To estimate a maximum purchase price for the coin in question, we can analyze 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 fetch higher prices.

2. Auction History:
- The coin has been auctioned 11 times, of which it has sold 9 times. This indicates good demand.
- The average hammer price in previous auctions is 297.22 euros, suggesting that, in general, coins of this reference tend to sell for relatively high prices.

3. Previous Prices:
- Looking at previous hammer prices, we can see that they have varied considerably, from 135 euros to 700 euros, depending on the condition and other factors.
- The last auction in which a coin with a similar condition (70) was sold had a hammer price of 210 euros.

4. Starting Price and Average Starting Price:
- The current starting price is 100 euros, which is quite low compared to the average hammer price of 297.22 euros.

5. Price Trends:
- Since the average hammer price is significantly higher than the starting price, this suggests that there is potential for the coin to sell for a higher price.

Based on these factors, an estimated maximum purchase price could be in the range of 250 to 300 euros, considering that the condition is 70 and that the price history shows that coins in similar conditions have reached hammer prices in that range.

Therefore, a reasonable maximum purchase price could be approximately 280 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 of 70 (MBC-). This is an important factor, as coins in better condition tend to reach higher prices.

3. Average Auction Price: The average auction price for this coin is 874.66 euros, which gives us an idea of the general market value.

4. Starting Price: The starting price is 200 euros, indicating that the auctioneer expects a low initial price compared to previous auction prices.

5. Recent Trends: In the most recent auctions, the auction prices have varied, but they have remained in a range that suggests demand for this coin is still strong.

Based on these factors, an estimated maximum purchase price for the coin with a condition of 70 could be in the range of 600 to 800 euros. This is based on the fact that, although the condition is not the highest, there is a history of auction prices suggesting it could reach a significant value at auction.

Therefore, a reasonable maximum purchase price could be 800 euros.

To estimate a maximum purchase price for the coin in question, let's consider several factors:

1. Current Condition: The coin has a condition of 70 (VF-), which is lower than the conditions of previously auctioned coins (75). This could influence the price, as a lower condition generally translates to a lower price.

2. Previous Prices:
- In the December 2020 auction, the coin sold for 200 euros, which was both the starting price and the final price.
- In the May 2023 auction, the coin sold for 310 euros, although the starting price was 200 euros. This indicates an increase in interest or value of the coin in the market.

3. Average Hammer Price: The average hammer price for this coin is 255 euros, which can serve as a good indicator of the current market value.

4. Market Trends: Since the coin had a higher hammer price in the most recent auction, this suggests that interest in the coin may be increasing.

Taking these factors into account, an estimated maximum purchase price could be between the average hammer price (255 euros) and the most recent highest hammer price (310 euros). However, since the current condition is lower than previous ones, it is reasonable to adjust downwards.

Therefore, an estimated maximum purchase price could be around 280 euros. This reflects a balance between the increasing interest in the coin and its current condition.

3. Starting Price and Average Starting Price:
- The current starting price is 100 euros, which is relatively low compared to the average hammer price.
- The average starting price has been 113 euros, suggesting that the current starting price is competitive.

4. Market Trends: Given that the coin has been auctioned 54 times and has a sell-through rate of 90.74% (49 out of 54), this indicates consistent demand.

Based on these factors, an estimated maximum purchase price could be between 220 and 250 euros, considering that the condition is good and there are precedents for sales in that range. This also takes into account the possibility that some bidders may be willing to pay more for a coin in good condition.

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