The Australian 1 and 2 cent coins had become virtually worthless by the late 1980's, and considering their face value, they cost a lot to produce, more so because of the rising price of copper. The last Australian 1 cent coins were put into general circulation in 1990 and the last 2 cent coins were put into general circulation in 1989. They were both progressively withdrawn from circulation in 1994 and all prices rounded off to the nearest 5 cents.
