So-Called Dollars are a type of commemorative medal or token that are not official coinage but are often recognized by collectors as part of numismatic history. The term originated from the 19th century, where these items were produced to commemorate significant events or figures, often in the form of larger denominations resembling a dollar, hence the name. One notable example is the So-Called Dollar from 1933, which was issued to commemorate the 1933 World’s Fair in Chicago. These pieces typically fall under the category of exonumia, which includes coins that are not intended for actual currency use. Collectors value So-Called Dollars for their historical significance and artistic design.
