So-Called Dollars refer to commemorative medals that resemble U.S. dollar coins and were issued to mark significant events, centennial celebrations, or notable figures in American history. The term originates from a 1930 publication by Hibler and Kappen, which documented these pieces. In particular, the 1826 So-Called Dollar commemorates the Schuylkill Navigation Company and showcases intricate designs that reflect its historical significance. These collectibles are popular among numismatists for their unique blend of artistry and historical context.
