1940 Walking Liberty Half Dollar Value Guide

The 1940 Walking Liberty Half Dollar features Adolph Weinman's iconic design

The 1940 Walking Liberty Half Dollar represents a classic issue from one of America's most beloved coin designs. Struck in 90% silver at both the Philadelphia and San Francisco mints, these coins were produced for circulation alongside special proof strikes for collectors. With values ranging from just above melt value for worn examples to over $35,000 for exceptional specimens, understanding what drives value is essential.

The 1940-S San Francisco issue presents a unique challenge for collectors: while common in lower grades, it is notorious for weak strikes that make fully detailed examples extraordinarily rare and valuable. Philadelphia issues are more readily available in high grades but still command premiums for top-quality specimens. This guide provides comprehensive pricing data, grading diagnostics, and authentication guidance to help collectors navigate this classic series.

All 1940 Walking Liberty Half Dollars share Adolph A. Weinman's celebrated design featuring Liberty striding toward the dawn. Proper identification begins with understanding the design elements and mint mark placement.

Design Features

Obverse (Front): The obverse displays a full-length figure of Liberty draped in the American flag, walking confidently toward the left. Her right arm is extended outward, while her left arm carries branches of oak and laurel symbolizing strength and peace. A rising sun appears behind her, with rays extending upward. Inscriptions include "LIBERTY," "IN GOD WE TRUST" (above Liberty's head), and the date "1940" at the bottom center.

Reverse (Back): The reverse features a majestic eagle perched on a rocky mountain crag, wings partially spread. A small pine sapling grows from the rock beneath the eagle, symbolizing America's strength and growth. Inscriptions include "UNITED STATES OF AMERICA" (upper arc), "E PLURIBUS UNUM" (beneath the eagle), and "HALF DOLLAR" (lower arc).

Mint Mark Location and Identification

The 'S' mint mark appears in the lower-left field of the reverse, below the pine sapling

The mint mark location for Walking Liberty Half Dollars was moved from the obverse to the reverse in mid-1917. For 1940 issues, the mint mark appears on the reverse, located in the lower-left field, below the pine sapling and to the left of the eagle's perch.

• 1940 (no mint mark): Struck at Philadelphia with a mintage of 9,156,000 business strikes
• 1940-S: Struck at San Francisco with an "S" mint mark; mintage of 4,550,000 business strikes
• 1940 Proof: Struck at Philadelphia for collectors; mintage of 11,279

Distinguishing Business Strikes from Proofs

The 1940 Proofs are characterized as "Brilliant Proofs" with highly mirrored fields and squared rims. Unlike business strikes, which have a softer, satiny luster from tumbling in mint bags, proofs display mirror-like surfaces and sharper, more defined details. Proof coins were sold directly to collectors in special packaging and never intended for circulation.

Current market values for 1940 Walking Liberty Half Dollars vary significantly based on mint mark, strike quality, and condition. All prices reflect recent market data from major grading services and auction results.

1940 (Philadelphia) Business Strike Values

The Philadelphia issue is the most common 1940 Walking Liberty Half Dollar, with over 9.1 million struck. PCGS estimates approximately 450,000 examples survive, with 30,000 in grades MS-65 or better. While readily available in all circulated grades, gem uncirculated specimens command significant premiums.

• MS-68+: Single finest-known example sold for $29,375(Legend Auctions, Sept 2019)

1940-S (San Francisco) Business Strike Values

The 1940-S presents one of the most complex valuation scenarios in the Walking Liberty series. With a mintage of 4.55 million, it is scarcer than the Philadelphia issue but still common in circulated grades. However, its notorious strike weakness creates two distinct markets: typical weakly-struck examples and rare fully-struck specimens.

Strike quality dramatically affects value: typical weak strike versus rare full strike

Nearly all 1940-S examples show incomplete strikes with flat details on Liberty's torso and left leg, and the eagle's breast and left leg. This strike issue is so pervasive that a 1940-S in gem condition with a full strike is considered one of the rarest entries in the entire Walking Liberty series.

