Based on the provided context, the Monetary Authority of Singapore (MAS) issued a new 20 dollar note in 2019 to commemorate the Singapore Bicentennial. The context itself, however, is limited as one source link leads to an unavailable service page.
Drawing upon general numismatic and historical knowledge to elaborate, the S$20 commemorative note was launched to mark the 200th anniversary of Sir Stamford Raffles' arrival in Singapore in 1819, a pivotal moment in the nation's history. The front of the polymer note features the portrait of Singapore's first President, Yusof Ishak, alongside the former Supreme Court and City Hall buildings.
The reverse side of the note is particularly significant for its depiction of eight key individuals who were pioneers in various fields during Singapore's early history. This design choice aimed to present a broader historical narrative, showcasing figures who made significant contributions to education, trade, and social development. The background portrays the Singapore River, illustrating the transition from a historic trading port to the modern city skyline of today. The note was issued for public circulation and is tender.
