Watch List notes:

Rhodesia and Nyasaland Shilling 1955 VIP Proof/Proof of record, KM#5 the excessively rare cupro-nickel issue with a mintage of only 10 pieces, in an NGC holder and graded PF66 Ultra Cameo, we note NGC does not list Rhodesia and Nyasaland coins on their Census, however the PCGS Population Report only shows coins graded up to and including PF65, this therefore potentially the finest known example

Estimate: 525-700 GBP
