Mark,
Last year a big collector of chrome piece put several sets of skillets on ebay (each piece in a separate auction). Some of the pieces were near mint and, I think, some even had the labels in them. Surprisingly, they didn't bring all that much. Perhaps too many of them on at one time? I'd say your pan would be worth around what a very nice black iron one would be worth. Others have any differing opinions? I'm not to great on prices since they can vary so much. Plated pieces generally bring maybe 1/3 less than black iron but, when you have a super nice piece the price goes up quite a bit. Put it on ebay and you will see what it is worth on the day you sell it but don't be surprised if the price is lower than what you thought it would be worth. Or, it might bring more. Such is the world of collecting.
