I came across thisi 2015 penny with markings on the front of the coin. There appears to be a raised squiggly line that turns into a straight line that curves around the face to below the bust at the bottom. I was hoping someone may be able to help me identify if its an error or not. Thanks for your input.
It looks like some sort of discoloration, perhaps caused by another coin/cent. Either way I see no evidence of an error.
