I have 3 1979 quarters. Two weigh 5.58 grams and this one weighs 5.75gm. I can find no info. explaining that. Could it be 40 % silver? If so it seems it would be valuable. Thanks for your help again. Jim Bee    |

@jb, first can you confirm that your balance is measuring other items accurately? Thx.

Yes, it is measuring properly. I have been weighing pennies,nickels and quarters for months now and it is always right on.

I also have about 50 quarters in front of me that I have weighed and this is the only one that is abnormal.

Ok good to know--better to know that the weight is real. This quarter seems to be a bit on the high side of mint tolerance, but that edge shot tells me that it is clad and not silver.

Would that hold true if it was 40% silver clad composition?
I wish I had a bicentennial quarter to look at the edge.

In order to be a 40% silver planchet, it would have to had been struck on half stock and in 1965-1967 or 1976 40% silver stock. That is too many years away from that event to even happen.

Well, That's a new one. My wife and I did the tissue test 8 times without knowing which 1979 quarter was was right or left and each time the darker one was the 5.56 gm coin. |

tissue test will show silver as lighter than a clad:  You need to have a silver coin to complete this test. One clad, one silver.

There's no chance it is 40% silver so you need not consider that. Weight Tolerance for modern clad U.S. quarter dollars is 5.44 grams to 5.90 grams. That is "as struck" from the mint(s). |
