Certified Guaranty Company (CGC)
CGC is one of the fastest-growing grading companies in the trading card market, known for its modern approach, transparent grading standards, and strong presence across both sports and trading card games.
Black Label Grading began working with CGC in 2023 to give customers an alternative to the traditional grading companies, particularly for modern cards, trading card games, and high-volume submissions. CGC’s technology-driven processes and clear service tiers make it well suited to collectors who want speed, consistency, and strong market recognition.
CGC combines expert human graders with advanced imaging, verification, and tracking systems to authenticate, grade, and encapsulate cards securely. Their slabs and labels are widely accepted across the collecting and resale market, and their grading has become increasingly popular with both casual collectors and professional sellers.
