1951 over mintmark #1 (OMM #1)
shows a D mintmark punched almost
directly on top of an S mintmark.  
Remains of he S can be seen under
and to the left of the D.  Although not
nearly as popular as the 1944 OMM's,
it is more popular than 1952 OMM 1
and 1951 OMM 2.

1951 over mintmark #2 (OMM #2) also
shows a D mintmark punched almost
directly on top of an S mintmark.  The
bottom of the S can be seen under the D.  

Both OMM #1 and OMM #2 have been
proven to be D over S mintmarks.   Few
experts disagree on this fact.