Notable Auction Records for Fully Struck Examples:

• MS-67 (fully struck): $35,250(Heritage Auctions, 2013)
• MS-67 (fully struck): $13,200(Stack's Bowers, August 2020)

1940 (Philadelphia) Proof Strike Values

The Philadelphia Mint produced 11,279 proof half dollars in 1940 specifically for collectors. These are classified as "Brilliant Proofs" with highly mirrored fields but typically lacking the frosted device contrast (Cameo) seen in modern proofs.

• PF-68 (PCGS): $4,560(NGC CoinFacts, 2023)

Accurately grading Walking Liberty Half Dollars requires understanding both surface preservation and strike quality. This series is notoriously difficult to grade due to chronic strike weakness caused by poor metal flow into the dies—a problem the U.S. Mint never fully resolved.

Critical diagnostic areas: Liberty's left hand and the eagle's breast show wear and strike weakness first

Key Diagnostic Areas

Three areas are critical for evaluating both wear and strike quality:

1. Liberty's Left Hand and Branch Stem: This is the highest point on the obverse and the first area to show wear. It is also the most commonly weak area on the strike. In a well-struck coin, individual fingers should be visible with separation between them. In weakly struck coins, the hand appears as a blob even in mint state condition.
2. Eagle's Breast and Left Leg: On the reverse, the eagle's breast feathers and left leg details are critical. A strong strike shows individual feather lines across the breast. Weak strikes show flatness and lack of definition even on uncirculated coins.
3. Liberty's Head and Date: These areas show strike quality variations, particularly on branch mint issues. The date should be sharp and complete. Liberty's facial features and hair detail indicate overall strike quality.

Strike Quality vs. Wear: A Critical Distinction

Strike weakness (mint-caused flatness) can mimic wear but shows different characteristics

Many Walking Liberty Half Dollars appear worn even when they are in pristine uncirculated condition. This is due to strike weakness, not actual circulation. Learning to distinguish between the two is essential:

Strike Weakness: Flatness is even and the coin retains full mint luster across affected areas. The "missing" details were never struck up properly at the mint. Strike weakness affects specific predictable areas (Liberty's hand, eagle's breast) while other areas remain sharp.

Actual Wear: High points show smooth, polished surfaces from handling and circulation. Luster is reduced or absent in worn areas. Wear follows friction patterns and appears on the very highest points first, then gradually extends to lower relief areas.

Circulated Grades

Good-4 (G-4): Major design elements are visible but worn flat. Liberty's figure is outlined but shows no internal detail. The date and lettering are readable but may be weak in spots. Eagle is outlined with no feather detail remaining.

Very Fine-20 (VF-20): Moderate wear throughout but all major features are clear. Liberty's gown shows folds and about half the original detail lines remain. Her left hand shows some definition. The eagle's breast shows some feather separation.

Extremely Fine-40 (EF-40): Light wear on the highest points. Liberty's gown retains most detail lines. Her left hand shows partial finger separation. The eagle's breast feathers are mostly distinct with light wear on the highest areas. Full original luster may remain in protected areas.

About Uncirculated-50 (AU-50): Only slight wear visible on the absolute highest points. Liberty's hand shows minimal friction. The eagle's breast may show a trace of friction. Significant original mint luster remains (50% or more visible).

Gem grade differences: surface quality and luster intensity increase with grade

Mint State (Uncirculated) Grades

MS-60 to MS-62: No wear, but numerous bagmarks and contact marks visible. Luster may be somewhat impaired. Strike may be weak. Eye appeal is limited due to surface marks.

MS-63 (Select Uncirculated): No wear. Moderate contact marks but none distracting in prime focal areas. Good luster. May have weak strike, particularly on 1940-S examples. Overall eye appeal is acceptable.

MS-65 (Gem Uncirculated): No wear. Very few contact marks, and those present are small and not in prime focal areas. Strong, attractive luster. Better strike quality expected. Excellent overall eye appeal. For 1940-S, most examples at this grade still show strike weakness.

MS-67 (Superb Gem): No wear. Virtually mark-free surfaces with only the most minute imperfections visible under magnification. Exceptional luster. Premium strike quality. Outstanding eye appeal. For 1940-S, a coin at this grade with a full strike is an extraordinary rarity worth exponentially more than a typical weakly-struck MS-67.

Proof Grades

PF-60 to PF-63: Mirror fields with some hairlines or contact marks. Design details are sharp. Some impairments visible but overall proof character is evident.

