The coin star machine kept rejecting it so I thought maybe I better keep it and ask.

    No -

    It has badly damaged/corroded surfaces

    Not an error coin of any kind, I'm sorry to say.

    Thank you Sir, I haven’t yet studied these. What are the characteristics in determining whether or not you have one if you don’t mind me asking?

    Well, that's what I thought then I got snared by the corrosion. I try not to ask stupid questions but I have no clue on the annealed planchets. I can now deduce that there is no corrosion typically associated with these and that I'm just looking for a clean off color surface.

    I'm assuming you have already done this but just for the heck of it, can we see the edge of the coin and ask how much it weighs?

    Sure, but it’s still at the office so I’ll do that and get back this weekend.

    The reason I was asking, I heard or read somewhere that some (not sure what years), of those quarters may have been struck on foreign planchets. A few years ago, a guy at work (a non-collector) brought in a quarter to show us. It was very light in hand. It looked a sounded like aluminum. Couldn't see any copper clad.

    I offered to buy it off him but he wasn't interested. I told him he should have it attributed by a TPG'er or take it to a coin dealer, but he didn't seem interested. I lost touch with the guy. Never knew what became of him or the coin!?

    @USSID17 I hate when that happens. This one felt like the normal weight but I'll check it and get back.

    Here is one I found that I believe to be an improperly annealed planchet.
    You can see the difference in color, surfaces & the edge ...... hope it helps. ;)

    Severe corrosion and damaged quarter. @ifthevamzarockin... That looks like heat oxidation damage.... Annealing is done with nitrogen and hydrogen, so oxidation unlikely. JMO Cheers, RickO

    Not sure what it is. I found several in a solid, sealed uncirculated box, they stood out like a sore thumb. Maybe I should try to get some better photos and start a thread.

    Edited to add: All of theses came out of the same box.
