New £2 London Underground Coins In Circulation

Check your change: from this week, two specially designed coins celebrating the Underground's 150th anniversary go into circulation.

Designed by Edward Barber and Jay Osgerby, who were responsible for the 2012 Olympic torch, one coin shows a train emerging from a tunnel with edging reminscent of tube map interchanges. The other is a roundel with 'MIND THE GAP' on the side.

If you're one of the first to find a coin, The Royal Mint wants to hear about it on their Facebook page or send them a tweet using the hashtag #Tubecoin.
