Value of a Pennsylvania Lawn Mower?

I have a Pennsylvania lawn mower edger/push lawn mower that is at least 60 years old. I am wondering if it has any value. The lawn mower part is about 6 inches wide and has a round cutting disc on the top side for edging. The disc rotates for edging along sidewalks, driveways, etc.

Any help you can give me will be much appreciated.
Thank you.
