The easiest way to test for missing clad (if the coin isn't clean) is to take the mass. A standard clad quarter is 5.67g. The cupro-nickel clad layers are about 1g each (2g total). So a quarter missing a single clad layer will be about 4.67g, give or take.
It seems pretty unlikely that a quarter would be missing both clad layers (although anything is possible, I suppose). Your quarter looks like it suffered some heavy environmental staining. I have nickels that have turned a red color from getting buried or exposed to a somewhat acidic environment (like salt water). A nickel is 75% copper, 25% nickel, which is the same metal composition as the silver-colored surface metal on a clad quarter.

extreme staining, I can see a bit of the cladding over the tree on the reverse, But can we get a weight of this coin? If the cladding is truly missing, it will weigh light. |

An accurate weight--to two decimal places--would be welcome.

Could also put it between two good quarters, because it should be visibly thinner.

Thanks to all those who responded. I should have thought to weigh it sooner. It weighs 5.68 grams. I'm now in agreement that it's just an environmentally damaged quarter.

to the CFF! It is possible to have a coin struck on just the copper core, but it's really, really rare. Only a few coins missing both clad layers have ever been certified. I started to write more on the subject, but as I was checking my facts, I found this article from PCGS. https://www.PCGS.com/news/missing-c...-error-coins . It explains Dual, Single and Partial missing clad layers and does a much better job than anything I could write on my own. ANA ID: 3203813 - CONECA ID: N-5637 Clean a coin that may be worth collecting? Please DON'T! When in doubt, leave it dirty!!

oznog, I agree with environmental damage. Just a note: when weighing coins do not forget to factor in mint tolerance. http://goccf.com/t/407956John1  |
