So-Called Dollars are a type of commemorative medal that emerged in the United States during the late 19th century, particularly around the 1898 period. They are typically named after the person or event they commemorate and are often designed to resemble dollar coins, although they are not official currency. These pieces were produced for various events, such as expositions or anniversaries, and are collected for their historical significance and artistic design. The SC 1 designation refers to the first entry in the catalog of So-Called Dollars, often considered a key piece in the genre.
