Rare 2005 Quarter Errors Worth Money (Full List With Pictures)

A 2005-P Minnesota quarter with a cloth impression struck into its surface sold for $1,300 at Heritage Auctions in 2023. That coin started as a 25-cent piece.

The full range of 2005 quarter errors spans from about $20 for common grease fills to well over $1,000 for dramatic strike errors across all five state designs — California, Minnesota, Oregon, Kansas, and West Virginia. Below is every major error from the 2005 series, sorted from least to most valuable, with auction records and identification tips for each.

1. 2005 Kansas Quarter “In God We Rust” Grease-Filled Die Error (Up to $100)

Die lubricant mixed with metal dust packed into the letter cavity for the “T” in “TRUST” on the obverse die at the Philadelphia Mint. When the die struck each blank, grease blocked metal from filling that space, so the motto came out reading “IN GOD WE RUST.”

The severity varies — some coins show a faint shadow of the “T,” while others have it completely gone. This error only affected 2005-P Kansas quarters, and it became one of the most talked-about modern mint mistakes because the missing letter changed the meaning of a national motto.

Value: Circulated examples with a partially visible “T” sell for $20–$30 on eBay. Clean uncirculated coins with the “T” fully absent bring $50–$100, depending on overall surface quality and luster.

The degree of fill is the primary price driver — a coin with a completely invisible “T” and sharp surrounding details will always outperform one where a faint ghost of the letter remains.

How to Identify: Use a 5x or 10x loupe and examine the obverse motto “IN GOD WE TRUST.” On error coins, the first “T” in “TRUST” will appear dimmed, partially filled, or entirely missing.

The rest of the lettering and devices should remain sharp and fully struck — that contrast is the key diagnostic. If the “T” is weak but surrounding details are also mushy, you likely have a weak strike, not a grease fill.

Confirm the P mint mark on the obverse, since this error is tied exclusively to the Philadelphia facility. Weight should be standard at 5.67 grams.

Compare your coin side by side with a normal 2005-P Kansas quarter. The fastest confirmation is a missing “T” with crisp detail everywhere else on the coin.

2. 2005 Kansas Quarter “Humpback Bison” Die Break Error (Up to $100)

A crack formed inside the working die at the Philadelphia Mint, right over the area corresponding to the bison’s back on the reverse design. When the cracked die struck blanks, excess metal squeezed through the gap and left a raised lump on the bison’s back — making it look like the animal grew a hump overnight.

ANACS recognized this as the “Humpback Bison” error, while PCGS labels it as a reverse die break. The bump is not subtle — anyone familiar with the normal Kansas bison will notice it immediately.

Value: Circulated Humpback Bison quarters sell for $15–$20 on the secondary market. Uncirculated examples in MS63–MS65 bring $50–$100, with PCGS or NGC certified specimens at MS65+ occasionally exceeding $100 at auction.

PCGS-graded MS67 examples are rare and command the strongest premiums — one sold for just over $100 in recent years. Like the “In God We Rust” error, this one is exclusive to 2005-P Kansas quarters from the Philadelphia Mint.

How to Identify: Flip the coin to the reverse and look at the bison’s back. On a normal Kansas quarter, the back is smooth with a gentle curve.

On the Humpback variety, a distinct raised mass of metal sits on top of the bison’s profile, typically between the shoulders and the hindquarters. Tilt the coin under strong raking light to make the raised area pop.

The lump should be smooth and rounded on top — consistent with metal that flowed through a die crack under pressure. If the bump looks rough, scratched, or has sharp edges, it is likely post-mint damage.

Always confirm the P mint mark. The fastest check is comparing the bison’s back profile against any normal 2005 Kansas quarter.

3. 2005 Oregon Quarter Doubled Die Reverse Error (Up to $560)

During die manufacturing, the hub impressed the Oregon reverse design into a working die at two slightly different angles. Every coin struck by that flawed die inherited the same doubled image — a mechanical duplication baked into the die itself, not a problem with individual strikes.

On the 2005-D Oregon quarter, doubling appears in the reverse lettering and portions of the Crater Lake design. This is a true hub-doubling variety, which means every affected coin shows identical doubling in the same locations.

Value: A 2005-D Oregon quarter graded MS64 with a doubled die reverse sold for $560 at Heritage Auctions in 2022. Lower-grade circulated examples with visible doubling trade in the $30–$75 range, depending on the strength and clarity of the doubled elements.

The Denver mint mark matters — this particular DDR is documented on D-mint coins. Certification by PCGS or NGC with the DDR attribution significantly increases resale value over raw examples.

