100 Dollars - Charles III Expo 2025

Expo 2025 opens in Osaka this year, the second time Japan has hosted a World's Fair — the first being Expo '70, also in Osaka, which drew 64 million visitors and remains the most-attended world's fair in history. Cook Islands has been one of the more aggressive sovereign issuers of commemorative bullion under licensing arrangements, and this piece falls squarely within that program rather than reflecting any direct Cook Islands connection to the exposition.
