Pre-euro Italian coin (4)
I believe the answer is:
lira
'pre-euro italian coin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lira that I've seen before include "Monetary unit of Italy" , "Pre-euro currency unit in Italy" , "Old Spanish currency" , "Former unit of currency in Italy" , "Unit of money for 26 across" .)
