So-Called Dollars are a category of medals, primarily from the 19th and early 20th centuries, issued to commemorate significant events or anniversaries, often related to the United States. They are not official currency but hold collectible value among numismatists. The Hibler-Kappen catalog serves as a reference for collectors, detailing various so-called dollars, which include pieces like those minted in 1908 that celebrate events such as expositions or commemorative occasions. Many of these pieces are striking in design and may be made from various metals, contributing to their appeal and value in the collectible market.
