1940 Half Dollar Value (2026 Guide): Errors List, “S” & No Mint Mark Worth

In most coin series, flaws destroy value — but the 1940-S Walking Liberty Half Dollar breaks every rule. This coin holds the notorious distinction of being the worst-struck coin in the entire Walking Liberty series, with Liberty’s left hand often completely invisible on most specimens.

Yet that very defect has made it the rarest Walking Liberty variety of the entire 1940s decade. While typical circulated 1940 halves start near their silver melt value, a sharply struck 1940-S in MS67 sold for $35,250 at Heritage Auctions in April 2013 — a stunning price for a coin most people would overlook.

What separates smart collectors from casual searchers is knowing exactly what drives these values. This guide covers every variety, every key auction record, and every grading detail you need.

Top 10 Most Valuable 1940 Half Dollar Worth Money

The 1940 Walking Liberty half dollar market reveals striking value contrasts across different mint marks and grades.

The 1940-S MS67 specimen reached $35,250 at Heritage Auctions in April 2013. This result reflects how extreme the scarcity of well-struck San Francisco examples truly is — even more so than many collectors realize.

The regular Philadelphia 1940 MS68+ achieved $29,375 at Legend Rare Coin Auctions in September 2019. Pristine condition transforms an ordinary strike into a premium collectible commanding serious money.

The 1940 Proof PR68 has sold for $19,200 at Heritage Auctions in June 2021. These specially made pieces attract dedicated collectors willing to pay strong premiums. Stack’s Bowers also sold a 1940 Proof example in their June 2012 Baltimore Auction for $3,760, illustrating the wide range that exists depending on grade and eye appeal.

 

History of The 1940 Half Dollar

The Walking Liberty Half Dollar was designed by sculptor Adolph A. Weinman, who won a design competition held by the Commission of Fine Arts in 1916. Weinman was so talented that he received commissions for both the half dollar and the dime — an unprecedented achievement for a single artist at the time.

Art historian Cornelius Vermeule later called the Walking Liberty “one of the greatest coins of the United States — if not of the world.” The design’s popularity has endured: since 1986, a modified version of Weinman’s obverse has appeared on the American Silver Eagle bullion coin.

The 1940 Walking Liberty emerged during a pivotal period in American economic history. The nation was rapidly shifting from Depression-era recovery to wartime preparation. President Roosevelt and Congress approved the nation’s first peacetime military draft in September 1940, fundamentally altering American society while these silver coins were still rolling off mint presses.

Only the Philadelphia and San Francisco mints produced Walking Liberty halves that year. The Denver Mint focused on lower denominations. The silver composition remained unchanged at 90% purity, reflecting a monetary system not yet constrained by wartime metal shortages. Within two years, strategic material pressures would force dramatic changes to American coinage — making 1940 one of the final years when precious metals flowed freely into everyday currency.

Proofs were struck from 1936 through 1942, and the 1940 issue marks the fifth consecutive year of Walking Liberty proof production. Collectors have carefully preserved the majority of these proof strikes, which is reflected in the exceptional 86% survival rate seen in mintage data.

Key Features of The 1940 Half Dollar

The 1940 half dollars can be found with well-preserved sharpness, bright white luster, or soft golden iridescence. Strike quality varies significantly by mint location, especially for the San Francisco issue, creating notable differences in detail and overall appearance.

The Obverse Of The 1940 Half Dollar

The obverse features Liberty walking toward the rising sun, draped in the American flag. Her right hand points forward and her left hand holds branches of laurel and oak — symbols of civil and military glory, as described in Treasury Secretary McAdoo’s 1916 annual report.

The inscription “LIBERTY” curves along the upper rim. The national motto “IN GOD WE TRUST” appears in the right field, and the date “1940” sits at the bottom edge.

The Reverse Of The 1940 Half Dollar

The reverse shows a majestic bald eagle perched on a mountain crag, with its wings unfolded. “UNITED STATES OF AMERICA” runs near the top edge, “HALF DOLLAR” along the bottom rim, and “E PLURIBUS UNUM” directly below the eagle’s beak.

The mint mark, when present, appears on the reverse near the eagle’s perch — at roughly the 7 o’clock position on San Francisco specimens. This placement has been consistent since the mint mark was moved from the obverse partway through 1917.

Other Features Of The 1940 Half Dollar

Each coin maintains standard specifications: 30.6 millimeters in diameter, 12.50 grams in weight, and a composition of 90% silver and 10% copper. The actual silver weight is 0.36169 troy ounces per coin. At current silver prices (around $48+ per troy ounce as of early 2026), the melt value of a 1940 half dollar has climbed significantly above its face value of 50 cents.

The reeded edge contains 150 vertical lines, providing both security and aesthetic appeal. There are no known 1940 Denver Mint (D) half dollars — if you encounter one, it is a counterfeit.

