2017 Washington Quarter Errors: Value Guide & Rare Varieties
Is your 2017 Washington quarter worth more than 25 cents? Complete error guide covering the Frederick Douglass DDR (FS-801), Ozark Snow on Roof die chip, missing clad layer, and more. Values updated January 2026.
Most 2017 Washington quarters are worth face value, but the Frederick Douglass DDR (FS-801) has sold for $576 at Heritage Auctions — and three other errors are worth real money if you know exactly where to look.
- 🏛️ Frederick Douglass DDR (FS-801): Raised extra bars inside the house windows — $20–$150+ raw, $576 at MS68
- 🌊 Ozark "Snow on Roof" die chip: Raised metal blob on the mill roofline — $2–$10
- 🟤 Missing clad layer: Copper-red face + underweight coin — $35–$125+
- ⭐ S-Mint Business Strike (NIFC): Matte-finish S-mint not released for circulation — $2–$6 uncirculated
⚠️ The "Ring of Death" circular groove and flat machine doubling on the date are the two most common traps — both are worth exactly $0.25.
2017 Washington Quarter Errors Error Checker
Check your coin for valuable errors and varieties
Values shown are typical retail estimates as of 2026-01.
The 2017 ATB series includes five reverse designs (Effigy Mounds, Frederick Douglass, Ozark Riverways, Ellis Island, George Rogers Clark). Error premiums vary by design.
Error coin values vary based on grade, eye appeal, and market conditions.
Professional authentication (PCGS/NGC) is recommended for high-value varieties, especially the Frederick Douglass DDR (FS-801).
Machine Doubling (flat, shelf-like) is NOT a valuable error — it is extremely common on 2017 quarters.
The Ring of Death (circular scoring from coin rolling machines) is post-mint damage and has no numismatic value.
Plating blisters on clad coins are common manufacturing defects, not valuable errors.
S-mint quarters found in circulation are not wrong mint mark errors — San Francisco struck millions of quarters for collectors in 2017.
The 2017 America the Beautiful quarter program released five distinct reverse designs — Frederick Douglass, Ozark Riverways, Ellis Island, Effigy Mounds, and George Rogers Clark — across three mints, with Philadelphia and Denver each striking over 180 million coins per design. That volume means genuine errors exist, but so does an enormous amount of damage and machine wear that mimics them. This guide gives you a precise checklist for your 2017 Washington quarter: what to keep, what to submit, and what to spend without a second thought. Values as of January 2026.

2017 Washington Quarter Specifications and Mintage
Lock in the standard specs before hunting errors. Any physical deviation from these numbers is your first clue to investigate further.
| Specification | Standard Value |
|---|---|
| Composition | Copper-nickel clad — 75% Cu / 25% Ni outer layers over a pure copper core |
| Weight | 5.67g (tolerance ±0.23g; flag anything below 5.4g or above 5.9g for P/D coins) |
| Diameter | 24.26 mm |
| Edge | Reeded; copper stripe always visible mid-edge on a standard clad coin |
| Magnetic? | No — the Cu-Ni alloy is non-magnetic; a coin that sticks to a magnet is a counterfeit or novelty |
| Silver Proof weight | 6.25g (90% silver; S-mint Proof sets only) |
2017 Mintage at a Glance
| Mint | Type | Approx. Mintage | Baseline Value |
|---|---|---|---|
| Philadelphia (P) | Business Strike | 184M–271M per design | $0.25–$1.50 |
| Denver (D) | Business Strike | 185M–254M per design | $0.25–$1.50 |
| San Francisco (S) | Business Strike (NIFC) | ~900,000–975,000 | $2.00–$6.00 |
| San Francisco (S) | Clad Proof | ~657,000–692,000 | $4.00–$6.00 |
| San Francisco (S) | Silver Proof (90% Ag) | ~496,000 | $10.00–$20.00 |
| San Francisco (S) | Enhanced Uncirculated | 225,000 | $5.00–$15.00 |
ℹ️ S-Mint Business Strike: Not a Mint Error
Since 2012 the San Francisco Mint has struck quarters for direct collector sale — not for public circulation. These "S-Mint Business Strikes" (NIFC: Not Intended For Circulation) look identical to P/D coins at a glance: same matte finish, same weight (5.67g), same composition. The only tell is the small "S" mint mark. Because only ~900,000 were struck per design versus over 180 million at each of the other mints, finding one in change is unusual and worth keeping. It is not a wrong-mint-mark error — the San Francisco Mint intentionally produced them.
