Olympic two pound coin to commemorate Games handover from Britain to Brazil
The release of the two pound coin coincides with the final day of the London 2012 Games and is to commemorate the handing over of the Olympic mantle. It features two hands meeting over an Olympic relay baton to symbolise the handover of the Games from London to Rio.
The handover from London 2012 to the Rio 2016 team will take place along with the extinguishing of the Olympic Flame, which has stayed alight throughout the competition. This signals the end of the Games.
Traditionally, it is a chance to celebrate what the athletes have achieved and also for a massive party.
The 2012 closing ceremony - called A Symphony of British Music - will celebrate music as one of Britain's strongest cultural exports over the last 50 years.
Mr Gavin said: "It is about British creativity in the arts.
"There is a hell of a lot of talent and music and a hell of a lot of show in the show."
The coin is the final coin in the Olympic and Paralympic Coin collection from The Royal Mint.
More than 4,100 performers, including 3,500 adult volunteers and 380 schoolchildren from the six east London host boroughs, are involved in the ceremony.
The ceremony ends with an eight minute handover to Rio 2016, the next host Olympic city.
