I'd say MD as well.



to the CCF!

Slight Machine Doubling on the incuse devices makes them look larger on this design:

Note on the last image, the devices on a DDR that are incuse, are reduced in size. On the raised devices on a doubled die, the devices will be enlarged. So on your coin the MD is on the tops of the devices on the reverse. The images I posted show the MD in a different direction on that image. On your coin, probably the bottoms of the motto will show MD on them. The machine causes the Machine Doubling. On a doubled die, the devices are hub doubled on a doubled die. Thus on your coin the dies are not doubled, so the coin is a normal die example with Machine Doubling. (But Machine Doubling can happen on a doubled die, caused in the same manner as your coin. But because the die is normal, the MD added no premium for your coin.
