2 Dollars - Elizabeth II Aquaman

Niue has long served as a convenient licensing vehicle for the New Zealand-administered territory's legal tender framework, allowing private mints — in this case the Perth Mint — to produce collectible issues that carry nominal face value under Niuean authority. The Aquaman release is part of a broader DC Comics series produced under that arrangement, with mintages typically capped to drive secondary market demand rather than any circulation function.
