2021 Washington Quarter Errors: Value Guide & Rare Varieties
What is a 2021 Washington Quarter error worth? The Crown die chip pays $10–$35 raw, the 3 Oar WDDR-003 up to $75 graded, and a Missing Clad Layer $20–$300+. Avoid machine doubling traps. Verified values as of January 2026.
Most 2021 Washington Quarters are worth face value, but three verifiable errors pay real money: the "Crown" die chip ($10–$35 raw), the "3 Oar" WDDR-003 doubled die ($45–$75 graded), and a Missing Clad Layer ($20–$300+).
- 🎯 Most Common Find: "Crown" die chip on Crossing the Delaware — raised lump on Washington's tricorn hat
- 🎯 Top Variety: 2021-P "3 Oar" WDDR-003 — ghost oar shaft below the primary oar in the boat scene ($5–$75)
- 🎯 Major Error: Missing Clad Layer — copper-colored face and coin weighs only ~4.7–5.1g ($20–$300+)
- 🚫 No 2021-W Exists: The West Point quarter program ended in 2020 — do not search 2021 rolls for it
⚠️ Machine Doubling (flat, shelf-like doubling on the date or mottos) is the #1 trap on this year — it carries zero premium. Use a 10x loupe to tell the difference.

Check your coin for valuable errors and varieties
Values shown are typical retail estimates as of 2026-01.
Error coin values vary significantly based on grade, eye appeal, severity, and current market conditions.
Professional authentication (PCGS/NGC) is recommended for any coin suspected to be worth $25 or more.
Machine Doubling (flat, shelf-like doubling) is NOT a valuable error and commands no premium.
No 2021-W (West Point) quarters were minted for circulation. The W-mintmark program concluded in 2020.
A 2021 quarter with no visible mint mark is likely a struck-through-grease minor error, not a major rarity. Philadelphia coins carry a P mint mark.
Die chips and die breaks are valued primarily by size and severity — small Stage 1 bud chips are generally face value only.
In 2021 the U.S. Mint struck two entirely different quarter designs in a single calendar year — the final America the BeautifulTuskegee Airmen issue and the one-year Crossing the Delaware commemorative. With more than 2.1 billion clad coins struck at Philadelphia and Denver combined, rarity is not this year's story. Specific, verifiable errors are — and finding the right ones still pays real money.

⚠️ The 2021-W Quarter Does NOT Exist
The West Point Mint's "Great American Coin Hunt" W-quarter program ran 2019–2020 only. No 2021-W quarters were produced for circulation. Coin World confirms the program did not continue into 2021. Any listing claiming a 2021-W is factually incorrect.

2021 Washington Quarter Quick Checks: 3 Errors Worth Hunting
Run these three checks on every 2021 quarter before spending it. The trap card at the end covers the single most common false alarm on this year — Machine Doubling — which fools thousands of sellers every month.
Check 1: "Crown" Die Chip on Washington's Hat
Reverse of the Crossing the Delaware quarter only. Focus on General Washington's tricorn hat in the boat scene — specifically the upper ridge and crown of the hat.
A raised, irregular lump of metal on the hat top. It must be in relief (sticking up above the surface). The more of the hat it covers, the more it's worth: Stage 2 (~25–40% coverage) = $2–$5; Stage 3 "Full Crown" (>75%) = $10–$35.
Dents or gouges pressed into the metal are post-mint damage (PMD). Mushy or weak hat detail is die deterioration, not a chip. Tiny Stage 1 "bud" chips (a pinpoint dot) are essentially face value.
Check 2: "3 Oar" Doubled Die Reverse (WDDR-003) — 2021-P Only
Reverse of the 2021-P Crossing the Delaware quarter only. Examine the oars held by Washington's boatmen in the river scene under a 10x loupe.
A distinct ghost oar shaft appearing directly below the primary oar — as if a third oar is floating in the water. The secondary image is rounded and raised, with similar relief to the primary oar. This is a Class VIII Tilted Hub doubled die.
Machine Doubling creates flat, step-like shelves beside design elements — not a distinct floating oar shaft. Die erosion causes overall mushy details everywhere, not a separate crisp secondary image on one element.
