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

2. Auction History:
- The average hammer price in previous auctions is 69.96 euros.
- The coin has been auctioned 16 times, of which it has sold 10 times, indicating a reasonable sell-through rate.
- Previous hammer prices for coins with similar conditions (75) have varied, but there are examples of hammer prices around 66.83 euros and 163.76 euros for a condition of 75.

3. Starting Price: The starting price is 25 euros, which is quite low compared to the average hammer price.

4. Price Trends: Given that the average starting price is 61.15 euros, and considering that the condition of the coin is 75, it is reasonable to think that the hammer price could be in a range above the starting price.

Based on these factors, an estimated maximum purchase price could be positioned between the average hammer price and a bit more, given that the condition is good.

Estimated Maximum Purchase Price:

We could estimate a maximum purchase price around 80-90 euros. This is based on the auction 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. Coin Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Current Listing Price and Previous Prices: The current listing price is 600 euros. In the past, we have seen auction prices that varied significantly, but there are examples of similar coins that have sold for significantly higher prices, especially those with a condition rating of 90 or above.

3. Previous Auction Prices: Looking at previous auction prices, there are examples of coins with similar conditions that have sold for prices ranging from 100 to over 1000 euros, depending on the condition and demand at the time of the auction.

4. Sales Trends: The coin has been auctioned 39 times, of which 30 have been successful sales. This suggests that there is consistent interest in this coin, which may increase its value.

5. Average Auction Price: The average auction price for similar coins is 229.86 euros, indicating that the current listing price of 600 euros is quite high compared to the average, but it may be justified by the condition and demand.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 800 to 1000 euros. This range considers the good condition of the coin, the historical interest in it, and the potential for the auction price to exceed the current listing price. However, the final price will depend on the competition in the auction and the willingness of other bidders to pay.

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

1. Current Condition: The coin has a condition of 75 (MBC), which indicates that it is in fairly good shape, but not of the highest quality (FDC).

2. Auction History:
- The average starting price of similar coins is 276.3 euros, and the average hammer price is 431.6 euros.
- In the past, coins with the same condition (75) have been auctioned at prices that varied significantly, from 32 euros to 1750 euros. However, the most relevant prices are those that are close to the current condition.

3. Previous Hammer Prices:
- In previous auctions, coins with a condition of 75 have reached hammer prices of up to 1750 euros, but there are also examples of lower hammer prices, such as 210 euros and 180 euros.

4. Current Starting Price: The starting price is 60 euros, which is relatively low compared to the average starting price of 276.3 euros.

5. Recent Trends: In the most recent auction, a coin with a condition of 30 sold for 180 euros, suggesting that there is interest in quality coins, even though the condition is lower.

### Estimation of Maximum Purchase Price
Given that the condition of the coin is 75 and considering the history of hammer prices, a reasonable maximum purchase price could be in the range of 300 to 500 euros. This is based on the average hammer price and the fact that the coin has a low starting price, which could attract more bidders.

Therefore, an estimated maximum purchase price could be approximately 450 euros. This allows for a margin for competition in the auction, given the potential interest in coins of good condition.

To estimate a maximum purchase price for the coin with a grade of 80 (MBC+), we can analyze historical data from previous auctions of coins with the same grade and hammer prices.

1. Historical Auction Data:
- The grade of 80 (MBC+) has had hammer prices that vary significantly. For example, in previous auctions, hammer prices for coins with similar grades have ranged from 170 to 700 euros, depending on demand and other factors.

2. Average Hammer Price:
- The average hammer price for coins of this reference is approximately 406.31 euros. This suggests that, in general, buyers are willing to pay around this amount.

3. Price Trends:
- Observing the trends, it seems that coins with a grade of 80 (MBC+) tend to reach hammer prices that can be slightly higher than the average starting price, especially if there is interest in the auction.

4. Additional Considerations:
- Given that the starting price is 250 euros and the average hammer price is 406.31 euros, a reasonable maximum purchase price could be slightly higher than the average hammer price, considering the grade and demand.

Estimated Maximum Purchase Price:
Taking all these factors into account, an estimated maximum purchase price for the coin with a grade of 80 (MBC+) could be around 450-500 euros. This allows for some competition in the auction and reflects the price trend observed in the past.

