Evidence

POSITIVE
  • photo 1: clearly a structured leather shoulder/tote-style handbag with leather straps and metal hardware
  • photo 3: visible horse-like embossed emblem on the front closure, though it is not a Coach horse-and-carriage mark
  • photo 4: construction appears to use leather panels, contrast trim, and relatively even stitching
  • photo 1,4,5: leather shoulder handbag with brass-tone hardware in vintage style
  • photo 5-6: seller-measured width ~7.5 in and height ~10-11 in, consistent with vintage shoulder bag scale
NEGATIVE
  • photo 3: front closure uses a large decorative equestrian-style medallion/clasp rather than a recognizable Coach turnlock or horse-and-carriage logo
  • photo 1: no legible COACH wordmark, creed patch, or Coach hangtag is visible
  • photo 2: rear zipper and hardware show no legible Coach branding
  • photos 1-7: glossy black-and-brown color-blocked construction and decorative clasp do not closely match the classic unlined glove-tanned Coach silhouettes shown in the reference catalog
  • photo 1-6: no COACH wordmark, horse-and-carriage, creed patch or leather hangtag visible
  • photo 3: front emblem is single horse in oval, not Coach carriage - lookalike brand cue
  • photo 3: front closure is large egg / oval clasp with hanging fob, not Coach slim rounded turnlock with flat back plate
  • photo 1,2,4: two-tone black body with contrasting brown trim/base/strap and large double O-ring strap attachments not a catalog Coach classic silhouette
  • photo 2: exterior back zip pocket with small leather pull - not typical Coach classic layout
MISSING INFORMATION
  • photo 1-7: interior is not shown; request a clear interior-wall and pocket photo for any creed or label
  • photo 1-7: no close-up of the underside/back of the front clasp or zipper pull
  • photo 1-7: country-of-origin or maker stamp is not shown
  • photo 1-7: bottom, side profile, and strap attachment details are incomplete
  • interior views not shown - lining and creed patch unknown
  • close-up of any interior leather patch or fabric brand label
  • hardware stamps / zipper brand on back zipper pull (photo 2)
  • bottom and corner wear detail
AUTHENTICITY CONCERNS
  • ⚠ photo 3: oversized decorative equestrian medallion clasp is a lookalike-brand cue rather than a typical vintage Coach identifier
  • ⚠ photo 1-7: absence of any visible Coach identifier prevents a Coach attribution; the bag may be an unrelated vintage or contemporary leather brand
  • ⚠ photo 3: single-horse embossed medallion is not Coach horse-and-carriage and matches Dooney & Bourke-type equestrian branding
  • ⚠ photo 3: egg-shaped front clasp with dangling fob does not match Coach turnlock geometry
