Please know the owner of this copper coin and talk about its value.

Xianfeng was once the most chaotic era of the monetary system in Qing Dynasty. Xianfeng's money includes Bao Tong, Chongbao and Yuanbao, with different denominations, different textures, different casting bureaus and different versions. There are 500 kinds of Chongbao and 0/000 pieces of Yuanbao/KLOC. Some of them only see mother money and sample money, but they are not officially circulated. There is also a little-known fact that antique imitation began with imitation coins in the 1980s.

There is no problem with this picture in Chinese, but the width of the money edge is a problem. Say the value is only a few tens of dollars at most!
