1921 Half Dollar: A Unique Year in U.S. Numismatics
The year 1921 represents one of the most significant periods in 20th-century U.S. coin collecting. Eight distinct half dollar issues were produced, making it the most complex single year for this denomination. Three Walking Liberty business strikes from Philadelphia, Denver, and San Francisco combine with five classic commemorative issues to create a remarkable collecting challenge.
Post-World War I economic recession drastically reduced business strike mintages, making all three Walking Liberty issues premier key dates of the 1916-1947 series. The lowest mintage belongs to the 1921-D at just 208,000 coins, while the 1921-S becomes the condition-rarity key in higher grades despite its higher mintage of 548,000. Meanwhile, five commemorative varieties—Pilgrim Tercentenary, Alabama (Plain and 2X2), and Missouri (Plain and 2*4)—add further complexity and collecting opportunities.
This comprehensive guide covers identification, authentication, grading, and current market values for all eight 1921 half dollar issues, with particular attention to the heavily counterfeited 1921-D and the intentional design varieties created to stimulate collector sales.

How to Identify 1921 Half Dollars
All 1921 half dollars share identical physical specifications: 90% silver composition, 12.50 grams weight, 30.6 mm diameter, and reeded edge. However, distinguishing between the eight issues requires attention to mint marks, design elements, and specific variety diagnostics.
Walking Liberty Business Strikes
Designed by Adolph A. Weinman, the Walking Liberty half dollar features Liberty striding left holding laurel and oak branches on the obverse, with an eagle perched on a mountain ledge on the reverse. The mint mark location is critical for identification: the 'D' or 'S' mint mark appears on the reverse, in the lower-left field, below the pine branch and to the left of the rock. The 1921 Philadelphia issue bears no mint mark.

Strike quality varies significantly by mint. The 1921-P typically exhibits sharp, well-defined features throughout. In contrast, the 1921-D and 1921-S are notoriously weakly struck, particularly on Liberty's left hand, skirt lines, and the eagle's breast feathers. Collectors must distinguish between strike weakness and actual circulation wear when evaluating these coins.
Commemorative Issues
All five 1921 commemorative half dollars were struck at Philadelphia and bear no mint mark. The Pilgrim Tercentenary features Governor William Bradford on the obverse and the Mayflower on the reverse. The Alabama Centennial displays jugate busts of Governors William Bibb and Thomas Kilby on the obverse (making it the first U.S. coin to depict a living person) with the Alabama state seal on the reverse. The Missouri Centennial shows a frontiersman bust (identified as Daniel Boone) on the obverse with a standing frontiersman and Native American on the reverse.
The key diagnostic for Alabama varieties is the small incuse '2X2' marking in the right obverse field, above the 22 stars, which appears only on 6,006 specimens. The Plain variety (59,038 mintage) lacks this marking. For Missouri varieties, the diagnostic is the small incuse '2*4' in the left obverse field, left of the bust, which appears on only 5,000 specimens. The Plain variety (15,428 mintage) lacks this marking. These markings were intentionally created to manufacture scarcity and stimulate collector sales.

1921 Half Dollar Price Guide
The 1921 half dollar market demonstrates significant value stratification based on mint mark, variety, and condition. All prices reflect November 2025 retail values sourced from PCGS, NGC, APMEX, and CoinWorld price guides, supplemented by recent auction results. The intrinsic silver melt value of approximately $17.18 is consistently superseded by numismatic premiums across all issues and grades.
1921 (P) Walking Liberty Half Dollar
Mintage: 246,000 | Key Status: Second-lowest mintage in series, key date in all grades
The Philadelphia issue benefits from characteristically sharp strikes and was saved in slightly greater numbers than branch mint counterparts. While scarce in circulated grades, it becomes exceedingly rare in Mint State. A PCGS MS-66 achieved $54,050 at a 2015 auction, demonstrating strong demand for top-population examples.
| Grade | Value Range |
|---|---|
| G-4 | $125 – $175 |
| VF-20 | $800 – $915 |
| EF-40 | $2,000 – $2,905 |
| AU-50 | $3,000 – $4,105 |
| MS-60 | $7,000 – $8,325 |
| MS-63 | $8,000 – $10,000 |
| MS-65 | $27,500 – $29,950 |
Recent Auction Results: PCGS VF-30 (CAC) sold for $950 (Jan 2021); PCGS MS-62 realized $4,080 (Stack's Bowers, May 2025)
1921-D (Denver) Walking Liberty Half Dollar
Mintage: 208,000 | Key Status: Lowest mintage in entire series, premier key date in circulated grades
The 1921-D represents the ultimate Walking Liberty rarity in low grades, commanding substantial premiums even in Good-4. Expert estimates suggest only 275 to 375 uncirculated specimens survive across all mint state grades. This issue is one of the most heavily counterfeited 20th-century U.S. coins—authentication by a reputable third-party grading service is essential. Strike weakness on central features is typical and should not be confused with wear.
