The design had to include the Olympic 2012 logo and "50 pence"
New 50 pence coins commemorating the London 2012 Olympic and Paralympic Games have been launched.
The coins each feature one of 29 major sports on the back and have been designed by people from England and Wales.
Nearly 30,000 people entered the Royal Mint competition to design the reverse of the coins.
One of the lucky winners is a mum from Leyland who studied graphic design at school - and now works in a bank!
Daniela Boothman's volleyball design will be found on millions of 50p coins in people's pockets as the new designs start to go into general circulation this month.
Natural with a net
"I feel so proud and honoured to have won such an amazing, once in a lifetime prize," she says.
"I know that my two young children will be very excited to tell their friends that their mummy created the design on a 'real' coin.
"It's really exciting, I'll be able to see it at work every day."
But she didn't chose volleyball because she's a natural with a net: "I'm not a massively sporty person unfortunately!"
Dave Knight, the Royal Mint's Director of Commemorative Coin says coming up with a design for a 50p is not an easy one.
"It's not a huge coin, but it's an interesting shape.
"It's quite a challenge to depict any sport on a coin, but I think what Daniela's done is really capture the essence of volleyball.
"She's got movement in there, she's got passion and power and a bit of grace as well, so it's an excellent design."
