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.
2. Coin condition: 70 (MBC-), indicating good condition, but not the best.

- 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, let's consider the following factors:

1. Starting Price: 60 euros. This is the initial price set for the auction.
2. Auction History: The coin has been auctioned once before, with a starting price of 30 euros and a hammer price of 180 euros. This indicates that there is significant interest in this coin, despite its condition.
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.

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.

- In 2020, a coin with a condition of 85 was sold for 190 euros.
- In 2018, another coin with the same condition sold for 160 euros.
- In 2013, a coin with a condition of 85 was auctioned for 160 euros.

3. Starting Price and Average Hammer Price: The current starting price is 175 euros, and the average hammer price for this coin in the past has been 131.62 euros. However, given that the condition is good, it is reasonable to expect that the hammer price will be above this average.

4. Recent Trends: In the most recent auctions, hammer prices have shown an increase, especially for coins in good condition. This suggests that interest in well-preserved coins is on the rise.

Based on these factors, an estimated maximum purchase price for this coin could be between 200 and 250 euros, considering that the condition is good and there is growing interest in quality coins. However, given the starting price of 175 euros, it is likely that the hammer price will not significantly exceed this range unless there is strong competition in the auction.
