Given that the coin has a conservation rating of 80 (MBC+), which indicates good quality, and considering that this is the first time it is being auctioned, the starting price is set at 90 euros.

Without historical sales data for this reference, it is difficult to establish a maximum estimated purchase price based on past trends. However, since the starting price is 90 euros and the conservation is good, we could estimate that the final price could be in a range of 90 to 120 euros, depending on the interest from collectors and the competition in the auction.

Therefore, a maximum estimated purchase price could be around 120 euros, assuming there is moderate interest in the coin.

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 30 (BC+), which indicates that it is not in very good shape. This generally reduces its value compared to coins in better condition.

- Given that the condition is 70, and considering that in the past similar condition coins have sold for hammer prices around 158 euros (in 2019) and 120 euros (in 2014), we can infer that the hammer price could be in a similar range.

With all this in mind, an estimated maximum purchase price could be around 180-200 euros, assuming that interest in the coin remains and that the condition does not hinder a good auction result. However, since the starting price is 120 euros, it could be a good opportunity to acquire it at a price lower than the estimated.

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 70 (MS-), indicating that it is in an acceptable state, but not of the highest quality.

2. Auction History:
- The average hammer price for coins of similar condition (70) in the past has been approximately 45-65 euros.

- The estimated price of 25 euros in a previous auction with a similar condition is also relevant.

4. Demand and Supply: The coin has been auctioned 6 times in the past, of which 5 have sold. This indicates a consistent interest in the coin, which may increase its value.

Taking all these factors into account, a reasonable maximum purchase price could be in the range of 30 to 40 euros, considering that the condition is not optimal and that the highest hammer price in the past was 81 euros for a better condition.

Therefore, an estimated maximum purchase price could be 35 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 rating of 70 (VF-), indicating that it is in relatively good shape, but not the best possible condition.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 80 to 100 euros. This is based on the current condition, previous auction prices, and recent market trends.

Therefore, a reasonable maximum purchase price could be 90 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 rating of 80 (MBC+), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

4. Auction Trends: The coin has been auctioned 13 times, of which 12 have sold. This indicates a consistent interest in the coin, which may increase its value in the current auction.

5. Starting Price and Estimates: The starting price is 30 euros, and the average starting price is 33.58 euros. However, given that the condition is good and there is interest in the coin, it is reasonable to expect that the final auction price will be significantly higher.

Based on these factors, an estimated maximum purchase price could be in the range of 90 to 120 euros. This is based on the fact that in previous auctions, coins with similar conditions have reached final prices of up to 140 euros. Therefore, a prudent maximum purchase price could be 100 euros.

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

1. Starting Price: 30 euros. This is the initial price set for the auction.
2. Condition: The coin has a condition rating of 70 (VF-), indicating that it is in fairly good shape. This can generally increase its value compared to coins in lower condition.
3. Auction History: The coin has been auctioned once before, with a hammer price of 15 euros. This suggests that, despite a starting price of 30 euros, market interest may not be as high as expected.
4. Average Hammer Price: The average hammer price of 15 euros also indicates that, in general, buyers are willing to pay less than the current starting price.

Given that the coin has a relatively good condition (70) and considering the auction history, an estimated maximum purchase price could be slightly higher than the previous hammer price, but not as high as the current starting price.

Taking all these factors into account, an estimated maximum purchase price could be around 20-25 euros. This reflects moderate interest, given the auction history and the condition of the coin.

4. Average hammer price: 42.67 euros, suggesting that, in general, coins of this reference tend to sell above the starting price.

Given that the coin has a history of sales exceeding the current starting price and considering that the condition is the same as in the 2020 auction, an estimated maximum purchase price could be around 45 euros, which is the highest price reached in the past for a coin with the same condition.

Therefore, an estimated maximum purchase price for this coin could be 45 euros.
