100 Dollars - Charles III Hawaii

Hawaii was never part of Charles III's realm, but the kingdom that bore that name spent decades in a peculiar diplomatic limbo — recognized by foreign powers including Britain, yet perpetually under pressure from American commercial interests who ultimately engineered its annexation in 1893. The Cook Islands has built a substantial business issuing large-format silver pieces commemorating historical episodes well outside its own history, a practice underwritten by collector demand rather than any administrative connection to the subject matter.

At a kilogram of four-nines silver struck to 100mm, this is squarely in the "statement piece" tier of modern numismatic issues — produced for display cabinets, not pockets.
