To commemorate forty years since the introduction of decimal currency the Royal Australian mint has once again issued the round fifty cent design as a proof. The silver proof piece features the same composition as the original fifty cent coin (80% Silver and 20% Copper). An extremely limited pure gold proof set was also issued. In 2010 a similarly low mintage proof example of the round fifty cent was issued as part of the 2010 heritage set.

The original round fifty cent piece was a unique issue in the sense that it was the only circulation decimal coin struck with a silver content. The silver content was significantly above face value and consequently the issue was discontinued after 1966 citing that it was too easily confused with the twenty cent coin. The fifty cent was later revised in 1969 as a dodecagonal coin.
