250 Dollars - Charles III Harald Fairhair

Harald Fairhair's unification of Norway — traditionally dated to his victory at the Battle of Hafrsfjord, circa 872 AD — is the foundational event this coin commemorates, though historians still debate whether that battle represented genuine unification or simply the consolidation of southwestern Norwegian petty kingdoms. The accession of Charles III provided Niue, as a Commonwealth realm, with a new effigy requirement that triggered a wholesale refresh of its bullion and collector programs in 2023.

Niue's role as a Pacific island territory with a GDP dwarfed by its annual coin licensing revenue is worth noting — its issues are struck entirely for collector export, with essentially no domestic circulation.
