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 Listing Price and Previous Prices: The current listing price is 150 euros. In previous auctions, the highest hammer price for a coin with a similar condition (95) was 170 euros in 2018. However, lower hammer prices have also been observed in other auctions.

3. Sales Trends: Out of the 23 times it has been auctioned, it has sold 17 times, indicating good demand. The average hammer price in previous auctions is 88.59 euros, but this includes coins of different conditions.

4. Estimated Price: The estimated price for the current auction is 300 euros, suggesting that there are expectations for the coin to reach a higher price due to its condition.

5. Comparison with Historical Prices: Considering that a condition rating of 95 is quite high and that the highest hammer price in the past was 170 euros, it is reasonable to think that the price could be in a higher range than in previous auctions.

Taking all these factors into account, an estimated maximum purchase price could be between 200 and 250 euros. This is based on the good condition of the coin and the price trends in previous auctions, as well as the current estimated price.

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

1. Starting price: 200 euros.
2. Average hammer price: 278.35 euros.
3. Previous hammer prices:
- Similar coins with conditions ranging from 80 to 95 have sold for prices varying from 51 euros to 1400 euros.
- The most recent auction had a hammer price of 650 euros and a condition of 85.
- The 2022 auction had a hammer price of 400 euros and a condition of 95.

4. Condition: No specific information is provided about the condition of the current coin, making the estimation more complicated. However, we can observe that coins with higher conditions tend to reach significantly higher hammer prices.

5. Trends:
- Coins with conditions from 80 to 95 have had hammer prices ranging from 130 to 1400 euros.
- The general trend shows that the hammer price can be considerably higher than the starting price.

Given that there is no information about the condition of the current coin, but considering that the starting price is 200 euros and the average hammer price is 278.35 euros, an estimated maximum purchase price could be set at a higher range, considering previous auctions.

Estimated maximum purchase price: Based on the data, a reasonable maximum purchase price could be between 400 to 500 euros, as this range has been reached in previous auctions with similar conditions. However, if the condition is high, the price could be even higher.

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

1. Current Condition: The coin has a condition of 90 (XF), which indicates that it is in quite good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Historical Prices: By looking at previous auction prices for coins with similar conditions, we can see that:
- In 2018, a coin with a condition of 95 sold for 1700 euros.
- In 2019, a coin with a condition of 90 sold for 650 euros.
- In 2022, a coin with a condition of 85 sold for 400 euros.

3. Starting Price and Average Hammer Price: The current starting price is 300 euros, and the average hammer price in the past has been 284.88 euros. This suggests that the starting price is reasonable, but it also indicates that the hammer price may be lower than the starting price.

4. Sales Trends: The coin has sold in 33 out of the last 36 auctions, indicating good demand.

Based on these factors, an estimated maximum purchase price could be in the range of 600 to 800 euros, considering that the condition is good and there are precedents for sales at higher prices for coins in similar conditions. However, since the starting price is 300 euros, it is likely that the hammer price will not significantly exceed this value unless there is strong competition in the auction.

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 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.

- 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 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. Auction History:
- The average hammer price for this coin is 153.52 euros.
- In previous auctions, we have seen hammer prices that varied significantly, with some reaching up to 1000 euros in exceptional conditions (such as in 2018 with a condition of 95).
- Recent trends show that hammer prices have been in the range of 130 to 380 euros for similar conditions.

3. Starting Price: The current starting price is 150 euros, which is a good indicator of the seller's expectations.

4. Demand and Supply: The coin has been auctioned 44 times, with a sell-through rate of 88.6% (39 out of 44). This suggests that there is consistent interest in this coin.

5. Recent Hammer Prices: The most recent hammer prices for coins with similar conditions (85-90) have been in the range of 260 to 380 euros.

Based on these factors, an estimated maximum purchase price for this coin could be between 300 and 380 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate.

Therefore, a reasonable maximum purchase price could be 350 euros.

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 85 (ebc-), indicating that it is in quite good shape. This is important because coins in better condition tend to fetch higher prices at auctions.

2. Auction History:
- The average hammer price for this coin in the past is 277.78 euros.
- Previous hammer prices have varied, with a maximum of 700 euros in a recent auction (2022) and a minimum of 84 euros.
- Most of the time, the coin has sold for above its starting price, indicating consistent demand.

3. Current Starting Price: The starting price is 200 euros, which is slightly higher than the average starting price of 107.22 euros, but this can be justified by the coin's condition.

4. Price Trends: Looking at previous hammer prices, it seems that coins in similar conditions have reached hammer prices ranging from 230 to 700 euros, depending on the condition and demand at the time of the auction.

5. Estimation: Given that the coin's condition is rated at 85 and considering the price history, an estimated maximum purchase price could be in the range of 300 to 400 euros. This is based on the fact that the coin has reached hammer prices above 300 euros on several occasions and that the current condition is favorable.

Therefore, an estimated maximum purchase price for this coin could be 350 euros.

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

1. Current starting price: 3500 euros.
2. Coin condition: 90 (EBC), indicating good preservation.
3. Auction history:
- In 2018, the coin was auctioned with a starting price of 900 euros and sold for 15500 euros, with a condition of 90.
- In 2022, it was auctioned with a starting price of 400 euros and sold for 1600 euros, with a condition of 80.
- In 2023, it was auctioned with a starting price of 100 euros and sold for 260 euros, with a condition of 30.
- In 2023, another auction had a starting price of 300 euros and sold for 1200 euros, with a condition of 80.

