The four Grand Slam® tournaments; Australian Open, French Open, Wimbledon and US Open, represent the zenith of world tennis competition. Wimbledon was the first of these tournaments and commenced in 1877, with the Australian Open, originally the Australasian Championships, starting in 1905. Since then, the Australian Open has been contested each year except during the two world wars and in 1986, when the tournament shifted from mid-December to mid-January. The winner of the 2012 Australian Open Men’s Singles Final will be the tournament’s 100th Australian Open Men’s Champion. The reverse of this coin features a representation of the medal that will be presented to the 100th Australian Open Men’s Champion. The obverse accurately depicts the swirl of a tennis ball. Both the obverse and reverse designs are accentuated with selective gold plating on the rim and centre of the designs. The selectively gold plated $2 proof coin will be presented in a clear plastic capsule housed in a black leatherette case with a Certificate of Authenticity, all held within a beautifully designed outer box.
