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 coin.

1. Starting price: 300 euros.
2. Average auction price: 121.29 euros.
3. Auction price history:
- Previous auction prices varied significantly, with some reaching up to 390 euros in the case of unspecified condition.
- Most auction prices ranged between 40 and 300 euros, depending on the condition.

4. Condition: No information is provided about the current condition of the coin, making the estimation more complicated. However, by observing the auction prices of coins with similar conditions (around 70-90), we can infer that the price could be in a mid-range.

5. Analysis of previous prices:
- The coin has had successful auctions in the past, with prices ranging from 35 to 390 euros.
- The trend shows that coins with conditions of 70 to 90 have reached auction prices between 60 and 300 euros.

Given that there is no information about the current condition, and considering the starting price of 300 euros, an estimated maximum purchase price could be in the range of 200 to 300 euros, depending on demand and collector interest at the time of the auction.

Maximum purchase estimate: 250 euros. This is based on the analysis of previous prices and the lack of information about the current condition.

To estimate a maximum purchase price for the coin that is going to be auctioned, we can analyze the provided data. Here are some key points to consider:

1. Starting price: 250 euros.
2. Average hammer price: 114.8 euros.
3. Auction history: The coin has been auctioned 31 times, of which it has sold 30 times. This indicates good demand.
4. Previous prices: Previous hammer prices varied, but there are examples of auctions reaching up to 300 euros in higher conservation conditions (such as in the auction on 2022-03-30).

Since there is no information about the conservation of the current coin, it is difficult to make an accurate estimate. However, we can consider the starting price and the history of hammer prices.

- The starting price of 250 euros is significantly higher than the average hammer price of 114.8 euros, suggesting that the seller has high expectations for the coin.
- If we consider the highest recorded hammer price (300 euros), this could be a good indicator of a maximum purchase price, especially if the coin has acceptable conservation.

Taking these factors into account, an estimated maximum purchase price could be between 250 and 300 euros, depending on the conservation and demand at the auction. However, since the starting price is 250 euros, a reasonable maximum price could be approximately 275 euros. This allows for some competition in the auction while also remaining below the starting price.

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

1. Current starting price: 700 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 can analyze the provided data, including the starting and hammer prices from previous auctions, as well as the condition of the coins.

1. Current starting price: 150 euros.
2. Average hammer price in the past: 111.84 euros.
3. Previous hammer prices:
- They have sold for prices ranging from 20 euros to 550 euros, depending on the condition.
- Coins in high condition (95-100) have reached hammer prices of up to 550 euros.
- Coins in average condition (75-85) have had hammer prices ranging between 40 and 110 euros.

4. Condition of the coin: There is no information about the condition of this coin, which makes the estimation more uncertain.

5. Price trends:
- Coins that have had a starting price of 150 euros in the past have had hammer prices that vary, but some have reached up to 420 euros.
- The general trend shows that hammer prices can be significantly higher than the starting price, especially if the condition is good.

Given that there is no information about the condition of this coin, and considering that the starting price is 150 euros, an estimated maximum purchase price could be in the range of 200 to 300 euros, assuming the coin has an acceptable condition and that there is high interest in the auction.

Therefore, an estimated 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 condition of the auctioned coins.

1. Current starting price: 400 euros.
2. Average auction price in the past: 176.44 euros.
3. Previous auction prices:
- The coin has had auctions that varied from 24 euros to 650 euros, depending on the condition.
- The conditions of the auctioned coins in the past have varied, with some reaching conditions of 95, indicating high quality.

4. Condition of the current coin: There is no information about the condition of this coin, which complicates the estimation. However, we can observe that coins with higher conditions have reached significantly higher auction prices.

5. Price trends:
- The general trend shows that coins with higher conditions tend to achieve higher auction prices. For example, a coin with a condition of 95 was auctioned for 650 euros.
- Most auctions have been below 200 euros, suggesting that the average auction price is a good indicator for setting a limit.

Given that the starting price is 400 euros, which is considerably higher than the previous average auction price, and without information about the condition, an estimated maximum purchase price could be set in a more conservative range.

Estimated maximum purchase price: Based on the average auction price and the variability of previous prices, a reasonable maximum purchase price could be between 200 and 250 euros, assuming that the condition is not exceptional. If it is considered that the coin might have a high condition, the price could approach 300 euros, but without clear information, it is better to be conservative.

Therefore, an estimated maximum purchase price could be 250 euros.

4. Estimation:
- Given that the average hammer price is 104.13 euros and considering that the starting price is 150 euros, it is reasonable to assume that the hammer price could be in a higher range due to demand or the quality of the coin.
- Based on previous hammer prices and the starting price, an estimated maximum purchase price could be between 150 and 200 euros, considering that the starting price is an indicator of the sellers' expectations.

Therefore, an estimated maximum purchase price for this coin could be 200 euros.

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 95 (EF+), indicating that it is in very 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 600 euros. The average hammer price in previous auctions is 364.14 euros, suggesting that the current starting price is quite high compared to the historical average.

