Unlike other denominations, the sixpence kept the Blakemore reverse in 1938 but after the coronation of King George VI in 1937, the obverse features the uncrowned bust of King George VI facing to the left and the legend, 'GEORGIVS VI D : G : BR : OMN : REX F : D : IND : IMP' ('George VI, by the grace of god, Ruler and King of Britain, Defender of the Faith, Emperor of India') and was used up until 1948 then changed because of the independence of India. Date set collectors will have no problems completing the series with the key dates, the 1939 and 1940 being readily available in lower grades though the 1940 is very difficult to acquire in mint state. In upper grades, type set collectors would find best value in the 1938, 1942-D and 1943-D sixpence. Sixpence in this series were struck at the Melbourne, Denver and San Francisco mints with the latter two mints identifiable by a 'D' or 'S' mintmark respectively above the year.
