Quick answer: Pre-1965 US dimes, quarters, and half dollars are 90 percent silver by weight. Each one dollar of face value in that subsidiary coinage holds about 0.7234 troy ounces of silver when uncirculated, or closer to 0.715 troy ounces once normal wear is counted. Multiply that weight by the day's silver spot price for melt value.
Short on time? The essentials
- US dimes, quarters, and half dollars struck for circulation before 1965 share a single silver standard set by the Coinage Act of 1873 and confirmed through the Coinage Act of 1965. Each coin is 90 percent silver and 10 percent copper by weight.
- A pre-1965 Roosevelt or Mercury dime weighs 2.50 grams and holds 0.07234 troy ounces of silver. A Washington, Standing Liberty, or Barber quarter weighs 6.25 grams and holds 0.1808 troy ounces. A Kennedy 1964, Franklin, Walking Liberty, or Barber half weighs 12.50 grams and holds 0.3617 troy ounces.
- The 90 percent standard is proportional across the three subsidiary denominations. Ten dimes, four quarters, or two halves all sum to 25.00 grams of coin, 22.50 grams of silver, and about 0.7234 troy ounces per one dollar of face value in an uncirculated state.
- Well-worn "junk silver" is typically priced at about 0.715 troy ounces per one dollar of face value. That figure builds in a small wear allowance because circulated coins lose measurable mass over decades of handling.
- A standard bag of 1,000 dollars of face value in 90 percent silver holds about 715 troy ounces of silver at the industry buying convention, or 723.4 troy ounces at the uncirculated theoretical figure.
- Morgan and Peace silver dollars sit on a separate weight standard. Each coin weighs 26.73 grams and holds 0.7734 troy ounces of silver, higher than a full dollar of face value paid in dimes, quarters, or halves.
- The Coinage Act of 1965, Public Law 89-81, was signed by President Lyndon Johnson on July 23, 1965. It removed silver from the dime and quarter and cut the Kennedy half from 90 to 40 percent silver for the 1965 through 1970 issues.
- Melt value equals actual silver weight in troy ounces multiplied by the day's silver spot price. Any "melt calculator" runs the same arithmetic. Face value is irrelevant to the silver figure and is only worth spending as legal tender in the very rare case that silver falls below face.
- Common-date circulated 90 percent coins trade close to melt with a modest bullion premium. Key dates, rare mint marks, high-grade uncirculated pieces, and problem-free type coins carry stronger collector demand and price above melt at coin dealers rather than bullion houses.
- These coins are not eligible for a self-directed precious metals IRA. Silver held for retirement is a different topic, covered in our silver IRA fineness explainer.
Millions of Americans still hold pre-1965 dimes, quarters, and half dollars in a coffee can, a safe deposit box, or an inherited coin album. The common question is a simple one. What is the pile actually worth today, and how do the numbers add up if the coins are sold as silver rather than spent as change.
This page answers that question with a single set of verified weights and one repeatable formula. It covers what "90 percent silver" means, how much silver each coin holds, why circulated pieces run a shade under the textbook figure, and how to price a stack against an example silver spot price. Silver dollars are handled separately because they sit on their own weight standard.
Which US coins are 90 percent silver
The 90 percent silver standard for United States subsidiary coinage was set by the Coinage Act of 1873 and stayed in place for the dime, quarter, and half dollar until the mid 1960s. Every coin struck for circulation in those three denominations before 1965 shares the same alloy of 90 percent silver and 10 percent copper by weight.
Series inside the 90 percent silver family for the dime include the Seated Liberty dime through 1891, the Barber dime from 1892 through 1916, the Mercury dime from 1916 through 1945, and the Roosevelt dime from 1946 through 1964. All four share the 2.50 gram weight standard.
The quarter series inside the 90 percent silver family cover the Seated Liberty quarter through 1891, the Barber quarter from 1892 through 1916, the Standing Liberty quarter from 1916 through 1930, and the Washington quarter from 1932 through 1964. All four share the 6.25 gram weight standard.
