Thanks again everyone!
Chuck and CS, thanks for the explanation as to causation and probable methodology giving the result we see. Having the understanding of how events occur is very helpful and aids in seeing the suspect coin in a totally new light.
wz - what they're saying and I agree is something struck (the coin took a hit) this coin right near the bottom left of the vertical bar of the mint mark causing it to shift/move right. The vertical bar became repositioned to where we see it now giving it the current appearance.
