Rare 2015 Quarter Errors Worth Money (Full List)

A 2015-P Blue Ridge Parkway quarter with a 25% off-center strike sold at Heritage Auctions in 2016 for $405. The complete 2015 quarter error list covers nine distinct mint mistakes across the America the Beautiful series, with values ranging from $100 doubled dies to a three-figure off-center that left a quarter of the coin blank. The Mint struck nearly three billion quarters that year — the highest production volume in the entire ATB program — across five designs: Homestead, Kisatchie, Blue Ridge Parkway, Bombay Hook, and Saratoga. Here’s every documented error, sorted by value, with auction records and identification details.

1. 2015 Quarter Doubled Die Error (Up to $100)

A doubled die occurs when the hub impresses its design onto the working die at slightly different positions during manufacturing. Every coin struck by that die inherits the same overlapping design.

On this 2015-D Kisatchie National Forest quarter, the doubling appeared on both the obverse and reverse simultaneously. The obverse shows doubling on LIBERTY and IN GOD WE TRUST, while the reverse Kisatchie forest scene shows overlapping inscriptions. Dual-side DDO+DDR combinations are less common than single-side varieties because both the obverse and reverse dies need to have been affected. The Kisatchie design’s fine tree and forest detail makes even subtle doubling visible.

Value: A 2015-D Kisatchie quarter graded MS64 with an obverse and reverse doubled die error sold for $100. Minor doubled dies on circulated ATB quarters trade for $25–$50. Strong doubling visible under low magnification on uncirculated coins pushes toward $75–$100. The dual-side DDO+DDR combination helped this example reach the top of the range.

How to Identify: Use at least 10x magnification. On the obverse, check LIBERTY and IN GOD WE TRUST letter by letter for secondary outlines. On the reverse, examine the Kisatchie inscriptions and tree details for overlapping impressions.

True hub doubling shows rounded, separated secondary images with depth. Machine doubling — flat, shelf-like shadows pushed to one side — is extremely common on 2015 quarters and worth nothing.

Check both sides. If only one side shows doubling, it’s still a DDO or DDR. If both show it, the coin is more valuable. Compare against known 2015 variety photos. Fastest confirmation: rounded secondary images with depth at known diagnostic points, not flat uniform shadows.

2. 2015 Quarter Die Cud Error (Up to $100)

A die cud forms when a piece of the die’s surface breaks away, leaving a void that fills with metal during each subsequent strike. The filled void transfers as a raised lump on every coin the damaged die produces.

On this 2015-P Saratoga quarter, the cud appeared on the coin’s surface rather than at the rim — an interior die break rather than the more common rim cud. Interior cuds sit within the design field, disrupting whatever elements lie beneath them. The Saratoga reverse — showing the Surrender of General Burgoyne — features detailed figurework where an interior cud creates obvious visual disruption against the historical scene.

Value: In 2018, a 2015-P Saratoga quarter graded MS60 with an interior die cud error sold for $100. Interior cuds on ATB quarters generally trade for $40–$100 depending on size and placement. Cuds that sit on top of major design elements bring the top end. Small cuds in empty field areas barely attract interest.

How to Identify: Look for a raised, irregular lump on the coin’s surface that doesn’t match the original design. Interior cuds sit within the design field, not at the rim. The lump should be smooth on top — it formed under full striking pressure.

Don’t confuse with die chips, which are smaller and more uniform. Interior cuds are larger and more irregularly shaped because they result from a bigger piece of the die breaking away.

Post-mint damage creates rough, irregular marks. A genuine cud is smooth, raised, and has the same luster as the surrounding coin. Design elements beneath the cud will be obscured or absent. Fastest confirmation: large smooth raised lump within the design field, with disrupted design underneath.

3. 2015 Quarter Re-Punched Mint Mark Error (Up to $115)

A re-punched mint mark occurs when the mintmark punch strikes the die more than once at slightly different positions. The result is a doubled or offset “P” or “D” visible on the finished coin.

On this 2015-P Kisatchie quarter, the “P” mint mark shows a secondary impression from the second punch — a shadow or partial outline adjacent to the primary letter. By 2015, mintmark application was largely automated, making RPMs less frequent than on earlier quarters where hand-punching created more misalignments. The Kisatchie design from Louisiana produced the most documented variety errors in the 2015 series.

Value: In 2018, GreatCollections auctioned a 2015-P Kisatchie quarter graded MS63 with a re-punched mint mark error for $115. RPMs on modern quarters without strong separation trade for $10–$50. Well-separated RPMs with clear doubling on certified coins push $75–$115. Proper variety attribution — matching the RPM to a cataloged listing — unlocks the full premium.

How to Identify: Focus on the mint mark on the obverse, below Washington’s ponytail. Use at least 10x magnification and look for doubling, shadowing, or offset around the “P.”

