Melbourne woman discovers rare mule coin worth $3k
A Melbourne woman has come across an extremely rare dollar coin that could be worth up to $3000 due to a tiny technical error in its making.
The woman announced her finding on Facebook, telling her followers she had found a famous mule dollar, which is slightly thicker than a regular $1 coin and has a distinct double rim around the Queen's head.
The particular coin, made in 2000, is considered one of the rarest of the Australian mule coins, created after a technical error by the Australian Mint.

"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 said on Facebook.

"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," she added.
According to The Right Note, only 6000 of these coins were minted in this way, and the anomaly was not picked up until 2005.
The coins on eBay range in price from $700 all the way up to $5000 with currently 12 up for auction.
"Check your change and empty out the kids piggy bank! You could be sitting on a winner!" the mum said.
