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. Previous Auction Prices: By observing the hammer prices of coins with similar conditions (80 and 85), we can see that the hammer prices have varied considerably. For example:
- In 2020, a coin with a condition of 80 sold for 110 euros.
- In 2018, another coin with a condition of 80 sold for 80 euros.
- In 2022, a coin with a condition of 80 sold for 213 euros.

3. Average Hammer Price: The average hammer price for this coin is 165.94 euros, which gives us a good reference for what buyers are willing to pay.

4. Starting Price and Estimates: The starting price is 60 euros, and the average starting price is 57.62 euros. This suggests that the starting price is reasonable and could attract buyers.

5. Auction Trends: Given that it has been auctioned 70 times in the past and sold 63 times, this indicates good demand for this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 200 to 300 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 according to the competition.

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 70 (MBC-), indicating that it is in quite good shape. This generally translates to a higher value compared to coins with lower conditions.

2. Auction History:
- The average hammer price for coins with a similar condition (70) has been between 45 and 100 euros in previous auctions.
- In the most recent auctions, the hammer price for coins with a condition of 70 has ranged from 55 to 85 euros.

3. Starting Price and Previous Prices:
- The current starting price is 25 euros, which is relatively low compared to the average hammer price of 118 euros.
- The average starting price in previous auctions has been 49.63 euros, suggesting that the current starting price may be underestimated.

4. Auction Trends:
- The coin has been auctioned 49 times, with an 81.6% sell-through rate, indicating good demand.
- There are 3 auctions scheduled in the coming days, which could increase competition and the final price.

Based on these factors, an estimated maximum purchase price for this coin could be between 80 and 120 euros, considering that the hammer price may be influenced by demand at the auction and the coin's condition. A price of 100 euros could be a reasonable target, given the price history and condition.

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+). 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 64.55 euros.
- In previous auctions, hammer prices have varied, with some reaching up to 270 euros in similar or better conditions.

5. Future Projections: There are 3 auctions scheduled in the coming days, which may influence competition and interest in the coin.

Based on these factors, an estimated maximum purchase price could be in the range of 70 to 90 euros, considering that the condition is good and that the price history shows that coins in similar conditions have reached higher prices in the past. However, since the starting price is 30 euros, it is likely that the hammer price will not significantly exceed the previous average hammer price.

Therefore, a reasonable 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. Coin Condition: The coin has a condition of 70 (MBC-), indicating that it is in an acceptable state, but not of high quality. This may influence the price, as coins in better condition tend to fetch higher prices.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the current condition of the coin (80, MBC+) and the hammer prices from previous auctions with similar conditions.

1. Current Condition: The coin has a condition of 80 (MBC+). This indicates that it is in relatively good shape, but not of the highest quality (FDC).

2. Previous Hammer Prices: By observing the hammer prices of coins with similar conditions (around 80-85), we can see that the hammer prices have varied, but generally, they have been in a range of approximately 260 to 380 euros.

3. Starting Price and Average Hammer Price: The current starting price is 400 euros, which is higher than the average hammer price of 299.08 euros. This suggests that the seller has high expectations, but the market may not be willing to pay that much.

4. Price Trends: In previous auctions, hammer prices for coins with conditions of 80-85 have reached up to 360 euros in some cases. However, the highest recorded hammer price for a similar condition was 380 euros.

5. Final Estimate: Given that the condition of the coin is 80 and considering the previous hammer prices, an estimated maximum purchase price could be around 360-380 euros. This is based on the analysis of price trends and the condition of the coin.

Therefore, an estimated maximum purchase price for this coin could be approximately 360 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 80 (MS+). This is an important factor, as coins in better condition tend to fetch higher prices.

Based on these factors, an estimated maximum purchase price could be around 350-370 euros. This is based on the analysis of previous hammer prices and the current condition of the coin.

To estimate a maximum purchase price for the coin with a grade of 85 (EBC-), we can analyze historical data from previous auctions of coins with a similar grade and their hammer prices.

1. Relevant data from previous auctions:
- In the past, coins with a grade of 85 have had hammer prices ranging from 316 to 401 euros.
- For example:

- 2020-11-10: Hammer price 340 euros (grade 85).
- 2023-02-16: Hammer price 375 euros (grade 95, but in a similar range).
- 2023-01-31: Hammer price 420 euros (grade 90).

2. Analysis of starting and hammer prices:
- The current starting price is 400 euros, which is slightly higher than the average hammer price of similar coins in the past (323.88 euros).
- However, the average hammer price for coins with a grade of 85 has been higher on some occasions, reaching up to 401 euros.

3. Estimation of the maximum purchase price:
- Given that the starting price is 400 euros and considering that the hammer price for coins with a grade of 85 has reached up to 401 euros, a reasonable maximum purchase price could be slightly above the starting price, but not much higher to avoid overpaying.
- Therefore, an estimated maximum purchase price could be 450 euros. This allows for a margin to compete in the auction without exceeding the historical value of the coin too much.

In summary, the estimated maximum purchase price for the coin with a grade of 85 would be 450 euros.

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

For example, in recent auctions, coins with conditions of 80-90 have reached hammer prices ranging from 320 to 400 euros.

4. Recent Trends: In the most recent auctions, hammer prices for coins of similar condition have been in the range of 360 to 400 euros, suggesting that interest and value for these coins are on the rise.

5. Maximum Price Estimate: Given that the condition of the coin is good and considering previous hammer prices, a reasonable maximum purchase price could be in the range of 450 to 500 euros. This is based on the trend that coins in good condition tend to reach higher prices at auctions.

Therefore, the estimated maximum purchase price for this coin could be approximately 500 euros.

To estimate a maximum purchase price for the coin that will be auctioned, we will consider several factors, including the starting price, the condition of the coin, and the hammer prices from previous auctions of coins with similar conditions.

### Relevant Data:
- Starting Price: 400 euros
- Condition of this Coin: 80 (MBC+)
- Previous Prices for this Coin:
- In previous auctions, coins with a condition of 80 have had hammer prices ranging from 200 to 400 euros, with an average hammer price of around 320 euros.
