Coin: Twenty Cents 2016 Changeover

On the 50th anniversary of Australian decimal currency, the Royal Australian Mint’s released a special series of coins commemorating the earlier, pre-decimal currency of the country. The modern circulating designs were joined by depictions of Australia's pre decimal coins on the obverse.

The story of Australian currency runs parallel with the nation's history of progression. As early European settlers improvised a monetary system, international coins, promissory notes and the infamous rum trade were all visible in the early 1800s. The first coins "minted" in Australia were created by removing a piece from the centre of a Spanish dollar, forming two separate coins known as the Holey Dollar and Dump.

The gold rush of the mid-19th Century resulted in many unofficial tokens and ingots until the Sydney Mint opened in 1855, producing sovereigns which were largely identical to their British counterparts. This English influence remained strong and the new national currency of 1910 inevitably emulated English pounds, shillings and pence.

On 14 February 1966, the changeover to decimal currency transformed the nation, as Australia joined a worldwide currency trend. The uniquely Australian images of the decimal coins are still cherished on their 50th anniversary.

As a tribute to Australia's coin history, each coin of the Changeover series features depictions of coin designs from today and years past. The twenty cent coin shows a Coat of Arms design which was shared by all of the earliest silver pre-decimal coins (Threepence, Sixpence, Shilling and Florin). Unlike earlier commemorative twenty cent coins, the commemorative design is on the obverse, while the reverse has the traditional platypus design.

Crowned mature head of Queen Elizabeth II facing right (effigy known as the "Fourth Portrait"). The Queen wears the "Girls of Great Britain and Ireland" diamond tiara, a wedding gift from Queen Mary (Her Majesty's grandmother) in 1947 - which she also has on the Machin and the Gottwald portraits.

In tiny letters below the head, the artist's initials IRB (for Ian Rank-Broadley). The effigy is much smaller than on regular coins.

Below the effigy, a stylised depiction of a coin carrying the original Coat of Arms of the Commonwealth of Australia (it featured on the earliest silver pre-decimal coins). Within a circle, a simple shield enclosing a cross of Saint George on which are five six-pointed stars, around the outside of which are six small escutcheons, i.e., small shields. The shield is supported by a kangaroo and an emu standing on a grassy mound. Above the shield a crest, the seven-pointed star of Federation on a wreath and on a ribbon at the base the motto ADVANCE AUSTRALIA is inscribed; the two arrow heads under the Coat of Arms flanked the date on pre-decimal coins; however, a denomination and date are not depicted here.

Around above, the monarch's legend and the date: ELIZABETH II AUSTRALIA 2016. Around below, FIFTY YEARS.


A platypus swimming. The denomination numeral 20 [cents] is above the head of the mammal; the artist's initials SD (for Stuart Devlin) are in (very) tiny letters, within the swirl of water around its right forepaw.
