Brits have been advised to keep an eye out for a specific 50 pence piece that could be of significant value to collectors, potentially fetching up to £250. However, the coin must bear a particular design and have been minted in a certain year to be of high demand. The Coin Collecting Wizard, an expert who shares his knowledge on TikTok, detailed exactly what characteristics to look for. The coin of interest was minted in celebration of the 2012 London Olympics and features a high-jumping athlete, a design conceived by a child as part of a Blue Peter competition. However, it only holds substantial value if it is dated 2009. The same coin from 2011 is far more common and therefore not as valuable. "Just because you have this 50p doesn't automatically make it valuable," the expert cautioned. "Always pay attention to the details on what to look for. "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 rare coin features a picture showing an athlete in the Olympics as drawn and depicted by the young viewer back in 2009, but it's only the one dated 2009 that has value worth around £250." He clarified that approximately two million of these coins were minted in 2011, making them less desirable. "An earlier version of the coin was minted in 2009 and is much more valuable to collectors," he stated. The coin's value skyrockets when it's accompanied by its original collectible packaging. Explaining the significance, he noted: "It helps when it comes with its original packaging that includes images of presenters from the hit show. "It's sold for £257 on eBay in the past, which makes it over 500 times more than face value. This is a sought after coin among collectors. Good luck finding this very special 50p." The Britannia Coin Company on its website shed light on the backstory of the coin's design. It said: "The designs for this collection were selected from 30,000 designs submitted by the public as part of a competition – the design for the the athletics coin is slightly different however, as it was chosen as part of a Blue Peter competition. "The 2011 Athletics 50p, also known as the 'High Jump 50p', was chosen from 17,000 entries from children to the Blue Peter competition. Nine-year-old Florence Jackson won the competition and is the first ever child to have designed a UK coin from The Royal Mint. The reverse of the 2011 Athletics 50p displays Jackson's design of a high jumper jumping over a horizontal bar, the 2012 Summer Olympics logo above and '50 PENCE' below."
