The reverse design of the coin continues the original reverse of the pre-decimal two shillings and shows at its centre the shield of the Coat of Arms of South Africa, without the crest and supporters. The shield is quartered, and each quarter is a symbol of one of the four provinces of South Africa at the time the shield was granted by King George V in 1910. An ox wagon represents Transvaal Province, a woman with an anchor represents Cape Province, two wildebeests represent Natal Province and an orange tree represents the Orange Free State Province.
Below the shield, divided by its tip, the designer's initials KG (for George Kruger Gray).
Above, the date of issue: + [year] +.
Around left and around right, respectively the legend SOUTH AFRICA in English and SUID-AFRIKA in Afrikaans.