PF-65 (Gem Proof): Deeply mirrored fields with minimal hairlines, visible only under magnification. Sharp design details. Strong eye appeal.

PF-67 to PF-68: Nearly perfect mirror surfaces with virtually no impairments. Exceptional eye appeal. Only minute hairlines visible under strong magnification. These represent the finest proof examples available.

Authentication red flags: hairline scratches from cleaning and unnatural luster

The Walking Liberty Half Dollar series has become a target for counterfeiters, and cleaning or damage to genuine coins can severely impact value. Understanding how to identify problem coins and counterfeits is essential for collectors.

Identifying Cleaned Coins: Cleaned coins show microscopic, parallel scratches called "hairlines" across the surface, especially in the open fields. These result from improper cleaning with abrasive materials or chemicals. Cleaned coins often display an unnaturally bright, sterile appearance with what collectors call "dead" or "lifeless" luster. The natural flow and texture of original mint luster is destroyed. Whizzed coins (polished with high-speed tools) show a grainy, artificial luster pattern. Cleaning is considered damage, and cleaned coins will not receive numeric grades from PCGS or NGC. Even if cleaned coins are technically uncirculated, their value typically falls to or below that of lower-grade, problem-free circulated examples.

Detecting Other Damage: Avoid coins with obvious rim dings, deep scratches, gouges, or post-mint modifications. Environmental damage such as heavy spotting, corrosion, or verdigris (green copper salts) also significantly reduces value. Bent or holed coins are considered damaged regardless of their original grade. Problem coins may be encapsulated by grading services in "details" holders with the specific issue noted ("Cleaned," "Environmental Damage," etc.) but without a numeric grade.

Counterfeit Detection: Modern deceptive counterfeits of Walking Liberty Half Dollars exist and can be sophisticated. NGC's Counterfeit Detection experts have identified key diagnostics for fake 1940 issues. Counterfeits are typically underweight by approximately 1 gram (genuine coins weigh 12.50 grams). Instead of 90% silver composition, fakes are usually a copper/zinc/nickel alloy with only about 1% silver content. The surfaces on counterfeits exhibit an odd, unnatural luster and strange die polish not seen on genuine issues. Counterintuitively, some fakes appear sharper in certain areas, such as having more pronounced sun rays than genuine coins—this results from modern laser engraving of fake dies.

Look for fine horizontal lines across Liberty's body or diagonal lines on the surfaces—these are remnants of the laser engraving process used to create counterfeit dies. The "S" mint mark shape on fakes is often incorrect compared to genuine mint marks. The designer's initials "AW" (Adolph Weinman) located on the reverse under the eagle's left wingtip may be nearly completely missing or improperly rendered on counterfeits. When in doubt about a coin's authenticity, especially for valuable high-grade examples, submission to PCGS or NGC for authentication is strongly recommended.

Proper storage and handling are essential to maintain the value of your Walking Liberty Half Dollar. Silver coins are particularly susceptible to environmental damage that can develop slowly over time, making preventive care critical.

Storage Recommendations: All 1940 Walking Liberty Half Dollars should be stored in high-quality, inert holders made from materials that do not contain polyvinyl chloride (PVC). PVC-containing flips and holders can cause green slime and corrosion that permanently damages silver coins. Acceptable storage options include non-PVC flips, archival-quality cardboard 2x2 holders with Mylar windows, or rigid plastic capsules. For any mint state or proof examples, third-party certification and encapsulation by PCGS or NGC provides the highest level of protection and is the industry standard for valuable coins.

Store coins in a stable environment with moderate temperature and low humidity. Avoid areas with temperature fluctuations or high moisture. A safe deposit box or quality home safe in a climate-controlled room is ideal. Keep coins away from rubber bands, paper clips, and other items that can cause chemical reactions. Never store coins in paper envelopes or direct contact with cardboard, as these materials contain sulfur compounds that accelerate toning.

