I don't know if this is a known error, but I assume it is, only because I can't find any information on it anywhere. It is a 2000-P Lincoln cent, and there is very clear doubling on the reverse on UNITED STATES of AMERICA, and nowhere else. Is this a known error that I'm just having trouble tracking down, or should I submit it for certification, and how would I go about that? I will upload the best picture I can get shortly so everyone can see, but it's not my imagination, everyone I've shown it to sees it clearly as well with a jewelers magnifier with LED light, I just don't know how well it will transfer in a photo but I will see.
I've tried getting decent pictures, but of course it doesn't show worth a damn. I know there are all sorts of types of doubling, but I'm pretty sure it isn't machine doubling, because there is no flattening at all on it.
I did the best I could do, but it's a lot more pronounced than it looks in this pic. THere is a thin edge to the NW on every letter in united states of america, but bad flash and bad cam make it hard to show up. I circled the parts you can see with this pic.
I highly doubt that this coin is a doubled die coin. If it was a doubled die the smaller letters like the FG designers initals and E PLURIBUS UNUM would show the doubling better than the bigger size letters.a good thing to remember is that when a few letters are doubled on the edge of a coin they all should have the same amount of doubling present if they were struck by a coin die that had the doubling on it.
Since the dies were made with the single squeeze method, most of the DD of this era , the doubling occurs more in the center area of the coin. It doesn't look like a DD.