Check 3: Feeder Finger Scrapes
Flat, open reverse fields on both designs. On the Tuskegee Airmen quarter, look near the control tower and P-51 Mustangs. On the Delaware quarter, examine the sky and water areas. Rotate the coin under a light to reveal raised lines.
Perfectly parallel, raised straight lines in the fields. The critical authentication test: design devices (letters, portraits) must sit on top of the lines, interrupting them — the lines pass under the devices and resume on the other side. This proves the damage was on the die itself.
Post-mint scratches cut through design elements and often have furrow-like raised ridges on the sides. Random bag-contact hairlines are not perfectly parallel. Any line that gouges through Washington's face is damage, not a die error.
Trap: Machine Doubling — The #1 False Alarm on 2021 Quarters
Date "2021", "LIBERTY", "IN GOD WE TRUST", and "QUARTER DOLLAR". Machine Doubling (MD) is present on a large percentage of 2021 quarters due to high-speed production.
If the secondary image looks like a flattened step or shelf beside the primary — making letters appear smaller or thinner — it is Machine Doubling. A true Doubled Die (DDO/DDR) creates a rounded, raised secondary image with notched corners on the serifs.
Machine Doubling is NOT a recognized numismatic variety. Never pay a premium for it. It is a mechanical production artifact caused by the die shifting slightly as it retracts from the coin.
2021 Washington Quarter Errors: Value Reference Table
This table aggregates verified errors for the 2021 Washington Quarter. Only varieties with established diagnostics and documented auction results are included in the top block. Minor and unverified listings follow for reference.
Verified Major Errors
| Error Type | Designation | Mint | Rarity | Value Range (Raw) | Value Range (MS65/66) | Auction Record |
|---|---|---|---|---|---|---|
| "3 Oar" DDR (WDDR-003) | WDDR-003 | P | Scarce | $5–$15 | $45–$75 | ~$100 |
| "Crown" Die Chip (Stage 3) | Progressive IDB | P / D | Common–Scarce | $2–$35 | $25–$50 | ~$40 (MS66) |
| Feeder Finger Scrapes | — | P / D | Uncommon | $3–$15 | $15–$30 | N/A |
| Missing Clad Layer | Major Error | P / D | Rare | $20–$50 | $100–$300 | $300+ |
| Struck Through Grease | — | P / D | Variable | $2–$20 | $30–$60 | Variable |
Minor & Unverified Listings (Market Watch)
| Variety Name | Category | Design | Market Status | Value |
|---|---|---|---|---|
| "Drooling" Washington | Die Chip | Both | Common / Novelty | ~$1 |
| "Burning Building" | Die Chip | Tuskegee | Niche collector interest | $2–$5 |
| "Extra Wing" (P-51) | Die Chip | Tuskegee | Minor / Nominal | $1–$2 |
| "Doubled Ear" | Unverified | Both | Usually MD or die erosion — verify before paying | Face value |
S-Mint Proof Values
San Francisco proof quarters come in two compositions. Weigh your coin to determine which you have before estimating value.
| Type | Weight | Design | PF69 Value | Notes |
|---|---|---|---|---|
| Clad Proof | 5.67g | Tuskegee / Delaware | $10+ | From annual Proof Set |
| Silver Proof (99.9% Ag) | 6.25g | Tuskegee / Delaware | $10+ | Heavier than clad — weigh to confirm |
| NIFC Business Strike | 5.67g | Tuskegee / Delaware | $5+ | From Mint Sets; not struck for circulation |
ℹ️ "Silver" Coins Found in Circulation
If a 2021 quarter appears silver but weighs 5.67g, it is almost certainly a plated clad coin (post-mint alteration) and worth face value only. A genuine silver proof (99.9%) weighs 6.25g. Weight is the definitive test.
2021 Washington Quarter Rare Errors & Varieties: Detailed Guides
These five errors have verified diagnostics and documented auction premiums. Each entry covers exactly what to look for, how to rule out fakes, and what the market currently pays.
2021-P "3 Oar" Doubled Die Reverse (WDDR-003)
Normal single oar (left) vs. WDDR-003 with distinct ghost oar shaft below the primary (right).
Origin & Background
This variety affects only the 2021-P Crossing the Delaware quarter. It is classified as a Class VIII (Tilted Hub) doubled die — during the hubbing process (where the master hub stamps its design into the working die), the hub was slightly tilted, impressing a secondary off-angle image into the die steel. Modern "single-squeeze" hubbing was designed to prevent this, but Class VIII doubling persists when the hub or die assembly shifts during application. Because the doubling is in the die itself, every coin struck from that die carries the variety permanently.
