contact mark/bag mark/hit - normal circulation marks for a circulated coin. There is no error on that coin, sorry
Left of Y and the middle of Y where it splits doesn't look like bag marks. It is square and moves right across the V portion of the Y. I am not talking about the other small marks on the coin. Only what's under the Y. I understand that there are a lot of marks on the coin from the hundred years of circulation. On the reverse, at the top of the "C" in cent is an impression from the anomaly under the Y in liberty. I'm just pointing out what I see.
It's a circulation mark and not even close to a dropped letter. It may be a small chip but it's not what you think it is or what you want it to be.
Some dropped letters are retained and therefore not incused. This one is trapped under the Y and is partially retained, right side of the Y fell out but has a faint incused impression. Here are some reverse shots of the area opposite the Y in liberty. This is the impression made on the reverse by the anomaly under the Y. Die chips doesn't leave impressions on the opposite side of the coin.
A dropped letter that is retained would be flush with the surface, neither raised or incuse and it would not be made of metal so it would not have similar coloring to that of the surrounding metal.
@Avery G. This is the exact size of a C from cent. Notice that the C is incuse. A strike through like this does not damage the die it leaves an impression on the struck coin.
