1 Dollar - Elizabeth II Brontosaurus

Cook Islands has operated as a prolific novelty mint licensing vehicle since the 1970s, issuing coins under its name through arrangements with private minting companies — primarily the Pobjoy Mint and later various European houses — with no expectation of actual circulation. This piece is a product of that machinery rather than any monetary need.

The name "Brontosaurus" was formally resurrected in 2015 when a reclassification study by Tschopp, Mateus, and Novas separated it from Apatosaurus — a split that had been contested since the original synonymization in 1903. The coin's naming follows that restoration.
