2013 Roosevelt Dime Errors: Value Guide & Rare Varieties
2013 Roosevelt Dime error value guide: Missing clad layer worth $100–$300+, broadstrikes, off-center strikes, and doubled die varieties. Weight tests, diagnostics, and auction records.
Most 2013 Roosevelt dimes are worth face value (10¢), but a genuine missing clad layer error fetches $100–$300+ — and a dual missing clad can exceed $1,000.
- 💰 Missing clad layer (copper-colored & underweight): $100–$300+
- 💰 Off-center strike (50%+ with full date visible): $50–$100
- 💰 2013-D Doubled Die Reverse (Ken Potter attribution): $10–$30
- 💰 MS-68 Full Bands (condition rarity): $336 auction record
- 💰 2013-S Silver Proof: $20–$60
⚠️ Critical trap: A copper-colored 2013 dime that weighs the standard 2.27g is environmental damage — not a mint error. The weight test is the only reliable confirmation.

Check your coin for valuable errors and varieties
Values shown are typical retail estimates as of 2026-01.
Error coin values vary significantly based on grade, eye appeal, and current market conditions.
Professional authentication (PCGS/NGC) is recommended for high-value errors, especially missing clad layer coins.
Machine Doubling (flat, shelf-like steps) is NOT a valuable doubled die variety and carries zero numismatic premium.
The weight test using a digital scale (0.01g precision) is the definitive method for confirming or ruling out missing clad layer errors.
Coins that appear copper-colored but weigh the standard 2.27g are environmentally damaged (PMD), not mint errors.
Repunched Mint Marks (RPMs) are impossible on 2013 dimes. Mint marks have been part of the master hub since the early 1990s.
Submitting a 2013 dime for professional grading ($30–$50 cost) is typically only financially viable for confirmed major errors or coins likely to grade MS68 Full Bands or higher.
The single-squeeze hubbing process used by 2013 eliminates dramatic doubled dies. Modern doubling is subtle Class VIII (tilted hub) type requiring careful comparison to known die markers.
Pick up a 2013 Roosevelt dime and it looks completely ordinary. But a tiny fraction of the 2.1 billion struck that year escaped the U.S. Mint with dramatic defects — one side blazing copper-red from a missing outer layer, designs punched completely off-center, and subtle die varieties documented only by specialist researchers. This guide tells you exactly what to look for, how to test it with a $10 digital scale, and what it's worth in today's market.

2013 Roosevelt Dime: Specs, Mintage & Values by Mint
Before hunting errors, you need to know what a normal 2013 dime looks like — and what the standard versions are worth. Any deviation from these specs is a diagnostic signal.
Technical Specifications
| Feature | Clad Business Strike (P/D) | Silver Proof (S) |
|---|---|---|
| Composition | 75% Cu / 25% Ni clad over pure Cu core (91.67% Cu, 8.33% Ni total) | 90% Ag, 10% Cu |
| Weight | 2.27g (± 0.097g tolerance) | 2.50g (± 0.10g tolerance) |
| Diameter | 17.9 mm | 17.9 mm |
| Thickness | 1.35 mm | 1.35 mm |
| Edge | Reeded — 118 reeds | Reeded — 118 reeds |
| Designer | John R. Sinnock (obverse portrait of FDR; reverse torch, olive & oak branch) | |
Mintage Summary
| Mint | Strike Type | Mintage |
|---|---|---|
| Philadelphia (P) | Circulation — Clad | 1,086,500,000 |
| Denver (D) | Circulation — Clad | 1,025,500,000 |
| San Francisco (S) | Clad Proof | 856,953 |
| San Francisco (S) | Silver Proof (90% Ag) | 467,691 |
Left: clad dime edge (copper stripe between silver layers). Center: silver proof (uniform white). Right: broadstrike (completely smooth, no reeds).
