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 similar coins has been 115.67 euros.
- In previous auctions, coins with similar conditions (around 70) have had hammer prices that varied, but some examples are:
- 55 euros (condition 75)
- 52 euros (condition 80)
- 90 euros (condition 80)
- 130 euros (condition 80)
- The trend shows that coins with conditions from 70 to 80 can reach hammer prices between 50 and 130 euros.

3. Starting Price: The starting price is 18 euros, indicating that the seller expects a lower price initially, but this does not necessarily reflect the actual value of the coin.

4. Previous Prices: In previous auctions, the highest hammer price for coins with similar conditions has been 190 euros (condition 95), but this is an exceptional case.

Based on these factors, an estimated maximum purchase price for the coin with a condition of 70 could be in the range of 80 to 120 euros, considering that the average hammer price is 115.67 euros and that the condition is slightly lower than that of coins that have reached higher prices.

Therefore, a reasonable estimated maximum purchase price could be 100 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 75 (MBC), 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 for similar coins in the past is 135.77 euros.
- The coin has been auctioned 14 times, of which it has sold 13 times, indicating good demand.
- Previous hammer prices for coins with similar conditions (70-80) have varied, but there are examples of auctions reaching up to 150 euros.

3. Starting Price and Average Starting Price:
- The current starting price is 25 euros, which is quite low compared to the average starting price of 94.62 euros. This suggests that there is potential for a significant increase in the hammer price.

4. Price Trends:
- In previous auctions, hammer prices have shown a trend of being significantly higher than starting prices, especially for coins in good condition.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 150 to 180 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 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 coin has been auctioned 7 times and has sold on all occasions, suggesting consistent demand.
- The average hammer price in previous auctions is 43 euros, which can serve as a good indicator of market value.

3. Previous Prices:
- Previous hammer prices for coins with similar conditions (80) have been 31 and 30 euros, indicating that the price may vary depending on the condition.
- In the case of the 2014 auction, the hammer price was 130 euros, but this may have been influenced by a higher condition or other market factors at that time.

4. Starting Price and Average Starting Price:
- The current starting price is 18 euros, which is quite low compared to the average hammer price of 43 euros. This suggests that there is potential for the hammer price to be significantly higher.

Based on these factors, an estimated maximum purchase price could be in the range of 50 to 70 euros, considering that the condition is good and that the price history suggests there is demand. However, since the starting price is low, there may be an opportunity for the hammer price to be even higher if there is interest among bidders.

Therefore, a reasonable maximum purchase price could be 65 euros.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, including the current grade, previous auction prices, and trends in past auctions.

1. Current Grade: The coin has a grade of 70 (MBC-), indicating that it is in acceptable condition, but not of the highest quality.

2. Previous Auction Prices:
- In previous auctions, hammer prices have varied considerably. For example:

- The average hammer price for this coin is 73.89 euros, suggesting that, in general, buyers are willing to pay around this price.
- The average starting price is 29 euros, indicating that sellers are starting the auctions at a lower price.

4. Estimation Based on Grade:
- Given that the coin's grade is 70, and considering that in the past it has sold for prices around 35-40 euros in similar conditions, we can estimate that the hammer price could be in a similar range.

5. Maximum Purchase Price:
- Taking all these factors into account, an estimated maximum purchase price could be between 40 and 60 euros, considering that price trends may vary and that the grade is an important factor.

Therefore, an estimated maximum purchase price for this coin could be 50 euros.

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

1. Current starting price: 25 euros.
2. Current condition: 30 (BC+), indicating a low condition.
3. Auction history:
- In 2014, the coin was auctioned with a starting price of 90 euros and sold for 110 euros.

4. Average starting and final prices:
- Average starting price: 63.33 euros.
- Average final price: 77.5 euros.

Given that the current condition is quite low (30), this will negatively affect the estimated price. However, the auction history shows that in better conditions, the coin has reached significantly higher final prices.

Taking all these factors into account, an estimated maximum purchase price could be positioned between the average final price and the highest final price in the past, adjusted for the current condition.

Therefore, a reasonable maximum purchase price could be around 50-60 euros. This reflects a compromise between the price history and the current condition of the coin.

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 25 (BC), which indicates that it is not in the best shape. This generally reduces its value compared to coins in better condition.

2. Auction history:
- The average hammer price in previous auctions for coins with a similar condition (25) has been 45 euros.
- The average starting price has been 32.88 euros, indicating that starting prices are usually lower than hammer prices.

3. Price trends:
- In previous auctions, hammer prices have varied, but the range has been between 20 and 100 euros, depending on condition and other factors.

4. Current starting price: The starting price is 18 euros, which is relatively low and may attract more bidders.

Given that the coin's condition is 25 and considering the hammer price history, an estimated maximum purchase price could be around 45 euros, which is the average hammer price for coins in similar condition. However, since the starting price is low, some bidders may be willing to pay a bit more.

Therefore, a reasonable estimated maximum purchase price could be 45 to 50 euros.

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

1. Coin Condition: The coin has a condition rating of 70 (MS-), which indicates that it is in acceptable condition but not of high quality. This generally affects the price, as coins in better condition tend to fetch higher prices.

Taking all these factors into account, an estimated maximum purchase price for this coin could be between 300 and 400 euros, considering that the condition and auction history suggest it could reach a higher price, but it is also important to note that the starting price is 225 euros, which could attract more bidders and potentially raise the hammer price.

Therefore, a reasonable maximum purchase price could be 350 euros.
