The Commonwealth Bank began printing its own notes in Melbourne from 1920, ending Australia's reliance on the British-printed Treasury notes that had circulated since 1910. This issue carries four distinct signature combinations across its undated production run — Kell/Collins, Kell/Heathershaw, Riddle/Heathershaw, and Riddle/Sheehan — reflecting the turnover of the Bank Secretary and Deputy Governor positions during a period of institutional consolidation before the Bank gained formal central banking powers in 1932.
The Riddle/Sheehan pairing is the scarcest of the four.