How to Identify: Use a 10x loupe and examine the reverse lettering, especially “OREGON” and “CRATER LAKE.” True doubled die doubling appears as rounded, fully formed duplicate letters with clear separation between the primary and secondary images.

Compare this against machine doubling, which produces flat, shelf-like shadows that look smeared rather than stamped twice. Machine doubling has no collector premium.

Check both the lettering and the design elements around Crater Lake for consistent directional doubling. The doubling should appear in the same direction across multiple elements.

Weight and diameter remain standard. The fastest way to confirm: look for two distinct, rounded outlines on the same letter — if both outlines are sharp and three-dimensional, it is a genuine doubled die.

4. 2005 Minnesota Quarter Extra Tree Doubled Die Reverse Error (Up to $800)

The Philadelphia Mint’s single-squeeze hubbing process went wrong when the hub contacted a slightly tilted die blank and then snapped into alignment under pressure. That rotational smear duplicated the spruce tree design near the center of the reverse, creating what collectors call the “Extra Tree” — a ghostlike additional spruce visible to the right of the existing tree line.

PCGS designated the major variety as FS-801 (DDR-001). Over 50 distinct doubled die pairings have been cataloged for the 2005 Minnesota quarter, but FS-801 is the only one commanding real money — everything else is noise.

Value: The PCGS price guide lists FS-801 at around $74 in MS60 and $90 in MS65. Certified MS67 examples have reached approximately $800 at auction.

A 2005-P Minnesota FS-801 graded MS63 sold for about $51 at GreatCollections. Minor DDR varieties (FS-802 through FS-805 and beyond) sell for $5–$50 — the specific attribution matters enormously, and an unattributed minor variety and a confirmed FS-801 can differ by $200 or more.

How to Identify: Flip to the reverse and count four spruce trees to the right of the Minnesota state outline. Immediately right of that fourth tree, look for three ghostlike spruce boughs — a partial, raised duplicate tree floating in the field.

On the FS-801, these boughs are distinct and visible under 5x magnification. Minor varieties show only faint shadowing or a small nub in the same area.

Machine doubling looks flat and shelf-like; genuine DDR doubling is rounded and three-dimensional. Confirm the P mint mark — the major variety is a Philadelphia strike.

Weight is standard at 5.67 grams. The fastest check: compare the tree line on your coin to a normal 2005-P Minnesota quarter — the extra tree jumps out once you know where to look.

5. 2005 Oregon Quarter Triple Clipped Planchet Error (Up to $910)

Before striking, quarter blanks are punched from a long strip of metal by a blanking press. Normally each punch lands on fresh metal, but when the strip feeds improperly, the punch overlaps a hole left by a previous cut, producing a blank with a curved bite taken out of its edge.

On this Oregon quarter, the strip malfunctioned three times — producing a blank with three separate missing sections along its rim. Triple clips are far scarcer than single clips because each additional overlap requires a separate feeding malfunction during the same production sequence.

Value: A 2005-P Oregon quarter with a triple clipped planchet error, graded MS62 by PCGS, sold for $910 at GreatCollections in 2023. Single-clip errors on 2005 quarters typically bring $20–$50 in circulated grades, and double clips push into the $75–$150 range.

The jump to a triple clip reflects genuine scarcity — most collectors never encounter one, and the visual impact of three missing edge sections drives strong demand at auction.

How to Identify: Look at the coin’s edge for curved, concave bites where metal is missing. A genuine clip will show a smooth, unstruck surface along the missing area, and the Blakesley effect often produces a weak spot on the rim directly opposite each clip.

Weigh the coin — a triple-clipped quarter will be noticeably under the standard 5.67 grams, sometimes by 0.3–0.5 grams or more depending on clip size. Measure the diameter with calipers at multiple angles; it will be inconsistent.

The reeded edge will be absent or incomplete where the clip occurred. Do not confuse a genuine clip with post-mint damage from pliers or a vice, which leaves sharp, angular edges rather than smooth curves.

The fastest confirmation: three separate concave bites with smooth edges plus an underweight reading on a digital scale.

6. 2005 California Quarter Rotated Die Error (Up to $950)

A normal quarter has its obverse and reverse dies aligned 180 degrees apart — flip it top to bottom and both sides are right-side up. A rotated die error happens when one die is installed at the wrong angle, causing the reverse to appear tilted relative to the obverse.

On the 2005-D California quarter, rotated die errors have been documented at varying degrees. The more severe the rotation, the more obvious and valuable the error — a 45-degree rotation is dramatic enough to notice without tools.