4. Average hammer price: 4962 euros, indicating that, in general, coins of this reference tend to reach higher prices at auction.

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. Condition of the coin: The coin to be auctioned has a condition rating of 90 (EBC), 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 previous prices: The starting price is 400 euros. The average hammer price in previous auctions for this coin is 458.94 euros, suggesting that, in general, coins of this reference tend to sell for above their starting price.

3. Auction history: In the auction history, it is observed that coins with similar conditions have reached hammer prices that vary considerably, but there are examples of coins that have sold for significantly higher prices, especially those with superior conditions.

4. Recent trends: In the most recent auctions, hammer prices have been quite high, which could indicate an upward trend in interest for this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 600 to 800 euros. This is based on the fact that the condition is good and that the price history shows that similar coins have reached hammer prices in that range. However, since the starting price is 400 euros, it is likely that the hammer price will not significantly exceed this range unless there is strong 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 will consider several factors:

1. Condition of the coin: The coin to be auctioned has a condition rating of 90 (EBC), indicating that it is in very good condition. This generally translates to a higher price compared to coins with lower condition ratings.

2. Price history: By looking at previous auction prices for coins with a similar condition (90), we find that they have sold for prices that varied considerably in the past. For example:
- In 2019, a coin with a condition of 90 sold for 2000 euros.
- In 2020, another coin with a condition of 90 sold for 500 euros.
- In 2022, a coin with a condition of 85 sold for 1100 euros.

3. Starting price and average hammer price: The current starting price is 700 euros, and the average hammer price in previous auctions is 632.55 euros. This suggests that the starting price is reasonable and could attract bidders.

4. Market trends: Given that the coin has a history of successful sales and has reached high prices in the past, it is reasonable to assume that interest in this coin could be high, especially if the condition is good.

Based on these factors, an estimated maximum purchase price could be in the range of 1000 to 1500 euros, considering that the highest hammer price in the past was 2000 euros, but also taking into account that the average hammer price is significantly lower.

Therefore, a reasonable maximum purchase price could be 1200 euros.

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

1. Starting price: 1000 euros.
2. Current grade: 80 (MS+). This indicates that the coin is in good condition, although not the best.
3. Auction history: The coin has been auctioned 2 times in the past, and both times it has sold. In the 2019 auction, the hammer price was 10,000 euros, despite the starting price being 1,000 euros. This suggests that there is significant interest in this coin.
4. Average hammer price: 5650 euros, indicating that, in general, coins of this reference tend to reach high prices at auction.

Given that the current grade is 80 and considering the previous hammer price of 10,000 euros for a coin in better condition (95), we can make an estimation.

We can assume that the hammer price could be proportional to the grade. If a coin in grade 95 sold for 10,000 euros, we could estimate that a coin in grade 80 could reach a lower, but still significant, price.

One way to calculate this is to consider the difference in grade. The difference between 95 and 80 is 15 points. If we assume that each point of grade has a proportional value, we could estimate that the hammer price for the coin in grade 80 could be around 60-70% of the hammer price of the coin in grade 95.

Therefore, an estimated maximum purchase price could be in the range of 6,000 to 7,000 euros, considering the interest in the coin and its auction history.

Maximum purchase estimate: 6,500 euros.

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

1. Current Condition: The coin is in a condition of 90 (EF), which indicates that it is in quite good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Starting Price and Previous Prices: The current starting price is 700 euros, and the average hammer price in previous auctions is 707.62 euros. This suggests that the starting price is reasonable and that there is a good chance it will sell for a similar or higher price.

3. Sales History: The coin has been auctioned 45 times, of which 42 have resulted in sales. This indicates a consistent interest in the coin, which can positively influence its price.

4. Previous Hammer Prices: Looking at previous hammer prices, there are examples of sales that have reached significantly higher prices, especially in similar conditions. For instance, in 2011, a coin with a condition of 90 sold for 1200 euros.

5. Recent Trends: In recent auctions, hammer prices have varied, but there are examples of similar coins that have sold for prices exceeding 1000 euros.

Based on these factors, an estimated maximum purchase price for this coin could be between 1000 and 1200 euros, considering its good condition and the demonstrated interest in previous auctions. However, since the starting price is 700 euros, it is likely that buyers will be willing to bid beyond this price, especially if there is competition in the auction.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the current condition of the coin (95, EBC+) and the hammer prices from previous auctions.

1. Condition: The coin has a condition of 95, indicating that it is in very good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Previous hammer prices: Looking at the hammer prices of coins with similar conditions:
- In 2019, a coin with a condition of 90 sold for 4200 euros.
- In 2020, a coin with a condition of 70 sold for 320 euros.
- In 2014 and 2015, coins with a condition of 75 sold for 187.21 and 184.48 euros, respectively.

3. Average hammer price: The average hammer price of coins auctioned in the past is 895.63 euros, which can also serve as a reference.

4. Starting price: The current starting price is 1500 euros, indicating that the seller has expectations of a higher price.

Given that the condition of the coin is quite high (95), and considering the hammer prices of coins with lower conditions, it can be estimated that the hammer price could be in a higher range.

Estimated maximum purchase price: Based on the condition and previous hammer prices, a reasonable maximum purchase price could be between 2000 and 3000 euros. This is because, although the starting price is 1500 euros, the high condition and previous hammer prices suggest that it could reach a significantly higher price at auction.

Therefore, an estimated maximum purchase price could be 2500 euros.
