Went on a road trip recently and found several pieces that do and may have value. Most are in the lye tank now but here are a couple pics of them fresh from the wild. The three orange looking skillets were found in Van Horn Texas. The Wagner Fat Free skillet and the BSR 3 S were found in Giddings Texas. The Danish Cake Pan (Griswold 962) and the camp fire skillet came from out of state. My total cost was under $100 not counting the gas/hotel/wear and tear on my truck etc. but it was a fun trip.
