Note the distortion on the DDO on the 44 compared with a normal 1944 cent? Look at the centers of the devices, not on the outside/inside edges of the devices.

Note the reduction of the devices? Machine Doubling strikes again on this coin. (But still a doubled die with Machine Doubling) Circulation alteration and Machine Doubling never creates a doubled die.
