Anyone want to take a crack at this? Other than the somewhat blurred stamp on the bottom, it's basically flawless. I'm thinking its possibly dating back into the 50's-60's, but I could be off a decade in either direction. The fact that it says "oven safe" and mentions noting about dishwashers and microwaves, leads me to think it may be older.

I would really like to get an idea of its value if anyone knew.

Thanks,
David
