This 1918 Commonwealth of Australia one pound treasury note, bearing the Cerutty/Collins signature combination, represents one of the earliest series of pound notes issued under Commonwealth authority. Catalogued as Renniks 21 (Pick 4d), these treasury notes circulated during the final year of the First World War, a period of profound national significance as Australia's wartime economy placed extraordinary demands on the currency supply. The Cerutty/Collins pairing, with T.S. Harrison as the note printer, is among the scarcer signer combinations for this denomination, and surviving examples in any meaningful grade are genuinely difficult to locate. Serial number B312776J. PCGS has certified just 5 examples of this issue in total at this grade and above, underscoring how few have survived the intervening century in collectible condition. This piece offers a rare opportunity to acquire an early Commonwealth treasury note with third-party certification and strong eye appeal for the assigned grade.
