It looks like the back has some type of wax or something on the back. It was in a Whitman Folder for LONG time.
A VF type of Obverse and a VG Reverse. Sort of makes it on the order of a F12 maybe. That Reverse is really poor though.
I was stuck between VF20 and F12. The reverse photo looks a little blurry. I'll vote VF20 and assume that a better photo would make it that grade.
I'd say overall a F 12 the obverse and reverse are quite different in grade as everyone here has laready stated.
