5 Dollars - Elizabeth II Sidney Crosby

Cook Islands has issued commemorative silver dollars under licensing agreements with sports properties for decades, but this particular release ties to Crosby's status at the time as the reigning back-to-back Stanley Cup champion — Pittsburgh had won in both 2016 and 2017, making him the dominant figure in the sport at the moment of striking. The Cook Islands nominal face value carries no practical monetary function; these pieces enter the market directly as collectibles through licensed distributors.