Handling Best Practices: Always handle coins by their edges, never touching the obverse or reverse surfaces. Even clean hands contain oils and acids that can leave fingerprints and cause long-term damage. Hold coins over a soft surface to prevent damage from drops. Use cotton gloves if available, though clean hands held by the edges are acceptable for brief examination. Never attempt to clean a coin—this always reduces value, often dramatically. If a coin appears to need cleaning, consult a professional conservator or submit it to a grading service for evaluation. Natural toning developed over decades is often desirable and valuable; removing it through cleaning destroys originality and numismatic value.

While the 1940 Walking Liberty Half Dollar does not have major cataloged die varieties, several types of genuine mint errors are known to exist. These production errors occurred at the mint and can add collectible value depending on their type and visual impact.

Lamination Flaws

Lamination errors occur when impurities or gas bubbles in the silver planchet cause the metal to separate in layers. These appear as areas where the coin's surface is flaking, peeling, or missing entirely. The metal literally delaminates, showing the layered structure of the planchet. Lamination flaws can range from small surface cracks to large missing sections of metal. Examples with dramatic, visually striking laminations are more desirable to error collectors. Typical lamination flaw examples have an estimated value around $45, though this varies based on the size and location of the defect.

Die Cracks

Die cracks appear as fine, raised lines on the coin's surface, resulting from a crack that developed in the striking die. As the die continued to be used, metal from the planchet would flow into the crack, creating a raised line on the finished coin. Die cracks can be minor (short, thin lines) or major (long cracks extending across significant portions of the design, or large "cuds" where the die has completely broken away at the rim). Common die crack examples have an estimated value around $50. More dramatic examples with extensive cracking or large rim cuds can command higher premiums.

Off-Center Strikes and Broadstrikes

Off-center strikes occur when the planchet is not properly centered between the dies during striking. The result is a coin where the design is shifted, with a blank crescent on one side. The value of off-center errors depends heavily on the percentage off-center and whether the date remains visible. Minor 5-10% off-center strikes might add $20 to $50 to the coin's value. Dramatic 40-60% off-center strikes with a full, visible date can be worth $500 or considerably more, as these are visually striking and clearly identifiable as errors.

Broadstrikes occur when the collar (the restraining ring that forms the coin's edge) fails to contain the planchet during striking. The coin spreads out beyond its normal diameter and typically has no reeded edge. Broadstrikes are less common than off-center strikes but typically command similar premiums based on their visual appeal and dramatic appearance.

Recent auction results provide valuable insight into the current market for 1940 Walking Liberty Half Dollars, particularly for high-grade examples where price guide values may lag behind actual market activity. Auction records from major houses confirm strong collector demand for premium-quality specimens.

For 1940 Philadelphia business strikes in MS-67, recent auction activity from 2022-2025 shows consistent results in the $500 to $700 range. Specific sales include $504, $552, and $660 realized prices for PCGS and NGC certified examples. This data demonstrates that the NGC Price Guide value of $700 more accurately reflects current market conditions than the PCGS guide value of $310. Examples grading MS-68 have sold for between $2,400 and $12,000, with the wide range reflecting variations in strike quality and eye appeal even within the same numerical grade.

The finest-known 1940 Philadelphia example, graded PCGS MS-68+ (population of one), achieved $29,375 at a Legend Rare Coin Auctions sale in September 2019. This exceptional result reflects the premium that top-population coins command from registry set collectors seeking the finest available examples.

For 1940-S San Francisco issues, auction records clearly demonstrate the dramatic value difference between typical weakly-struck examples and rare fully-struck specimens. A 1940-S graded MS-67 with a full, sharp strike sold for $35,250 at Heritage Auctions in 2013, setting a record for the issue. Stack's Bowers sold another fully-struck example for $13,200 in August 2020, noting in their catalog description that the 1940-S is "the rarest issue of this era in Gem condition" when properly struck. These results confirm that NGC's $10,000 guide value for MS-67 reflects the market for premium fully-struck examples, while PCGS's $265 guide applies only to typical weak-strike coins.

Proof coins have also shown strong auction results. In 2023, PF-67 examples sold for $750, $810, and $840, with a PCGS PF-67 carrying CAC (Certified Acceptance Corporation) approval achieving $1,020. Top-grade PF-68 examples have brought $3,600 (NGC) and $4,560 (PCGS) in recent sales, substantially above the NGC 2021 guide value of $1,175 and confirming strengthening demand for finest-grade proof examples.
