To tell if a 50-cent coin is silver, check the edge: silver coins have a solid, whitish-silver stripe, while modern clad coins show a copper-colored stripe sandwiched between the silver layers. For older U.S. coins, check the date (1964 and earlier are 90% silver; 1965-1970 are 40% silver). For Australian coins, the 1966 round 50-cent coin is 80% silver, but newer, 12-sided ones are not.
The original, round, 50-cent coin was made of 80% silver and 20% copper; but as the value of a free-floating silver price became higher, the coin's bullion value became more valuable than its face value; so that version was withdrawn from circulation and replaced with the dodecagonal cupro-nickel version.
Inspect the Edge of Your Coins
The best way to determine if your coins are silver is to view the edge of the coin. If the coin has a solid silver stripe, then you can feel confident that it's silver. If you can see a copper stripe, then the coin is clad.
Other rare 50 cent coins to look for include those from 1985 and 1993, which were other low mintage years. In 1985, only one million 50 cent coins were produced by the Mint making them worth between $15 and $40 each. In 1993, there were also only one million 50 cent coins made.
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 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.
The “Ping” Test
Silver has a distinctive acoustic resonance, producing a clear, sustained ring when struck. Gently tap the silver item with another metal object and listen to the sound it produces. Genuine silver should make a high-pitched, long-lasting ring. Base metals will produce a dull, short sound.
To test silver with vinegar, mix equal parts of white vinegar and baking soda in a bowl and stir until the baking soda is dissolved. Then, dip a clean cloth or cotton swab into the mixture and apply it to the silver object. If the object is real silver, the mixture will cause a reaction that will bubble and fizz.
Silver is not magnetic, not even with the strongest magnet. However, silver is diamagnetic. Take a silver coin, hold it at 45 degrees, a suitable magnet will slide down it slowly.
Key Dates and Collectors' Notes
1964 Kennedy Half Dollar: The only Kennedy half minted with 90% silver, making it highly sought after by collectors. 1965-1970 Kennedy Half Dollars: These contain 40% silver and are the last circulating U.S. coins made with silver.
The 1966 round 50 cent coin is a favorite among collectors, primarily due to its silver content and historical significance. As with many collectible coins, the value of a round 50 cent piece depends on several factors, including its condition, rarity, and demand among collectors.
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.
A silver half dollar's value can be anywhere from $3.69 to $2,150,000, depending on factors such as grade and rarity. Since the coin's minting, the silver half dollar has been minted and circulated for over two hundred years.
How can I tell if something is real silver? To check if something is real silver, use a magnet. Silver is non-magnetic, so if the magnet sticks strongly, it's not silver. Look for hallmarks like '925' and conduct additional tests for a comprehensive evaluation.
The best place to look for silver coins are at banks, in the form of rolls of coins. Rolls of coins can oftentimes contain pre 1965 90% silver coinage, but going through them can be quite time consuming, so we would like to share with you two strategies that will help to save you time.
That being said, you can use common household items to get a good idea if a metal isn't sterling silver...
Silver turning black is not a defect – it is a natural property of silver. If your jewellery is made of sterling silver (925/1000) and does not have a protective surface treatment such as rhodium plating, platinum plating, or another finish, it will naturally react with its environment.
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.
The 50-cent Incused Flag variety is found on some 2001 Australian 50-cent coins. Instead of the usual raised flag design on the Australian Federation emblem, the flag appears incused (sunken). This rare mistake has made the coin a popular target for collectors.