Philadelphia (P) Values
Circulated 2013-P dimes are worth face value — 10¢. Uncirculated examples carry a minimal premium of $0.10–$1.00 unless they reach the condition rarity threshold of MS-68 Full Bands. With 1,086,500,000 struck, no circulated P-mint coin carries any premium. Value depends entirely on discovering an error or achieving gem condition. Check for the confirmed DDO variety and missing clad errors.
Denver (D) Values
Circulated 2013-D: face value. Uncirculated: $0.10–$1.00. Denver presses generally produced slightly sharper strikes than Philadelphia in 2013, giving MS-68 Full Bands specimens a marginally better chance. A 2013-D MS-68 FB sold for $336 at auction — the top of the market for this date. Check D-mint coins for the confirmed DDR variety documented by Ken Potter.
San Francisco Clad Proof (S) Values
The 2013-S clad Proof is worth $3–$8. Mintage of 856,953 means these are readily available in the secondary market. San Francisco's stringent quality control makes mint errors extremely unlikely on proof issues. Value depends on grade certification — PR-69 DCAM vs. PR-70 DCAM.
San Francisco Silver Proof (S) Values
The 2013-S Silver Proof (90% silver, 467,691 mintage) is worth $20–$60 depending on certified grade. It weighs 2.50g versus 2.27g for clad — a quick identification test if found loose. These have maintained value better than many series years due to the relatively lower mintage. PR-69 and PR-70 grades are common since coins go from the Mint directly to collectors in protective packaging. Do NOT clean this coin.

2013 Roosevelt Dime Quick Checks: Do You Have Something Valuable?
Work through these in order. Each check takes under two minutes with a digital scale (0.01g precision) and a 10x loupe magnifier.
Check 1: Missing Clad Layer — Highest-Value Find
Both sides of the coin. One or both sides will appear deep copper-red instead of the normal silver-colored surface. The copper side often shows weakly struck, mushy design details.
Copper color AND underweight. Weigh on a digital scale: single missing layer = approximately 1.80–1.95g. Both layers missing (pure copper core only) = approximately 1.40–1.50g. Standard weight is 2.27g.
A copper-colored coin that weighs 2.27g is environmental damage from acid, soil burial, or heat — not an error. It is physically impossible to lose a metal layer and retain the full weight. The scale does not lie.
Check 2: Broadstrike (Collar Failure)
The diameter and edge of the coin. A broadstrike is noticeably wider than the standard 17.9mm. The design spreads outward with no defined rim because the collar die failed to contain the metal.
Diameter exceeds 17.9mm (measure with digital calipers) AND the edge is completely smooth with zero reeding. If any reeds are present, it is NOT a broadstrike.
A "dryer coin" has a thick, mushroomed rim and a smaller diameter — the opposite of a broadstrike. A spooned coin has rims intentionally manipulated. Any coin with reeding cannot be a broadstrike.
Check 3: Off-Center Strike
The overall design alignment. Part of the coin will be blank (completely unstruck) in a crescent shape where the planchet was not fully seated between the dies during striking.
A smooth, lustrous blank crescent area on the coin. The premium target: 50%+ off-center with the full date "2013" still visible in the struck portion. Modern off-centers are scarcer because press sensors eject most misfed planchets.
Post-mint damage creating flat spots, dents, or bent edges is not an off-center strike. A genuine off-center has smooth, mint-quality unstruck metal in the blank area — no rough edges, pitting, or scratches.
Check 4: Doubled Die Reverse — D-Mint Coins Only
The reverse (back) of D-mint coins only. Focus on the torch design and the lettering "ONE DIME." Use a 10x loupe magnifier.
Class VIII (tilted hub) doubling: rounded, bulbous extra thickness on the torch elements and "ONE DIME" lettering. Not a sharp second image — a 3D thickening. Must match documented die markers for confirmed attribution.
Machine doubling shows flat, staircase-step shelving on one side of letter edges — completely worthless. Weak strikes from worn dies show mushy details, not doubling. Die deterioration produces ghosting around elements — also worthless.
