DESIGNER STAMP SPECIFICATION & FORMAT AUDIT 10 DESIGNER BRANDS · 47 UK HANDBAG MODELS · GBP (£)
Mandatory Non-Authentication, Superfake & Zero-Liability Notice: (1) Format Match ≠ Authentic Bag (Superfakes Slip Through): High-grade counterfeits (“superfakes”) routinely copy and clone genuine serial numbers, date codes, and blind stamps from real bags. A matching code format only means the sequence fits historical production records; a counterfeit bag carrying a cloned sequence can and will pass a code-only check. (2) Zero Liability / Informational Benchmark Only: The Atelier Index (Carly Litwin trading as The Atelier Index) is an independent editorial archive and statistical price index. We never physically inspect handbags, never issue certificates of authenticity, and accept zero liability or financial responsibility for any purchase, sale, authentication dispute, or loss on third-party marketplaces (eBay, Vinted, Vestiaire Collective, auction houses, or private sales). (3) Pro-Authenticity & Non-Affiliation: We are strictly pro-authenticity and anti-counterfeit: our tool exists to help collectors spot obvious factory/date mismatches early and to steer buyers toward authorised boutiques and physical multi-point authentication before any funds change hands. Independent publication under UK nominative fair-dealing principles; not affiliated with, endorsed by, authorised by, or sponsored by any designer brand.

  • Deeply machine-routed, overly thick tree trunk on the brass fob or wrong font kerning on the word MULBERRY.
