The silver half dollar melt value depends on which era your coin comes from -- 90% silver (pre-1965), 40% silver (1965-1970), or the special 1976-S Bicentennial silver half. Select your coin's date range and the calculator auto-applies the correct silver weight.
A 90% silver half dollar (pre-1965) contains 0.3617 troy oz of pure silver; a 40% silver half (1965-1970 or 1976-S Bicentennial) contains 0.1479 troy oz.
With silver spot at $33.25 per troy oz, a 90% silver half dollar has a melt value of $12.03 (using ASW 0.3617 oz). A 40% silver half dollar -- the 1965-1970 Kennedy clad series and the 1976-S Bicentennial special-mint half -- contains 0.1479 troy oz and melts at roughly 41% of the 90% figure. Kennedy halves dated 1971 and later contain zero silver; their melt value is effectively the base metal content only. The silver half dollar melt value changes every time the spot price moves, which is why the calculator above updates live.
Before you sell any silver half dollar at bullion prices, check the date and mint mark. Several Walking Liberty and Franklin issues trade at multiples of their silver melt value even in circulated grades -- selling them as junk silver would be a costly mistake.
| Variety | Circulated value (G-VF) | Why |
|---|---|---|
| 1921 Walking Liberty Half | $100 - $250+ | Absolute key date of the Walking Liberty series with very low mintage. |
| 1921-D Walking Liberty Half | $100 - $250+ | Co-key date of the Walking Liberty series; commands a strong premium even in low grades. |
| 1921-S Walking Liberty Half | $100 - $250+ | Lowest-mintage of the three 1921 issues and co-key to the entire Walking Liberty set. |
| 1938-D Walking Liberty Half | $50 - $80+ | Semi-key date with low mintage; trades well above silver melt in all grades. |
| 1949-S Franklin Half | $15 - $30+ | Semi-key Franklin with lower mintage than most dates in the series. |
| 1955 Franklin 'Bugs Bunny' FS-401 | $25 - $50+ | Die clash error gives Franklin a buck-toothed appearance; sought by variety collectors. |
No other US denomination has a more complex silver history than the half dollar. When Congress passed the Coinage Act of 1965, signed July 23, 1965, it eliminated silver entirely from dimes and quarters. For the half dollar, political pressure produced a compromise: silver content was reduced from 90% to 40%, not eliminated. The result was a transitional clad sandwich: outer layers of 80% silver / 20% copper bonded to an inner core of 21% silver / 79% copper, yielding a net composition of 40% silver and 60% copper. The net silver weight dropped from 0.3617 troy oz to 0.1479 troy oz per coin.
The 40% silver era (1965-1970) was intended to keep the half dollar circulating as a prestigious coin. It failed almost immediately. The silver content -- even at 40% -- was worth more than face value at prevailing silver prices, so the public hoarded every one they encountered. The coins vanished from commerce within months of release. By 1969 it was clear the 40% compromise had not solved the hoarding problem; the Treasury announced the shift to full copper-nickel clad for 1971.
The 1976 Bicentennial complicates the picture further. To mark the nation's 200th anniversary, the Mint struck special 3-coin silver Bicentennial sets containing a 40% silver proof half, a 40% silver proof quarter, and a 40% silver proof dollar. These were sold directly to collectors. At the same time, hundreds of millions of 1976 Bicentennial halves were struck in standard copper-nickel clad for general circulation. Both share the same dual-date '1776-1976' obverse and the drummer-boy reverse -- the only reliable distinguishing features are the 'S' mint mark, the solid silver edge, and the proof or special-mint finish.
Understanding which era your coin belongs to is the essential first step. The calculator above uses a date-range selector specifically to remove this burden: select your coin's date range and the correct ASW (0.3617 for 90%, 0.1479 for 40%, 0 for clad) is applied automatically.
| Era | Years | Composition | Metal content |
|---|---|---|---|
| 90% Silver Era | 1892-1964 | 90% silver, 10% copper | |
| 40% Silver Clad Era | 1965-1970 | 40% silver, 60% copper (clad sandwich) | |
| 1976-S Bicentennial Silver (special-mint only) | 1976 S-mint in silver sets only | 40% silver, 60% copper (clad) | |
| Base Metal Era | 1971-1974, 1976 circulation, 1977+ | 75% copper / 25% nickel clad on pure copper core |
The 1976 Bicentennial half dollar is the single most-asked-about coin on this site, because the same design was struck in two completely different compositions. The silver version (40% silver, ASW 0.1479 oz) was produced exclusively at the San Francisco Mint for inclusion in special 3-coin Bicentennial silver sets -- roughly 4 million silver proof sets and 11 million silver uncirculated sets were sold. The clad version was struck at Philadelphia (no mint mark), Denver (D), and San Francisco (S) for general circulation; these contain zero silver.
