Notice the dollar coin you got in change looks a little different to others you have seen? Different is good, different is unique, different can often add value!
The 2000 $1/10c Mule
Error or varieties of the Australian dollar coin are often worth more than their face value of one dollar. The most famous being the 2000 $1 mule where 6-7,000 dollars were struck with the obverse die meant for the 10c piece! Another variety is the 2001 Centenary of Federation upset where the obverse (heads) die rotated through the degrees of the clockface during the production run. The mob of roos dollar is prone to breaks of the die where you'll see cuds such as a second tail on a roo (double tail), a rabbit ear, a backpack or spew roo.
Error coins when proved to be a genuine minting mistake can add tens or hundreds of dollars value to your one dollar coin. Coins "fiddled" with in the backyard toolshed are not (it is an offense to deface currency). A rim defect known as a partial collar might see a dollar sell for $50. An off centre strike might see your dollar sell for $200. Maybe you'll be lucky like this Safeway shopper who got a $1 struck on a blank meant for a Venezuelan Bolivar in her change! See the complete errors list, a lot of which can be found on the Australian one dollar.
Dollars struck and not intended to circulation can also have a higher value, see part 2.
