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

1. Starting Price: 200 euros. This is the initial price set for the auction.
2. Condition: The coin has a condition rating of 70 (VF-), indicating that it is in fairly good shape, although not the best possible condition.
3. Auction History: The coin has been auctioned once in the past, with a starting price of 400 euros and a hammer price of 850 euros. This suggests that there is significant interest in this coin, and the hammer price was considerably higher than the starting price.
4. Average Starting and Hammer Prices: The average starting price is 300 euros, and the average hammer price is 850 euros. This reinforces the idea that the coin has good selling potential.

Given that the coin has a history of successful sales and a hammer price that significantly exceeds the starting price, and considering its condition, an estimated maximum purchase price could be positioned in a range between the average hammer price and the previous hammer price.

Therefore, an estimated maximum purchase price could be around 800 to 900 euros. This is based on the demonstrated interest in previous auctions and the condition of the coin.

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-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Current Starting Price and Previous Prices: The current starting price is 650 euros. In previous auctions, we have seen hammer prices that vary depending on the condition. For example, in recent auctions, coins with similar conditions have reached hammer prices of up to 800 euros.

3. Price Trends: The average hammer price for similar coins is 585.1 euros, suggesting that the hammer price may be in a similar range or slightly above the starting price.

4. Sales History: The coin has been auctioned 84 times, with a high sales percentage (82 out of 84). This indicates a consistent interest in this coin, which may influence the price.

5. Recent Hammer Prices: In the most recent auctions, hammer prices have been in the range of 700 to 900 euros for coins with similar conditions.

Taking all these factors into account, an estimated maximum purchase price for this coin could be between 800 and 900 euros, considering that the interest in the coin and its condition could lead to a higher than usual hammer price.

Therefore, a reasonable maximum purchase price could be 850 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-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Auction History:
- The average hammer price of similar coins in the past has been 849.85 euros.
- In previous auctions, coins with a similar condition (70 and 75) have reached hammer prices that varied, but some examples are:
- 1200 euros (2022, condition 70)
- 2100 euros (2023, condition 85)
- 850 euros (2020, condition 80)
- The trend shows that coins with a condition of 70 have had hammer prices ranging between 600 and 1200 euros.

3. Starting Price and Average Starting Price:
- The current starting price is 600 euros, which is a good starting point.
- The average starting price of 479.46 euros suggests that the current starting price is competitive.

4. Demand and Supply: The coin has been auctioned 27 times in the past, with a sell-through rate of 96.3% (26 out of 27). This indicates a consistent interest in this coin.

Based on these factors, an estimated maximum purchase price could be between 1000 and 1200 euros, considering that the condition is slightly lower than the coins that have reached higher prices, but still, the interest and sales history suggest it could fetch a good price at auction.

Therefore, a reasonable maximum purchase price could be 1100 euros.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, including the current condition of the coin, previous auction prices, and behavior in past auctions.