The confusion is real and understandable: both versions bear the dual date '1776-1976', both show the same Jack L. Ahr drummer-boy reverse design, and both are the same diameter (30.0 mm). The differences are subtle but definitive. Mint mark alone is not sufficient -- a 1976-S could be either the silver proof or the common clad proof struck at San Francisco for uncirculated sets. The edge profile and the coin's finish and provenance are the clinchers.
The half dollar is the most metallurgically complex US silver denomination. Unlike dimes and quarters, which transitioned cleanly from 90% silver to clad in 1965, the half dollar went through a transitional 40% silver era that lasted until 1970. Then the 1976 Bicentennial introduced a further wrinkle: two different compositions struck in the same year. Use the table below to identify what you have before entering it in the calculator.
| Year | Composition | Silver content |
|---|---|---|
| 1892-1915 | 90% silver, 10% copper | 0.3617 troy oz ASW (Barber Half) |
| 1916-1947 | 90% silver, 10% copper | 0.3617 troy oz ASW (Walking Liberty Half) |
| 1948-1963 | 90% silver, 10% copper | 0.3617 troy oz ASW (Franklin Half) |
| 1964 | 90% silver, 10% copper | 0.3617 troy oz ASW (Kennedy Half -- first year) |
| 1965-1970 | 40% silver, 60% copper (clad) | 0.1479 troy oz ASW (Kennedy Half clad era) |
| 1971-1974, 1977+ | Copper-nickel clad (75% Cu / 25% Ni outer; pure Cu core) | Zero silver -- no melt value |
| 1976 (P, D, or S clad) | Copper-nickel clad -- Bicentennial circulation strike | Zero silver -- no melt value |
| 1976-S (special silver sets only) | 40% silver, 60% copper (clad) | 0.1479 troy oz ASW (Bicentennial silver proof / uncirculated sets) |
Four quick tests help identify your half dollar's composition. Edge test: look at the coin's edge straight-on -- a solid, uniform silver-colored edge indicates a 90% or 40% silver coin, while a visible copper-orange stripe running through the middle marks a clad coin with no silver. Date test: any half dated 1971 through 1974 or 1977 onward is clad; any half dated 1892 through 1964 is 90% silver; any half dated 1965 through 1970 is 40% silver. Ring test: drop a silver half on a hard surface -- 90% and 40% silver halves produce a clear, sustained ring, while clad coins produce a dull thud. Weight test: a 90% silver half weighs 12.50 g; a 40% silver half weighs 11.50 g; a clad Kennedy weighs 11.34 g -- a precise postal or coin scale distinguishes them reliably.
A standard half dollar roll contains 20 coins ($10.00 face value). The silver content per roll differs sharply between the 90% and 40% eras -- use the correct row for your coins.
| Unit | Face value | Silver content |
|---|---|---|
| Single 90% silver half (Barber / Walking / Franklin / 1964 Kennedy) | $0.50 | 0.3617 troy oz silver |
| Roll of 90% silver halves (20 coins) | $10.00 | 7.234 troy oz silver (20 x 0.3617) |
| $1,000 face value bag -- 90% silver halves | $1,000.00 | ~715 troy oz silver (0.715 oz per $1 face; ~2,000 coins; ~55 lbs total) |
| Single 40% silver half (1965-1970 Kennedy or 1976-S Bicentennial) | $0.50 | 0.1479 troy oz silver |
| Roll of 40% silver halves (20 coins) | $10.00 | 2.958 troy oz silver (20 x 0.1479) |
| $1,000 face value -- 40% silver halves | $1,000.00 | ~295 troy oz silver (0.295 oz per $1 face) |
| 1971+ Kennedy half (clad) | $0.50 | Zero silver |
Melt Value = ASW × Spot Price
The melt value formula is straightforward: multiply the coin's Actual Silver Weight (ASW) in troy ounces by the silver spot price in dollars per troy oz. For a 90% silver half dollar (Barber, Walking Liberty, Franklin, or 1964 Kennedy), the ASW is 0.3617 troy oz. For a 40% silver half (1965-1970 Kennedy or 1976-S Bicentennial), the ASW is 0.1479 troy oz. At a reference spot of $33.00 per troy oz: 0.3617 x $33.00 = $11.94 per 90% half; 0.1479 x $33.00 = $4.88 per 40% half.
The 0.3617 figure comes from the coin's statutory specifications: total weight 12.50 grams, silver fraction 90%, divided by 31.1035 grams per troy ounce (12.50 x 0.90 / 31.1035 = 0.3617). For the 40% series: 11.50 g total weight x 0.40 / 31.1035 = 0.1479 troy oz. These are theoretical mint-state figures for an uncirculated coin. Circulated coins lose a small amount of silver to wear; the industry convention is to apply a junk silver multiplier instead of the per-coin ASW when valuing circulated bulk lots.
