2 Dollars - Elizabeth II Auspicious Koi

Niue has functioned as a prolific licensing vehicle for the New Zealand-managed Pacific mint trade since the 1990s, issuing collector coins under its name with essentially no connection to domestic monetary circulation. This koi-themed piece is one of hundreds of such issues — a legal-tender fiction that satisfies collectors and generates revenue for a nation of roughly 1,500 people with no meaningful coinage of its own.

The KM#4858a suffix suggests a variant within a numbered type, likely distinguished by a colorized or gilded finish from a base issue.
