Kwangtung Mint was the China’s first coining facility to use modern technology. Its equipments were imported from the Heaton Mint in Birmingham, England, arriving in China in 1888.
When it opened, 90 minting machines operated at the same time. The U.S. Mint in Philadelphia was operating only six machines or fewer.
