Below is a 1970 S. Curious about your thoughts on the MM? Looks like a RPM to me. I know MM's are all hand punched in the 1970's even though this is reminiscent of Machine Doubling. The date looks like Machine Doubling. Thanks for looking.    "We are all flawed, some MD and some PMD." NYI |

@nyi, I think you have correctly diagnosed the MD on the date, but I agree with @ijn that the mintmark also has MD. This is because there are no RPMs listed for 1978-S cents (link below) and the doubling is the same width and direction in both places. http://www.varietyvista.com/02b%20L...Listings.htm"If you climb a good tree, you get a push."

I don't know, but I would guess just before being put into service. That way they would be sure that a D wouldn't be sent to the wrong branch of the mint.

If the mint mark is done, by hand, after the device is struck how can it be "machine" doubled?

The answer in explained in -makecents-'s post, above. Machine Doubling all around. No extra value I'm afraid.  |
