10 Dollars - Elizabeth II Daintree

Niue has issued commemorative silver under its own authority since the 1980s, leveraging its status as a self-governing territory in free association with New Zealand to mint coins that circulate nowhere and are produced entirely for the collector market. The Daintree issue belongs to a crowded field of such pieces — Niue produces dozens of collector releases annually through external minting partnerships, most commonly with the Perth Mint.

The Daintree rainforest in Queensland, Australia, is the oldest continuously surviving tropical rainforest on earth, dating back roughly 180 million years.
