The minting process begins with an initial design. Here the Royal Australian Mint’s designers create the image that will eventually be seen on a coin using traditional pencil and paper, a computer, or a tablet.
Afterwards, a three-dimensional model of the design is created using modelling clay, many times larger than the final size. This is then cast in plaster. The coin designer can spend many hours working on this plaster model, refinin the details of the design.
To imprint the design onto a coin it needs to be transferred from the plaster to a metal tool. A laser scanner captures all the details from the plaster cast and sends them to a computer. Details such as words, numbers or dates can be added using the computer software.
