To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the starting and hammer prices from previous auctions, as well as the coin's condition.

1. Current starting price: 2500 euros.
2. Average starting price in the past: 1415 euros.
3. Average hammer price in the past: 1396 euros.
4. Auction history: The coin has been auctioned 13 times, of which it has sold 10 times. This indicates good demand.
5. Condition: There is no information on the current condition, but in previous auctions, conditions have varied between 10 and 100.

### Analysis of previous prices:
- The auction with the highest hammer price was 4250 euros, although there is no information on the condition.
- The most recent auction with a known hammer price was 440 euros with a condition of 95.
- Hammer prices have varied considerably, suggesting that condition plays an important role in the final price.

### Estimation:
Given that the current starting price is 2500 euros and considering that the average hammer price in the past is 1396 euros, it seems that the starting price is quite high compared to the historical average. However, the good demand (10 out of 13 auctions sold) and the fact that there have been auctions with hammer prices above 4000 euros suggest that there could be significant interest.

If we consider that the starting price is an indicator of the seller's expectation and that the highest hammer price in the past was 4250 euros, an estimated maximum purchase price could be positioned between the starting price and the highest hammer price.

### Estimated maximum purchase price:
Estimation: 4000 euros.

This price reflects a balance between the current starting price and the history of hammer prices, taking into account demand and variability in condition.

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

2. Auction History:
- The average hammer price for this coin in the past is 829.44 euros, suggesting that buyers are willing to pay significantly more than the starting price on many occasions.
- The last auction with a similar condition (80) had a hammer price of 395 euros in 2014, and 700 euros in 2022, indicating that interest and value for the coin have fluctuated, but tend to be higher in better conditions.

3. Starting Price and Average Hammer Price:
- The current starting price is 500 euros, which is reasonable given the price history. However, the average hammer price suggests that it could reach a higher price.

4. Market Trends: Given that the coin has been auctioned 16 times and all have sold, this indicates a consistent interest in the coin, which may increase its value.

Based on these factors, an estimated maximum purchase price could be in the range of 900 to 1100 euros, considering that the average hammer price has been 829.44 euros and that the current condition is quite good. This also takes into account the possibility that buyers may be willing to pay a bit more for a coin in good condition.

Therefore, an estimated maximum purchase price could be 1000 euros.

To estimate a maximum purchase price for the coin in question, we will 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 at auctions.

2. Previous Auction Prices:
- The average hammer price for this coin in previous auctions is 2943.75 euros.
- In the 2022 auction, the coin sold for 7500 euros with a condition rating of 95, indicating that coins in better condition can reach significantly higher prices.
- In the 2024 auction, the same coin was hammered at 3000 euros with a condition rating of 80, which is relevant for our estimation.

3. Starting Price and Average Starting Price:
- The current starting price is 1500 euros, which is below the average starting price of 1661.11 euros. This suggests that the starting price is reasonable and could attract more bidders.

4. Sales Trends: The coin has been auctioned 9 times, of which it has sold 8 times. This indicates a consistent interest in the coin, which may influence the hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 2500 to 3000 euros, considering that the condition is 80 and that in previous auctions it has reached hammer prices of up to 3000 euros under similar conditions.

Therefore, a reasonable maximum purchase price could be approximately 2800 euros.

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

1. Starting price: 2500 euros.
2. Auction history: The coin has been auctioned 14 times, of which it has sold 13 times. This indicates good demand.
3. Average starting price: 1707.69 euros.
4. Average hammer price: 2199.23 euros.

### Analysis of previous prices:
- In previous auctions, hammer prices have varied considerably, but there is a pattern where coins with conditions from 75 to 90 have reached hammer prices exceeding 2000 euros.
- The last auction with a known hammer price was 2200 euros, suggesting that the market is willing to pay in that range.

### Estimation:
Given that the starting price is 2500 euros and considering that the average hammer price has been 2199.23 euros, a reasonable maximum purchase price could be in the range of 2500 to 3000 euros, depending on the demand and the condition of the coin.

Estimated maximum purchase price: 2800 euros.

This price reflects a balance between the starting price and the history of hammer prices, taking into account the lack of information about the specific condition of this coin.

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

2. Starting Price and Average Hammer Price: The starting price is 2000 euros, and the average hammer price in previous auctions is 2361.76 euros. This suggests that, in general, coins of this reference tend to sell for above the starting price.

