2 Dollars - Elizabeth II Tetris

Niue has operated as a prolific licensing hub for novelty bullion since the 1990s, its sovereignty making it legally capable of issuing currency while New Zealand handles its actual monetary affairs. The Tetris license here is legitimate — The Tetris Company has actively pursued branded collectible agreements since the mid-2010s, and this coin is an official product of that effort rather than a generic gaming tribute.

The 2019 release incorporated color printing and reportedly sound-chip technology in some packaging variants, though the coin itself is straightforward one-troy-ounce silver.
