30 Dollars - Elizabeth II Bounty

The Bounty has appeared on Cook Islands coinage almost continuously since the 1970s, making it one of the most enduring ship motifs in Pacific numismatics — not for sentimental reasons, but because the mutiny of 1789 deposited Fletcher Christian and eight other mutineers on Pitcairn Island, whose descendants eventually resettled on Norfolk Island. Cook Islands has no direct administrative connection to Pitcairn, but the region's broader Pacific identity made the subject a natural commercial anchor for the islands' prolific collector coin program.

The kilogram format in .9999 fine silver places this squarely in the bullion-plus-collector crossover market that dominated mint output in the late 2010s.
