It's a man-made novelty item. Drop it on any hard surface, and you'll hear a different sound than if you dropped a regular cent. It will have a 'thud' sound, compared to a normal US Cent.
A seam, but it also was most likely milled out then another side of a cent placed into it. Thanks, Jacob
To me... it looks as if there was an adhesive, like glue or something.. causing it to stick with another penny .. for a long time? Because those grooves of the house are there... right across his face.
