Since we can't see luster well in photos, just going by the high point rub I'll say 58. very attractive toning.
Personally I think this coin is AU55. Not much wear on the high points, but the luster is muted by the thick toning. Here's the grade NGC gave it!
Looks better then a 53 ngc real strict tho. Sometimes lately I think their tougher then Doug maybe he's working for them now lol
