I just received a Griswold skillet. I'm sure what it is, the outside looks like chrome the bottom looks like a normal cast iron skillet and the inside is very black. On the bottom is a small Griswold logo, the number 6 above the logo and towards the bottom is either the number 699 or maybe 698. Can anyone tell me what it is, and is the inside a normal cast iron skillet. it seems so smooth I don't know what to make of it. I don't know if its something valuable or just ordinary. Almost forgot it does not say USA or anything like that on the bottom. Thanks