The half dollar family includes the Seated Liberty half through 1891, the Barber half from 1892 through 1915, the Walking Liberty half from 1916 through 1947, the Franklin half from 1948 through 1963, and the Kennedy half of 1964. All five share the 12.50 gram weight standard. From 1965 forward the Kennedy half moved to a 40 percent silver clad composition, and from 1971 forward to copper nickel with no silver.
Silver content per coin, by denomination
The alloy math is direct. Multiply the total coin weight by 0.90 to get the mass of pure silver, then divide by 31.1035 grams per troy ounce to convert to the actual silver weight used by refiners and dealers.
A 90 percent silver dime weighs 2.50 grams total. Silver content is 2.25 grams, which converts to 0.07234 troy ounces of silver per coin. That figure applies identically to the Roosevelt dimes of 1946 through 1964, the Mercury dimes, the Barber dimes, and the Seated Liberty dimes.
A 90 percent silver quarter weighs 6.25 grams total. Silver content is 5.625 grams, which converts to 0.1808 troy ounces of silver per coin. The figure covers pre-1965 Washington quarters, Standing Liberty quarters, Barber quarters, and Seated Liberty quarters.
A 90 percent silver half dollar weighs 12.50 grams total. Silver content is 11.25 grams, which converts to 0.3617 troy ounces of silver per coin. The figure covers the 1964 Kennedy half, Franklin halves, Walking Liberty halves, Barber halves, and Seated Liberty halves.
The 0.7234 troy ounces per dollar of face value rule
The three subsidiary denominations were struck in proportion by design. Ten dimes, four quarters, or two halves each sum to a total coin weight of exactly 25.00 grams for one dollar of face value. Multiplied by 90 percent silver, the pure silver content is 22.50 grams per dollar of face.
Twenty two and a half grams divided by 31.1035 grams per troy ounce gives 0.7234 troy ounces of silver for every one dollar of face value in an uncirculated coin. The figure is the textbook constant behind every published "junk silver" quote, and it holds across any mix of the three denominations.
The 0.7234 figure is often shortened to a round rule of thumb. One thousand dollars of face value in an uncirculated pre-1965 90 percent silver mix holds about 723.4 troy ounces of silver. That figure is the theoretical maximum before the wear allowance discussed in the next section.
Why circulated coins run under the theoretical weight
Silver coins circulating for decades in cash registers and pockets lose a small but measurable amount of mass to friction and handling. The rims wear, the design details soften, and the coin weighs slightly less than a freshly struck example from the same die. Dealers price the loss with a standard wear allowance.
The industry buying convention for well-circulated 90 percent silver bags is 0.715 troy ounces of silver per one dollar of face value. That figure is about 1.2 percent below the 0.7234 theoretical maximum, roughly the average mass loss for a mixed bag pulled from long circulation. A thousand dollar face bag priced at that convention holds about 715 troy ounces of silver.
Uncirculated rolls, sealed mint sets, and coins that spent their lives in a collection tend to be priced at the full 0.7234 figure because they show minimal wear. Well-worn coins sourced from decades in circulation are priced closer to 0.715. Some large refiners publish an even more conservative 0.7150 figure for smelting settlement, absorbing the last fraction of variance.
Bag composition matters. A bag that skews heavily to worn Barber dimes and Barber quarters weighs slightly less per dollar of face than a bag of nearly new 1964 Kennedy halves and 1964 Roosevelt dimes. Any credible buyer will disclose which convention they use before quoting a bag purchase price.
Why 1964 was the last year for 90 percent silver dimes and quarters
The 90 percent silver era ended by an act of Congress rather than an industry decision. The Coinage Act of 1965, Public Law 89-81, cleared Congress in the summer of 1965 and was signed by President Lyndon Johnson on July 23 of that year. The law removed silver from the dime and quarter entirely and cut the half dollar's silver content from 90 to 40 percent (source: Coinage Act of 1965 legislative summary).
