Grandmother hiding money? (4)

I believe the answer is:

rand

'money?' is the definition.
(currency of South Africa)

'grandmother hiding' is the wordplay.
'hiding' indicates a hidden word.
'RAND' is hidden in the letters of 'grandmother'.

(Other definitions for rand that I've seen before include "Overseas money" , "Monetary unit in South Africa" , "Foreign currency" , "our 1/4 Across [GOLD MEDALLIST] in 1964" , "Unit of money in South Africa" .)

I've seen this clue in The Irish Times.
