Evidence

POSITIVE
  • photo 1: leather crossbody handbag with a vintage-style rectangular flap silhouette
  • photo 3: visible long shoulder strap and folded gusseted sides
  • photo 6: leather construction and a metal snap closure are visible
NEGATIVE
  • photo 1: no visible COACH wordmark, horse-and-carriage, creed patch, hangtag, or recognizable Coach hardware
  • photo 2: highly glossy, vertically segmented leather is not characteristic of classic Coach glove-tanned construction
  • photo 6: closure appears to be a simple snap rather than a Coach-style turnlock
  • photo 3: strap attachment and side construction do not visibly match a clearly identifiable Coach catalog model
  • listing text: seller describes the item only as vintage brown leather and does not provide a Coach attribution
MISSING INFORMATION
  • photo 6: interior is partly obscured by the decorative frame; request a fully unobstructed interior view
  • request a straight-on close-up of every interior wall and pocket for a creed or brand label
  • request close-ups of the snap, strap attachment points, and any zipper or hardware markings
  • request bottom, corner, edge, and full strap-condition photos
  • request seller-stated dimensions and confirmation of material composition
AUTHENTICITY CONCERNS
  • ⚠ No Coach identifier is visible, so the bag currently reads more like a generic vintage leather crossbody than an identifiable Coach piece
  • ⚠ The glossy segmented leather and simple snap closure are inconsistent with the most recognizable classic Coach glove-tanned turnlock styles