The driver was operational, not investment-related. Rising silver prices in the early 1960s had pushed the Mint's cost per coin close to the metal value of the finished piece, and the Treasury was watching 90 percent silver dimes and quarters disappear from circulation into private hoards. The Coinage Act was written to keep small change in circulation without a metal shortage.
Silver stayed in the half dollar for a shorter window than most savers realize. The Kennedy half was struck at 40 percent silver clad from 1965 through 1970, then converted to copper nickel clad starting with the 1971 date. Silver returned only in special collector sets after 1992, never in coins meant for change.
Silver dollars, a separate weight standard
Morgan and Peace silver dollars are 90 percent silver by alloy, but they do not follow the 25.00 grams per dollar rule that governs dimes, quarters, and halves. Each Morgan or Peace dollar weighs 26.73 grams total, holds 24.057 grams of pure silver, and carries an actual silver weight of 0.7734 troy ounces per coin (source: Morgan dollar composition; Peace dollar composition).
The higher silver content per dollar of face reflects the coin's history as a standalone monetary unit rather than as a subsidiary of a paper dollar. A Morgan or Peace dollar contains 412.5 grains of standard silver, roughly 3.9 percent more silver per dollar of face than the 371.25 grains in one dollar of subsidiary coinage.
Trade dollars, Bust dollars, and Seated Liberty dollars have their own weight standards and are almost always priced as numismatic pieces rather than as bullion. Anyone melting or selling silver dollars should verify the specific series before applying a rule of thumb, because the differences show up quickly in a large stack.
The practical rule for a mixed pile is to separate silver dollars from dimes, quarters, and halves before running melt math. Price the silver dollar group at 0.7734 troy ounces per coin. Price the dime, quarter, and half group at 0.7234 troy ounces per dollar of face value, or at 0.715 if the pieces are well-worn.
Silver content and illustrative melt table
The table below rolls up the actual silver weight for each 90 percent silver denomination and computes an illustrative melt value at three example silver spot prices. Real spot prices move continuously during market hours, so the dollar figures below are computations from stated example prices, not live quotes.
| Denomination | Coin weight | Silver weight | At 20 dollars per ounce | At 30 dollars per ounce | At 40 dollars per ounce |
|---|---|---|---|---|---|
| Pre-1965 dime (Roosevelt, Mercury, Barber, Seated) | 2.50 grams | 0.07234 troy ounces | 1.45 dollars | 2.17 dollars | 2.89 dollars |
| Pre-1965 quarter (Washington, Standing Liberty, Barber, Seated) | 6.25 grams | 0.1808 troy ounces | 3.62 dollars | 5.42 dollars | 7.23 dollars |
| Pre-1965 half dollar (Kennedy 1964, Franklin, Walking Liberty, Barber, Seated) | 12.50 grams | 0.3617 troy ounces | 7.23 dollars | 10.85 dollars | 14.47 dollars |
| Morgan or Peace silver dollar | 26.73 grams | 0.7734 troy ounces | 15.47 dollars | 23.20 dollars | 30.94 dollars |
| One dollar of face value in dimes, quarters, or halves (uncirculated) | 25.00 grams | 0.7234 troy ounces | 14.47 dollars | 21.70 dollars | 28.94 dollars |
| One dollar of face value in dimes, quarters, or halves (well-worn convention) | Under 25.00 grams | 0.715 troy ounces | 14.30 dollars | 21.45 dollars | 28.60 dollars |

The melt math, priced against example spot prices
Melt value is a computation, not a quote. It equals a coin's actual silver weight in troy ounces multiplied by the day's silver spot price. Any online "melt calculator" runs the same arithmetic and updates with each spot price tick.
The chart below shows the illustrative melt value of one dollar of face value in pre-1965 dimes, quarters, or halves, plus a single Morgan or Peace dollar, computed at three example silver spot prices. The 90 percent subsidiary coinage figure uses the uncirculated 0.7234 troy ounces per dollar constant. The Morgan or Peace dollar figure uses the 0.7734 per coin figure.
