50 Tene - Elizabeth II FAO

The FAO series issued by Cook Islands in the late 1970s was part of a broader United Nations Food and Agriculture Organization program that encouraged member nations to mint coins carrying agricultural themes, with the explicit goal of promoting food security awareness. Cook Islands was among dozens of small-nation participants whose issues were partly subsidized through the program. The KM#6.3 designation distinguishes this from earlier variants in the series by a specific die modification to the reverse legend spacing — a distinction that matters more to variety collectors than to general circulation history.
