I would give it a 63. I think there is just a little too much chatter on the obverse to get higher.The hits in the sun and rays area might hold it back from a 64 , coupled with the planchet scratches down the middle, and what looks like a couple small hits on her outstretched arm. A nicely struck coin , with a nice thumb and almost all the feathers on the eagles leg. Great looking Walker, I love them- My Walkers remain right now as the only complete set (Date and MM) I own.