| Grade | Value Range |
|---|---|
| G-4 | $225 – $330 |
| VF-20 | $1,250 – $1,750 |
| EF-40 | $3,750 – $4,410 |
| AU-50 | $5,500 – $6,668 |
| MS-60 | $8,500 – $10,790 |
| MS-63 | $10,000 – $16,000 |
| MS-65 | $45,000 – $55,495 |
Recent Auction Results: PCGS G-4 sold for $192 (Stack's Bowers, Jan 2023); NGC G-6 sold for $288 (Heritage, May 2023); PCGS AU-58 (CAC) realized $12,600 (Heritage, Oct 2025); PCGS MS-64 realized $27,600 (Stack's Bowers, Jun 2021)
1921-S (San Francisco) Walking Liberty Half Dollar
Mintage: 548,000 | Key Status: Condition-rarity key—rarest and most valuable in grades VF-20 and higher
The 1921-S presents a fascinating rarity inversion. In G-4 grade, it is the most affordable 1921 Walking Liberty at $50-$90. However, poor contemporary saving resulted in heavy circulation that destroyed the vast majority of the uncirculated population. In VF-20 and higher grades, the 1921-S becomes rarer and more valuable than the lower-mintage 1921-D. This condition rarity makes it the premier Walking Liberty key date in mint state, with the auction record standing at $188,000 for a PCGS MS-66.
| Grade | Value Range |
|---|---|
| G-4 | $50 – $90 |
| VF-20 | $775 – $849 |
| EF-40 | $3,250 – $4,500 |
| AU-50 | $8,000 – $18,000 |
| MS-60 | $20,000 – $22,500 |
| MS-63 | $27,500 – $41,500 |
| MS-65 | $50,000 – $125,000 |
Recent Auction Results: PCGS AG-03 sold for $36 (PCGS); NGC F-15 sold for $360 (NGC); PCGS MS-66 achieved auction record of $188,000 (Heritage, Jun 2016)
Grade comparison: G-4 shows heavy wear with date barely visible; VF-20 shows moderate wear with visible skirt lines; MS-65 displays full mint luster
1921 Pilgrim Tercentenary Commemorative
Mintage: 20,053 (net after 80,000 melted) | Designer: Cyrus E. Dallin
The Pilgrim Tercentenary presents a complex mintage history. Originally 100,053 coins were struck, but 80,000 were returned to the Mint and melted, leaving only 20,053 in collectors' hands. This melting event is the key to its scarcity. The obverse features Governor William Bradford, while the reverse depicts the Mayflower. This issue is distinguished from the 1920 Pilgrim half dollar by the date appearing on the obverse.
| Grade | Value Range |
|---|---|
| AU-50 | $180 |
| MS-63 | $225 – $245 |
| MS-65 | $375 – $550 |
| MS-67 | $1,400 – $2,650 |
Recent Auction Results: PCGS MS-65 sold for $276 (Heritage, Nov 2023)
1921 Alabama Centennial (Plain)
Mintage: 59,038 | Designer: Laura Gardin Fraser
The Plain variety lacks the '2X2' marking and was marketed to the general public rather than specifically to collectors. Many were subsequently spent during the Great Depression, resulting in higher attrition rates than the scarce 2X2 variety. The obverse features jugate busts of Governors William Bibb and Thomas Kilby, while the reverse displays the Alabama state seal.
| Grade | Value Range |
|---|---|
| AU-50 | $125 |
| MS-60 | $240 |
| MS-63 | $350 |
| MS-65 | $600 – $700 |
Recent Auction Results: PCGS XF-45 sold for $92.40 (PCGS); PCGS MS-67 realized $14,400 (Heritage, May 2022)
1921 Alabama Centennial (2X2)
Mintage: 6,006 | Designer: Laura Gardin Fraser
The 2X2 variety features a small incuse '2X2' in the right obverse field, above the 22 stars, signifying Alabama as the 22nd state. This scarce variant was created specifically to appeal to collectors and was saved in higher grades at greater rates than the Plain variety. Despite a mintage ratio of nearly 10-to-1 (Plain to 2X2), their values in MS-63 are only 1.3-to-1, indicating that surviving populations in collectible grades are much closer than mintage figures suggest.
