2 Dollars - Elizabeth II Poseidon

The Poseidon issue is part of Cook Islands' long-running collaboration with the European Mint, which has produced an enormous volume of high-relief, antiqued silver pieces marketed primarily to collectors rather than circulating users. Cook Islands holds legal authority to issue coinage under its status as a self-governing territory in free association with New Zealand, an arrangement that has made it one of the more prolific issuers of numismatic-grade silver in the Pacific — producing far more collector pieces than its population of roughly 17,000 could ever require.
