2 Seniti - Taufa'ahau Tupou IV FAO

Issued as part of the FAO coinage program, which ran through the 1970s and prompted dozens of nations to strike commemorative and circulating pieces tied to the United Nations Food and Agriculture Organization's campaigns against hunger. Tonga's participation reflected Taufa'ahau Tupou IV's broader push to modernize the kingdom's institutions — he had personally overseen the establishment of the National Reserve Bank itself in 1971, just four years before this series began.

FAO-linked issues from small Pacific states are frequently overlooked by collectors, which keeps acquisition costs low despite genuinely limited original distribution.
