That's just a coin contact mark on the mintmark from Post Strike Damage ( PSD). Not an Over MintMark. Errers and Varietys.

The 1956 D/S had been delisted.

1956-D/S OM-002  CONECA always called this a D/D CONECA: RPM #12 http://www.varietyvista.com/02a%20L...6DRPM012.htmCoppercoins lists it as 1956D-1OM-002 Wexler:1956-D 1¢ WOMM-001 Description: An apparent S mint mark shows NE of the D. Here is the side by side between the Op's coin and this image I posted:  Not from the same die. Locations are different for the mint marks. Edited by coop

I found a very early die stage for the OMM a couple years ago and took some pics. Here is my side-by-side with a sorta guess to show the "S". In hand it was pretty convincing as an s mint mark, not a D.  |

The 1956-D "D over S" is much more plausible than the 1956-D "D and S."  The D/S clearly is a D over something. The only two possibilities are D/S NE or D/D/D NE and E. The "D" and purported "S" are within the normal range of mint mark locations. In contrast, the "D and S" has a major problem. There are three completely different dies identified as "the" die for the "D and S." One has an intact "6" in the date (coppercoins.com). One has a broken hub "6" in the date (Wexler). One has both a broken hub "6" and a plugged "9" in the date. All three have the supposed "S" in slightly different N-S positions between the "1" and "9" of the date. All three have been certified by ANACS. |

So,a yes-no answer please. Is the OPs' coin a OMM? John1 EDIT: Quote:

The OP's coin = No. The location is not a match.

 In addition, the OMM (or D/D/D) has distinct indications of a secondary mark east and NE, which the OPs coin lacks. This is definitely not the suspected OMM. |

Just found another one of these in VV stage A. This one looks all like a D and none like an S. Just adding a pic for the record here. 1956-D Lincoln Wheat cent RPM-012  |

In a bizarre twist, I just opened a different roll of 1956-D B/U coins, and found another one of these. This one is in a slightly different die stage and now the S is nearly fully visible. Again, just tossing this image out for the record. 1956-D Lincoln Wheat cent RPM-012  |

It looks like the a has a straight serif on bottom,
Could it has started as an upside down mint mark error that got caught and the mint decided to correct by punching a d mintmark over the upside s?
