What Junk Silver Is
“Junk silver” refers to pre-1965 US coins that contain 90% silver and carry no numismatic premium above their melt value. The term is a misnomer; there is nothing junk about them. These are Mercury dimes, Roosevelt dimes, Washington quarters, Walking Liberty half dollars, Franklin half dollars, and Kennedy half dollars (1964 only for 90% content) that circulated as everyday currency when US coinage was still backed by silver.
The US Mint switched to copper-nickel clad coinage in 1965, ending an era of circulating silver. What remains is a finite, shrinking supply of constitutional silver that trades based on silver content rather than collector value. Worn, dateless, common-date coins in average circulated condition, sold in bags by face value.
Why Stackers Buy Junk Silver
Three characteristics set constitutional silver apart from modern bullion products.
Low to zero premium. In normal markets, junk silver trades near melt value, sometimes at or even below melt value. Compare that to American Silver Eagles at $3-6 over spot or silver rounds at $1-3 over spot. For raw ounces-per-dollar, junk silver is often the cheapest silver available.
Universal recognition. Everyone in the US recognizes a quarter or a dime. In a barter or emergency scenario (a common consideration among stackers), a recognizable pre-1965 quarter does not require assay or explanation. Its silver content is established by law and widely known.
Built-in divisibility. A single ounce of silver is often too large a unit for small transactions. Junk silver breaks naturally into smaller units: a dime contains approximately 0.0723 oz of silver, a quarter about 0.1808 oz, a half dollar about 0.3617 oz. No cutting required.
Coin Types and Silver Content
All 90% silver US coins contain the same ratio: 90% silver, 10% copper, with a slight weight reduction from wear in circulated examples.
Dimes (90% Silver)
Mercury Dime (1916-1945): The “Mercury” is actually a depiction of Liberty wearing a winged cap. These are the older dimes in the junk silver market. Weight: 2.50 grams when new, containing 0.0723 oz of silver. Circulated examples may weigh slightly less due to wear.
Roosevelt Dime (1946-1964): More commonly found in junk silver bags due to later production dates. Same weight and silver content as Mercury dimes. The 1964 Roosevelt is the last year of 90% silver dimes.
Quarters (90% Silver)
Washington Quarter (1932-1964): Weight: 6.25 grams when new, containing 0.1808 oz of silver. The most commonly encountered denomination in junk silver. Easy to count and stack; $1 face value (4 quarters) contains approximately 0.7234 oz of silver.
Half Dollars (90% Silver)
Walking Liberty Half Dollar (1916-1947): Adolph Weinman’s iconic design, the same one later adapted for the Silver Eagle. Weight: 12.50 grams, containing 0.3617 oz of silver. Walking Liberties in better condition can carry mild numismatic premiums; heavily worn examples trade as junk.
Franklin Half Dollar (1948-1963): Benjamin Franklin on the obverse, Liberty Bell on the reverse. Same weight and silver content as Walking Liberty halves. Less collector interest means nearly all circulated examples trade as junk silver.
1964 Kennedy Half Dollar: The only Kennedy half with 90% silver content. Weight: 12.50 grams, 0.3617 oz silver. The 1964 date is common (over 430 million minted across Philadelphia and Denver) and trades at junk silver premiums.
40% Silver Half Dollars (1965-1970)
Kennedy half dollars from 1965-1970 contain 40% silver (silver-clad), weighing 11.50 grams with approximately 0.1479 oz of silver per coin. These trade at a discount to 90% junk silver on a per-ounce basis and are less popular among stackers due to the lower silver content. However, they often trade near or at melt value, making them a cheap way to accumulate silver.
$1 face value of 40% halves contains approximately 0.2958 oz of silver versus 0.7234 oz for 90% coins. The math works only if the price per ounce of actual silver content is competitive.
How to Calculate Silver Content
The standard reference point is $1.00 face value of 90% silver coinage.
$1.00 face value = approximately 0.7234 troy ounces of silver (when new)
Wear reduces this slightly. The industry convention for circulated junk silver uses 0.715 oz per $1 face value as a working estimate, sometimes rounded to 0.72.
| Face Value | Silver Content (worn) | Silver Content (new) |
|---|---|---|
| $1.00 | ~0.715 oz | 0.7234 oz |
| $10.00 | ~7.15 oz | 7.234 oz |
| $100.00 | ~71.5 oz | 72.34 oz |
| $1,000.00 (bag) | ~715 oz | 723.4 oz |
To calculate the melt value of a bag: multiply face value by 0.715, then multiply by the current spot price. A $100 face value bag at $30 spot silver is worth approximately $100 x 0.715 x $30 = $2,145 in silver content.
How Junk Silver Is Priced
Junk silver is quoted as a multiplier of face value. If the market price is “22x face,” a $1 face value lot costs $22.00. A $100 face value bag costs $2,200.
To evaluate whether a price is fair, compare the effective per-ounce cost to spot. Using the 22x face example: $22 / 0.715 oz = $30.77 per ounce of silver. If spot is $30.00, the effective premium is $0.77/oz or about 2.6%. That is competitive with the cheapest silver bars.
