Fresh from their Olympic torch success at the London 2012 Games, Barber Osgerby has made British history once again by designing a £2 coin to commemorate the 150th anniversary of the London Underground. Edward Barber and Jay Osgerby have created a collectable ‘train’ coin for The Royal Mint featuring a 1967 Victoria line train emerging from a tunnel - part of a fleet that ran for a staggering 44 years - making it one of the most easily recognizable trains on the network.

The designers have subtly engraved the coin's nickel-brass edge with the stations along the London Underground line, inspired by Harry Beck’s iconic Tube map. The coin is inscribed with the New Johnston font, a typeface synonymous with the world’s oldest mass transit system and the millions of commuters who pass through it daily.

The £2 coin lent itself perfectly to a Tube-inspired design. 'Its form is naturally reminiscent of the Roundel that is the universal logo of the London Underground,’ say the designers.

London has celebrated a colossal year of milestones and the momentum shows no sign of slowing into the new year when the coins go into mass circulation come January. The pair will also be vying for gold – and another possible hat trick – in our annual Wallpaper* Design Awards, where they are up for Designer of the Year.
