PENN CENTRAL LABELS

Does anyone know if OLD Penn Central Plates that used to be hanging on their trailers are worth anything now a day, Monetary or Historically.
I acquire a 2 of them they are pretty big about 3'x3' and also I have their trailer respective official #'s NYCZ and the number.
Thank you.

Offer them to a railroad museum or put them on eBay and see what you get. Everything is worth something to somebody.

Too big to put on eBay, expensive to ship. But they aught to be worth $50 or $75 anyways.
