WHAT could be mistaken as pocket change might actually be worth a whopping £130k.
These three rare coins are a collectors dream and might be hiding down the back of your sofa.
Coin Collector UK is a rare coin guru who has put together a list of the three pieces of change that could upgrade your entire life.
In one of his TikTok videos he said: "You can take an early retirement if you find these coins."
The 1933 penny coin
The first of the three is the highly sought after 1933 penny coin that collectors are desperate to get their hands on.
He added: "One of these old pennies sold at for £127,000.

"The year you need to find is 1933 - less than 10 of these were ever produced.
"These are worth huge money with one selling for well over £100,000 pounds and another for about £86,000."
While there are other dates to look out for, there are only seven 1933 coins known to exist.
It was once sold for a staggering £140k and the collector predicts the next one to be found could be sold for even more.

You would be able to trade it for a supercar if you manage to spot one of these coins.
The Olympic Aquatics coin
The next rare find is the The Olympic Aquatics coin which can reach up to £2,000 due to its printing error.
There are thought to be 600 pieces of these 50p coins misprinted in 2011 ahead of the London celebrations with each being worth more than just a pretty penny.
These coins were printed with lines, mimicking water ripples, over the swimmers' head whereas her face was originally designed to be more visible.
The image was quickly changed when the Royal Mint modified the design, leaving only a few of these original coins in circulation.
This slight distortion has collectors battling over the limited edition piece, with one of the highest bidder spending £3,766 to take the precious coin home.
The Lord Kitchener £2 coin
The final one is the most recently printed coin and its details are what make it so valuable.
It is a £2 coin from 2014 featuring Lord Kitchener - a British military leader.
He is easily recognised pointing in the military recruitment posters stating: "Your country needs you."
How do I spot a rare coin?
RARE coins and valuable notes can be worth thousands of times their face value.
But sometimes it's just small differences which make them so lucrative.
The most valuable coins tend to be ones with low mintage numbers or an error.
Those qualities usually make them valuable to collectors.
Next check if your coin is still available to purchase in superior Brilliant Uncirculated quality from an official Royal Mint distributor.
Certified Brilliant Uncirculated coins have been specially struck to a superior unblemished quality which set them apart from the coins you may find in your change.
These coins can fetch up £800 - but only if it has this specific printing error.
Only a few of these have been found and one TikTok user called @thecoincollectoruk revealed what to look for.
In a TikTok video he stated: "If you find this £2 coin check it for an extremely rare error.
"The coin must lack the inscription "two pounds" on the Queen's side, otherwise it's just a regular £2 coin."
Apparently there are over 5,700,000 of the regular £2 but only a handful of the misprinted ones.
How to sell a rare coin
There are several ways you can sell rare coins - on eBay, Facebook, or in an auction.
If you're selling on Facebook, there are risks attached.
Some sellers have been targeted by scammers who say they want to buy a rare note or coin and ask for money up front to pay for a courier to pick it up.
But the courier is never sent and you're left out of pocket.
It's always best to meet a Facebook seller in person when buying or selling a rare note or coin.
Ensure it's a public meeting spot that's in a well-lit area and if you can, avoid using payment links.
You can also sell at auction, which is generally the safest option.
You can organise this with The Royal Mint's Collectors Service.
It has a team of experts who can help you authenticate and value your coin.
