Welcome to Numista. I can't tell you exactly what it is but it is definitely not a wrong planchet, only resembles a U.S. Cent and is most certainly not a genuine U.S. cent. Perhaps a magicians prop?
The coin was shrunk with a (very) high voltage electric shock, it is even visible were it was held during the operation. More examples of shrunken coins here:

Both threads have a link to an external site describing how it is done.
I don't think so. How do you explain absolutely no legend and lack of fine details unlike the coins on the links you provided which are smaller but show all the original legend and details of a authentic coin?
Harry is right. The coin is not one of those shrunken coins. Actually the details are not smaller at all. Both color lines in this picture are the same length.
What you have is a real penny being worn away by rotational movement against a surface (same or similar to washing machine coin). Note the folding over of thin displaced material at the edge. Compare to this example: https://en.numista.com/forum/topic28647-5.html#p1190116

After closer examination, I agree with rsirian1 and harryg that it can't be a shrunken coin. All remaining details have the original size, it is just the edge looks as if it was pressed inward.