A genuine RPM shows a secondary impression with the same raised profile as the primary mintmark. The most valuable examples show clear separation where you can see two distinct letter outlines.

Don’t confuse with machine doubling on the mintmark, which creates a flat shelf-like shadow on one side. A true RPM shows rounded, three-dimensional secondary impressions. Fastest confirmation: raised secondary mintmark impression with rounded depth matching the primary letter.

4. 2015 Quarter Rim Cud Error (Up to $115)

A rim cud forms when a chunk of the die’s edge breaks away completely. Metal flows into the void during striking, creating a raised bump along the coin’s circumference.

Unlike an interior die cud — which sits within the design field — a rim cud attaches to the rim itself, extending the coin’s profile outward at one point. On this 2015-P Homestead quarter, the rim cud appeared as a raised, flat-topped mass along one section of the edge. The Homestead design from Nebraska shows a cabin and fence that provide good visual reference points for identifying where the cud disrupts the normal rim line.

Value: In 2020, GreatCollections auctioned a 2015-P Homestead quarter graded MS62 with a rim cud error for $115. Small rim cuds on circulated ATB quarters trade for $20–$50. Larger cuds that encroach on prominent lettering push $60–$115. Size and location together determine the price.

How to Identify: Run your finger along the rim. A rim cud feels like a raised bump that disrupts the smooth edge. Genuine cuds have a flat, smooth top — they formed under striking pressure.

Post-mint damage creates rough, irregular bumps. Check the design elements near the cud — letters or design features adjacent to the break may appear weakened because the broken die couldn’t apply full pressure.

Examine the opposite side behind the cud for a slight depression or weakness. Rim cuds must be attached to the rim — raised lumps floating in the design field are interior cuds, not rim cuds. Fastest confirmation: smooth flat-topped bump attached to the rim with weakened design adjacent.

5. 2015 Quarter Die Chip “Two Eyes on Bird” Error (Up to $120)

Die chips form when small fragments break off the striking die’s surface. Metal fills the void and transfers as a raised blob onto every coin struck by that die.

On 2015-D Bombay Hook National Wildlife Refuge quarters, a specific die chip landed on the reverse bird’s head in exactly the right position to create the illusion of a second eye. The Bombay Hook design features a great blue heron, and the chip — sitting just behind the bird’s actual eye — makes the heron appear to have two eyes visible simultaneously. This is a nickname error, joining the “Cat on the Roof,” “Scarface,” “Alligator Eye,” and “Floating Bottle” in the growing catalog of visually named die defects.

Value: In 2017, Heritage Auctions sold a 2015-D Bombay Hook quarter graded MS63 with the “Two Eyes on Bird” die chip error for $120. Generic die chips on 2015 quarters without a recognizable shape trade for $5–$30. The nickname drives the premium — a chip of identical size anywhere else on the coin would bring a fraction of this price. The visual novelty of a two-eyed heron gives this variety a built-in collector audience.

How to Identify: Flip to the reverse of a 2015-D Bombay Hook quarter and examine the great blue heron’s head area under a loupe. The “second eye” appears as a small raised blob positioned behind the bird’s actual eye, creating the illusion of a second eye visible in profile.

The blob should be raised and smooth — it formed during striking. Compare against photos of confirmed “Two Eyes on Bird” examples online, because the chip needs to be in the correct position to qualify. Not every die chip on a Bombay Hook quarter is the Two Eyes variety — only those sitting in the specific position behind the heron’s eye.

Post-mint damage creates rough marks. The die chip should have matching luster. Fastest confirmation: raised blob behind the heron’s eye creating a visible second eye in the correct position.

6. 2015 Quarter Missing Clad Layer Error (Up to $125)

Washington quarters are three-layer coins — a copper core between two outer skins of 75% copper / 25% nickel alloy. When contaminants prevent proper bonding at the strip mill, one or both outer layers can separate.

On this 2015-P Homestead quarter, the missing clad layer exposed the copper core on the obverse, turning Washington’s portrait a vivid reddish-brown. The reverse retained its normal silver appearance, creating a striking two-tone effect — copper on one side, silver on the other. This particular example showed a partial missing clad, meaning not the entire obverse lost its layer. Full missing clad commands higher premiums.

Value: In 2020, a 2015-P Homestead quarter graded MS65 with a partial obverse missing clad layer sold on eBay for $125. Circulated examples with smaller areas of exposed copper trade for $30–$75. Certified coins with full missing clad on one side push above $125. Dual missing clad — both sides showing copper — would command well above $200 but is exceptionally rare.

How to Identify: Color is the first clue. One side will appear copper — brassy orange to dark brown — instead of the standard silver.

Weigh it. A standard quarter weighs 5.67 grams. A coin missing one clad layer will be noticeably lighter — roughly 4.9–5.2 grams. If your copper-colored quarter weighs the full 5.67 grams, it’s likely acid-treated.

