Rare and Valuable Australian coins to collect – Prices Updated 2020


All over the world, you can see avid collectors of many valuable pieces of history. One, in particular, is collectible Australian coins. These currencies are worth thousands and even millions of dollars, case in point, the Proof 1930 Penny, which was sold to a Sydney collector for $1.15 million last year. This staggering amount comes as no surprise since it was considered as the “King” of Australian coin rarities.

What are the Australian Coins to watch out for?

There are a good handful of Australian coins worth collecting. If you want to know which ones, here is a list of the most important.

The 1894 Gold Sovereign Melbourne Mint  $711.0022 CT gold
The 2010 Perth Mint Proof Australian Sovereign$400,0091.67% pure gold.
The 2000 $1/10c Mule  $3,000Rare hybrid
The 2007 Double Obverse (Head) 5 Cent  $1,500Coin with error
The 1966 20 Cent Coin Wavy Line$2,500Special serie to watch out

The 1894 Gold Sovereign Melbourne Mint


This gold coin can be found in prominent coin collectors and is worth at least $711.00 USD. It is made of 22 CT gold and weighs 7.322 grams. Of course, with such a rare coin, you must be willing to pay for a lot of money to buy this one.

The 2010 Perth Mint Proof Australian Sovereign


The Perth Mint had resumed its regular production of gold coins or sovereigns last 2009. Because of this, it has led many avid Australian collectors to want to gain one of these remarkable coins. The Perth Mint has meticulously crafted these coins of 91.67% pure gold. These also show the Commonwealth Coat of Arms Reverse as well as the words AUSTRALIA, SOVEREIGN, and The Perth Mint’s ‘P’ mintmark. There are about 2,500 copies, which means that they are rare copies that won’t easily be collected.

Valuable Australian coin 1 cent to look for: The 2000 $1/10c Mule


Another rare coin to watch out for is the 2000 $1/10c Mule. Just this year, a Melbourne mum hit the jackpot when she was able to obtain this precious coin. She earned $3,000. The coin was produced because of a mix up at a mint that created the rare hybrid. These coins are worth the money and are even hard to find. If it has an accidental pairing of a 10 cent heads die and the normal mob of roos reverses die, then that is an authentic coin. At least thousands of these coins were minted and are circulating for years now. It would be worth your time looking out for them.

The 2007 Double Obverse (Head) 5 Cent


This should be at the top of the list but also something that you should carefully examine as a coin collector. These coins were a product of a mint worker who paired two 2007 head side dies and then running the press to mint hundreds or thousands of coins. Initially, throughout the years, they thought that there were only a few of these coins until they found too many. This meant that thousands could still be in circulation. But, the only way you can also say that it is a profitable coin is if it is high grade and authentic. This coin can actually be easily forged, so you should be apprehensive if you’re looking for one. It will be worth at least $500 to $1,500.

The 1966 20 Cent Coin, the king of Australian coins of 20 cents


This coin was introduced during the time that Australia was converting from pre-decimal to decimal currency. It has composite metals of 75% copper and 25% nickel. It has had variances over the years, but the unintentional error coins called varieties are the most profitable ones.

How to identify 1966 Wavy Line


They add value because of their rarities. There’s the 1966 Wavy Line, which was struck by the Royal Mint UK and featured a raised section on the top of the horizontal baseline of the “2”. It is worth at least $2,500 in uncirculated condition.

The History of Australian Currency

To understand Australian coin collecting better, why don’t we go over the history of currency in Australia.

Australian dollar coins

Before coins, the indigenous Australians used a barter system to exchange things such as food, shells, tools, and other raw materials. Then came the early settlers bringing with them various collections of international coins, promissory notes, and tokens. In 1813, this currency was superseded by the Australian coins called the “dump” and the “holey dollar.”


There was also the gold rush during the 1800s where gold was turned into ingots, and in 1855, the Royal Mint was opened, turning the gold coins into what is known as sovereigns. But, it was not until 1910 that the country’s national currency was formed. Before, when it was a colony, it’s official currency was the United Kingdom coinage.

During this time, their commonwealth currency was also still based on the UK’s monetary system. It had the same denominations and relative values. They had the Australian, shilling, threepence, sixpence and florin. The halfpenny and penny were introduced in 1911, while the crown in 1937. 

On 14 February 1966, Australia adopted the decimal currency system. This is what is still being used today. It replaced the penny with the cent and the pound with the dollar. The one-cent, two-cent, five-cent, ten-cent, and the one-dollar coins and more were later introduced in 1984. In 1990, circulation issues of one-cent coins were also minted. The following years then lead to the decimal system’s improvisation, which we can now see in Australia’s currency. 

The Different Types of Australian Coins You Can Collect

The Royal Australian Mint is the only place that produces all of the country’s circulating coins. For the coin collector, this should be the best place to start off your collection. They have a range of collector coins that can suit any of your budgets and interests. Here are some types of coins you should understand before starting:

Uncirculated – These coins may either have unique designs or are special versions of the circulating coin designs. These have the same materials as circulated coins and have a sharper image and more clearly-defined edges. You can often find them packaged in presentation cards.

Frosted Uncirculated – These coins are created based on the same process and technology as uncirculated coins. Their clearly defining characteristics are that they are polished and have a more striking appearance against a frosted field or background. If you are a coin collector who has a passion for certain themes and designs, then you should collect some of these to become highlights in your collection.

Proof – These coins are one of the hardest to find and are considered rarities. You can make a profit by selling them because of how valuable they are. They are usually made with metals such as gold and silver. There are only a few thousand copies available, with even some costing hundreds of dollars. These also come in presentation cases and numbered certificates of authenticity.

Antique finish – Based on the description itself, you already have a clue as to what type of coins these are. These are specially prepared to make it look like an old, treasured coin. These antique finish coins are made of blanks and are cleaned, treated, and struck to the Royal Mint’s exacting standards. Compared to other coin finishes, these coins are completely handmade, and each has its own unique characteristics to inspire nostalgia.

What Aspects to Consider when Collecting Rare Australian Coins

  • Make sure that when you collect Australian coins, there should be significant details about the history of the coin. These will help you learn more about its credibility.
  • There must be stated features of the coins to offer you some guidance. The form of the coin will influence how much it will be worth. This is because you will be identifying the dissimilarity for every grade of the coins. Thus, you’ll have an idea of its actual market value.
  • As a coin collector, you should understand that it is important to check the coin collection values from time to time because the cost can vary depending on the existing market trends. This will help when it comes to knowing when to trade.

How You Should Know the Worth of Your Australian Coins

If you are starting your collection, it is essential to know each worth of the Australian coin with the help of a coin seller or evaluator. Make sure to choose those with credible reputations. You should also know the basics of figuring out genuine collectible coins. These should consider dates, mint marks, or coin compositions, among other things. You should remember to be careful, especially if you are planning to purchase rare and valuable ones that could cost thousands of dollars. Your collectible coins can serve as your investment. Another thing to take note of is that it is not the age of the coins that have the most influence on the worth, but its scarcity and claim in the market. Australian half sovereigns are more precious than the earliest currencies, for instance.   

Final considerations about Australian Coins that are Worth Money

There are so many Australian coins worth collecting out there. You just need the dedication to be able to get them. If you are a beginner, you can start out small. There are collectible coins worth at least $50. You can then slowly save up to buy rarer and more beneficial coins. Moreover, coin collecting is enjoyable. Obtaining valuable pieces is satisfying and not to mention how some of them will be able to provide you with profits larger than you can imagine as you deeply get involved with the changing market.
