        "photo 1: lot consists of four handbags, but none visibly shows a Coach wordmark, horse-and-carriage, creed patch, or recognizable Coach hardware.",

        "photo 7: green bag's glossy embossed material, bright silver-tone hardware, and triangular decorative closure are lookalike-fashion construction cues rather than vintage Coach cues."

    "possible_model_reasoning": [
        "No Coach model is supported: the visible silhouettes and closures do not match the cataloged Coach classics, and no Coach identifier is visible.",
        "photo 6: the yellow bag's lined construction and decorative resin ring suggest a modern generic fashion bag rather than a pre-2000 Coach classic.",
        "Condition: approximately Good to Very Good for the visible lot; bags appear usable, but the yellow bag has visible edge wear and the green bag has surface creasing\/scuffing. Interior and odor conditions remain unknown."