Check 5: Doubled Die Obverse — P-Mint Coins Only
The obverse (front) of P-mint coins only. Focus on "IN GOD WE TRUST" and the date "2013." Use a 10x loupe magnifier.
Extra rounded thickness on letter serifs in "IN GOD WE TRUST" and date numerals. Listed in the Wexler Doubled Die Files as "2013-P 10¢ Complete." Specific die markers (unique scratches or gouges on the die) must be matched for positive attribution.
Machine doubling (flat shelf-like steps) is the dominant false positive — worthless. Also disregard online listings citing "Jefferson's nose" or "doubled door frames" — those describe Jefferson Nickel and quarter varieties, not Roosevelt Dimes.
Trap Alert: Machine Doubling — The #1 False Alarm on 2013 Dimes
Any lettering — "LIBERTY," "IN GOD WE TRUST," the date. Extremely common on high-volume 2013 press runs.
Nothing — this is a trap. Machine doubling is a quality control slip where a loose die shifts upon retraction. It carries zero numismatic premium.
Machine doubling looks like a staircase — flat, 2D shelf-like steps on one side of letters, as if metal was sheared sideways. True doubled dies show rounded, 3D extra thickness. If you describe it as "pushed sideways," it is machine doubling.

2013 Roosevelt Dime Errors Worth Real Money: Complete Identification Guides
These are the errors with confirmed numismatic value. Each guide includes the origin, exact diagnostic steps, what to avoid confusing it with, and current market values.
2013 Missing Clad Layer Error
Normal silver dime (left) vs. missing clad layer error with copper-red obverse (right).
Origin & Background
The dime's clad structure is a three-layer sandwich: two outer layers of 75% copper / 25% nickel (silver in color) bonded to a pure copper core. During strip production, if the bond between one clad layer and the copper core fails, that entire layer can separate before or during striking. The result is a coin that is brilliantly silver on one side and deep copper-red on the other. This is the premier error type for the Roosevelt dime series and the highest-value find for 2013.
How to Identify
- One side appears deep copper-red; the opposite side appears normal silver.
- The copper side typically shows weakly struck, mushy design details — the thinner planchet (missing a layer's mass) does not fill the die cavity completely.
- Weigh it on a digital scale with 0.01g precision. Single missing clad layer: approximately 1.80–1.95g. Both layers missing (pure copper core only): approximately 1.40–1.50g. Standard 2013 dime: 2.27g.
- The weight test is absolute. No legitimate missing-clad coin can weigh 2.27g.
Scale showing ~1.90g for a missing clad error vs. 2.27g for a standard dime.
False Positives to Avoid
The most common false positive is a coin that has turned copper-colored from environmental damage — acid exposure, soil burial, fire, or prolonged heat. These coins retain the full 2.27g weight because no metal is missing; only the surface has been chemically altered. Additional tells: pitting, rough or porous texture, and a "thuddy" non-ringing sound when dropped (heat destroys the metal's crystalline structure). A genuine missing-clad error retains original mint luster on the exposed copper surface.
Market Values
- Single missing clad layer: $100–$300
- Dual missing clad (copper core only): $1,000+
Auction Record & Authentication
Confirmed missing-clad Roosevelt dimes typically realize $100–$300 at major auction houses. Professional authentication by PCGS or NGC is strongly recommended before selling — buyers at these price levels expect slabbed coins. See PCGS's reference: Missing-Clad Layer Mint Error Coins.
2013 Broadstrike Error (No-Collar Error)
Normal 17.9mm dime with reeded edge (left) vs. broadstrike with spread design and smooth edge (right).
Origin & Background
During striking, the collar die surrounds the planchet, contains the metal flow, and imprints the reeded edge. If the collar fails to deploy, the metal spreads outward unconstrained. The coin becomes wider than normal with no defined rim and a completely smooth edge. The design is typically present but spread outward.
