The Perth Mint has released the innovative 1oz silver gear-shaped two-coin set, illustrating historic inventions using steam and electricity. Key developments in these areas spurred industrial and technological advances resulting in what we know today as the First and Second Industrial Revolutions.
The Industrial Revolution, which began more than 200 years ago, ushered in enormous changes to human society. Handcraft workers from rural communities moved to densely packed urban environments where they were employed for long hours in grimy factories dominated by noisy machinery. Driven by the invention of new technology and adoption of new processes, the industrial revolution had dramatic effects on economics, politics and culture.
Fundamental to mechanisation was the development of Boulton and Watt's steam engine. One of its first applications was pumping water from mineshafts at the growing number of collieries required to satisfy another key facilitator of industrialisation - coal.
Beginning around 1870, the Second Industrial Revolution, also known as the Technological Revolution, marked a new, even more rapid phase of industrialisation. It was characterised by many important inventions, notably in electricity which replaced steam as the main source of industrial power.
The Two-coin set is presented in an acrylic case with a mechanism to rotate the coins. The case sits within a themed shipper and is accompanied by a numbered Certificate of Authenticity.

Depicts Thomas Edison’s incandescent light bulb. The inventor himself is shown at Pearl Street Station in front of its electrical generating equipment. The design also incorporates a representation of spectacular electrical discharges from a Tesla coil, a system invented in 1891 that produced extremely high voltages used by Nikolai Tesla in experiments aimed at achieving the wireless transmission of energy.
