To estimate a maximum purchase price for the coin in question, we can analyze the provided data:

1. Current starting price: 60 euros.
2. Average starting price in previous auctions: 87.63 euros.
3. Average hammer price in previous auctions: 123.2 euros.
4. Hammer price history: Hammer prices have varied, with a maximum of 170 euros in previous auctions.

Since there is no information about the condition of the coin, it is difficult to make an accurate estimate. However, we can consider the highest hammer prices and the average hammer price to establish a range.

- Maximum previous hammer price: 170 euros.
- Average hammer price: 123.2 euros.

Considering that the starting price is 60 euros and that the average hammer price is significantly higher, we could estimate a maximum purchase price that is within a reasonable range above the starting price, but does not reach the historical maximum.

A reasonable estimate could be between the average hammer price and a bit more, considering that the coin may not be in the best condition. Therefore, an estimated maximum purchase price could be:

Estimated maximum purchase price: 130 euros.

This price reflects a balance between the average hammer price and the potential of the coin in the market, taking into account the lack of information about its condition.

Based on the data provided, we can see that the coin in question has had an average auction closing price of 21.58 euros in previous auctions. Additionally, the current condition of the coin is 95 (EBC+), indicating that it is in quite good condition.

Considering that the average auction closing price has been 21.58 euros and the high condition of the coin, we could estimate a maximum purchase price around 25-30 euros.

It is important to note that the final auction price may vary depending on factors such as competition from other bidders, interest in the coin at that specific time, and buyers' willingness to pay a higher price for a coin in good condition with a history of successful auctions.
