That $1 Coin In Your Pocket Could Be Worth $1000

It might be a good idea to start checking all that loose change you've got floating around.

Start checking your pockets and emptying that bowl you keep throwing your spare change into because rare $1 coins minted in 2000 are now fetching $1000 (or more).

The gold coins, known as the '$1/10c mule', have a distinctive double rim on the Queen side as a result of an error at the Royal Australian Mint, according to the Australian Coin Collecting Blog.

"The obverse of some of the 2000 $1 dollar coins had been minted using the Australian 10 cent obverse die by mistake," the ACCB says.

"With just a 1.4 millimetre difference in diameter between the 10 cent and $1 coin the error went unnoticed, and the legendary 2000 $1 'mule' was released into the wild."

There are currently a few 'mule' coins listed for sale on ebay, with some sellers asking for as much as $8,500.


However, as conceded by the ACCB, a coins value will ultimately be determined by the buyer, so those hoping to fetch outrageous prices might find themselves waiting a long time. Although, just this month, one of the coins did sell for $1500.

Others that have fetched prices ranging from $425 all the way to $2742.
