To estimate a maximum purchase price for the coin in question, we can 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. Current Starting Price and Previous Prices: The current starting price is 1500 euros, and the average hammer price in previous auctions is 1151.74 euros. This suggests that the starting price is relatively high compared to the average hammer price.

3. Sales History: The coin has been auctioned 18 times, of which it has sold 14 times. This indicates good demand, which can influence the price.

4. Previous Hammer Prices: Looking at previous hammer prices, the highest recorded price was 3200 euros, although this was for a coin with unspecified condition. However, there are also lower prices around 800-1000 euros for lower conditions.

5. Price Trends: The average starting price in previous auctions is 926.85 euros, suggesting that the current starting price of 1500 euros is significantly higher than the historical average.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 1200 to 1600 euros. This is based on the good condition of the coin and the demonstrated interest in previous auctions, but also considering that the current starting price is higher than the historical average.

Therefore, a reasonable maximum purchase price could be 1600 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 of 75 (VF), indicating that it is in fairly good shape, although not the best possible condition.

2. Previous Prices:
- In the December 2019 auction, the coin was auctioned with a starting price of 2500 euros and sold for 6500 euros, with a condition of 80.
- In May 2017, the coin was auctioned with a starting price of 4500 euros and sold for 4500 euros, although the condition is not specified.

3. Average Starting and Final Prices: The average starting price is 3000 euros and the average final price is 4500 euros. This suggests that, in general, coins of this reference tend to reach final prices that are significantly higher than the starting price.

4. Auction Trends: Since the coin has sold every time it has been auctioned, this indicates a consistent interest in the coin, which may influence its price.

Based on these factors, we can make an estimation. Given that the current condition is 75 and considering that in the past final prices of up to 6500 euros have been reached for higher conditions, a reasonable maximum purchase price could be between the average final price (4500 euros) and the highest final price (6500 euros).

Therefore, an estimated maximum purchase price could be around 5500 euros. This reflects a balance between the current condition and historical prices, taking into account that the coin is not in the best possible condition.

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

1. Current Condition: The coin has a condition rating of 75 (VF), indicating that it is in quite good shape. This generally translates to a higher price compared to coins in lower conditions.

- The coin has been auctioned 10 times, of which it has sold 9 times, indicating good demand.
- Previous hammer prices for coins with similar conditions (70-75) have varied, but the range seems to be between 160 and 350 euros in the most recent auctions.

3. Starting Price: The current starting price is 300 euros, which is a reasonable starting point.

4. Price Trends: Looking at previous hammer prices, it appears that coins with a condition of 70-75 have reached hammer prices ranging from 160 to 350 euros. However, since this coin's condition is 75, it is reasonable to expect that the hammer price will be at the upper end of this range.

5. Final Estimate: Considering all these factors, an estimated maximum purchase price could be around 400-450 euros. This is based on the good condition of the coin and the hammer price history for similar coins.

Therefore, an estimated maximum purchase price for this coin could be 450 euros.

2. Average hammer price in the past: 261.67 euros.
3. Previous hammer prices:
- The highest auction was 900 euros (condition 50).
- The lowest auction was 25 euros (condition 25).
- There are several auctions with hammer prices between 50 and 550 euros, with varying conditions.

4. Condition: There is no information about the condition of this coin, which makes the estimation more uncertain. However, observing the conditions of previously auctioned coins, it can be noted that coins in better condition tend to reach higher prices.

5. Trends:
- The general trend shows that hammer prices can be significantly lower than the current starting price, especially if the condition is unknown.
- The average hammer price of 261.67 euros suggests that the starting price of 700 euros is quite high compared to what has been sold previously.

### Estimation of the maximum purchase price:
Given that the starting price is 700 euros and considering that the average hammer price is 261.67 euros, a reasonable maximum purchase price could be in the range of 300 to 400 euros, assuming that the buyer is willing to pay a little more than the average due to the uncertainty in the condition.

Therefore, an estimated maximum purchase price could be approximately 400 euros. This allows the buyer to take into account the possibility that the coin may have a higher than expected condition value, but also reflects the reality of previous hammer prices.

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

1. Condition: The coin to be auctioned has a condition of 85 (ebc-). This is an important factor, as coins in better condition tend to fetch higher prices.

2. Previous auction prices: By analyzing the hammer prices of coins with similar conditions (85 and 95), we can observe that coins with a condition of 95 have reached hammer prices between 3400 and 4000 euros. The last auction of a coin with a condition of 85 had a hammer price of 2600 euros.

3. Average hammer price: The average hammer price for this particular coin is 2980 euros, indicating that, in general, coins of this reference tend to sell within that range.

4. Starting price: The starting price is 1800 euros, which may attract more bidders, but it can also indicate that the seller is looking for a quick sale.

5. Market trends: Since the coin has been auctioned 10 times and all have been sold, this suggests a consistent demand.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 2800 to 3200 euros. This is based on the average hammer price and the condition of the coin. Therefore, a reasonable maximum purchase price could be 3200 euros.

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

4. Hammer price history: Hammer prices have varied, with some reaching up to 3300 euros in previous auctions, although most have sold in a lower range.

Since there is no information about the condition of the current coin, it is difficult to make a direct comparison. However, we can observe that:

- Most coins with higher conditions (above 80) have had hammer prices ranging between 1500 and 2500 euros, with some exceptional cases reaching higher prices.
- The last auction with a hammer price of 4700 euros was conducted with a condition of 100, indicating that the quality of the coin has a significant impact on the price.

Taking these factors into account, an estimated maximum purchase price could be set in a range between the average hammer price (1900.65 euros) and the highest observed price (3300 euros), depending on demand and the quality of the coin.

Estimated maximum purchase price: 2500 euros.

This price reflects a balance between the price history and the uncertainty regarding the current condition of the coin.
