The passenger cars are very hard to find, and those are pretty nice. They are also very desirable to UA collectors.
My question to you regarding value is are you a buyer or a seller?
If you’re a buyer, $100 each is a bargain.
If your a seller, start at $500 for the pair and work your way down. Also if I was selling, I’d look for the loco & tender to complete the set. Complete sets seem to bring stronger prices.
