No, that's just heavy damage. The biggest clue that the circular impression area is damage is that the area opposite on the reverse is flattened. If this happened while it was in the dies this wouldn't happen.
Definitely Damaged. Looks like what would happen if someone used as a screwdriver. Just a strange theory.
More Denver Mint garbage - I hate when they put out trash like this! Seriously, I would like to see more pics, preferably with an electron microscope. Since you already stated it is an "error", what kind of "error" would you propose this is??
@Alexander Garcia That's what I call DEFDAM - Definitely Damaged. That alteration occured after it left US Mint. Not a mint error of any kind unfortunately. Welcome to Cointalk