To price a specific pile against the live market on a given day, replace the example spot price with a public quote and rerun the multiplication. Multiply the total face value in dimes, quarters, or halves by 0.7234 for the uncirculated figure, or by 0.715 for the well-worn figure. Multiply the count of silver dollars by 0.7734.
Add the two subtotals. Multiply the combined troy ounce figure by the day's silver spot price. The result is the melt value of the pile.
A worked example on a bag of junk silver
Coin shops often price 90 percent silver in "bags" or partial bags because the coins have been traded that way for decades. A standard bag is 1,000 dollars of face value, roughly 55 pounds of coin, and a common trading unit is a "half bag" at 500 dollars face or a "tenth bag" at 100 dollars face.
Picture a retiree who inherits a small canvas coin bag from a parent. Sorted on the kitchen table, the bag holds 200 pre-1965 Washington quarters (50 dollars face), 400 pre-1965 Roosevelt dimes (40 dollars face), and 20 pre-1965 Franklin halves (10 dollars face). Total face value: 100 dollars. All coins show honest circulation wear.
- Silver content by convention for well-worn subsidiary coinage: 0.715 troy ounces of silver per one dollar of face value.
- Total silver content of the 100 dollar face bag: 0.715 multiplied by 100 equals 71.5 troy ounces of silver.
- Illustrative silver spot price for the example: 30 dollars per troy ounce.
- Illustrative melt value of the bag: 71.5 troy ounces multiplied by 30 dollars per ounce equals 2,145.00 dollars in silver content per 100 dollar face bag. Real dealer buy price is a few percentage points below pure melt because dealers take a spread on the transaction.
- Illustrative sale figure at a modest melt spread, assuming a bullion dealer pays 95 percent of melt: 0.95 multiplied by 2,145.00 equals 2,037.75 dollars. Real spreads vary by dealer, region, and volume. Local coin shops typically pay a wider spread than online bullion houses on smaller lots.
Substitute a different spot price to reprice the same bag. At 25 dollars per ounce, the melt is 71.5 multiplied by 25, or 1,787.50 dollars. At 35 dollars per ounce, the melt is 2,502.50 dollars. At 40 dollars per ounce, the melt is 2,860.00 dollars. The 100 dollar face value is only relevant if the seller ever decides to spend the coins as legal tender, which has not made financial sense at any recent silver price.

A full 1,000 dollar face bag scales the same way. At 0.715 troy ounces per dollar of face, a full bag holds 715 troy ounces of silver. At an illustrative 30 dollars per troy ounce, the melt value is 21,450 dollars. At the uncirculated convention of 0.7234, a full bag holds 723.4 troy ounces, worth 21,702 dollars at the same example spot price.
A five step check for any US silver coin
The steps below turn the general rules into a repeatable field check for any coin from a mixed pile of United States pocket change or an inherited album.
- Read the denomination and date on the coin. A dime, quarter, or half dollar with a date of 1964 or earlier is 90 percent silver by the pre-1965 subsidiary coinage standard. A dime or quarter with a date of 1965 or later is copper nickel clad with no silver. A Kennedy half with a date from 1965 through 1970 is 40 percent silver clad, not 90 percent. A Kennedy half dated 1971 or later for circulation is copper nickel with no silver.
- Inspect the edge for a copper stripe. Turn the coin so the reeded rim faces you. A 90 percent silver dime, quarter, or half dollar shows a solid silver-gray edge from face to face. A 1965 or later clad dime, quarter, or 1971 or later Kennedy half shows an obvious copper-brown stripe running around the middle of the edge, sandwiched between two thin silver-colored layers.
- Weigh the coin if the edge test is ambiguous. A jeweler's scale or kitchen scale that reads to the tenth of a gram is enough. A 90 percent silver dime weighs about 2.50 grams. A 90 percent silver quarter weighs about 6.25 grams. A 90 percent silver half dollar weighs about 12.50 grams. A Morgan or Peace silver dollar weighs about 26.73 grams. Clad replacements weigh less than the silver originals.
