Notes:
Although the Sixpence maintained the same reverse design for the entire series, small changes did occur to the denticles. The 1910 Edward VII Sixpence reverse featured 140 denticles and this was maintained on the George V sixpences until 1923 when 143 denticles were added to the rim. It is possible that the Melbourne Mint was responsible for adding the edge detail to a new master die, as the British sixpence of the same date carried 145 denticles, but the superior finish of the 1923 sixpences would suggest that the completed master tools were supplied to Melbourne by the London Mint. Except for the London-struck 1951 PL Sixpence, all Australian sixpences from 1923 on carried 143 reverse edge denticles until the last sixpence was struck in 1963.