For circulated bulk lots, the junk silver multiplier simplifies the math. The convention for 90% silver coinage is 0.715 troy oz of silver per $1.00 of face value -- slightly below the theoretical 0.7234 oz/dollar to account for average wear. For 40% silver halves, the equivalent multiplier is 0.295 troy oz per $1.00 face. At $33.00 spot: $1.00 face in 90% silver halves = 0.715 x $33.00 = $23.60; $1.00 face in 40% silver halves = 0.295 x $33.00 = $9.74. A $10.00 face roll of 90% halves therefore contains approximately $236.00 in silver melt; a $10.00 face roll of 40% halves contains approximately $97.40.
For a $1,000 face value bag of 90% silver halves -- a standard wholesale unit of roughly 2,000 coins weighing about 55 lbs -- the silver content is approximately 715 troy oz at the junk multiplier, worth $23,595 at the $33.00 reference spot. Dealers buying bags typically pay 85-100% of this figure depending on market conditions, refining costs, and their own inventory position.
The calculator on this page applies the correct ASW automatically based on the date range you select. You do not need to know whether your coin is 90% or 40% silver -- the date-range selector does that work. The optional wear-coefficient toggle switches between the theoretical ASW (mint state) and the industry circulated multiplier (0.715 for 90% or 0.295 for 40%) so you can model both scenarios.
One important note: the melt value is the floor, not the ceiling, for most silver half dollars. Key-date Walking Liberty halves (1921, 1921-D, 1921-S), semi-key Franklins (1949-S), and die-variety pieces like the 1955 'Bugs Bunny' all trade above melt -- often far above. The melt calculation tells you the minimum you should accept; collector demand sets the actual ceiling.
The right venue depends on whether your coins are common dates worth bullion only, or whether any might be key-date pieces worth numismatic evaluation. For true junk silver, three channels dominate.
| Venue | Typical payout | Friction |
|---|---|---|
| Local coin shop (LCS) | 85-100% of spot melt value | Walk in, get an offer same day. No shipping risk. Dealer examines for key dates, which protects you from underselling a 1921 Walking Liberty -- but LCS margins vary widely. |
| Online bullion dealers (APMEX, JM Bullion, etc.) | 90-100% of melt, sometimes slightly above for 90% silver bags | Requires shipping your coins insured; payment in 1-3 business days after receipt. Quotes are locked at time of order but subject to spot movement during transit. |
| eBay (sold by the roll or lot) | 100-130% of melt (realized prices vary by lot size and listing quality) | Highest potential payout but requires photography, listing, packing, shipping, and absorbing ~13% in fees. Best suited for mixed date rolls with potential key dates that attract collector buyers. |
The spread between what dealers pay and what silver actually trades for reflects real economics: dealers must cover refining costs, transportation, insurance, and their own margin to remain solvent. For 90% silver halves, expect offers in the 85-100% range; for 40% silver halves, some dealers discount further because the series has less collector demand and higher refining complexity. Walking Liberty key dates (1921, 1921-D, 1921-S) may attract premiums above melt even from dealers, since they resell to collector markets. Always get two or three quotes before committing to any single offer.
The 'spread' is the gap between what you calculate as melt value and what a dealer actually pays you. For silver half dollars, dealers typically offer somewhere in the range of 85-100% of the calculated melt value for common-date 90% silver coins and 40% silver coins. That range is wide by design -- it reflects a genuine range of outcomes, not a single fixed haircut.
Several factors move a dealer's offer within that range. Refining costs matter: converting physical coins into .999 fine silver requires transportation, assay fees, and smelting, all of which eat into the silver's gross value. Inventory position matters too: a dealer holding excess junk silver inventory will shade their offer lower; a dealer who just sold a bag and needs to restock may offer at or above 100% of melt. Market volatility matters: when spot prices are rising fast, dealers widen spreads to protect against adverse moves between purchase and sale. Denomination mix matters for 40% Kennedy halves specifically, which some refiners charge more to process due to their clad structure.
The practical implication: the melt value shown by this calculator is a reference ceiling for what you might receive, not a guaranteed transaction price. Selling to multiple venues and comparing offers -- at least two, ideally three -- closes most of the gap between the calculator figure and your actual proceeds. eBay realized prices for 90% silver half dollar rolls frequently land above calculated melt, especially for lots marketed to collector buyers who may pay premiums for date sets or mint sets within the roll.
Every half dollar struck from 1892 through 1964 is 90% silver (Barber, Walking Liberty, Franklin, and the first-year Kennedy). Half dollars dated 1965 through 1970 are 40% silver clad. The 1976-S Bicentennial half is 40% silver, but only the version sold in special silver sets -- the hundreds of millions of 1976 circulation halves are copper-nickel clad with zero silver. Any Kennedy half dated 1971 through 1974 or 1977 onward contains no silver at all.
