Medal Collectors of America (MCA) was founded in August 1998 at the Portland, Oregon, convention of the American Numismatic Association (ANA). Its primary purpose was to serve collectors of world and U.S. art and historical medals. MCA would bring together those interested in collecting, research and publication of research concerning art and historical medals.

MCA exists to serve the collector of art and historical medals. Its publication, The MCA Advisory and this MCA website provide a forum for research, news and views in the field of medallic art. MCA encourages research and publication and recognizes excellence through its annual Carl W.A. Carlson Award and Georgia Stamm Chamberlain Award. With nearly two decades of steady growth under its belt, MCA is here to stay as the spokesman of a significant but long-neglected area of numismatics in this country.
