Hello all. After a long night of sorting pennies I have gotten around to examining a few carefully and I have discovered this peculiar variety on a 2003 vintage. It appears there is a ghosted "E" on the reverse, between the "T" and the "E" in "UNITED". It is a small "E," roughly consistent in size with the "E" in "WE" on the obverse, at exactly the same distance from the rim. Here is an image: Excuse the poor quality. My camera mount is a bit dated. There is a clear impression there of an "E." As they say, multiple straight lines like that don't appear naturally in nature, and I doubt it's post mint damage. This variety is not in my Rich from Pocket Change guide, nor is it mentioned anywhere in my Google searches. What type of error is this? Is it known? Thanks in advance.