| Grade | Value Range |
|---|---|
| AU-50 | $250 |
| MS-60 | $320 |
| MS-63 | $450 – $485 |
| MS-65 | $725 – $1,050 |
| MS-67 (CAC) | $21,000 |
Recent Auction Results: NGC XF-45 sold for $135 (PCGS); PCGS MS-65 realized $960 (Stack's Bowers, Jun 2025); PCGS MS-66 sold for $1,800 (Heritage, Jan 2025); PCGS MS-67 (CAC) achieved $21,000 (Heritage, Jan 2023)
1921 Missouri Centennial (Plain)
Mintage: 15,428 | Designer: Robert Aitken
The Plain variety lacks the '2*4' marking. Interestingly, the '2*4' die was created first, and the marking was subsequently polished off the die to create the Plain variety. The obverse features a frontiersman bust identified as Daniel Boone, while the reverse depicts a standing frontiersman and Native American.
| Grade | Value Range |
|---|---|
| AU-50 | $295 |
| MS-60 | $435 |
| MS-63 | $835 – $860 |
Recent Auction Results: Premium-quality PCGS MS-66 (CAC) sold for $10,249.88 (GreatCollections)
1921 Missouri Centennial (2*4)
Mintage: 5,000 | Designer: Robert Aitken
The 2*4 variety features a small incuse '2*4' in the left obverse field, left of the bust, signifying Missouri as the 24th state. At just 5,000 pieces, this is the scarcest of all 1921 half dollar issues. Like the Alabama 2X2, it was marketed specifically to collectors and survives in higher grades at disproportionate rates compared to its Plain counterpart.
| Grade | Value Range |
|---|---|
| AU-50 | $520 |
| MS-60 | $750 |
| MS-63 | $1,150 – $1,200 |
| MS-65 | $1,980 – $3,700 |
Recent Auction Results: PCGS MS-66 sold for $4,440 (Stack's Bowers, Aug 2021)
Grading 1921 Half Dollars
Accurate grading is essential for valuing 1921 half dollars, as small grade differences translate to significant price variations. The challenge is compounded by strike weakness on many 1921-D and 1921-S Walking Liberty issues, where collectors must distinguish between strike characteristics and actual circulation wear. This section covers key diagnostics for the major grade levels.
Good (G-4): Heavy wear throughout. On Walking Liberty issues, Liberty's body shows as a flat outline with no interior detail. The date and lettering remain visible but may be weak. On commemoratives, major design elements are identifiable but details are significantly worn.
Very Fine (VF-20): Moderate to considerable wear. On Walking Liberty issues, Liberty's skirt lines are visible but worn flat in the center. The eagle shows moderate detail in the feathers. For commemoratives, design details are clear but worn in high points. This is a critical grade level where the 1921-S Walking Liberty begins to demonstrate its condition rarity premium.
Strike quality comparison: weak strike (common on 1921-D and 1921-S) shows flat central details; strong strike (typical on 1921-P) shows full definition
Extremely Fine (EF-40): Light wear on high points only. Liberty's skirt lines are mostly complete except at the very center. The eagle's breast and leg feathers show considerable detail. Original luster may begin to appear in protected areas. For commemoratives, only slight wear appears on the highest design elements.
About Uncirculated (AU-50 to AU-58): Traces of light wear on the highest points. On Walking Liberty issues, check Liberty's left hand, breast, and left leg for friction. On the reverse, examine the eagle's breast and left leg. The coin retains considerable mint luster (50-90%). For commemoratives, check the highest relief points of portrait busts and figures for slight friction.
Mint State (MS-60 to MS-70): No trace of wear. The coin must show full original luster, though it may be diminished by contact marks or poor strike quality. MS-60 coins show numerous heavy marks and possibly impaired luster. MS-63 shows scattered marks but acceptable eye appeal. MS-65 displays minimal marks and strong eye appeal. MS-67 and higher represent exceptional preservation with virtually flawless surfaces.
The critical distinction for 1921-D and 1921-S Walking Liberty issues is identifying weak strike versus wear. A weakly struck MS-63 may show flat details on Liberty's hand and skirt that resemble AU wear. However, a weakly struck coin will still display full mint luster in fields and protected areas. Genuine AU wear creates friction and luster breaks on high points. When in doubt, seek professional authentication from PCGS or NGC.
