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.

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