| 正面描述 | Fifth definitive effigy of Queen Elizabeth II facing right, depicting her crowned with the George IV State Diadem and wearing a draped neckline. The portrait was designed by Jody Clark and introduced in 2015. The sovereign's titles appear in Latin as a continuous legend around the obverse field, with the denomination and date incorporated into the inscription. |

Issued the year after Hawking's death in March 2018, this piece was part of the Royal Mint's Innovation in Science series — a program that had already commemorated Isaac Newton and Charles Darwin. Hawking's inclusion prompted some debate, given that his most significant theoretical work on black hole radiation remains experimentally unconfirmed; the Royal Mint was, in effect, honoring a reputation as much as a proven body of discovery.
Struck in 22-carat gold at a modest 15.5g, the specification mirrors the standard half-sovereign planchet weight — a practical choice that kept production costs predictable within an existing infrastructure.