For commemoratives, strike quality is generally uniform and sharp. Grading focuses on contact marks, surface quality, and original luster. The Plain varieties of Alabama and Missouri often show more wear and problems compared to the scarce 2X2 and 2*4 varieties, which were more carefully preserved by collectors.
Authentication and Counterfeit Detection
The 1921-D Walking Liberty Half Dollar ranks among the most heavily counterfeited 20th-century U.S. coins due to its low mintage and high values across all grades. Modern counterfeits, often originating from Asia, have become increasingly sophisticated, making professional authentication essential for any 1921-D purchase. The 1921-P, 1921-S, and commemorative issues also face counterfeit threats, though to a lesser degree.
⚠️ Critical Warning
Never purchase a 1921-D Walking Liberty Half Dollar without third-party certification from PCGS, NGC, or another reputable grading service. The prevalence of counterfeits makes ungraded examples extremely risky, regardless of price.
Modern counterfeits exhibit several diagnostic features. First, examine surface details carefully. Many fakes show a 'fuzzy' or soft appearance, particularly on peripheral letters (IN GOD WE TRUST, UNITED STATES OF AMERICA) and the stars within the flag behind Liberty. Genuine coins, even when worn, display sharper, more distinct features. Second, look for copied abrasions. Counterfeit dies are often made from genuine circulated coins. Any scratches, nicks, or 'lint marks' on the host coin transfer to the die, causing these non-mint-made marks to appear on every fake struck from that die. Identical, repeating surface marks across multiple examples are definitive signs of counterfeits.
Counterfeit detection: genuine coins show sharp peripheral letters and distinct flag stars; fakes exhibit fuzzy, soft appearance
Third, assess luster quality. Genuine Walking Liberty half dollars display a characteristic 'cartwheel' luster pattern—a band of light that rotates across the coin's surface when tilted. Counterfeits often show odd or unnatural luster, including strange die polish lines (such as horizontal lines across Liberty's body) not seen on genuine examples. Weight verification provides an additional check: genuine 1921 half dollars weigh 12.50 grams. Underweight coins are immediate red flags.
A known contemporary counterfeit (a fake made in 1921 to circulate as money) exists for the 1921-P. Part of the 'Fat Motto family,' it is deceptively made of silver (possibly sterling) but is significantly underweight at an average of 11.5 grams versus the 12.50-gram standard. This weight discrepancy is the key diagnostic for detecting this specific counterfeit type.
For commemorative issues, counterfeits are less common but not unknown. The Alabama 2X2 and Missouri 2*4 varieties face particular risk due to their scarcity and premium values. Verify that the incuse '2X2' or '2*4' markings appear sharp and properly positioned. Weak or poorly defined variety markings may indicate a cast counterfeit or altered Plain variety.
Cleaned coins present another authentication challenge. Improper cleaning strips the original mint surface and destroys numismatic value. Signs of cleaning include fine parallel or swirling hairline scratches in the fields, unnatural brightness or dullness, loss of the cartwheel luster effect, and blotchy or uneven coloration from chemical treatments. Grading services designate cleaned coins as 'Details' grades (e.g., 'EF Details - Cleaned'), which significantly reduces value. A cleaned coin cannot achieve straight numerical grades and trades at substantial discounts compared to problem-free examples.

Preserving Your 1921 Half Dollars
All 1921 half dollars contain 90% silver and 10% copper, making them susceptible to environmental damage over time. Proper storage and handling are essential for maintaining both condition and value. Silver naturally tones when exposed to sulfur compounds in the air, developing color that ranges from light gold to deep charcoal. Original, natural toning is generally acceptable to collectors and can even enhance value when attractively displayed. However, artificial toning, PVC damage, or active corrosion significantly reduces value.
Store coins in a stable environment with moderate temperature (60-70°F) and low humidity (30-50%). Avoid attics, basements, or areas subject to temperature fluctuations. Use only archival-quality, inert holders such as Mylar flips or acrylic capsules specifically designed for coin storage. Never use soft, flexible PVC flips, as they contain plasticizers that migrate to the coin's surface, causing green slime residue that permanently damages silver. This PVC contamination is irreversible and destroys numismatic value.
