Rare 2015 Dime Errors Worth Money (Full List With Pictures)

A 2015-P Roosevelt dime with an off-center strike sold for $430 at Heritage Auctions in 2018. That price came from a coin most people would drop into a parking meter without thinking twice.

This 2015 dime error list covers 12 known minting mistakes worth anywhere from $5 to $430, depending on error type and condition. Here is what to look for and what each one actually sells for.

1. 2015 Dime Struck Through Grease Error (Up to $50)

Grease or lubricant from the coining press builds up on the die face and prevents metal from filling the design during striking. The affected area comes out flat, mushy, or completely blank.

On 2015 dimes, this most often hits Roosevelt’s hair detail, the torch flame, or the lettering in “LIBERTY.” A thin film might only soften a few letters, while a heavy buildup can erase an entire side of the coin.

Light grease fills are among the most common modern dime errors. The ones worth chasing are heavy fills that obliterate major design elements.

Value: No specific 2015 grease strike-through has appeared at a major auction house. Minor examples with a few soft letters sell for $3 to $10 on eBay. Heavy fills that wipe out most of Roosevelt’s portrait or the full reverse torch and lettering can reach $30 to $50 in uncirculated grades. The more design that is missing, the more collectors pay.

How to Identify: Look for areas where details appear soft or completely absent with a smooth, featureless surface underneath. Under 10x magnification, the affected zone should show a gradual fade from sharp detail into blankness rather than the sharp boundary you see with a clipped planchet. Check both sides of the coin. Grease fills typically hit one side only because only one die had the buildup. If both sides look weak, you may have a weak strike instead — a different error caused by insufficient press pressure. The fastest way to confirm is tilting the coin under bright light. Genuine grease fills show a smooth, even surface in the blank area, while environmental damage looks pitted or rough.

2. 2015 Dime Die Crack Error (Up to $100)

Die cracks form when the steel striking die develops stress fractures from repeated use under extreme pressure. Metal from the planchet flows into these cracks during striking, producing raised lines on the finished coin.

On 2015 dimes, die cracks commonly run from the rim through Roosevelt’s hair or across the reverse torch. Early-stage cracks appear as thin hairlines, while advanced ones can be thick and branching.

The progression matters to collectors — advanced-stage examples with dramatic lines crossing major design features bring the strongest premiums.

Value: No individual 2015 dime die crack has a verified major auction record. Minor cracks that cross non-critical areas sell for $5 to $25, depending on length and visibility. Dramatic cracks spanning the full diameter or creating unusual patterns connecting design elements can reach $50 to $100 in mint state grades. Advanced die cracks approaching the cud stage command the most interest.

How to Identify: Under a 10x loupe, look for raised lines that follow irregular paths across the coin surface. The line should cross over design elements naturally, sitting at the same level as the surrounding design rather than on top of it. Trace the crack from end to end — genuine die cracks typically run rim to rim or from a design element to the rim. Check for branching where one crack splits into smaller fractures. Post-mint scratches sit on top of the design and show a different texture under magnification. The fastest confirmation is checking whether the line is raised above the coin surface. Die cracks are always raised; scratches are always incused.

3. 2015 Dime Doubled Die Reverse FS-801 Error (Up to $100)

The 2015-P FS-801 is a Class VIII tilted hub doubled die — the hub was slightly tilted during its second impression onto the working die. Every coin struck by that die carries identical doubling on the reverse.

PCGS recognizes this variety under CoinFacts number 929339, and it holds FS-801 status in the Cherrypickers’ Guide. The Universal Rarity Scale rates it URS-5, meaning roughly 13 to 32 examples are known.

The doubling appears on “ONE DIME” and “E PLURIBUS UNUM” as thickened, notched letter serifs. This variety exists only on Philadelphia-mint coins.

Value: No verified auction record exists in Heritage or Stack’s Bowers archives as of 2026. The estimated range of $50 to $100 or more in MS65 comes from comparable modern dime doubled die sales between 2010 and 2024, cross-referenced with PCGS and NGC census data. Professional attribution by PCGS or NGC adds significant credibility and resale value. Raw, unattributed examples sell for less.

How to Identify: Use 10x to 20x magnification on the reverse and focus on “ONE DIME” first. Look for split serifs — the corners of letter tips should appear forked or notched, as if the letter gained extra width. The doubling must be raised and rounded, adding volume to the letters. Machine doubling is extremely common on 2015 dimes and looks completely different — flat, shelf-like steps that shear metal away rather than adding it. If the secondary image looks like a staircase cut into the letter, stop. That is machine doubling and it is worth nothing. Compare your coin to diagnostic images on Variety Vista’s 2015-P DDR-001 page. The fastest test is checking whether the doubling makes letters fatter or thinner. Fatter means genuine; thinner means machine doubling.

