Check your coin for valuable errors and varieties
Values shown are typical retail estimates as of 2026-01 based on retrospective auction data.
Error coin values vary significantly based on grade, eye appeal, dramatic visual impact, and current market conditions.
Professional authentication (PCGS/NGC) is recommended for high-value errors and W-mint quarters targeting MS67+.
Machine Doubling (flat, shelf-like) is NOT a valuable error and is extremely common on 2020 quarters.
Die chips on 2020 quarters are very common and carry minimal premium ($2–$10). Do not confuse with major errors.
W-mint quarter values are heavily condition-dependent. Most circulated examples are worth $10–$15. Grading fees may exceed value below MS66.
The 2020 coin shortage caused distribution anomalies. Localized concentrations of certain errors may exist.
In 2020, the U.S. Mint did something it had never done before: it stamped a tiny privy mark—a V75 cartouche honoring the 75th anniversary of World War II's end—on West Point quarters, then quietly slipped just 2 million of them into ordinary bank bags. At the same time, the COVID-19 pandemic triggered a nationwide coin shortage that scrambled distribution patterns and sent coin roll hunters into overdrive. The result: a vintage packed with legitimate finds—a bat's face obliterated by machine grease, a certified doubled die variety, a copper-red "Red Quarter" sold for $2,499, and W-mint rarities with a documented ceiling of $40,000. See standard 2020 quarter base values here—this guide focuses entirely on the errors and varieties worth real money.

2020 Quarter Quick Checks: Do You Have Something Valuable?
Work through these in order. You need a 10× loupe (magnifying glass) for most checks and a digital scale for the Red Quarter check. Items marked ⚠️ are confirmed traps with no added value.
Check 1: Blind Bat Strike-Through (American Samoa P-mint only)
The mother bat's face on the reverse of the American Samoa quarter. Focus on the eye and surrounding facial features.
Partial to complete obliteration of the bat's facial features, leaving a smooth, ghost-like flat surface. Full face missing is most valuable. Partial obstruction still carries a premium.
Post-mint damage from grinding or hammering shows parallel scratch marks or displaced metal around the missing area. A genuine strike-through will have the texture of the original planchet surface—slightly rough or pebbled—with no tool marks.
Check 2: Salt River Bay Doubled Die Obverse — WDDO-001 (Salt River Bay design only)
Obverse inscriptions "IN GOD WE TRUST" and "LIBERTY," Washington's hair details, and the date on any Salt River Bay quarter (P or D).
Distinct doubling shifted to the North/Northwest on inscriptions. Split serifs on letter corners — the serif tip looks like a "W" rather than a "V." Lettering appears wider than normal. Extra thickness visible in hair details.
Machine Doubling (MD) is flat and shelf-like, making letters appear thinner or stepped like a staircase. It has zero numismatic value. True Doubled Die (DDO) doubling is rounded and raised, with split serifs and wider lettering. These are easy to confuse—use a loupe and compare carefully.
Check 3: Missing Clad Layer — the "Red Quarter" (scale required)
One entire side of the coin will appear copper-red — like a penny — instead of the normal silver-gray color. Also check the coin's edge for uneven layering.
One full side shows uniform copper color; the other side is normal. Coin weighs approximately 4.7 g instead of the standard 5.67 g. A full design strike must be visible on both sides.
Environmental toning or chemical damage can turn a coin reddish-brown but will not produce a clean, uniform copper surface. Toned coins weigh a normal 5.67 g. Always weigh the coin — weight is the fastest way to confirm or rule out this error.
Check 4: Off-Center Strike (all mints)
The entire coin. The design will be noticeably shifted with a blank, unstruck crescent visible on one side.
Design clearly shifted off center with a visible blank crescent where the dies never contacted the planchet. Higher percentage off-center (25–50%+) with the full date still visible is most desirable. W-mint off-centers are extremely rare and command a major premium.
A misaligned die strike looks slightly off but has no blank crescent — the design still covers the full planchet. A broadstrike spreads design beyond normal diameter but stays centered. Neither has significant value.
