Cents as returned in pouch (3)
I believe the answer is:
sac
'pouch' is the definition.
(I know that pouch can be written as sac)
'cents as returned' is the wordplay.
'cents' becomes 'c' (abbreviation for cents).
'returned' says the letters should be written backwards.
'c'+'as'='cas'
'cas' in reverse letter order is 'SAC'.
'in' is the link.
(Other definitions for sac that I've seen before include "Bladder" , "Distended membrane; pouch-like cavity" , "Animal or vegetable pouch" , "Bodily cavity enclosed by a membrane" , "Pouch or bag-like structure" .)
