Both date and MM seems to be machine damage in this case.
Wanted to mention machine damage and or
Die Deterioration does not discriminate and can be present on a true doubled die or RPM.
I would like to add that 99% of the time, strike damage showing in the same direction on the date and a hand punched MM is a good indicator its not true hub doubling or RPM. I like to leave at least one percent open to the possibility the combination of events can be present. Thanks, Doug.