Check 5: Struck on Wrong Planchet (scale required)
The coin's overall size and edge. A quarter struck on a nickel planchet will be visibly smaller (21.2 mm vs. 24.26 mm) and parts of the design will be cut off.
Coin is noticeably wrong size or weight. A nickel planchet measures 5.00 g and 21.2 mm with a solid cupro-nickel edge (no copper core visible on the edge). The design shows clean strike quality where present, with natural truncation at the planchet rim.
A damaged, filed, or hammered quarter that appears smaller will show tool marks, uneven edges, and signs of manipulation. Genuine wrong-planchet errors have clean, natural planchet edges with no sign of post-mint alteration.
Check 6: Die Chips (minor premium)
Common spots: bat's head ("Crown" chip, American Samoa), corner of Washington's mouth ("Drooling George," any design), Weir Farm painter's smock, tree foliage, and butterfly wings on Tallgrass Prairie.
Small raised lumps caused by a piece of the die breaking away. Die chips are very common on 2020 quarters across all designs. They carry a small novelty premium only.
Post-mint contact damage. Die chips are always raised with smooth, rounded surfaces consistent with the coin's strike. PMD bumps tend to be irregular with displaced metal pushed aside.
⚠️ TRAP: Machine Doubling — Worth Face Value Only
Date and lettering on both sides of any 2020 quarter, often marketed online as a "doubled die."
Letters or numbers appear doubled with a flat, stepped, shelf-like secondary image. The lettering often appears thinner or smaller than normal. Extremely common.
The secondary image is flat — not rounded. Letters appear thinner, not wider. Serifs are not split. Caused by a loose die flexing during the strike, not a hub misalignment. Zero numismatic value.

2020 Quarter Valuable Errors & Varieties: Full Guides
The 2020 series produced six categories of coins with genuine premium value. Here is what to look for, how to confirm it, and what it's worth.
2020-W V75 Quarter — West Point Mint
2020-W quarter obverse showing the V75 privy mark location below "IN GOD WE TRUST" (left) compared to a standard P-mint obverse (right).
Origin & Background
West Point has historically produced only bullion and commemorative coins. In 2020 — continuing a program begun in 2019 — the Mint struck 2 million quarters per design at West Point and salted them into bulk bags alongside hundreds of millions of P and D coins. Finding one was statistically about one in every 250–300 quarters. What made 2020 unique was the addition of the V75 privy mark: a small cartouche shaped like the Rainbow Pool at the World War II Memorial in Washington, D.C., inscribed with "V75" to honor the 75th anniversary of Allied victory. This was the first privy mark ever placed on a circulating U.S. quarter, creating a one-year-only obverse type.
How to Identify
- Mint mark: A small "W" appears on the obverse below "IN GOD WE TRUST."
- Privy mark: A tiny V75 cartouche (shaped like the Rainbow Pool) sits adjacent to the W mint mark.
- No "W" quarter was sold directly to collectors — all entered circulation through Federal Reserve banks.
Why Grade Is Everything
Because W quarters traveled in ballistic bags colliding with millions of other coins, contact marks on Washington's cheek are almost universal. Most pulled from circulation grade between AU55 and MS64. Only coins that miraculously avoided bag damage reach MS67 — and MS68 examples are so rare that a single Marsh-Billings-Rockefeller specimen graded PCGS MS68 sold for $40,000 in December 2021. Typical MS68 range is $2,000–$5,000+. Do not clean your W quarter under any circumstances.
Market Values by Grade
- • Circulated (AU50–58): $10–$15 — not worth grading fees
- • MS65–66: $30–$90 — thin margins for grading
- • MS67: $300–$600+ — the investment tipping point
- • MS68: $2,000–$5,000+ — registry-tier rarity
Notable Auction Records
$40,000 for 2020-W Marsh-Billings-Rockefeller PCGS MS68 (December 2021 — extreme registry outlier). $1,250 for 2020-W Weir Farm MS67 (GreatCollections). $320–$621 for 2020-W American Samoa PCGS MS67 (PCGS CoinFacts).
