A remarkable banknote in every way with abundant security features. This note had some extremely special features built into it as security against forgery. It was a world first and makes these notes highly desirable as collectors’ items. Collectors value numerous variations of this note.
The 50 dollar note embraces these following security features:
Obverse:
David Unaipon (28 September 1872, Point Mcleay (Raukkan) Mission – 7 February 1967) was an Australian Aboriginal of the Ngarrindjeri people, a preacher, inventor and writer. Today, he is featured on the Australian $50 note in commemoration. David Unaipon was awarded ten patents, including a shearing machine, but did not have enough money to get his inventions developed. He was also known as the Australian Leonardo da Vinci for his mechanical ideas, which included anticipatory drawings for a helicopter design based on the principle of a boomerang and his research into harnessing the secret of perpetual motion.
Reverse:
Dame Edith Cowan (1861–1932) is best remembered as the very first woman member of the Australian parliament. She was, however, a true Australian pioneer in many ways being a social worker, feminist and politician.
Watermark:
With the introduction of the new polymer banknotes we saw the end of the customary Cook watermark. It was replaced with the Variable Optical Security Device in the bottom corner.
Unaipon took out provisional patents for 19 inventions but was unable to afford to get any of his inventions fully patented. His most successful invention (provisional patent 15 624), a shearing machine that converted curvilineal motion into the straight line movement which is the basis of modern mechanical shears, was introduced without Unaipon receiving any financial return and, apart from a 1910 newspaper report acknowledging him as the inventor, he received no credit.
Other inventions included a centrifugal motor, a multi-radial wheel and a mechanical propulsion device. He was also known as the Australian Leonardo da Vinci for his mechanical ideas, which included pre World War I drawings for a helicopter design based on the principle of the boomerang and his research into the polarisation of light and also spent much of his life attempting to achieve perpetual motion.
