100 Dollars - Elizabeth II Green and Golden Bell Frog

Niue's wildlife coin programs occupy a peculiar corner of the numismatic market — sovereign legal tender struck for a Pacific island of roughly 1,600 people, underwritten entirely by collector demand rather than any domestic economy. This piece belongs to a series highlighting endangered Australasian species; the Green and Golden Bell Frog (Litoria aurea) was once one of the most abundant frogs on the Australian eastern seaboard before chytrid fungus and habitat loss collapsed populations dramatically through the 1980s and 1990s.

One troy ounce of .9999 fine gold for a frog that nearly vanished from the continent entirely.