2020-P American Samoa "Blind Bat" Strike-Through
Normal American Samoa bat face (left) vs. full Blind Bat strike-through showing smooth, featureless ghost surface (right).
Origin & Background
A strike-through error occurs when foreign material — in this case a slurry of machine lubricant and metal dust — becomes lodged in the recessed area of the die corresponding to the mother bat's face. Every coin struck by that fouled die reproduces the obstruction. Discovered early in the release cycle on Philadelphia Mint coins, early examples sold for substantial premiums. The pandemic-driven coin shortage concentrated this error on the East Coast, which explains its regional discovery pattern.
How to Identify
- The bat's facial features — especially the eye — are partially or completely missing, replaced by a smooth, flat, ghost-like surface.
- The missing area has the texture of the original planchet surface: slightly rough or pebbled. No raised metal around the edges.
- Full obliteration (entire face missing) is most valuable; even a missing eye counts as a partial obstruction.
False Positives to Avoid
Post-mint damage from grinding or hammering shows parallel scratch marks or displaced metal around the affected area. If you see any tool marks, ridges, or metal pushed up around the missing area, it is not a genuine strike-through.
Market Values
- • Minor / partial obstruction (one feature missing): $10–$30
- • Full "Blind" obliteration (entire face missing), raw: $50–$150
- • Certified MS66 with "Struck Through" attribution: $295–$500+
Auction Record
$500+ for PCGS MS66 with Struck Through attribution.
2020 Salt River Bay Doubled Die Obverse — WDDO-001 / DDO-001
Machine doubling (left, flat shelf effect) vs. true WDDO-001 (right, rounded split serifs on "IN GOD WE TRUST").
Origin & Background
Unlike the Blind Bat (a one-coin accident), the Salt River Bay DDO is a die variety — every coin struck by that specific working die carries the same doubling. Modern U.S. mints use a "single-squeeze" hubbing process where the die is pressed against the hub only once. If the die slightly tilts or shifts during this squeeze (known as Class VIII Tilted Hub Doubling), the result is a permanent doubled die that will reproduce on every coin until the die is retired. Attribution codes: WDDO-001 (Wexler) / DDO-001 (Variety Vista). See the diagnostic page: Variety Vista DDO-001.
How to Identify
- Inscriptions: Distinct doubling shifted to the North/Northwest on "IN GOD WE TRUST" and "LIBERTY."
- Serifs: The corners of letters are split or notched — the serif tip looks like a "W" rather than a clean "V." This is the single fastest diagnostic.
- Letter width: True DDO lettering appears wider than on a normal coin.
- Central design: Extra thickness and separation lines visible in Washington's hair and on the date.
False Positives to Avoid
Machine Doubling (MD) is the most common false alarm. MD produces a flat, shelf-like secondary image that makes letters appear thinner — the opposite of a true DDO. MD has zero numismatic value. Always compare the letter width and serif shape before claiming a DDO find.
Market Values
- • Raw, found in circulation: $20–$50
- • Certified MS65/MS66: $150–$400
Auction Record
$400 for certified MS66.
2020 Quarter Missing Clad Layer — The "Red Quarter"
2020-D American Samoa quarter with reverse clad layer missing, showing the full copper-red surface on one side.
Origin & Background
Quarters are made from a clad strip: a pure copper core bonded to outer layers of 75% copper / 25% nickel. Occasionally, a section of this strip delaminates (peels apart) before it reaches the blanking press. If a planchet is punched from a section where the outer layer is missing, the resulting coin has one copper-red side and one normal silver side. A 2020-D American Samoa quarter was authenticated with 98% of the reverse clad layer missing — its reverse is fully copper-red while the obverse is normal.
How to Identify
- One entire side of the coin is uniform copper-red — clean, not splotchy or mottled.
- Weigh the coin on a digital scale: a missing clad layer quarter weighs approximately 4.7 g vs. the standard 5.67 g.
