About the Collectors Society
The Collectors Society offers membership plans for coin, note or comic collectors — whether beginner or advanced. Members gain access to grading services and interactive forums, exclusive hobby education, essential population and pricing data, and much more.
Introduced by the Certified Collectibles Group (CCG), the Collectors Society is built on the expertise of the industry’s top independent collectibles grading and conservation companies.
The CCG Companies
Numismatic Guaranty Corporation
Founded in 1987, NGC is the world’s leading and largest third-party grading company. The company’s expertise in coin certification is paralleled by its commitment to educating and empowering collectors through the NGC Collectors Society, with resources like the NGC Registry, VarietyPlus®, the NGC Coin Explorer, interactive forums and free access to the NGC coin price guide.
NGC certifies and encapsulates US, World and ancient coins in its innovative and industry-leading EdgeView® Holder — the same rigorously tested and used by the Smithsonian to preserve and protect their most valuable coins. NGC offers Details Grading for coins with detrimental surface conditions, and is the only grading company to offer both Plus and Star Designations. NGC is proud to be the official grading service of the Professional Numismatists Guild (PNG) and the American Numismatic Association (ANA).
Numismatic Conservation Services
Founded in February 2001, NCS provides professional coin conservation services for dealers and collectors, with a pledge of integrity, impartiality and responsibility.
NCS evaluates all certified or raw coins, tokens and medals, and is able to remove harmful surface contaminants such as PVC, soils, tarnish, carbon spots, verdigris and encrustation from surfaces. Removing detrimental material from the surface of an item may dramatically improve its appearance and eye appeal. This service is designed to preserve the material and prevent the damage that can result from contamination that is left untreated. NCS does not perform repairs or mechanical alterations of any kind.
NCS is the official conservation service of the ANA and PNG.
