Why Slab Authentication Matters
Counterfeit graded slabs are a growing problem. Fake PSA 10s, altered BGS labels, and re-slabbed cards cost collectors thousands. Quick grade verification is your first line of defense.
🚨 Common Counterfeit Tactics
- Grade Bumping: PSA 9 label swapped into PSA 10 holder
- Company Swapping: SGC card re-slabbed as PSA
- Fake Holders: Entirely counterfeit slabs with fake cert numbers
- Photo Misrepresentation: Listing shows PSA 10, ships PSA 9
- Altered Labels: Grade numbers digitally edited in photos
⚠️ Real Cost: A fake PSA 10 of a $5,000 card could cost you $4,500+ if you don't verify before purchase.
✅ How Quick Detection Helps
- Instant Verification: Upload listing photo, confirm grade in 3 seconds
- Catch Alterations: AI detects if grade doesn't match slab appearance

💡 Pro Tip: Always verify cert numbers on grading company websites after purchase. This tool gives you the grade—full OCR gives you the cert.
