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.

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.

3. Average Hammer Price: The average hammer price for this particular coin is 38.74 euros, but given the high condition, we can expect the actual hammer price to be significantly higher.

4. Starting Prices and Previous Estimates: The current starting price is 30 euros, and the average starting price in the past has been 30.48 euros. However, the estimated price in previous auctions for coins of similar condition has been higher.

5. Recent Trends: In the most recent auctions, we have seen hammer prices reaching up to 140 euros for coins in condition 100, suggesting that there is an active market willing to pay higher prices for well-preserved coins.

Taking all these factors into account, an estimated maximum purchase price for this coin, considering its high condition and the history of hammer prices, could be around 100-120 euros. This reflects a balance between the condition, price history, and market trend.

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 90 (EF), indicating that it is in quite good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Auction History:
- The average hammer price in the past has been 43.81 euros.
- The last auction of a coin with a similar condition (95) had a hammer price of 160 euros, suggesting that coins in very good condition can reach high prices.
- Overall, hammer prices have varied, but there are examples of coins with similar conditions that have sold for significantly higher prices.

3. Starting Price and Estimates:
- The current starting price is 40 euros, which is a good starting point.
- The average starting price in the past has been 37 euros, indicating that the current starting price is reasonable.

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.

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 consider several factors based on the provided data:

1. Starting price: 60 euros.
2. Coin condition: 30 (BC+), indicating that the coin has a relatively low state of preservation.
3. Auction history:
- In 2016, the coin was auctioned with a starting price of 40 euros and sold for 70 euros.
- In 2014, the starting price was 15 euros and it sold for 35 euros.
- In 2022, the starting price was 40 euros, with a final bid of 160 euros, but the condition in this case was 70, indicating that the coin was in better shape.

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 will consider several factors:

1. Coin 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. Auction History: By looking at previous hammer prices for coins with similar conditions (around 80-90), we can see that hammer prices have varied. For example:
- In previous auctions, coins with a condition of 85 have reached hammer prices of up to 90 euros.
- The average hammer price for coins of similar condition seems to be around 80-90 euros.

3. Starting Price and Average Hammer Price: The current starting price is 60 euros, and the average hammer price in the past has been 84.29 euros. This suggests that the hammer price could be in a similar range or slightly higher.

4. Recent Trends: In the most recent auctions, hammer prices for coins of similar condition have shown a range of 70 to 110 euros, indicating a growing interest in coins in good condition.

Based on these factors, an estimated maximum purchase price for this coin could be between 90 and 110 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate.

Therefore, a reasonable maximum purchase price could be 100 euros.

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.

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.
2. Coin condition: 70 (MBC-), indicating good condition, but not the best.
3. Auction history:
- In 2016, the coin was auctioned with a starting price of 50 euros and sold for 85 euros.
- In 2022, the starting price was 45 euros, with a final bid of 170 euros, indicating strong interest in that particular auction.
4. Average final bid price: 127.5 euros, which is a good indicator of market value.
5. Average starting price: 56.67 euros, which is lower than the current starting price.

Given that the coin has a history of final bids exceeding the starting price and considering its good condition, an estimated maximum purchase price could be set in a range that reflects both market interest and the coin's condition.

Taking all these factors into account, an estimated maximum purchase price could be around 150 euros. This is based on the average final bid price and the interest shown in previous auctions, as well as the coin's condition.

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.
