1 Dollar - Charles III Hummingbird

Niue has operated as a vehicle for New Zealand-backed commemorative coinage since the 1970s, licensing its monetary authority to mint programs with essentially no connection to the island's 1,500-person population. The arrangement is straightforward: revenue from collector sales flows to the issuing mint, Niue lends its legal tender status, and the coins never circulate.

KM#6775 sits in a catalog stretching into the thousands for this issuer alone — a volume that reflects the scale of the licensing industry rather than any numismatic rarity.