4. 2015 Dime Retained Cud Error (Up to $185)

A retained cud forms when a piece of the die’s striking surface cracks and sinks below the surrounding die face without breaking away entirely. The sunken fragment still strikes the planchet, leaving a distinctive raised, irregular blob instead of the intended design.

This differs from a full cud, where the die fragment detaches completely and leaves a blank, featureless lump on the rim. Retained cuds keep the broken piece in place, creating a subtler but still visible distortion.

The size and location determine collector interest. Larger cuds on prominent design areas bring stronger prices.

Value: GreatCollections auctioned a 2015-D Roosevelt dime graded MS64 with a retained cud on the reverse for $185 in 2016. That remains the benchmark sale for this error type on 2015 dimes. Smaller retained cuds on less prominent areas of the coin typically sell in the $30 to $80 range. Uncirculated examples with large, well-positioned cuds affecting major design elements approach or exceed $185.

How to Identify: Look for an irregular raised area on the coin that does not match any part of the normal design. The cud will typically appear near the rim and may distort adjacent letters or design features. Under magnification, you should see a clear boundary where the sunken die fragment’s edge created a step in the coin’s surface. The raised area will have a slightly different texture from the surrounding struck design. Do not confuse retained cuds with die chips, which are much smaller and produce tiny raised dots. Die chips rarely exceed the size of a pinhead, while retained cuds span several millimeters. The fastest way to confirm is checking whether the raised area disrupts the normal design flow — displaced or distorted letters around the lump indicate a retained cud.

5. 2015 Dime Feeder Finger Error (Up to $200)

The feeder finger is a mechanical arm on the coining press that positions blank planchets into the collar before striking. It is supposed to retract before the dies close, but when it malfunctions, the finger scratches across the planchet surface under full striking pressure.

These marks look like abstract scratches, but they were created during the actual minting process. That mechanical origin separates them from ordinary post-mint scratches.

The error is uncommon on modern dimes because automated presses rarely malfunction this way.

Value: A 2015-P Roosevelt dime graded MS64 with a feeder finger error on the obverse sold for $200. The source has been referenced across multiple numismatic databases. General market values range from $50 to $200, depending on how prominent the scratch pattern is and whether it crosses over important design elements like Roosevelt’s portrait. Examples where feeder marks obscure key inscriptions command the strongest premiums.

How to Identify: Look for linear scratch marks that run in parallel or semi-parallel lines across the coin’s surface. Under 10x magnification, genuine feeder finger marks show raised metal along the scratch edges, indicating the metal was displaced by pressure during striking rather than removed by abrasion. Post-mint scratches show removed metal with no raised edges — this is the critical difference. The marks should appear at consistent depth across both raised design elements and recessed fields, which would not happen with wear or handling damage. Check whether the scratch pattern has a consistent direction and spacing suggesting a mechanical arm’s movement. The fastest confirmation is looking for raised burrs along the scratch edges — metal pushed aside rather than scraped away means a minting-process error.

6. 2015 Dime Broadstrike Error (Up to $210)

A broadstrike happens when the retaining collar — the ring that defines the coin’s diameter and imparts edge reeding — is missing or fails during striking. Without the collar, the planchet spreads outward under full die pressure, producing a coin wider than normal with a smooth edge.

The full design still appears on both sides because the dies struck the planchet squarely. But the metal flowed beyond the intended boundary, creating a coin visibly too large for its denomination.

This error is uncommon on modern dimes because collar positioning is automated.

Value: A 2015-D Roosevelt dime graded MS60 with a broadstrike error sold for $210. Minor broadstrikes that barely exceed standard diameter bring less — typically $30 to $80 for examples showing only a millimeter or two of extra spread. The most valuable broadstrikes show substantial diameter increase with the full design visible on both sides. Severe broadstrikes that significantly distort the design are worth more than those with subtle expansion.

How to Identify: Measure the coin with calipers. A standard Roosevelt dime measures 17.91 mm in diameter, and any reading above that supports a broadstrike diagnosis. The edge will be smooth — no reeding — because the collar was absent during striking. Weigh the coin to confirm it matches the standard 2.27 grams, ruling out a wrong-planchet error. Compare against a normal dime side by side; the size difference should be visible to the naked eye. Do not confuse this with a dryer coin, which also has a smooth edge but is the same diameter or smaller because tumbling in a dryer compresses the rim inward. The fastest test is diameter — broadstrikes are always larger than normal, dryer coins never are.

