Testbanknoten: Australia: Polymer Test Note printed by Note Printing Australia in the 1990s. The note is intaglio printed and beautifully designed and one of the three exisiting types with portrait of the famous painter Rembrandt at right. The note has a clear blue window with "dot" inside which makes the window look like a palette for painting. This note was used for in-house tests in different security printer companies, for example for "ink staining" tests with Polymer at Oberthur Security. This example has the serial number 001A0000273 which shows that it was printed at the very beginning of the printing process. A very rare and famous test note. Condition: UNC.
