10 Seniti - Salote Tupou III

Salote Tupou III ruled Tonga for nearly four decades and became internationally known largely through a single moment: her open-carriage appearance in the rain at Elizabeth II's 1953 coronation, which made her one of the most talked-about figures at the ceremony. This 1967 issue was struck just one year before her death, during the final phase of a reign that had steered Tonga through Japanese occupation in World War II without formal invasion of the main island group.

Tonga would achieve full independence from British protection in 1970 — she did not live to see it.