- The edge will show evidence of the missing cladding layer — uneven appearance where layers are absent.
- Both sides must show a full, normal design strike.
False Positives to Avoid
Environmental toning or chemical damage can create reddish-brown discoloration — but it will not produce a clean, uniform copper surface across an entire side. Toned coins weigh a normal 5.67 g. Weight is your fastest diagnostic tool.
Auction Record
$2,499 for the 2020-D American Samoa quarter with 98% reverse clad missing, graded MS64.
2020 Quarter Struck on Wrong Planchet
Quarter design struck on a nickel-sized planchet (21.2 mm, left) vs. normal quarter (24.26 mm, right), showing design truncation at the smaller planchet edge.
Origin & Background
The Mint feeds pre-cut planchets (blank coin discs) automatically into the coining press. Occasionally, a planchet intended for a different denomination — such as a Jefferson Nickel — is fed into the quarter coining press. The quarter dies stamp the full quarter design onto the wrong-size planchet, cutting off part of the design at the planchet edge.
How to Identify
- Coin is visibly smaller than a normal quarter (24.26 mm). A nickel planchet measures 21.2 mm.
- Parts of the quarter design are naturally cut off where the design runs beyond the planchet edge.
- The edge is solid cupro-nickel with no copper core visible (on a nickel planchet).
- Weight: a nickel planchet is 5.00 g — different from both a quarter (5.67 g) and from a missing-clad quarter (~4.7 g).
False Positives to Avoid
A filed or hammered quarter that has been artificially reduced in size will show tool marks and uneven, irregular edges. Genuine wrong-planchet errors have clean, natural planchet edges — the design simply stops where the planchet ends, with no sign of post-mint alteration.
Market Values
Typically $500–$1,500+ depending on the hosting planchet type, visual drama of the error, and grade. No specific 2020-dated wrong-planchet auction record is documented in current data.
2020 Quarter Off-Center Strike
Off-center quarter showing blank crescent at bottom right and full date visible — the ideal combination for maximum value.
Origin & Background
An off-center strike occurs when the planchet is not properly centered in the collar when the dies strike. The design lands partially off the coin's edge, leaving a blank, unstruck crescent. The percentage off-center determines value — a 50% off-center example is worth far more than a 10% example. The holy grail combination is a high-percentage off-center with the full date still visible.
The W-Mint Off-Center Premium
Finding a 2020-W quarter — already one in ~250–300 quarters — that also has a major striking error is statistically extraordinary. A PCGS MS66 2020-W Salt River Bay quarter with a 16% off-center strike sold for $560 in 2023. Standard P/D off-centers at 10–50% trade for $20–$100 depending on the percentage and grade.
Auction Record
$560 for 2020-W Salt River Bay, 16% off-center, PCGS MS66 (2023).
2020 Quarter Common Traps: What Looks Valuable But Isn't
These are the most frequently misidentified "errors" on 2020 quarters. Knowing them saves you from overpaying — or from embarrassing yourself at a coin show.
⚠️ Machine Doubling (MD) — The #1 False Alarm
Letters or numbers on the date, "IN GOD WE TRUST," or reverse inscriptions appear doubled. The secondary image runs parallel to the primary letter.
A loose die chatters or flexes slightly during the strike, dragging the design sideways. This is a mechanical issue with the press, not a master hub issue. It is extremely common on modern coins.
- The secondary image is flat and shelf-like, not rounded and raised.
- Letters appear thinner — machine doubling removes detail, it does not add width.
- Serifs are NOT split. On a true DDO, the serif looks like a "W"; on MD it looks sheared or stepped like a staircase.
- Seen on every denomination, every year. Not a rarity.
Value: Face value only.
⚠️ Die Chips — Common, Low-Value Novelties
Small raised bumps or lumps on the design — a "crown" on the bat's head, a blob at Washington's mouth (marketed as "Drooling George"), or bumps on butterfly wings.
Pieces of the working die break away from stress. The resulting void in the die produces a raised blob on every coin struck afterward. Very common on 2020 quarters due to intricate reverse designs.
