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 relatively good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Starting Price and Average Hammer Price: The starting price is 70 euros, and the average hammer price in previous auctions is 104.74 euros. This suggests that, on average, similar coins have reached prices above the starting price.

3. Sales History: The coin has been auctioned 44 times, of which 39 have resulted in sales. This indicates good demand and consistent interest in the coin.

4. Previous Prices: Looking at previous hammer prices for coins with similar conditions, we can see that they have reached hammer prices that vary, but some have reached 150 euros or more in similar conditions.

5. Recent Trends: In the most recent auctions, the hammer prices have shown a range that suggests the coin could reach a hammer price above average, especially considering the growing interest in coins of good condition.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 120 to 150 euros. This is based on the condition, price history, and recent sales trends.

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

2. Previous Prices: By looking at previous auction prices for coins with similar conditions (70 and 75), we can see that:
- In 2020, a coin with a condition of 70 was auctioned for 43 euros.
- In 2018, another coin with a condition of 70 was auctioned for 50 euros.
- In 2022, a coin with a condition of 70 was auctioned for 75 euros.

3. Price Trends: The average auction price for similar coins is 175.17 euros, but this includes coins in better condition. Given that the condition of this coin is 70, it is reasonable to expect that its auction price will be below this average.

4. Starting Price: The starting price is 25 euros, indicating that the auction house expects moderate interest in the coin.

5. Sales History: The coin has been auctioned 47 times, of which 45 have sold. This suggests that there is an active market for this coin.

Based on these factors, an estimated maximum purchase price for this coin could be between 50 and 80 euros, considering that the condition is a limiting factor and that previous auction prices for coins of similar condition have been in that range.

Therefore, a reasonable maximum purchase price could be 70 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 30 (BC+). This is relatively low compared to other coins that have been auctioned in the past, where many have higher conditions (70, 80, 90, etc.).

2. Auction History:
- The average hammer price for similar coins is 541.12 euros.
- The average starting price is 464.18 euros.
- In the past, coins with similar conditions have sold for prices that varied considerably, but generally, coins in better condition have reached much higher prices.

3. Previous Prices:
- Previous auctions of coins with conditions between 25 and 30 have had hammer prices ranging from 15 to 320 euros, depending on demand and the rarity of the coin.
- The last auction of a coin with a similar condition (30) had a hammer price of 56 euros.

4. Market Trends: Given that the coin has a starting price of 12 euros, it is likely that collector interest is not very high, which could limit the hammer price.

Based on these factors, an estimated maximum purchase price for this coin could be between 50 and 80 euros, considering that it is a coin with a low condition and that market interest may not be very high. However, if there is particular interest in this specific coin, the price could be higher, but it is unlikely to exceed 100 euros in this condition.

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 relatively good shape. This suggests that its value should be above that of coins with lower conditions.

2. Previous Auction Prices: By observing the hammer prices of coins with similar conditions (around 80), we can see that the hammer prices have varied. For example:
- In 2018, a coin with a condition of 80 was auctioned for a hammer price of 200 euros.
- In 2022, another coin with a condition of 80 was sold for 95 euros.

3. Average Hammer Price: The average hammer price for this coin is 233.42 euros, indicating that, in general, coins of this reference tend to reach higher prices.

4. Starting Price and Previous Hammer Prices: The current starting price is 40 euros, which is significantly lower than previous hammer prices. This could indicate a good buying opportunity.

5. Auction Trends: Given that there have been 58 previous auctions and 52 sales, demand appears to be high, which may influence the hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 200 to 300 euros, considering that the average hammer price is 233.42 euros and there are examples of previous sales exceeding 200 euros.

Therefore, a reasonable maximum purchase price could be 250 euros.

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 hammer price for this coin in the past has been 187.06 euros.
- The condition of coins auctioned in the past has varied, but there are examples of coins with higher conditions that have reached significantly higher prices (for example, a coin with a condition of 95 was sold for 875 euros).

3. Recent Starting and Hammer Prices:
- The current starting price is 15 euros, which is relatively low.
- In previous auctions, hammer prices have varied, but there are examples of coins with similar conditions that have sold for prices ranging between 15 and 30 euros.

4. Market Trends: Since the coin has been auctioned 40 times and has had a sell-through rate of 97.5%, this suggests that there is consistent interest in this coin, which may influence its price.

Based on these factors, an estimated maximum purchase price for this coin could be between 30 and 50 euros. This takes into account its current condition and the auction price history, as well as the interest in the coin. However, since the starting price is 15 euros, it may be possible to acquire it for a lower price if there is not much competition in the auction.
