onebakedpotato New Member United States 8 Posts	Posted 09/24/2020 6:59 pm I would like to get more sets of eyes on this Lincoln Cent I found recently. I am not sure about the difference between Machine Doubling and double dies. I was hoping you could help me to know what I found here. This may be my first significant Lincoln Memorial cent find.

Spence Moderator United States 34423 Posts	Posted 09/24/2020 9:17 pm @1bp, first welcome to CCF. Second, yes shelf-like doubling that reduces the width of devices is going to be MD.

SensibleSal66 Valued Member United States 79 Posts	Posted 09/26/2020 03:52 am Machine Doubling creates this "shelf-like " appearance lower than the actual devices. Where a double die is that the "Die " is made doubled and strikes the blank coin appearing as an equal height on device and numbers > Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 09/27/2020 3:06 pm Note all the affected areas are in the same direction, because the machine was loose and damaged them in the same direction on that strike. On the next strike they could be in a different direction/angle/strength. It just depends on how the machine feels on each strike. They are not doubled dies, but a normal die with machine damaging the devices after the strike. This can also happen on doubled dies, altering the DD but in a songe direction: Note on all 4 images they are 1969-S DDO-001. Then note the yellow arrows. They point to the affected areas of Machine Doubling, on a doubled die. Again note, that all the affected areas are in one direction. The doubled dies are cause by doubling on the dies, thus the term "doubled die". Report this Post to the Staff
