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 relatively good shape. This can positively influence its value.

2. Auction History:
- It has been auctioned 11 times, of which it has sold 10 times. This suggests there is consistent interest in the coin.
- The average hammer price in previous auctions is 68.54 euros, which can serve as a good indicator of market value.

3. Starting and Hammer Prices:
- The current starting price is 50 euros, which is lower than the average hammer price from previous auctions. This could indicate a good buying opportunity.
- In previous auctions, hammer prices have varied, but there are examples of hammer prices exceeding 100 euros, especially for coins in higher conditions.

4. Price Trends:
- In 2016, a coin with the same condition sold for 101.3 euros, suggesting there is potential to reach higher prices in the future.

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 that interest in the coin appears to be solid. A price of 90 euros could be a reasonable target, as it is in the middle of this range and aligns with previous hammer prices.

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 30 (BC+), indicating that it is not in the best condition. This generally reduces its value compared to coins in better condition.

2. Auction History:
- The average starting price for similar coins is 183.72 euros, and the average hammer price is 229.86 euros.
- In the past, coins of this reference have been auctioned with hammer prices that varied significantly, from low prices (like 20 euros) to much higher prices (like 1153.23 euros in much better condition).

3. Sales Trends: The coin has sold in 30 out of 39 auctions, indicating good demand. However, the fact that there have been 9 auctions where it did not sell suggests that the starting price may be a determining factor.

4. Current Starting Price: The starting price is 30 euros, which is relatively low compared to the average starting price of other similar coins.

Given that the condition of the coin is low and the starting price is 30 euros, an estimated maximum purchase price could be in a range that considers the condition and the price history.

Taking all these factors into account, an estimated maximum purchase price could be around 70-90 euros. This is based on the fact that, although the condition is not high, the interest in the coin and the price history suggest that it could reach a higher price than the starting price, but not so much as to exceed the hammer prices of coins in better condition.

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 for this coin in the past has been 132.58 euros.
- Hammer prices of up to 438.33 euros have been recorded for coins in superior conditions (107).
- In similar conditions (75 and 80), hammer prices have ranged between 55 and 140 euros.

3. Starting Price: The current starting price is 35 euros, indicating that the auctioneer expects moderate interest in the coin.

4. Recent Trends: In the most recent auctions, hammer prices have been in the range of 70 to 110 euros for conditions of 75 and 80.

Based on this data, an estimated maximum purchase price for the coin with a condition of 70 could be in the range of 80 to 120 euros. This is because, although the condition is not the highest, there is a price history suggesting it could reach a reasonable price at auction.

Therefore, an estimated maximum purchase price could be 100 euros. This allows for some competition in the auction, considering that the average hammer price is 132.58 euros, but adjusted for the current condition.

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

2. Auction History:
- The average hammer price for this coin in the past has been 132.58 euros.
- Hammer prices have varied significantly, ranging from 30 euros to 550.03 euros in previous auctions, depending on the condition and other factors.

3. Prices of Similar Condition:
- In previous auctions, coins with a condition rating of 75 have reached hammer prices of 160.56 euros (2013), 114.54 euros (2014), and 249.14 euros (2015). This suggests that the price range for coins in similar conditions can be quite broad.

4. Starting Price: The current starting price is 30 euros, indicating that the auctioneer expects interest in the coin, but the starting price is significantly lower than previous hammer prices.

5. Recent Trends: In the most recent auctions, hammer prices have been in the range of 70 to 110 euros for similar conditions.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 150 to 200 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate. However, since the market can be volatile, it is advisable to keep an eye on the auction and adjust the bid accordingly.

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 70 (VF-). This indicates that it is in an acceptable state, but not of high quality. Coins in better condition (for example, 90 or 110) tend to reach significantly higher prices.

2. Historical Prices: By looking at previous auction prices for coins of similar condition, we can see that there is a great variability. For example:
- In 2011, a coin with a condition of 90 was auctioned for 2665.69 euros.
- In 2014, a coin with a condition of 75 sold for 420 euros.
- In 2019, a coin with a condition of 95 sold for 6000 euros.

3. Average Auction Price: The average auction price for this coin is 597.72 euros, suggesting that, in general, coins of this reference tend to sell for relatively high prices.

4. Starting Price: The current starting price is 130 euros, which is quite low compared to previous auction prices.

5. Sales Trends: The coin has been auctioned 34 times, of which 30 have resulted in sales. This indicates good demand in the market.

Given all this, an estimated maximum purchase price could be set in a range that considers the current condition and previous auction prices.

Estimation: Based on the condition of 70 and previous auction prices, a reasonable maximum purchase price could be between 300 and 500 euros. This is based on the trend that coins in similar conditions have reached auction prices in that range, although the exact price may vary depending on demand in the specific auction.

Therefore, an estimated maximum purchase price could be approximately 400 euros.

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 75 (MBC), indicating average quality. This can influence the price, as coins in better condition tend to fetch higher prices.

2. Starting Price and Previous Prices: The current starting price is 70 euros. In previous auctions, the average hammer price for coins of similar condition has varied, with some prices reaching up to 732.53 euros for coins in better condition (90) and others in similar conditions (75) selling for prices ranging between 95 and 180 euros.

3. Price Trends: The average hammer price for coins in condition 75 has been approximately 231.8 euros. This suggests that, although the starting price is low, the potential selling price could be considerably higher.

4. Historical Data: By looking at the hammer prices of similar coins in the past, it can be seen that there is significant variability. However, the highest recorded price for a coin in condition 75 was 800 euros, indicating that there is a market willing to pay high prices for quality coins.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 200 to 300 euros. This is based on the average hammer price and the price trend for coins of similar condition. However, it is important to note that the final price may vary depending on demand at the auction and other market factors.

1. Current Condition: The coin has a condition of 30 (BC+), which is relatively low compared to other coins that have been auctioned in the past. This can significantly affect its value.

2. Previous Auction Prices: By observing the auction prices of similar coins in higher condition (for example, 75 or 90), prices have varied considerably, reaching figures of up to 4000 euros in some cases. However, for coins in lower conditions, the auction prices are much lower.

3. Average Auction Price: The average auction price for this coin is 406.31 euros, indicating that, in general, coins of this reference tend to sell at relatively high prices, but this is based on more favorable condition.

4. Starting Price: The starting price is 50 euros, suggesting that the auction house expects moderate interest in the coin.

5. Recent Trends: Recent auctions have shown increasing interest in coins, but they have also reflected variability in prices depending on condition.

Given that the condition of this coin is 30 (BC+), and considering previous auction prices and the average price, an estimated maximum purchase price could be in the range of 150 to 250 euros. This is based on the idea that, although the coin has a potential higher value in better condition, its current state will limit its appeal and, therefore, its auction price.

Maximum Purchase Estimate: 250 euros.
