Junior e there is Copper in the core. Good eye.
Does that mean it was plated?
Was this much ado about nothing?

Not nessesarily, there are well over a dozen known specimens each of 1977d and 1974d ikes struck in 40% silver. If it is struck in silver it likely is on a 40% planchet rather than a 90% planchet. I personally would be willing to risk the $15 or so and send it of to anacs for verification, but thats up to you. Since there were 40% ikes struck in 72, in theory it is possible that one was struck at the denver mint since they were in other years.

The ANACS census lists one specimen of this issue struck on a foreign planchet, so offmetal strikes are definitively known for this issue. -XoG

XavierOfGreen thanks for the info, I will check it out.
Darth Anarchus sometimes you take a chance, some times you loose a lot, this time even if its plated its only $24.

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.

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

Here are some views of the edge that might shed some light. Shows copper.  More copper spots?

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%.

After seeing the new photos, I say it is most definitely a plated coin.

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

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?

Quote: jbuck in a silver clad IKE does the copper look different than in the nickel copper clad IKE? 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.

I am no expert but as soon as I saw the pic I thought "plated".
