King George V succeeded to the throne on 6 May 1910.
Two versions of obverse were awarded during his reign, both with raised rims.
The first version shows the King in Admiral's uniform, facing left and inscribed "GEORGIVS V BRITT: OMN: REX ET IND: IMP:" around the perimeter.

The second version with the coinage effigy appeared in the 1920s and shows the King bareheaded and facing left.
The inscription around the perimeter on this version of the medal is the same as on the first.
The initials "BM" on the truncation of the King's neck are those of the designer of the obverse, Bertram Mackennal, an Australian sculptor.

Both versions have non-swiveling bar suspensions, attached to the medal with a single-toe claw and a horizontal pin through the upper edge of the medal, with double scroll claw supports on the medal rim.
