Is she made of money? (5)
I believe the answer is:
penny
This clue is a double definition.
'is she' is the first definition.
'money?' is the second definition.
(I know that penny is a type of coin)
'made of' is the link.
(Other definitions for penny that I've seen before include "One hundredth of a pound" , "Little bit of 18" , "Smallest UK coin" , "Lancaster" , "British coin" .)
