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

1. Starting Price: 35 euros, which is the initial price of the auction.
2. Current Condition: 30 (BC+), indicating a fairly low condition compared to the historical reference which has a condition of 70.
3. Previous Prices: In the 2019 auction, the coin with a condition of 70 sold for 80 euros, with a starting price of 75 euros and an estimated price of 125 euros.

Since the condition of the current coin is significantly lower (30 compared to 70), this will affect the final price.

The average hammer price of similar coins in the past is 62.5 euros, but since the condition is much lower, it is reasonable to adjust this price downward.

We can consider that, due to the low condition, the maximum purchase price could be in the range of 20 to 30 euros, as the condition drastically affects the value.

Therefore, an estimated maximum purchase price could be around 25 euros. This is a conservative value, taking into account the low condition and the price history.

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 30 (BC+), indicating that it is not in the best condition. This will affect its value compared to coins in better condition.

2. Auction History: The coin has been auctioned 77 times, of which it has sold 69 times. This suggests there is consistent interest in the coin, although the non-sale rate (8 times) also indicates that the desired price is not always reached.

3. Starting and Hammer Prices: The current starting price is 20 euros, and the average hammer price in the past has been 58.22 euros. This suggests that, on average, similar coins have achieved a significantly higher value than their starting price.

4. Previous Prices: Looking at the hammer prices of coins with similar conditions (around 30-40), prices have varied, but some have reached up to 90 euros in similar conditions.

5. Recent Trends: In the most recent auctions, hammer prices have shown a range that may indicate an increase in interest or value for the coin.

Based on these factors, an estimated maximum purchase price for this coin could be between 40 and 60 euros, considering that the average hammer price is 58.22 euros and that the condition is not optimal. A price of 50 euros could be a reasonable target, as it falls in the middle of this range and takes the condition into account.

3. Previous Prices:
- In the auction of October 2022, the coin with a condition of 75 had an estimated price of 350 euros, but the hammer price is unknown. This suggests that the value of the coin may be high, but there may also be fluctuations in the market.
- In the auction of April 2022, a coin with a condition of 80 sold for 70 euros, indicating that condition significantly affects the price.

4. Current Starting Price: The starting price is 100 euros, which may be a good starting point for the auction.

Taking all these factors into account, an estimated maximum purchase price could be in a range between 85 and 120 euros, considering that the average hammer price is 85 euros and the average starting price is 113.33 euros.

5. Previous prices: In the most recent auction, the coin was offered with a starting price of 80 euros and sold for 420 euros, showing significant interest and an increase in value.

Given that the condition of this coin is good and considering the auction price history, an estimated maximum purchase price could be in a range between the average hammer price and the starting price.

Taking all these factors into account, an estimated maximum purchase price could be around 350 to 400 euros. This is based on the interest shown in previous auctions and the condition of the coin.

Taking these factors into account, an estimated maximum purchase price could be slightly above the previous average hammer price, but considering the condition, it may be wise not to exceed too much.

Estimated maximum purchase price: 50 euros.

This price reflects an interest in the coin, but also takes into account its condition and price history.

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