How to Identify
- Examine the oars held by the boatmen on the reverse under a 10x loupe.
- On a normal coin, the oars are singular, sharp shafts. On WDDR-003, there is a distinct, separate oar shaft directly below the primary oar — a "ghost oar" floating in the water.
- The secondary oar is rounded and raised with similar relief to the primary — not flat or shelf-like.
- Compare against a known normal specimen to confirm; the extra shaft is unmistakable under magnification.
False Positives to Avoid
Machine Doubling creates flat, stepped shelves beside design elements — the secondary image is flattened and lower, not a distinct separate oar. Die erosion produces overall mushy details across the entire reverse, not a crisp isolated secondary shaft on one element. If the oar area looks generally mushy rather than showing a sharp secondary shaft, you have die deterioration, not WDDR-003.
Market Values
- $5–$15 — Raw circulated
- $45–$75 — MS65/MS66 certified
Auction Record
~$100 for a high-grade example. Because this is a permanent die variety (not a mechanical error), it retains numismatic value and appeals to Wexler set collectors.
2021 "Crown" Die Chip — Crossing the Delaware
Normal hat (left) vs. Stage 3 Full Crown die chip (right) — a large raised lump covering most of the hat top.
Crown die chip progression: Stage 1 'Bud' (face value) → Stage 2 'Half Crown' ($2–$5) → Stage 3 'Full Crown' ($10–$35).
Origin & Background
This is a result of die fatigue and spalling. The area of the die corresponding to Washington's hat is a point of deep recess (high relief on the coin). As the die strikes tens of thousands of copper-nickel planchets — a notoriously hard alloy — the steel in the deepest recess undergoes extreme stress cycles. Small pieces of die steel eventually fracture and break away (spall). Metal from the next struck planchet flows into that void, creating a raised, irregular lump on every subsequent coin. This error is progressive: the fracture grows with each strike.
How to Identify — Stage Scale
- Stage 1 "Bud": Tiny pinpoint dot on the very top edge of the hat. Face value only.
- Stage 2 "Half Crown": Chip extends along the brim, covering ~25–40% of the hat top. Worth $2–$5 raw.
- Stage 3 "Full Crown" / "Bird's Nest": Massive raised lump covering >75% of the hat top, often irregular and jagged. Worth $10–$35 raw; up to $50 certified MS66.
- Stage 4 "Cud" (theoretical): Break extends to the rim, creating a retained cud. $50+ — a major find.
⚠️ Value Is All About Size
Sellers frequently hype tiny Stage 1 chips as "rare errors." A pinpoint bud is face value. Only Stage 3 Full Crown chips are genuinely tradeable. Prices for Stage 3 specimens settled to $10–$35 (raw) after an initial speculative spike. A PCGS/NGC-graded MS66 example can reach $50–$80. Verify size before submitting for grading — the ~$30–$50 grading cost often exceeds the raw value.
False Positives to Avoid
Any mark pressed into the surface (dents, gouges, divots) is post-mint damage — likely from contact with other coins or machinery. A genuine die chip is always raised (in relief). "Mushy" hat detail with soft, indistinct lines is Late Die State (LDS) die deterioration — common and worth face value.
Market Values
- $0.25 — Stage 1 Bud
- $2–$5 — Stage 2 Half Crown (raw)
- $10–$35 — Stage 3 Full Crown (raw)
- $25–$50 — Stage 2/3 certified MS65/MS66
Auction Record
~$40 for a MS66 example. Referenced listing: Nasser Road Online — Progressive Crown Die Chip.
2021 Feeder Finger Scrapes
Feeder finger scrapes: parallel raised lines pass under design devices — proving the damage was on the die, not the coin.
Origin & Background
The U.S. Mint uses high-speed Schuler presses capable of striking up to 750 coins per minute. Automated "feeder fingers" slide blank planchets into the striking collar just before impact. If the press timing drifts even by milliseconds, or if the finger mechanism loosens, the metal finger grazes across the face of the anvil die (typically the reverse die) before retracting. Because the die itself is now scratched, every coin struck afterward carries raised parallel lines — the metal flows into the die scratches during striking.