- Compute the actual silver weight for the pile. Multiply the number of 90 percent silver dimes by 0.07234 troy ounces. Multiply the number of 90 percent silver quarters by 0.1808 troy ounces. Multiply the number of 90 percent silver half dollars by 0.3617 troy ounces. Multiply the number of Morgan or Peace silver dollars by 0.7734 troy ounces. Add the four subtotals to reach the total actual silver weight in the pile.
- Multiply by an illustrative spot price to reach an illustrative melt figure. Look up a public silver spot quote in dollars per troy ounce. Multiply the pile's total actual silver weight by that spot figure. The result is the pile's melt value before any dealer spread. Add up dealer spread by contacting two or three buyers and comparing their offer against the same day's spot price.
Anyone comfortable with the five steps can sort a mixed jar of United States coinage into silver and non-silver piles in a single sitting. Pricing the silver pile only needs a calculator and a public silver spot quote.
Where a premium over melt actually appears
The default is that a well-worn common-date 90 percent silver dime, quarter, or half trades close to melt at a bullion dealer. Coin dealers and collectors do pay premiums over melt in specific situations, and it helps to know where those premiums live. Numismatic pricing shifts constantly, so the categories below are qualitative tiers rather than fixed dollar figures.
The first category is the recognized key date and semi-key date coins inside each series. A 1916-D Mercury dime, a 1932-D or 1932-S Washington quarter, or an 1893-S Morgan dollar carries strong collector demand well above the coin's silver content. Even in circulated grades, these dates trade at multiples of melt rather than as bullion.
The second category is uncirculated and near-uncirculated coins with original luster. A gem uncirculated 1963 Franklin half or a full band Mercury dime attracts collectors who pay for the surface preservation, not for the silver content. Certified holders from major grading services usually carry an added premium because the grade is documented.
The third category is scarce mint marks and low mintage issues that are not key dates but sit above the common run. The 1932-D Washington quarter and the 1949-S Franklin half both fall into this tier. So do certain Barber and Seated Liberty issues where surviving population is modest.
The fourth category is problem-free type coins. A common-date Morgan dollar in a clean uncirculated grade or a first-year 1948 Franklin half in bright original condition draws collector interest above melt because the coin serves as a representative example of the series in a type set.
Coins outside these categories are usually priced as bullion. That includes almost all worn common-date dimes, quarters, and halves from the last three decades of the 90 percent era. The Federal Trade Commission has published general consumer guidance on inflated pricing in coin sales pitched as rare investments (source: Federal Trade Commission, Investing in Bullion and Bullion Coins).
Limits and caveats to keep in mind
Every dollar figure on this page is a computation from a stated silver spot price, not a live quote from any specific dealer and not a forecast. Silver prices move continuously during market hours, and the number that fits a specific day belongs on that day only. The example spot prices of 20, 30, and 40 dollars per troy ounce are picked as clean round figures for arithmetic, not as predictions of future silver prices.
Dealer buy prices sit below melt by design. Any commercial buyer needs a spread on the transaction to cover assay, sorting, shipping, insurance, and profit margin. A single small pile of loose junk silver walked into a local coin shop usually sees a wider spread than a full sealed bag delivered to a bullion house. Sellers should call two or three buyers on the same day and compare offers before committing.
The 0.7234 and 0.715 conventions are averages, not exact figures for a specific bag. A bag heavily loaded with Barber dimes from the early 1900s weighs less per dollar of face than a bag of 1964 Kennedy halves in original rolls. Refiners and dealers weigh actual bags rather than trusting the theoretical figure alone on large transactions.
Face value and legal tender status do not affect melt. A pre-1965 90 percent silver dime remains legal tender at 10 cents, and a store is required to accept it as such. Spending the coin as legal tender has not made financial sense at any silver price seen since the 1960s, because the silver content alone runs many times the face value.
