2 Dollars - Elizabeth II The Riddler

Niue has operated as a licensing vehicle for themed bullion and collector coinage since the early 2000s, leveraging its status as a New Zealand realm territory to issue legal tender struck almost exclusively for overseas collectors. The Riddler release is part of a broader DC Comics licensing arrangement that has produced dozens of character-specific coins across multiple issuers. These are manufactured for the collector market and see no circulation whatsoever — Niue's resident population is under 2,000.
