Stephen Hawking is marked by a new 50p design, inspired by his iconic work on the theory of a black hole.
Edwin Ellis, who designed the coin, said: "He made heavy objects available and engaged – that's what I wanted to show.
"Hawking, in his playful best, is inviting the audience to think about watching a black hole before he dives. I wanted to fit into the big black hole of the small coin and I wish he was still here to lose his thoughts."
The son and daughter of Hawking, Tim and Lucy, were present in the Royal Mint to uncover the coin celebrated by their father.
Lucy said: "I hope my dad will be pleased to be with Sir Isaac Newton and Charles Darwin as scientists who made it for money!"
The coin was so popular because it was presented, the Royal Mint website is now struggling to cope with demand.
