Hi Tommy.
Your Stylized Wagner smooth bottom, 10 skillet , would have been produced from 1933 thru 1959.
There are flat ones without warp out there.
The frustration that can occur, is when you know it is FLAT when you examine it, and then when you heat it up.... it becomes a spinner!
(doesn't happen often but it is a possibility!)
Blue Book values are less than what you gave.
The #10 is a more common size.
Hope that helps!
