Proof issues were made by the
Oriental Bank Corporation and the
Bank of Hindustan, China and Japan during the 1860s. However, due to the low price level in that era, those notes are currently extremely rare. It was not until 31 March 1977 that the first circulating note was issued by the HSBC with a dimension of 100mm by 173mm. Later on 6 March 1979, the Standard Chartered Bank (Hong Kong) issued its own one thousand-dollar note, with a dimension of 100mm by 170mm. Since 1985, the note issued by both banks were redesigned with a shrunk size of 81.5mm by 163mm. In 1988, a lighter shade of gold was used by the HSBC as the previous selection of colour was overly dark. The same change could also be seen on the twenty-dollar note and the one hundred-dollar note of HSBC during this decade. As the date of the
transfer of sovereignty over Hong Kong was approaching, the two note-issuing banks modified their design in 1993 to tune down the British elements. In 1994, the Bank of China became the third note-issuing bank in the territory. Changes of design were made in the year 2003, 2010 and subsequently in 2018 to add in new security features. ==Nickname of the notes==
