        "photo 1: The bag is shown with a visible non-Coach-looking script wordmark and no Coach wordmark or horse-and-carriage.",

        "photo 4: The hardware is small gold-tone plated hardware and the bag has ordinary zipper closures, not a vintage Coach turnlock.",
        "photo 4: The seller's stated material is vegan leather, which strongly weighs against a vintage Coach leather handbag.",
        "photo 5: Product graphics identify the item as a new modern retail-style bag, not a vintage Coach piece.",

        "No creed patch, Coach identifier, serial\/style number, or Coach hangtag is visible."

    "possible_model_reasoning": [
        "No Coach model is supported: the silhouette is a generic structured satchel and lacks a Coach creed, wordmark, turnlock, hangtag, or recognizable Coach-specific construction.",

        "Condition appears New\/unused based on the product graphics and seller statement, but this is a modern non-Coach item; interior and bottom condition are not independently verifiable from the listing photos."
