Sir Isaac Newton was the first design in the Royal Mint's Innovation in Science series, marking 375 years since the scientist's birth. The reverse design draws on Newton's work on optics and gravity, and the series went on to add further British scientific pioneers including Stephen Hawking, Rosalind Franklin, Charles Babbage and Alan Turing in later years.
As the series opener, Isaac Newton was struck in reasonable numbers for circulation and is a common, affordable find, making it a good entry point for collectors wanting to build the full Innovation in Science set.
