A rare $1 coin could be worth thousands of dollars thanks to one minor mistake.

The Royal Australian Mint made an error when making ‘Mule Dollar’ coins – a small number of $1 coins from the year 2000 that were made using the wrong print.

The Mule dollar has a double rim around the edge. A regular $1 coin has one.

A Melbourne mum revealed the error on social media.

‘We found the famous MULE Dollar,’ she wrote on Facebook. 

‘Royal Australian Mint accidentally minted the coins using the smaller 10 cent obverse die (head side) by mistake.’

HOW TO SPOT A REAL MULE DOLLAR 

 The coin must be a dollar from the year 2000. 

There must be a clear double rim around most or all of the heads side of the coin, about 0.5mm wide.

‘With just a 1.4mm 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 said the coins are worth anywhere from $500 to $3000. 

Commenters were quick to empty their money boxes.

‘Gonna go look at my coins now, have so many,’ one user wrote.
