Hello, if it is HK$ 500 issued by the Bank of China, there is no counterfeit money, but it does not rule out that criminals forge counterfeit money. If they charge HK$ 500, please pay attention to identification. On May 1994, China Bank issued Hong Kong banknotes for the first time. There are five denominations of issued Hong Kong banknotes, namely HK$ 20, HK$ 50, 100, HK$ 500 and 1000. The same as the face value distribution of the Hong Kong dollar at that time. Later, in the 2003 edition and the 20 10 edition of Hong Kong dollars, these five denominations of banknotes were still retained. The Hong Kong dollars issued by the Bank of China were all signed by the general manager of the Bank of China Hong Kong Branch at that time. For example, the 1994 version of BOC HK$ bears the machine-printed signature of Mr. Zhou Zhenxing, then general manager of Hong Kong Branch.
