1 Dollar - Charles III Slovenia

Niue has operated as a prolific bullion and collector coin issuer since the 1990s under a licensing arrangement with New Zealand, whose currency it uses for domestic transactions. The island's own GDP is negligible, so coin programs of this type function almost entirely as export revenue — the "Niue dollar" exists on paper but not in pockets. The amber insert here is a Baltic amber inclusion, a technique increasingly used by Polish and Czech minting houses contracting for Pacific island issuers.
