50 Cents - Charles III Zeus

Niue's bullion and collector coinage is struck under contract by foreign mints and authorized under a longstanding arrangement that allows the island territory — population under 2,000 — to generate revenue through numismatic licensing. The Zeus theme places this in a broader series of classical mythology issues that Niue has produced prolifically since the 2010s, largely targeting the collector market rather than any domestic circulation need.

At 0.0311 g, this is a one-tenth-grain gold piece — among the smallest gold coins commercially produced anywhere.