Three 2017-S quarter types: Proof (mirror fields, frosted devices), Business Strike (matte finish like P/D), Enhanced Uncirculated (mixed laser-frosted and unpolished areas).

2017 Washington Quarter Quick Checks: Valuable Errors vs. Common Fakes
Run through these three checks first. If your coin passes Check 1 or 2, keep reading. If it only matches Check 3, you likely have face value.
Check 1: Frederick Douglass "Double Windows" DDR (FS-801)
The reverse (tails) of a 2017-P Frederick Douglass quarter only. Focus on the two windows immediately to the right of Douglass's seated figure on the Cedar Hill house. Secondarily check the shutters and desk area. Use a 10x–20x loupe (a magnifying glass used by coin collectors).
Clear, raised, split separation of the window panes — extra vertical bars inside the window frames. The doubling must be rounded and raised like the rest of the design, appearing as a true secondary overlapping image. This is called Class VIII (Tilted Hub) doubling and is listed in the Cherrypickers' Guide as FS-801.
Flat, shelf-like doubling on the roofline, house edge, or lettering is Machine Doubling (MD) — a common die bounce that subtracts from the design rather than adding to it. MD looks smeared and creates a step-down effect. It is present on nearly every high-volume 2017 quarter and is worth exactly $0.25.
Check 2: Ozark Riverways "Snow on Roof" Die Chip (Interior Die Break)
The reverse (tails) of any 2017-P or 2017-D Ozark National Scenic Riverways quarter. Focus on the shingled roof of the Alley Spring Mill, particularly the lower-left edge of the roofline. A 10x loupe is helpful.
A raised, irregular blob of metal on the shingles — it looks like a bird's nest or pile of snow sitting on the roof. This is an Interior Die Break (IDB): the die steel crumbled under striking pressure, leaving a void that planchet metal filled. Larger blobs command higher premiums.
Scratches, dents, or flattened areas on the roof are post-mint damage (PMD) — worth nothing extra. The error must be raised above the surface. This is also not a Doubled Die; it is purely a die degradation error where the die steel physically crumbled.
Check 3: False Alarm Filter — PMD and Machine Doubling
Both sides — especially the date "2017," "IN GOD WE TRUST," the rim, and the open fields of the Ellis Island or George Rogers Clark designs.
Ring of Death: a perfect circular groove across the coin face, caused by coin-rolling machines. Machine Doubling: flat, shelf-like doubling on the date or lettering. Plating Blisters: tiny surface bubbles from gas trapped in the clad bonding process. All three are extremely common on 2017 quarters.
- If doubling makes the date or letters look thinner with a step-down shelf, it is Machine Doubling — worth $0.25.
- If you see a perfect circular groove through the design, it is Rolling Machine damage — worth $0.25.
- If bubbles on the surface can be felt as slight indentations under a loupe, they are plating blisters — worth $0.25.

2017-S Special Issues: Proof and Enhanced Uncirculated Values
| Coin Type | Key Identifier | Weight | Undamaged Value | If Circulated (Impaired) |
|---|---|---|---|---|
| Clad Proof (S) | Mirror fields, frosted devices, copper stripe on edge | 5.67g | $4–$6 | $2–$4 |
| Silver Proof (S) | Mirror fields + solid silver edge (no copper stripe) | 6.25g | $10–$20 | $8–$12 |
| Enhanced Uncirculated (S) | Laser-frosted devices + unpolished fields (225k mintage) | 5.67g | $5–$15 | $3–$8 |
| Business Strike NIFC (S) | Matte finish identical to P/D, S mint mark | 5.67g | $2–$6 | $0.25–$1.00 |
Silver Proof quick test: Look at the edge. A standard clad quarter always shows a copper stripe. If you see solid silver on the edge and the coin weighs 6.25g on a digital scale, it is a genuine Silver Proof. If it weighs 5.67g but looks silver, it has been plated after minting — worth $0.25.

2017 Washington Quarter Rare Varieties and Errors Worth Money
Frederick Douglass DDR — FS-801 / WDDR-006
Normal window panes (left) vs. FS-801 DDR showing distinct extra vertical bars inside the window frames (right).
