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 in previous auctions is 104.02 euros, suggesting that, in general, coins of this reference tend to sell above their starting price.
- In the most recent auction (2022), a coin with a similar condition (85) sold for 68 euros, which may be an indicator of its current market value.

3. Starting Price: The starting price is 70 euros, which is a reasonable starting point for the auction.

4. Sales Trends: Out of the 10 times it has been auctioned, it has sold 4 times, indicating a moderate interest in this coin.

5. Comparison with Previous Prices: In previous auctions, hammer prices have varied, but there are examples of sales above 100 euros, especially for coins in better condition.

Taking all these factors into account, an estimated maximum purchase price could be around 100-120 euros. This is based on the hammer price history and the current condition of the coin. However, it is important to consider that the final price may be affected by competition in the auction and demand at the time of sale.

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 75 (MBC), indicating 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 in previous auctions is 96.03 euros.
- The average starting price is 70.2 euros.
- In past auctions, we have seen hammer prices that varied significantly, ranging from 42 euros to 422.6 euros, depending on the condition and demand at that time.

3. Recent Trends:
- In the most recent auctions, the starting price has been 40 euros, with an estimated price of 60 euros. This suggests that interest in the coin remains, but there may be some downward pressure on the starting price.

4. Comparison with Previous Prices:
- In previous auctions with similar condition (75), hammer prices have ranged between 60 and 110 euros.

Taking all these factors into account, an estimated maximum purchase price could be around 100 euros. This price reflects a balance between the coin's condition, price history, and current market trend. However, it is important to stay alert to the auction dynamics and competition, as this can influence the final price.

To estimate a maximum purchase price for the coin that is going to be auctioned, we can consider several factors:

1. Condition of the coin: The coin in question has a condition rating of 80 (MBC+), which indicates that it is in relatively good shape. This is important because coins in better condition tend to fetch higher prices.

2. Previous auction prices: By looking at the hammer prices of coins with similar conditions, we can see that:
- In the past, coins with a condition rating of 80 have reached hammer prices of up to 280 euros (in 2011).
- The average hammer price for coins of similar condition seems to be around 85.8 euros.

3. Starting price and average starting price: The current starting price is 40 euros, and the average starting price in the past has been 68.32 euros. This suggests that the current starting price is relatively low compared to the historical average.

4. Sales trends: The coin has been auctioned 142 times, of which it has sold 78 times. This indicates that there is considerable interest in this coin, which may influence the hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 120 to 200 euros, considering that the condition is good and there are precedents for higher hammer prices in the past. However, given the starting price of 40 euros, it is likely that the hammer price will not significantly exceed 200 euros unless there is intense competition among bidders.

Therefore, a reasonable estimated maximum purchase price could be 150 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 80 (MBC+), which indicates that it is in quite good shape. This generally increases its value compared to coins with lower conditions.

2. Auction History:
- In 2013, a coin with a condition of 90 was auctioned with a starting price of 146.49 euros, although the final price is not known.
- In 2021, a coin with a condition of 75 had an unspecified starting price but sold for 52.64 euros.

3. Starting Prices and Average Prices:
- The current starting price is 50 euros, and the average starting price in the past has been 98.25 euros, with an average final price of 52.64 euros.

4. Demand and Supply: The coin has been auctioned 2 times in the past, of which it has sold 1 time. This suggests that there is moderate interest in the coin.

Given that the current condition of the coin is better than that of the 2021 auction and is close to that of 2013, we can infer that its value could be closer to the starting price of 146.49 euros for the coin with a condition of 90, although it will not reach that price due to the difference in condition.

Taking all these factors into account, an estimated maximum purchase price could be between 70 and 90 euros, considering that the condition is good and there is moderate interest in the coin. A price of 80 euros could be a reasonable starting point for an offer.

To estimate a maximum purchase price for the coin that is going to be auctioned, we will consider several factors:

1. Condition of the coin: The coin in question has a condition of 80 (MS+), which indicates that it is in relatively good shape, but not among the best qualities.

4. Starting price: The starting price of 50 euros is a good starting point, but given that the average hammer price is significantly higher, it is reasonable to expect that the final hammer price will exceed the starting price.

5. Recent trends: In recent auctions, hammer prices have shown a trend of being higher, as seen in the October 2022 auction, where a similar coin sold for 180 euros.

Taking all these factors into account, an estimated maximum purchase price for the coin in question could be between 80 and 120 euros, considering that the condition is good and that interest in coins of this reference may lead to a higher hammer price.

Therefore, a reasonable estimated maximum purchase price could be 100 euros.
