No it isn't sms special mint sets were from 1965 to 67 your Kennedy looks normal to me and in that condition melt,still silver is silver.
From the Redbook... 1964 Special Strikes In addition to the normal SMS coins dated 1965– 1967, there are other, very similar pieces dated 1964. These coins are unlike ordinary Uncirculated and Proof coins made that year and have characteristics akin to the SMS pieces. Collectors generally refer to the 1964 pieces as Special Strikes. All denominations are very rare, whether sold as single pieces or in sets. It is unknown why these pieces are rare (whether sold as single pieces or in sets), why they were made, or how they left the Mint. Yeoman, R.S..

I guess I was wishful thinking.the color looked off and the design was sharper plus I'm just getting in to coin collecting so I am very ignorant about coins still.thank you for the help!
I don't really see any "sharper" details based on photo and looking at/studying Kennedys for nearly 60 years...looks regular/normal to me plus the special '64 SMS pieces are so rare that it would be very unlikely.
