How Much Silver Is in a U.S. Coin? Denominations, Dates, and Melt Value
Most familiar U.S. silver coins contain 90% silver: a pre-1965 dime has 0.07234 troy ounce, a quarter 0.18084, a half dollar 0.36169, and a classic Morgan or Peace dollar 0.77344. But dates and types decide the answer: many old-looking coins are copper-nickel, so verify denomination, year, and issue before calculating melt.

Silver content is a physical specification, not a judgment based on a coin's color, age, or face value. This guide covers the familiar U.S. circulation issues people most often encounter, along with a few important exceptions. For a broader date-screening guide, see What Years of U.S. Coins Are Silver.
Start with denomination, date, and type
The United States has issued silver coins across several eras, but the metal content changes by denomination and issue. The Coinage Act of 1792 established silver denominations including the half dime, dime, quarter, half dollar, and dollar. Later composition changes mean a date alone is only a first screen, especially for collector sets, commemoratives, and modern special issues.[1]
The table below uses original, full-weight specifications. "Actual silver weight" (ASW) means the fine-silver content in troy ounces, not the gross weight of the entire coin. The NGC melt-value reference lists these standard weights and compositions for common U.S. issues.[2]
Do not assume every old-looking coin is silver. A regular 1965-and-later dime or quarter is copper-nickel clad, and ordinary nickels are not silver. The current U.S. Mint specifications describe modern dimes, quarters, and half dollars as clad coins, while the current nickel is a copper-nickel alloy.[3]
U.S. silver coin content by denomination and date
| Coin or series | Common qualifying dates or type | Fineness | Original gross weight | Actual silver weight |
|---|---|---|---|---|
| Barber, Mercury, and Roosevelt dime | Barber 1892-1916; Mercury 1916-1945; Roosevelt 1946-1964 | .900 | 2.50 g | 0.07234 troy oz |
| Barber, Standing Liberty, and Washington quarter | Barber 1892-1916; Standing Liberty 1916-1930; Washington 1932-1964 | .900 | 6.25 g | 0.18084 troy oz |
| Barber, Walking Liberty, Franklin, and 1964 Kennedy half dollar | Barber 1892-1915; Walking Liberty 1916-1947; Franklin 1948-1963; Kennedy 1964 | .900 | 12.50 g | 0.36169 troy oz |
| Kennedy half dollar | 1965-1970 only | .400 | 11.50 g | 0.14790 troy oz |
| Jefferson wartime nickel | 1942-1945 with the large P, D, or S above Monticello on the reverse | .350 | 5.00 g | 0.05626 troy oz |
| Morgan dollar | 1878-1904 and 1921 | .900 | 26.73 g | 0.77344 troy oz |
| Classic Peace dollar | 1921-1928 and 1934-1935 | .900 | 26.73 g | 0.77344 troy oz |
| Eisenhower dollar, silver-clad collector issue | 1971-1976, qualifying collector issue only | .400 | 24.59 g | 0.31610 troy oz |
| American Silver Eagle | 1986-date program | .999 fine | 31.103 g | 1.00000 troy oz |
Table specifications are for the named coin types, not every coin bearing a similar year. In particular, only the wartime nickel with the oversized reverse mint mark belongs in the 35% silver group. For dollar coins, confirm the series before using a silver figure: a classic Peace dollar has a different specification from a modern collector Peace dollar, and most modern circulating dollar coins are not silver.[2]
How fineness becomes actual silver weight
Fineness is the proportion of a coin's mass that is silver. A .900 half dollar weighs 12.50 grams at issue, so its pure silver portion is 11.25 grams. Converting that fine-silver mass to troy ounces produces the familiar 0.36169 troy-ounce figure. The same method works for any coin once its correct specifications are known.
Formula for fine silver in troy ounces:
gross weight in grams × silver fineness ÷ 31.1034768 = actual silver weight in troy ounces
Example, full-weight 90% half dollar:
12.50 g × 0.900 ÷ 31.1034768 = 0.36169 troy oz of silver
Use a troy ounce, not an ordinary avoirdupois ounce, for bullion pricing and these calculations. If a reference already states ASW, use that published troy-ounce amount instead of reconverting rounded gram weights. NGC's coin reference provides both the original coin weight and ASW for the common issues above.[2]
Calculate melt value without inventing a price
Melt value starts with the coin's silver content and a current silver spot price stated in U.S. dollars per troy ounce. It measures the theoretical metal value before a dealer's bid, retail premium, authentication work, shipping, taxes, or collector considerations. Record the data source and time because the silver price changes.
