Australian One Cent
Currency Issues
Machin Obverse
The Arnold Machin effigy of Queen Elizabeth II was introduced with the one cent and continued as the regular design up until 1984, after which it was used sporadically on collector coins.
Maklouf Obverse
In 1985 Australia's coin designs were updated with the Maklouf portrait of Queen Elizabeth II. This was a short lived series concluding with the end of the one cent series in 1991. Furthermore, only the 1985, 1987, 1988, 1989, and 1990 were actually issued into circulation, the other two years were issued only in mint sets.
Rank-Broadley Obverse
By the time Ian Rank-Broadley's mature portrait of Queen Elizabeth II was introduced, the one cent only appeared in commemroative issues.
