1 Shilling - Elizabeth II 1st portrait, Silver Proof

The Federation of Rhodesia and Nyasaland was a short-lived political experiment — formed in 1953 over the vociferous objections of Black African leaders who correctly predicted it would entrench white minority political dominance. This proof issue appeared just two years into the federation's existence, at a moment when British officials still believed the arrangement viable. The federation collapsed in 1963, leaving behind a remarkably brief coinage series.

The .500 silver proof strikes of 1955 were produced in small numbers for collectors, as circulation pieces of this denomination used the same alloy — a reduced silver standard already in effect across much of British colonial coinage by that point.
