If you have ever inherited a coffee can full of old dimes and quarters, or picked up a bag of worn silver coinage at a show, the first question is always the same: what is this actually worth? "Junk silver" — circulated U.S. coins that trade for the silver they contain — is priced almost entirely on its melt value. That sounds simple, but getting the number right means knowing your coin compositions, checking for hidden collector premiums, and doing a little arithmetic with the live silver price.
Step One: Rule Out Collector Value
Before you treat any coin as mere metal, look for numismatic value. A coin's worth is driven by its condition, mintage, rarity, and what buyers will pay — and coins with real collector demand can sell for far more than their silver content alone. The classic examples are Morgan and Peace dollars: never toss these into the melt pile without checking their date, mint mark, and grade first. A few minutes of research can be the difference between melt money and a genuinely valuable sale.
Step Two: Sort by Silver Composition
U.S. junk silver comes in three compositions, and each has its own silver content — so separating them is the essential organizing step:
- 90% silver (.900 fine): dimes, quarters, half dollars, and dollar coins dated 1964 or earlier. These are the backbone of most junk-silver collections.
- 40% silver: Kennedy half dollars dated 1965–1970 (plus the special 1976 bicentennial issues), and Eisenhower "Ike" dollars dated 1971–1974 and 1976.
- 35% silver: wartime Jefferson nickels dated 1942–1945. Nickel was conserved for armored military equipment during World War II, so these coins were struck in an alloy substituting silver and manganese.
The Melt-Value Formulas
Once sorted, a coin's melt value is simply the current silver spot price multiplied by the coin's actual silver weight. Because compositions and coin weights differ, there is no single formula — each coin type has its own multiplier:
| Coin | Silver per coin (troy oz) | Melt-value formula |
|---|---|---|
| 90% half dollar | 0.3616 | Spot price × 0.3616 |
| 90% quarter | 0.1808 | Spot price × 0.1808 |
| 90% dime | 0.07238 | Spot price × 0.07238 |
| 40% Eisenhower dollar | 0.3161 | Spot price × 0.3161 |
| 40% half dollar | 0.15 | Spot price × 0.15 |
| 35% war nickel | 0.057 | Spot price × 0.057 |
For example, if silver is trading at $30 an ounce, a single 90% half dollar holds about $10.85 worth of silver (30 × 0.3616), while a war nickel holds about $1.71 (30 × 0.057). Add up the quantities you own in each category and you have your collection's total melt value.
One reality check: when you sell, expect offers slightly below melt value. Dealers and buyers need their margin, so the number you calculate is the ceiling, not the checkout price.
Buying Junk Silver Wisely
If your main interest is silver content rather than collecting, junk silver is one of the cheapest ways to own the metal — and a few tactics keep it cheaper still. Cull or damaged coins typically carry slightly lower premiums than nicer pieces, so ask for them. For larger purchases, bags sold by face value can be excellent value, since the premium per ounce of silver drops as the bag size grows. Whatever you buy, run the math yourself: divide the price by the actual silver content to see what you are really paying per ounce, and compare that against current spot before committing.
