Accented hair?

This afternoon I checked out a flea market and a vendor had silver half dollars in a tray for 12 dollars each. I took the last 3 they had. When I got home I took a closer look at this coin and I think it is a accented hair proof. If it is, just out of curiosity, what kind of value does this coin have in its condition? I am new to the hobby so any help would be appreciated. Thank you
