1976, the Hong Kong government made the first quarter coin with copper-nickel alloy. On the one hand, the portrait of Queen Elizabeth II was cast, and on the other hand, the face value of "Hong Kong Wuyuan" was cast. However, because it is too easy to be stolen, the Hong Kong government changed to cast a round 5-yuan coin with a safe edge at 1980. The words "Wuyuan, Hong Kong, Hong Kong, five yuan" are cast on the safety edge, and the hollow "5" is cast in the middle of the front to replace the royal British lion holding pearls in Decathlon era. 1985, the face was replaced by the queen wearing a crown, and she looked mature. 1993 The design was changed to match the handover of sovereignty in Hong Kong, with bauhinia on the front. 1997, to commemorate the reunification, another commemorative coin with the pattern of five bats and mice was cast. All these special issues are still in circulation today.