1940 Half Dollar Mintage & Survival Data

Philadelphia’s 9,156,000 coins dominated the 1940 Walking Liberty half dollar mintage. San Francisco produced 4,550,000 pieces — significantly fewer, and with far worse strike quality. For proof issues, production remained limited to just 11,279 specially struck coins from Philadelphia.

Survival analysis reveals intriguing preservation trends. Philadelphia coins show approximately 450,000 surviving examples with a 4.91% survival rate. San Francisco specimens show a remarkably similar 4.95% survival rate. Most striking is the proof coins’ exceptional 86.4% survival rate — nearly 9,750 examples preserved — a testament to how carefully collectors have stewarded these premium strikes over the past 85 years.

1940 Half Dollar Grading

To judge a 1940 Walking Liberty half dollar’s value, start by examining Liberty’s left hand and her breast — flattening or missing detail signals circulation or a weak strike. Check the eagle’s breast and left leg on the reverse; merged feathers indicate wear.

Compare Liberty’s full figure and skirt lines for sharpness. On the 1940-S, weak striking is normal, so look for any surviving hand detail as a premium indicator. Note any contact marks. PCGS and NGC are the two most respected third-party grading services (Professional Coin Grading Service and Numismatic Guaranty Corporation) — their certified grades carry the most weight in the market.

Coins with well-preserved details and minimal blemishes generally command higher value. For a fast, reliable way to check condition and potential worth, the CoinValueChecker App instantly highlights key features and estimates market value.

 

1940 Half Dollar Value Guides

Collectors can identify three distinct categories within the 1940 Walking Liberty half dollar series. Each represents a different mint facility and striking process.

1940 Half Dollar Categories:

• 1940 No Mint Mark: Philadelphia mint issue with superior strike quality
• 1940-S: San Francisco mint mark with characteristic weak strikes
• 1940 Proof: Special mirror-finish specimens exclusively from Philadelphia

 

1940 No Mint Mark Half Dollar Value

The 1940 no mint mark half dollar is the technically rarest Philadelphia issue of the entire 1940s decade. Despite a mintage of 9,156,000 coins, finding examples with original mint luster and sharp strike details has become increasingly challenging.

PCGS CoinFacts notes that this issue is “usually very sharply struck” with “many Superb Gems known with either pure white luster or beautiful iridescent light gold toning.” PCGS co-founder David Hall has specifically noted that while this coin is rare among 1940s Philadelphia issues, it is still findable even in Gem condition — making it a strong value for condition-focused collectors.

The auction record stands at $29,375 for an MS68+ example sold by Legend Rare Coin Auctions on September 26, 2019. That result illustrates how a single grade point at the top of the scale can translate into thousands of dollars of premium.

High-grade examples have shattered expectations at major auction houses, with pristine specimens commanding premium prices that reflect their true scarcity.

Recent market patterns reveal an accelerating collector interest that has fundamentally shifted this coin’s market dynamics.

 

1940-S Half Dollar Value

The 1940-S half dollar carries the notorious distinction of being the worst-struck coin in the entire Walking Liberty Half Dollar series. The typical 1940-S is so weakly struck at Liberty’s left hand that many specimens show no hand detail whatsoever.

With a mintage of just 4,550,000 pieces — significantly lower than its Philadelphia counterpart — this San Francisco issue earns the collector phrase “flat as a pancake.” The PCGS CoinFacts page for this coin states this description directly.

What makes this coin fascinating to collectors is that it is actually rarer than the more famous 1941-S in both uncirculated and Gem condition. The 1941-S gets more attention because of a historical quirk: coin albums from earlier decades split the Walking Liberty series into two books, with 1941-1947 as the popular “short set.” The 1941-S is the rarest coin in that short set, earning it ongoing fame. However, numismatic experts confirm the 1940-S is definitively rarer overall.

The top auction result for this variety is $35,250 at Heritage Auctions in April 2013, for an MS67 example — the highest price in the market for this date. Stack’s Bowers also sold a 1940-S example in November 2021 for $8,400, showing strong demand continues. The scarcity of well-struck pieces has created a genuine numismatic treasure hunt among advanced collectors.

According to auction records, premium examples with sharp hand details have commanded extraordinary prices, defying expectations for this “problematic” issue.

Collector fascination with this striking anomaly has created a robust and growing market demand.

 

1940 Proof Half Dollar Value

With a mintage of 11,279 pieces, the 1940 proof half dollar stands as the “phantom cameo” of the series. No specimens have ever been certified with Cameo (CAM) or Deep Cameo (DCAM) designations by either PCGS or NGC — making this the only year in the Walking Liberty proof run with zero cameo-designated examples.

CAM means a coin has frosted design devices that contrast against mirror-polished background fields. DCAM (Deep Cameo) is the highest designation, with the strongest possible contrast. Their complete absence on all 1940 proofs is unusual and diagnostic. Any 1940 proof offered with a cameo or deep cameo designation should be viewed with extreme suspicion.

