It’s time to check your spare change and search through your couch cushions, to see if you have this rare 5 cent coin.
The coin features the head of the late Queen Elizabeth II on both sides of the coin, which is known as a double header. It was made in 2007 due to a rare minting error, with the heads rotated at 180 degrees to each other.
The coins are so rare that popular coin expert Joel Kandiah said they could be worth up to $3,000 if you manage to find one.

“[They are] very hard to come across because the mint processes are so stringent now, to find error coins in this day and age are incredible,” Kandiah, who goes by The History of Money on TikTok, said.
“They’ve been selling around the place. A few of them have sold for a couple of grand. Now the market’s pushing up to $3,000.”
One of the double-headed coins recently sold on eBay for $1,900, and there are a handful of the coins listed for sale on the platform for up to $5,000.
The Royal Australian Mint struck more than 59 million 5 cent pieces dated 2007. While it’s not known exactly how many double-headed coins were made, there’s a good chance there could be more out there.
Other rare coins
It’s not the only Aussie coin that has skyrocketed in value, thanks to small errors.
The 2000 $1 ‘mule’ coin is currently worth up to $3,000. The coins were mistakenly produced using the smaller 10 cent obverse side (the head side) and entered circulation.
Because of the error, the coins have a pronounced double rim around the obverse of the coin and they can appear off-centre.
The 1966 wavy-baseline 20 cent coin is also fetching up to $4,000. The bottom of the number ‘2’ on the tails side has an obvious wave to it, compared to standard coins, which have a straight base on the digit.
According to the Perth Mint, about 58.2 million 20 cent coins were struck dated 1966, but only very few of them feature this wavy baseline.
