Chinese Resellers

The economic history of China during most of the Qing dynasty was based on the silver from the Spanish Indies.
The real de a ocho became the foundation of trade between China and the West from the 16th to the 19th century, so successful that it extended to Indian, Japanese, and Indonesian trade.
By adopting foreign currencies into the Chinese monetary system, the reselling technique was used for control and verification of the weight, authenticity, and purity of silver pieces.
The variety of stamps or marks (punched, geometric, figurative) and the placement of the stamp affect their meaning, and they complement each other to indicate technical aspects of the piece, region, or dates.
All of this makes every resold piece unique, and no two are the same.
