About 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 grading companies.

The CCG Companies

NCS evaluates all certified or raw coins, tokens and medals, and is able to remove 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.