How to Identify
- Measure the diameter with digital calipers — must exceed 17.9mm.
- Examine the edge: it must be completely smooth with zero reeding. Even one or two reeds disqualifies a broadstrike claim.
- The design spreads outward with no rim to contain it.
- The full obverse and reverse design should be present, just wider than normal.
False Positives to Avoid
A dryer coin is the most common confusion — it has an extremely thick, mushroomed, rounded rim with a smaller diameter from being trapped in a commercial dryer. That is post-mint damage (PMD), the opposite of a broadstrike. A spooned coin has rims intentionally altered by pressing with a spoon — also PMD. Any reeding whatsoever on the edge rules out a broadstrike entirely.
Market Values
- 2013 Broadstrike: $10–$20
2013 Off-Center Strike Error
50%+ off-center 2013 dime: struck design half (with date) and smooth blank crescent.
Origin & Background
When a planchet lands partially off the anvil die during feeding, only the portion above the die gets struck. The rest remains blank. Modern presses have sensors to detect and eject misfed planchets before they leave the press chamber, making off-center modern dimes scarcer than vintage examples. This higher escape difficulty is reflected in values that can exceed vintage off-center coins on a percentage basis.
How to Identify
- A crescent-shaped blank area on the coin with smooth, lustrous, mint-quality metal.
- Estimate the percentage off-center: roughly what fraction of the coin is unstruck?
- Check whether the full date "2013" and mint mark are visible in the struck portion. Date visibility dramatically increases value.
- The 50%+ off-center with complete date is the premium target for 2013.
False Positives to Avoid
Post-mint damage creating flat spots, bent areas, or irregular surfaces is not an off-center strike. A genuine off-center has smooth, lustrous, mint-quality metal in the blank crescent — no rough edges, pitting, scratches, or discoloration. If the blank area is rough or damaged, it is PMD.
Market Values
- ~10% off-center: $5–$10
- 50%+ off-center with full date "2013" visible: $50–$100
2013-D Doubled Die Reverse (DDR) — Ken Potter / Allen Darrow Attribution
2013-D DDR: bulbous extra thickness on ONE DIME lettering (right) vs. sharp normal (left).
Origin & Background
By 2013, the U.S. Mint had fully transitioned to single-squeeze hubbing — the master hub is pressed into the working die in one continuous high-pressure operation. This eliminates the dramatic misalignment doubling of the mid-20th century but introduces Class VIII (tilted hub) doubling: if the hub snaps slightly out of angular alignment before fully seating, the design smears or thickens. This specific 2013-D variety was documented by researcher Ken Potter from a submission by collector Allen Darrow. The Roosevelt dime series is notably under-researched compared to Lincoln cents, so new varieties continue to emerge.
How to Identify
- D-mint coins only.
- Use a 10x loupe magnifier on the reverse (back).
- Focus on the torch design and "ONE DIME" lettering.
- Look for rounded, bulbous extra thickness on letter serifs and torch horizontal elements — not a sharp second image.
- Compare directly to a known normal 2013-D reverse specimen to make the thickening visible.
- Die markers are required for positive attribution: unique scratches or gouges on the die must be matched. Without markers, proving the variety is very difficult.
False Positives to Avoid
Machine doubling (flat, shelf-like staircase steps on letter edges) is the most pervasive false positive and carries zero numismatic value. Weak strikes from exhausted dies show mushy, incomplete detail — not doubling. Die deterioration doubling (DDD) produces a hazy ghosting around elements — also worthless. True Class VIII doubling is rounded and three-dimensional; machine doubling is flat and two-dimensional.
Market Values
- Verified 2013-D DDR: $10–$30 in the specialist market. Not listed in the standard Red Book, limiting broader commercial demand.
Variety Reference
Consult the Wexler Doubled Die Files — Roosevelt 10¢ for documented die markers and comparison images necessary for attribution.