How to Identify
- Look for perfectly straight, parallel raised lines in the open reverse fields under directional light.
- Most visible on the Tuskegee Airmen reverse due to its large sky and ground fields. Also present on the Delaware design's sky and water areas.
- The authentication test: rotate the coin and watch the lines disappear behind a raised device (lettering, control tower, portrait) and reappear on the other side. Lines passing under devices prove they are on the die — not on the coin.
- Severity determines value: light lines (faint hairlines) = nominal; heavy deep channels = $5–$15.
False Positives to Avoid
Post-mint scratches cut through design elements and leave raised furrow ridges on the sides. Bag-contact hairlines are random, not perfectly parallel. A coin struck on a detached aluminum feeder finger tip is an entirely separate catastrophic error — a wrong-planchet strike worth $3,000+ — distinct from these common scrape lines.
Market Values
- $0 premium — Light (faint lines visible only under tilt)
- $3–$8 — Medium (lines visible to the naked eye)
- $5–$15 — Heavy (deep channels obscuring significant field area)
- $15–$30 — Certified MS65/MS66
2021 Missing Clad Layer
Missing clad layer: copper-colored surface (right) vs. normal silver-clad quarter (left) — confirmed by underweight at ~4.7g.
Origin & Background
Standard clad quarters are physically a "sandwich" — a pure copper core bonded between outer nickel-silver layers. If one of those outer layers is missing before striking (due to a defective planchet that never received its cladding), the struck coin exposes the stark copper core on one face. Both the dramatic color change and the significant weight loss are required for authentic attribution. This is a genuine planchet error, not die damage.
How to Identify
- One face of the coin is distinctly copper-red or reddish-brown instead of the normal silver-gray.
- Weigh the coin: A normal clad quarter is 5.67g. A missing-clad-layer coin weighs approximately 4.7–5.1g. Both criteria must be met.
- The edge may show an asymmetric clad layer — the copper core visible on the stripped side.
- The design details on the affected face may still be sharp and normal; only the color and weight betray it.
False Positives to Avoid
Plated or chemically altered coins (post-mint) will weigh a normal 5.67g — weight is the definitive test. Environmental damage and dark toning can change color but not weight. A "silver-looking" coin found in change that weighs 5.67g is almost certainly plated and is worth face value only.
Market Values
- $20–$50 — Raw
- $100–$300 — Certified MS65+
Auction Record
~$300+ for a certified example. See the documented sale: GreatCollections — 2021-D Reverse Missing Clad Layer, NGC MS-64 (4.7g).
2021 Struck Through Grease
Struck through grease: a missing or weak letter where die grease filled the recess, producing 'IN GOD WE RUST.'
Origin & Background
Lubricant or debris can accumulate in the recesses of a working die. When the die strikes the planchet, the grease occupies the space that would normally impart the design — leaving a smooth, recessed void where a design element should be. The most recognizable manifestation is the "IN GOD WE RUST" effect, where grease fills the T recess in TRUST, producing a smooth blank where the letter should appear.
How to Identify
- Look for localized areas of missing or extremely weak design — letters, numerals, or portrait details that are smooth and recessed rather than raised.
- The affected area should be smooth and uniform, not scratched or damaged.
- Surrounding design elements should be sharp and normal — the weakness is strictly localized to where grease blocked the die.
- A missing "P" mintmark may indicate a struck-through-grease event ($5–$10), not a rare no-mintmark error.
False Positives to Avoid
Late Die State (LDS) coins show overall mushy detail everywhere, not isolated missing elements. Worn circulated coins lose detail from the highest points first (cheekbones, hair tips). A missing mintmark from wear looks worn, not smooth. True struck-through-grease has a clean, polished-looking smooth spot in an otherwise sharp coin.
Market Values
- $2–$5 — Minor (single weak letter)
- $5–$20 — Significant (multiple missing elements or full motto affected)
- $30–$60 — Certified MS65/MS66 with dramatic effect
2021 Washington Quarter Common Traps & False Alarms
These four traps account for the overwhelming majority of disappointed 2021 quarter sellers. Learn them before listing or buying anything.
⚠️ Trap 1: Machine Doubling — The Universal False Alarm
A second, shadow-like image beside the date "2021," "LIBERTY," or the mottos. Looks like doubling — it is not a doubled die.
