        "photo 2: the rounded flap, woven panels, beadwork, and leather edging do not closely match a listed Coach classic model; no Coach model candidate is supportable",
        "photo 1-6: dating is uncertain because no label, creed, serial, or country-of-origin mark is visible; the construction is more consistent with a later handmade artisan bag than with a pre-2000 Coach classic",
        "photo 1-6: condition appears Very Good from the exterior, with intact woven panels and leather; interior, odor, and lining condition are unknown, so the grade cannot be higher than Very Good"
