KM-21, 1950 Southern Rhodesia 6 pence; copper-nickel, reeded edge; nice lustrous uncirculated, CGS UK graded UNC 85 (roughly an equivalent to Sheldon MS 64), this is a series that has seen a lot of circulation due to a robust Rhodesian economy and thus scarce in higher grades - only 10 are graded by both NGC and PCGS and only oneof them as high as MS 65.
