100 Dollars - Charles III Baby Sugar Glider

Niue's revenue from numismatic licensing has long outpaced anything its 1,600-odd residents could generate through conventional trade, and the island's arrangement with New Zealand — which handles its foreign affairs and defence — gives it the unusual position of issuing coins bearing the British monarch's effigy while operating essentially as a self-governing collector-coin factory. This particular piece belongs to the ongoing Australian wildlife series that has proven reliably commercial across the precious metals market.

Sugar gliders are marsupials, not rodents, despite appearances — a distinction Australian naturalists spent considerable effort establishing in the 19th century.
