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: 300 euros.
2. Average hammer price in the past: 316.8 euros.
3. Previous hammer prices:
- In several auctions, hammer prices have ranged from 250 to 420 euros, with a notable hammer price of 500 euros in a recent auction.
4. Condition: There is no specific information about the condition of this coin, which may affect its value. However, there have been previous auctions with conditions of 95 and 100 that have reached high hammer prices.

Given that the average hammer price is 316.8 euros and considering that recent auctions have reached hammer prices of up to 500 euros, an estimated maximum purchase price could be set in a range above the average hammer price, but not as high as the historical maximum, especially since there is no information on the condition.

Estimated maximum purchase price: 400 euros.

This price reflects a balance between the average hammer price and the higher prices reached in previous auctions, taking into account the lack of information about the current condition of the coin.

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

1. Starting Price: 500 euros. This is the initial price set for the auction.
2. Auction History: The coin has been auctioned 2 times in the past, of which it has sold 1 time. This indicates moderate interest in the coin.
3. Average Starting and Hammer Price: The average starting price in the past is 270 euros, and the average hammer price is 650 euros. This suggests that, although the current starting price is higher, interest in the coin may lead to a higher hammer price.
4. Condition: There is no information about the current condition of the coin, which may make bidders more cautious. However, the previous hammer price of 70 euros for a coin with a condition of 20 suggests that interest may vary depending on the condition.
5. Previous Prices: In the last auction, the starting price was 40 euros, indicating that interest and the value of the coin have increased over time.

Given that the current starting price is 500 euros, which is significantly higher than the previous average starting price, and considering that the average hammer price is 650 euros, we could estimate that the maximum purchase price could be in a range between the starting price and the average hammer price.

Taking all these factors into account, an estimated maximum purchase price could be approximately 600 euros. This is based on historical interest and the potential for bidding, but it also considers the lack of information about the current condition, which could limit bidder interest.

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.
3. Average starting and hammer price: The average starting price is 300 euros and the average hammer price is 700 euros. This suggests that, in general, coins of this reference tend to reach higher prices at auctions.
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 can analyze the provided data, especially the previous auction prices and the conditions of the auctioned coins.

1. Starting price: 350 euros.
2. Times it has been auctioned in the past: 92.
3. Times it has sold in the past: 84.
4. Average hammer price: 167.6 euros.

- Coins with higher conditions (95) have reached significantly higher hammer prices (up to 2000 euros).
- The majority of hammer prices are in the range of 80 to 370 euros, with an average of 167.6 euros.

Given that the starting price is 350 euros, which is relatively high compared to the average hammer price, and considering that there is no information on the condition of the coin, an estimated maximum purchase price could be slightly lower than the starting price, given the risk of not reaching that value at auction.
