Under the Currency Ordinance of 1935, banknotes in denominations of 5 dollars and above issued by the three authorised local banks, the Mercantile Bank of India Limited, the Chartered Bank of India, Australia and China and the Hong Kong and Shanghai Banking Corporation, were all declared legal tender. The government took over production of 1 dollar notes. In 1941, the government introduced notes for 1, 5 and 10 cents due to the difficulty of transporting coins to Hong Kong caused by the Second World War (a ship carrying 1941 1-cent coins was sunk, making this unissued coin very rare).
