Evidence

POSITIVE
  • photo 2: clearly a handbag with a compact structured silhouette and top handle
  • photo 1: visible stamped wording reads "GENUINE LEATHER LINING," indicating a leather-lined interior
NEGATIVE
  • photo 2: glossy black patent-like exterior and generic rectangular frame silhouette do not resemble a typical vintage Coach glove-tanned leather classic
  • photo 1: visible lining stamp is not a Coach creed and shows no Coach wordmark or serial format
  • photo 3: interior appears leather-lined rather than the unlined suede-backed construction common to many classic vintage Coach bags
  • photo 2: no visible Coach hangtag, horse-and-carriage mark, or recognizable Coach model feature
  • photo 4: hardware and strap construction appear generic; no legible Coach engraving is visible
  • photo 1: interior stamp reads GENUINE LEATHER LINING, not a Coach creed patch with No. line
  • photo 1-4: no COACH wordmark, horse-and-carriage, or hangtag visible
  • photo 2-4: black patent frame / kisslock-clasp top-handle silhouette with rigid frame - not a catalog Coach classic silhouette
  • photo 2-4: high-gloss patent leather exterior, not glove-tanned cowhide with suede-back unlined interior
  • photo 3: tan leather lining with center zip compartment, not unlined suede-back glove-tanned construction
MISSING INFORMATION
  • photo 1: a straight-on, close-up photograph of the entire interior and all pockets
  • photo 2: exterior back, bottom, side seams, and corners
  • photo 3: close-up photographs of the clasp, zipper pulls, and strap attachment hardware
  • photo 1: any interior leather patch, fabric tag, or maker label is not shown
  • photo 1-4: no Coach creed patch shown - request straight-on interior back wall/pocket in raking light
  • photo 1-4: no maker mark, country line, or serial visible - request any interior stamps or labels
  • photo 2-4: exterior bottom, corners and side views not shown
  • photo 1,3: zipper brand stamp not legible
AUTHENTICITY CONCERNS
  • ⚠ photo 1: the only visible stamp says "GENUINE LEATHER LINING," not a Coach creed or Coach-specific identifier
  • ⚠ photo 2: patent-like finish and generic frame-bag construction are inconsistent with the most recognizable vintage Coach classic construction