The multiplier fluctuates with silver prices and market conditions. In periods of strong demand, the multiplier can reflect a premium over melt. In slower markets, it sometimes dips to melt value or slightly below, as dealers acquire bags cheaply from estate liquidations and sellers who are not tracking spot prices closely.
Buying Junk Silver
Standard Quantities
$1 face value: The minimum lot at many dealers. Contains roughly 0.715 oz of silver. A low-commitment entry point.
$10 face value: A common purchase increment. Roughly 7.15 oz of silver. Often sold as a random mix of denominations or as a specific denomination (e.g., “$10 face in Washington quarters”).
$100 face value (half bag): Roughly 71.5 oz of silver. A canvas bag or heavy ziplock. This is where volume pricing begins to improve.
$1,000 face value (full bag): The institutional standard. Roughly 715 oz of silver in a sealed canvas bag. Weighs approximately 55 pounds. Full bags often trade at the tightest premiums to melt value. Not practical for casual buyers but standard in the wholesale market.
Where to Buy
Major online dealers carry junk silver in all denominations and quantities. Local coin shops often have the best prices on junk silver because they acquire it from walk-ins and estates. The r/PMsForSale community on Reddit is an active secondary market where junk silver trades frequently.
When buying mixed lots, verify you are getting 90% silver, not 40% Kennedy halves mixed in. Reputable dealers separate these clearly. Private sellers may not.
Junk Silver vs Modern Bullion
| Factor | Junk Silver (90%) | Silver Rounds (.999) | Silver Eagles (.999) |
|---|---|---|---|
| Premium over spot | 0-5% | 5-12% | 10-20% |
| Recognition | Universal in US | Moderate | Very high |
| Divisibility | Excellent | Single unit | Single unit |
| Purity | 90% | 99.9% | 99.9% |
| Storage efficiency | Poor (varied sizes) | Good | Good |
| Supply | Finite, declining | Unlimited production | Mint-limited |
The storage efficiency disadvantage is real. A $1,000 face value bag of junk silver contains roughly 715 oz of silver but weighs about 55 pounds and takes up significant space. The same 715 oz in 100 oz bars would be more compact and organized. This matters at scale.
Junk silver’s finite supply is worth noting. No new 90% silver coins are being produced. Coins are continuously removed from the market through melting, loss, and collector absorption. The available supply shrinks over time, which provides a floor under premiums long-term.
Sorting and Grading
For investment purposes, detailed grading is unnecessary. Junk silver is junk silver; it trades by weight, not by condition. However, keep an eye out for coins with residual numismatic value.
Key dates and mint marks worth pulling from junk lots: 1916-D Mercury dime, 1921 and 1921-D Walking Liberty halves, and any coin in unusually high grade for a junk lot. These can be worth multiples of melt value. A $5 magnifying glass and basic knowledge of key dates can pay for itself quickly.
Most coins in junk bags are common dates in average circulated condition, worth exactly their silver content and nothing more. That is the point and the appeal.
Building a Junk Silver Position
A practical approach is to accumulate junk silver as a component of a broader physical silver strategy. Many stackers allocate 20-30% of their silver budget to constitutional silver and the remainder to bars and rounds for cost-efficient weight accumulation.
Start with $10-20 face value to familiarize yourself with the coins, their feel, and their silver content. Then scale up to $100 face value (approximately 71.5 oz) as a core holding. Beyond $500 face value, storage becomes a practical consideration given the weight (roughly 28 pounds per $500 face).
For tracking purposes, record purchases by face value, price paid per $1 face, and the resulting effective price per ounce of silver content. This simplifies tax basis calculations when selling.
Frequently Asked Questions
What is the best junk silver coin to buy?
Washington quarters offer the best balance of silver content per coin, countability, and availability. Half dollars contain more silver per coin (0.36 oz vs 0.18 oz) but are bulkier. Dimes (0.07 oz each) provide the finest divisibility. Most stackers buy whatever denomination offers the lowest premium per ounce at the time of purchase.
Is junk silver a good investment?
Junk silver provides silver exposure at the lowest premiums available. Its finite supply, universal recognition, and divisibility make it a favorite among precious metals stackers. As a silver investment, it tracks the silver price like any other form of the metal. See the silver investing guide for the broader investment case.
How can I tell if a coin is 90% silver?
US dimes, quarters, and half dollars dated 1964 or earlier are 90% silver. Look at the edge: silver coins have a solid silver edge, while clad coins show a copper stripe. The date is the simplest indicator. Kennedy halves from 1965-1970 are 40% silver (silver edge visible but with a slight copper tint). 1971 and later are copper-nickel clad with no silver content.
Where can I sell junk silver?
Local coin shops buy junk silver readily, typically at 90-95% of melt value. Online dealers offer buyback programs. The r/PMsForSale community allows peer-to-peer sales near melt. Selling in $10 or $100 face value increments is most practical. See the selling silver guide for detailed strategies.
Does junk silver tarnish?
Circulated junk silver is already toned and worn. Further tarnishing is minimal and irrelevant to trade value. Unlike pristine bullion coins, junk silver is valued solely for silver content. Appearance does not affect price. Store however is convenient; no special preservation measures are needed.
