About CGC
CGC (Certified Guaranty Company) is part of the Certified Collectibles Group, the same parent company as NGC. While CGC built its reputation as the leading grading service for comic books and trading cards, they have expanded into coin grading through a dedicated coins division.
What CGC Is Known For
CGC brings the trusted Certified Collectibles Group brand and infrastructure to coin grading. As a sister company to NGC, CGC benefits from shared expertise and resources. CGC is still establishing its presence in the numismatic market, but the backing of the CCG brand gives it significant credibility.
For collectors who already use CGC for comics or trading cards and are familiar with their processes and holder quality, CGC coins offers a natural extension into numismatics.
Submission and Pricing
CGC's coin grading pricing and tiers are similar to NGC, as both operate under the Certified Collectibles Group umbrella. Visit their website for current submission forms and pricing details.
