Former Parisian money (5)
I believe the answer is:
franc
'former parisian money' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for franc that I've seen before include "Old French money" , "Unit of money" , "I'm accepted in Basle" , "Old European currency" , "It's equal to 100 centimes" .)
