Australia has a long and storied history of coinage. It’s where the first coins were minted, and many different types of currency have come into circulation over the centuries.
Maybe you’re like me and curious about the most valuable and rare coins in Australia; no need to worry! This article will cover the topic and how valuable they are!
10 of the Most Valuable and Rare Australian Coins:
Proof 1930 Penny
One of the most valuable and rare Australian coins is a proof penny minted in 1930.
This coin was made in minimal numbers and is considered the most beautiful of all Australian pennies.
It was minted in Melbourne, Perth, and Sydney, but only by one mint worker who designed them as a gift for his mother-in-law.
The latest sale of this rare Australian penny was last March 2019 for A$1.15 million!
With only six minted, three are held by private collectors, and the other three are held at the British Museum, Museum of Victoria, and the Art Gallery of South Australia.
1855 Sydney Mint Sovereign
The Sydney Mint Sovereign is the circulation’s most valuable and rare Australian coin.
It’s made of gold and has a face value of one pound. This means it could be used as payment for goods and services when there was no currency in Australia.
The Sydney Mint Sovereign can be worth hundreds or thousands of dollars depending on its condition, type, and year.
For example, one 1855 Sydney mint sovereign sold for A$95,000 in 2021!
1920 Kookaburra Square Penny
The 1920 Kookaburra Square Penny is a particularly unusual Australian coin. Not only is it one of the most valuable coins in Australia, but it’s also relatively rare.
The penny was minted between 1919 and 1926, but only around 40 examples are thought to remain today. In the early ’70s, this coin was only worth less than A$ 1,000, but by the ’90s, the price jumped to $10,000! And in 2021, one was sold for A$ 65,000!
1852 Cracked Die Adelaide Pound
The Mortimer Hammel 1852 Cracked Die Adelaide Pound is worth about A$600,000.
It’s the only known example of this coin and was discovered in the early 1980s by Mortimer Hammel. This was the nation’s first gold coin.
This coin is defined by a beaded inner circle, having a crack in the DWT lettering of the coin.
This mishap created an extremely rare subgroup of coins with only 40 pieces in the said group!
1922-1921 Threepence
One of the rarest Australian circulation coins, the 1922-1921 Threepence, was sold in 2021 for A$95,000!
This coin features the overdate where the coin was struck from a die with a trace of the previous year, 1922 covered 1921.
A Diamond Pearl 1923 Half Penny
The “Diamond Pearl” is a rare and valuable coin minted in the Melbourne Mint in 1923.
The coin is unique because it has a diamond pearl on the reverse side, which makes it unique from other coins.
The value of this particular coin can be attributed to its unique design and lack of availability, as this minting facility produced only 15,000.
The diamond-pearl is listed to have a value of A$95,000!
1894 Gold Sovereign Melbourne Mint
The 1894 Gold Sovereign was minted in Melbourne, Australia. The coin was made of 22-karat gold with a face value of AU$10 (Australian dollars).
It weighs 0.27 troy ounces, roughly equivalent to an ounce and a half in American currency.
The Australian market is experiencing high demand for these coins from collectors and investors alike as it’s one of the most valuable gold coins ever produced by the Royal Mint in London. This coin is said to be worth at least $711!
2010 Perth Mint Proof Australian Sovereign
The Perth Mint is a rare Australian coin meticulously crafted from 91.67% pure gold. They show the Commonwealth Coat of Arms on the reverse and the words AUSTRALIA, SOVEREIGN, and Perth’s Mint “P” mintmark. Unfortunately, there are only 2,500 copies of this coin!
2000 $1/10c Mule
The 2000 $1/10c Mule is the most valuable Australian coin. It is a coin that two dies of different designs have struck.
This type of coin is hard to find because this was produced due to a mix-up in the mint that created this rare hybrid coin.
However, it is said that these coins are worth around $3,000! This coin is so valuable because it was produced by mistake during production at the Royal Australian Mint in 2000 when Australia decided to introduce a new set of coins for its 50th anniversary.
2007 Double Obverse 5 Cent
Known as “Double Headed,” this coin was produced by a worker who paired two 2007 head side dies and then ran the press to mint coins.
It was thought there were only a few of these coins until they found too many over the years.
Unfortunately, this coin is also forged easily, so be careful if you want one to add to your collection. The value of the authentic coin varies from $500 to $1,000!
