Found this in change this evening and noticed the rim. The surfaces look grainy as well. What say you?

    Looks like it may have been either buried in an acidic environment such as the beach or it may have been used in gaming machines.

    Looks chemically treated. Maybe someone left it on a car battery.

    Acid causes this. It looks normal otherwise.

    Metal detector find---probably found at the beach.

    The edge has been 'machined' to
    give it that strange look on the
    reeded edge, in addition to
    the surfaces being altered.

    I've seen lots of reeded edge
    coins, from dimes to halves, with
    this altered edge type, and haven't
    figured out the purpose of it, or
    exactly how it was done.....

    However, without a doubt, it is an alteration;
    the coin itself is genuine.

    The core is copper while the outer clad layers are copper-nickel alloy. If this coin was exposed to an acidic or other corrosive enviornment, you would expect the copper core, being more reactive, to deteriorate or disolve at a faster rate than the copper-nickel clad layers. Hence, the copper core is recessed compared to the copper-nickel clad layers.

    just like your teeth corrode when you drink Mountain Dewimage

    sorry, couldnt help myself Mountain Dew - same thing happens to enamel - seen too many mouths with teeth that are eaten away by bacteria acting on the gobs of sugar in MD - very similiar to the above coin - add additional citric acid to the mix and you have one potent poison!!

    I, too, have seen numerous coins with the "machined" appearance. While I've
    yet to see one in a BU roll or bag, I've always suspected it was something done
    at the mint and during the strike.

    You're right, though, and I hadn't noticed it.

    Do you think it could be some sort of issue with the collar or the edge of the die?
    Perhaps they are simply damaged at the mint in some operation. I've seen exam-
    ples which appear to be virtually unc. These do appear machined but due to the
    large number and the improbabilty of anyone going to the effort, it's difficult to be-
    lieve it isn't part of some process.