Check the rim for a thin profile or absent cladding band. Examine the opposite side — the design may appear weak where the thinner planchet couldn’t fill the die. Fastest confirmation: copper color plus weight well below 5.67 grams.

7. 2015 Quarter Struck Through Error (Up to $230)

A struck-through error happens when a foreign object gets trapped between the die and planchet during striking. The object blocks part of the design from fully impressing onto the coin.

On this 2015-D Kisatchie quarter, the foreign material left a significant impression on the coin’s surface — large enough and clear enough to command $230. Kisatchie’s detailed forest scene with its tall pines and woodland undergrowth provides a complex design background that makes struck-through impressions particularly visible. The Kisatchie design produced three of the nine errors on this list, suggesting its dies saw heavier use or encountered more contamination than the other four 2015 designs.

Value: In 2019, a 2015-D Kisatchie quarter graded MS60 with a struck-through error sold for $230. Minor strike-throughs on circulated ATB quarters trade for $10–$50. Dramatic examples with large, clearly identifiable impressions on uncirculated coins push $100–$230. Retained strike-throughs — where the foreign material is still embedded — command the highest premiums in this category.

How to Identify: Look for an impression or mark on the coin that doesn’t match the standard design. The mark may appear as a thin line (hair or fiber), an irregular patch (debris), or a textured area (cloth).

The impression should sit within the coin’s surface — pressed in during striking — not on top of it. The area around the impression may show slightly weakened design where the foreign object partially blocked the die.

Don’t confuse with post-mint scratches, which cut into the surface with metal displacement. A struck-through impression is smooth and consistent. Fastest confirmation: foreign impression pressed into the surface with matching design weakness around it.

8. 2015 Quarter Misaligned Die Error (Up to $315)

A misaligned die error happens when the dies aren’t properly centered during installation. The design on a misaligned die coin remains complete — unlike an off-center strike, nothing is missing. The entire image sits slightly off-center within the rim.

On this 2015-D Bombay Hook quarter, the misalignment shifted the design enough to create visibly uneven rim width — one side noticeably wider than the other. The Bombay Hook reverse, featuring the great blue heron in a detailed marsh landscape, made the misalignment particularly visible because the bird’s vertical pose provided a clear reference line for alignment.

Value: In 2020, a 2015-D Bombay Hook quarter graded MS64 with a misaligned die error sold on eBay for $315. Minor misalignments on circulated ATB quarters trade for $10–$50. Dramatic misalignments visible to the naked eye on uncirculated coins push $100–$315. The MS64 grade and obvious visual shift drove this example to the top.

How to Identify: Examine the rim width around the entire circumference. On a properly struck coin, the rim is uniform. A misaligned die coin shows one side noticeably wider while the opposite side narrows.

The full design will be present — nothing missing. This is the critical distinction from an off-center strike, which always has blank planchet showing and part of the design gone. A misaligned die coin has everything, just shifted.

The uneven rim should be consistent — wider on one side, narrower on the opposite. Post-mint damage creates irregular distortion, not the symmetrical shift of a die misalignment. Fastest confirmation: complete design present with obviously uneven rim width around the coin.

9. 2015 Quarter Off-Center Strike Error (Up to $405)

Off-center strikes happen when the planchet isn’t seated properly in the striking chamber. The die comes down, but the blank has shifted — only part of it catches the full impression.

On this 2015-P Blue Ridge Parkway quarter, the design shifted 25% off-center, leaving a substantial crescent of blank metal on one side while pushing Washington’s portrait toward the opposite edge. The Blue Ridge Parkway reverse — showing the viaduct curving through the Appalachian Mountains — loses a section of its sweeping design to the blank crescent, making the off-center visually dramatic. At 25%, the shift is unmistakable. Heritage Auctions sold this one in 2016 for $405.

Value: In 2016, Heritage Auctions sold a 2015-P Blue Ridge Parkway quarter graded MS60 with a 25% off-center strike for $405 — the highest confirmed price for any 2015 ATB quarter error. Minor off-center strikes under 10% trade for $15–$45. Dramatic 20–35% off-centers with visible dates command $100–$405. Without a readable date, even impressive off-centers lose most of their value.

How to Identify: Look for a clean crescent of blank, featureless metal on one side. The design will be shifted toward the opposite edge, with part of the lettering or portrait cut off. Both obverse and reverse shift the same direction.

At 25%, the crescent is obvious and covers a large area. Don’t confuse with a Misaligned Die (MAD) error — listed above — which shows the complete design with uneven rim but nothing missing. An off-center always has blank planchet showing.

On 2015 ATB quarters, check which reverse design is identifiable. Collectors want design-specific attribution — a Blue Ridge Parkway off-center is worth more when the viaduct is recognizable. Fastest confirmation: clean blank crescent with the design shifted and date readable.
