Collectible coins come in various types, including commemorative issues and So-Called Dollars, which are medallions often produced to commemorate specific events or themes. The Hibler and Kappen reference pertains to a catalog that documents So-Called Dollars, particularly those minted around the American Bicentennial in 1976. Among collectible denominations, the 50 cent coin, often referred to as a half dollar, has historical significance in the United States, with specific variants like the Kennedy half dollar being particularly sought after by collectors.
