Australians could be hanging on to a $1 that could be worth thousands of dollars, and not even know it!
A mother in Melbourne has posted on the Facebook group Melbourne with Kidz that she found a “mule” dollar coin from the year 2000.
These coins were produced due to a technical error by the Australian Mint in Canberra twenty years ago.
Mule dollars are slightly thicker than a regular $1 coin in appearance and also have a double rum around the Queen’s head.
“It’s a small number of the year 2000 $1 coins that had been minted using the incorrect obverse die (heads side) and released into circulation by mistake and only discovered a year or two later,” the mum wrote after doing some research.
“With just a 1.4 millimetre difference in diameter between the 10 cent and $1 coin, you can clearly see a double rim circle going around the edges of the coin.”
The Daily Mail reported that there are just 6000 coins that were minted incorrectly.
A few of these coins have been placed on eBay at a value ranging from $700 to $5000.
“Check your change and empty out the kids piggy bank! You could be sitting on a winner,” the mum said.