When handling coins, hold them by the edges only. Avoid touching obverse or reverse surfaces, as skin oils contain acids that cause fingerprints to etch into silver over time. These etched fingerprints cannot be removed and constitute permanent surface damage. For high-value coins such as the 1921-D Walking Liberty or scarce commemorative varieties, consider wearing cotton gloves during handling to prevent any oil transfer.
Never attempt to clean coins. Even gentle methods strip the original surface and create hairline scratches that professional graders immediately identify. A cleaned coin cannot achieve straight numerical grades from PCGS or NGC and trades at steep discounts. If a coin appears dirty or has accumulated environmental contaminants, consult a professional conservation service affiliated with a major grading company rather than attempting home cleaning.
For maximum protection and value preservation, submit valuable 1921 half dollars to professional third-party grading services such as PCGS or NGC. Certified encapsulation in sonically-sealed holders provides museum-quality protection against environmental damage while also providing authentication and grade verification. This is particularly critical for the heavily counterfeited 1921-D Walking Liberty and for any high-grade specimens.
1921 Half Dollar Mint Errors
Major mint errors (off-center strikes, wrong planchet errors, brockages) are exceptionally rare on 1921 half dollars, and the market for such pieces is thin with limited pricing data. No significant, widely-traded error types are documented in authoritative error coin price guides for this year and denomination.
One documented example is a 1921 Alabama 2X2 half dollar graded ANACS AU-58 Details for a 'Planchet Crack'—a minor flaw in the planchet that occurred before striking. Planchet cracks are relatively common minor errors that add minimal premium to a coin's value. The value remains primarily tied to the base coin rather than the error itself.
Any major error on a 1921-D or 1921-S Walking Liberty (such as 20%+ off-center strike, struck on wrong planchet, or major die break) would represent a significant numismatic discovery and command thousands or tens of thousands of dollars at a major auction. However, without specific documented examples and auction results, providing reliable price ranges is not possible. Collectors who believe they possess a major 1921 half dollar error should submit it to a reputable third-party grading service with error coin expertise for authentication and attribution.
Recent Auction Highlights
Recent auction results demonstrate the strong market for premium-quality 1921 half dollars across all issues. Notable sales from 2021-2025 include:
Walking Liberty Business Strikes: A PCGS MS-62 1921-P realized $4,080 (Stack's Bowers, May 2025), demonstrating sustained demand even for choice uncirculated examples. For the 1921-D, an NGC G-6 sold for $288 (Heritage, May 2023), while a premium PCGS AU-58 (CAC) commanded $12,600 (Heritage, October 2025). A top-quality PCGS MS-64 1921-D achieved $27,600 (Stack's Bowers, June 2021), highlighting the substantial premiums for higher-grade specimens.
Commemoratives: The commemorative market shows strong performance for high-grade examples. A PCGS MS-67 1921 Alabama Plain realized $14,400 (Heritage, May 2022), while a PCGS MS-67 (CAC) Alabama 2X2 achieved $21,000 (Heritage, January 2023). For Missouri varieties, a premium PCGS MS-66 (CAC) Plain sold for $10,249.88 (GreatCollections), and a PCGS MS-66 2*4 brought $4,440 (Stack's Bowers, August 2021).
These results confirm that the market rewards original, problem-free examples with strong eye appeal. CAC (Certified Acceptance Corporation) stickered coins command significant premiums, often 20-50% above non-CAC examples of the same grade. Additionally, PCGS-graded coins frequently realize higher prices than equivalent NGC examples for key dates such as the 1921-D, reflecting market preferences for certain certification brands.
Frequently Asked Questions
How much is my 1921 half dollar worth?
Value depends on which of the eight 1921 half dollar issues you have and its condition. The most affordable is the 1921-S Walking Liberty in G-4 at $50-$90. The most expensive is the 1921-S Walking Liberty in MS-65 at $50,000-$125,000. For Walking Liberty issues, check the mint mark on the reverse (no mark = Philadelphia, 'D' = Denver, 'S' = San Francisco). For commemoratives, identify which design you have (Pilgrim, Alabama Plain, Alabama 2X2, Missouri Plain, or Missouri 2*4) and reference the price tables in this guide.
How do I identify the mint mark on a 1921 Walking Liberty half dollar?
The mint mark appears on the reverse (back), in the lower-left field, below the pine branch and to the left of the rock. A 'D' indicates Denver, an 'S' indicates San Francisco, and no mint mark indicates Philadelphia. Use magnification if needed, as the mint mark is small. This location is consistent across all Walking Liberty half dollars from 1916-1947.