Melt-value formula:
quantity × actual silver weight per coin in troy ounces × silver spot price in USD per troy ounce = estimated melt value in USD
Current-data slot: Silver spot price: [insert USD per troy oz] | Source: [insert live source] | Observed: [insert date and time with time zone]
For example, a full-weight 90% quarter uses 0.18084 troy ounce in the formula. For a group of 10, use 1.8084 troy ounces before multiplying by the observed spot quote. For ordinary circulated 90% coin lots traded by face value, buyers and sellers often use a lower 0.715 troy-ounce estimate per $1 face value to allow for normal wear, rather than the approximately 0.7234 troy ounces at original specification weight. Use one convention consistently and state which you used.[4]

Why a coin can be worth more, or less, than melt
Melt value is useful as a metal-content benchmark, but it is not an appraisal. A genuine coin may carry collector value based on its date, mintmark, condition, originality, variety attribution, and current demand. Conversely, a dealer's purchase offer may be below gross melt value because verification, handling, resale demand, and market spread matter. NGC likewise distinguishes intrinsic metal value from numismatic value in its melt-value guide.[2]
Wear matters too. The ASW table gives the amount in a newly issued, full-weight coin. A circulated coin can have minor metal loss, damage, deposits, or scale variation. Do not use a lower scale weight alone to declare a coin counterfeit, and do not clean, file, drill, or acid-test a potentially collectible coin. Confirm design, measurements, and the exact issue with a qualified dealer or recognized grading service when authenticity or collector value could materially change the decision.
A classic silver dollar deserves its own check before it is grouped with generic bullion. See Peace Dollar Silver Content for the standard 0.77344-troy-ounce calculation and issue-specific cautions. Likewise, the Barber Half Dollar Silver guide explains the full-weight 90% half-dollar standard in more detail.
A practical silver-coin identification checklist
- Read the denomination and date. Start with the coin's stated value and year, not its color.
- Match the design to the series. A Washington quarter, a bicentennial collector issue, and a commemorative can require different references.
- Apply the date rule for that exact type. A 1964 half dollar and a 1965 Kennedy half dollar do not have the same silver content.
- Inspect the edge as a screening clue. A copper-colored core generally rules out the familiar 90% silver dime or quarter, but edge appearance is not proof of authenticity.
- Check special identifiers. For wartime nickels, look for the large P, D, or S above Monticello. For special dollars and proof issues, consult the original Mint or series reference.
- Separate metal math from collector research. Calculate ASW and melt only after identification; then check whether the coin warrants a numismatic review.
Next step: Identify the exact coin first, then use the live calculator or browse Agate's current inventory for current availability, pricing, premiums, shipping terms, and policies. Those details can change and should be confirmed on the live page before a transaction.
Frequently asked questions
How much silver is in a 1964 quarter?
A standard 1964 Washington quarter is 90% silver and has an original actual silver weight of about 0.18084 troy ounce. That figure assumes the normal circulating issue at original specification weight; wear can reduce the physical weight slightly.
Are all coins dated before 1965 silver?
No. The familiar rule applies mainly to dimes and quarters through 1964 and certain half dollars. Cents are not silver, ordinary nickels are not silver, and a coin's exact denomination and type still matter. A 1942-1945 Jefferson nickel is silver only when it is the wartime alloy identified by the large mint mark above Monticello.
How much silver is in a 1965-1970 Kennedy half dollar?
A regular Kennedy half dollar dated 1965 through 1970 contains 40% silver and about 0.14790 troy ounce of fine silver at original specification weight. It should not be calculated as a 90% 1964 Kennedy half.[2]
How much silver is in a Peace dollar?
A classic 1921-1935 Peace dollar contains about 0.77344 troy ounce of silver at its original .900 standard. Modern collector issues may use different specifications, so check the product or Mint record for the exact issue.
How do I find a silver coin's melt value today?
Find the coin's correct ASW, record a current silver spot price in USD per troy ounce with a time stamp, and multiply quantity × ASW × spot. The result is a metal-value estimate, not a guaranteed cash offer or a collector appraisal.
Conclusion
The answer to how much silver is in a U.S. coin begins with identification, not appearance. Once the denomination, date, and issue are confirmed, use the exact ASW in the table and a time-stamped spot quote for a disciplined melt estimate. Keep that metal calculation separate from a coin's possible collector value, and get qualified help before selling or altering a piece that may merit closer review.
