        "photo 1: the bag has a glossy, heavily finished black surface unlike the matte-to-satin glove-tanned leather typical of classic vintage Coach.",

        "Interior and label evidence are absent, preventing a meaningful creed, serial, lining, or country-of-origin consistency check."

    "possible_model_reasoning": [
        "No Coach model is assigned because the exterior lacks a creed, wordmark, hangtag, turnlock, or recognizable Coach construction.",
        "The approximately 11-inch width visible in photo 4 supports a medium handbag classification but is insufficient for model identification.",
        "Condition: approximately Very Good based on the clean exterior and intact visible stitching; interior, odor, lining, hardware function, and bottom corners are not fully shown."
