There's £1 in the pot for the bag (6)
I believe the answer is:
valise
'the bag' is the definition.
(valise is a kind of bag)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for valise that I've seen before include "Travel bag" , "Small travelling bag or suitcase" , "Overnight case" , "Small overnight bag" , "Small piece of luggage" .)