Value: A 2005-D California quarter graded MS64 with a 45-degree rotated die error sold for $950 at Heritage Auctions in 2023. Smaller rotations of 10 to 15 degrees trade for considerably less, typically $30–$75.

The price curve steepens sharply above 30 degrees. A full 180-degree rotation would be the rarest and most valuable, but no certified example from the 2005 California issue has been documented at that extreme.

How to Identify: Hold the coin with the obverse upright and flip it along the vertical axis, like turning a page. On a normal quarter, Washington faces left on top and the reverse design appears right-side up on the bottom — if the reverse is tilted, you have a rotation.

Estimate the degree by comparing against a clock face — 90 degrees means the reverse is sideways. Use a protractor or rotation gauge for precision.

The coin’s weight (5.67 grams) and diameter (24.26 mm) remain standard, and edge reeding is normal. To rule out an altered coin, check that the devices on both sides are sharply struck with no signs of tooling, adhesive, or separation at the rim.

The fastest confirmation: flip test against a known normal quarter and estimate the rotation angle.

7. 2005 California Quarter Missing Clad Layer Error (Up to $1,010)

Standard quarters are three-layer sandwiches: a copper core bonded between two outer layers of cupronickel. During planchet production, impurities or contamination in the metal alloy can weaken the bond between layers.

When that bond fails before striking, one or both outer layers peel away, and the exposed copper core gets struck by the dies. On the 2005-D California quarter, partial missing clad layer errors show the orange-brown copper core on one face while the other retains its normal silver appearance.

Value: A 2005-D California quarter graded MS65 with a partial missing clad layer sold for $1,010 at a GreatCollections auction in 2020. The PCGS certification was critical to that price.

Partial missing clad errors in lower grades bring $50–$200, with the size of the missing area and the visual contrast driving the price. Full missing clad layers — where the entire face is exposed copper — are scarcer and command the highest premiums.

How to Identify: The first clue is color. If one side of your quarter is copper-brown instead of silver-gray, you may have a missing clad layer.

Weigh the coin — a quarter missing one full clad layer will weigh approximately 4.7 grams instead of the standard 5.67 grams. That weight difference is the most reliable diagnostic.

Check the edge: on a normal quarter, you can see the copper core as a thin line sandwiched between two silver layers. On a missing clad coin, the copper extends to the surface on the affected side, and the edge layering is visibly asymmetrical.

Do not confuse this with an acid-dipped coin, which will weigh close to normal, show mushy or corroded details, and have discoloration covering the reeded edge. The fastest check: weigh it — if it is significantly under 5.67 grams with sharp details on the copper face, it is real.

8. 2005 Minnesota Quarter Double Strike Error (Up to $1,115)

A double strike happens when the coin press fails to eject a finished coin and fires again. That second blow hits the coin in a slightly different position, producing two overlapping but offset impressions of the design on the same side.

On the 2005-P Minnesota quarter, double strikes have been documented on the obverse — two complete images of Washington’s portrait overlap on a single coin. The visual effect is unmistakable, which is why these errors draw serious collector interest.

Value: A 2005-P Minnesota quarter graded MS65 with an obverse double strike sold for $1,115 at auction. Lower-grade examples with visible offset typically bring $200–$500, depending on the degree of separation between the two impressions.

The more dramatic the separation, the higher the price. Coins combining a double strike with an off-center shift qualify as combination errors and can push well above $1,000.

How to Identify: Look at the obverse for two overlapping images of Washington’s portrait. Both impressions should be fully formed with sharp details — one slightly offset from the other.

The degree of offset varies; some show only a slight shadow, while others display two clearly separated profiles. Check the reverse for corresponding doubled design elements.

Weigh the coin — it should be standard at 5.67 grams since the blank was normal, just struck twice. If the coin also appears slightly oval or expanded, it may be a combination double strike and broadstrike.

Do not confuse a double strike with a doubled die: a doubled die affects every coin from that die identically, while a double strike is unique to the individual coin. The fastest way to tell — a double strike shows two complete, full-strength impressions offset from each other, while a doubled die shows partial duplication in specific areas.

9. 2005 Kansas Quarter Die Cap Error (Up to $1,220)

A die cap forms when a freshly struck coin fails to eject and sticks directly to the upper die. The stuck coin acts like a cap over the die face, and as the press keeps running, it strikes new blanks against the bottom of the stuck coin instead of the die.

With each successive strike, the stuck coin deforms further — curving upward around the die edges into a bowl or thimble shape. Late-stage die caps are deeply cupped and paper-thin at the rim.

Value: A 2005-D Kansas quarter graded MS65 with a die cap error sold for $1,220 on eBay in 2020. Die cap errors are scarce on modern quarters because the Mint installed sensor systems in 2002 to detect and eject mis-fed coins — any die cap that escaped post-2002 production represents a failure of those safeguards.