Why is the 1921-S more valuable than the 1921-D in high grades?
This is a classic example of condition rarity versus mintage rarity. The 1921-D has a lower mintage (208,000 vs 548,000) and is indeed more valuable in low circulated grades like G-4. However, the 1921-S was not widely saved by collectors at the time and circulated heavily, destroying most uncirculated examples. In grades of VF-20 and higher, far fewer 1921-S specimens survive compared to the 1921-D, making it rarer and more valuable in mint state despite the higher original mintage.
What are the Alabama 2X2 and Missouri 2*4 varieties?
These are intentional design varieties created specifically to stimulate sales to collectors. The Alabama 2X2 (mintage 6,006) features a small incuse '2X2' in the right obverse field, signifying Alabama as the 22nd state. The Missouri 2*4 (mintage 5,000) features a small incuse '2*4' in the left obverse field, signifying Missouri as the 24th state. These marked varieties are scarcer and more valuable than their Plain counterparts and were marketed specifically to collectors rather than the general public.
Should I get my 1921 half dollar professionally graded?
For any 1921-D Walking Liberty, professional grading is essential due to the prevalence of counterfeits. For other 1921 issues, grading is recommended if the coin appears to be AU or better, or if you plan to sell it. PCGS and NGC certification provides authentication, preserves the coin, and typically increases marketability and selling price. The grading fee (typically $30-$75 depending on service level and declared value) is worthwhile for coins valued over $200-$300. Lower-grade circulated examples may not justify the expense unless authentication concerns exist.
Is the silver melt value significant for 1921 half dollars?
No. With 0.3617 troy ounces of silver, the melt value is approximately $17.18 (based on November 2025 silver prices). Even the least valuable 1921 half dollar—the 1921-S in G-4—trades for $50-$90, representing a 300-500% premium over melt. The numismatic (collector) value consistently and significantly exceeds the intrinsic metal value across all issues and grades. Melt value merely represents the absolute floor price.
How can I tell if my 1921-D is counterfeit?
Examine surface details carefully. Counterfeits often show a 'fuzzy' or soft appearance, especially on peripheral letters and the stars in the flag behind Liberty. Look for identical repeating scratches or marks across the surfaces—these indicate the counterfeit die was made from a worn genuine coin. Check for unnatural luster or strange die polish lines. Verify the weight: genuine coins weigh 12.50 grams. However, the safest approach is to only purchase 1921-D specimens that are already certified by PCGS, NGC, or another reputable grading service.
What is the difference between weak strike and wear?
This distinction is critical for 1921-D and 1921-S Walking Liberty issues, which often show weak strikes. A weakly struck coin will have flat or undefined details in the center (Liberty's hand, skirt lines, eagle's breast) but will still display full mint luster in the fields and protected areas—indicating no circulation. A worn coin will show friction and luster breaks on the high points where the coin contacted other surfaces during circulation. When details are flat AND luster is intact, it's a strike issue. When details are flat AND luster is broken, it's wear.
Can I clean my 1921 half dollar to improve its appearance?
Never clean coins. Even gentle cleaning methods strip the original mint surface and create hairline scratches that professional graders immediately identify. Cleaned coins receive 'Details' grades (e.g., 'AU Details - Cleaned') from PCGS and NGC, which dramatically reduces value—often by 50% or more compared to an uncleaned example. If a coin appears dirty or has environmental damage, consult a professional conservation service rather than attempting home cleaning.
Were proof versions of 1921 half dollars produced?
No. No proof, specimen, or special finish half dollars were produced by the U.S. Mint in 1921. The Walking Liberty Proof series was not introduced until 1936. All 1921 half dollars—both Walking Liberty business strikes and commemoratives—are regular business strike issues. Any 1921 half dollar advertised as 'proof' is either mislabeled, improperly cleaned to appear proof-like, or fraudulent.

Mintage figures are cross-referenced across multiple sources, with discrepancies noted where they occur. For commemorative issues, net mintage (coins actually distributed) is cited rather than gross mintage (total struck), as significant numbers of commemoratives were returned to the Mint and melted.
Coin values fluctuate based on precious metal prices, market demand, and economic conditions. The prices cited represent market ranges as of November 2025 and should be considered estimates rather than exact values. Actual selling prices vary based on specific coin quality, eye appeal, certification service, and individual transaction circumstances. For current values, consult recent auction results or obtain professional appraisals from certified numismatic experts.
