5 Baht - Rama IX King's Mother

Issued to commemorate the 84th birthday of Princess Srinagarindra, mother of King Bhumibol Adulyadej, this coin marks a milestone in Thai royal commemoration coinage — the princess lived to 94 and remained an extraordinarily active public figure, founding numerous rural development and mobile health clinic programs that continued operating well after her death in 1995. The choice of 84 held particular numerological significance in Thai Buddhist tradition, representing a full twelve cycles of the seven-year cycle.
