The new 12-sided £1 coin will be launched today, but the Treasury has warned it might take some time for the public to get their hands on the new currency as it trickles down to each bank and retailer.
But there are a select number of "coin hubs" around the UK where you can pick one up as soon as they're released.

The new £1 coin is designed to be the most secure in the world, and the Royal Mint is churning out 2,000 coins a minute, or 3m a day, in preparation.
The Treasury has announced all old coins need to be spent by 15 October or returned to their bank so they can be melted down and reused.
The new coin is fitted with a hologram and a hidden "high security feature" which can be detected "at speed", as well as micro-lettering and "milled edges", or grooves on alternate side. The bi-metallic new coin will be thinner, lighter and wider than its predecessor, and include the fifth coin portrait of the Queen.
