1 Crown - Elizabeth II Platinum Jubilee

Ascension Island has no permanent civilian population and no domestic economy — its "coins" are legal tender in name only, issued exclusively for the collector market through arrangements with the Saint Helena government. The Platinum Jubilee series flooded the commemorative market in 2022, with dozens of issuers from Gibraltar to the Cook Islands producing near-identical crown-sized pieces. Ascension's contribution is platinum-plated base metal, a detail worth noting plainly: the word "platinum" in the name describes a surface treatment measured in microns, not the composition of the coin itself.
