1 Dollar - Elizabeth II Mountain Gorilla

Niue's status as a Cook Islands-adjacent Pacific microstate with a population under 2,000 has made it one of the most prolific coin-issuing authorities in the world relative to its size — a function of a 1989 agreement with New Zealand that allows it to issue legal tender while outsourcing monetary infrastructure entirely. The mountain gorilla series falls squarely within a wave of wildlife-themed silver issues marketed to thematic collectors rather than circulating users.

The mountain gorilla population, confined to the Virunga volcanic range and Bwindi Impenetrable Forest, numbered fewer than 880 individuals at the time of striking.
