1 Dollar World's Fair of Money, silver plated

Ascension Island — a British Overseas Territory with no permanent indigenous population — has issued commemorative coinage for decades under arrangements that have little to do with local monetary needs and everything to do with the collector market. The "World's Fair of Money" is an annual convention run by the American Numismatic Association, and pieces timed to its release are typically sold on the show floor as souvenirs.

The silver-plated composition rather than solid silver puts this squarely in the promotional tier of modern numismatic issues.