The die shifts or bounces slightly as it retracts from the just-struck coin (called "mechanical bounce"), dragging across the surface and flattening the existing relief. This is a production artifact, not a die variety.
- The secondary image is flat and shelf-like — a step-down that makes letters look narrower or smaller.
- True Doubled Dies show a rounded, raised secondary image with notched or split serifs, not a flat shelf.
- Machine Doubling reduces design elements; true doubled dies enlarge or displace them.
Machine doubling (left) — flat shelves, no value. True doubled die (right) — rounded secondary image, potentially valuable.
Value: Face value only ($0.25).
⚠️ Trap 2: The 2021-W Phantom
Listings or forum posts claiming a 2021-W quarter was found in circulation. Collectors searching 2021 rolls looking for a "W" mintmark.
The 2019–2020 "Great American Coin Hunt" W-quarter program was enormously popular. Many collectors assume it continued into 2021 — it did not. The West Point Mint produced zero circulating quarters in 2021.
- Check the date. Any "W" quarter you find dated 2021 is either a misread 2020 coin, a counterfeit, or a listing error.
- Coin World confirmed: the program ended in 2020.
- Do not waste time or money searching 2021 rolls for a 2021-W.
No 2021-W exists. The W-quarter program ended after 2020.
Value: Does not exist.
⚠️ Trap 3: "Silver" Coin Found in Change
A 2021 quarter with no visible copper stripe on the edge — appears to be a solid silver coin, prompting hope it is a rare silver proof escaped into circulation.
Post-mint plating (applying a silver-colored coating to a normal clad quarter) is a common novelty treatment. It hides the copper edge stripe but does not change the coin's weight.
- Weigh the coin. A plated clad quarter still weighs 5.67g. A genuine 99.9% silver proof weighs 6.25g.
- Silver proofs also have a mirror-like field finish and frosted devices — they look nothing like a circulation strike.
- If the weight is 5.67g, it is plated — face value only.
Value: Face value only if plated ($0.25).
⚠️ Trap 4: "Mushy" Details — Late Die State, Not an Error
Soft, indistinct detail throughout the coin — Washington's hair lacks definition, letters look rounded, the boat scene is fuzzy overall. Sellers sometimes list these as "error" coins.
The intricate Crossing the Delaware design wore down working dies quickly under high-speed striking conditions. A die that has struck hundreds of thousands of coins produces progressively weaker details — this is a Late Die State (LDS) coin, not an error.
- Mushy detail is uniform across the entire design — everything is soft, not just one element.
- A genuine die chip is a raised lump in a specific spot. A genuine struck-thru is a smooth recessed spot. LDS coins show neither.
- LDS coins are generally less desirable to collectors, not more.
Value: Face value or slight discount for low-grade collectors.
2021 Washington Quarter Value: How Grade Affects What You Get
Grade — the numerical score assigned to a coin's condition — dramatically multiplies error premiums on 2021 quarters. The gap between a raw (uncertified) find and a certified high-grade specimen can be significant.
| Error Type | Raw Circulated | Raw Uncirculated | Certified MS65/66 |
|---|---|---|---|
| "Crown" Die Chip (Stage 3) | $10–$20 | $15–$35 | $25–$50 |
| "3 Oar" WDDR-003 | $5–$15 | $20–$45 | $45–$75+ |
| Missing Clad Layer | $20–$50 | $50–$100 | $100–$300 |
💡 The Grading Economics Rule
Grading fees at PCGS or NGC typically run $30–$50+ per coin for economy-tier submissions. For most 2021 Crown chips or minor feeder finger finds, grading costs exceed the coin's potential value. Only submit for certification if your raw coin is clearly worth $50+ — namely a Stage 3 Full Crown in full Mint State luster, a confirmed WDDR-003 in gem condition, or a Missing Clad Layer.
Required tools: a 10x–16x loupe to distinguish Machine Doubling from true doubled dies, a digital scale accurate to 0.01g to flag underweight planchet errors, and a magnet to screen for counterfeits (genuine quarters are non-magnetic).
2021 Washington Quarter Errors: When to Get Certified
Third-Party Grading (TPG) by PCGS or NGC does three things: it confirms the error is genuine (not PMD or post-mint alteration), assigns a grade that validates value, and makes the coin easier to sell at a fair price. For 2021 quarters, the certification threshold is straightforward.
