Hong Kong currently has only one auxiliary currency unit, the "cent", which is equivalent to 1/10 of the main currency "yuan", which is equivalent to the concept of the "jiao" of the RMB.

Historically, Hong Kong’s currency system was: 1 yuan = 10 cents = 100 cents (Cent’s transliteration, meaning cent) = 1,000 cents.

Currently there are only 5 cent coins in Hong Kong, which is equivalent to the RMB exchange rate of about 0.49 yuan, but it cannot be exchanged in mainland China. 50 cents is 4.9 yuan.

And Hong Kong has only minted 5 cent coins since 1951 (there were "half-round" silver coins before). Among them, there is a portrait of King George VI, and the market price is about 10 yuan. There are 4 types of portraits of Elizabeth II, generally priced at 1 to 3 yuan. There are two kinds of bauhinia patterns. The market price for the 1997 handover commemoration is about 2 yuan, and the ordinary one is up to 1 yuan. You also need to check when it was released.

If it is scarce, its value will be great
