It features a black hole represented by concentric circles, as well as his most famous equation which suggested that black holes were not completely black but emitted radiation, now known as Hawking radiation.
It's hard to imagine how you'd get something as massive as a black hole onto something as small as a 50p ($0.65) coin.
The nurse who cared for late British astrophysicist Stephen Hawking was on Tuesday banned for failing "to provide the standards of good, professional care that we expect and Professor Hawking deserved". I wanted to fit a big black hole on the tiny coin and wish he was still here chortling at the thought.More news: U.S. dollar drops amid rising sterling
The cosmologist and author of "A Brief History of Time" had been diagnosed with motor neurone disease in his 20s and went on to defy all predictions of his life-span as he made numerous discoveries as a wheelchair-bound scientist being able to speak only through a voice synthesiser.
Coin designer Edwina Ellis said that she was inspired by a lecture Hawking gave in Chile in 2008.
He will now join Charles Darwin and Sir Issac Newton, as the only scientists to have been on United Kingdom coins.More news: 49ers sign Tevin Coleman to two-year deal
Not only is it just the thing to remind you of one of the greatest minds in modern science, it's handy just in case you forget how to calculate the thermodynamic entropy of a Schwarzschild black hole of a given mass.
People can buy the commemorative coins from the Royal Mint's website, with prices starting at £10 for a brilliant uncirculated version, climbing to £795 for a gold proof coin.More news: AirPods, wireless headphones could cause cancer, scientists claim
This also implies a way to make black holes less black through the emission of a weird kind of radiation, a finding that Hawking proudly counted as one of his landmark contributions to science.
