About CGZ Grading
At CGZ Grading, we’re redefining what it means to protect, authenticate, and collect trading cards—while rewarding your passion along the way. Backed by 40 years of industry experience, 5 years of grading service, and 1,000+ cards graded, CGZ also delivered the first real-time AI grading code available free for public use in 2020.
Our technology & grading philosophy
We combine AI-assisted analysis with human expertise to deliver a faster, smarter grading experience. Each card we grade, auction, or sell receives a unique certification number, adding an extra layer of traceability.
Every graded card is added to the CGZ Population Report so collectors can verify authenticity and view details.
- • CGZ inventory-first approach (fewer unknown sellers)

- • Affordable options + frequent deals
- • Careful packing and shipping
At CGZ, we’re not trying to be everything—we’re focused on what matters most: giving collectors a trusted, affordable, and rewarding place to buy and protect the cards they love.
