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 75 (MBC), indicating that it is in quite good shape.

2. Previous Prices: By looking at previous auction prices for coins with a similar condition (75-80), we can see that auction prices have varied. For example:
- In past auctions, coins with a condition of 75 have reached hammer prices of 50, 60, 70, 80, and even 190 euros in exceptional cases.
- The average hammer price for coins with a condition of 75 seems to be in the range of 60-80 euros.

3. Average Hammer Price: The average hammer price for this coin is 84.07 euros, which is also a good indicator of market value.

4. Starting Price: The starting price is 35 euros, suggesting that there is considerable room for the hammer price to be higher.

5. Sales Trends: The coin has been sold in 43 out of 53 auctions, indicating good demand.

Based on these factors, an estimated maximum purchase price could be in the range of 80 to 100 euros, considering that the condition is good and the average hammer price is 84.07 euros. However, to be more conservative and avoid overpaying, a reasonable maximum purchase price could be 90 euros.

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

1. Current Condition: The coin has a condition of 85 (ebc-), which indicates that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price of similar coins in the past is 68.73 euros.
- In previous auctions, we have seen hammer prices that varied significantly, but there are examples of sales in the range of 75 to 160 euros for coins with similar conditions.

3. Starting Price and Average Starting Price:
- The current starting price is 40 euros, which is relatively low compared to the average hammer price.
- The average starting price of 49.79 euros also suggests that the current starting price is attractive.

4. Sales Trends: Since this coin has sold every time it has been auctioned (15 out of 15), this indicates a consistent demand.

5. Comparison with Previous Prices:
- In the most recent auction (2023-03-16), a coin with a condition of 95 sold for 150 euros. This suggests that a coin with a condition of 85 could reach a lower, yet still significant, price.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 100 to 130 euros. This is based on the condition, the hammer price history, and the demand observed in previous auctions.

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

1. Coin Condition: The coin has a condition rating of 70 (MS-), indicating that it is in acceptable condition, but not among the highest quality. This can influence the price, as coins in better condition tend to fetch higher prices.

2. Auction History: The coin has been auctioned 105 times, of which it has sold 96 times. This indicates good demand and consistent interest in the coin. The average hammer price in the past has been 114.28 euros, providing a reference point.

3. Recent Starting and Hammer Prices: In the most recent auctions, starting prices have varied, but the average starting price is 65.03 euros. However, the hammer price can be significantly higher, as seen in previous auctions.

4. Price Trends: By observing the hammer prices from previous auctions, it can be noted that at times the coin has reached hammer prices exceeding 100 euros, especially in higher condition grades.

Given all this, an estimated maximum purchase price for this coin, considering its condition and price history, could be around 120-140 euros. This is based on the average hammer price and the price trend in previous auctions for coins of similar condition.
