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

1. Coin Condition: The coin has a condition rating of 70 (MS-), indicating that it is in acceptable condition but not of high quality. This generally affects the price, as coins in better condition tend to fetch higher prices.

2. Auction History:
- The average hammer price for similar coins has been 84.45 euros.
- In previous auctions, coins with a similar condition (70) have reached hammer prices that varied, but some examples are:
- 55 euros (2020-05-26)
- 54 euros (2018-12-11)
- 44 euros (2018-07-04)
- 60 euros (2021-06-22)
- 85 euros (2022-10-18)

3. Starting Price: The starting price is 30 euros, which is relatively low compared to previous hammer prices.

4. Price Trends: Looking at the history, it seems that the hammer price can vary significantly depending on demand at the time of the auction. However, the range of hammer prices for coins in similar conditions suggests that the price could be in the range of 50 to 85 euros.

Based on these factors, an estimated maximum purchase price for this coin could be between 70 and 90 euros, considering that collector interest and demand at the time of the auction can influence the final price. Therefore, a reasonable maximum purchase price could be 85 euros.

4. Starting Price and Average Starting Price: The current starting price is 75 euros, and the average starting price in the past has been 166.5 euros. This suggests that the current starting price is quite low compared to the historical average.

5. Recent Trends: In the most recent auctions, the hammer price has been 320 euros for a coin with a grade of 75, indicating that there is significant interest and value in coins of similar quality.

### Estimation of Maximum Purchase Price
Taking all these factors into account, an estimated maximum purchase price for the coin with a grade of 70 could be between 200 and 300 euros. This is based on the analysis of previous hammer prices and the price trend in recent auctions.

Therefore, a reasonable maximum purchase price could be 250 euros. This allows for some margin for competition in the auction, given that the starting price is relatively low.

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 Prices: By looking at previous auction prices for coins with a similar condition (70), we can see that they have reached varying hammer prices. For example, in past auctions, coins with a condition of 70 have reached hammer prices of up to 100 euros.

Based on these factors, an estimated maximum purchase price could be in the range of 90 to 110 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate.

Therefore, a reasonable estimated maximum purchase price for this coin could be 100 euros.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the coin's condition and previous auction prices.

1. Coin Condition: The coin has a condition rating of 70 (MBC-), indicating that it is in relatively good shape, but not of the highest quality (FDC).

2. Previous Auction Prices:
- In previous auctions, we have seen hammer prices that vary significantly. For example:
- In 2019, a similar coin was auctioned for 20 euros.
- In 2022, it was auctioned for 30 euros with a condition of 30.
- In 2022, another coin with a condition of 85 had a hammer price of 50 euros.

3. Average Hammer Price: The average hammer price for this coin is 57.75 euros, suggesting that, in general, coins of this reference tend to reach higher prices.

4. Starting Price: The starting price is 25 euros, which may be a good indicator of the sales expectation.

Given that the coin's condition is 70 and considering the previous hammer prices, an estimated maximum purchase price could be in the range of 40 to 60 euros. However, since the average hammer price is 57.75 euros, a reasonable maximum purchase price could be:

Estimated Maximum Purchase Price: 60 euros.

This price takes into account the coin's condition and previous hammer prices, as well as the market context.
