1928-S Lincoln Cent MS64RB PCGS CAC, Elusive Date! Far, far more elusive than the 1929-S or 1927-S dates that bookend it. This one we have had for a while and it also made the CAC endorsement. We’re letting it go because we bought a second example in the same grade for our set. CAC Population: 18 in 64RB, 7 finer (11/2019).
