South African money needed for material (5)

Ross

I believe the answer is:

satin

'for material' is the definition.
(satin is a kind of material)

'south african money needed' is the wordplay.
'south african' becomes 'SA' (abbreviation).
'money' becomes 'tin' (old-fashioned slang term for money).
'needed' means one lot of letters go next to another.
'sa'+'tin'='SATIN'

(Other definitions for satin that I've seen before include "Smooth glossy fabric" , "Stain on shiny fabric" , "Fine material" , "Lustrous fabric" , "Material with glossy front and dull back" .)

I've seen this clue in The Sun.
