". . . In the 1860s the Oriental Bank, the Chartered Bank of India, Australia and China and the Hong Kong and Shanghai Banking Company began issuing notes. Denominations issued in the 1860s and 1870s included 1, 5, 10, 25, 50, 100 and 500 dollars. These notes were not accepted by the Treasury for payment of government dues and taxes, although they were accepted for use by merchants. 25-dollar notes did not survive beyond the end of the 19th century, whilst the 1-dollar notes (issued only by the HSBC) were issued until 1935. 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, 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 shipment of 1941 1 cent coins was sunk, making this unissued coin very rare). Just before the Japanese occupation, an emergency issue of 1-dollar notes was made consisting of overprinted Bank of China 5-yuan notes. In 1945, paper money production resumed essentially unaltered from before the war, with the government issuing notes of 1, 5 and 10 cents and 1 dollar, and the three banks issuing notes of 5, 10, 50, 100 and 500 dollars. 1-dollar notes were replaced by coins in 1960, with only the 1-cent note issued by the government after 1965. In 1975, the 5-dollar notes were replaced by a coin, whilst 1000-dollar notes were introduced in 1977. The Mercantile Bank was absorbed by HSBC in 1978 and ceased issuing notes. In 1985, 20-dollar notes were introduced, whilst, in 1993, a 10-dollar coin was introduced and the banks stopped issuing 10-dollar notes. In 1994, the Hong Kong Monetary Authority (HKMA), gave authority to the Bank of China to issue notes. Between 1994 to 2002 an attempt was made to replace privately issued 10-dollar notes with coins issued by the government. In reponse to public demand for the continuation of a $10 note, the HKMA issued its own ten-dollar notes. Ten-dollar banknotes are currently the only denomination issued by the HKMA, having acquired the note printing plant at Tai Po from the De La Rue Group of the UK on behalf of the Government. The older (green) 10-dollar banknotes previously issued by two commercial banks are still circulating and remain legal tender, although they are being phased out since September 2005. These are popular for lai see and are noticeably scarce in the run up to Chinese New Year. The 1-cent note issued by the Government was demonetised and ceased to be legal tender on 1 October 1995. A commemorative polymer ten-dollar note was issued in July 2007 to commemorate the 10th anniversary of Hong Kong's return to China. The new note will circulate along with other 10-dollar issues for a trial period of two years, though the initial batch released was largely snapped up by collectors . . . The HKMA issues the 10-dollar note and the other three banks issue denominations of 20, 50, 100, 500 and 1000 dollars. In September 2009, Standard Chartered Bank issued the world's first 150-dollar denomination banknote. Approximately 750,000 notes were sold at above face value, in various combinations and presentations, as a commemorative charity issue. Although legal tender, the notes are unlikely to enter circulation, due to their rarity and expected higher re-sale value . . ." — Banknotes of the Hong Kong dollar at Wikipedia
