Possibly scent cash (5)
I believe the answer is:
cents
'cash' is the definition.
'possibly scent' is the wordplay.
'possibly' indicates anagramming the letters.
'scent' is an anagram of 'CENTS'.
(Other definitions for cents that I've seen before include "Fractions of dollar" , "money abroad" , "American coins" , "Hundredths of dollar" , "US money, e.g." .)
