What is Junk Silver?
If you’ve inherited a jar of old coins or found pre-1965 quarters tucked away, you may already own silver without realizing it. These coins — often called “junk silver” — can hold real value tied to today’s silver prices, which remain relatively accessible compared to gold. Despite the name, junk silver isn’t worthless. The term refers to older circulating coins that contain silver but aren’t considered rare or collectible. Before the mid-1960s, the United States Mint used silver in everyday coinage. Today, these coins are valued primarily for their metal content rather than their rarity.
What is junk silver?
Junk silver is the industry term for silver coins that have no numismatic value, meaning they aren’t of interest to rare coin collectors. With a few exceptions, the U.S. Mint stopped using silver in circulating coins after the Coinage Act of 1965, but that’s recent enough that many of these coins are still available through dealers and collectors today. They’re often worn from years of circulation or were minted in such high quantities that they aren’t considered rare. Instead, their value is tied directly to the amount of silver they contain. The word “junk,” therefore, refers only to their lack of collectible appeal, not the quality of the metal. These coins remain a legitimate source of high-purity silver.
How to tell if you already own junk silver
If you’ve inherited coins or have a jar tucked away, a few quick checks can help you determine whether they contain silver:
- Check the date: Most U.S. dimes, quarters and half dollars minted 1964 or earlier contain 90% silver.
- Look at the edge: Silver coins have a solid gray edge, while newer coins show a copper stripe.
- Listen to the sound: When gently dropped, silver coins tend to produce a higher-pitched “ring” compared to modern coins.
If your coins meet these criteria, they may have value beyond their face amount—based on their silver content.
TIP: While it was once possible to find silver coins in circulation or bank rolls, this is now extremely rare, as most have already been identified and removed by collectors and investors over time.
How junk silver is valued
The price of junk silver is based on its melt value — the value of the silver content if the coin were melted down. In this context, junk silver is sometimes also referred to as “scrap silver,” meaning silver that is valued primarily for its metal content rather than collectibility.
This value depends on two main factors: the current market price of silver and the amount of silver in the coins. For example, $1.00 in face value of 90% silver coins contains about 0.715 troy ounces of pure silver. If silver is trading at $25 per ounce, that $1.00 in coins could be worth roughly $17 to $18 before dealer premiums.
Because individual coins contain small amounts of silver, dealers typically sell junk silver in bulk, grouped by face value — often in $100, $500 or $1,000 increments. You’ll also see pricing quoted as a multiple of face value. For instance, “20x face” means $1.00 in coins would cost $20. This multiple rises or falls with silver prices and market demand. Source

When Were Dimes and Quarters Made Of Silver?
What Dimes Are Made of Silver?
The main types of dime that were made of silver were the Barber dimes, Mercury dimes, and Roosevelt dimes.
The Barber dime was minted from 1892-1916. Created by Chief Engraver of the U.S. Mint, Charles Barber. The design features Lady Liberty’s profile on the obverse, and the reverse shows a wreath and the denomination “one dime”.
The Mercury dime was minted from 1916-1945. This dime was designed by Adolph Weinman, and is actually a representation of Liberty wearing a winged cap, though the similarity to the Roman god Mercury was enough to nickname it “the Mercury dime”.
And the Roosevelt dime was first minted in 1946. The Roosevelt dime was designed by John R. Sinnock to honor President Franklin D. Roosevelt, in part for his work in helping to found the National Foundation for Infantile Paralysis (later renamed the March of Dimes), which raised money to aid in polio research and victims of the disease.
What Quarters Are Made of Silver?
All quarters before 1965 were made of silver, so if you’ve got a quarter dated before then, it’s a safe bet to say it’s a silver quarter.
There were also some Bicentennial quarters made with silver (but not all), the Bicentennial quarters that are made of silver are the ones with an S mintmark (struck at the San Francisco Mint). These quarters were made with 40% silver
There are also silver Proof quarters that are made with 90% silver, but generally speaking these are quarters you would purchase in a set, and you’re unlikely to find them in circulation anywhere as they’re worth more than their face-value.
When Did They Stop Making Silver Coins?
Production of silver coins ended in the year 1965, when the mint switched the composition of quarters, dimes, and half dollars to a copper-nickel alloy, which is still used in coins to this day.
Collectors aren't a big fan of the new compositions but that doesn't mean there aren't still valuable or rare coins being produced today!
Are Silver Dimes and Quarters Valuable?
While they do inherently hold more value than modern coinage, the value of silver dimes and quarters isn’t always much. You can probably get close to the intrinsic value of the silver for a silver quarter or dime, though there are some coins that are worth more because of scarcity, rarity, age, and other numismatic values. Currently (at the time of publishing) the spot price of silver is at about 24.06, if you multiply that by the silver weight of a dime, which is 0.07234 troy ounce, you’ll get the melt value of your dime, which in this case would be $1.74. If you had a good size collection of silver dimes, that would be a good chunk of change!

Top 10 Rare Error Coins
Among the many error coins, some stand out for their rarity and the stories behind their creation. Here are ten of the most valuable:
- 1943 Bronze Lincoln Cent: Mistakenly struck in bronze instead of the usual zinc-coated steel during wartime shortages.
- 1955 Double Die Lincoln Cent: Famous for its clear doubling of inscriptions and date.
- 1972 Double Die Obverse Lincoln Cent: This coin features dramatic doubling on its obverse, making it a collector's favorite.
- 2000 Sacagawea Dollar Coin/Quarter Mule: A rare mule coin with a Sacagawea reverse and a state quarter obverse.
- 1969-S Double Die Obverse Lincoln Cent: Known for its strong and obvious doubling, this coin is highly prized.
- 1982 No Mint Mark Roosevelt Dime: These dimes accidentally left the Philadelphia mint without a mint mark.
- 1918/7-S Standing Liberty Quarter: A rare overdate error where a 1918 quarter was struck over a 1917 die.
- 1942/1 Mercury Dime: Another overdate, with a 1942 die struck over a 1941 die, available from both Philadelphia and Denver mints.
- 1937-D 3-Legged Buffalo Nickel: This error was caused by a die abrasion that removed one of the buffalo's legs.
- 1922 Plain Lincoln Cent: Due to die polishing, these cents came out missing the "D" mint mark.
