Yep. It looks like Machine Doubling. The doubled area is flat and step-like. It also reduces the size of the effected letter, number or design element. It happens when the coin is struck and the die then "bounces" on the freshly struck image, cutting into them slightly. It's caused by loose dies on the coining press. No extra value.
