A rare 50p that was designed by a Blue Peter viewer for the London 2012 Olympic games has sold for £205 on eBay.
The quirky coin was drawn by nine-year-old Florence Jackson and features an athlete doing a high jump.
According to change checking website Coin Hunter, around 2,224,000 were minted in 2011.
But a much smaller number of just under 20,000 were released in 2009 and sold on the Royal Mint website for £1.99 - these are the ones that could be valuable to collectors.
While these were never officially released into circulation, it is possible that one may have turned up in your spare change.
It was a 2009 version that recently sold on eBay for £205, with delivery included, after attracting two bids.
The same coin has previously sold for £148 on the auction site - but the amount you could get is never guaranteed when you put it up for bidding.
The 2011 edition is valued at a much lower £1.73, according to Coinhunter.
In 2010 and 2011, 29 new 50p designs were released into circulation to mark the 2012 Olympics games in London.
These are still proving popular with collectors, as a list of rarest 50p coins in circulation in 2021 featured seven Olympic coins in its top ten list.
If you have an error coin, it could be worth a lot too - but these are also much harder to find.
For example, an error coin of a swimmer for the Olympics collection sold for £600 in 2019.
