2019 50p Coin
A Minting First – a 50p Featuring a Privy Mark Referencing the Science Behind its Shape
When the ten-shilling note was withdrawn, its replacement, the 50p, became the most valuable coin in circulation. As such, it required a design that was easily distinguishable by sight and touch without weighing down people’s pockets.
Hugh Conway and his team were up to the challenge. Armed with the knowledge of precision engineering and calling upon the services of a design office that normally worked on engines for aircraft including Concorde, they developed the world’s first seven-sided coin. A shape of constant width, it was able to roll smoothly in vending machines without changing the height.
