And
Machine Doubling. If it were a doubled die, then the centers of the devices would be enlarged:

The direction of die wear would be towards the direction of the closest rim.
Machine Doubling would affect the same sides of the devices on just one side. On a doubled die, the spread would be noticed on the center areas of the devices. Not a doubled die.
click on image to enlarge to see the spread better on the image I posted!
