The cogwheel also known as a cog or gear was a device fundamental to the development of machinery. The rotating machine part with cut teeth is considered one of the oldest pieces of equipment known to man dating back to before the ancient Greeks. It was first referenced by mathematicians and engineers including Aristotle as early as the 4th century BCE.

The cog was one of several mechanical components that truly came into their own during the Industrial Revolution.

In 1835 the English inventor Joseph Whitworth patented the first gear ‘hobbing’ process to cut spiral gears. Synonymous in the modern world with engineering progression and history the gear has become an icon of industry.

The reverse of each gear-shaped coin depicts several toothed cogs ascending in size from the centre of the coin.