7. 2015 Dime Misaligned Die Error (Up to $210)

A misaligned die error occurs when the obverse and reverse dies lose proper alignment during striking. The planchet gets struck normally by one die, but the opposing die hits at a rotation, causing the designs on opposite sides to sit at different angles.

On a properly struck coin, flipping it on the vertical axis shows the reverse in the same upright orientation. A rotated die error shows the reverse tilted at an angle relative to the obverse.

Collectors measure the rotation in degrees, with a 180-degree full inversion being the most valuable.

Value: A 2015-P Roosevelt dime graded MS60 with a misaligned die error sold for $210 at eBay in 2016. Minor rotations of 10 to 30 degrees are more common and typically sell for $20 to $60. Moderate rotations between 45 and 90 degrees bring $75 to $150. The value scales directly with the degree of rotation, and examples approaching full 180-degree inversion command the strongest prices.

How to Identify: Hold the coin by the top edge with the obverse facing you and Roosevelt upright. Flip the coin on its vertical axis so the reverse faces you. On a normal coin, the torch should also be upright. If the reverse design appears tilted, you have a die rotation — estimate the angle using a protractor or by visual comparison. Both sides will have full, properly struck designs, with the error appearing only in their relative alignment. Do not confuse this with a coin held at an angle; the misalignment is permanent regardless of orientation. The fastest test is the flip check — if the reverse is not upright when the obverse is, you have a misaligned die.

8. 2015 Dime Struck Through Foreign Object Error (Up to $210)

A struck-through error occurs when a foreign object — wire, cloth fiber, staple, or other debris — gets trapped between the die and planchet during striking. The die presses the object into the coin’s surface, leaving an impression of whatever was caught in the press.

Sometimes the object stays embedded afterward, creating a retained struck-through. Other times it falls away, leaving only the indentation.

The shape and clarity of the impression determine value — a clear cloth weave pattern is worth more than an amorphous dent.

Value: Heritage Auctions sold a 2015-P Roosevelt dime graded MS63 with a struck-through error on the obverse for $210 in 2018. General market values range from $30 to $210, depending on how dramatic and identifiable the foreign object’s impression is. Retained struck-throughs where the material remains embedded typically bring higher prices. Larger impressions affecting prominent design areas command the strongest premiums.

How to Identify: Look for an indentation or depression in the coin’s surface that does not match any part of the intended design. The impression may show a recognizable pattern — cloth weave, wire shape, or other texture from the foreign object. Under magnification, the surrounding metal should show displacement around the impression, with the coin’s design disrupted in the affected area. The impression will be incused into the struck surface rather than sitting on top. Check that design elements around the impression are properly struck, confirming the coin went through normal minting. Post-mint contact marks are shallower and do not disrupt the surrounding design. The fastest confirmation is whether the impression cuts into the struck design or sits on top — into means genuine, on top means post-mint.

9. 2015 Dime Improperly Annealed Error (Up to $310)

Annealing is the controlled heating and cooling of metal strips before they are punched into planchets — the process softens the metal so it can accept the die’s design during striking. When the temperature or timing goes wrong, the finished coin comes out with unusual coloring.

Improperly annealed 2015 dimes can appear dark, mottled, purple, yellowish, or brown. The key difference from environmental damage is that the coin retains metallic mint luster beneath the discoloration.

This is a high-fraud-risk category. Sellers routinely pass off chemically damaged coins as improperly annealed.

Value: GreatCollections auctioned a 2015-D Roosevelt dime graded MS65 with an improper annealing error for $310 in 2017. That sale remains the strongest reference point for this error on 2015 dimes. Lower-grade examples or those with less dramatic color variation sell in the $50 to $150 range. The combination of unusual coloring with full mint luster and a high grade pushes values toward $300 and above.

How to Identify: The coin will appear dark, mottled, or discolored compared to a normal dime, but it must retain a glossy, metallic mint luster visible beneath the abnormal surface. This is the critical authentication point. Environmentally damaged coins — those exposed to chemicals, soil, or corrosive liquids — show dull, matte, pitted surfaces with no luster at any angle. Weigh the coin to confirm standard tolerance of 2.20 to 2.35 grams. Use a strong light source and tilt the coin to check for underlying metallic sheen. If the surface is uniformly dull with no luster, it is almost certainly post-mint damage. The fastest test is the luster check — no luster means no premium.

