Wow, what a piece. Brilliant yellow olive W.U. 5 Patent Dec.19.1871. There is a little mold defect on the upper wire ridge that appears to have been from a little air pocket. It is not a chip. There also appears to be a tiny stone in the glass there which probably caused the little defect. I would say this piece is very close to factory mint but let's go VNM to be safe. Asking $1350 plus shipping.
