Iraqi currency (5)
'iraqi currency' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for dinar that I've seen before include "Currency of several Arab countries" , "money" , "currency from abroad" , "Currency of several Arab states" , "Drain (anag.)" .)
(Another definition for dinars that I've seen is " Units of money in several countries".)
