Ok, so I read this whole post because I was certain I had the 1964 SMS JFK Half dollar until I saw this MM D on the back. So of course I was a little defeated at first but this coin is truly amazing. It has the satin finish, accented hair, the B die difference, the polish marks between the oF & AM and half and Of, the only issue is the tear drop below the 4 because of the redish tone and my magnifying glass is amateur rated. Please, if anyone could just take a look at it and let me know honestly what you think. Could it be a presentation coin? I'm posting images of coin now, but my phone takes terrible pics. So Sorry but hopefully you can give me a little insight to this. Oh, and it was given to me in a case. Its plastic but around it has cardboard casing saying John F. Kennedy 1917 1963 35th President
