10 Dollars - Elizabeth II 4th Portrait - Little Spotted Kiwi, Silver Proof Gilded

New Zealand's little spotted kiwi (Apteryx owenii) is functionally extinct on the mainland, surviving only through managed island populations — most significantly on Kapiti Island, where a relocation program beginning in the 1890s preserved the species from the predator-driven collapse that eliminated it everywhere else. By the time this coin was struck, the total wild population had recovered to roughly 1,700 individuals, entirely the result of sustained conservation intervention over more than a century.
