It is all
Machine Doubling. It happens on the edges of the devices. Note on the opposite edge of where you are looking. Do you see the normal contour of that device. That is what that side looked like after the strike. But the machine damaged it and most of the rest of the devices after the strike. The area you looking at is where the device was. The device took a hit above that area. Look at the bottom loop of the 'C'. The side facing the rim is showing contour, the area opposite is showing the reduction of the device by whacking the devices after the strike.
Machine Doubling can happen at any level of the device. Even halfway up from the bottom of the devices:

Note on this image the opposite side of where the MD is, the contour of the devices are normal, untouched by the machine. So the coin was normal, it was just damaged by the machine after the strike. Always reducing the normal size of the devices.
Now go back to the area I mention on the bottom of the 'C'. Do you see where it was reduced. The line there was damaged, pushing the metal aside. Contour on the side face the rim. Missing now on the other side because of Machine doubling/damaged.

What would a doubled die look like compared with a normal coin this year?
