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

1. Starting price: 70 euros.
2. Current grade: 70 (MBC-).
3. Auction history: The coin has been auctioned 12 times and has sold in all of them, indicating good demand.
4. Average hammer price: 119.17 euros, suggesting that, on average, coins of this reference sell for a price higher than the starting price.
5. Previous prices:
- In recent auctions, hammer prices have varied, but there are examples where hammer prices have reached up to 270 euros (although with a higher grade).
- The last auction with a grade of 80 had a hammer price of 190 euros.

Given that the grade of the coin in question is 70 (MBC-), which is lower than the grades of some coins that have sold for higher prices, but still an acceptable grade, we can make an estimation.

### Estimation of the maximum purchase price:
- Considering the average hammer price (119.17 euros) and the fact that grade is an important factor, a reasonable maximum purchase price could be in the range of 120 to 150 euros. This is based on the fact that the coin has a history of successful sales and a hammer price that exceeds the starting price.

Therefore, an estimated maximum purchase price could be 150 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 85 (MS+/EF-), indicating that it is in quite good shape. This generally translates to a higher price compared to coins in lower condition.

2. Auction History:
- The average hammer price in previous auctions is 56.38 euros.
- The coin has been auctioned 9 times, of which it has sold 8 times, indicating good demand.
- Previous hammer prices varied, but there are examples of hammer prices reaching up to 55 euros in similar conditions.

3. Starting Price and Average Starting Price:
- The current starting price is 50 euros, which is slightly lower than the average starting price of 53.67 euros. This may indicate that the seller is looking for a quick sale or that there is an expectation that the price will not rise much further.

4. Price Trends:
- In previous auctions, hammer prices have fluctuated, but there is a price pattern suggesting that coins in similar conditions have reached hammer prices ranging from 30 to 55 euros.

Based on these factors, an estimated maximum purchase price could be in the range of 60 to 70 euros. This is because, although the starting price is 50 euros, the good condition and price history suggest that there may be enough interest for the hammer price to exceed the previous average.

Therefore, a reasonable maximum purchase price could be 70 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 70 (VF-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Previous Auction Prices: Looking at the auction prices of coins with a similar condition (70), we see that in the past they have sold for:
- €300 (2020)
- €460 (2019)
- €500 (2023)

The highest auction price for a condition of 70 was €500.

3. Average Auction Price: The average auction price for all auctions of this coin is €886.5, but this includes coins in better conditions.

4. Auction Trends: The coin has been auctioned 18 times, of which 16 have sold. This indicates good demand.

5. Starting Price: The starting price is €300, which suggests that the seller has moderate expectations.

Given that the coin's condition is 70 and considering the previous auction prices, an estimated maximum purchase price could be around €500-600, taking into account that the market can fluctuate and that demand may influence the final price.

Therefore, a reasonable estimated maximum purchase price would be €600.

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

2. Auction History:
- The average hammer price for similar coins is 121.29 euros.
- In previous auctions, coins with similar conditions (75-85) have reached hammer prices that varied, but some examples are:
- 140 euros (2019-10-17) for a coin with a condition of 85.
- 200 euros (2020-10-21) for a coin with a condition of 85.
- 110 euros (2020-04-29) for a coin with an unspecified condition, but which sold above its starting price.

3. Starting Price and Previous Prices:
- The current starting price is 50 euros, which is below the average hammer price of similar coins.
- The average starting price of 61.84 euros also suggests that the current starting price is low.

4. Sales Trends: The coin has been sold in 35 out of 40 auctions, indicating good demand.

Based on these factors, an estimated maximum purchase price could be in the range of 150 to 200 euros, considering that the condition is good and that the auction price history for similar coins supports this estimate.

Therefore, a reasonable maximum purchase price could be 150 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 rating of 30 (BC+), indicating that it is not in the best condition. This will affect its value compared to coins in better condition.

2. Historical Prices: By looking at the auction prices of similar coins in the past, we can see that prices vary significantly depending on the condition. For example, coins with a condition rating of 75 have reached auction prices of up to 600 euros, while coins with a condition rating of 10 have also had auction prices of 600 euros, but with a lower starting price.

3. Average Auction Price: The average auction price for this coin is 392.75 euros, which gives us an idea of its general market value.

4. Current Starting Price: The starting price is 125 euros, which is significantly lower than the average auction price.

5. Sales Trends: The coin has been auctioned 78 times, of which 72 have been successful sales. This indicates a consistent interest in the coin, which may influence its price.

Given all this, and considering that the coin's condition is relatively low (30), an estimated maximum purchase price could be in the range of 200 to 300 euros. This is based on the fact that, although the condition is not high, the interest in the coin and previous auction prices suggest that it could reach a higher price than the current starting price, but not so much as to approach the auction prices of coins in better condition.

Therefore, an estimated maximum purchase price could be 250 euros.
