So-Called Dollars are a type of commemorative medal or token that originated in the United States during the late 19th and early 20th centuries, often produced for special events or anniversaries. The Hibler and Kappen catalog, first published in 1970, documents these pieces, including the 1948 examples, which were created to commemorate significant occasions, such as the California Gold Rush or various expositions. While they are not officially recognized as currency, So-Called Dollars are collected for their historical significance, artistic design, and connection to American cultural events.
