1910 was the first year of coinage for an independent Australia (a Commonwealth Nation). The threepence was the smallest denomination of silver coinage and also the smallest circulating coinage with respect to size and weight. All coins were minted in London and shipped to Australia as Australian minters did not yet have the capability to meet coinage demands.
The obverse, designed by George W. DeSaulles, features the bust image of King Edward VII facing right. On the outer periphery are the words "EDWARDVS VII D.G. BRITT : OMN : REX F.D. IND : IMP" (latin for "Edward VII, by Grace of God, King of all the Britons, Defender of the Faith, Emperor of India").
The reverse, designed by W.H.J. Blakemore, features the Australian Coat of Arms (also referred to as the Commonwealth Coat of Arms) based on the design granted by King Edward VII on 7 May 1908. The coat of arms features an emu and kangaroo flanking a shield under a seven pointed star all over a banner with the legend “ADVANCE AUSTRALIA”. On the outer periphery is the denomination “THREEPENCE” and year of issue.