- The bump is raised and smooth — consistent with the coin's normal strike surface.
- Found on many coins from the same die — not unique to your coin.
- No missing design detail, distorted lettering, or planchet issues accompany a simple die chip.
Value: $2–$10 novelty premium only. Not worth professional grading fees.
⚠️ Environmental Toning Mistaken for Missing Clad
One or both sides of the coin appear brownish-red or coppery, causing excitement that it's a "Red Quarter."
Coins exposed to certain chemicals, PVC plastic holders, or acidic environments can develop reddish or brown toning that darkens the copper in the clad alloy's surface.
- Weigh the coin. A genuine missing-clad error weighs ~4.7 g. A toned coin weighs a normal 5.67 g.
- Toning is mottled and uneven; a true missing clad layer is a clean, uniform copper surface.
- Chemical damage often shows pitting, spots, or surface roughness absent on a genuine error.
Value: Face value only. A scale is your fastest diagnostic.
2020 Quarter Grading: Why Grade Matters So Much
For most modern coins, the difference between MS64 and MS67 is a few dollars. For 2020-W quarters, it can be the difference between $30 and $500. This is because the "salting" distribution method — tossing W quarters into bags with millions of other coins — creates severe contact marks. Pristine surfaces are genuinely rare.
MS64 W quarter with visible bag marks on Washington's cheek (left) vs. MS67 example with clean, unmarked fields (right) — the difference is worth hundreds of dollars.
Key Grading Thresholds
- AU55–58 (Circulated): Visible wear on high points. Worth $10–$15. Grading fees exceed value — sell raw.
- MS63–64: No wear but significant bag marks. Worth $15–$30. Grading cost likely exceeds return.
- MS65–66 (Gem): Clean coin, minimal marks. Worth $30–$90. Thin margins; only submit with bulk deals.
- MS67 (Superb Gem): Nearly mark-free fields, especially Washington's cheek. Worth $300–$600+. The investment tipping point — worth grading fees if the coin looks pristine under a loupe.
- MS68 (Registry): Essentially lottery-ticket territory. Effectively mark-free. Worth $2,000–$5,000+, with outlier sales as high as $40,000.
For the Blind Bat error: only grade if the obstruction is dramatic (full face missing). Minor grease strikes sell better raw.
2020 Quarter Authentication: When to Get Certified
PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Company) are the two leading third-party grading (TPG) services. Certified coins sell for significantly more than raw (uncertified) examples for high-value errors because buyers can trust the grade and attribution.
Submit for Grading If:
- Your 2020-W quarter appears pristine under a 10× loupe with minimal marks on Washington's cheek — it may be MS67+.
- You have a confirmed Blind Bat with full obliteration of the bat's face (not a minor partial).
- You have an authenticated missing clad layer (confirmed by weight at ~4.7 g).
- You have a confirmed wrong-planchet error with correct measurements.
- You have a significant off-center strike (15%+), especially on a W-mint coin.
Do NOT Submit If:
- Your W quarter shows visible scratches, rim dings, or dull luster — sell it raw as a circulated example.
- You have a machine-doubled coin — it has no certification value.
- You have minor die chips — grading fees will exceed the value premium.
- You have an S-mint silver proof that remains in its original capsule — the capsule itself preserves value better than cracking it out for submission.
⚠️ Never Clean Your Coin
Cleaning a coin — including wiping it with a cloth — destroys the original surface and makes it ungradeable. A "cleaned" designation from a TPG can reduce a coin's value to below face value. Handle all potential error coins by their edges only.

2020 Quarter Errors: Frequently Asked Questions
How do I identify a 2020-W quarter?
Look on the obverse (heads side) for a small "W" mint mark below "IN GOD WE TRUST." Next to it is the V75 privy mark — a tiny cartouche shaped like the Rainbow Pool. No W-mint quarter was sold directly to collectors; all entered circulation through Federal Reserve banks. The V75 privy mark appears on all five 2020-W designs and no other U.S. circulating quarter.
