The first coin is from the Ming dynasty, a 10 cash coin minted under emperor TianQi, the 16th emperor. Value would be around 35-40 dollars. The second coin is from the Qing dynasty, a 50 cash coin minted under H'sien Feng, the 9th emperor. Value is around 90-100 dollars. Both coins have decent eye appeal and nice surfaces, and the larger denomination coins are generally more desirable.
