The Kangaroo design continued into this type right until the introduction of decimal currency with the conclusion of the penny 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 1959 plain from the Melbourne mint is quite scarce. Finding any date beyond MS64 is a challenge though they do turn up from time to time.
The series was struck by both the Melbourne and Perth mints with the Perth minted pennies featuring a dot after the 'Y' of 'PENNY'.
