Based on these factors, an estimated maximum purchase price for this coin could be in the range of 30 to 40 euros. This is based on the historical hammer prices for coins with a similar condition and the general interest in the coin. However, since the condition is not high, it is wise not to exceed 40 euros in the bid.

Considering all these factors, an estimated maximum purchase price for this coin could be in the range of 70 to 90 euros. This is based on the average auction price and previous auction prices for coins with similar grades. However, since the grade is an important factor, it is likely that the price will be closer to the lower end of this range.

Therefore, a reasonable estimated maximum purchase price could be 80 euros.
