Once again stumped with a MD vs DD call. Given the significant MD on the date, I'm inclined to believe the same holds true for the MM - it is MD. However, a valley on the lower S loop (A) and a slight split in Serif on the upper termination (B) has me 2nd guessing. The image with callouts is rotated about 140 counterclockwise. There are no listed attributions for this. Is the MM simply MD, possibly some debris causing the little valley? I have it soaking in Acetone ATM, I'll post new close-ups if they provide better definition.      |

Being the same direction and distance as the doubling on the date, I think that this mintmark also shows Machine Doubling. "If you climb a good tree, you get a push."

It's certainly possible to have MD and DDD on the same coin. Lincoln's bust and the other devices are soft mush. Seems to be very late die state. The metal around the mint mark is in all directions, which is not consistent with push doubling. That melted butter appearance is more consistent with Die Deterioration. The last letters in Liberty are fading into the field. So it's not out of the question that this die has been heavily polished. The 1970 looks more consistent with Machine Doubling, but Die Deterioration can produce a similar visual effect. I would personally guess in the direction of severe Die Deterioration to explain these features. |

Thx EV, I've reviewed that one before. Great write-up. I get 99% of them right but when I have an obvious break - like the last image bottom right - it throws me for a loop.

@ DOCC: if you look at your rims and what is DD for you, then you do not understand the DD's of those years. What you has it is an nice example of MD.

I finally circled back to double check markers on this coin against VV RPMs. While MD is evident this coin has the same markers as: 1970-S RPM-001 http://varietyvista.com/02b%20LC%20...0SRPM001.htmSo, BrandMeister called it, looking like significant MD with an RPM. |

@ DOCC: The markers mean nothing if was more the one die. Markers also mean more the stages of the Die in production process.
You can take how you want, but I tell you this it is not an RPM of the 1970 S
