Given that the coin has a condition of 75 (MBC) and has not been auctioned or sold in the past, the starting price is 75 euros.

Without historical sales data for this reference, it is difficult to establish a maximum estimated purchase price. However, considering that the starting price is 75 euros and that the condition is good (MBC), you could consider a maximum estimated purchase price that could be in the range of 1.5 to 2 times the starting price, depending on collector interest and demand at the auction.

Therefore, a maximum estimated purchase price could be between 100 and 150 euros. This is just an estimate, and the actual price may vary according to the dynamics of the auction.

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 85 (ebc-), indicating that it is in fairly good shape. This suggests that its value should be above that of coins in worse conditions.

2. Previous Prices: By looking at previous auction prices, we can see that coins with similar conditions have reached auction prices that vary significantly. For example:
- A coin with a condition of 95 was auctioned for 800 euros.
- A coin with a condition of 90 was auctioned for 180 euros.
- A coin with a condition of 85 was auctioned for 75 euros (although the auction price of the last auction is not available).

3. Average Auction Price: The average auction price for this coin is 171.88 euros, which is also an important indicator.

4. Starting Price and Average Starting Price: The starting price is 60 euros, and the average starting price is 78 euros. This suggests that interest in the coin may be moderate, but not necessarily low.

5. Auction Trends: Given that there have been 10 previous auctions and all have resulted in sales, this indicates a consistent interest in the coin.

Based on these factors, an estimated maximum purchase price could be in the range of 150 to 200 euros, considering that the condition is good and the average auction price is 171.88 euros. However, since the condition is lower than the highest ratings, a more conservative price could be around 150 euros.

Therefore, a reasonable estimated maximum purchase price could be 150 euros.

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

1. Starting price: 60 euros.
2. Average hammer price in the past: 65 euros.
3. Condition of the coin: 70 (MBC-), which indicates good condition, although not the best.
4. Auction history: It has been auctioned once in the past and sold on that occasion, suggesting there is interest in the coin.

Given that the average hammer price in the past was 65 euros and considering that the condition of this coin is good (70), it is reasonable to think that the hammer price could be in a similar range or slightly higher, especially if there is interest in the current auction.

Taking all these factors into account, an estimated maximum purchase price could be between 70 and 80 euros. This is based on the fact that the condition is good and that interest in the coin could lead to a hammer price higher than the previous average.

Therefore, an estimated maximum purchase price could be 75 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 85 (ebc-), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Previous Prices: By looking at previous auction prices for coins with a similar condition (85), we find that in past auctions, the hammer prices have varied. For example:
- In the auction on December 16, 2020, the coin with a condition of 85 sold for 100 euros.
- In the auction on February 16, 2023, it sold for 75 euros, but the estimated price was 125 euros.

3. Average Hammer Price: The average hammer price for this coin is 80.34 euros, which can also serve as a reference.

4. Starting Price: The current starting price is 75 euros, indicating that the seller expects a minimum price of 75 euros.

5. Sales Trends: The coin has been auctioned 46 times, of which 32 have resulted in sales. This suggests that there is consistent interest in this coin.

Based on these factors, an estimated maximum purchase price could be between 100 and 125 euros, given that this range has been reached in previous auctions for coins with a similar condition. Therefore, a reasonable maximum purchase price could be:

Estimated maximum purchase price: 125 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 (MS+), which is quite good. This suggests that its value should be in the upper range of previous auctions.

2. Previous Auction Prices:
- The average hammer price for coins of similar condition (80) has been 114.38 euros.
- In previous auctions, hammer prices for coins with a condition of 80 have varied, but some examples are:
- 180 euros in December 2020.
- 150 euros in October 2020.
- 120 euros in January 2019.
- 295 euros in September 2017 (although this last one may be an exceptional case).

3. Current Starting Price: The starting price is 90 euros, indicating that the auctioneer expects moderate interest in the coin.

4. Sales Trends: The coin has been sold in 38 out of the last 45 auctions, indicating good demand.

5. Average Hammer Price: The average hammer price of 114.38 euros suggests that, in general, coins of this type tend to sell for above their starting price.

Based on these factors, an estimated maximum purchase price could be in the range of 120 to 150 euros, considering that the condition is good and that interest in the coin appears to be solid. However, since the highest hammer price in the past has been 295 euros, it is possible that in a competitive auction the price could exceed 150 euros, especially if there are several interested bidders.

Therefore, a reasonable maximum purchase price could be 150 euros, but be prepared for a potentially higher bid if demand is strong.

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

1. Starting price: 90 euros.
2. Average hammer price in the past: 160 euros.
3. Condition of the coin: 75 (MBC), which is quite a good condition.
4. Auction history: The coin has been auctioned once before and sold for 160 euros.

Given that the average hammer price in the past was 160 euros and considering that the condition is the same (75), it is reasonable to assume that the hammer price could be in a similar range.

Additionally, since there is an auction scheduled in the coming days and the coin has a history of successful sales, this could increase interest and competition among bidders.

Taking all these factors into account, an estimated maximum purchase price could be around 160-180 euros, as this reflects the previous hammer price and allows for a small margin for competition in the auction.

Therefore, an estimated maximum purchase price would be 180 euros.

Given that the coin has a condition of 70 and considering the history of final bid prices, we can make an estimation. The trend shows that, despite a starting price of 90 euros, the final bid price is usually significantly higher.

Based on the average final bid price of 120 euros and the fact that the coin has performed well in previous auctions, an estimated maximum purchase price could be around 120-130 euros, considering that the starting price is 90 euros and that the condition is acceptable.

Therefore, an estimated maximum purchase price could be 130 euros.
