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: 3000 euros.
2. Auction price history:
- The coin has had auction prices that vary significantly, from 47 euros to 3000 euros.
- The highest auction prices have been for coins in conditions of 90 and 95, which are quite good.
- The highest recorded auction price is 3000 euros, which corresponds to a starting price of 350 euros in a previous auction.

3. Condition: There is no information about the condition of this particular coin, making the estimation more uncertain. However, we can observe that coins with conditions ranging from 80 to 95 have had auction prices between 270 and 3000 euros.

4. Price trends:
- The average auction price in previous auctions is 721.38 euros, indicating that, in general, coins of this reference tend to sell for a considerably lower price than the current starting price of 3000 euros.
- The coin has been auctioned 23 times, of which 22 have sold, suggesting good demand.

5. Estimation: Given that the starting price is 3000 euros and considering the auction price history, a maximum estimated purchase price could be set at a more realistic range. Based on the average auction price and the highest prices reached in the past, a reasonable maximum purchase price could be approximately 1000 to 1500 euros, depending on the final condition of the coin.

Therefore, an estimated maximum purchase price could be 1500 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 starting price.

1. Current starting price: 1000 euros.
2. Average auction price in the past: 871.41 euros.
3. Previous auction prices:
- Auction prices have varied considerably, with some reaching up to 2600 euros in very good condition (condition value 110).
- Most auction prices are in a range of 400 to 1000 euros, with some exceptional cases.

4. Condition of the coin: There is no information about the condition of this coin, which makes the estimation more uncertain. However, based on the auction prices of similar coins, we can make an assumption.

5. Auction price analysis:
- Coins with a condition of 80 to 95 have had auction prices ranging from 600 to 1000 euros.
- Coins with a condition of 100 and 110 have reached significantly higher auction prices, but we do not have information about the condition of this coin.

Given that the starting price is 1000 euros and considering that the average auction price is 871.41 euros, an estimated maximum purchase price could be set in a range that reflects both the starting price and the potential auction price based on the condition.

Estimated maximum purchase price:
- A reasonable maximum price could be 1200 euros. This is based on the starting price and the potential that, if the coin has an acceptable condition, it could reach an auction price higher than the average.

Therefore, a maximum purchase price of 1200 euros seems to be a prudent estimate, taking into account historical data and the lack of information about the 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 rating of 85 (ebc-), indicating that it is in fairly good shape, but not the best possible condition. This may influence the price, as coins in better condition tend to fetch higher prices.

2. Starting Price and Average Hammer Price: The starting price is 1500 euros, and the average hammer price in previous auctions is 1506.88 euros. This suggests that the hammer price is usually close to the starting price.

3. Auction History: In the past, the coin has had several hammer prices. For example, in 2018 it was sold for 1100 euros with a condition rating of 95, and in 2021 it was sold for 1300 euros with a condition rating of 80. This indicates that the price can vary significantly depending on the condition and demand at the time of the auction.

4. Price Trends: Looking at previous hammer prices, the highest recorded price was 1755 euros in 2024, suggesting that there is potential for the price of this coin to increase based on demand.

Given all this, an estimated maximum purchase price could be around 1600-1700 euros. This range takes into account the current condition, price history, and the trend of increasing hammer prices. However, it is important to remember that the final price will depend on the competition in the auction and the specific demand at that time.

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

1. Starting Price: 3500 euros. This is the initial price of the auction.
2. Condition: The coin has a condition rating of 85 (MBC+/EBC-), indicating that it is in quite good shape, which may increase its value.
3. Auction History: The coin has been auctioned 2 times in the past and has sold on both occasions. This suggests that there is demand for this coin.
4. Previous Prices: In the 2013 auction, the starting price was 4800 euros and the final price was 6500 euros. This indicates that the value of the coin has been significantly higher in the past.

Given that the average final price in the past has been 5550 euros and considering the current condition, an estimated maximum purchase price could be in a range between the average final price and the highest previous final price.

Taking all these factors into account, an estimated maximum purchase price could be approximately 6000 euros. This reflects a value that considers the good condition and price history, but it is also prudent not to exceed the previous final price.

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

1. Current starting price: 3500 euros.
2. Auction history: The coin has been auctioned 16 times, of which it has sold 14 times. This indicates good demand.
3. Previous prices: Previous hammer prices varied significantly, with a maximum price of 3815.45 euros in 2014 and a minimum price of 110 euros in 2023. However, the highest hammer prices have been for coins in grade 90.
4. Condition: There is no information on the current condition of the coin, which can significantly affect its value. However, most previous auctions with grade 90 coins have reached high prices.
5. Average hammer price: The average hammer price is 1297.19 euros, suggesting that the current starting price of 3500 euros is quite high compared to the historical average.

