Is authentication the same as condition grading?
Authentication is verifying that an item is genuine — a real brand, not a counterfeit — through tags, stitching, hardware, and serials. It answers “is it real,” a separate question from condition grading, which answers “what shape is it in.” A bag can be authentic but worn, or fake but pristine, so resellers of luxury goods need both checks.
How it's used in a listing
A reseller who says “authenticated by a third party, EUC condition” is telling buyers the bag is verified genuine and separately rated for its light wear.
How it maps to the grade scale
Authentication and condition grading are different: authentication confirms genuineness; the GradeThread 1.0–10.0 scale rates condition. GradeThread grades condition, not authenticity — a fake in mint shape could still score a 9, which is why buyers of luxury goods need an authenticity check too.

Authentication — frequently asked
- Is condition grading the same as authentication?
- No. Authentication verifies an item is genuine and not counterfeit. Condition grading rates how worn or flawed it is on a scale. An item can be authentic but heavily used, or a well-made fake — so luxury resellers use both checks independently.
