So Called Dollars are a type of medal or token that was primarily produced in the United States, often commemorating events, anniversaries, or notable figures. The Hibler-Kappen catalog, created by authors Hibler and Kappen, classifies these pieces, providing a systematic approach to their identification and valuation. The term "So Called Dollars" originates from the practice of issuing these items in a dollar size, even though they are not legal tender. An example is the So Called Dollar from 1881, which commemorates a specific event or figure from that year, although many pieces from this category remain unknown or not well-documented in terms of their origins or significance.
