I PURCHASED A 1970 LINCOLN CENT AND ON THE SLAB LABEL WHAT DOES S/S MEAN AND RPM-1 MEAN?

[DWLange]

S/S means that the mintmark was repunched, leaving a doubled image. RPM-1 means that it is Repunched Mintmark number one in CONECA's master listing. CONECA is the primary organization for the study of minting varieties on USA coins of the past century or so.