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 an acceptable state, but not among the best qualities.

2. Starting Price: The starting price is 2000 euros, which is a good starting point.

3. Auction History:
- The average hammer price for similar coins in the past has been 2833.74 euros.
- It has been auctioned 62 times, of which 45 have been sold, indicating good interest in the coin.
- In previous auctions, hammer prices have varied significantly, with some reaching very high figures (for example, 18263.26 euros in 2011 for a coin with a condition of 90).

4. Price Trends:
- The average hammer price for coins of similar condition (75) has been lower than the overall average, but still, there have been auctions where prices exceeded 2000 euros.

5. Comparison with Previous Prices:
- In previous auctions, coins with a condition of 75 have had hammer prices ranging between 1300 and 3700 euros, depending on demand and other factors.

Based on this data, an estimated maximum purchase price for this coin could be in the range of 3000 to 3500 euros, considering that interest in the coin is high and the average hammer price is 2833.74 euros. This allows for some competition in the auction, while also remaining within a reasonable range given the price history.

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-), indicating that it is in relatively good shape, but not among the best qualities.

2. Auction History:
- The average hammer price in previous auctions is 72.54 euros.
- The average starting price is 59.95 euros.
- In the past, hammer prices have varied significantly, ranging from 20 euros to 200 euros, depending on the condition and demand at the time of the auction.

3. Recent Trends:
- In the most recent auctions, hammer prices have been in a range of 45 to 65 euros for similar conditions (75-85).
- The last auction with a hammer price of 60 euros for a condition of 85 suggests that the market is willing to pay more for coins in better condition.

4. Starting Price: The starting price is 35 euros, indicating that the seller expects a lower price initially, but this does not necessarily reflect the true value of the coin.

Based on these factors, an estimated maximum purchase price for the coin, considering its condition and price history, could be between 70 and 90 euros. This is because, although the condition is not the highest, the interest in VF- quality coins may lead to a hammer price that approaches the higher levels observed in the past.

Therefore, a reasonable estimated maximum purchase price could be 80 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 (MBC+), indicating that it is in quite good shape. This is important because coins in better condition tend to reach higher prices.

2. Auction History:
- The average hammer price for this coin in the past has been 1229.43 euros.
- In previous auctions, hammer prices have varied, but there are examples of hammer prices exceeding 1600 euros (such as in 2016).

3. Starting Price: The current starting price is 700 euros, which is relatively low compared to the average hammer price.

4. Sales Trends: Out of the 10 times it has been auctioned, it has sold 7 times, indicating good demand.

5. Previous Auction Prices:
- In 2020, it was auctioned with a starting price of 700 euros and an estimated price of 900 euros, but it did not sell.
- In 2018, with a starting price of 400 euros, it sold for 440 euros, showing that interest may be increasing.

Given all this, an estimated maximum purchase price could be positioned in a range between the average hammer price and the highest estimated price from previous auctions.

Estimation: Considering the average hammer price of 1229.43 euros and the price history, a reasonable maximum purchase price could be approximately 1300 to 1500 euros. This reflects interest in the coin and its condition, as well as the price trends 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 of 75 (MS), which is a medium level. This suggests that its value will not reach the highest prices seen in coins of better condition.

2. Auction History:
- The average hammer price for similar coins in condition 75 has been approximately 1,000 euros in previous auctions.
- In past auctions, hammer prices for coins with condition 75 have varied, with a maximum price of 1,775.51 euros in 2016.

3. Starting Price and Average Starting Price:
- The current starting price is 250 euros, which is relatively low compared to the average starting price of 487.2 euros. This suggests that there is potential for an increase in the hammer price.

4. Recent Trends: In the most recent auction, the coin sold for 550 euros, indicating that there is interest in the coin, but also that the market may be a bit more cautious.

5. Comparison with Previous Prices:
- The 2022 auction with condition 90 had a starting price of 713.33 euros, indicating that condition significantly affects the price.

Taking all these factors into account, an estimated maximum purchase price for the coin in condition 75 could be in the range of 800 to 1,000 euros. This is based on the historical hammer prices for coins of similar condition and the current interest in the coin.

Therefore, a reasonable maximum purchase price could be 1,000 euros.
