The Certified Collectibles Group (CCG) is a set of independent third-party companies focused on the expert authentication, grading and conservation of collectibles.
The Certified Collectibles Group (CCG) comprises five of the world’s leading collectible coin, paper money and comic book service companies: Numismatic Guaranty Corporation (NGC), Numismatic Conservation Services (NCS), Paper Money Guaranty (PMG), Certified Guaranty Company (CGC) and Classic Collectible Services (CCS). Headquartered in Sarasota Florida, CCG has locations in Germany, Hong Kong, China, South Korea, Singapore and Japan.
NGC is the world’s leading and largest third-party coin grading service, and its affiliate NCS was the first professional coin conservation company. PMG was founded in 2005 and is now the world’s largest third-party paper money grading service. CGC set the standard for third-party comic book, magazine, lobby card and vintage photograph grading, and its affiliate CCS performs expert pressing, restoration and restoration removal services for comic books.
These services share a common approach that is rooted in complete independence and objectivity. CCG companies do not buy or sell collectibles, and their employees are prohibited from commercial trading to prevent conflicts of interest. In addition, a submitter’s identity is always concealed from the experts who handle their submission. These measures ensure a fully impartial expert opinion. Those who submit collectibles to a CCG member company can count on the integrity, expertise and reliability of a proven process. The services provided by CCG member companies add transparency to the market and give greater confidence to buyers and sellers around the world.
