5 Dollars - Elizabeth II Protect our World

Niue's early 1990s commemorative program leaned heavily on licensed themes sold through distribution partnerships, particularly with the New Zealand Mint. The "Protect our World" series was part of a broader wave of Pacific island conservation-themed coinage that flooded the collector market in this period — issues designed primarily for the bullion-adjacent gift trade rather than any domestic monetary purpose. At .500 fineness, this sits well below sterling, a cost-reduction choice common to Niue's issues of this era.
