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: 2500 euros.
2. Average past starting price: 2650 euros.
3. Average past auction price: 3950 euros.
4. Auction history: The coin has been auctioned 3 times and has sold on all occasions, indicating consistent interest.
5. Condition values: Although there is no specific information about the condition of this coin, previous auction prices (2200 and 2900 euros) suggest that condition may be an important factor.

Given that the average auction price is significantly higher than the current starting price, and considering that the coin has a history of successful sales, it can be inferred that there is potential for price increase.

However, the lack of information about the condition may make buyers more cautious. Therefore, an estimated maximum purchase price could be positioned between the average auction price and the average starting price, adjusted for the uncertainty of the condition.

Estimated maximum purchase price: 3500 euros.

This price reflects a balance between historical interest in the coin and the lack of information about its current state.

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

1. Current Condition: The coin has a condition rating of 85 (ebc-), indicating that it is in quite good shape. This suggests that its value should be in the upper range of previous auctions.

2. Previous Auction Prices: Previous auction prices for coins with similar conditions (around 75 to 85) have varied, but the highest recorded price was 9500 euros in 2017. However, most auction prices for coins in the 75 condition range have been around 2400 to 4200 euros.

3. Average Auction Price: The average auction price for this coin is 4838.78 euros, providing a good reference point.

5. Auction Trends: The coin has sold in 9 out of the last 10 auctions, indicating consistent demand.

Based on these factors, an estimated maximum purchase price could be in the range of 4000 to 5000 euros, considering that the condition is good and the average auction price is 4838.78 euros.

Therefore, a reasonable maximum purchase price could be 4500 euros. This allows for a margin for competition in the auction and reflects the coin's condition value.

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

1. Current starting price: 1000 euros.
2. Average hammer price in the past: 1448.25 euros.
3. Auction history:
- The coin has been auctioned 9 times and has sold on all occasions.
- Previous hammer prices varied, but there are some relevant data:
- In 2018, a coin with a condition of 70 was hammered at 700 euros.
- In 2018, another coin with a condition of 80 was also hammered at 700 euros.
- In 2015, a coin with a starting price of 1800 euros was hammered at 2000 euros (no condition information available).
- In 2022, a coin with a condition of 30 was hammered at 260 euros.

4. Condition: There is no information about the condition of the current coin, which complicates the estimation a bit. However, we can observe that coins with conditions of 70 and 80 sold for 700 euros, and those with a condition of 30 sold for 260 euros.

5. Estimation: Given that the average hammer price is 1448.25 euros and considering that the starting price is 1000 euros, a reasonable maximum purchase price could be in a range above the starting price, but not as high as the average hammer price, given the lack of information about the condition.

Taking all these factors into account, an estimated maximum purchase price could be around 1200 to 1300 euros. This is based on the fact that the starting price is 1000 euros and the average hammer price is significantly higher, but also considering the lack of information about the current condition.

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 (MBC+/EBC-), which indicates that it is in quite good shape. This generally translates to a higher price compared to coins of lower condition.

2. Previous Auction Prices:
- In previous auctions, we have seen hammer prices that vary significantly. For example, in the March 2023 auction, a coin with a condition of 95 sold for 34,000 euros, indicating a strong market for high-quality coins.
- In other auctions, hammer prices have ranged between 2,500 and 8,000 euros for similar conditions (85).

3. Average Hammer Price: The average hammer price for this coin is 8,907.14 euros, suggesting that, in general, buyers are willing to pay a considerably higher price than the starting price.

4. Starting Price and Average Starting Price: The starting price is 2,000 euros, and the average starting price is 2,900 euros. This indicates that the current starting price is relatively low compared to the average hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 8,000 to 10,000 euros, considering that the condition is good and that interest in quality coins seems to be high. However, since the highest hammer price in the past was 34,000 euros, it is possible that some buyers may be willing to pay more, but this will depend on the competition in the auction and the interest of collectors at that time.

Therefore, a reasonable maximum purchase price could be approximately 9,000 to 10,000 euros.

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

1. Current price and previous prices: The current starting price is 3500 euros, which is slightly higher than the average starting price of 3457.14 euros. However, the average hammer price in previous auctions is 5491.67 euros, indicating that, in general, coins of this reference tend to sell for a price higher than the starting price.

4. Price trends: Looking at previous hammer prices, the lowest was 3200 euros and the highest was 8750 euros. This indicates a wide range, but also suggests that, in general, prices tend to be higher than the starting price.

However, it is important to take into account the lack of information about the current condition, which could affect the final value.

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