2 Dollars - Charles III Treasures of ancient civilizations IV

Niue has operated as a prolific licensing jurisdiction for commemorative bullion since the 1990s, contracting its sovereign authority to third-party minting programs that bear little connection to the island's 1,600 residents. This particular piece belongs to a long-running "Treasures of Ancient Civilizations" series, the fourth installment, issued under Charles III following Elizabeth II's death in September 2022 — making the regnal attribution here a straightforward administrative update rather than any meaningful numismatic distinction.
