I have searched through quite a few quarters now. I have observed a fair amount of the 2005 D Oregon 25c coins. I have not seen anything like this before. It doesn't quite match up to any of the known DDRs for this coin. If I had to choose one then I'd say it is closest to the DDR-006. Not sure and more than likely not a DDR at all. Just have not seen anything like it yet. What say you?
I first saw it with the minimum setting of magnification. Only magnified it more as I compared it to the magnified pictures on the error sites.
