National Commemorative & Expo So-Called Dollars

About This Series

Preserving the medallic record of America's great expositions and national celebrations, so-called dollars are medal-sized commemorative pieces — typically around 38 mm, approximating the silver dollar — issued for world's fairs, international expositions, and major anniversary events. The Hibler-Kappen reference (with Fuld updates) provides the standard HK numbering system. Beginning with the 1876 Centennial Exhibition in Philadelphia, the series documents grand expositions showcasing American achievement: the 1893 Columbian Exposition in Chicago, 1904 Louisiana Purchase Exposition in St. Louis, 1915 Panama-Pacific Exposition in San Francisco, and dozens of smaller celebrations. Struck in silver, aluminum, bronze, and gilt across various sizes, these range from exquisitely designed official souvenirs to crude promotional pieces, offering collecting opportunities at every price point. The "so-called" designation acknowledges their dollar-like size without claiming monetary status. For collectors, the series provides a three-dimensional history of American public celebration, each piece tied to a specific event whose story enriches the numismatic object.
