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 75 (MBC), indicating that it is in fairly good shape, but not the best possible condition.

2. Auction History:
- The average hammer price in previous auctions is 214.09 euros.
- The last auction with a similar condition (75) had a hammer price of 300 euros.
- Overall, hammer prices have varied, but there are examples of sales exceeding 300 euros.

3. Starting Price: The starting price is 300 euros, indicating that the seller has high expectations for this auction.

4. Price Trends: Looking at previous hammer prices, it seems there is consistent interest in this coin, and prices have shown a trend of increasing in recent auctions.

Based on these factors, an estimated maximum purchase price could be around 350-400 euros. This is because, although the starting price is 300 euros, the auction history and current condition suggest that there may be competition in the auction, which could lead to a higher hammer price.

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

1. Coin Condition: The coin to be auctioned has a condition rating of 80 (MBC+). This is an important factor, as coins in better condition tend to fetch higher prices.

2. Previous Auction Prices:
- The coin has been auctioned several times with starting prices ranging from 600 to 900 euros.
- Previous hammer prices (when sold) have reached up to 1600 euros in the most recent case (2024) for a coin with a condition rating of 95, indicating that the market may be willing to pay high prices for quality coins.

3. Average Hammer Price: The average hammer price for previous auctions is 1030 euros, suggesting that, in general, coins of this reference tend to sell above their starting price.

4. Sales Trends: Of the 8 times it has been auctioned, it has sold on 4 occasions, indicating interest in the coin, but also that there is a 50% non-sale rate in the past, which may influence the perception of value.

5. Estimated Price: The estimated starting price for this auction is 600 euros, which is relatively low compared to previous hammer prices.

Based on these factors, an estimated maximum purchase price could be in the range of 1000 to 1200 euros, considering that the condition is good (80) and that there seems to be interest in the coin. However, since the highest hammer price in the past has been 1600 euros, it is possible that a buyer may be willing to pay a bit more if competition is high at the auction.

Therefore, a reasonable maximum purchase price could be 1200 euros.

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

1. Current Condition: The coin has a condition of 75 (MBC), indicating that it is in fairly good shape, but not the best possible condition.

2. Auction History:
- In the past, the coin has been auctioned 4 times, of which it has sold 3 times.
- Previous hammer prices have been 1100, 1400, and 900 euros, with an average hammer price of approximately 1133.33 euros.

3. Current Starting Price: The starting price is 900 euros, which is slightly higher than the average starting price of 825 euros.

4. Price Trends:
- In the most recent auction (2024), the coin sold for 900 euros with a condition of 85, suggesting that the market is willing to pay around this price for coins in similar conditions.
- In previous auctions, hammer prices have been higher, especially when the condition was better (85 or above).

5. Maximum Price Estimate: Given that the current condition is 75, and considering that in previous auctions with similar conditions, hammer prices have reached up to 1100 euros, a reasonable maximum purchase price could be in the range of 1000 to 1100 euros. This is based on the fact that buyers may be willing to pay a little more than the most recent lower hammer price (900 euros) if demand is high.

Therefore, an estimated maximum purchase price for this coin could be approximately 1100 euros.

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

1. Current Condition: The coin has a condition of 85 (ebc-), which indicates that it is in quite good shape. This is relevant because coins in better condition tend to fetch higher prices at auctions.

2. Previous Auction Prices: By observing the auction prices of coins with similar conditions (around 80-90), we can see that:
- In several auctions, coins with a condition of 85 have reached hammer prices ranging from 400 to 1300 euros.
- For example, in a 2020 auction, a coin with a condition of 85 sold for 1400 euros, and in another auction in 2022, a coin with a condition of 85 sold for 1550 euros.

3. Starting Price and Average Hammer Price: The starting price of the coin is 1500 euros, and the average hammer price for similar coins is 633.41 euros. However, since the starting price is quite high, bidders are likely to be willing to pay more if the coin is attractive.

4. Auction Trends: The coin has been auctioned 37 times in the past, with a high sales percentage (33 out of 37). This suggests that there is consistent interest in this coin, which may increase its value in the current auction.

5. Maximum Price Estimation: Based on the condition, previous hammer prices, and interest in the coin, a reasonable maximum purchase price could be in the range of 1200 to 1600 euros. This aligns with previous hammer prices for coins of similar condition and the current starting price.

Therefore, an estimated maximum purchase price for this coin could be 1600 euros.

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 of 85 (ebc-), indicating that it is in quite good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Previous Prices: By looking at previous auction prices for coins with a similar condition (85), we find that at the auction on 2022-12-14, a coin with the same condition was sold for a hammer price of 90 euros. This suggests that the market has valued coins in this state at a high range.

3. Starting Price and Average Hammer Price: The current starting price is 40 euros, and the average hammer price in the past has been 37.11 euros. However, given that the condition is good and there is interest in the coin (sold 30 times in the past), it is reasonable to expect that the hammer price will be above the average.

4. Auction Trends: The coin has been auctioned 30 times and has had a 100% sell-through rate, indicating strong demand. This may influence an increase in the hammer price.

5. Estimation Based on Previous Prices: Since the highest hammer price for a coin with a similar condition was 90 euros, and considering that the starting price is 40 euros, an estimated maximum purchase price could be in the range of 80 to 100 euros, depending on the competition in the auction.

Conclusion: Based on all these factors, an estimated maximum purchase price for the coin could be approximately 90 euros. This reflects both the condition of the coin and the price trends in previous auctions.

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

1. Condition: The coin has a condition rating of 80 (MS+), indicating that it is in relatively good shape. This is important because coins in better condition tend to fetch higher prices.

2. Auction History:
- It has been auctioned 5 times in the past, of which it sold 3 times.
- The average hammer price in previous auctions is 786.67 euros, suggesting that there is significant interest in this coin.
- In past auctions, hammer prices have varied considerably, with a hammer price of 1800 euros for coins with a condition rating of 95.

3. Current Starting Price: The starting price is 60 euros, which is quite low compared to the historical average hammer price.

4. Comparison with Previous Prices: The last auction with a condition rating of 80 had a hammer price that is not specified, but there is a hammer price of 60 euros for a coin with a condition rating of 10, indicating that the price could be significantly higher for a condition rating of 80.

Given all this, an estimated maximum purchase price could be in a range that considers historical interest and the current condition.

Estimation: We could estimate a maximum purchase price around 500-600 euros, considering that the average hammer price is 786.67 euros and that the condition of this coin is better than some of those that have sold in the past. However, since the starting price is 60 euros, it is likely that competition in the auction could drive the price higher, but it may not necessarily reach the historical average due to the difference in condition.

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

1. Starting Price: 60 euros.
2. Condition: The coin has a condition rating of 30 (BC+), indicating that it is not in the best condition. This may affect its value compared to coins in better condition.
3. Auction History:
- In 2017, the coin was auctioned with a starting price of 50 euros and sold for 220 euros, indicating strong interest and a final price significantly higher than the starting price.
- In 2016, the starting price was 25 euros and it sold for 40 euros, showing more moderate interest.

4. Average Hammer Price: 130 euros, which is a good indicator of the market value of the coin.

Given that the coin has a starting price of 60 euros and considering the auction history, the average hammer price, and the condition, an estimated maximum purchase price could be in a range between the average hammer price and the highest observed hammer price.

Taking all this into account, an estimated maximum purchase price could be around 150 euros. This reflects moderate interest, considering the condition of the coin and the auction history.
