  • Money counterfeiting is almost as old as money itself.

  • When banknotes were first issued in Europe in 17th century,

  • they were crude and easily duplicated.

  • Some historians believe the counterfeits in circulation outnumbered real banknotes.

  • To make paper money harder to forge, there's been a stream of innovations -

  • from elaborate engraving, watermarks to security thread.

  • But these technologies couldn’t prevent a $900,000 swindle back in 1966 in Australia -

  • which is how we got plastic money.

  • In come the dollars, in come the cents

  • to replace the pounds, and the shilling and pence.

  • In 1966, Australia switched from pounds to decimal currency.

  • The country’s reserve bank issued a new range of banknotes with modern safety features -

  • including watermarks, woven metal thread

  • and raised areas thanks to being printed on Intaglio presses.

  • Soon though, fake ten-dollar notes that looked authentic began to appear.

  • In the following years, hundreds of thousands of dollars worth of Australian fake notes -

  • all with watermark and metal threads - passed into circulation,

  • undermining confidence in Australia’s new money.

  • It wasn’t the work of a sophisticated criminal mastermind,

  • but instead a shopkeeper, an artist, a photographer and a tailor.

  • Financed by career criminal Robert Kidd

  • the gang bought a colour printing press, a camera lens and some ordinary paper.

  • The photographer took pictures of a genuine note and a watermark drawn by the artist.

  • The tailor took a week’s printing training

  • and ran it with the shopkeeper in a garage.

  • The counterfeiters were soon caught,

  • but the authorities were alarmed by how easy they were able to copy the money.

  • In 1968, the then governor of the Australian central bank H.C. Coombs,

  • challenged a team of experts to create a more secure banknote.

  • A representative from camera company Kodak made the point that

  • if the new banknotes could be photographed

  • then they could also be printed and forged.

  • It inspired David Solomon, a polymer chemist.

  • He came up with a novel idea of a plastic note

  • after being given a business card printed on plastic by a Japanese professor.

  • Within a few years, Solomon’s team developed a unique polymer substrate,

  • which contains several film layers.

  • The molten polymer is forced out of a circular die in the form of a bubble.

  • The bubble is drawn up a tall vertical tower.

  • The size of this bubble and hence the film thickness

  • is controlled by the air pressure within the bubble.

  • Using polymer meant other security features could also be included.

  • See-through panels contain Optically Variable Devices -

  • holographic-style images that are hard to copy, or take a photo of.

  • Printed on plastic, it incorporates for the first time anywhere this Optically Variable Device

  • which takes on a different appearance depending on the angle at which you view it.

  • In 1988, the new technologies were first used in A$10 commemorative notes.

  • The technology has now been exported to 25 other countries.

  • As well as their security features, polymer banknotes are also cleaner

  • and they last two and a half times longer than paper notes, which offsets the increase in cost.

  • At the end of its lifecycle, the plastic note can be recycled to make other products.

  • Today plastic money is used in about 30 countries

  • and accounts for 3 percent of the world’s money.

  • In Australia, plastic notes have helped

  • keep counterfeiting low for decades,

  • especially when compared with other major currencies

  • like Euro.

  • The rate has increased in recent years though

  • as the criminals have caught up.

  • So the best solution might just be to go cashless entirely.

  • That would also help avoid the embarrassing spelling mistake

  • Australia printed on 46 million of its bills this year.

Money counterfeiting is almost as old as money itself.