The 1940 proof is described by PCGS CoinFacts as “slightly scarcer than the 1941 and 1942” issues. Stack’s Bowers notes that from the 11,279 proof mintage, the coin “is widely available up to and including PR-68,” but PR-68+ examples are genuinely rare. Stack’s sold a 1940 proof in their June 2012 Baltimore Auction for $3,760. The top result is $19,200 for a PR68+ sold by Heritage Auctions in June 2021.

The market dynamics here are intriguing for alert collectors. While readily available through PR67, the “no cameo” characteristic positions PR68+ examples as potential sleepers in a market increasingly focused on cameo premiums.

Here is the complete auction data to help you understand its value more clearly.

Growing specialist recognition of this proof’s distinctive technical attributes has begun reshaping collector preferences in the advanced proof market.

Rare 1940 Half Dollar Error List

As with all Walking Liberty half dollars, the 1940 issues are prone to various error types. This is partly due to the complex high-relief design created by Adolph Weinman, which presented significant striking challenges throughout the entire series. Because the coin’s highest design points on the obverse (Liberty’s head, torso, and left leg) are directly opposite the eagle’s breast on the reverse, the dies had to work especially hard — making errors more likely.

The following error types are the most commonly encountered varieties. They can dramatically increase the value of these already collectible coins.

1. Doubled Die Errors (DDO and DDR)

A Doubled Die Obverse (DDO) occurs when the working die receives multiple impressions from the master hub during die-making, with each impression slightly misaligned. This creates visible doubling of design elements that is raised on the coin’s surface — not a trick of the light.

On the 1940 obverse, doubling may appear in Liberty’s figure, the word “LIBERTY,” or the date “1940.” A Doubled Die Reverse (DDR) shows doubling in the eagle’s features or the lettering like “UNITED STATES OF AMERICA” or “HALF DOLLAR.”

These errors are relatively easy to spot with magnification. Unlike post-mint damage, genuine doubled dies show equal sharpness in both the original and doubled element.

2. Double Strikes and Planchet Errors

A double strike occurs when a coin is struck twice by the dies, often with the second strike slightly offset. This creates overlapping design impressions on the same coin.

Planchet errors include coins struck on wrong-size or wrong-composition blanks. A notable example in the broader Walking Liberty series is a 1942 Walking Liberty struck on a quarter-dollar planchet — one of perhaps only five known examples, as reported by Coin World. For dramatic double-strike examples, values can reach $3,000–$5,000.

3. Die Cracks and Lamination Errors

Die cracks appear as raised lines on the coin surface, formed when aging dies develop fractures during the striking process. Small cracks add modest premiums; large, dramatic breaks across the coin face attract strong collector interest.

Lamination errors occur when impurities or defects in the metal cause parts of the coin’s surface to peel, split, or flake. These surface anomalies are distinctive and appeal to error coin specialists. It is important to distinguish genuine lamination errors from post-mint damage — genuine laminations typically show sharp, consistent edges where the metal has peeled away.

4. Repunched Mintmark Errors (RPM)

RPM (Repunched Mintmark) errors result from the mintmark punch being applied more than once at slightly different positions during working die preparation. Before 1989, mintmarks were applied by hand — this manual process meant occasional double or shifted impressions.

The 1940-S issues can exhibit these errors, where the “S” shows evidence of being punched more than once. Look for a doubled or shadowed “S” on the reverse near the eagle’s perch. Magnification of 5x to 10x is usually sufficient to see the offset impressions clearly.

5. Struck-Through Errors

A struck-through error occurs when a foreign object — grease, cloth fiber, or a metal chip — lands on the coin blank before striking. The die then imprints the coin around the object, leaving a distinctive smooth void or depression in the design.

On Walking Liberty halves, struck-through grease errors are the most common type. They often appear as areas of missing or flattened detail that look superficially similar to a weak strike — but are actually caused by debris filling the die. A coin expert or grading service can distinguish between the two.

FAQ About The 1940 Half Dollar

1. What is the 1940 Half Dollar worth in circulated condition?

In average circulated (well-worn) condition, a 1940 Philadelphia half dollar is worth around its silver melt value — currently approximately $17–$30 depending on the silver spot price. A coin in Very Good (VG-8) condition fetches around $18–$23, while an Extremely Fine (XF-40) example in nicer shape can bring $25–$35.

The 1940-S in circulated grades is similar — around $18–$23 in Very Good condition and $25–$40 in Extremely Fine. The silver content of 0.36169 troy oz provides a strong price floor regardless of collector grade.

2. What makes the 1940-S half dollar different from the regular 1940 version?

The 1940-S is widely considered the worst-struck coin in the entire Walking Liberty Half Dollar series. On most specimens, Liberty’s left hand is faint or completely invisible — a flaw so consistent that PCGS CoinFacts uses the phrase “flat as a pancake” to describe it.