Origin and Background
This is the definitive cherrypick of the 2017 series and the only quarter variety with a significant, documented auction trail above $500. It results from Class VIII (Tilted Hub) doubling — a byproduct of the modern "single-squeeze" hubbing process the U.S. Mint adopted in the late 1990s. During hubbing of the working die, the hub (the master tool with the positive image) was slightly tilted. As it seated into the die steel, it left a secondary impression. Because the misalignment was central rather than rotational, the doubling concentrates on the center of the design — the house windows — rather than the peripheral lettering where machine doubling is most common. It is listed in the Cherrypickers' Guide (FS-801) and is recognized by both PCGS and NGC for certified attribution.
How to Identify
- Examine the two windows directly to the right of Douglass's head on the Cedar Hill mansion.
- Genuine FS-801 shows distinct extra vertical bars within the window panes — a true split, not a smear.
- The doubling is raised and rounded, matching the surface relief of the primary design elements.
- Secondary doubling may also appear on the shutters and the desk area.
- The outer legends (QUARTER DOLLAR, E PLURIBUS UNUM) will not show meaningful split doubling — only the central design is affected.
False Positives to Avoid
Machine Doubling (MD) is pervasive on this design. If the doubling on the house edge or lettering looks flat and creates a "step-down" shelf — as if the design was slid sideways with the step shrinking the letter — it is MD and worth $0.25. A genuine DDR makes letters or design elements wider or shows a clear notch at the corners. Use the "E" in QUARTER as a quick test: MD makes it narrower; DDR adds to it.
Market Values
- 💰 Circulated (Good–Fine): $20–$40
- 💰 Uncirculated raw (MS60–MS64): $50–$100
- 💰 Certified MS65+: $100–$150+
- 💰 Certified MS67–MS68: $200–$576+
Auction Record
$576 for MS68 (PCGS CoinFacts — Heritage Auctions, 2018). Circulated examples typically sell for $20–$40 when correctly attributed.
Ozark Riverways "Snow on Roof" — Interior Die Break
Raised metal blob on the Alley Spring Mill shingled roof — the "Snow on Roof" interior die break.
Origin and Background
The intricate shingle detail on the Alley Spring Mill roof created a structural stress point on the working dies. Under the ~40–60 tons of striking pressure, the die steel in that area fatigued and crumbled, leaving a void in the die face. On every subsequent coin struck with that die, planchet metal flowed into the void and created a raised irregular blob on the finished coin. The nickname "Snow on Roof" stuck in collector forums due to its visual resemblance to a snowdrift on the shingles.
How to Identify
- Look at the shingled roof of the Alley Spring Mill, particularly the lower-left portion of the roofline.
- The error is a raised, amorphous blob — it will catch light differently than the surrounding shingles.
- It can range from a tiny speck to a mass covering a significant portion of the roof. Larger = more valuable.
- A 10x loupe is sufficient; many examples are visible to the naked eye.
False Positives to Avoid
Scratches, dents, or worn-down areas on the roof are post-mint damage. The blob must be raised, not recessed or flat. This variety is genuinely common — bank roll hunters report finding multiple examples per box. Despite enthusiastic online listings calling it "rare," verified sold prices for circulated examples are consistently in the $2–$8 range. It is an excellent first find for a new collector but rarely justifies the cost of third-party grading ($30–$50+).
Market Values
- 💰 Small chip: $2–$5
- 💰 Medium chip: $5–$8
- 💰 Large chip covering significant roof area: $8–$10+
Auction Record
$7.19 — eBay verified sold listing, 2025 (average circulated example).
2017 Quarter Missing Clad Layer
Missing clad layer: copper-red face on reverse (left) vs. normal silver-colored nickel-clad face (right).
Origin and Background
Quarters are struck on pre-made planchets — coin blanks with a copper-nickel outer layer bonded over a pure copper core. Occasionally, a planchet enters the press with one or both outer clad layers missing. The finished coin then shows the pure copper core on the affected side, appearing distinctly copper-red. This is a pre-strike planchet error, not something that happens during or after striking.
How to Identify
- The affected side is copper-red with a smooth, non-layered appearance.
- The weight test is critical: A genuine one-side missing clad layer coin weighs approximately 4.7g–5.1g — noticeably lighter than the standard 5.67g.
- Weigh with a digital scale accurate to 0.01g. If the scale reads within the normal 5.4g–5.9g range, the copper appearance is not a missing clad layer.
- Both sides missing is extremely rare and results in a noticeably thin, lightweight coin.
False Positives to Avoid
Environmental damage — prolonged exposure to heat, chemicals, or acidic materials (like a car cup holder) — can strip the nickel layer and expose the copper core on a normal-weight coin. A 5.67g coin that appears copper has been damaged post-mint and is worth face value. Always weigh first. A digital scale is the single most important tool for this error type.
