As a collector of MS Washingtons (albeit a 3 year experience) I don't see this as an MS coin. In the first two photos I see too much wear\luster break on the obverse in Washington's hair and on the reverse in multiple places. I think with the post 64 clad coinage, you get more wear for your mileage, and so to me, the post 64 Washington's need to be in tip top shape to even make it into the MS grade range. The third pic does make the coin a bit more eye appealing, in fact in some ways it looks like a different coin, but I know it's not.
At most I see an AU53. to get to AU 55 or better I think you need to see more details in the wig on the obverse along with less dings and nicks on both sides.
