Thanks for the quick response. Before I started this thread I did some internet searching for plated Piqua and came up empty. The one that I saw today was in a showcase next to another small Piqua and I could only see the bottoms of them. The second one said "Favorite Piqua" @ 12 o'clock, had a heat ring, but no size designation. I believe that one to be considered a toy or salesman's sample.
The one that caught my eye said "Favorite Piqua Ware" @ 12 o'clock with a clear numeral 1 @ 6 o'clock, had nice plating and a heat ring on it. Would this one be considered a skillet with some collector value, or just another toy?
They were asking $65 for it so I had to step back and try to educate myself before doing anything stupid.
