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

1. Condition: The coin has a condition rating of 75 (MBC), indicating that it is in quite good shape. This generally increases its value compared to coins in lower condition.

2. Auction History:
- It has been auctioned 5 times in the past, of which it has sold 4 times. This suggests that there is consistent interest in the coin.
- The average hammer price in previous auctions is 97.5 euros, indicating that, in general, buyers are willing to pay close to this price for similar coins.

3. Previous Starting and Hammer Prices:
- In previous auctions, starting prices have varied, but the highest hammer price was 125 euros in 2014, which sets a precedent for the value of the coin in good condition.
- The current starting price is 40 euros, which is relatively low compared to the average hammer price.

4. Market Trends: Since the average hammer price is significantly higher than the current starting price, this suggests that there is potential for the coin to sell at a higher price.

Taking all these factors into account, an estimated maximum purchase price could be around 100-120 euros, considering that the condition is good and that interest in the coin appears to be solid. This also aligns with the average hammer price in previous auctions.

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

1. Condition: The coin to be auctioned has a condition of 70 (MBC-). This is slightly lower than previous coins that have sold, which have a condition of 80. This could influence the price, as lower condition generally means a lower price.

2. Previous Prices: Previous auction prices for coins with a condition of 80 have been in a range of approximately 200 to 220 euros. Since the condition of the current coin is lower, it is reasonable to expect that the auction price will be somewhat lower.

3. Starting Price and Average Hammer Price: The starting price is 200 euros, and the average hammer price in the past has been 210.67 euros. This suggests that the hammer price could be in a similar range.

4. Auction Trends: Given that this coin has a history of successful sales (sold 6 times out of 6 auctions), this indicates a consistent interest in the coin, which could help maintain the price.

Taking all these factors into account, an estimated maximum purchase price could be around 200-210 euros, considering that the condition is a limiting factor. However, given the interest in the coin and the price history, a reasonable maximum purchase price could be approximately 210 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 75 (MS), indicating that it is in fairly good shape, but not the best possible condition.

2. Historical Prices: Looking at previous auction prices for coins with a similar condition (75), we can see that they have varied. For example:
- In 2020, a coin with a condition of 75 was auctioned for 400 euros.
- In other auctions, hammer prices have ranged from 130 to 495 euros for similar conditions.

3. Average Hammer Price: The average hammer price for this coin is 353.51 euros, which gives us a good reference for what buyers are willing to pay.

4. Starting Price: The starting price is 175 euros, which is relatively low compared to previous hammer prices.

5. Sales Trends: The coin has been auctioned 81 times, of which 72 have been sold, indicating good demand.

Based on these factors, an estimated maximum purchase price could be in the range of 350 to 450 euros, considering that the average hammer price is 353.51 euros and that there are examples of previous auctions exceeding 400 euros.

Therefore, a reasonable maximum purchase price could be 450 euros.

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

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

2. Previous Auction Prices: By looking at previous auction prices for coins with a similar condition (95), we find that they have reached auction prices of up to 320 euros in recent sales. For example:
- In 2019, a coin with a condition of 95 was sold for 320 euros.
- In 2020, another coin with the same condition was sold for 180 euros.

3. Average Auction Price: The average auction price for this coin is 128.03 euros, indicating that, in general, coins of this reference tend to sell for above this price.

4. Starting Price: The current starting price is 125 euros, suggesting that the seller has expectations for the coin to sell for a reasonable price.

5. Auction Trends: Given that it has been auctioned 79 times and sold 68 times, this indicates good demand for this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 250 to 320 euros, considering that the condition is high and there are precedents for sales in that range. However, since the starting price is 125 euros, it is likely that buyers will be willing to bid more, especially if there is interest in the coin.

Therefore, an estimated maximum purchase price could be approximately 300 euros.
