The £1000 note above is an unissued Trial. The Commonwealth Bank's Notes Board resolved in 1922 that dies for a newly-designed £1000 note should be made in England, and a specimen of the new design was received in 1923. It has a perforated "SPECIMEN" in the lower-right section where a signature would normally be.

 A decision not to proceed with new notes was made in 1928. This trial piece was purchased by Monetarium in Australia in 1994 and its existence caused a minor sensation. It is speculatively valued at around A$300,000 and is in VF condition.
