The Royal Mint, which produces the bulk of UK coinage, has certain coins more valuable than others, with experts advising to always check your collection as you might be sitting on a small fortune without even knowing it.

Now, a TikTok user has highlighted a particular 50p piece to look out for.

The account @CoinCollectingWizard, which shares insights into rare coins and boasts 136,800 followers, recently discussed the Aquatics coin from the London 2012 Olympics series issued in 2011.

Although millions of these coins were minted, the rarity lies in a version where the swimmer's face is obscured by water lines.

Finding this distinctive variant could mean it's worth up to £2,000 if you're looking to sell.

The TikToker explained: "There were many of the pieces released in 2011, but this edition with the lines makes it a rare coin to find. Not many have been found."

The video has since attracted a flurry of likes and comments, with one viewer adding: "I have exactly like this one but in Kenya."

Another simply stated: "Got one."

A third shared: "I've got one but not the rare one like the hen's teeth, not many around."
