Chinese cash coin cast during the reign of Emperor Gao Zong (1736-1795). The inscription reads qian long tong bao and the coin was produced by the Board of Revenue in Peking (Beijing). This is a very common coin. Both images are upside-down so rotate the coin 180 degrees for the correct orientation. Gary
Could I ask another favour please? Any idea on this coin. Don't worry too much about a full ID. I don't want to take up too much of your time. A point in the right direction would be great.