Weight test: normal quarter at 5.67g (top) vs. potential missing clad layer coin under 5.2g (bottom).
Market Values
- 💰 Partial clad missing: $10–$40
- 💰 Full one-side missing: $35–$125+
- 💰 Both sides missing: $150+
Auction Record
Similar coins have sold for approximately $50+ at auction. No specific 2017 record in the research data; professional authentication by PCGS or NGC is strongly recommended before selling.
2017 Quarter on Silver Wrong Planchet
How to Identify
- The coin has a P or D mint mark (Philadelphia or Denver).
- The edge shows no copper stripe — it is solid silver in color all the way around.
- The coin weighs approximately 6.25g on a precise digital scale.
- All three conditions must be present simultaneously to warrant investigation.
False Positives to Avoid
Plated coins are by far the most common explanation for a silver-looking P/D quarter with no copper stripe. If the coin weighs 5.67g, it has been plated after minting — worth exactly $0.25. Do not confuse with S-mint Silver Proofs, which are supposed to weigh 6.25g. A P/D coin weighing 6.25g with a solid silver edge is statistically extraordinary and requires immediate professional authentication by PCGS or NGC before any sale.
Decision Path
- P/D coin + silver-looking + 5.67g weight → Plated post-mint (PMD). Value: $0.25.
- S coin + silver-looking + 6.25g weight → Normal Silver Proof. Value: $10–$20.
- P/D coin + no copper stripe on edge + 6.25g weight → Extremely rare; submit to PCGS or NGC immediately.
2017-P Ellis Island Errors — WDDO-001 and Die Chips
Die chips appear as small raised bumps on the noses, eyes, and hands of immigrant figures on the Ellis Island design.
What to Look For
The Ellis Island design features intricate facial detail on the immigrant family figures. These high-relief areas proved to be stress points for working dies. Two types of errors result:
- WDDO-001 (Minor Doubled Die Obverse): Subtle doubling on obverse design details. Must be raised and show distinct separation — not flat MD. Requires careful comparison under magnification to a normal example.
- Die Chips ("Warts" / "Moles"): Raised bumps on the noses, eyes, lips, or hands of the immigrant figures. A die chip where the die steel crumbled and planchet metal filled the void. Also called "Extra Tears" when near the eyes.
False Positives to Avoid
Machine Doubling is extremely common on the Ellis Island obverse and must not be confused with a true DDO. Also critically: the Ellis Island design's large flat fields make it the most common target for the "Ring of Death" circular groove from coin-rolling machines. Any perfect circle cutting through the immigrant family or open field is always post-mint damage worth $0.25.
Market Context
These are specialty-collector items. The die chip market for this design is thin and largely driven by asking prices rather than verified sale prices. Most circulated examples sell in the $2–$10 range to variety specialists; the WDDO-001 DDO can reach $20 if clearly attributable. Neither variety justifies third-party grading costs on a circulated coin.
2017-S Enhanced Uncirculated — 225th Anniversary Set
To celebrate the U.S. Mint's 225th Anniversary in 2017, a special "Enhanced Uncirculated Coin Set" (Product Code 17XC) was released with a strict mintage limit of 225,000 sets. All five 2017 quarters in the set were struck at San Francisco with a proprietary finish combining laser-frosted devices and unpolished fields — distinct from both the mirror-field Proof finish and the uniform satin luster of standard business strikes.
How to Identify
- S mint mark only.
- Fields are not mirror-like (not a Proof) but not uniformly matte either.
- Devices (the raised designs) have a distinctive laser-frosted texture that catches light differently than standard Uncirculated coins.
- Weight: 5.67g — chemically identical to a standard clad quarter despite the unusual finish.
⚠️ Don't Misidentify as a Mint Error
When these sets were broken up and coins spent, some collectors mistakenly flagged the unusual finish as a "struck through" error or "wrong planchet." The coin is metallurgically standard (5.67g, non-magnetic, copper stripe on edge) — only the surface treatment is special. Verify using the U.S. Mint press release for the 225th Anniversary Enhanced Uncirculated Coin Set.
2017 Washington Quarter Error Traps: What Looks Valuable but Isn't
These are the three patterns that generate the most excitement in online forums and the most disappointment at the coin shop. Learn to recognize them quickly and save yourself the trip.
⚠️ The Ring of Death
A perfect, smooth, concentric circle scored into the coin's face, often passing through the central design — most visible on the Ellis Island quarter's large open fields. The line is clean and machine-precise.
