1976s Kennedy Half Dollar

Weight it. 40% = 11.5grams. 90% + 12.5grams.

If it is an S-mint business strike, then there is no other option besides 40% silver clad. If it is a proof, weight alone cannot be used because the tolerances overlap for CuNi clad planchets and silver clad planchets. If it is a proof, you will also need to perform the tissue test to determine whether it is truly 40% silver or CuNi clad.

biokemist6 & John1: Thanks for the information regarding the tisssue test. I compared my bicentennial coin to a 1972 clad half and when tested by the sacrificial tissue (of the toilet variety) the bicentennial coin was noticably lighter than the '72 coin. So I believe that with your help that the bicentennial coin is silver.

So then I was curious and went to look at my Kennedy Dansco album and I noticed that there are three holes for the bicentennial S coin: A S proof, a S 40% BU, and a S 40% Proof.

So I now believe that by virtue of your help definitively I have a 1976 S 40% BU coin as proven by weight and tissue test. However, because it was found in circulation () I don't think that it can truely be called BU, but it is truely and definitively 40% silver.

So to each of you I say thank you and hope that I can be of service to you in the future.

Congrats on the awesome find in circulation.

How does it look? Check the high points for any wear to determine if it is BU or not.
