Between 1996 and 2011 the Royal Australian Mint released a special subscription dollar every year with the excepton of 2001. The subscription series was distinct as each issue was made to order. This meant that the total mintage was limited to the number of orders that had been made in advance of mintage. The series commemorated Australian numismatic history with a number of signficant designs being restruck as well as coins celebrating milestones such as a century of Australian coinage.
