Orchid series 1967 The Orchid Series of currency notes is the earliest to be in for circulation in Singapore. Issued in the years 1967 to 1976, it has nine denominations: $1, $5, $10, $25, $50, $100, $500, $1,000, and $10,000. Each note has an
orchid design in the centre of the note's front, the orchid being the national flower of Singapore. A scene of Singapore is depicted on the back, which varies across denominations. Standard on each note, is the
Coat of Arms, a
lion head watermark, and the signature of the Minister for Finance and chairman of the BCCS, on the front of the note. As an added security feature, all notes have at least one vertically embedded security thread, while the $10,000 note has two.
Bird series 1976 The Bird Series of currency notes is the second set of notes to be issued for circulation in Singapore. Issued in the years 1976 to 1984, it has nine denominations, the same number as in the
Orchid Series, albeit the $25 note was replaced by the $20 note. Each note features a bird on the left side of the note's front, a theme selected to represent a young Singapore "ever ready to take flight to greater heights". Standard on each note, is the
Coat of Arms, a
lion head watermark, and the signature of the Minister for Finance and chairman of the BCCS, on the front of the note. As an added security feature, all notes have a vertically embedded security thread, while the $1,000 and $10,000 notes have two.
Ship series (1984–1991) The Ship Series of currency notes is the third set of notes to be issued for circulation in Singapore. Issued in the years 1984 to 1999, it retains the number of denominations as was in the previous two series of notes, but switches the $20 note for the $2 one. A maritime theme to reflect Singapore's maritime heritage was adopted, and progressively shows across the various denominations, the different kinds of ships which have plied Singapore's waters as the country developed. These vignettes are located on the front of the note. On the back, various scenes depicting Singapore's achievements are shown, as well as an
orchid, to symbolise the country's national flower. Standard on each note, is the
Coat of Arms, a
lion head watermark, and the signature of the Minister for Finance and chairman of the BCCS, on the front of the note. As an added security feature, all notes have a vertically embedded security thread.
Portrait series (1999) The current Portrait series was introduced in 1999, with the one- and 500-dollar denominations omitted. These notes feature the face of
Yusof bin Ishak, the first president of the Republic of Singapore, on the obverse, and the reverse depicts a feature of civic virtue. There are both paper and polymer notes in circulation. The designs of the polymer notes are very similar to the corresponding paper note except for the slightly slippery feel and a small transparent window design in the corner of the banknote. Polymer notes are progressively replacing the paper banknotes in circulation. The notes also have Braille patterns at the top right-hand corner of the front design. The S$10,000 and
B$10,000 note are the world's most valuable banknotes (that are officially in circulation). As of August 2011, it is worth over seven times as much as the next most valuable, the 1,000-
Swiss franc note. On 2 July 2014, the
Monetary Authority of Singapore announced that it would stop printing $10,000 notes starting from 1 October 2014 to reduce the risk of money laundering, with all banks instructed to exchange the notes with MAS and not recirculate them. This is a trend in many countries like
European Central Bank's discontinuation of the 500-
euro banknote in 2016 and AMBD's announcement to stop the production and issuance of the B$10,000 (the largest banknote) in 2020 amid the
COVID-19 pandemic. MAS would also stop producing the S$1,000 banknote as well from 1 January 2021 onwards, but banks would be allowed to recirculate existing notes with customers. The MAS said that the higher denomination notes (beyond $100) will continue to remain legal tender. A circulation version of the $20 note can be exchanged at banks in Singapore beginning 16 July 2007, limited to two pieces per transaction. On 18 August 2015, to commemorate Singapore's 50 years of nation-building, the Monetary Authority of Singapore launched a set of six commemorative notes. These commemorative notes comprise five S$10 polymer notes and a S$50 note. The note design's draw inspiration from significant milestones and achievements in Singapore's history, the multiracialism that defines the nation and the values and aspirations that underpin Singapore's progress. The front of both the $50 and $10 notes feature a portrait of Yusof Ishak, Singapore's first president, as in the current Portrait series notes. In 2017, to commemorate the 50th anniversary of its
Currency Interchangeability Agreement between
Brunei and
Singapore, both the
Monetary Authority of Brunei Darussalam and the
Monetary Authority of Singapore issued $50 polymer banknotes to commemorate that event. == Exchange rates ==