My 2020 quarter has doubling on the lettering. Is it valuable?
Probably not — unless it's the Salt River Bay design. The overwhelming majority of doubled lettering on 2020 quarters is Machine Doubling, which has zero numismatic value. Machine doubling is flat and shelf-like, making letters appear thinner. The valuable WDDO-001 only exists on the Salt River Bay quarter, shows rounded raised doubling with wider letters, and has clearly split serifs (the letter corners look like "W" shapes). If your coin is Weir Farm, American Samoa, Marsh-Billings, or Tallgrass Prairie, doubling is almost certainly machine doubling.
What is the V75 privy mark and why does it matter?
The V75 privy mark is a small cartouche shaped like the Rainbow Pool at the World War II Memorial in Washington, D.C., inscribed with "V75" to commemorate the 75th anniversary of Allied victory in World War II. It appears on all 2020-W quarters and was the first privy mark ever used on a circulating U.S. quarter. This makes all 2020-W quarters a one-year-only obverse type — meaning the design was never repeated — which supports their collector premium beyond just mintage rarity.
How do I tell a missing clad layer from ordinary toning?
Weigh it. A genuine missing-clad-layer quarter weighs approximately 4.7 g instead of the standard 5.67 g — a clearly measurable difference on any decent digital scale (accurate to 0.01 g). Toned or chemically damaged coins weigh normal. A genuine error also shows a clean, uniform copper surface — not mottled, pitted, or spotted. If the reddish area looks uneven or has surface texture inconsistencies, it is likely damage or toning, not a mint error.
Should I get my 2020-W quarter professionally graded?
Only if it has a realistic shot at MS67 or higher. Grading fees (typically $30+ per coin at standard service levels) exceed the added value for circulated or MS63–66 examples. Inspect your coin carefully under a 10× loupe: if Washington's cheek is clean, the fields are bright, and you see no bag marks, it may be MS67+ and worth submitting. If you see any significant marks or dull luster, sell it raw as a circulated W quarter ($10–$15).
What is the most valuable 2020 quarter error?
By documented auction record, a 2020-W Marsh-Billings-Rockefeller quarter graded PCGS MS68 sold for $40,000 in December 2021. This is an extreme outlier driven by registry set competition among wealthy collectors. More typical top-end values: Missing Clad Layer ($2,499), Blind Bat certified MS66 ($500+), Salt River Bay DDO certified MS66 ($400). The $40,000 sale represents the rarest condition (MS68) of already-rare W-mint coins.
Are 2020 silver proof quarters valuable?
Moderately. The 2020-S silver proof quarters are struck in .999 fine silver (6.343 g per coin) and were sold as part of collector sets, not distributed in circulation. With mintages around 427,000 per design, they are not rare, but they do carry a collector premium. PR70 DCAM (perfect proof, deeply cameo) examples typically sell for $30–$50. Standard PR69 DCAM examples trade for less. Keep them in their original capsules — .999 silver is softer than older 90% silver and scratches very easily.
Why were 2020 W quarters hard to find?
Two reasons. First, only 2 million W quarters were minted per design — less than 1% of combined P/D production. Second, they were not sold directly to collectors but "salted" randomly into bulk bags of P and D coins before shipment to Federal Reserve banks. The COVID-19 pandemic worsened distribution: Federal Reserve allocation limits slowed coin movement, and some W quarters reportedly remained sequestered in vaults, delaying their entry into circulation and sustaining price volatility through 2021–2022.

A note on images: To help illustrate coin diagnostics and rare varieties — especially complex errors that are difficult to describe in text alone — this guide uses AI-generated images. All written values, diagnostics, and variety attributions have been manually reviewed against the cited sources above. While our editorial team works to ensure every image is accurate and helpful, AI-generated illustrations may occasionally misrepresent fine details. If you spot any discrepancy between an image and its written description, please contact us or leave a comment below — we review all feedback and correct errors promptly. Numismatic knowledge is a community effort, and your input helps us build a more accurate resource for everyone.
