I believe this is an 8 piece collection and I have 9 pieces so 1 is a duplicate. The Yellow Rose called “The Peace Rose” is the duplicate. They are New in the Box. Some Paperwork is included. The Box contains a Top and Bottom Piece and some have an inner piece with a round circle to match the plate. Most include some foam liner to protect the Plate. You will receive a Plate, a Top and Bottom of the Box with each plate. I do not know the cost. You can go online and get an estimate. All Sales are Final.
