Sweet; money (5)
I believe the answer is:
lolly
I believe this is a double definition.
'sweet' is the first definition.
(lolly is a kind of sweet)
'money' is the second definition.
(slang term)
(Other definitions for lolly that I've seen before include "Money (sl.)" , "A sucker" , "Loot, dosh" , "Cash (slang)" , "A sweet; money (slang)" .)
