“Junk silver” is the market term for ordinary U.S. dimes, quarters, and half dollars minted in 1964 or earlier, when circulating coinage was 90% silver. Despite the name, it isn't junk — it's widely traded bullion valued for its silver content, not collectibility. It trades by face value: $1.00 of face value contains about 0.715 troy ounces of silver by market convention, and it offers unmatched small-unit divisibility with instant U.S. recognizability.
Key takeaways
- Junk silver = circulated U.S. 90%-silver coinage: dimes, quarters, and half dollars dated 1964 and earlier (composition: 90% silver, 10% copper).
- Market convention values $1.00 face at ~0.715 troy oz of silver — slightly below the theoretical 0.7234 oz to account for circulation wear.
- It is bought and sold by face value — in rolls and bags ($100, $500, $1,000 face) — making the math simple once you know the 0.715 factor.
- Its strengths are divisibility (a dime is ~0.0715 oz of silver) and recognizability without assay; its weaknesses are bulk, wear variance, and premium swings.
- Premiums on junk silver move independently of other formats — sometimes below rounds, sometimes sharply above, depending on demand and supply of a fixed, shrinking stock.
What it is, precisely
Before the Coinage Act of 1965, ordinary U.S. dimes, quarters, and half dollars were struck in an alloy of 90% silver and 10% copper. Those coins are the “junk” of junk silver — a dealer’s term meaning no numismatic value: the coins are priced as metal, not as collectibles. (Kennedy half dollars from 1965–1970 are a special case at 40% silver and trade separately; war-era nickels at 35% are another niche.)
The face-value math
| Unit | Face value | Approx. silver content |
|---|---|---|
| One dime | $0.10 | ~0.0715 troy oz |
| One quarter | $0.25 | ~0.179 troy oz |
| One half dollar | $0.50 | ~0.358 troy oz |
| Roll of dimes ($5 face) | $5.00 | ~3.575 troy oz |
| $100 face bag | $100 | ~71.5 troy oz |
| $1,000 face bag | $1,000 | ~715 troy oz |
To evaluate any junk-silver offer: multiply face value by 0.715 for ounces, multiply by spot for melt value, and read the difference as the premium — the same habit you use everywhere else. Premium math →
The honest tradeoffs
For it: instant recognizability to any U.S. counterparty without assay equipment; the finest divisibility in physical silver (useful for selling in small increments); no counterfeiting economics at the single-coin level (faking a worn dime isn’t worth a forger’s time, though bulk bags still deserve reputable sourcing); and a fixed, slowly shrinking supply, since no more will ever be minted.
Against it: bulk and weight per dollar of value are the worst of any silver format; wear means actual content varies coin to coin (the 0.715 convention averages this, but heavily worn coins run lighter); sorting and counting are real labor at size; and premiums are volatile — in calm markets junk silver has traded near or below generic rounds, while in demand surges its premium has spiked well above sovereign coins. Check the current premium against alternatives on the day you buy rather than assuming it’s the “cheap” option.
How it’s bought and sold
Dealers sell junk silver by face value — typically rolls, quarter-bags, half-bags, and full $1,000-face bags — usually described by coin type. Halves often carry slightly higher premiums than dimes and quarters; some buyers pay it for fewer pieces per ounce, others deliberately prefer dimes for maximum divisibility. Buyback works the same way in reverse: quoted per dollar of face against the 0.715 convention. Dealer policies vary; the dealer-evaluation rubric applies unchanged.
Frequently asked questions
Is junk silver better than silver rounds or bars?
Neither is universally better. Junk silver wins on divisibility and no-assay recognizability; rounds and bars win on storage density, purity (.999 vs .900), and predictable content. Many buyers hold both. Compare premiums per ounce on the day you buy — the ranking changes with market conditions.
Why 0.715 ounces instead of the theoretical 0.7234?
Freshly minted, $1.00 face contained 0.7234 troy oz of silver. Decades of circulation wear removed metal, so the market settled on ~0.715 oz per dollar face as the trading convention for circulated coins. Uncirculated 90% coinage can trade closer to theoretical content.
Are 1965-and-later coins worth anything as silver?
Ordinary dimes and quarters from 1965 onward are copper-nickel clad and contain no silver. The exceptions: 1965–1970 Kennedy half dollars (40% silver) and certain modern silver proof coins — both trade as their own categories.
Do I owe taxes when I sell junk silver?
Tax treatment varies by jurisdiction and changes over time. Keep purchase records and consult a qualified tax professional in your jurisdiction — this site does not provide tax advice.
