The first signature combination
There are only two specimens of this note known to exist.
One in the Art Gallery of South Australia, and the other in the Mitchell Library in Sydney NSW.

Only one example of the second variety of this signature combination is known to exist in private hands. This note was offered at a Spink & Sons auction house in March 1987 and sold for $42,000. The only other notes of this variety known are in Bank and Museum collections.

The second signature combination
Only a dozen or so of these notes have been offered on the market since 1975.

The third [unissued] signature combination
An unissued £100 note was prepared in 1939, designed to supplement earlier issues of this denomination. The number of notes that were produced is not known, but it was found that they were not required, and all supplies except for a few specimens were destroyed. This brown note, with a central oval portrait of George VI, has a blank circle for watermark of Captain Cook at left, and on the right a circle with wreath enclosing the Australian coat of arms.

The back of the note shows a central panel depicting Dairying, which shows a man milking a cow, a woman carrying eggs in a basket, and a man with a yoke carrying a bucket. A calf, fowls and geese are in the foreground. It is stated that during 1958 all supplies of this note were destroyed except for a few specimens now held by the Reserve Bank of Australia.

The signatures are those of Harold John Sheehan, Governor Commonwealth Bank of Australia and Stuart Gordon McFarlane, Secretary to the Treasury. Serial numbers are Z over a 0 prefix, and a six-digit serial number.

On the 1st of august 2019 an incredibly rare Australian 100-pound note has set a new world record at auction, with a private collector ultimately paying more than half a million dollars to own it.

The note was auctioned by Noble Numismatics in Sydney, and subject to a fierce bidding war between two collectors.

Managing director Jim Noble told nine.com.au bids opened at $210,000, with the final price expected to be about $350,000.

But the note surpassed expectations, eventually going under the hammer for $410,000.

Adding in a buyer’s premium and GST, Mr Noble said, pushed the final total paid to $500,200.

The 1914-issued note is “perhaps the world’s rarest banknote”, the auction website states.

It was discovered in a Tasmanian deed box in the mid-1970s and has traded hands between collectors relatively rarely.

Mr Noble said he was pleased with the sale result.

“If we get the note back to sell again I’d hope we could (top the price) but as the collector’s a fairly young man that seems unlikely to happen any time soon,” he said.

The eventual buyer was an Australian private collector.
