jbuck Moderator United States 188342 Posts	Posted 05/18/2011 11:41 am I would need to see the coin in hand to be certain, but my guess is that it has been plated. There is a copper band on the 40% silver dollars, but it may or may not be perceptible for different reasons. A plated coin should have no visible copper band unless the plating was wearing thin.

Conder101 Bedrock of the Community United States 17884 Posts	Posted 05/18/2011 12:43 pm If you really can't tell, then a specific gravity test should be the final test. The coppernickel clad pieces would be 8.92 and the 40% silver would be 9.53 Report this Post to the Staff

Mach1 Valued Member United States 301 Posts	Posted 05/18/2011 11:09 pm Looks like a '72-D to me. It's clad, not silver. It would need to be an '72-S to have any silver, and then it's 40% silver....not 90%. Report this Post to the Staff
jbuck Moderator United States 188342 Posts	Posted 05/19/2011 11:33 am After seeing the new photos, I say it is most definitely a plated coin. Coin Collector Since 1978 Avatar Old Avatar 7070 Eisenhower Australia Canada World CCF Members on eBay CCF eBay Search Engine Report this Post to the Staff

Las_Vegas_Larry Pillar of the Community United States 817 Posts	Posted 05/20/2011 08:01 am jbuck in a silver clad IKE does the copper look different than in the nickel copper clad IKE? Mach1 yes and it shows bright. If it's not silver clad it has been plated. Thanks guys Report this Post to the Staff
Mach1 Valued Member United States 301 Posts	Posted 05/20/2011 10:39 am Hmm, interesting. I guess a tissue test would show bright weather the coin is 40% or just plated. An Eddy Current test would be the way to know what alloy content you have for sure. An Eddy Current test is also 100% non-destructive. Do you know anyone who works in the Non-Destructive Testing (NDT) industry that could help you out? Report this Post to the Staff

Yes, because the copper core on a 40% silver coin is actually 79% copper and 21% silver. The brown will look more gray than red. Quote: Hmm, interesting. I guess a tissue test would show bright weather the coin is 40% or just plated. Correct, because the outer layers are actually 80% silver; close enough to 90% to appear similar.
