Canada is set to have new money in the near future. Both the Royal Canadian Mint and the Bank of Canada have announced changes to our currency.

The Bank of Canada has announced that it will start printing bank notes on a polymer plastic material that was developed in Australia and has been used for their bank notes since 1988. There are two main reasons for the switch, durability, the plastic notes last much longer and can be recycled, and security, the plastic having the ability to add security features that are impossible to duplicate.

New MoneyThe first security feature made possible with a polymer substrate is the ability to make a transparent window of any size or shape. That in itself is very difficult to reproduce, but other additions would make reproduction impossible or so expensive that it isn't worth the attempt.

A Diffractive Optical Element can also be applied to a transparent window, so that although the window looks transparent, if you hold up the note against a distant light source, a 3-dimensional hologram is projected

New Moneybetween the note and the light source.

Dynamic optical colour shift is another possibility with polymer notes

and is a dynamic optical feature that changes colour when tilted under a light source. The bright and transient colour-switching effect is produced in the substrate layers. When viewed at different angles, it alternates between two contrasting colours, creating an optically reflective effect. The colour change is easily observed without special equipment or skill, making it easy for the public to recognize.
New MoneyThe ability of a ploymer substrate to accept a permanent emboss is an important feature which utilises a further element of
the intaglio process to enhance the security of the banknote. Metallic patches can also be printed on a note and the patch used to carry other printing effects such as using specially developed intaglio inks. It produces an optically variable colour effect where the colour of the intaglio print intensifies when viewed at a highly oblique angle to the surface of the note.

Shadow images, iridescent images, machine readable threads and a self-authenticating systems are also possible. In the latter, a window is printed with micro-lines and an image elsewhere on the note is also printed with micro-lines. The image will only show up if the note is folded so that the window lies over it.

The Bank says it is shooting for an 18 month timeline, sounds exciting.

New Money
z Meanwhile, over at the Mint, as part of the Government of Canada's budget announcement to modernize Canada's currency, the Royal Canadian Mint will change the composition of one-dollar and two-dollar coins, using the Corporation's cost-effective patented multi-ply plated steel technology.

The current composition for the one-dollar coin is bronze plated nickel, while the current composition for the two-dollar coin is, for the inner core, aluminum bronze (copper, aluminum and nickel), and for the outer ring, pure nickel. The primary new composition of both coins, to be launched at the beginning of 2011, will be multi-ply plated steel. The new coins will bear the same look and feel as the current bronze and nickel one-dollar and two-dollar coins.

The Mint's multi-ply plated steel technology is a unique electroplating process which deposits thin, alternating layers of nickel and copper over a steel core, or "blank", to produce the best quality, most economical nickel and copper based circulation coins available. Canada's one-cent, five-cent, 10-cent, 25-cent and 50-cent circulation coins have been produced with this technology since 2000. Multi-ply plated steel coins are proudly produced by the skilled technicians of the Mint's Winnipeg facility where all circulation coins, for Canada and countries from around the world, are produced.
