It maybe a bit of MD on that area. I see a bit of it also on 'G' of GOD also. Could have also made the contact on the ear lobe.
Machine Doubling can happen on one device, different from one device to the next, appear on one side, two sides or more sides of devices. There are no rules for them. The only is that is always reduces/pushes the devices after the strike, altering them. Usually appear on the edges of the devices. Can be soft or strong. It just depends on how sloppy the machine is when your coin was struck.
