The primary error found on the 1976 Australian 50 cent piece is the Clamshell Split Planchet, where the coin's metal disc (planchet) splits around the rim during minting, creating a distinctive "clamshell" or crack effect, often with one half still attached. Other, rarer errors include striking on the wrong planchet (like a 20 cent planchet) and Grease Fill Die Strike errors.
1976 50 cent with a mostly split planchet but the two halves have not detached. Planchet split around three quarters of the coin's rim forming the characteristic 'clamshell' shape that gives this type of error it's name. Not seen often on 50 cent coins.
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.
Few circulating U.S. coins are as unique as the 1976 Bicentennial Kennedy Half Dollar. Its dual date, single year reverse selected by public competition, optional silver composition, and role as a gateway coin combine to make it more than pocket change.
The combination of precious-metal content, limited distribution outside mint sets, and the statistical difficulty of achieving either MS-67 for clad Type 1 dollars or PR70DCAM for silver proofs explains why a handful of 1776-1976 Eisenhower dollars command four-figure prices while the vast majority remain common.
1966 Round 50-Cent Coin
Australia's only 80% silver decimal coin quickly vanished from circulation. The rising silver value made it worth more than its face value, placing it firmly on any list of rare Australian coins and value guides.
The easiest way to identify a valuable half dollar is to check its date. This will tell you if the coin is made of silver. 1964 and Earlier: All half dollars minted in 1964 or before are 90% silver.

If they say a gentle cleaning is OK, here's what you should do:
However, there are some coins that can increase their value thanks to the practice of coin-collecting. Such is the case of the 50-cent coins called “Walking Liberty.” These coins are among the most sought after by coin hunters thanks to their artistic design and the history they represent.
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.

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.
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.
1878-S Liberty Seated Half Dollar: $28,500 – Of the 12,000 half dollars struck in 1878 at the San Francisco Mint, perhaps only 60 still exist today across all grades. Many were melted, and many others were simply worn down beyond recognition or otherwise lost to the effects of time.
The Round 50-Cent Coin (1966)
Before our 50-cent coins became dodecagons (that's a fancy word for 12-sided), they were round and made out of, wait for it… 80% SILVER. Because of their silver content, these coins were quickly pulled from circulation, making them highly sought after.
In Australia in 1977, the Royal Australian Mint produced a special circulating commemorative 50 cents coin to celebrate the 25th anniversary of the accession of Queen Elizabeth II. This silver jubilee issue was intended to be the only design for the 1977-dated 50 cents coins produced that year.

For some, it was just pocket change. For others, it was a collectible piece of the 200th anniversary of independence. Today, those same coins are collectors' favorites—some worth hundreds, even thousands of dollars. But not all 1976 Eisenhower Dollars are created equal.
The obverses carried the double-date of 1776-1976, and all-new reverses, selected in a competition among private artists, appeared on the three coins. The reverse of the Bicentennial Kennedy Half featured a front view of Independence Hall in Philadelphia, and was designed by Seth G. Huntington.
