ghostrider Pillar of the Community United States 1116 Posts	Posted 05/17/2012 5:20 pm I was searching some half dollar rolls when I came accross this 1776 - 1976 s coin. When I look at the coin's edge there appears to be none of the usual clad markings. I believe that the coin is 40% silver but have no idea as to how a person can tell. So the question that I have is: Does a 40% silver coin show any clad markings when you are looking at the coin's edge? I have no 40% coins that I can look at to make a determination for myself.

ghostrider Pillar of the Community United States 1116 Posts	Posted 05/17/2012 5:42 pm John1: According to my poor scale the coin weighs in at 11.5 grams. I also weighed a 1964 on my scale and it came in at 12.5. Whereas a 1973d weighed 11.3. So I am very happy to find a 1776 - 1976s 40% coin in circulation. Thanks for the help. Now I have to go back and check out my other bicentennial halves that I got today to see if I've missed something. Edited by ghostrider 05/17/2012 5:49 pm Report this Post to the Staff
biokemist6 Bedrock of the Community United States 12437 Posts	Posted 05/17/2012 6:22 pm 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. Report this Post to the Staff

ghostrider Pillar of the Community United States 1116 Posts	Posted 05/17/2012 8:01 pm 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. Regards......... Report this Post to the Staff
John1 Moderator United States 56855 Posts	Posted 05/18/2012 05:57 am You are very welcome. Just a note, just because you find a coin in circulation does not mean it can't grade BU. A BU coin grades in at MS-60. If you post a high rez photo obverse and reverse someone here can grade it for you just so you know what grade your coin is. John1 Report this Post to the Staff
