Being as these were notorious for weak strikes, I was going to throw out AU-53 since it looks like there's just a touch of wear on the hair detail, top of the wing and head. While not familiar with PCI I would say they were close. The top two might cross grade it a point or two lower should you opt for such. As for being cleaned? The hint of original mint luster and general surface looks about right for a silver coin improperly stored. All in all, a very pleasing example of the series sleeper. Nice pickup!
