2 Dollars - Elizabeth II St. Nicolas

Niue has operated as a prolific bullion and commemorative issuer since the 1990s, licensing its monetary authority to third-party minting programs — primarily through the New Zealand Mint — that have little connection to the island's roughly 1,600 inhabitants. The face value is nominal; no one spends these.

The St. Nicolas issue falls within a wave of Christmas-themed silver rounds dressed as legal tender that flooded the collector market in the early 2010s, competing directly with private bullion rounds by leveraging sovereign status for added legitimacy.
