After the coronation of HM Queen Elizabeth II in late 1952, the obverse of the One Penny series was changed to Mary Gillick's effigy of Her Majesty, with the legend ELIZABETH II DEI GRATIA REGINA ('Elizabeth II, by the grace of god, queen'). This first type was issued for only a single year in 1953 and was struck in both Melbourne and Perth. In 1955 the second type was issued with the obverselegend altered to read ELIZABETH II DEI GRATIA REGINA F:D ('Elizabeth II, by the grace of god, queen, defender of the faith'). The series continued to be struck until the introduction of decimal currency by both the Melbourne and Perth Mints. Across both types the reverse remained Kruger Grays iconic bounding Kangaroo design.
