1937-P Lincoln, Please Help W/ Grade Opinions

i am only confident in my grading skills, within a range. I am fairly sure this coin grades XF or higher. I am undecided if it
could hit the AU range. the mark above the "T" in liberty is a fairly deep contact mark, or a scratch. there is wear evident only on the ear, beard and cheek. there is some nice mint luster. on the rev. there is some "organic" gunk around the "S" in pluribus, otherwise guite clean. this image is a scan - not a pohotgraph. opinions are appreciated. thanks.
