2018 $1 Evolution of Industry 1oz Silver Gear-Shaped Two-Coin SetThe Perth Mint have just released this 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, shaping the world in which we now live.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 Perth Mint will release no more than 1,000 of the Evolution of Industry 2018 1oz Silver Gear-Shaped Two-Coin Sets.The reverse design of the coin features developments in steam showing a number of significant inventions that contributed to the First Industrial Revolution. Imagery represents an early steam locomotive and the railways; the chimneys of Britain's mills and early factories which used steam power for driving machinery on a large scale; a flywheel and other components symbolising elements of Boulton and Watt's steam engine; and an early steamboat similar to the type pioneered for use on the Forth and Clyde canal by William Syymington.The reverse of the coin representing electricity features a representation of Thomas Edison's incandescent lightbulb. The inventor himself symbolised 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 produces extremely high voltages used by Tesla in experiments aimed at achieving wireless transmission of energy.Struck by The Perth Mint from 1oz of 99.9% pure silver the coin is issued as legal tender under the authority of the Government of Tuvalu.Each coin's obverse features the Ian Rank-Broadley effigy of Her Majesty Queen Elizabeth II , monetary denomination and the 2018 year-date.The Two-coin set is presented in an acrylic case with a mechanism to rotate the coins.
