In the mid-1960s Qatar and Dubai entered a currency union and organised the design and production of their own coin set. This joint currency was issued in 1966. The country names and denominations appear on the obverse, whilst a relatively simple design of a goitred gazelle adorns the reverse of all the coins (originally destined for the common currency to be used by Arab states of the Persian Gulf). The obverse and reverse of the coins were designed by Christopher Ironside.
