coop Bedrock of the Community United States 62064 Posts	Posted 02/09/2017 12:09 am A doubled die is caused when the hubbin of the shows a spread between the hubbing. Making the devices wider/taller. The doubling is on the die, thus the term Doubled Die. On Machine Doubling, the devices normal dies are damaged after the coin is struck it reduces the size of the devices. while they may look interesting, they are not doubled dies. It is cause by the machine, not because the die was doubled. But you can have Machine Doubling on a doubled die as well. But on this example it is from a normal die. Report this Post to the Staff
