Any companies take base plates in trade?

Anyone know if any companies will buy used base plates or take them in trade. I've got three now that I've taken off different toads. Two Blue Ox and One RoadMaster. Of course, I'm going to have to buy another.

It would be nice to trade them in on the new one. I know they are not worth much to a retailer but they aren't worth much to me either right now. I was just thinking they might sell remanufactured ones.
