When the date and the mintmark have doubling in the same direction it is for sure
Machine Doubling. The hubbing of the die and the addition of the mint mark are done in two separate processes. So the result is always
Machine Doubling. There can be a doubled die and a RPM on a coin, but the direction would be in different directions. Also this is called push
Machine Doubling as the metal was moved larger than the original strike. (Still no premium for this to a serious variety collector)
Machine Doubling is not from a doubled die, by caused after the strike and is common to find.
