It late 1920 it was decided that the production of Australia's coinage would be shifted from Britain to Australia. New
dies from the Australian Shilling, Florin, Sixpence, and Threepence were produced in London for use at the Melbourne Mint
with a small 'M' mint-mark. Arrangements were also made for Australia's bronze coinage to be struck at the Royal Mint in Calcutta. The production of silver coinage at the Melbourne branch
of the Royal Mint began on the 12th of January 1916.
