20 Dollars - Teller Training Note

Teller training notes were produced by the Reserve Bank of Australia to allow bank staff to practice cash-handling procedures without using — or risking — genuine currency. They replicate the physical feel and approximate dimensions of the real series but are overprinted or marked to prevent any possibility of passing them as legal tender. The RBA has issued training material across multiple decimal series, and these notes occasionally surface in collector hands after being disposed of through institutional channels rather than formal destruction programs.

Acquiring one intact is partly a matter of timing — many were deliberately defaced or shredded after training cycles ended.
