Evidence

POSITIVE
  • photo 1: clearly a leather shoulder/crossbody handbag with an adjustable strap
  • photo 2: exterior wordmark visibly reads Stone Mountain, not COACH
  • photo 3: buckle is visibly engraved Stone Mountain
  • photo 6: interior construction and lining are clearly shown
NEGATIVE
  • photo 2: visible Stone Mountain branding directly identifies another maker
  • photo 3: hardware is branded Stone Mountain rather than unmarked vintage Coach hardware
  • photo 6: bag has a fabric/synthetic lining, unlike many classic unlined glove-tanned Coach styles
  • photo 1: silhouette is a generic soft leather shoulder bag without a recognizable Coach-specific identifier
  • photo 2: no Coach wordmark, carriage, creed patch, or Coach hangtag is visible
MISSING INFORMATION
  • photo 6: no close-up of every interior label or care/manufacturing tag is provided
  • photo 1: bottom and all corner details are not shown closely
  • photo 3: buckle is shown, but zipper-pull branding and other hardware details are not separately documented
AUTHENTICITY CONCERNS
  • ⚠ photo 2: Stone Mountain branding is inconsistent with Coach manufacture; this is a non-Coach lookalike/other-brand bag rather than an apparent Coach item
