Hello guys I have this 1987 Washington quarter that appears to be missing clad on both sides or possibly improperly annealed. It could also be damaged but it only weights 5.27g. What do you guys think? (thinner planchet as well)   Edited by JJC314

@jj, I would start with the hypothesis that the color is due to environmental/chemical toning and the lower weight due to lost mass from circulation.

Yes well let's see what others think. I can see the cladding where that surface toning has been scratched away so I don't think that it is light due to that.

Thanks Spence, I also notied something that caught my attencion. Usualy I, ve only seen this in Lincoln Cents. The dark spots close to the forehead and nose as well as aroud United States of America seem to be due to copper oxidation. Is this common on damaged coins as well?

That carbon spotting you see can happen on any coin that has copper content in it.
I think that the coloring you see is due to environmental toning. I can see the silver cladding showing through the dark toning on the devices, field where it was rubbed or scratched, and especially around the rim.

Environmental tarnishing/toning/discolouration post mint damage. May have been chemically altered by being buried in soil. Possibly a metal detector find? No premium, just damage.  |

Note the coin has a coating on it? When it wears off, the coin, the normal color is under the coating. Normal coin found by a metal detector. Spender.

Depending on the Soil. If the soil is acid, then it can leech away some of the metal. But mostly your coin is turned from being out in the wild for a time. In circulation the color will slowly appear on the highest devices first and lastly on the fields.    Just a spendable coin. |

Ni(PΦ3)2(SCN)2 will be : red sq. planar (activation) with: μ =0 BM
The coins like this are exposed to an alkaline salt.
I saw more and more coming on the market.
Conclusion: It is not environment but an human action.
