Australia 2003 $5 1oz Coloured Silver Proof Coin – Volunteers Hologram Finale
The third and final coin in the 'Finale Coin' three year series celebrates the work done by Australia's many willing volunteers. The hologram shows three ordinary Australian faces signifying that anyone can become a volunteer. An arryay of images appears around the faces showing some of the volunteer activities engaged in by Australians of all walks of life ranging from firefighting to conservation and the care of young people.
The hologram utilises a method pioneered and patented by Australia's CSIRO (Commonwealth Scientific & Industrial Research Organisation) known as EXELGRAM. The optically variable properties of the image are produced by an extremely fine pattern of ridges. This ridge pattern known as a 'diffraction grating' causes light striking the image to be split into its component colours according to the spacing of the ridges in different parts of the design.
