Complete List of Australian $1 Coins: History, Designs, Commemorative Issues & Collector Guide
The Australian $1 coin is one of the most recognisable coins in Australia and has become a popular denomination among collectors. Introduced in 1984 to replace the Australian one-dollar banknote, the coin is famous for its golden appearance and distinctive kangaroo design.
Over the years, the Royal Australian Mint has released standard circulation coins, commemorative $1 coins, special anniversary designs and collector editions celebrating important events, organisations and milestones in Australian history.
This guide provides a complete list of major Australian $1 circulating coin types, along with their history, designs, specifications and notable varieties.
History of the Australian $1 Coin
The Australian one-dollar coin officially entered circulation on 14 May 1984. Australia began planning a $1 coin during the 1970s because the heavily used one-dollar banknote had a relatively short service life.
Australian designer Stuart Devlin created the original reverse featuring five kangaroos. The design, commonly called the Mob of Roos, became the standard design of the denomination.
The $1 denomination has also been widely used for commemorative designs celebrating Australian history, culture, national achievements and significant anniversaries.
Australian $1 Coin Specifications
The standard Australian one-dollar circulation coin has the following specifications:
- Denomination: One Australian Dollar
- Composition: 92% copper, 6% aluminium and 2% nickel
- Weight: 9.00 grams
- Diameter: 25.00 mm
- Shape: Circular
- Edge: Interrupted milled
- Standard Reverse: Five Kangaroos
- Original Reverse Designer: Stuart Devlin
These specifications give the Australian $1 coin its familiar golden appearance.
Standard Five Kangaroos Australian $1 Coin

Major standard circulation issues include:

2026 Mob of Six Roos $1 Coin
The 2026 Australian $1 coin introduced one of the most important changes to the famous kangaroo design.
To celebrate 60 years of Australian decimal currency, the traditional five-kangaroo design was modified by adding a sixth kangaroo. The special design is officially known as the Mob of Six Roos.
The extra kangaroo represents the six decades since Australia introduced decimal currency in 1966. All Australian $1 coins dated 2026 released for circulation feature this design, with the Mint stating that the traditional five-kangaroo design is scheduled to return from 2027.
Years When Australian $1 Coins Were Not Produced for Circulation
Not every year since 1984 has included a new circulating one-dollar coin.
The Royal Australian Mint notes that:
- No $1 coins were produced in 1987.
- No $1 coins were produced in 1989, 1990 or 1991.
- No circulating $1 coins were produced in 2012.
These gaps are important when building a complete Australian $1 coin collection.
Australian $1 Collector Coins
In addition to normal circulating dollars, the Royal Australian Mint has produced a large number of non-circulating legal-tender $1 collector coins.
These include:
- Proof $1 coins
- Uncirculated collector coins
- Silver $1 coins
- Kangaroo series coins
- Lunar coins
- Military commemoratives
- Australian wildlife coins
- Cultural and historical commemoratives
- Privy-mark and mintmark coins
- Special themed sets
For example, the Mint's 2025 program included $1 silver investment coins and special uncirculated commemorative issues.
Because hundreds of collector-only $1 products have been issued, they form a separate collecting category from the circulating dollar list.
Which Australian $1 Coins Are Worth Collecting?
Collectors generally look for Australian one-dollar coins with:
- Low mintages
- Commemorative designs
- Unusual varieties
- Minting errors
- High-grade condition
- Proof or specimen finishes
- Limited collector releases
- Special mintmarks or privy marks
- Historically important designs
The 1992 $1, 2016 decimal anniversary issue, 2019 A-U-S Dollar Discovery coins, 2020 Qantas dollar, and special 2026 Mob of Six Roos are examples that attract collector interest for different reasons.
Australian $1 Coin Value
Most ordinary circulated Australian $1 coins remain worth their $1 face value unless they possess a collectible characteristic.
A coin may command a premium when it has a low mintage, recognised mint error, scarce variety, unusually high grade or special collector packaging.
Coin values can change according to collector demand and condition, so owners should compare recent authenticated auction results and established numismatic price references rather than relying solely on online asking prices.

