Rare 2016 Quarter Errors Worth Money (Full List With Pictures)

A 2016-D Theodore Roosevelt quarter struck on a nickel planchet sold on eBay in 2021 for $500. The complete 2016 quarter error list covers nine distinct mint mistakes across the America the Beautiful series, with values ranging from $85 doubled dies to a three-figure off-metal strike. Five different national park designs rolled off the presses that year — Shawnee, Cumberland Gap, Harpers Ferry, Theodore Roosevelt, and Fort Moultrie — and each produced its own set of errors. Here’s every documented mistake, sorted by value, with identification details for each one.

1. 2016 Quarter Doubled Die Error (Up to $85)

A doubled die occurs when the hub impresses its design onto the working die at slightly different angles during manufacturing. The result is a die carrying two overlapping versions of the design, offset from each other.

Every coin struck by that die inherits the same doubling. On 2016 Harpers Ferry quarters, the doubling is most visible on the architectural details of John Brown’s Fort and the reverse inscriptions. The doubling on these ATB quarters tends to be subtle — Class VIII tilted hub varieties rather than the dramatic spread seen on classic doubled dies from the 1950s and 1960s.

Value: In 2019, a 2016-D Harpers Ferry quarter graded MS61 with a doubled die error sold for $85. No major auction house has featured a 2016 ATB doubled die as a headline lot. General market prices for minor doubled dies on ATB quarters run $25–$50 for circulated examples with clear doubling. Strong doubling visible without magnification on uncirculated coins pushes toward $75–$100. The grade and visibility of the doubling together determine the price.

How to Identify: Examine the reverse inscriptions and architectural details under at least 10x magnification. True hub doubling shows rounded, separated secondary images — the letters will have a distinct second outline with depth and dimension.

Focus on HARPERS FERRY, E PLURIBUS UNUM, and the window details of John Brown’s Fort, where doubling is most commonly reported on 2016 quarters.

The critical trap is machine doubling, which is extremely common and worth nothing. Machine doubling creates a flat, shelf-like shadow pushed uniformly to one side of all raised lettering. A genuine doubled die shows rounded notching at specific diagnostic points, not a uniform flat shadow across everything. Compare against known variety photos. Fastest confirmation: rounded secondary images with depth, not flat shelf-like shadows.

2. 2016 Quarter Die Clash Error (Up to $100)

A die clash happens when the obverse and reverse dies strike each other without a planchet between them. The impact transfers a mirror image of each die’s design onto the opposing die face.

Subsequent coins carry ghost images — Washington’s profile faintly visible behind the park scene on the reverse, or park design elements ghosting through the obverse field. On 2016 Harpers Ferry quarters, the most common tell is curved lines from Washington’s portrait appearing in the reverse field near the building. The ghost images are incuse (sunken), not raised, because they’re the inverse of the opposing die’s relief.

Value: In 2020, a 2016-D Harpers Ferry quarter graded MS63 with a die clash error sold on eBay for $100. Circulated examples with visible clash marks generally trade for $25–$50. The strength of the ghost image determines the price — a bold, unmistakable clash on an uncirculated coin is a different proposition from a faint shadow requiring 20x magnification to confirm. Multiple clash impressions from the same die create bolder ghosts and push values higher.

How to Identify: Look for faint design elements that shouldn’t appear on that side of the coin. Washington’s jawline and profile ghosting behind the reverse park design is the most common pattern.

The ghost images appear as incuse (sunken) impressions, not raised. They’re mirror-reversed versions of the opposing die’s design. Use angled lighting — tilt the coin slowly under a desk lamp and watch for outlines emerging in the field. Clash marks often only reveal themselves at specific light angles.

Don’t confuse with strike-throughs, which create blank or weakened areas without any recognizable design. A die clash produces a recognizable reversed mirror image. Fastest confirmation: identifiable reversed ghost of the opposite side’s design, visible under angled light.

3. 2016 Quarter Rim Cud Error (Up to $100)

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

On 2016 Theodore Roosevelt quarters, rim cuds have been documented near various positions around the circumference. The size varies — some are barely noticeable nubs, others are large enough to encroach on nearby lettering. Cuds that eat into UNITED STATES or QUARTER DOLLAR on the reverse attract more collector attention than those sitting in empty space along the rim.

Value: In 2019, a 2016-P Theodore Roosevelt quarter graded MS60 with a rim cud error sold on eBay for $100. Smaller cuds on circulated ATB quarters typically trade for $20–$50. Size, location, and grade together determine the price. Cuds that overlap prominent design elements bring the top end, while small ones near plain rim sections barely attract interest. Large cuds on uncirculated coins can push past $100 on the right day.

How to Identify: Run your finger along the rim. A cud feels like a raised bump that disrupts the smooth, even edge — distinctly different from a ding caused by dropping the coin.

Genuine cuds have a smooth, flat top. They formed under thousands of pounds of striking pressure. Post-mint damage looks rough, jagged, and irregular by comparison.

