Currency in Capetown (4)
I believe the answer is:
rand
'currency in capetown' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rand that I've seen before include "Monetary unit in South Africa" , "Foreign currency" , "South African money" , "Unit of money in South Africa" , "our 1/4 Across [GOLD MEDALLIST] in 1964" .)
