I think the scratches are the distractors, and not from bag marks, so it knocks it down. The wear is minimal on the obverse as it has a weak strike, but not showing much wear from circulation. The most likely places on the reverse are also showing marks and scratches, with the middle ribbon (most commonly worn as the highest point) possibly a weak strike, but more likely from circulation wear. I'm just guessing, but I'd say it might reach AU55.
