I haven’t got it graded yet with the error .. thinking of going to a a authorized PCGS dealer and getting it graded there..
What makes you see a doubled die, rather than a machine doubling? The widening of the lower digits is bidirectional. Have you compared yours to the diagnostic photos? The date is not the same. This is not a "analog" experience, it is binary. Either it matches the photos EXACTLY, or it ain't it.
It is hard o fully explain if one hasn't actually read about how the coin is made. Yours is mechanical doubling. The 1955/55 cent is one of the larger separated double die, that is why I am using it to illustrate. So the die for this coin was impressed ( squeezed) twice as was custom then , but the die alignment used to impress was slightly moved/rotated between the first and second squeeze and the second press's ( image) did not over lay the first, but they were squeezed with the same effort , so they are approx. the same height. You can see this by where the numerals overlap. This is a classic doubled die ( image) coin. Now if the dies used for a coin is aligned so one image should be produced, but the die is not firmly fixed in the press, it may rotate -jiggle a little as hitting the coin metal and produce an image that is usually one normal and a flattened or smear second image. This is Machine doubling and not a high valued coin. Many sellers on eBay do not know the difference. This photo is a 1970-S that suffered a mechanical stutter as it was striking the coin and produced the effect you see. This is what yours did , it slid a little to the top and produced the image you see, but it is flat compared to the primary image. You will find that Mechanical doubling, Die deterioration damage, and environmental damage ( smearing the relatively soft copper) are what we see the most as it is far more common. It takes years to understand all of the factors of varieties like this, so patience is needed . Best Luck Jim
