Florence, from Bristol, is the first child ever to work with the Royal Mint to design a UK coin.
Her design, featuring an high jumper to illustrate the sport of Athletics, beat 17,000 entries to win.
Florence was joined by Olympic gold medallist Denise Lewis and Blue Peter presenter Andy Akinwolere at the Royal Mint to strike her first coin. It is now available to buy as a limited edition commemorative coin from www.royalmint.com
Florence’s winning design is the first in a series of 29 officially licensed London 2012 50p designs by the nation, each depicting a different Olympic or Paralympic sport.
The remaining 28 designs will be revealed from 2010, the result of the Royal Mint’s biggest ever competition for the public to design UK coins.
Denise Lewis said: 'Florence has done all Olympians and Paralympians proud. Her design is simple and effective and I’m honoured to say I saw it first. Florence is a very deserving winner and her coin is a great illustration of how everyone can be a part of London 2012.'