Check the design elements near the cud. On a genuine example, letters or design features next to the break may appear weakened or distorted because the broken die couldn’t apply full pressure in that area. Examine the opposite side directly behind the cud — a slight depression or weakness in the design at that position helps confirm it. Fastest confirmation: smooth flat-topped bump at the rim with weakened design nearby.

4. 2016 Quarter Struck Through Grease Error (Up to $110)

A struck-through error happens when foreign material gets trapped between the die and planchet at the moment of striking. Grease is the most common culprit — press lubricant pools in die recesses and fills in design detail.

The result is a smooth, blank patch where inscriptions or design elements should be. On 2016 Harpers Ferry quarters, grease fills commonly obscure parts of John Brown’s Fort — the window details, roofline, or surrounding inscriptions disappear into featureless metal. Large grease fills that wipe out an entire word or major section of the building bring the most attention. Small spots that barely affect the design are common and worth very little.

Value: In 2019, a 2016-P Harpers Ferry quarter graded MS62 with a major struck-through grease error sold at an online auction for $110. Minor grease fills on circulated quarters trade for $5–$25 — they’re among the most common ATB quarter errors. Large affected areas covering significant portions of the design on uncirculated coins push $50–$110. The word “major” in the lot description did the heavy lifting on that $110 sale.

How to Identify: Look for a localized area where the design appears weak, mushy, or completely absent — a smooth blank zone surrounded by otherwise normal detail. The boundaries between the struck-through area and normal detail should be relatively sharp.

Grease fills produce featureless, smooth patches. They don’t show texture or embedded material — just blank, flat metal where the grease prevented the die from impressing.

Make sure the weakness isn’t from circulation wear. Strike-throughs affect a specific localized area while wear spreads evenly across all high points. On ATB quarters, check the intricate park design details on the reverse — that’s where grease most often accumulates in the die recesses. Fastest confirmation: sharply defined smooth zone surrounded by normal strike quality.

5. 2016 Quarter “Cat on the Roof” Die Chip Error (Up to $125)

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 2016 Harpers Ferry quarters, a specific die chip became collectible because of where it landed — on top of John Brown’s Fort, the blob of extra metal looks exactly like a cat sitting on the roof. This is a nickname error, similar to the “Extra Leaf” on 2004 Wisconsin quarters or the “Extra Tree” on other ATB designs. The recognizable silhouette gives this otherwise minor die chip outsized collector appeal compared to random chips elsewhere on the coin.

Value: In 2017, a 2016-D Harpers Ferry quarter graded MS60 with the “Cat on the Roof” die chip sold for $125. That’s a premium driven entirely by the visual novelty — a random die chip of similar size in a less interesting location would bring $5–$15. Other 2016 ATB die chips without the cat silhouette trade for $10–$30 depending on size and placement. The nickname gives this variety a built-in collector audience that generic die chips lack.

How to Identify: Flip to the reverse of a 2016 Harpers Ferry quarter and look at the roofline of John Brown’s Fort. The “cat” appears as a small raised blob sitting on top of the roof, roughly resembling a cat in profile — a rounded head and body silhouette.

Use a 5x loupe to confirm. The blob should be raised, smooth, and have the same luster as the surrounding coin — it was struck in during minting. Compare against photos of confirmed “Cat on the Roof” examples online, because the resemblance varies by die state. Early strikes from the chipped die show a clearer cat shape; later strikes may show the chip growing larger and losing definition.

Post-mint damage creates rough, irregular marks. The cat die chip is smooth and rounded. Fastest confirmation: raised blob on the Harpers Ferry building roofline matching the known cat silhouette.

6. 2016 Quarter Die Cap Error (Up to $130)

A die cap starts when a freshly struck coin sticks to the upper die and doesn’t eject. The stuck coin becomes a new striking surface, and the press keeps running.

With each successive strike, the stuck coin curls around the die into a bottle-cap shape. Incoming planchets receive a weak, mirror-image impression from the stuck coin instead of the proper die design. On this 2016-P Harpers Ferry example, the cap produced a ghost-like brockage of the reverse design on subsequent coins. Die caps on modern clad quarters are uncommon because quality control catches most press malfunctions quickly.

Value: In 2020, Heritage Auctions sold a 2016-P Harpers Ferry quarter graded MS63 with a die cap error for $130. That’s modest for a die cap — on older or higher-mintage series, caps routinely sell for $500–$1,500. The lower price here reflects the relatively early-stage cap with mild curvature. General market prices for ATB quarter die caps range from $75–$200. Advanced caps with deep cupping and clear brockage impressions push toward the higher end.

How to Identify: The shape is the giveaway. A die cap coin is not flat — it’s concave, cupped, or bowl-shaped. Place it on a flat surface and it will rock. The rim on one side will be dramatically raised.

One side should show a normal or near-normal design. The other may carry a weak, reversed mirror-image impression from the stuck coin.

Check the rim height — significantly taller than a normal quarter’s rim confirms the cap formation. Don’t confuse with a simple brockage from a single extra strike, which stays flat. A cap error is always cupped. Weigh it: should still be approximately 5.67 grams since it’s a proper quarter planchet. Fastest confirmation: cupped bottle-cap shape plus reversed incuse design on one side.

