CSIRO Test Note for the Reserve Bank of Australia, an early polymer test note for $50, 1975, serial number STU 789018, very fine, but note that these notes do not exist in high grades due to all of them being submitted for ‘wear and tear’ testing in a controlled environment, very scarce and amongst the earliest polymer notes ever produced
