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.

Why collectors use CGZ
  • • CGZ inventory-first approach (fewer unknown sellers)
  • • Clear slab verification via cert ID + pop report
  • • 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.
