The Korea Medal is a cupro-nickel medal, 36 mm in diameter, with a staight bar suspender. The obverse bears the uncrowned effigy of the Queen surreounded by the words 'ELIZABETH II DEI GRA BRITT OMN REGINA F.D'.
The reverse shows an image of Hercules fighting the Hydra, which was a symbolic representation of communism.
