Material appeal, money (5)
I believe the answer is:
satin
'material' is the definition.
(satin is a kind of material)
'appeal money' is the wordplay.
'appeal' becomes 'sa' (old-fashioned abbreviation for sex appeal).
'money' becomes 'tin' (I've seen this before).
'sa'+'tin'='SATIN'
(Other definitions for satin that I've seen before include "Rich cloth" , "Silky material" , "covered with?" , "Smooth and silky" , "Fine material" .)