Coin-wrapping and coin-rolling machines use a rotating collar with a protruding edge to grip the coin during the wrapping process. If the coin shifts even slightly, the collar scribes a perfect circle across the face. This happens entirely outside the Mint.
- The groove is recessed (cut into the coin), not raised — genuine mint errors from a die void are always raised.
- The circle is geometrically perfect — the Mint does not create circular design elements on quarter obverses.
- The scoring cuts through both the design and the field indiscriminately.
Value: Face value only ($0.25).
⚠️ Machine Doubling on the Date or "IN GOD WE TRUST"
The date "2017" or letters in "IN GOD WE TRUST" appear doubled or blurry — as if the numbers were slightly shifted left or right, with the ghost image slightly lower and to the side. Also common on George Rogers Clark and Frederick Douglass designs.
Machine Doubling (MD) occurs when the die bounces or vibrates loosely during or after the striking moment. The die face drags across the newly struck planchet, shaving a thin shelf of metal off the design's edge. It is a mechanical die issue, not a hubbing variety.
- Look at the "7" in 2017: if the ghost image makes the numeral look thinner or narrower with a step-down shelf, it is MD.
- A genuine Doubled Die (DDR/DDO) shows a secondary image that adds to the design — split serifs, a notch at letter corners, or an extra bar — making the element wider.
- MD is present on a large percentage of high-volume 2017 quarters. It is the norm, not the exception.
Value: Face value only ($0.25).
Machine Doubling (left): flat step-down makes letters narrower. Hub Doubling DDR (right): raised secondary image adds to the design with split serifs.
⚠️ Plating Blisters and "Bubble" Surfaces
Small bubbles or raised bumps on the coin's surface, often in the fields. They may look like tiny volcanoes or blisters scattered across the face.
Gas pockets occasionally form between the copper core and the nickel-copper outer layer during the clad bonding process. These are a known manufacturing variance in clad coinage, not a collectible error.
- True die chips (like Snow on Roof) are solid, raised metal in a specific design location.
- Plating blisters are scattered randomly across open field areas and may feel slightly soft or hollow under probe.
- They add no numismatic premium regardless of size or quantity.
Value: Face value only ($0.25).

2017 Washington Quarter Errors: How Grade Affects Value
For the 2017 series, grade matters most for the Frederick Douglass DDR (FS-801), where the difference between a circulated example and a certified MS68 is literally the difference between $25 and $576. The "MS" scale (Mint State) runs from MS60 (no wear but heavily marked) to MS70 (perfect, no flaws visible at 5x magnification).
- Circulated (G–AU): Any visible wear reduces the FS-801 DDR to the $20–$40 range. Circulated Ozark die chips remain in the $2–$8 range regardless of grade.
- MS60–MS64: Full luster but with noticeable contact marks from bag handling. The FS-801 in this range sells for $50–$100.
- MS65–MS67: Gem quality with minimal marks. FS-801 reaches $100–$200+. S-mint Business Strikes in this range become candidates for grading if the coin is exceptional.
- MS68+: Registry-quality. The FS-801 auction record of $576 was set at this level. Extremely few coins reach this tier.
For die chips, grading costs ($30–$50+ per coin) almost always exceed realized value for circulated examples. Submit die chips only if the coin is sharply struck, full luster, and the chip is unusually large.
2017 Washington Quarter Errors: When and How to Get Authenticated
Required Tools for Home Screening
- 10x–20x Triplet Loupe: Essential for distinguishing raised, split Doubled Die detail from flat Machine Doubling. A basic jeweler's loupe costs $10–$20 and is the most important coin tool you can own.
- Digital Scale (0.01g accuracy): Mandatory for the missing clad layer and wrong planchet checks. A suitable scale costs under $15 online.
- Magnet: A standard clad quarter is non-magnetic. A coin that sticks to a magnet is a steel counterfeit or novelty item, not a U.S. quarter.
When to Submit to PCGS or NGC
✅ Submit (Green Light)
- Frederick Douglass DDR (FS-801) with clear split window bars — especially if uncirculated.
- Coin weight below 5.2g with copper-red face (potential missing clad layer).
- P/D coin with no copper edge stripe and weight ~6.25g (potential silver wrong planchet — submit immediately).
- S-Mint Business Strike or Enhanced Uncirculated coin in apparent MS65+ condition found in circulation.
⛔ Don't Submit (Red Light)
- Flat, shelf-like Machine Doubling on the date or lettering — not attributable, not valuable.
