Junk Silver Explained: What Pre-1965 90% Silver Coins Actually Contain

Junk silver is the trade name for worn U.S. dimes, quarters and half dollars minted in 1964 or earlier. These coins are 90% silver, and because they're too common or too worn to interest collectors, they trade for their metal. Dealers price them by face value, and the silver content per dollar of face is fixed by the coins' original specifications, so the math is easy once you know it.

The word "junk" isn't an insult. It just means nobody is paying extra for the date or condition. That's the appeal: you're buying silver in small, recognizable, government-minted pieces.

Which coins count as junk silver

The cutoff is the Coinage Act of 1965, which President Lyndon Johnson signed on July 23, 1965. It removed silver from the circulating dime and quarter and cut the half dollar from 90% to 40% silver. The U.S. Mint's own history pages confirm that silver came out of the dime in 1965 and out of the half dollar entirely in 1971, when both became copper-nickel clad.

That gives you three groups to keep straight:

• 90% silver: dimes, quarters and half dollars dated 1964 and earlier. This is what "junk silver" means in a dealer listing.
• 40% silver: Kennedy half dollars dated 1965 through 1970. These are sold separately, at a lower silver content per coin.
• No silver: dimes and quarters dated 1965 and later, and circulation half dollars from 1971 on.

Two other categories sometimes get lumped in. Pre-1965 silver dollars (Morgan and Peace designs) are also 90% silver, but they usually sell at their own prices because collectors care about them. Wartime nickels, made from 1942 to 1945, are 35% silver and trade as their own niche.

The silver content math

Each 90% coin was made to a set weight. A dime weighs 2.50 grams, a Washington quarter 6.25 grams, and a 1964 Kennedy or a Franklin half 12.50 grams. Multiply by 0.90 for the silver, then divide by 31.1035 (grams per troy ounce) to get actual silver weight, often abbreviated ASW.

Notice the pattern in the first three rows. Ten dimes, four quarters or two halves all weigh 25 grams, because the Mint kept the silver coinage proportional to face value. So $1 of face value in any mix of 90% dimes, quarters and halves holds 22.5 grams of silver, or about 0.7234 troy ounces.

Why dealers use 0.715, not 0.723

Coins that spent decades in circulation lost a little metal to wear. The industry convention is to rate circulated 90% silver at about 715 troy ounces per $1,000 face value, or 0.715 oz per dollar, instead of the 723 oz an unworn bag would hold. APMEX and JM Bullion both describe their $1,000 face bags as containing approximately 715 oz of silver.

That 0.715 figure is the number to use when you compare a junk silver price against other silver. If a dealer quotes a price per $1 face value, divide it by 0.715 to get the effective price per ounce of silver, then compare that to what the same dealer charges for a one-ounce round or coin.

A quick worked example

Say you're looking at $10 face value. That's 100 dimes, 40 quarters or 20 halves. At 0.715 oz per dollar, it holds about 7.15 troy ounces of silver. If the dealer's price for that $10 face lot, divided by 7.15, comes out close to what they charge per ounce for generic rounds, you're paying a similar premium. If it's well above, you're paying for the convenience of small coins.

40% halves need separate math

A 1965–1970 Kennedy half holds about 0.1479 oz of silver, so $1 face in 40% halves (two coins) holds about 0.296 oz, less than half of what 90% coins carry. Listings usually separate these, but if a seller lumps them into a "silver halves" lot, ask for the date breakdown.

How junk silver is packaged and sold

Dealers sell 90% silver by face value in lots ranging from a few dollars to full bags. The classic unit is the $1,000 face value bag. APMEX's listing says its $1,000 bags hold a single denomination of its choosing, with dates of 1964 and earlier depending on stock on hand. JM Bullion says its bag contents depend on inventory and the coins come in various degrees of condition, and that a $1,000 order may ship as two $500 face bags in separate packages.

A few practical points follow from that:

• You usually can't pick denominations. If you want only dimes for small-unit flexibility, look for a listing that specifies dimes.
• Condition varies. Expect anything from heavily worn to fairly sharp coins. The silver rating already assumes wear.
• It's heavy. $1,000 face of 90% coins weighs 25 kilograms, roughly 55 pounds, by the 25-grams-per-dollar math. Plan storage accordingly.

Premiums move around

Junk silver has no fixed premium. It sometimes sells near the spot price of its silver content and sometimes well above it, depending on supply of old coins and how many buyers want small units at that moment. Don't assume it's always the cheapest way to hold silver. Run the per-ounce math against rounds and bars on the same day.

Why people buy it (and the trade-offs)

Junk silver has a few real advantages over newer bullion, and a few drawbacks worth knowing before you buy.

Advantages

• Small units. A dime holds about 0.07 oz of silver. If you ever want to sell or trade a small amount, you don't have to break up a 10-ounce bar.
• Easy to recognize. U.S. coins with known weights and designs are familiar to any coin shop, which makes them simpler to authenticate than an unfamiliar private-mint bar.
• No collector premium. Because it's sold for metal, you're not paying extra for rarity you may never recover.

Drawbacks

• Lower purity. At 90% silver you carry copper weight you don't get paid for, so it takes more space per ounce than .999 bullion.
• Counting and weighing. Selling a big bag means a dealer will weigh or count it, and worn coins can come up a little light against the 0.715 rating.
• Variable premium. When demand spikes, small coins can get expensive relative to bars.

Selling junk silver

Most dealers and coin shops buy 90% silver, and they quote it the same way they sell it: per $1 face value. Get two or three bids and convert each to a per-ounce price using 0.715 so you're comparing like with like.

Before selling, pull out anything that might be worth more than melt. Key dates, mint errors and coins in unusually good condition can carry collector value. If a coin looks barely worn, it's worth having a coin shop take a look before it goes into a melt-priced lot.

Reporting thresholds

Dealers file Form 1099-B on certain customer sales. JM Bullion's tax guide lists 90% silver U.S. coins as reportable when dimes, quarters and half dollars together exceed $1,000 in face value in a transaction. Reporting or not, gains on precious metals are generally taxable; our guide to IRS reporting rules covers the details, and a tax professional can tell you how it applies to you.

What to do next

1. Decide if small units matter to you. If you want silver you can split into small amounts, junk silver fits. If you just want the most silver per dollar and per inch of shelf space, compare .999 rounds and bars first.
2. Convert every quote to a per-ounce price. Divide the price per $1 face by 0.715. Compare that with the same dealer's one-ounce prices on the same day.
3. Confirm what's in the lot. Check whether it's 90% or 40% coins, which denominations, and whether the face value is exact.
4. Check payment and shipping costs. Many dealers charge less for check or wire than for cards, and shipping on a heavy bag adds up if you're under a free-shipping threshold.
5. Plan storage before it arrives. A full bag weighs about 55 pounds. See our storage options guide for safes, safe-deposit boxes and vaults.

Junk silver isn't magic and it isn't a bargain by default. It's 90% silver in small, familiar pieces, and its value comes down to the silver math in the table above.
