Evidence

POSITIVE
  • photo 1: clearly a shoulder handbag with a zippered top and attached strap.
  • photo 1: brown trim and ring hardware are visible, but they do not show distinctive Coach construction or branding.
NEGATIVE
  • photo 1: body is black textile with prominent multicolor embroidered butterfly decoration, unlike the solid leather, suede, or recognized Coach signature-canvas styles expected for the likely vintage Coach population.
  • photo 1: no visible Coach wordmark, horse-and-carriage, creed patch, or leather Coach hangtag.
  • photo 2: large round rings and textile construction are generic and do not resemble a Coach turnlock-based classic.
  • photo 5: zipper and trim appear generic, with no visible Coach-marked hardware.
  • listing title: seller identifies it as an Old Navy bag, which is consistent with the mass-market textile construction, though the title is untrusted and not photographic evidence.
  • photo 1,2,4: black woven fabric / canvas body with large colorful embroidery, not glove-tanned leather
  • photo 1,2,3,4: zip-top hobo silhouette with large O-ring strap attachments, no turnlock, no creed patch, no COACH wordmark
  • photo 5: unbranded base-metal zipper slider and thin faux-leather pull, not Talon/YKK solid brass
  • photo 6: plain black fabric back with no leather, no brass hardware, inconsistent with vintage Coach classics
MISSING INFORMATION
  • photo 2: interior emptied and photographed, including any labels, creed-like patch, or fabric tags.
  • photo 5: close-up of all hardware and zipper pulls for any maker marks.
  • photo 1: dimensions and material confirmation for the brown trim and strap.
  • photo of interior lining and any brand tag to confirm maker
  • photo of bottom and close-up of strap wear (for condition cap)
AUTHENTICITY CONCERNS
  • ⚠ photo 1: textile body, decorative embroidery, and generic hardware provide no evidence of Coach manufacture and are inconsistent with the classic vintage Coach leather-bag profile.
  • ⚠ photo 2: visible construction is more consistent with a non-Coach mass-market embroidered bag than a Coach model.
