The coin is also known as the Half Crown.
*1937* King George VI was crowned in 1937 and his likeness replaced King George V on all coinage of the British Empire. He faces left and although it is custom that each new monarch faces the opposite way of the previous monarch, the abdication of Edward VIII, after a short reign, resulted in King George VI facing the same way as King George V. There were no coins struck for King Edward VIII in South Africa (some patterns exist).
The obverse design: head of King George VI. Inscription: GEORGIVS VI REX IMPERATOR. Designed by Henry Paget (HP).
The reverse design: A crowned coat of arms, the “Arms Of The Union of South Africa”, sectioned with four quarters, containing the symbols of each province of the Union. Upper left: HOPE (see description under the 1 Shilling comments), representing the Cape Province. Upper right: two running wildebeest, representing Natal Province. Lower left: an orange tree, representing the Orange Free State Province. Lower Right: Ossewa (Ox Wagon), representing the Transvaal Province. The date is split over the left and right sides of the crowned shield. Inscription: “SOUTH AFRICA” to the left, “SUID-AFRIKA” to the right and “2 1/2 SHILLINGS”, flanked by two little flowers, at the bottom center. Reverse design artist: Kruger Gray (KG below shield center bottom).
*1948* A design change was made to the obverse of the coin. The inscription was changed to GEORGIVS SEXTUS REX. With the independence of India in 1948, Great Britain was no longer regarded an empire and thus the removal of the word "IMPERATOR".
*1951* A design change was made to the reverse of the coin. The fonts were changed for all text. The “2 ½ SHILLINGS” were replaced by “2 ½ S.” and the date moved to the top center of the coin.
