Machine Doubling, a worthless type of doubling.
Also a DDR is a variety, not an error.

On the EPU area, these devices are incuse. When a doubled die happens on this area, the devices are reduced in size:

On Machine Doubling, these devices can also be taller than normal:

On Machine Doubling also the Opposite side of the devices can can be affected on the raised and incuse devices on the same coin:

Funny how these devices are altered on Machine Doubling on both the raised and incuse devices differently.
