Note on all reverse images you will see the devices widened because of the heavy grease almost blocking out a lot of the devices. Each one that it is affected looks widened. That is what we would see on a stuck through grease error. The dies are tapered with the tops of the devices narrow and widened at the base. When the devices get blocked (at the tops) then just the lower part of the device is formed.

Possibly the the die was wiped with a cloth spreading the grease evenly in some devices, but yet leaving enough clearance to see some of the device on the coin. So it is a
Struck Through Grease error. Cudos to those who called it.
