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. Current Listing Price and Previous Prices: The current listing price is 1800 euros. The average hammer price in previous auctions is 1892.08 euros, suggesting that similar coins have reached prices close to this value.

3. Historical Trends: By observing previous hammer prices for coins with similar conditions (85 and 90), we can see that they have reached hammer prices that vary but are generally above the current listing price. For example, in the auction on 2022-03-17, a coin with a condition of 90 was hammered at 2800 euros.

4. Demand and Supply: The coin has been auctioned 28 times in the past, with a sell-through rate of 96.4% (27 out of 28). This indicates good demand, which could push the price up.

5. Comparison with Recent Hammer Prices: In recent auctions, hammer prices for coins of similar condition have ranged from 1800 to 2800 euros, suggesting that the hammer price could be in a similar range.

Taking all these factors into account, an estimated maximum purchase price for this coin could be between 2200 and 2500 euros. This is based on the condition, the price trend in previous auctions, and the observed demand.

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

1. Current Condition: The coin has a condition rating of 85 (ebc-), indicating that it is in quite good shape. This is a positive factor that can increase its value.

2. Auction History:
- The average hammer price for similar coins in the past has been 1182 euros.
- In previous auctions, the hammer price has varied, but it has reached up to 2400 euros in a recent auction with a similar condition (85).
- Most coins with a condition of 85 have had hammer prices ranging between 950 and 1400 euros.

3. Starting Price: The current starting price is 1800 euros, which is higher than the average starting price of 983.33 euros. This may indicate that the seller has high expectations, but it could also be an indicator of current demand.

4. Sales Trends: The coin has been sold in 18 of the last 20 auctions, suggesting there is consistent interest in this coin.

5. Comparison with Previous Prices: In previous auctions, coins with a condition of 85 have reached hammer prices of up to 1400 euros, but there is also a recent case where it sold for 2400 euros.

Based on these factors, an estimated maximum purchase price could be between 1800 and 2400 euros, considering that the starting price is 1800 euros and there are precedents for higher sales. However, since the average hammer price has been 1182 euros, a more conservative price could be around 2000 euros, reflecting a balance between the starting price and the sales history.

Therefore, a reasonable estimated maximum purchase price could be 2000 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 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 will consider several factors:

1. Current Condition: The coin has a condition of 70 (MBC-), which indicates that it is in relatively good shape, but not among the best qualities. This may influence the price, as coins in better condition tend to fetch higher prices.

2. Previous Prices:
- In the 2020 auction, the coin sold for 150 euros with a condition of 30.
- In 2021, it sold for 120 euros, also with a condition of 30.
- In 2016, although it did not sell, the starting price was 350 euros, indicating that there were high expectations at that time.

3. Starting Price and Average Price: The current starting price is 110 euros, and the average hammer price in previous auctions is 135 euros. This suggests that the market expects the coin could sell for a price close to this average.

4. Demand and Supply: The coin has been auctioned 3 times in the past, of which it has sold 2 times. This indicates moderate interest in the coin, but also that there is a possibility it may not sell this time, given that there was one auction where it did not sell.

5. Market Trends: Since the average starting price is 166.67 euros, this suggests that the market is willing to pay more than the current starting price.

Taking all these factors into account, an estimated maximum purchase price could be around 150-180 euros. This is based on the previous hammer price and the current condition of the coin. However, since the starting price is 110 euros, it is possible that buyers may be willing to bid more, especially if there is interest in the coin.

Therefore, a reasonable maximum purchase price could be 180 euros.

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

1. Starting price: 60 euros.
2. Current condition: 50 (fine), indicating average quality.
3. Auction history:
- In 2020, it sold for 95 euros with a condition of 30.
- In 2020, it sold for 65 euros with a condition of 70.
- In 2016, it sold for 75 euros (no condition information).
- In 2022, it sold for 80 euros with a condition of 30.

4. Average hammer price: 78.75 euros, indicating that, in general, coins of this reference tend to sell above the starting price.

5. Price trends: We observe that coins in better condition have reached higher prices. The condition of 70 reached a hammer price of 65 euros, while the condition of 30 had hammer prices of 95 and 80 euros.

Given that the condition of the coin at auction is 50, which is intermediate, and considering the average hammer price of 78.75 euros, we can estimate that the maximum purchase price could be in a range above the starting price, but not as high as the hammer prices of the higher conditions.

