So-Called Dollars are a category of numismatic items that primarily refer to medals or tokens produced to commemorate significant events, places, or individuals, often with a dollar-sized format. The term originates from the monetary-like appearance of these items despite not being official currency. The Hibler-Kappen catalog, published in 1963, is a comprehensive reference that identifies various So-Called Dollars, including those issued for events in 1939. The 1939 Philadelphia So-Called Dollars include pieces celebrating the New York World's Fair and other notable occurrences of that year. Collectors value these items for their historical significance and artistic design.