Prices for die caps on state quarters generally range from $500 to $1,500 depending on the stage and visual impact of the deformation.

How to Identify: A genuine die cap has a distinctive cupped or bowl shape — the coin curves upward around its edges, and one side shows a mirrored, incuse version of the design from being pressed against subsequent blanks. The die side retains a relatively normal appearance, though it may show progressive weakness from repeated strikes.

Weigh the coin; it should be close to 5.67 grams unless struck on a clipped blank. The edge will lack normal reeding and may appear stretched or irregular.

Verify that the incuse design on the concave side is a true brockage impression — it should be a mirror image, reading backward. Post-mint damage from a vice or press does not produce a readable mirror-image brockage.

The fastest confirmation: a cupped coin with a readable, backward mirror-image design on the concave side.

10. 2005 West Virginia Quarter Off-Center Broad Strike Error (Up to $1,230)

This coin carries two errors at once. The blank was struck outside the retaining collar — a broad strike — which means the metal spread outward unconstrained, making the finished coin wider and thinner than normal.

At the same time, the blank was not centered between the dies — an off-center strike — so the design is shifted toward one edge, with a crescent of blank metal on the opposite side. The 2005-P West Virginia quarter is a well-documented example of both errors occurring simultaneously.

Value: A 2005-P West Virginia quarter graded MS63 with an off-center broad strike error sold for $1,230 at GreatCollections in 2021. Off-center errors alone are valued by the percentage of displacement: 10–15% off-center brings $50–$75, while 50%+ can reach $150–$300.

The broad strike component adds a premium on top of that. Retaining a visible date is critical — coins with the date missing are worth significantly less regardless of the offset percentage.

How to Identify: The coin will appear larger than a normal quarter — measure with calipers and compare against the standard 24.26 mm. The design is visibly shifted toward one edge, with a blank crescent on the opposite side.

The reeded edge will be absent or flattened because no collar constrained the metal during striking. Weigh the coin; it should be close to 5.67 grams since the blank was standard-weight — only its shape and size changed.

To estimate the off-center percentage, measure the blank crescent relative to the total coin surface. Check that the struck portion shows sharp, fully formed details — the design is simply in the wrong position, not weak.

Post-mint damage from rolling or squeezing produces distortion without clean, blank crescents. The fastest confirmation: an oversized coin with a clean blank crescent, no reeding, and sharp design details on the struck area.

11. 2005 Minnesota Quarter Struck Through Cloth Error (Up to $1,300)

A struck-through error occurs when a foreign object sits between the die and the blank at the moment of striking. In this case, a piece of cloth absorbed part of the strike force and left its woven texture physically impressed into the coin’s surface.

On the 2005-P Minnesota quarter, the cloth impression is clearly visible as a fabric weave pattern pressed into the metal. Cloth struck-throughs are scarcer than grease fills because the fabric must be large enough to stay in position during a full-pressure strike.

Value: A 2005-P Minnesota quarter graded MS65 with a cloth struck-through error sold for $1,300 at Heritage Auctions in 2023. That remains the highest documented auction price for any individual 2005 state quarter error.

Struck-through grease errors from the same year typically sell for $10–$50. The cloth variant brings a substantial premium because the woven texture is visually distinctive and photographically verifiable — grease fills are common, cloth impressions are not.

How to Identify: Examine both sides of the coin under 10x magnification for an impressed fabric weave pattern — a grid-like texture of tiny rows and columns pressed into the metal surface. The pattern should be recessed, not raised, since the cloth prevented full metal flow into the die.

The affected area will show softened or missing design details where the cloth absorbed the strike, but surrounding areas should be fully struck. Weigh the coin at 5.67 grams and confirm standard 24.26 mm diameter — the blank itself is normal.

Do not confuse cloth struck-throughs with environmental damage, corrosion, or contact marks, which produce irregular pitting rather than a uniform texture. The weave pattern will have a consistent, repeating structure that matches textile geometry.

The fastest confirmation: a uniform, recessed fabric weave pattern covering a defined area of the coin, with sharp details on the unaffected portions.

Conclusion

The 2005 state quarter series covers a wide error value range. Common Kansas grease fills start around $20, while named die breaks like the Humpback Bison sit in the $15–$100 range.

Mid-tier errors — doubled dies, clipped planchets, rotated dies — run $50 to $1,000 with the right grade and attribution. The top-end errors have all cleared $1,000 at auction, topped by a $1,300 cloth struck-through on a Minnesota quarter.
