I feel it is
Machine Doubling. Not
Die Deterioration.
Die Deterioration on the single squeeze cents usually shows on the fields next to the devices in the closest direction of the rim:

The older style multi hubbed coins in the past show die wear from the edge of the devices towards to the rim:
Machine Doubling happens on the devices on either side of the devices. Top or bottom, inside or outside of devices, sometimes on two or more sides.

It always leaves flattened devices. Even happens on doubled dies:
Die Deterioration leaves a raised area next to the devices.

Hope this helps. If not, ask another question. I've got thousands of images to draw on.
