2 Dollars - Elizabeth II Hawksbill Turtle

Niue's arrangement with the New Zealand Mint has produced dozens of wildlife-themed bullion issues, most of which track spot silver almost exactly and circulate purely as collector vehicles. The Hawksbill Turtle issue sits in that category without apology.

The hawksbill itself is listed as critically endangered under IUCN criteria, with global nesting populations estimated to have declined over 80% in the past century — a figure that lends the subject matter more weight than the typical Pacific island wildlife series.