Submit to PCGS or NGC If:
- Your coin is underweight (<5.2g) with a copper-colored face — Missing Clad Layer errors regularly sell for $100–$300 certified.
- You have a confirmed WDDR-003 "3 Oar" variety in Mint State — graded examples trade at $45–$75+, well above grading costs.
- You have a Stage 3 Full Crown die chip in gem uncirculated condition (full luster, no contact marks) — certified examples reach $50–$80.
- Any error suspected to be worth $50 or more raw.
Do NOT Submit:
- Stage 1 or Stage 2 die chips — grading cost exceeds return.
- Any coin showing Machine Doubling — it is not a variety and TPGs will note it as such.
- Minor struck-through-grease coins — the error value rarely justifies fees.
⚠️ Never Clean Your Coin
Cleaning a coin — even gently rinsing it — permanently destroys its numismatic value. Handle all potential errors by their edges only. A cleaned error coin receives a "details" designation from TPGs and is worth a fraction of an uncleaned example.
Dealer information not available. For selling verified errors, consider Heritage Auctions, GreatCollections, or established numismatic dealers at major coin shows.
2021 Washington Quarter Errors: Frequently Asked Questions
Is my 2021 quarter worth anything?
Most 2021 quarters are worth face value ($0.25) in circulated condition. Uncirculated examples fetch $1–$3. The coin becomes worth significantly more only if it carries a verified error: a Stage 3 Crown die chip ($10–$35), the WDDR-003 variety ($5–$75 depending on grade), a Missing Clad Layer ($20–$300+), or a major striking error.
Does the 2021-W quarter exist?
No. The West Point Mint's W-quarter circulating program ran exclusively in 2019 and 2020. No 2021-W quarters were struck for circulation. Any coin claimed to be a "2021-W" is either a misread 2020 coin, a counterfeit, or a listing error. Do not search 2021 rolls for it.
What is the "Crown" die chip and how do I find it?
The "Crown" is a progressive interior die break (IDB) on the Crossing the Delaware reverse — a raised lump of metal on Washington's tricorn hat. Look for a raised (not sunken) irregular mass on the hat's upper ridge. Size matters: Stage 1 buds are face value; Stage 3 Full Crown (>75% hat coverage) is worth $10–$35 raw. Found on both P and D mint coins.
How do I tell machine doubling from a real doubled die?
Machine Doubling (MD) creates a flat, shelf-like step-down beside design elements — the secondary image is flattened and the letter looks narrower. A true Doubled Die (like WDDR-003) creates a rounded, raised secondary image with notched or split serifs at letter corners. MD has zero numismatic value. Use a 10x loupe — if it looks like a flat shelf, it's MD.
What is the "3 Oar" variety (WDDR-003)?
The WDDR-003 is a Class VIII Tilted Hub doubled die on the 2021-P Crossing the Delaware reverse. It shows a distinct ghost oar shaft below the primary oar held by the boatmen — creating the visual impression of a third oar. It's the top cherrypicker variety for 2021, worth $5–$15 raw and $45–$75 certified in gem grades.
My 2021 quarter has no "P" — is that an error?
A missing or very weak P mintmark on a 2021 quarter is most likely a minor Struck Through Grease error — worth $5–$10, not a major rarity. If the surface where the P should be is smooth and recessed, grease filled the mintmark recess during striking. If the mintmark area looks worn or flat, it may simply be die deterioration or circulation wear.
Should I get my 2021 quarter graded?
Only if the raw coin is clearly worth $50 or more — mainly a Missing Clad Layer, a gem-quality WDDR-003, or a Stage 3 Full Crown in full Mint State. Economy-tier grading at PCGS or NGC costs $30–$50+, making it economically unviable for minor chips or feeder finger errors. Never clean the coin before submitting.
Which 2021 design is better for error hunting?
The Crossing the Delaware reverse is far superior for error hunting. It hosts the Crown die chip (P and D), the WDDR-003 variety (P only), feeder finger scrapes, and Missing Clad Layer errors. The Tuskegee Airmen design is primarily useful for feeder finger checks and minor die chips. The Tuskegee issue also had a lower mintage, making high-grade Mint State examples statistically scarcer in bank rolls.
