I picked up $7 of KHD from the bank and the 1979 weights 11.45. Since the clad weights 11.34 would it be possible that this may be a silver clad?

Try the tissue test and find out what the mints tolerance is would be my suggestions. John1  |

John, I can't find anything about a 1979. I did find a Coin World article about a 1971 that said The coin's specific gravity is 9.5, close to the standard 9.53 for silver-copper clad, with a weight of 11.44 grams, within tolerance of the U.S. Mint standard 11.5-gram planchet. I did do the tissue test...it's the one in the middle   |

I have several from roll searching a ton of halves that sounded different when dropped onto a glass surface and also were lighter in weight. Every once in awhile someone posts these. Sorry I do not remember the forum consensus them. But I think mine were 79s also - sorry I cannot get to them at present to verify that though.

Do you have a 40% to look at and compare? Looking at your photos it looks clad to me not silver. John1 Edited by John1

You have to put a silver coin in there to see if another silver coin is present.  Edited by coop

I know this is an old post...but just in Thursday received a silver coin in change. Here is my tissue test...do you think the KHD is silver?   Edited by rocktowngal

Depends on what year it is. Make sure to use a single ply of tissue. (Most are two plys, you just have to remove one layer)

Coop, the KHD is a 1979 and the silver I have in there with it is 1964 quarter. It is a single ply. Before I didn't have any silver to add in there. Thanks.

Also this wont work on toned/dark coins. But they must be fresh looking coins.

Thanks Coop, trying to figure out the best way to go about finding if this is 40% silver as it is 11 grams overweight.

Tolerance on a clad half is .454 grams +/- so a perfectly normal clad half can weigh as much as 11.8 grams, well more than yours does. Weight cannot be used to tell a copper nickel clad coin from a 40% silver one. The Weight Tolerances overlap WAY too much. A coin that weighs anywhere from 11.1 grams to 11.8 grams could be either one. You will notice the spec weight of both coins lay within that range. |
