150 Dollars - Elizabeth II Bounty

The 2014 Cook Islands 150-dollar Bounty issue is part of a long-running series that has made the Cook Islands one of the most prolific issuing authorities in the large-format silver market — a status that has nothing to do with the islands' domestic economy and everything to do with licensing arrangements with overseas mints and distributors. At 5 kilograms of .9999 silver, this is a bullion-adjacent collector piece rather than anything resembling circulating currency.

The Bounty itself ran aground on a reef off Pitcairn Island in January 1790, deliberately scuttled by Fletcher Christian to prevent recapture. Pitcairn remains a British Overseas Territory; Cook Islands, by contrast, is in free association with New Zealand — which is precisely why neither has a meaningful historical claim to the ship.
