        "photo 1: neither purse matches a confidently identifiable Coach handbag model; both are small kiss-lock coin purses and are better treated as generic vintage accessories.",

        "photo 3: the burgundy purse's chevron decoration and fabric lining are generic design cues, not Coach-specific evidence.",
        "Condition: Good for the lot; photo 3 shows substantial interior discoloration and wear in the burgundy purse, while photo 2 shows marks and aging in the off-white lining. Exterior condition is only partially assessable."
