1 Dollar - Elizabeth II Aureus Diana

Niue has served as a convenient licensing jurisdiction for privately designed bullion and numismatic issues since the 1990s, with the New Zealand dependency lending its legal tender framework to dozens of foreign-marketed collector coins annually. The "Aureus" branding here is a marketing convention applied by the issuing company — likely the Polish Mint or a similar contractor — rather than anything connected to Roman gold coinage beyond the name.

Diana issues in this format were produced in limited runs aimed squarely at the European collector market.
