Hi Guys,
Well when you are out beeping and you find our aussie $1 coin just keep your eye out for the year 2000. There was a mistake made in the mintage they used the dye from the ten cent coin and because the ten cent is smaller than the dollar by a bit it put another rim on the edge. They are around and a selling for a good buck. So keep your eyes peeled and you might be lucky.
