In Singapore, the side of the coin that features the national Coat of Arms is conventionally considered "heads." The Singapore Coat of Arms is the national emblem, which displays a shield with a crescent moon and five stars, supported by a lion and a tiger. Below the animals is a blue ribbon with the motto "Majulah Singapura."
The opposite side of the coin, which shows the denomination (e.g., 5 Cents, 10 Cents, $1) along with a design of local flora or a landmark, is considered "tails." For example, the one-dollar coin features the Vanda 'Miss Joaquim' orchid on its tails side, while the 50-cent coin depicts the Port of Singapore. This convention aligns with the common practice of identifying the side with the national emblem or a sovereign's portrait as heads.
