Coin and Paper Money Collecting/1980 Quarter sounds different and weighs less.



So I have a 1980 quarter. I've collected coins enough to know if there is an odd sound in the change I receive from the grocery store, whether it's a silver coin or something else.

Well this is something else. This 1980 quarter sounds odd. I have a little coin scale, so I weighed it. My scale says 5.5 grams, compared to the 5.67 grams it's supposed to be.

I would assume the proportions of the metal content are off on this planchet (though I'll let you decide), but would it be enough to add value to a coin? Or is this not anything special at all?



What is the thickness? Is there a clad layer evident in the center? I need more info.

---------- FOLLOW-UP ----------

QUESTION: Using a pair of calipers from work I just measured the quarter. It's .956in in diameter and .0656in in thickness. After measuring another 10 or so quarters it doesn't seem to abnormal, though they all vary a bit.

Beyond the weight difference and odd sound, everything else appears normal. There's clad on the edge, but not in the center of the coin.


Reeding apparent? Weight not that far off. If a dull sound, could be counterfeit. Don't think it to be valuable.

Sometimes you can think you have a real error coin. Here are examples of coins either being altered or damaged.

If you live close to a local shop, they should offer an opinion as to it's value and if it is authentic at no charge. Always try and get at least two opinions and try and deal with PNG dealers if possible. Here's a link to find one in your area:
