Here are the first four lines of the Daily Mail Reporter's article:
It's a find that could earn a student a mint - a 50 pence piece with next year's date on.
Sarah Legg was handed the coin in her change after paying for lunch at her college and noticed an unusual design.
The silver coin features one of 29 designs by members of the public created for the Royal Mint ahead of the 2012 Olympics.
Now the 17-year-old forensic science student hopes to sell it to coin collectors to help pay her university fees after she leaves Fareham College in Hampshire.
But it all falls apart in the very next sentence:
However, the Royal Mint today said the coins have slowly been released into circulation since October so people should expect to start finding them in their change now - and their value is only 50 pence.
So: teenager finds coin that's only worth its face value and has been in circulation for two months.

UPDATE: This 'story' began life in The News, Portsmouth. The News Editor there, Graeme Patfield, explains:
[The] article did not make any claims about the coin being worth 'a mint' or more than 50p. It just pointed out the student's surprise at finding a 2011 coin in circulation in 2010, a fact which is unusual and therefore might be thought of as newsworthy (or might not - it certainly seems to have got people talking anyway). Speculation about whether it might be worth more than 50p only appeared when this story was picked up by an agency and then sold on to the nationals.
