50 Pence - Elizabeth II 2nd portrait, large type

Saint Helena and Ascension were administered together as a single British Overseas Territory from 1922, but the islands sit roughly 1,300 kilometers apart in the South Atlantic — an arrangement that made issuing unified coinage a practical oddity. This 1984 piece arrived just three years after the territory had introduced its first independent decimal coinage series, replacing the earlier reliance on Saint Helena-specific issues and, before that, general British circulation stock.

The "large type" designation distinguishes this from the reduced-size 50 pence introduced for the UK in 1997 — this coin predates that change and matches the original Decimal Currency Board dimensions used throughout the Commonwealth.
