@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.  |

If the coins had the mintmark punched into the coin then the mintmark would be incuse. The punch used on the, thus all the mintmarks will be a match for that die. Thus if there is a RPM, then it would be on every coin struck with that die. So the incuse mark on the die, will leave a raised mintmark on the coin:  Post 1990 coins have the mintmarks on the design of their dies. Thus no more were to be punched into the dies after 1990. (well most of the time) CoopHome: How are mintmarks added to the 1989 back coins? hand punched into the dies |