3. Auction History: In the auction history, it is observed that the coin has had hammer prices that varied, but on several occasions, it has exceeded 2000 euros, even reaching up to 4400 euros in a recent auction (2023-03-16) with a condition rating of 95.

4. Price Trends: Hammer prices have shown an upward trend in recent years, especially for coins in good condition. The last auction with a hammer price of 4400 euros suggests that there is growing interest in this coin.

Based on these factors, an estimated maximum purchase price could be set in a range between 3000 and 3500 euros, considering that the coin's condition is good and that interest in this type of coin seems to be increasing. This also allows for a margin for competition in the auction.

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

1. Starting price: 2500 euros.
2. Average hammer price: 3400 euros. This is an important figure, as it indicates the average price at which it has sold in the past.
3. Condition of the coin: 75 (VF - Very Fine). This suggests that the coin is in good condition, which can increase its value.
4. Auction history: The coin has been auctioned once and sold on that occasion, indicating that there is interest in it.

Given that the average hammer price is 3400 euros and the condition is good, we could estimate that the maximum purchase price could be in a range above the average hammer price, especially if there is interest in the coin.

Taking these factors into account, an estimated maximum purchase price could be between 3500 and 4000 euros, depending on the demand at the auction and the interest from collectors.

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 95 (EBC+), 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 auction prices for coins with a similar condition (95), we find that in recent auctions, the hammer prices have been:
- 5000 euros (2023-03-16)
- 3400 euros (2024-03-14)
- 3200 euros (2024-02-14)

3. Average Hammer Price: The average hammer price for this coin is 2276.47 euros, which is also a good indicator of the expected value.

5. Auction Trends: The coin has been auctioned 21 times, with an 85.71% sell-through rate (18 out of 21). This suggests that there is consistent interest in the coin.

Based on these factors, an estimated maximum purchase price could be between 3000 and 4000 euros, considering that the highest recent hammer price was 5000 euros and that the coin's condition is high. However, since the starting price is 1500 euros, it is likely that the final hammer price will be closer to the lower end of this range, but still, it is reasonable to expect that a buyer would be willing to pay up to 4000 euros for it.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the hammer prices and starting prices from previous auctions, as well as the average hammer and starting prices.

1. Current starting price: 2000 euros.

Final estimation: A maximum purchase price could be approximately 4000 euros. This is based on the average hammer price and the trend that coins of this reference usually sell for above their starting price.

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

1. Coin Condition: The coin has a condition rating of 95 (EBC+), 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:
- The average hammer price for similar coins has been 3,380.73 euros.
- In previous auctions, coins with a similar condition (95) have reached hammer prices of up to 4,800 euros (in the auction on November 11, 2021).

3. Starting Price: The current starting price is 1,800 euros, which is significantly lower than previous hammer prices.

4. Price Trends: Observing the hammer prices of coins with a condition of 95, it can be noted that prices tend to range from 3,000 to 4,800 euros, depending on demand and other market factors.

Based on these points, an estimated maximum purchase price could be set in a range between 4,000 and 4,500 euros, as this price reflects both the condition of the coin and previous hammer prices. However, it is important to consider that the final price may vary depending on competition in the auction and other market factors at the time of the auction.

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

1. Starting Price: 3000 euros.
2. Condition: The coin has a condition of 80 (MS+), indicating that it is in quite good shape.
3. Historical Data:
- In December 2018, a coin with a condition of 75 was auctioned with a starting price of 4000 euros and sold for 6000 euros.
- In March 2018, another coin with the same condition of 75 had a starting price of 1500 euros and sold for 3800 euros.

4. Average Hammer Price: 4533.33 euros, indicating that, in general, coins of this reference tend to sell above their starting price.

Given that the condition of the coin in question is better (80) than the previous ones (75), it is reasonable to assume that its hammer price could be higher than the previous examples.

### Estimation of the Maximum Purchase Price:
- Considering the average hammer price (4533.33 euros) and the fact that the condition is better, we could estimate that the hammer price could be in a higher range.
- A conservative approach could be to add 10-20% to the average hammer price, given the state of preservation.

Therefore, an estimated maximum purchase price could be in the range of 5000 to 5500 euros. This is based on the trend of previous prices and the better condition of the current coin.
