    Everyone,

    I found a black quarter a while ago, and found this black quarter. I have read about annealed planchets, but I also know that coins left outside can also turn black. I would appreciate any help with this as I'm not sure either way to know the difference.

    Thanks,

    Swerths

    I thought Black Quarter was a disease ? LOL

    It looks like environmental staining and toning.

    Bleach turns silver black.

    This quarter is clad, no silver. Most likely Nickel (III) oxide from environmental action.
