The obverse design features the "uncrowned" effigy of Her Majesty Queen Elizabeth II by Mary Gillick, as it appeared on the original proof dollar.
In 1957, Canada amended the coat of arms it had been using since 1921.
Canadian artist Alan Beddoe was tasked with revising the arms to reflect two elements preferred by Canada's new monarch, Her Majesty Queen Elizabeth II: the use of St. Edward's Crown in place of the Tudor crown and a change of leaf colour from green to red.
Beddoe's revision was recreated two years later for the half-dollar (which has traditionally featured Canada's coat of arms) by the Mint's Master Engraver at the time, Thomas Shingles.
