I'm not very familiar with electroplating, but perhaps it is a trick coin that has been heated. It appears as though it may have been in a fire or heated with a torch.

Definitely a fake you can see the smooth surface on the bottom layer which indicates its the obv of the coin....and the thickness is the most prevalent to me huge difference in size lamination never occurs with a coin split in two...heat treated, as seen by the smoke marks and one has been cut in half and placed on the original. Normally good fakes they cut the coin directly in half but the thickness is all wrong even for begginer could counter fitters...

Yes, clad clamshell separations can occur naturally just as a coin can completely lose a clad layer. Clamshells can be hard errors to find because they tend to break off due to handling or because of some hamfisted simpleton prying on it with a screw driver However, this coin is not one of those clamshell errors. High heat will also cause the separation of clad layers, sometimes manifested strictly as an internal separation that looks like a bubble or a clamshell separation such as your coin or this one.

I disagree.....the other looks like a fake also and both are un-certified...weight should be determined and the center of coin is suppose to be copper which would make it sandwiched with the outer layers being white.....according to pics this is not the case.

That was the whole point of my post- the bubble and clamshell I linked were heat-treated, i.e. nothing but damaged coins, just like the coin that is the subject of this thread. If you are saying the dime missing a clad layer is fake, then you are wrong as that coin is in my personal error collection.

Not saying that at all....sry for mis-interpretation...i have seen a few coins missing a layer but none split...that would be easily identified during minting

Why don't people educate themselves when attempting to buy these things! Someone payed 16 dollars plus shipping for a damaged, clad kennedy.
