I just got this article in the mail:
http://www.numismaster.com/ta/numis...ticleId=3557The first Australian note to be sold for AUD 1,000,000+. It's a £1,000 from 1924 with the Kell-Collins signatures. "Australian £1,000 notes were used principally in settling accounts between banks."
I am wondering if there are such notes in the US and other countries too....
