The Separated OMMs

         There is only one OMM which some currently list where the original mintmark was for one mint and the primary mintmark is for a different mint and both mintmarks are totally separated from each other.  CONECA has recently re-evaluated the 1956-D OMM-001 and has delisted it as an OMM.  A second separated OMM, the 1980-D&S OMM-001 was recently debunked as die damage.
