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

1. Condition: The coin has a condition of 70 (MBC-), which indicates that it is in relatively good shape, but not of the highest quality. This may influence its value.

2. Previous auction prices:
- In 2014, the coin was offered with a starting price of 1200 euros, but no final price was recorded, suggesting that it did not sell.
- In 2016, the starting price was 160 euros, with an estimated price of 200 euros and a final price of 450 euros. This indicates that, despite a lower starting price, the coin sold for a considerably higher price.

3. Average starting and final prices: The average starting price is 475 euros and the average final price is 450 euros. This suggests that, in general, coins of this reference tend to reach final prices close to these values.

4. Current auction situation: The coin has a starting price of 65 euros, which is significantly lower than previous starting prices. This could attract more bidders and potentially increase the final price.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 400 to 600 euros, considering that the condition is good and there is a history of final prices suggesting that the coin may reach a higher value in the current auction.

Therefore, a reasonable maximum purchase price could be approximately 500 euros.

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

1. Starting Price: 100 euros. This is the initial price set for the auction.
2. Condition: The coin has a condition rating of 70 (MBC-), indicating that it is in fairly good condition, but not of the highest quality (FDC).
3. Auction History: The coin has been auctioned once in the past but did not sell, which may indicate that interest or demand for this particular coin is not very high.
4. Average Hammer Price: There are no data on previous sales, making it difficult to establish an average hammer price.

Given that the coin has a condition rating of 70 and considering that it did not sell in the previous auction, it is likely that interest in the coin is not very high. However, since the starting price is 100 euros, we could estimate that the maximum purchase price might be in a range close to this price, but not necessarily reaching it.

Taking all these factors into account, an estimated maximum purchase price could be around 80-90 euros. This would allow a potential buyer to consider the condition and auction history without risking paying the full starting price, given that there is no guarantee that the coin will sell this time.

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 relatively 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 60 euros, and the average hammer price in previous auctions is approximately 77.87 euros. This suggests that the hammer price tends to be above the starting price.

3. Sales History: The coin has been sold in 26 out of the 43 previous auctions, indicating reasonable demand. Additionally, the highest recorded hammer price in the past was 150 euros for a coin with a condition rating of 90.

4. Recent Trends: In the most recent auctions, hammer prices have ranged from 55 to 85 euros, suggesting that interest in this coin remains steady.

Based on these factors, an estimated maximum purchase price could be in the range of 85 to 100 euros. This is because, given the condition and price history, it is reasonable to expect that a collector would be willing to pay a bit more than the previous average hammer price, especially if the coin is in good condition.

Therefore, an estimated maximum purchase price could be 95 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 70 (VF-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Auction History:
- The coin has been auctioned 8 times, of which it has sold 5 times. This indicates that there is interest in the coin, although there is also a 37.5% chance that it has not sold.
- Previous hammer prices varied, but there are examples of hammer prices reaching up to 1600 euros (in 2016).

3. Average Starting and Hammer Prices:
- The average starting price is 732.64 euros and the average hammer price is 1067.66 euros. This suggests that, in general, coins of this reference tend to sell above the starting price.

4. Previous Prices:
- Previous hammer prices for coins with similar conditions (75 and 90) have reached up to 1482.87 euros. However, the condition of 70 is lower than those examples, suggesting that the hammer price could be lower.

5. Market Trends: Since it will not be auctioned in the coming days, this could increase demand in the future, which could influence the price.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 600 to 800 euros, considering that the condition is not the best and that the starting price is 80 euros. However, given the history of hammer prices, a reasonable maximum purchase price could be approximately 800 euros.

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

1. Starting Price: 100 euros. This is the initial price set for the auction.
2. Condition: The coin has a condition rating of 85 (ebc-), indicating that it is in fairly good shape. This generally increases its value compared to coins in lower condition.
3. Auction History: The coin has been auctioned 2 times in the past, of which it sold 1 time and did not sell 1 time. This suggests that there is interest in the coin, but also that there may be a limit to what buyers are willing to pay.
4. Previous Prices: In the 2015 auction, the starting price was 39.91 euros and the final price was the same, indicating that there was no significant increase in price on that occasion.

Given that the current starting price is 100 euros, which is considerably higher than the previous final price, and considering the condition of the coin, an estimated maximum purchase price could be in a range between the starting price and the average final price of previous auctions.

Taking all these factors into account, an estimated maximum purchase price could be approximately 70-80 euros. This is based on the potential interest of buyers, the condition of the coin, and the price history.

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

1. Starting Price: 75 euros. This is the initial price of the auction.
2. Condition: The coin has a condition rating of 70 (VF-), indicating that it is in acceptable but not excellent condition. This may affect its value compared to coins in better condition.
3. Auction History: The coin has been auctioned 3 times in the past, of which it has sold 2 times. This suggests that there is interest in the coin, although there is also one instance where it did not sell.
4. Previous Prices: In previous auctions, the starting price was 120 euros and the final price was 130 euros. This indicates that, despite a higher starting price, buyer interest translated into a final price that was not significantly higher than the starting price.

Given that the average final price in the past has been 130 euros and considering the condition of the coin, an estimated maximum purchase price could be positioned between the starting price and the average final price.

Taking all these factors into account, an estimated maximum purchase price could be approximately 100-110 euros. This reflects moderate interest, given the auction history and the condition of the coin.
