I bought 3 rolls of half's today just for the heck of it. I was amazed when the first roll show this silver bicentennial proof which I believe to also be a DD. What you think?
You sure its silver?they also made clad proofs. http://varietyvista.com/12 Kennedy Halves/DDOs 1976-S.htm http://varietyvista.com/12 Kennedy Halves/DDRs 1976-S.htm
I see an anomaly but no DD in my opinion, still a nice find. Keep searching those coin rolls you never know what you will come up with, good luck. Thanks for sharing.
That wouldn't make a differencedid you forget only the 1964's were 90% silver,only the weight can tell.
Without seeing the edge, I was guessing clad proof which is a lower mintage, 7M, than the silver proof, 11M. Nice find on the S proof. And 40% silver halves have a completely whitish edge with no copper showing. I think the core is alloyed. So it is "grayish white".
I certainly have not forgotten that a Bicentennial CLAD Proof will show in its’ edge. I was responding to the OP Kennedy, not before 1971.