Estimated maximum purchase price: It may be reasonable to set a maximum purchase price around 85-90 euros, as this aligns with the price history and current condition. This allows for a margin for competition in the auction, considering that the starting price is 60 euros.

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

1. Starting Price: 90 euros.
2. Condition: The coin has a condition rating of 30 (BC+), indicating that it is not in very good shape. This may affect its value compared to coins in better condition.
3. Auction History:
- In 2016, the coin was auctioned with a starting price of 25 euros and sold for 35 euros.
- In 2014, the starting price was 60 euros, with a final bid of 110 euros.
- In 2021, although there was no starting price, it was estimated at 100 euros and sold for 240 euros, but the condition was rated at 70, which is significantly better than the current one.

4. Average Final Price: 128.33 euros, indicating that, in general, coins of this reference tend to reach higher prices at auctions.

5. Auction Trends: The coin has sold on all previous occasions, suggesting a consistent interest in this reference.

Given that the current condition is 30, which is quite low, and considering the starting price of 90 euros, an estimated maximum purchase price could be in a range that reflects both the interest in the coin and its condition.

Taking all these factors into account, an estimated maximum purchase price could be around 100-120 euros. This allows for some competition in the auction while also reflecting the condition of the coin.

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

1. Starting Price: 60 euros. This is the initial price of the auction.
2. Condition: The coin has a condition of 30 (BC+), indicating that it is not in very good shape. This may affect its value compared to coins in better condition.
3. Auction History: The coin has been auctioned once in the past, with a starting price of 80 euros and a hammer price of 120 euros. This suggests that, despite its condition, there is interest in the coin that could lead to a higher hammer price.
4. Average Starting and Hammer Prices: The average starting price is 70 euros and the average hammer price is 120 euros. This indicates that, in general, coins of this reference tend to sell for higher prices.

Given that the coin has a condition of 30, it is likely that its hammer price will not reach the historical maximum of 120 euros, but it could be in a lower range. Considering the starting price of 60 euros and the demonstrated interest in the previous auction, an estimated maximum purchase price could be between 80 and 100 euros.

Therefore, a reasonable estimated maximum purchase price for this coin could be 90 euros. This takes into account its condition and the historical interest in the coin.

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.

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

1. Starting Price: 75 euros. This is the initial price of the auction.
2. Auction History: The coin has been auctioned once in the past and sold for 80 euros, which is the average hammer price.
3. Condition: The coin has a condition rating of 30 (BC+), indicating that it is not in the best condition, but it is also not among the worst.
4. Average Starting and Hammer Prices: The average starting price of 62.5 euros and the average hammer price of 80 euros suggest that interest in this coin may be moderate.

Given that the coin has a starting price of 75 euros and considering that it was sold for 80 euros in the past, an estimated maximum purchase price could be slightly above the previous hammer price, but it must also take into account the current condition.

Taking all these factors into account, an estimated maximum purchase price could be approximately 85 euros. This allows for a small margin above the previous hammer price, considering the possibility that interest in the coin remains steady or increases slightly in this auction.

Given that the coin has a grade of 50 (fine) and there are no historical data from previous auctions, it is difficult to establish a maximum estimated purchase price based on prior experience. However, we can consider some factors:

1. Starting Price: The starting price is 60 euros, which indicates the minimum value expected to be obtained at the auction.
2. Condition: A grade of 50 (fine) suggests that the coin is in an acceptable state, but it is not of high quality. This may limit collectors' interest and, therefore, the price.
3. No Previous Sales: The lack of previous sales may indicate that there is no established market for this particular coin, which could make bidders more cautious.

Given these factors, a maximum estimated purchase price could be slightly higher than the starting price, but not by much, as the condition is not high and there is no sales history to support a higher price.

Therefore, a maximum estimated purchase price could be in the range of 70 to 80 euros. This would allow bidders to have a margin to compete, but it also reflects the uncertainty given the lack of historical data.

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

1. Starting price: 90 euros.
2. Coin condition: 70 (MBC-), indicating an acceptable condition.
3. Auction history:
- In 2020, the coin was auctioned with a starting price of 30 euros and sold for 130 euros.
- In 2016, the starting price was 100 euros, with a final bid of 100 euros.
- In 2018, the starting price was 70 euros and sold for 130 euros.

4. Average final bid price: 120 euros, indicating that, in general, coins of this reference tend to sell for above their starting price.

