The one dollar coin circulating denomination (written as $1) was introduced in Australia in 1984, replacing the earlier banknotes. The original reverse design by Stuart Devlin featuring five kangaroos - known in Australia as the "Mob of Roos" design - has not been changed since its introduction.
The denomination is also used by both the Royal Australian Mint and the Perth Mint to issue an extensive range of collector coins, which are legal tender in Australia - such as this one.
This coin is part of a Royal Australian Mint non-circulating series featuring the Australian Football League (AFL) Premiership and the winning teams for the particular year; in 2012, this was the Sydney Swans football club.
The Australian Football League (AFL) is the pre-eminent and only fully professional competition of Australian rules football. It was originally named the Victorian Football League (VFL) and was founded in 1896 as a breakaway competition from the Victorian Football Association (VFA), with its inaugural season in 1897. It changed its name to Australian Football League in 1990 after expanding its competition to other Australian states in the 1980s.
The Sydney Swans are a professional Australian rules football club based in Sydney, New South Wales. The men's team competes in the Australian Football League (AFL), and the women's team in the AFL Women's (AFLW). The Swans also field a reserves men's team in the Victorian Football League (VFL). The Sydney Swans Academy, consisting of the club's best junior development signings, contests Division 2 of the men's and women's underage national championships and the Talent League. The club's origins trace back to 21 March 1873; the club commenced playing in 1874 as South Melbourne Football Club. Playing as South Melbourne, it participated in the Victorian Football Association (VFA) competition from 1878 before joining the breakaway Victorian Football League (VFL) as a founding member in 1897. Originally known as the "Bloods" in reference to the red colour used on players' guernseys, the Swan emblem was adopted in 1933 after a journalist at the time referred to them using the nickname following a large influx of Western Australian players (the swan is a symbol of Western Australia). In 1982, it became the first professional Australian football club to permanently relocate interstate (from Victoria to New South Wales). In the following year, the club was renamed the Sydney Swans. |
