Griswold's Erie #7 70/B

Picked this up at a flea market today.

Don't have my books in front of me, but I'm pretty sure that's 701B. Nice skillet!

I can hardly find any information about it other than the dates in which it was made. I cannot find any that sold on eBay. Having a hard time finding a value on this piece. No chips no wobble no spinning. It's in excellent condition.
