The Singapore $1 coin is made of a bi-metallic composition, specifically with a steel
CORE and a copper-plated steel outer ring. This design was introduced in 2013 as part of the fourth series of Singapore coins. Additionally, the coin features micro-engraving of the national flower, the Vanda Miss Joaquim, as a security measure.
