1 Dollar - Elizabeth II 1st Anniversary of the euro

The euro itself launched on January 1, 2002, replacing the physical currencies of twelve eurozone nations simultaneously — the largest currency changeover in history by participating population. Cook Islands, a self-governing territory in free association with New Zealand, had no economic stake in that transition whatsoever, making this commemorative a straightforward numismatic souvenir rather than a coin with any organic connection to the event it marks.
