There’s not enough luster for a 55, but not enough wear for a 53. Hmmm... I’ll go with AU-53 with a possible bump to 55
AU-53 here as well. AU grades are only about wear and not contact marks. So the hits you refer to will not affect the outcome of the grade. If this coin was UNC then the contact marks are considered. This is why you can have very clean and gorgeous AU-58's alongside baggy and beat up AU-58's.
To me it looks like a weak AU, or what some dealers used to call XF48; really too much wear on the curls for any AU grade. But considering how nice it looks, wouldn’t surprise me to see 53 or even 55!
