Yes, Australia has minted 30-cent coins, but they are special commemorative collector's items, not standard currency for everyday use, with the first and only ones being part of the 2021 "30 Years of The Wiggles" set, featuring coloured, scalloped coins issued by the Royal Australian Mint.
The twenty cent coin was first introduced with decimal currency on 14 February 1966. The original reverse design of a platypus remained unchanged until 1995. This denomination has since been used for commemorative designs.
The twenty five-cent coin of the Australian decimal currency system was issued as a part of a 14-coin collectors' set on from 10 April 2016 to 23 April 2016.
The rare Australian coin that sells for around $60,000 (or more, depending on condition) is the 1930 Australian Penny, an accidentally minted coin from the Great Depression era with a very low mintage, making it a "numismatic superstar" sought by collectors for its rarity and historical significance. Its value comes from being the lowest mintage pre-decimal Australian coin, with only about 1,500 believed to exist in circulation, notes 9News.com.au and Network Ten.
The fifty cent coin was first introduced with decimal currency on 14 February 1966. The original design featured the Commonwealth Coat of Arms struck on a coin made from 80% silver.
The 50-cent coin that can be worth around $15,000 is the rare 1988 Australian 50c error coin, mistakenly struck with the standard Coat of Arms instead of the commemorative First Fleet design, with only a couple known, though more might be found; it's a "mule" error from the Royal Australian Mint, making it extremely valuable to collectors.
The Australian 2020 Firefighter $2 coin with the rare "bullseye error," where the flame design is mistakenly printed over the Queen's face instead of between the firefighters, can be worth up to $6,000 in mint condition, with an uncirculated example selling for nearly that amount. While other error coins exist, this specific minting mistake makes the Firefighter coin a highly sought-after treasure for collectors.
Coins worth over $1 million are typically extremely rare historical U.S. gold and silver coins (like the 1933 Double Eagle or 1794 Flowing Hair Dollar) or modern ultra-rare novelties (like the 100kg Canadian Gold Maple Leaf) with few known examples, often due to minting errors, historical significance, or extreme scarcity, with sales reaching tens of millions.
An Australian 2000 $1 "Mule" coin, created by mistake using the smaller 10-cent coin's head (obverse) die, can be worth up to $3,000 due to its distinct double rim and off-center appearance, but its value depends heavily on its condition, with only a few thousand believed to exist.
The Australian commemorative $200 gold coin series was introduced in September 1980, some eight months after the gold price peaked at around US$850 per ounce. The series ran until 1994, mintage figures declined each and every year along the way. The 1992 $200 coin features the Echidna in an Australian bush scene.
Bluey $1 coin values vary greatly, from face value (if found in change) to hundreds of dollars for special coloured, silver proof, or gold versions sold by the Royal Australian Mint (RAM), with 2025 Christmas coins selling for up to $350+ online, while standard 2024 Dollarbucks in sets fetch over $300, showing high collector demand beyond their $1 face value.
Yes, 1c and 2c pieces are still Australian legal tender, but they are not considered as 'currency' (or, money that is officially released for circulation). This means that you can take your old 1c and 2c coins to the bank and exchange them for currency totalling the same face value.
A 1980 Australian $200 Koala gold coin is worth significantly more than its face value, primarily based on its gold content (10g of 22ct gold) and current gold price, but also with some numismatic value, often trading in the range of AU$1,500 to over AU$2,000 depending on the market, condition (proof vs. uncirculated), and dealer, as it contains about 0.295 troy ounces of pure gold.
1966 Wavy Baseline 20c Coin
Why It's Special: This is one of the rarest Australian coins there is, and one that's understood to be very valuable. “Turn (a 1966 20c coin) over to the tails side and look at the bottom of the number '2',” says Kandiah in a post about the coin.
25 million of these coins were struck, so they are not rare at all when in used condition. Some collectors are prepared to pay a premium for them in mint condition - as the images here show, this coin certainly meets that standard.

Here are 10 rare coins, including five still in circulation, that are certain to increase in value in the next five years.
The rarest and most valuable Australian $1 coin is widely considered the 2000 $1/10c Mule, an error coin with a double rim, created by using the wrong die (a 10c die for the Queen's head) and highly sought after by collectors, potentially worth thousands. Other contenders for rarity include the highly elusive 1992 Mob of Roos (with a claimed 8,000 mintage, though sightings are extremely rare) and error coins like the 2001 Centenary of Federation rotation error.
The three-dollar piece was a gold coin produced by the United States Bureau of the Mint from 1854 to 1889. Authorized by the Act of February 21, 1853, the coin was designed by Mint Chief Engraver James B. Longacre.

The rarest and most valuable Australian $2 coins are often error coins or those with extremely low mintages, with the 2012 Red Poppy 'C' Mintmark (with the C for Canberra mintmark) being exceptionally rare (only 40,000+ minted) and valuable (potentially hundreds of dollars), alongside the standard 2012 Red Poppy and 2013 Purple Coronation, due to their low circulation numbers, making them highly sought by collectors. Error coins, like the infamous Bushfire ''Bullseye'' Error Coin, can fetch thousands.
This rare 1988 Australian $2 coin features the HH initials and a thick edge. Made of nickel and struck in proof-like quality, it is a valuable addition to any coin collection. The coin is from the 1900s era and has a decimal denomination.
Coloured Australian $2 coins vary greatly in value, from face value to hundreds of dollars, depending on the specific design, year, rarity (like low mintage or special 'C' mintmarks), condition, and if it has errors; popular valuable ones include the 2012 Red Poppy (especially C-mintmark), the 2013 Coronation (purple), and low-mintage Tooth Fairy coins, while recent Olympic or commemorative coins often fetch modest premiums unless error or specific mintmark.
