The matt Proof finish to what are usually brilliant Proof coins was used especially at the Royal Mint for photographic purposes, from around the mid-1920's until as late as the mid 1970's. As flash photography was used to illustrate promotional material, the brilliant Proofs caused too much reflection in the resulting imaging at this period of time, to be acceptable and it was much easier to literally strike one or two examples with a satin matt finish, to not reflect the flash bulb in those days before digital imaging was possible.
Bertram Mackennal (1863-1931) was the Australian engraver (later knighted) responsible for the obverse design. George Kruger Gray (1880-1943) was responsible for designing and engraving all the reverse designs.
