I have to disagree. It looks more like two coin stacked between two boards and hit with a hammer. The transferred date area is the target area. If this were done with a vise and two coins all the devices would have been transferred:

This one was done with three coins. It shows two heads transferred onto the reverse. Note all the devices are showing mirrored.
