American Numismatic Association (ANA): The American Numismatic Association is a nonprofit educational organization dedicated to educating and encouraging people to study and collect money and related items. With nearly 33,000 members, the Association serves the academic community, collectors and the general public with an interest in numismatics.
The ANA helps all people discover and explore the world of money through its vast array of programs including its education and outreach, museum, library, publications, conventions and seminars.
American Numismatic Society (ANS): The American Numismatic Society is an organization dedicated to the study of coins, currency, medals, tokens, and related objects from all cultures, past and present. The Society's headquarters in New York City has the foremost research collection and library specialized in numismatics in the United States. These resources are used to support research and education in numismatics, for the benefit of academic specialists, serious collectors, professional numismatists, and the interested public.
Professional Numismatists Guild (PNG): The PNG is a nonprofit organization composed of the world's top rare coin, paper money and precious metals experts. As numismatic professionals, our primary mission is to make the hobby safe for collectors and investors by maintaining rigid standards of excellence for our member dealers. As a collector, investor or seller of coins, currency and precious metals, you should insist that your dealer be a member of the PNG.
Industry Council for Tangible Assets (ICTA): ICTA is the national trade association for all who have an interest in precious metals, rare coins, U.S. and foreign currency, and other numismatic and tangible assets. Since 1983, ICTA has been the numismatic industrys eyes and voice in Washington, DC. Without ICTA, the industry and hobby are subject to the whims of legislators, regulators, and bureaucrats who are eager to appease whatever special interest group gets their attention.
Professional Coin Grading Service (PCGS): In 1985, a small group of the nation’s leading coin experts, Bob Harwell Charter Dealer #15 and Jeff Garrett dealer #39 and others, recognized that for the rare coin industry to realize its potential, some serious problems needed to be addressed. Market participants soon became aware that one of the fundamental factors of determining rare coin values is the physical condition, or grade, of the coin. But due to the absence of a universal grading standard, they were caught in the middle of divergent definitions.
Numismatic Guaranty Corporation (NGC): NGC was founded in 1987. From the beginning NGC focused on only one objective, a standard of consistent and accurate grading. As NGC has grown to become one of the leaders in third-party grading services, and has maintained a steadfast and uncompromising commitment to this standard. The knowledge, integrity and dedication of NGC's team of grading experts ensures customers a level of grading consistency at the top, among grading services. This record of consistency, built over the years, has helped to foster greater stability throughout the rare coin marketplace.
