BLUE Peter fans will be well aware of the rare 50p coin that was designed to celebrate the London Olympic games in 2012. The rare coin was designed by a child and it's popular amongst collectors with its unique historyCredit: CHANGE CHECKER

Collectors are keen to get their hands on this piece of history, and its nod to the classic children's television show adds a personal stake to the value for many too.

The Blue Peter 50p was designed by fan Florence Jackson, after she won a competition that saw more than 17,000 entries on the kids TV show.

The rare coin features a picture showing an athlete in the Olympics, as drawn and depicted by the young viewer back in 2009. It made the then nine year-old, the youngest person to ever design a UK coin. But it wouldn't be until 2011 that the coin was officially minted and distributed to public hands.