10. 2015 Dime Lamination Error (Up to $315)

Lamination errors happen when contaminants trapped in the metal strip during manufacturing create weak spots in the bond between the coin’s clad layers. If the bonding fails at any of those weak points, the outer copper-nickel layer can crack, lift, or peel away from the copper core beneath.

The result is a coin with a visible flap, bubble, or missing patch where the surface layer has separated. This differs from a missing clad layer, which is a pre-bonding absence — lamination is a post-bonding separation.

Value: Heritage Auctions sold a 2015-D Roosevelt dime graded MS63 with a lamination error for $315 in 2016. That is the highest confirmed sale for this error on a 2015 dime. Smaller lamination flaps or bubbles that do not expose much of the underlying core typically sell in the $40 to $120 range. Larger peels revealing substantial copper core area, especially on the obverse, bring prices closer to the $315 benchmark.

How to Identify: Look for a raised flap, bubble, or crack in the coin’s surface where the outer clad layer appears to be separating from the core. The affected area may show copper color beneath the nickel surface. Under magnification, you should see a clear delamination line where the layers have split. The surrounding struck design should be normal, confirming this happened during or before the minting process rather than from post-mint abuse. Weigh the coin — it should be at or slightly below the standard 2.27 grams if material has peeled away. Do not confuse lamination with plating bubbles on copper-plated zinc cents, which look similar but have different composition. The fastest confirmation is copper visible through a split in the nickel surface layer.

11. 2015 Dime Missing Clad Layer Error (Up to $415)

Roosevelt dimes are struck from a three-layer sandwich: a pure copper core bonded between two outer layers of 75% copper and 25% nickel. When one or both outer layers fail to bond during strip manufacturing, the planchet gets punched and struck without full cladding.

The visual result is dramatic — one face appears copper-red instead of the normal silvery finish, because the exposed core is visible. The thinner planchet also cannot fill the die completely, so design details on the affected side often appear weak.

Value: Heritage Auctions sold a 2015-P Roosevelt dime graded MS60 with a missing clad layer for $415 in 2017. That remains the top recorded sale for this error on 2015 dimes. Single-side missing clad examples generally trade in the $150 to $300 range, depending on grade and design completeness on the affected side. Dual missing clad errors — both faces showing copper — are extremely rare and can exceed $500.

How to Identify: One side of the coin will appear copper-red instead of silver. This alone is not enough to confirm the error — weigh the coin on a scale accurate to 0.01 grams. A single missing clad layer reads 1.80 to 1.95 grams, well below the standard 2.27 grams. A dual missing clad reads 1.50 to 1.65 grams. If the coin looks copper but weighs 2.27 grams, it is environmental damage and is worth face value. Check the edge: a genuine missing clad will show copper on the affected side while the intact side retains normal appearance. Design details on the copper side may appear weak because the thinner planchet could not fully fill the die. The fastest and most reliable test is the scale — weight below 2.0 grams confirms the error.

12. 2015 Dime Off-Center Strike Error (Up to $430)

An off-center strike occurs when the planchet is not fully seated in the collar before the dies come together. The die hits the planchet away from center, producing a coin with a blank crescent of unstruck metal on one side and the design shifted to the opposite edge.

The percentage of off-center directly determines value. A 50% shift — half blank, half design — is the most dramatic and collectible variety, but the date must remain visible for top dollar.

Value: Heritage Auctions sold a 2015-P Roosevelt dime graded MS60 with an off-center strike for $430 in 2018 — the highest confirmed sale for any 2015 dime error. Value scales with shift percentage: 5 to 15% brings $10 to $30, 15 to 30% brings $30 to $80, and 30 to 60% with a visible date reaches $100 to $430. Coins with no readable date drop to $10 to $25 regardless of appearance.

How to Identify: The blank crescent of unstruck metal is the defining feature. Hold the coin next to a normally struck dime to gauge the shift percentage, and measure the blank area with calipers if precision matters. The rim will be present only on the struck portion and absent from the unstruck crescent — this asymmetric rim is a key diagnostic. Check that both obverse and reverse are shifted in the same direction by the same amount. If only one side appears off-center while the other looks normal, you have a misaligned die error, not a true off-center strike. Verify the date and mint mark are visible on the struck portion, as this is essential for authentication and maximizing value. The fastest confirmation is the blank crescent combined with the one-sided rim.
