Titles are Important! * Good day as the Memorial Day Weekend begins. I have tried to figure out this MM and I think it is likely machine generated in some way. Maybe a single strike flat field strike. Thoughts? Thanks Rich Report this Post to the Staff

Mintmarks being placed by hand were sometimes punched deeper into the die, making a resultant detail higher than others. The die caught this edge as it settled down in a NEE direction.

radatat Valued Member United States 492 Posts	Posted 05/25/2018 6:30 pm so does the die slide NNE to make this effect CB? Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 05/26/2018 01:46 am It is MD. Note on the devices above the MM? You can see the MD there also. Sometimes the mint mark is taller than the surrounding devices. Then coin contact or MD can alter the MM only. But not an RPM. The best way to tell it in not a RPM? If you see the classic step down on a outside corner of the MM, then it is not a RPM, but is MD. Report this Post to the Staff

radatat Valued Member United States 492 Posts	Posted 05/26/2018 7:19 pm Got it Coop. Thanks. I will have to study the striking process in some depth. Still don't see the mechanics of the MD. Report this Post to the Staff
