Hi everyone, I'm new to this site and I can't say that I know much about coins, but I love casually collecting wheat pennies (as a cashier I would take the few I found each day). With some research in mind, I always kept an eye out for irregularities. Recently I came across a 1928 Philadelphia penny with a strange detail near the top of Lincoln's hair. It is a curved line that looks at first like a scratch but is actually embossed. Is it possible that this is an error from the striking? My other guess is that at some point in its life, something with a strong edge hit it with enough force to push the metal on its surface upwards. Although, it seems as though the details on either side of the ridge are untouched. I hope this isn't too ridiculous of a question, thanks for your time! K.J.
