Bag for money (5)
I believe the answer is:
purse
'bag for money' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for purse that I've seen before include "Sum of money as a prize - in pouch?" , "Prize money - prepare to whistle" , "Handbag or money prize" , "Winner's prize" , "Woman's wallet" .)
