250 Dollars - Elizabeth II Game Flip Coin

Niue has operated as a prolific licensing vehicle for novelty bullion since the 1990s, with the New Zealand government backing its coinage authority despite the island's population hovering around 1,500. The "Game Flip Coin" concept — a struck piece mechanically designed to mimic a fair coin toss — occupies an awkward commercial niche between functional bullion and themed collectible.

At one troy ounce of .9999 gold, the underlying metal content is genuine enough.
