedents for higher hammer prices for coins in similar conditions. However, given the interest and condition, a hammer price of up to 300 euros could be reasonable if there is competition in the auction.

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

1. Current Condition: The coin has a condition rating of 75 (MBC), indicating a medium-good quality. This suggests that its value should be in an intermediate range, but not at the highest level.

2. Auction History:
- The average hammer price in previous auctions is 294.47 euros.
- The coin has been auctioned 20 times, of which it has sold 17 times, indicating good demand.
- Previous hammer prices for coins with similar condition (75) have varied, but there are examples of auctions reaching up to 375 euros.

3. Starting Price and Estimates:
- The current starting price is 250 euros, which is a reasonable starting point.
- The estimated hammer price for this auction is 350 euros, suggesting that bidders are willing to pay more than the starting price.

4. Recent Trends: In the most recent auctions, hammer prices have been around 200-300 euros for similar conditions, but there are also examples of higher hammer prices.

Based on these factors, an estimated maximum purchase price could be around 350-400 euros, considering that the coin is in good condition and has shown a hammer price history that supports this figure. However, since the market can be volatile, it is advisable to keep an eye on the competition in the auction.

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 (MBC+/EBC-), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Current Starting Price and Previous Prices: The current starting price is 90 euros. In previous auctions, the average hammer price has been 70.03 euros, suggesting that the market has valued this coin at a range lower than the current starting price.

3. Historical Trends: Looking at the hammer prices from previous auctions, there are examples of similar coins that have sold for prices that varied significantly. For instance, in 2018, a coin with a condition of 95 sold for 300 euros, while others with a condition of 70-80 sold for between 40 and 75 euros.

4. Supply and Demand: The coin has been auctioned 91 times, with 82 sales, indicating good demand. However, there are 2 auctions scheduled in the coming days, which could affect competition and the final price.

5. Estimated Maximum Price: Given that the condition is relatively high and considering the starting price and previous hammer prices, a reasonable maximum purchase price could be in the range of 100 to 120 euros. This is based on the idea that collectors might be willing to pay a bit more for a coin in good condition, but also taking into account that the average hammer price has been lower than the starting price.

Therefore, an estimated maximum purchase price for this coin could be 110 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 of 85 (ebc-), which indicates 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 139.3 euros.
- The most recent auction (2023) had a hammer price of 150 euros for a coin with a condition of 75, which is lower than the current condition of 85.
- In 2018, a coin with a condition of 85 was sold for 360 euros, indicating significant potential for high prices for coins in good condition.

3. Starting Price and Average Starting Price: The current starting price is 90 euros, and the average starting price in the past has been 67.27 euros. This suggests that the current starting price is reasonable and could attract bidders.

4. Demand and Supply: Since there have been no unsold coins of this reference in the past, this indicates good demand.

Based on these factors, an estimated maximum purchase price could be in the range of 150 to 200 euros, considering that the condition is better than in recent auctions and that there is a history of high prices for coins in similar conditions.

Therefore, a reasonable maximum purchase price could be 200 euros.

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

1. Starting price: 100 euros.
2. Current condition: 90 (EBC), indicating good condition.

4. Average hammer price: 120 euros, which is the average price it has sold for in the past.
5. Auction expectations: It will be auctioned again in the coming days, which may influence demand.

Since the current condition is better than that of the previous auction (90 vs. 75), and considering that the average hammer price is 120 euros, we could estimate that the maximum purchase price could be in a range above the previous hammer price.

Taking all these factors into account, an estimated maximum purchase price could be approximately 130-150 euros. This reflects the good condition and potential interest in the coin, as well as the price history.

- The last auction with a condition rating of 80 had a hammer price of 340 euros.

4. Market Trends: Given that the coin will be auctioned in the near future and has shown consistent interest in the past, it is reasonable to assume that the price could be on the rise.

Based on these factors, an estimated maximum purchase price could be in the range of 300 to 350 euros, considering that the condition is good and that interest in the coin appears to be solid. Therefore, a reasonable maximum purchase price could be 350 euros.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, including auction history and previous hammer prices.

1. Current Condition: The coin has a condition of 70 (VF-), indicating that it is in acceptable shape, but not in the best possible condition.

2. Price History:
- The average hammer price for this coin in the past is 203.89 euros.
- Previous hammer prices for coins with a similar condition (70) have varied, but some relevant prices can be observed:
- 170 euros (2020-12-16)

- 140 euros (2020-10-20)
- 180 euros (2018-05-30)
- 180 euros (2018-10-15)

3. Price Trends:
- Hammer prices for coins with a condition of 70 have been in a range of approximately 140 to 190 euros in recent auctions.
- In auctions where the condition was better (80 or 85), hammer prices have been significantly higher, reaching up to 420 euros.

4. Starting Price: The current starting price is 175 euros, which is reasonable given the price history.

5. Maximum Price Estimate:
- Given that the average hammer price is 203.89 euros and considering that the condition is 70, a maximum purchase price could be set slightly above the average hammer price, but not so high as to risk paying more than what has been paid in the past for coins in similar conditions.

Based on this analysis, an estimated maximum purchase price for this coin could be 220 euros. This allows for some competition in the auction, while also remaining within a reasonable range based on the price history.