Collectible and numismatic premiums are qualitative on this page. Specific dollar figures for key dates, high grades, and certified coins depend on published price guides and completed auction sales. Anyone selling a large or unusual example should check current listings against completed sales on major public marketplaces before quoting a premium.
These coins are not eligible for a self-directed precious metals IRA. The Internal Revenue Code sets a silver fineness minimum well above the 90 percent alloy, and holding pre-1965 junk silver inside an IRA triggers a deemed distribution. Silver held for retirement follows a different rule set and is covered in our junk silver IRA eligibility explainer. The coins are fine to own personally, in any quantity, at any time.
90 percent silver coin questions, answered
Which US coins are 90 percent silver?
Every United States dime, quarter, and half dollar struck for circulation before 1965 is 90 percent silver and 10 percent copper by weight. That covers Seated Liberty, Barber, Mercury, Roosevelt (through 1964), Standing Liberty, Washington (through 1964), Walking Liberty, Franklin, and 1964 Kennedy. Morgan and Peace silver dollars are also 90 percent silver, on a separate weight standard.
How much silver is in a pre-1965 dime, quarter, and half dollar?
A 90 percent silver dime holds 0.07234 troy ounces of silver at a 2.50 gram coin weight. A 90 percent silver quarter holds 0.1808 troy ounces at 6.25 grams. A 90 percent silver half dollar holds 0.3617 troy ounces at 12.50 grams. The figures come from a direct alloy calculation and apply across every pre-1965 series in each denomination.
What is the 0.7234 troy ounces per dollar rule?
Ten dimes, four quarters, or two halves each sum to 25.00 grams of total coin weight for one dollar of face value. At 90 percent silver, that equals 22.50 grams of pure silver, which converts to 0.7234 troy ounces. The figure holds for any mix of the three subsidiary denominations in an uncirculated state. Well-worn coins are conventionally priced at 0.715 troy ounces per dollar of face.
What is a pre-1965 90 percent silver coin worth today?
The melt value equals the coin's actual silver weight multiplied by the day's silver spot price. At an illustrative 30 dollars per troy ounce, a 90 percent silver dime holds about 2.17 dollars in silver, a quarter about 5.42 dollars, a half dollar about 10.85 dollars, and a Morgan or Peace dollar about 23.20 dollars. Substitute the current spot price to reprice.
Are 1965 or later dimes and quarters silver at all?
No. The Coinage Act of 1965 removed silver from the dime and quarter starting with the 1965 date. Every circulating Roosevelt dime and Washington quarter dated 1965 or later is copper nickel clad and holds no silver. Special silver proof dimes and quarters from later sets exist, but only in Mint packages sold to collectors, never as pocket change.
How is a Morgan or Peace silver dollar different from a 90 percent junk silver bag?
Both are 90 percent silver by alloy, but the silver dollar sits on a heavier weight standard. Each Morgan or Peace dollar weighs 26.73 grams and holds 0.7734 troy ounces of silver. One dollar of face value in dimes, quarters, or halves weighs 25.00 grams and holds 0.7234 troy ounces. The silver dollar carries roughly 3.9 percent more silver per dollar of face than the subsidiary coinage.
Can I put pre-1965 90 percent silver coins in a precious metals IRA?
No. The Internal Revenue Code sets the fineness minimum for IRA silver at .999, referenced to the delivery standard of a regulated futures contract. A 90 percent silver coin sits far below that line. Holding the coins inside a self-directed IRA triggers a deemed distribution under IRC section 408(m). The coins can be held personally without restriction, but they cannot sit inside an IRA.
Is it better to sell 90 percent silver coins or to hold them?
That decision depends on personal cash needs, the current silver spot price, and the buyer's dealer spread. Selling makes sense if the seller needs the cash or wants to consolidate into a different silver product. Holding makes sense if the seller has time and storage space and prefers a physical silver position. The math is straightforward either way and rarely benefits from a hurried decision.
