New King Charles III 50p coin is UK's rarest and could be worth more than £100

The Royal Mint website confirms that the salmon coin is currently the rarest 50p in circulation. It took the top spot from the 2009 Kew Gardens coin

A coin collector has urged Brits to check their change after revealing the rarest 50p in circulation is now worth up to £110.

The lucky coin features a salmon design and was released into circulation earlier this year. Only 200,000 of the coins were minted, making them incredibly rare.

TikTok user @changechecker posted a video showing off the coin and explaining its rarity.

He told followers: “Check your change” for the coin. “The rarest coin in the UK. This is the 2023 King Charles salmon, and this is an immaculate condition.”

This coin is particularly rare because relatively few were ever made, to begin with.

“This is one of 200,000, and this has come straight from a sealed bag,” he continued.

“Look at it. Absolutely insane. They sell for over £100 with only 200,000 minted, reports DevonLive.

"You could still possibly find one of these in your change. So make sure you check your change in case you find one of these bad boys.”

The Royal Mint website confirms that the salmon coin is currently the rarest 50p in circulation.

It took the top spot from the 2009 Kew Gardens coin, of which 210,000 were created.

As the nation’s most collectable coin, the 50p has seen more than 100 different designs appear on its reverse since its introduction.

These include special designs for the 2012 London Olympic and Paralympic Games and milestone Royal occasions such as His Majesty King Charles III coronation.

Rebecca Morgan - director of commemorative coin at The Royal Mint said: “The releasing of mintage figures is an eagerly anticipated event among the coin collecting community – and this year is particularly exciting as we reveal the Atlantic Salmon as the rarest 50p in circulation.

“For the first time in 15 years, the highly collectable Kew Gardens 50p loses its top spot as the rarest in circulation with the Atlantic Salmon 50p splashing its way to number one. 2023 marked pivotal changes for the nation’s coinage, including the introduction of coins celebrating King Charles III’s coronation entering circulation. Finding these special designs, like the Atlantic Salmon, in your change is a win for all collectors.”

On December 30, three Atlantic salmon coins were sold on eBay, each at slightly different prices - one for £102, one for £110.79 and another for £98.99.
