RR TRAIN ENGINE MEDALION

I have an ATLANTIC COAST LINE ENGINE TRAIN MEDALLION that was mounted on the front of the engine nose, about 22" in diameter, made of at least 1/8" thick steel and it is porcelainized with Atlantic Coast Line as the center inscription printed in 3 classic script lines, and 6 different states that they operated in at that time, inscripted around the perimeter of the sign face in block letters. In order to ship this sign to protect it, I will need to construct a thin wooden box, which I will have to charge for to build, so that cost will be an added cost over the purchase of the medallion, plus then the shipping cost has to be added. This came off from a train engine being decommissioned/dismantled in roughly 1958/60 era. NOTE: this medallion is pristine, no chips in the porcelain, the sign is near to original manufacture perfect, and weights about 22/25 pounds. Contact me if interested and provide to me your Zip Code location, so I can quote to you a total purchase/ship cost.
