Sir Isaac Newton 50p minting error could be worth a fortune

As shared by TikTok user UKCoinHunt, the minting error appears on a small number of the commemorative Sir Isaac Newton 50p pieces.

A small minting error on a 50p coin could see it sell for an incredible sum of up to £750, according to a coin expert.

The minting error on the Sir Isaac Newton 50p coin has been shared widely on TikTok, with one coin expert revealing that the coin usually sells for around £45.

However, the coin minting error saw the coin sell for an incredible sum of up to £750.

The minting error appears on a small number of the commemorative Sir Isaac Newton 50p pieces, as shared by TikTok user UKCoinHunt.

The 50p coin was minted and issued in 2017 and the reverse design sees elements of Proposition 11 from Book One of Newton’s Principia Mathematica.

The error on the coin relates to the die clash that left incorrect marks on the 50p coin.

The 50p coin error that makes it extremely valuable

Speaking on TikTok, the coin expert said: “You've got the normal one that's completely fine.”

Adding: “When I show you the error version, if I spin this around (to the bust of Queen Elizabeth II), as you can see, you've got the scratches.”

Explaining: “You can see the lines coming out like that, this is the die clash error version.”

Up close, the error looks like two parallel lines on the left of the late Queen's neck.

When the coin was first released, the Royal Mint explained the reason behind its creation: “When Sir Isaac Newton came to The Royal Mint, Britain's finances were approaching crisis.

“Up to one in ten circulating coins were believed to be forged. His vision of matchless quality led him to root out and prosecute notorious counterfeiters, improve assaying techniques (the way coin quality is checked) and refine weights and measures to standards never seen before.
