Check your change folks. Apparently the Royal Mint's been firing out some fancy new commemorative £2 coins via London Tube stations, celebrating 150 years of the London Underground. The first load has been given to select tube stations for doling out in change, before a wide release later this year.

I can't say I've spotted either of them, but, honestly, I can't remember the last time I paid for anything at a tube station with cash. Two different designs have been issued: one from the Olympic Torch designers (the tube train shooting out of the coin), and one from Edwina Ellis featuring the classic London Underground logo.

I have yet to see any of the Olympic 50p coins that are apparently in circulation, so I doubt I'll actually see any of these beauties. I'll just have to be content with my DNA double-helix £2 that I've had for years, which reminds me of my days of genetic engineering. Or, I guess I could just buy a set of them from the Royal Mint, but where's the fun in that? [Royal Mint via TimeOut]
