2 Dollars - Charles III Tetrimino T

Niue has long served as a licensing vehicle for the New Zealand-administered territory's coin program, which generates revenue through collectible issues rather than circulating currency. This piece belongs to a tetromino-themed series built around the geometric puzzle pieces popularized by Alexey Pajitnov's 1985 Soviet-developed game — the T-tetromino being the four-square T-shaped piece central to the game's mechanics. The series is designed to interlock physically with other pieces in the set.

Charles III's effigy appears here as the nominal issuing authority, though his accession in September 2022 means this is among the earlier commercial issues to carry his portrait under the Niue license.
