I will guess a MS65 - don't really know anything about them. To get rid of the glare use a diffuser of some kind - paper towel, napkin, etc. See this thread by Paul.
You folks were very accurate. My thinking is that the distracting ding between the eye and ear is in a prime focal area, but the coin has good lustre and some nice eye appeal, so I guess they market graded it as MS-66. Thanks for guessing!