- Ring of Death circular groove — always post-mint damage.
- Minor Ozark Snow on Roof die chip on a circulated coin — grading costs exceed realized value.
- Any coin with surface bubbles that can be felt as soft spots under magnification (plating blisters).
- Ellis Island die chips on circulated coins — market too thin to recover grading costs.
Both PCGS (PCGS CoinFacts — 2017-P Frederick Douglass) and NGC recognize the FS-801 variety for certified attribution. Attribution significantly increases marketability and realized price for this specific variety.
For professional numismatic dealer referrals, contact the American Numismatic Association (ANA) or the Professional Numismatists Guild (PNG). Both organizations maintain searchable member directories.
2017 Washington Quarter Errors: Frequently Asked Questions
Is a 2017 quarter with doubling on the date worth anything?
Almost certainly not. The vast majority of 2017 quarters show Machine Doubling (MD) on the date and "IN GOD WE TRUST" — a flat, shelf-like effect caused by die vibration. MD makes the numerals appear thinner with a step-down. If the doubling shows distinct, rounded separation or split serifs that make the numerals wider, it could be a genuine Doubled Die worth investigating further. But if it looks smeared or flat, it is MD worth $0.25.
I found a 2017-S quarter in my change. Is it valuable?
Possibly, yes. Look at the finish. If it has mirror-like fields and frosted devices, it is a Proof that was broken out of a collector set — worth $4–$6 for a clad Proof or $10–$20 for a Silver Proof (which weighs 6.25g and has no copper stripe on the edge). If it has a matte finish identical to a P/D coin, it is an S-Mint Business Strike (NIFC) worth $2–$6 uncirculated. It is not a wrong-mint-mark error — the San Francisco Mint intentionally struck these for collectors.
What is the most valuable 2017 quarter error?
The 2017-P Frederick Douglass DDR (FS-801 / WDDR-006) is the most valuable confirmed variety, with a verified auction record of $576 for an MS68 example at Heritage Auctions in 2018. Circulated examples with clear window-pane doubling typically sell for $20–$40. A wrong-planchet error on a silver planchet would theoretically exceed this, but no confirmed example has been documented for this year.
My 2017 quarter appears to be copper or reddish. Is it valuable?
Weigh it immediately on a digital scale. A coin weighing 4.7g–5.1g may be missing one clad layer (worth $35–$125+). A coin weighing 5.67g has been damaged by environment, heat, or chemicals post-mint — it is worth face value. Environmental damage that strips the nickel layer is extremely common and is the explanation in the vast majority of copper-colored quarter finds.
What is the "Snow on Roof" error and is it actually rare?
The "Snow on Roof" is an Interior Die Break (IDB) on the 2017 Ozark National Scenic Riverways quarter — a raised metal blob on the shingled roof of the Alley Spring Mill caused by the die steel crumbling under striking pressure. It is genuinely a mint error, but it is not rare. Bank roll searchers routinely find multiple examples per box. Despite enthusiastic online listings, verified sold prices for circulated examples are typically $2–$8. A great first find for a new collector, but the grading cost usually exceeds the coin's market value.
What is the Ring of Death and should I keep the coin?
The Ring of Death is a perfect circular groove scored across a coin's face by coin-rolling or coin-wrapping machines. It happens entirely after the coin leaves the Mint — it is post-mint damage (PMD), not a mint error. It has no numismatic value. The groove is recessed (cut in), whereas genuine mint errors from die voids are always raised. Spend the coin.
Are there any valuable George Rogers Clark or Effigy Mounds quarter errors?
No confirmed, catalog-listed major varieties exist for either design as of January 2026. George Rogers Clark quarters show frequent Machine Doubling that is mistaken for a "Double Face" error, but no verified hub-doubled examples have been confirmed. Effigy Mounds quarters sometimes display slight misalignment creating a minor double-rim appearance, but this is within Mint tolerance and adds no value. The intentional concentric circle design elements on Effigy Mounds are often misidentified as die chatter — they are part of the artwork.
What tools do I need to check my 2017 quarters for errors?
Three tools cover the vast majority of checks: (1) A 10x–20x triplet loupe ($10–$20) for distinguishing genuine doubling from machine doubling and identifying die chips. (2) A digital scale accurate to 0.01g (under $15) for weight-based error checks like missing clad layer and silver wrong planchet. (3) A magnet — any refrigerator magnet will do — to screen for steel counterfeits. That's the complete toolkit for home screening of 2017 quarters.

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.