Despite having more than 4.5 million pieces minted, the 1940-S is actually rarer than the more famous 1941-S in both uncirculated and Gem condition. This makes finding a sharply struck specimen a genuine challenge — and commands a serious premium. A well-struck MS67 example sold for $35,250 at Heritage Auctions in 2013, compared to typical MS63 pieces worth a few hundred dollars.

3. How much silver is in a 1940 half dollar?

The 1940 Walking Liberty Half Dollar contains 90% silver and 10% copper, with an actual silver weight of 0.36169 troy ounces (approximately 11.25 grams of pure silver). At current silver prices near $48 per troy ounce in early 2026, the melt value is roughly $17–$18 per coin.

This silver content provides a permanent baseline value. Even a heavily worn 1940 half dollar is worth more than its 50-cent face value simply due to the precious metal it contains.

4. Are there any known error varieties for the 1940 half dollar?

Yes. The most common error types on 1940 Walking Liberty halves include Doubled Die Obverse (DDO) and Doubled Die Reverse (DDR) errors, where design elements appear doubled due to multiple die impressions. Lamination errors — where the coin’s surface peels or flakes due to metal impurities — also occur.

The 1940-S is additionally prone to Repunched Mintmark (RPM) errors, where the “S” mintmark was stamped more than once at a slightly different angle. Struck-through grease errors appear on both mint locations. Error coins can significantly increase value above standard market prices.

5. Why does the 1940 proof half dollar have no Cameo designation?

This is one of the most intriguing facts about this coin. No 1940 Walking Liberty proof has ever been certified with a CAM (Cameo) or DCAM (Deep Cameo) designation by either PCGS or NGC — the two leading grading services.

Cameo contrast refers to the frosted, white appearance of raised design devices against mirror-polished background fields. The 1940 proof dies apparently did not develop the level of surface relief needed to create this effect. This makes the absence of cameo a diagnostic feature of the 1940 proof — any specimen claiming a cameo designation should be treated with extreme caution.

6. Is the 1940 half dollar rare in MS68 or above?

Yes, very much so. Across the entire Walking Liberty series, only around 135 coins have been certified at MS68 by both PCGS and NGC combined (approximately 55 at PCGS and 80 at NGC, per Greysheet research). The 1940 Philadelphia MS68+ that sold for $29,375 in 2019 represents the pinnacle of what this date can achieve.

For the 1940-S, MS68 examples are essentially unknown. The combination of low mintage and poor native strike quality makes any 1940-S above MS67 extraordinarily rare.

7. How do I tell if my 1940 half dollar has been cleaned?

Look for fine hairline scratches in the coin’s fields (the flat background areas) under a good light source at a low angle. Cleaned coins also often show an unnatural, brilliant white appearance lacking the warm glow of original mint luster.

A genuinely original coin will have either bright white luster with a flow-like appearance under rotation, or natural golden or iridescent toning that forms gradually over decades. Cleaned coins are worth significantly less than uncleaned examples in the same condition, as cleaning is considered damage in the numismatic world.

8. What is the difference between MS63 and MS65 for the 1940 half dollar in terms of value?

The price difference between these grades is significant. A 1940 Philadelphia half dollar in MS63 typically sells for around $55–$80. The same coin in MS65 (also called Gem Uncirculated) can bring $90–$150 or more.

For the 1940-S, the difference is even more dramatic due to scarcity. An MS63 example might fetch $60–$100, while a well-struck MS65 can command $300–$500 or higher depending on strike quality. A single grade point at the top of the scale — say, MS67 vs. MS68 — can mean a difference of thousands of dollars for this series.

9. What were the Selective Training and Service Act of 1940 and why does it matter for this coin?

The Selective Training and Service Act, signed into law on September 16, 1940, created America’s first peacetime military draft. These 1940 Walking Liberty half dollars were literally rolling off the press as this historic legislation reshaped American life.

Within two years, wartime material demands changed American coinage significantly — including reductions in silver usage and modifications to other coin compositions. The 1940 half dollar thus captures a unique historical moment: American normalcy on the edge of total transformation.

10. Should I get my 1940 half dollar certified by PCGS or NGC before selling?

For circulated coins in VG or Fine grades, certification costs may exceed the benefit — these coins are often worth $20–$40, while grading fees typically start around $20–$40 per coin depending on service level. Silver melt value provides a reliable floor.

For uncirculated examples in MS63 or above, certification by PCGS or NGC is strongly recommended. A certified MS65 1940-S can sell for three to five times more than an uncertified example. For MS67 and above, certification is essentially mandatory — buyers at that price level require verified grades, and auctions at Heritage and Stack’s Bowers require slabbed coins to achieve record prices.
