Sports card grading has traditionally relied on human graders — but that’s changing.
Can AI grade sports cards better than humans?
TAG Grading (Technical Authentication & Grading) is one of the fastest-growing grading companies in the hobby, using artificial intelligence and digital scanning to evaluate cards.
In this review, we’ll break down how TAG works, its pros and cons, and whether it’s worth using in 2026.
Many collectors are drawn to TAG because AI grading offers something traditional grading often lacks: transparency.

TAG Grading is a strong option for collectors who value grading transparency, consistency, and modern technology. However, for maximum resale value, Professional Sports Authenticator still remains the market leader in most categories.
What Is TAG Grading?
TAG is a grading company that uses AI and advanced imaging technology to assess trading cards.
Unlike traditional grading companies that rely heavily on human evaluation, TAG uses:
- digital scanning

- defect mapping
- grading reports
This creates a more transparent grading process.
How Does TAG Grading Work?
TAG scans the card in high detail and analyzes defects across several grading categories.
- centering
- corners

- surface
Collectors receive a digital report showing exactly where flaws were detected.
