Collectible coins encompass a wide range of types, including commemorative coins, numismatic coins, and historical pieces. In the United States, collectible coins often feature denominations such as the fifty-cent piece, commonly known as the half dollar. So-called dollars refer to medals or tokens that resemble U.S. dollars but are not legal tender, with many designed for commemorative purposes. The Hibler and Kappen catalog is a recognized reference for collectors of so-called dollars, providing detailed descriptions and valuation information for these unique items.
