So-Called Dollars are commemorative pieces issued primarily for expositions, fairs, or significant events, often designed to mark specific occasions. The Hibler and Kappen catalog serves as a reference for collectors, encompassing items produced between 1892 and onward. These coins typically feature unique designs and are not intended for general circulation, making them sought-after by numismatists. The term "unknown" may refer to pieces whose issuers or origins are not well-documented, adding an element of mystery to these collectibles.
