10 Shillings Commercial Bank of Australia Ltd.

The Commercial Bank of Australia's wartime shilling notes were issued under the Commonwealth's 1910 Australian Notes Act framework, which had already moved to nationalise the currency — yet private banks retained limited note-issuing rights in practice through the war years, creating an awkward dual circulation that legislators never fully resolved. Sands and McDougall, primarily known as Melbourne stationers and calendar printers, produced several Australian private bank issues of this period and brought a distinctly commercial-house quality to the work rather than the security printing pedigree of dedicated banknote firms.

The series was short-lived. By 1920, private bank note issuance in Australia was effectively dead.