A 90% silver half (pre-1965) contains 0.3617 troy oz of pure silver and weighs 12.50 grams. A 40% silver half (1965-1970 Kennedy or 1976-S Bicentennial) contains 0.1479 troy oz of pure silver and weighs 11.50 grams. The 40% coin is a clad sandwich -- outer layers of 80% silver / 20% copper bonded to a core of 21% silver / 79% copper -- rather than a solid alloy. At the same spot price, a 40% silver half is worth roughly 41% of what a 90% silver half is worth in melt terms.
It depends entirely on the year. The 1964 Kennedy half is 90% silver with an ASW of 0.3617 troy oz. Kennedy halves from 1965 through 1970 are 40% silver with an ASW of 0.1479 troy oz. Kennedy halves from 1971 onward (except the 1976-S silver Bicentennial special-mint versions) contain no silver. Checking the date -- and the edge profile -- is the fastest way to determine whether your Kennedy half has any silver content.
It depends on which version you have. The 1976-S Bicentennial half sold in special 3-coin silver sets contains 0.1479 troy oz of silver (40% composition). All other 1976 Bicentennial halves -- Philadelphia (no mint mark), Denver (D), and the standard S-mint -- are copper-nickel clad with zero silver. Look at the edge: a solid uniform silver edge means the 40% silver version; a visible copper stripe through the edge means clad.
No. The 1971 Kennedy half was the first year of full copper-nickel clad production after the 40% silver era ended. A 1971 half dollar contains no silver and has no bullion melt value beyond the base metal. The same is true for all Kennedy halves from 1971 through 1974 and from 1977 onward -- these are all clad coins.
A Walking Liberty half (1916-1947) contains 0.3617 troy oz of pure silver -- the same ASW as any other 90% silver half dollar. At a spot price of $33.25, the melt value is $12.03 per coin. For circulated bulk lots, the industry convention is 0.715 troy oz per $1.00 of face value. Keep in mind that the 1921, 1921-D, and 1921-S Walking Liberty halves are key dates worth significantly more than melt even in circulated grades.
Two tests work immediately. First, check the date: 1964 = 90% silver; 1965-1970 = 40% silver; 1971+ = no silver (except 1976-S special sets). Second, look at the edge: a solid silver-colored edge indicates a silver coin (90% or 40%); a copper-orange stripe running through the edge indicates a clad coin with zero silver content. A digital postal scale can add confirmation -- 90% halves weigh 12.50 g, 40% halves weigh 11.50 g, and clad Kennedys weigh 11.34 g.
The 1921, 1921-D, and 1921-S Walking Liberty halves are the three co-keys of the series. All three date from the revival year after a production gap and had low mintage figures. Circulated examples trade in the $100-$250+ range depending on grade -- far above their silver melt value of under $12 at recent spot prices. The 1938-D is a semi-key with a collector premium in the $50-$80+ range. Any of these dates should be evaluated by a dealer or submitted for grading before being sold as bullion.
A standard roll contains 20 halves ($10.00 face value). For 90% silver halves, the melt value is approximately 0.715 troy oz x spot price x $10 face = roughly $235-$240 at $33.00 spot. For 40% silver halves, the roll melt value is approximately 0.295 x spot x $10 face = roughly $97-$98 at $33.00 spot. The actual amount you receive from a dealer will be 85-100% of the calculated melt, depending on the buyer and market conditions.
No. Cleaning a silver coin -- even with a gentle polish -- removes the natural toning (patina) that collectors and dealers recognize as original surface. A cleaned coin is immediately identifiable and will be graded 'details' by professional grading services, sharply reducing its numismatic value. For common-date coins sold strictly as bullion, cleaning does not affect the melt calculation, but it eliminates any upside if the coin turns out to be a better date. Leave coins in the condition you found them.
For 90% silver half dollars, the standard junk silver multiplier is 0.715 troy oz per $1.00 of face value. This figure is slightly below the theoretical 0.7234 oz per dollar to account for average wear on circulated coins. For 40% silver half dollars (1965-1970 Kennedy and 1976-S Bicentennial), the multiplier is 0.295 troy oz per $1.00 of face value. Multiply either figure by the current spot price to get the per-dollar-face melt value for a bulk lot.
Most Franklin halves (1948-1963) trade at or very near their silver melt value of 0.3617 oz x spot price, because the series had large mintage figures for most dates. The 1949-S is a semi-key that trades at $15-$30+ above melt in circulated grades. The 1955 'Bugs Bunny' FS-401 die variety commands $25-$50+ from variety collectors. Otherwise, the Franklin series is a reliable and common source of 90% silver bullion.
The melt value is only part of the picture. Walking Liberty key dates, Franklin varieties, and silver Bicentennial halves all have numismatic layers worth understanding before you transact.