3. Price Trends: By observing the hammer prices of coins with similar conditions (95), we can see that they have reached hammer prices of up to 550 euros in recent auctions. However, there are also examples of coins that have sold for over 600 euros, especially if demand is high.

4. Sales History: The coin has been auctioned 41 times, of which 36 have been sold. This indicates a good sales rate, which may be an indicator of interest in the coin.

5. Comparison with Previous Prices: In previous auctions, coins with a condition of 95 have had hammer prices that vary, but some have reached up to 500-550 euros.

Taking all these factors into account, an estimated maximum purchase price could be between 600 and 700 euros, considering that interest in the coin may lead bidders to be willing to pay a bit more than the starting price. However, since the starting price is already 600 euros, a realistic hammer price could be closer to 650 euros, assuming that demand remains steady.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on 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. Current and Previous Prices: The current starting price is 300 euros. In previous auctions, we have seen hammer prices that vary significantly, but there are examples of hammer prices exceeding 500 euros for coins with similar conditions.

3. Price Trends: The average hammer price for coins of this reference is 348.13 euros, suggesting that the hammer price may be higher than the current starting price.

4. Recent Auction Hammer Prices: In the most recent auctions, we have seen hammer prices reaching up to 1600 euros for coins with similar conditions (as in the auction on March 14, 2024).

5. Estimation Based on Average Hammer Price: Given that the average hammer price is 348.13 euros and considering the good condition of the coin, an estimated maximum purchase price could be in the range of 500 to 600 euros, especially when considering the price trends in recent auctions.

Conclusion: Based on all these factors, an estimated maximum purchase price for the coin could be approximately 600 euros. This would allow for effective competition in the auction, considering the good condition and the history of hammer prices.

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

1. Current Condition: The coin has a condition of 90 (EF), which indicates 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 similar coins in the past is 348.13 euros.
- The last auction of a coin with a similar condition (90) was sold for 550 euros (auction date: 2018-10-17).
- In recent auctions, hammer prices have varied, but there are examples of coins with conditions of 85 and 95 that sold for 320 and 1600 euros, respectively.

3. Starting Price: The starting price of 500 euros is a good indicator of the seller's expectations, but it does not necessarily reflect the final hammer price.

4. Market Trends: Given that the coin has been auctioned 47 times and has had a high sales percentage (44 out of 47), this suggests there is consistent interest in this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 600 to 800 euros, considering that the condition is high and there are precedents for successful sales in that range. However, given the starting price of 500 euros, it is possible that the final hammer price may not significantly exceed this value unless there is active competition among bidders.

Therefore, a reasonable maximum purchase price could be 700 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 general trend of the 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.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, including auction history and previous hammer prices.

1. Current Condition: The coin has a condition rating of 85 (ebc-), indicating that it is in quite good shape. This is relevant because coins in better condition tend to fetch higher prices.

- The condition of the coins in previous auctions varies, but those with higher condition (like 90) achieve significantly higher prices.

4. Estimation:
- Given that the current starting price is 3000 euros and considering that in previous auctions hammer prices have reached up to 9500 euros, an estimated maximum purchase price could be positioned in a range between the starting price and the average hammer price.
- Taking into account the history and the average hammer price, a reasonable maximum purchase price could be around 7000 euros, which is the estimated price from the most recent auction with a starting price of 3000 euros.

Therefore, the estimated maximum purchase price for this coin could be 7000 euros.

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

1. Current starting price: 150 euros.
2. Auction history: The coin has been auctioned 2 times in the past, and on both occasions, it was sold. This indicates interest in the coin.

4. Condition: There is no information about the current condition of the coin, but in the previous auction, a coin with a condition value of 75 sold for 750 euros. This indicates that if the condition is similar or better, the price could be high.
5. Price trends: Given that the previous hammer price was 750 euros, this sets a high benchmark.

Since the current starting price is significantly lower than the average hammer price and the previous hammer price, and considering that the coin has a good sales history, an estimated maximum purchase price could be positioned in a range between the average hammer price and the previous hammer price.

Estimated maximum purchase price: It could be reasonable to consider a maximum purchase price of around 700 to 750 euros, assuming that the condition is at least similar to that of the previous auction. However, since there is no information about the current condition, a more conservative approach could be to set a limit around 600 euros to avoid overpaying if the condition is not favorable.

Therefore, an estimated maximum purchase price could be 700 euros.

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 in lower condition.

2. Auction History:
- The average hammer price for similar coins in the past is 244 euros.
- The last auction of a coin with a similar condition (90) had a hammer price of 500 euros, suggesting that there is significant interest in high-quality coins.

3. Starting Price: The starting price is 300 euros, which may influence the final price, as buyers often consider the starting price as an indicator of the coin's value.

4. Price Trends: In previous auctions, we have seen hammer prices that varied considerably, but coins in better condition tend to reach higher prices. For example, in the 2023 auction, a coin with a condition of 85 sold for 500 euros.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 400 to 600 euros, considering its good condition and the interest shown in previous auctions. A more conservative price could be around 450 euros, while a more optimistic price could reach up to 600 euros, depending on the competition in the auction.
