5 Dollars - Charles III Red Dragon D20

The Red Dragon of Wales entered the British royal heraldic vocabulary centuries before the Windsor line existed, but its formal association with the Prince of Wales title — and by extension the heir apparent — was codified under Tudor precedent. Charles III used it as one of his personal heraldic supporters during his decades as Prince of Wales. This coin folds that heraldic history into a frankly unusual format: a twenty-sided die shape, a conceit borrowed from tabletop gaming culture that New Zealand Mint has deployed across several collector issues.

Niue's role here is purely fiduciary — the island nation licenses its monetary authority for exactly these kinds of novelty bullion programs.
