*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 circle containing two sparrows, facing each other, sitting on a branch of a Mimosa tree. Inscription: SOUTH AFRICA to the left and SUID-AFRIKA to the right of the coin. The date top center and the denomination "1/4D." bottom center. Designed by Kruger Gray (KG).
*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 Afrikaans "SUID-AFRIKA" moved to the left of the coin and "SOUTH AFRICA" to the right. The fonts were changed for all text.
