Louis. I live about 5 minutes from Boyertown PA which is one of the places that they were made. I work with a guy who worked on the molding floor for 35 years. 35 years of pounding sand. That's a long time. Anyway, He say that they made a bunch of sizes. Like Will says, I have yet to see other than the #5. Very strange since I live so close. Will has the value correct also. Even though they are a local piece here, they still don't bring that much. Alot of local antique / vintage things around here, bring top dollar, and well beyond. I once saw a local collector buy several local milk bottles for $600+ a piece. :o :o :o But these skillets just don't have the same value, and I have no idea why.
