Collectors want to be completely confident in the authenticity and provenance of their collectibles. As an item passes through many different hands, however, its authenticity and provenance can become increasingly uncertain. A member of the Certified Collectibles Group (CCG), Collectibles Authentication Guaranty (CAG) provides services that eliminate this uncertainty. By working directly with collectors, estates, artists, museums and others, CAG preserves the authenticity and provenance of collectibles, memorabilia and estate items at the source.
