The series, released by Monetary Authority of Singapore (MAS), comprise a cupro-nickel coin of two Singapore dollars, a silver coin of five Singapore dollars and a gold coin of 50 Singapore dollars.
Themed "Education, Building Our Nation Together", the set of coins reflects the fundamental role education has played in the transformation of Singapore, China's state-run Xinhua news agency reported.
The cupro-nickel coin features basic education at the primary and secondary levels, which equips children with the foundational skills and the character and values that prepare them for the future.
Singapore's Minister of Education and Chairman of the SG50 Steering Committee Heng Swee Kiat launched the first batch of three SG50 coins at an event attended by over 11,000 people, including educationists.
Singapore's multi-racial diversity is depicted in all three designs. The back of the coins bear the Singapore Coat of Arms with the year 2015.
To be issued on May 28, the set of coins leads a series of commemorative notes that will be issued in the second half of this year.
