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

1. Current Condition: The coin has a condition rating 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. Auction History:
- The average hammer price for this coin in the past has been 112.52 euros.
- Previous auctions with similar conditions (90 and 85) have had hammer prices that varied, but some have reached significant prices, such as 315.39 euros in an auction with a condition of 90.

3. Starting Price and Average Starting Price:
- The current starting price is 75 euros, and the average starting price in the past has been 70.57 euros. This suggests that the current starting price is reasonable and could attract bidders.

4. Sales Trends: The coin has been sold in 23 out of 34 auctions, indicating a consistent interest in the coin.

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 the auction price history suggests buyers are willing to pay more for coins in similar conditions.

Therefore, an estimated maximum purchase price could be 135 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 (MBC), indicating that it is in an acceptable state, but not of the highest quality.

2. Auction History:
- The average hammer price in previous auctions is 190.03 euros, suggesting that, in general, coins of this reference tend to reach higher prices.
- However, it should also be noted that there have been auctions where the coin did not sell, which may indicate that interest can vary.

3. Previous Auction Prices:
- In previous auctions, hammer prices have varied significantly, ranging from 35.89 euros to 375.32 euros, depending on the condition and other factors.
- The last auction where the coin was sold with a condition of 75 had a hammer price of 35 euros, which is an indicator that interest may not be very high in this state.

4. Current Starting Price: The starting price is 50 euros, which is relatively low compared to the average hammer price.

5. Sales Trends: The coin has sold 50% of the times it has been auctioned, indicating moderate interest.

Based on these factors, an estimated maximum purchase price could be set in a range that considers both the starting price and the hammer price history. Given that the condition is 75 and considering the average hammer price, a reasonable maximum price could be:

Estimated maximum purchase price: 100 - 120 euros.

This range takes into account the condition and price history, allowing for some margin for competition in the auction.

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 70 (VF-), indicating that it is in relatively good shape. This suggests that its value should be above that of coins in worse conditions.

2. Previous auction prices:
- In 2018, the coin was auctioned with a starting price of 75 euros and sold for 85 euros.
- In 2015, the starting price was 138.68 euros, although the final price is not indicated.
- In 2019 and 2020, the starting prices were 65 and 50 euros, respectively, but the outcomes of those auctions are unknown.

3. Average starting and final prices: The average starting price is 73.74 euros, and the average final price is 85 euros. This indicates that, in general, coins of this reference tend to sell within a similar range.

4. Current auction situation: The current starting price is 40 euros, which is significantly lower than previous starting prices. This could attract more bidders, potentially increasing the final price.

Given that the condition is good and considering previous final prices, an estimated maximum purchase price could be in a range between the average final price (85 euros) and the highest recorded final price (85 euros in 2018).

Therefore, an estimated maximum purchase price could be approximately 85-90 euros. This takes into account the possibility that the auction may attract interest due to the low starting price and the good condition of the coin.

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 70 (VF-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Auction History:
- The average hammer price in previous auctions is 202.85 euros, indicating that, in general, coins of this reference tend to sell for significantly higher prices than the starting price.
- The last auction with a notable hammer price was in 2015, where a coin with a condition of 90 sold for 508.48 euros. This suggests that coins in better condition can reach very high prices.

3. Starting Price and Average Starting Price:
- The current starting price is 40 euros, which is quite low compared to the average hammer price. This could indicate a good buying opportunity.

4. Sales Trends: Of the 12 times it has been auctioned, it has sold on 9 occasions, showing consistent interest in this coin.

5. Estimation Based on Condition: Given that the condition of this coin is 70, we can estimate that its hammer price could be in a lower range than coins in better condition (like the one with a condition of 90 that sold for over 500 euros). However, given the price history, a hammer price in the range of 200-300 euros could be reasonable.

Taking all these factors into account, an estimated maximum purchase price for this coin could be between 200 and 250 euros. This would provide a good buying opportunity, considering the price history and the current condition of the coin.

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 75 (MBC), indicating that it is in fairly good shape, but not the best possible condition.

2. Auction History:
- The coin has been auctioned 6 times and has sold on all occasions, indicating a consistent interest in the coin.
- The average hammer price in previous auctions is 57.61 euros, which can serve as a reference for the expected selling price.

3. Previous Prices:
- In 2013, the coin sold for 82 euros at auction, which is a notably high price compared to other hammer prices.
- In 2014, it sold for 66.04 euros at auction with a condition rating of 90, suggesting that better condition can increase the price.

4. Starting Price: The current starting price is 50 euros, which is a good starting point.

Given that the coin's condition is 75 and considering the price history, an estimated maximum purchase price could be in a range between the average hammer price (57.61 euros) and the highest recorded price (82 euros).

Taking all these factors into account, a reasonable estimated maximum purchase price could be around 70-75 euros. This reflects interest in the coin, its condition, and the price history in previous auctions.

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

1. Starting Price: 40 euros. This is the initial price of the auction.
2. Auction History: The coin has been auctioned 4 times in the past, of which it has sold 2 times. This indicates a moderate interest in the coin.
3. Average Starting and Hammer Price: The average starting price is 83.75 euros and the average hammer price is 90 euros. This suggests that, in general, coins of this reference tend to sell for higher prices than the current starting price.
4. Condition: The coin has a condition rating of 75 (VF), which is a positive factor, as coins in better condition usually fetch higher prices.
5. Previous Prices: In previous auctions, the hammer prices have been 90 euros and 90 euros, with a starting price of 120 euros in one earlier auction.

Given that the average hammer price is 90 euros and considering the condition of the coin, an estimated maximum purchase price could be set in a range between the average hammer price and a bit higher, given that the condition is good.

Therefore, an estimated maximum purchase price could be around 90 to 100 euros. This reflects the interest in the coin and its condition, as well as the price history in previous auctions.

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 (VF), indicating that it is in acceptable shape, but not of the highest quality.

2. Auction History:
- The average hammer price in previous auctions is 82.61 euros.
- The average starting price is 68.39 euros.
- In past auctions, we have seen hammer prices that varied significantly, ranging from 3 euros to 200 euros, depending on the condition and demand at that time.

3. Recent Auction Prices:
- In the most recent auction, the hammer price was 55 euros for a coin with a condition of 80.
- In another recent auction, the hammer price was 70 euros for a coin with a condition of 90.

4. Price Trends:
- The general trend seems to be that coins in a condition similar to the current one (75) have had hammer prices ranging between 50 and 80 euros in recent auctions.

Based on this data, an estimated maximum purchase price for the coin in condition 75 could be in the range of 70 to 90 euros, considering that the starting price is 40 euros and that interest in the coin may influence the final price.

Therefore, a reasonable estimated maximum purchase price could be 80 euros.
