The circulation issues are, 1984, 1985, 1991, 1994, 1995, 1998, 2000, 2004, 2005, 2006, 2007.
Unless I am mistaken, the rest are NCLT and consist of, 1987, 1989 and 1990. Cheers.
The 1991 Mob was not actually issued for circulation. It was available at the Mint from the Visitors Gallery "mint your own" presses and in the Uncirculated Mint Set.
All of the above years and 2008 are also available in Aluminium Bronze Proof finish with the 2004 proof being a hologram image (very nice). From the Wedding sets you can get 2004, 2006, 2007 and 2008 in Brilliant Uncirculated (specimen) finish. You can also get Sterling Silver Proof Mob of Roos for 1990 and 1991, Pure Silver Proof for 2004 and 2006 and Pure Gold Proof for 2006. There is also a Pure Silver 40mm proof dated 2004. In 1988, an Aboriginal Art style single Roo was issued for the Bicentenary of European Settlement. This is also available in proof. And sterling silver proof in two dates, 1988 and 1990. Another stylised mob of roos in pure silver date 2004 has a wavy or scrolly twelve pointed edge/rim.
Happy collecting.
