So-Called Dollars refer to a category of commemorative medals and tokens that resemble dollar coins but are not actual currency. They were issued primarily in the United States and often commemorate significant events or milestones. The Hibler and Kappen reference likely pertains to the cataloging system used for these collectibles, where the authors document various types and examples, including those from 1897. The designation "Unknown" may signify pieces whose origins, manufacturers, or specific commemorative purpose are not fully documented.
