Like the paper bill, the copper coins issued by the Central Mint also had "Chinese Soviet Republic" (中華蘇維埃共和國) in traditional Chinese characters engraved, and due to the fact that coins last longer than paper bills, these coins were issued and circulated in much greater numbers. However, these coins are currently rarer than the paper bill, mainly because the copper used was in need of cartridges, so these copper coins were recalled and replaced by silver dollars.
