Well, I just bought a #9 block epu nickel plated slick skillet, pn 710 with the low domed lid for $52.93 with fedex which is my all time high priced Griswold purchase , but before that the most I ever paid was $18 for a button logo high domed #8 skillet lid.
Knowing nothing, I sold the lid almost immediately for $36. I could have done better, surely. The panhandler is offering the identical lid for $100 or $125, best I can recall.
BTW, hello everyone. I'm a newbie to cast iron and am a small time flea market dealer, mostly of good no-name cast cookware which I strip and restore.
