Brits have been urged to look out for four rare coins worth a small fortune. An expert explained that combined these pieces could sell for almost £140,000, joking they will “make you a millionaire”.

Speaking on social media platform TikTok, an expert known as the Coin Collecting Wizard detailed what to look for. Speaking to his more than 260,000 followers, he said: “Coins to look out for that will make you a millionaire! Wait till you see number four.

“Save this, you don’t want to miss this one!” The first coin he detailed was the 1933 penny coin.

The reverse (tail side) of this precious penny showcases Britannia wielding a trident, while King George V’s portrait is on the other side.

It is particularly sought after due to the fact that only an estimated six or seven were minted by the Royal Mint.

He said: “The rarity of the 1933 UK penny makes it highly sought after by collectors and its scarcity contributes significantly to its market value. If you happen to have a 1933 UK penny in your possession then you are 100% rich and can easily sell this coin for over £100,000.”

On the video’s caption he noted that this coin could be worth as much as £130,000. Next, he told people to keep an eye out for a 2p from 1983.

If this has an error where it says “new pence” on its reverse side. This is because all 2p coins minted between 1971 and 1981 were marked as “new pence”.

Although this was changed to “two pence” in 1982, some were incorrectly produced. He continued: “The 1983 new pence two pence coin from the United Kingdom is considered rare due to a specific transition in the design of the coin.

“In 1983, the Royal Mint in the UK began the process of changing the inscription on the two pence coin from new pence to two pence. If you find this rare coin, you are looking at £1,000 plus.”

On the screen he suggested you could get as much as £1,500 for this coin. Then he referenced a coin designed to commemorate the 2012 London Olympics.

This 50p depicts a swimmer on its reverse side. But you want to find the rarer version with water lines going over the swimmer’s face.

The expert said: “If you find an aquatic 50p error coin with lines over the face, it could be worth a small fortune. A small handful of this original design was put into circulation, but it was then adapted very quickly to show the face above the water.

“With so few of the original design out there, it’s meant the coin’s value has been pushed up significantly.” He speculated that this coin could sell for £2,000.

Finally, he advised people to look for a gold-proof version of the Kew Gardens 50p coin from 2009. This is worth around £6,000 he said.

He added: “A gold-proof Kew Gardens 50p has recently sold for £6,800 at the Royal Mint’s online auction. The ultra-rare version of the sought-after Kew Gardens 50p was estimated to fetch between £5,000 and £6,000 and the starting bid for the coin attracted £4,000.”
