The wheat stalks design continued into this type right until the introduction of decimal currency with the conclusion of the threepence series in 1964. This type features a slightly reworded obverse legend, 'ELIZABETH II DEI GRATIA REGINA F:D', ('Elizabeth II, by the grace of god, queen, defender of the faith'), after public outcry that the previous type omitted 'FIDEI DEF' ('defender of the faith').

All dates in the series are easy to acquire in mint state though the 1956 is quite scarce and underrated. Most dates other than the 1956 are relatively easy to acquire up to MS66 due to nice surfaces owing to the small size of the coin.

All dates in the series were struck at the Melbourne mint and do not display any mint marks.