Given that the starting price is 3500 euros and considering the auction price history, an estimated maximum purchase price could be in the range of 2500 to 3000 euros, depending on the condition of the coin and demand at the auction. This is based on the fact that the starting price is significantly higher than previous hammer prices, and without information on the condition, it is prudent not to exceed the current starting price.

Therefore, an estimated maximum purchase price could be 3000 euros.

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: 2000 euros.
2. Condition of the coin: 85 (MBC+/EBC-), which indicates good preservation.
3. Auction history: The coin has been auctioned 3 times in the past, and it has sold every time. This indicates a consistent interest in the coin.
4. Previous hammer prices: In past auctions, the hammer prices were 6500 euros and 7000 euros, both with similar preservation (85).
5. Average hammer price: 6100 euros, which is a good indicator of market value.

Given that the current starting price is significantly lower than the previous hammer prices, and considering that the condition is good, it can be estimated 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 6000 and 7000 euros, aligning with previous hammer prices. However, since the starting price is 2000 euros, there is likely to be competition in the auction, which could drive the final price up.

Therefore, a reasonable estimated maximum purchase price could be 7000 euros.

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

1. Current data of the coin:
- Starting price: €5000
- Condition: 95 (EF+)

2. Historical data:
- Average hammer price: €4704.59
- Previous prices from auctions of coins with similar conditions (around 90-95):

3. Analysis of previous prices:
- In the past, coins with conditions of 90 have reached hammer prices of up to €17,000 or more, depending on demand and rarity.
- The last reference auction shows a starting price of €6000 and an estimated price of €12000, indicating that the market is willing to pay more for high-condition coins.

4. Maximum price estimation:
- Given that the condition of the coin is high (95), and considering the starting price and the average hammer price, a reasonable maximum purchase price could be in the range of €10,000 to €12,000.
- However, given the historical hammer price records for similar conditions, a maximum purchase price could be up to €15,000 if demand is high.

Conclusion: An estimated maximum purchase price for this coin could be between €12,000 and €15,000, depending on the competition in the auction and the interest from collectors.

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

1. Starting Price: 2000 euros.

Given that the coin to be auctioned has a condition of 90, which is quite high, and considering the auction price history, we can make an estimation.

- The last auction with a condition of 90 had a hammer price of 15500 euros, suggesting that the value could be considerably high.
- However, the current starting price is 3500 euros, which may be a good starting point.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 6000 to 8000 euros, considering that the hammer price can be significantly higher than the starting price, especially for coins in good condition.

Therefore, a reasonable maximum purchase price could be 7000 euros.

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

1. Current starting price: 3000 euros.

- In 2019, it was auctioned with a starting price of 900 euros and sold for 1050 euros, with a grade of 50.

3. Average hammer price: 4100 euros, indicating that, in general, coins of this reference tend to sell for a price higher than the starting price.

4. Condition: There is no information about the condition of the current coin, which may influence its value. However, the hammer price of the coin with a grade of 85 (5000 euros) suggests that good condition can significantly increase the price.

Given that the starting price is 3000 euros and considering the auction price history, an estimated maximum purchase price could be between the average hammer price (4100 euros) and the highest hammer price (5000 euros) from the previous auction.

Therefore, an estimated maximum purchase price could be approximately 4500 euros. This reflects a balance between the current starting price and the potential hammer price based on previous auctions.

1. Current starting price: 2000 euros.
2. Average hammer price in the past: 541.79 euros.
3. Previous hammer prices: There are several hammer prices that varied significantly, with some reaching very high figures (for example, 2400 euros in 2019).
4. Condition: No information is provided about the condition of this coin, which may affect its value. However, it is noted that in previous auctions, coins with conditions ranging from 70 to 95 have had hammer prices that varied significantly.

Given that the starting price is 2000 euros, which is considerably higher than the previous average hammer price, it is reasonable to assume that the hammer price could be influenced by current demand and the quality of the coin.

### Estimation of the maximum purchase price:
- Based on the highest hammer price: 2400 euros (from 2019).
- Based on the starting price: If we consider that the starting price is an indicator of the seller's expectation, we could estimate that the hammer price could be in a range of 2000 to 2400 euros, depending on demand.

### Conclusion:
An estimated maximum purchase price could be between 2000 and 2400 euros, with 2400 euros being an upper limit based on the highest hammer price recorded in the past. However, since the starting price is 2000 euros, it is likely that the hammer price will not significantly exceed this value unless there is exceptional interest in the coin. Therefore, a reasonable maximum purchase price could be 2400 euros.
