You DID post this under "parts for sale".If it aint about the money or the historical value what else is there? What is your definition of a market?

Ebay is the best market for them. Flea market is the only other one. If you don't need money put them on ebay for $0.01. If you have any valuable ones they'll be bid on if not some dealer will take them off your hands cheap.

I have a friend who was selling them on ebay but the market is going away. The demand is getting smaller while the supply keeps growing. Bent or rusted plates have almost no value at all. Thank god they're not restored or they might actually be worth something.
