That's a genuine clip! The "damage" that you see opposite of the clip is the Blakesley effect. When the blank goes through the upset mill, the absence of metal at the clip prevents the application of pressure which forms the rims on the opposite side of the clip.
Your clip is not a curved clip, but was likely produced from the edge of a copper cent strip.