1. The Historical Background of the $1 Coin
1.1 Currency Reform and the Move to Decimalisation
Australia's journey to decimal currency began in the 1960s. On 14 February 1966, the nation officially adopted the decimal system, replacing the complex pounds, shillings, and pence structure. While coins for 5 cents, 10 cents, 20 cents, and 50 cents were introduced simultaneously, the one-dollar note would remain in circulation for nearly two decades.
1.2 The Rationale for Replacing the One-Dollar Note
By the early 1980s, the one-dollar note, printed on cotton-based paper, showed significant wear and tear due to frequent handling. Its average circulation lifespan was around 12 months, leading to high replacement costs for the Reserve Bank of Australia. Inspired by successful transitions in other countries—such as the British pound coin's introduction—the decision was made to replace the paper note with a more durable coin.
1.3 Official Introduction on 14 May 1984
On 14 May 1984, the Royal Australian Mint released the first $1 coins into circulation. The launch was accompanied by educational campaigns informing the public about the new design, features, and benefits. Within weeks, the paper one-dollar note was phased out, marking the end of an era and establishing the $1 coin as a permanent fixture in Australian wallets and coin rolls.
2. Technical Specifications and Composition
Understanding the physical properties of the $1 coin is essential for collectors and users alike. Below are the detailed specifications:
-
Metal Composition: 92% Copper, 6% Aluminium, 2% Nickel
-
Weight: 9.00 grams
-
Diameter: 25.00 millimetres
-
Thickness: 2.80 millimetres
-
Edge: Interrupted milling with 77 notches
The unique copper-aluminium-nickel alloy, often called 'aluminium bronze,' provides the coin with a distinctive golden hue. Its composition ensures resistance to corrosion and wear, extending its circulation life to over 20 years on average.
3. Design Elements and Evolution
3.1 Obverse: Portrait of the Monarch
The obverse of the $1 coin features the effigy of the reigning British monarch, who also serves as Australia's Head of State. Over the decades, three distinct portraits have appeared:
-
Ian Rank-Broadley Portrait (1984–1998): Depicts Queen Elizabeth II facing right, wearing the Girls of Great Britain and Ireland Tiara.
-
Raphael Maklouf Portrait (1998–2019): Although Maklouf's portrait was approved, it was never used on the $1 coin; other denominations received the update.
-
Jody Clark Portrait (2019–Present): The latest depiction of Queen Elizabeth II (until her passing in 2022), created by Jody Clark. New coins minted since 2023 feature King Charles III.
Collectors value these obverse variations, especially transition pieces bearing King Charles III's portrait, as they signify a major shift in Australia's numismatic heritage.
3.2 Reverse: 'Mob of Roos' by Stuart Devlin
Australian artist Stuart Devlin's iconic 'Mob of Roos' design has graced the reverse of every standard-issue $1 coin since 1984. Depicting five bounding kangaroos—an instantly recognizable motif—the design celebrates Australia's unique wildlife and natural beauty.
3.2.1 Artistic Inspiration and Symbolism
Devlin drew inspiration from Australia's outback landscapes and the kangaroos' symbolic status as an emblem of national identity. The composition balances dynamism and cohesion, with the marsupials arrayed in an arc to suggest movement and unity.
3.2.2 Variations in Die Strikes
While the overall design remained constant, subtle variations emerged over multiple die strikes. Numismatists differentiate between early strikes, business strikes, and proof-like strikes based on details such as surface finish, relief sharpness, and rim lettering crispness.
4. Commemorative and Special Editions
Throughout its history, the Royal Australian Mint has released numerous commemorative $1 coins to honour significant events, anniversaries, and cultural icons. Below is a chronological overview of major releases:
| Year | Event/Theme | Designer/Minting Details |
|---|---|---|
| 1986 | International Year of Peace | Stuart Devlin — business strike, circulation |

5. Rarity, Errors, and Valuable Strikes
5.1 Key Rare Dates and Mintages
-
1992 Standard Issue (Mob of Roos): Mintage of approximately 8,000, making it one of the rarest regular-issue $1 coins.
-
2018 Invictus Games: Limited uncirculated run of 100,000; proof editions even scarcer.
-
2020 Donation Dollar: Although minted in millions, early release sets with mint packaging are collectible.
5.2 Notable Minting Errors
Minting errors can dramatically increase a coin's value. Some of the most sought-after error types include:
-
Mule Errors: Obverse and reverse mismatches, such as a $1 coin struck with a 10-cent obverse.
-
Double Strikes: Coins struck twice, creating a ghost image.
-
Planchet Flaws: Inclusions, laminations, or clipped planchets.
-
Off-Centre Strikes: Designs not aligned with the coin rim.
5.2.1 The 2000 Mule Error
In 2000, a rare batch of $1 coins was mistakenly struck using the obverse die intended for the 10-cent coin. Recognizable by its mismatched portrait and specifications, these error coins have fetched between AUD 1,500 and AUD 4,000 at auctions.
6. Collecting Strategies and Tips
6.1 Building a Thematic Collection
Collectors often specialize by theme—wildlife motifs, monarch portraits, or specific decades. A thematic approach provides focus and narrative coherence.
6.2 Grading and Authentication
Professional grading services, such as ICCS (International Coin Certification Service) and PCGS (Professional Coin Grading Service), authenticate coins and assign grades on a 1–70 scale. High-grade coins (MS65 and above) can command significant premiums.
6.3 Storage and Preservation
Proper storage extends the life and maintains the value of your coins. Recommended practices include:
-
Use Acid-Free Coin Flips and Albums: Prevent chemical damage.
-
Maintain Stable Temperature and Humidity: Avoid oxidation and toning.
-
Avoid Handling with Bare Hands: Use cotton gloves to prevent oils and fingerprints.
