2005 Mob of Roo's $1 Coin
A One Dollar Australian Coin ( $1 )
2005 Mob of Roo's
Out from general circulation
This is a very debated coin, some call it a Mule others say it isn't. They were only going to strike the 2005 coins with the dancing man, but then they struck a few with the Roo's on the back.
If you were lucky enough to buy a proof set for $80 that had one, they sold soon after for up to $3000.
Australian Threepence Dot Com have a good article on them.
Any way this is one of the few still floating around.
This coin is in very good condition for a circulated coin.
