Early Bday Present 1971-S Ike Silver

So my 21st birthday is Tuesday and the parents came over to spend time with me. My mom got this from an antique store and was like sorry its not more I am ashamed about how much your 21st birthday gift is, I wanted to get you something nice. I was like its fine (its my first silver Ike) so I think it is really neat. I was like oh you probably gave $20-$25 for it. She was like no I only gave $5. I was like holy cow do they have more, but she doesn't now. It is in mint celo. I am tempted to open it up and put in my 7070, but it is in the safe at my parents house. I live in an apartment and don't keep my expensive things here. I am not good at grading, but due to the hit on the eagle's neck and the little nick on his chin I think it is probably ms65. Sorry for the bad pics through the mint celo. The only contact I see are the spot on the chin (circled in first pic) and the spot on the eagle's neck. The rest is the celo. What grade do you think it is?
