1 Pound

The Commonwealth Bank began printing its own notes in Melbourne from 1920, having previously relied on the Treasury Note arrangement that dated to 1910. This series marks an early phase of that in-house production, and the Miller/Collins signature combination narrows the window considerably — James Collins served as Secretary to the Treasury from 1926, placing co-signed notes in the latter portion of the 1923–1932 date range.

Australian pound notes of this period are prone to foxing and toning along the edges, a known consequence of the paper stock used at the Melbourne facility before later quality improvements. Genuinely clean survivors are less common than their issue numbers might suggest.
