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

2. Historical Prices: Looking at previous auction prices for coins with a similar condition (80), we find that:
- In 2018, a coin with a condition of 80 was auctioned for 125 euros.
- In 2020, another coin with a condition of 80 was auctioned for 65 euros.

3. Average Auction Price: The average auction price for this reference is 104.08 euros, which is also a good indicator of market value.

4. Starting Price and Previous Sales: The current starting price is 35 euros, and there have been 15 previous auctions, of which 13 resulted in sales. This suggests that there is consistent interest in this coin.

5. Auction Trends: Given that the coin has been successfully auctioned in the past and considering the average auction price, it is reasonable to assume that interest in this coin will remain.

Based on these factors, an estimated maximum purchase price could be in the range of 100 to 125 euros, as this reflects both the condition of the coin and previous auction prices. Therefore, a reasonable maximum purchase price could be 120 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 Hammer Price: The starting price is 75 euros, and the average hammer price in previous auctions is 163.09 euros. This suggests that, in general, coins of this reference tend to sell for a significantly higher price than their starting price.

3. Auction History: By observing the hammer prices of previous auctions for coins with similar conditions (80 and 85), we can see that they have reached hammer prices that vary, but in many cases exceed 100 euros. For example, in recent auctions, they have sold for 190 euros and 240 euros.

4. Recent Trends: In the most recent auctions, hammer prices have shown an increase, which could indicate a rising trend in interest for this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 200 to 250 euros, considering that the coin has a condition rating of 80 and that interest in coins of this reference seems to be increasing.

Therefore, a reasonable maximum purchase price could be 250 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 70 (VF-), indicating that it is in an acceptable state, but not of the highest quality.

2. Previous Auction Prices: By observing the auction prices of coins with a similar condition (70), we can see that they have varied, but generally sold in a range of 50 to 150 euros. For example:
- In 2020, a coin with a condition of 70 was auctioned for 60 euros.
- In 2019, it was auctioned for 51 euros.
- In 2018, it was auctioned for 50 euros.

3. Average Auction Price: The average auction price for this coin is 97.68 euros, suggesting that, in general, coins of this reference tend to sell for a price above 50 euros.

4. Starting Price: The current starting price is 40 euros, which is relatively low compared to previous auction prices.

5. Trends: Since the coin has been auctioned 34 times and has had a sell-through rate of 94% (32 out of 34), this indicates a consistent demand.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 90 to 110 euros, considering that the average auction price is 97.68 euros and that the condition is acceptable. 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. Condition: The coin has a condition of 70 (MBC-), which indicates that it is in relatively good shape. This generally increases its value compared to coins with lower conditions.

2. Current listing price and previous prices: The current listing price is 75 euros, which is higher than the average listing price of 40 euros and the average hammer price of 67.33 euros. However, in the 2024 auction, the coin sold for 80 euros, suggesting that there is growing interest in this coin.

3. Auction history: The coin has been auctioned 3 times and has sold in all of them, indicating that there is demand. The fact that there have been no failed sale attempts is also a good indicator.

4. Price trends: The highest hammer price in the past was 80 euros, which sets an upper limit for the coin's value.

Taking these factors into account, an estimated maximum purchase price could be slightly above the previous highest hammer price, while also considering the current listing price.

Therefore, an estimated maximum purchase price could be approximately 85-90 euros. This reflects both the interest in the coin and its good condition, without exceeding the previous hammer price too much.

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

1. Starting Price: 70 euros.
2. Condition: The coin has a condition rating of 75 (MBC), indicating that it is in fairly good shape.
3. Auction History:
- It has been auctioned 5 times in the past, of which it has sold 4 times.
- The average hammer price in previous auctions is 108.75 euros.
- In the most recent auction (2023-12-18), the coin was hammered at 40 euros, but in a previous auction (2020-04-29), it was hammered at 250 euros, indicating variability in prices depending on demand and condition.

4. Average Starting and Hammer Price: The average starting price is 50 euros, but the average hammer price is significantly higher (108.75 euros), suggesting that buyers are willing to pay more than the starting price.

Given that the condition of the coin is good (75) and considering the hammer price history, an estimated maximum purchase price could be positioned in a range between the average hammer price and a bit more, given that the coin has a starting price of 70 euros.

Estimated Maximum Purchase Price: It could be reasonable to estimate a maximum purchase price of around 150-200 euros, taking into account the hammer price history and the condition of the coin. This would allow for competitive bidding in the auction without exceeding the market value observed in previous auctions.
