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 average hammer price for similar coins in the past is 28.43 euros.
- The last auction with a known hammer price for a coin of similar condition (80) was 25 euros, suggesting that the market is willing to pay in that range.

3. Starting Prices and Estimates:
- The current starting price is 25 euros, and the average starting price in the past has been 21.93 euros. This indicates that the current starting price is reasonable and aligns with historical data.

4. Price Trends:
- In previous auctions, hammer prices have varied, but there are examples of coins in similar conditions that have reached hammer prices of up to 95 euros (in the case of a coin with a condition of 95).

5. Supply and Demand: Since there are no scheduled auctions in the coming days for this coin, there could be increased demand at the time of the current auction.

Taking all these factors into account, an estimated maximum purchase price for this coin could be in the range of 40 to 60 euros. This is based on the current condition, price history, and market trends. However, it is important to remember that the final price may vary depending on competition in the auction and the interest of other buyers.

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 fairly good shape, but not of the highest quality (FDC).

2. Auction History:
- The average hammer price for similar coins has been 80.88 euros.
- In the past, coins with a similar condition (75) have had hammer prices that varied, with examples selling for 35 euros (2019-07-03) and 60 euros (2018-10-16).

3. Starting Price: The starting price is 30 euros, which may be a good indicator of the expected sale.

4. Recent Trends: In the most recent auctions, the hammer price has shown a trend of being higher, with examples of hammer prices of 65 euros (2024-07-11) and 160 euros (2024-09-19) for coins of similar condition.

5. Average Hammer Price: Given that the average hammer price is 80.88 euros, this suggests that, in general, coins of this reference tend to sell for higher prices.

### Maximum Purchase Price Estimate
Taking all these factors into account, a reasonable maximum purchase price for this coin could be between 70 and 90 euros. This is based on the historical hammer prices for coins of similar condition and the average hammer price.

Therefore, an estimated maximum purchase price could be approximately 85 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 70 (VF-), indicating that it is in relatively good shape, but not among the best qualities.

2. Auction History:
- The average hammer price in previous auctions is 72.54 euros.
- The average starting price is 59.95 euros.
- In the past, hammer prices have varied significantly, ranging from 20 euros to 200 euros, depending on the condition and demand at the time of the auction.

3. Recent Trends:
- In the most recent auctions, hammer prices have been in a range of 45 to 65 euros for similar conditions (75-85).
- The last auction with a hammer price of 60 euros for a condition of 85 suggests that the market is willing to pay more for coins in better condition.

4. Starting Price: The starting price is 35 euros, indicating that the seller expects a lower price initially, but this does not necessarily reflect the true value of the coin.

Based on these factors, an estimated maximum purchase price for the coin, considering its condition and price history, could be between 70 and 90 euros. This is because, although the condition is not the highest, the interest in VF- quality coins may lead to a hammer price that approaches the higher levels observed in the past.

Therefore, a reasonable estimated maximum purchase price could be 80 euros.
