Royal Australian Mint in 1967 the Melbourne mint was closed. Some staff from the Melbourne mint relocated to Canberra to operate the new mint. However it was not until the early 1980s that the RAM was able to sustain solitary production of the full set of circulating Australian coins, and so on several occasions in the 1960s and 1970s the RAM contracted production runs to the Perth Mint, the Royal Mint in both London and Llantrisant, and even on one occasion the Royal Canadian Mint. The mint consists of two buildings, an administration building, and a process building. The administration building houses the
Royal Mint as part of a wartime effort. It struck sovereign from 15 Aug 1918 til 22 Apr 1919. before closing in May 1919. A sixth and final overseas mint was established in the Union of South Africa in Pretoria on 1 January 1923, producing £83,114,575 worth of sovereigns of its lifetime. As South Africa began cutting ties with Britain, the mint closed on 30 June 1941 only to be later reopened as the South African Mint. Although just six mints were officially controlled by London's Royal Mint, many more independent mints were set up to facilitate parts of the British Empire.