7. 2016 Quarter Missing Clad Layer Error (Up to $150)

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.

This 2016-P Harpers Ferry example had both a missing clad layer and an improper annealing error on the same coin — a double defect. The exposed copper core gave one side a vivid reddish-brown color, while the botched annealing added unusual toning in yellow, black, and purple tones across the surface. The combination of two distinct errors on a single coin made it more interesting than either defect alone.

Value: In 2017, Heritage Auctions sold a 2016-P Harpers Ferry quarter graded MS60 with a combined missing clad layer and improperly annealed error for $150. That’s the highest confirmed auction price from a major house for any individual 2016 ATB quarter error. Standalone missing clad quarters without the annealing component typically trade for $50–$100. The dual-error nature of this particular coin drove the premium above the normal range.

How to Identify: Color is the first clue. One or both sides will appear copper — brassy orange to dark brown — instead of the standard silver tone. Additional annealing defects may add unusual toning: yellow, gray, black, or purple patches.

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, not a genuine mint error.

Check the rim for a missing or thin cladding band. Examine the opposite side — the design may appear weak where the thinner planchet couldn’t fill the die cavities. Acid-treated fakes retain full detail at normal weight. Fastest confirmation: copper color plus weight well below 5.67 grams.

8. 2016 Quarter Off-Center Strike Error (Up to $265)

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 2016-P Theodore Roosevelt quarter, the design shifted toward one edge, leaving a crescent of blank metal on the opposite side. Off-center percentage drives the value. A 10% shift on an ATB quarter adds modest premium; a 30%+ displacement with a readable date and identifiable park design is a different category entirely. The Theodore Roosevelt design — with its detailed bison and river scene — makes partial strikes particularly visual.

Value: In 2017, a 2016-P Theodore Roosevelt quarter graded MS60 with an off-center strike error sold for $265. Minor off-center strikes under 10% on ATB quarters trade for $30–$50. Dramatic 30%+ off-centers with visible dates push $100–$265. Without a readable date, even impressive off-centers lose most of their appeal. The $265 price represents the high end for documented 2016 ATB quarter off-center sales.

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.

Don’t confuse with a Misaligned Die (MAD) error. A MAD shows the complete design with uneven rim width — nothing is missing. An off-center strike always has blank planchet showing.

The blank area should be smooth with no design ghosting. Post-mint damage from machinery creates uneven distortion with scratches. Genuine off-center strikes have clean unstruck areas. Check whether the date and the park design are both identifiable — on ATB quarters, the reverse park identity adds value because collectors want to know which of the five 2016 designs it is. Fastest confirmation: clean blank crescent with the design clearly shifted and partially missing.

9. 2016 Quarter Struck on Nickel Planchet Error (Up to $500)

An off-metal error occurs when a planchet intended for one denomination gets fed into the wrong press. In this case, a Jefferson nickel blank ended up in the quarter press and got struck with 2016 Theodore Roosevelt quarter dies.

A nickel planchet measures 21.21mm and weighs 5.00 grams; a quarter planchet is 24.26mm and weighs 5.67 grams. Because the nickel blank is over 3mm smaller, the quarter dies can’t fully cover it. LIBERTY gets cut off at the top of Washington’s portrait, QUARTER disappears from the reverse, and the raised rim is incomplete. The reeded edge from the quarter’s collar die still forms — but on a too-small coin, creating a distinctive mismatch.

Value: In 2021, a 2016-D Theodore Roosevelt quarter struck on a nickel planchet, graded MS62, sold on eBay for $500 — the highest documented price for any 2016 ATB quarter error. Off-metal quarter-on-nickel errors generally range from $300–$700 depending on grade and visual impact. The eBay source makes this price harder to verify than a Heritage or Stack’s Bowers record, but the error type is well-established and consistently commands three-figure premiums.

How to Identify: Size is the first giveaway. The coin will be noticeably smaller than a standard quarter when placed side by side. Measure with calipers: 21.21mm versus the standard 24.26mm — over 3mm short.

Weigh it. A normal quarter weighs 5.67 grams. A quarter struck on a nickel planchet weighs 5.00 grams — the 0.67-gram difference is easily detectable on a digital scale accurate to 0.01g.

The design will be incomplete. LIBERTY at the top of Washington’s head and QUARTER DOLLAR on the reverse will be partially or fully missing because the smaller planchet ran out of metal. The edge may show partial reeding from the quarter collar die, but it won’t wrap all the way around properly. Don’t confuse with a worn or damaged quarter — the missing design elements follow a clean, circular boundary where the planchet ended. Fastest confirmation: 21.21mm diameter, 5.00g weight, incomplete design with clean circular cutoff.

Conclusion

The 2016 ATB quarter error range runs from $85 doubled dies to a $500 off-metal struck on a nickel planchet. The values are lower than other modern denominations — no 2016 quarter error has cracked $1,000 at a documented auction. The “Cat on the Roof” die chip on Harpers Ferry quarters at $125 is the most collectible variety with a built-in nickname, while the off-metal and off-center strikes represent the highest raw dollar values. A digital scale, a 10x loupe, and calipers cover identification basics for all nine error types listed here.
