Cardinal George Pell, Catholic Archbishop of Sydney, unveils Australia's first pure gold (L) and silver (R) coins commemorating the canonisation of Mary MacKillop in Sydney on September 30, 2010. MacKillop is set to become Australia's first saint when she is canonised by Pope Benedict XVI in Rome on October 17, 101 years after her death. Only 7,500 silver coins will be issued by The Perth Mint, while the stricter mintage of 2,010 gold coins recognises the year in which she became a saint.
