TAG (Technical Authentication and Grading) represents the newest evolution in card grading, using computer vision and machine learning alongside human expertise to grade cards. Their 1000-point scoring system is the most granular in the industry, providing precise numerical grades rather than broad tier categories.
Unlike traditional grading companies that rely primarily on human assessment, TAG uses high-resolution imaging and computer vision algorithms to measure centering, detect surface imperfections, evaluate corner sharpness, and assess edge quality. This technology-forward approach aims to eliminate inconsistency — the same card scanned twice should receive the same score.
TAG's digital certificate system goes beyond the physical slab. Each graded card has a digital twin accessible via QR code, showing the complete scoring breakdown, high-resolution images, and verification data. This transparency sets a new standard for what collectors can expect from a grading service.
Warning signs that a TAG slab may not be authentic
Every TAG slab has a QR code linking to its digital certificate. Missing or non-functional QR codes indicate a counterfeit.
TAG’s digital twin should match the physical slab exactly. Any discrepancy in score, description, or images is a red flag.
If the card’s visible condition doesn’t match the numerical score (e.g., a 980 on a clearly worn card), the label may be fake.
TAG uses modern case designs with specific construction quality. Poor case quality suggests counterfeiting.
Every TAG graded card exists in their portal system. No record means fake.
TAG’s app-based verification should confirm the slab. If verification fails, proceed with caution.
