5 Dollars - Elizabeth II Monarch Butterfly

Cook Islands has long served as a licensing vehicle for novelty bullion issues produced by outside mints — this piece is one such product, with the Pacific island nation lending its name and nominal issuing authority to a coin almost certainly struck in Europe or North America. The monarch butterfly subject fits squarely within a wave of nature-themed silver rounds that flooded the collector market in the early 2020s, most targeting the one-troy-ounce bullion buyer rather than the numismatic collector.

Mintage figures for Cook Islands issues of this type are rarely independently audited.
