5 Dollars - Elizabeth II Velociraptor

Niue has operated as a prolific licensing hub for commemorative coinage since the 1990s, contracting its monetary authority to external minting programs while the island's roughly 1,500 residents use New Zealand dollars for actual commerce. This piece belongs to a wave of natural history issues that flooded the collector market in the early 2020s, competing directly with similar programs from Cook Islands, Palau, and Tuvalu.

KM#4508 is a 2 oz silver issue — the weight already tells that story without repeating it. What the catalog number won't tell you: Niue's name appears on hundreds of such coins annually, with production contracted primarily through the New Zealand Mint and the Polish Mennica Polska facility.