Given that the coin has a condition of 70 and considering the history of final bid prices, we can make an estimation. The trend shows that, despite a starting price of 90 euros, the final bid price is usually significantly higher.

Based on the average final bid price of 120 euros and the fact that the coin has performed well in previous auctions, an estimated maximum purchase price could be around 120-130 euros, considering that the starting price is 90 euros and that the condition is acceptable.

Therefore, an estimated maximum purchase price could be 130 euros.

3. Condition of the coin: 70 (MBC-), which indicates good condition, although not the best.
4. Auction history: It has been auctioned once in the past and sold on that occasion, suggesting there is interest in the coin.

Given that the average hammer price in the past was 65 euros and considering that the condition of this coin is good (70), it is reasonable to think that the hammer price could be in a similar range or slightly higher, especially if there is interest in the current auction.

Taking all these factors into account, an estimated maximum purchase price could be between 70 and 80 euros. This is based on the fact that the condition is good and that interest in the coin could lead to a hammer price higher than the previous average.

Therefore, an estimated maximum purchase price could be 75 euros.

4. Average final price: 88.33 euros, suggesting that, in general, coins of this reference tend to sell for a price higher than the starting price.

Given that the condition of the current coin is 30, which is lower than that of the 2022 auction, it is likely that the final price will not reach the higher levels observed in that auction. However, considering the average final price and the auction history, an estimated maximum purchase price could be in a range between the starting price and the average final price.

Taking all these factors into account, an estimated maximum purchase price could be approximately 80-90 euros. This is based on the fact that, although the condition is not the best, the interest in the coin and the bidding history suggest that it could reach a reasonable price at auction.

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

1. Current starting price: 75 euros.

3. Condition: The coin has a condition rating of 30 (BC+), suggesting that it is not in the best condition, but it may still hold considerable value.
4. Average Hammer Price: The average hammer price for this coin in the past was 180 euros, indicating that, despite its condition, there is a market willing to pay a high price.

Given that the average hammer price is significantly higher than the current starting price, and considering that the coin has a history of successful sales, we could estimate that the maximum purchase price could be in a higher range.

Taking all these factors into account, an estimated maximum purchase price could be between 150 and 200 euros, given that the previous hammer price was 180 euros and the interest in the coin appears to be high. However, since the condition is not excellent, it is wise not to exceed 200 euros.

Therefore, a reasonable maximum purchase price could be 180 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 rating of 80 (MBC+). This is an important factor, as coins in better condition tend to fetch higher prices.

2. Starting Price and Average Prices: The current starting price is 90 euros, and the average starting price in previous auctions is 140.36 euros, with an average hammer price of 190.33 euros. This suggests that the coin could sell for a significantly higher price than its starting price.

3. Auction History:
- In the past, the coin has had hammer prices that varied considerably, ranging from 50 euros to 550 euros, depending on the condition.
- The last auction of a coin with a similar condition (85) had a hammer price of 200 euros.

1. Coin Condition: The coin has a condition rating of 95 (S/C-), indicating that it is in very good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Previous Auction Prices: By looking at previous hammer prices for coins with a similar condition (95), we can see that they have reached hammer prices of up to 180 euros in the most recent auction (2024-01-18) and 150 euros in another auction (2024-05-30).

3. Average Hammer Price: The average hammer price for this coin is 128.67 euros, which is also a good indicator of the expected value.

4. Starting Price: The current starting price is 110 euros, suggesting that the seller has expectations of a higher hammer price.

5. Sales Trends: The coin has been auctioned 30 times, of which 27 have been sold, indicating good demand and a history of successful sales.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 150 to 180 euros, as this is the range of hammer prices achieved in previous auctions for coins of similar condition.

Therefore, a reasonable maximum purchase price could be 170 euros. This allows for some competition in the auction and aligns with previous hammer prices.

4. Price Trends:
- Since the coin has been auctioned 23 times and has had a sell-through rate of 95.65% (22 out of 23), this suggests there is consistent interest in this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 70 to 90 euros, considering that the condition is good and there are precedents of higher hammer prices in the past. However, given the auction history and interest in the coin, a maximum purchase price of 80 euros could be a reasonable estimate.

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

1. Coin Condition: The coin to be auctioned has a condition rating of 95 (EBC+), indicating that it is in very good condition. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History: By observing the hammer prices of coins with similar conditions (95 and 90), we can see that the hammer prices have varied, but generally, coins in EBC+ condition have reached hammer prices ranging from 60 to 140 euros in previous auctions.