2013-P Doubled Die Obverse (DDO) — Wexler Doubled Die Files
2013-P DDO: rounded extra thickness on IN GOD WE TRUST (right) vs. sharp normal (left).
Origin & Background
Varieties for the 2013-P are listed in the Wexler Doubled Die Files as "2013-P 10¢ Complete." Like the 2013-D DDR, these exhibit Class VIII tilted hub doubling from the single-squeeze process, but on the obverse (front) of P-mint coins. The Roosevelt dime series is one of the least-studied major U.S. series, meaning these varieties have low market values currently but may appreciate as research catches up. Market pricing for this specific variety is not yet established in major catalogs.
How to Identify
- P-mint coins only.
- Use a 10x loupe magnifier on the obverse (front).
- Focus on "IN GOD WE TRUST" and the date "2013."
- Look for rounded, bulbous extra thickness on letter serifs — particularly noticeable on letters with open bowl areas (G, O, D).
- Die markers are essential for attribution. Specific scratches or gouges unique to this die must be identified and matched. Without markers, confirming the variety is extremely difficult for a non-specialist.
False Positives to Avoid
Machine doubling is dominant and worthless. Also disregard any online listings referencing "Jefferson's nose" or "doubled door frames" in context with 2013 dimes — those descriptions apply to the 2013 Jefferson Nickel and Washington quarter varieties, respectively. The Roosevelt dime features no Jefferson portrait and no building architecture. Cross-contaminated descriptions on high-volume resale platforms are common.
Market Values
- Verified 2013-P DDO: Market value is under active research by variety specialists. Contact variety coin dealers directly. This variety is listed in the Wexler Doubled Die Files but has not yet established pricing in major commercial catalogs.
2013 Roosevelt Dime Value Traps: What to Rule Out First
The majority of "error" coins brought to dealers are actually these three things. Rule them out before getting excited.
⚠️ Machine Doubling — The #1 False Alarm
Letters on the coin appear doubled or shadowed — "IN GOD WE TRUST," "LIBERTY," or the date look like they have a ghost image sitting next to the primary.
High-speed presses have dies that can shift slightly upon retraction immediately after striking. The metal gets sheared sideways by the retracting die face, creating a flat secondary image. This is a quality control slip, not a die variety.
- Under 10x magnification, machine doubling looks like a staircase — flat, shelf-like steps on one side of letters, as if pushed sideways.
- True doubled dies (Class VIII) show rounded, 3D extra thickness. Machine doubling is flat and 2D.
- Machine doubling is always on the same side of letters (the side the die retracted toward). Class VIII thickening is on all sides of a serif.
Value: Face value only.
⚠️ Dryer Coin & Spooned Rim — Not a Broadstrike
The rim is extremely thick, tall, and rounded. The coin may fit inside a penny wrapper because it is actually smaller in diameter. The clad layer may look dull or partially separated.
The coin was trapped between the rotating drum and housing of a commercial dryer. Prolonged rolling friction and heat mushroom the rim inward and gradually shrink the diameter while dulling the surface luster.
- A genuine broadstrike is larger than 17.9mm with a smooth edge. A dryer coin is smaller with a thick rim — the direct opposite.
- Drop the coin on a hard surface: heat damage destroys the internal crystal structure, making it sound "thuddy" instead of ringing. A genuine error will still ring.
- Heat discoloration or uneven luster further confirms dryer damage.
Value: Face value only.
⚠️ Copper-Colored Coin That Weighs 2.27g — PMD, Not a Missing Clad
The coin surface appears reddish-copper instead of silver. You assume this is a missing clad layer error worth $100+.
Acid exposure, soil burial, fire, or prolonged heat can chemically alter the nickel-copper surface layer — making it look copper while leaving all the metal physically in place.
- Weigh it. If the coin registers 2.27g (or within tolerance), the clad layer is still there. A single missing layer must produce a weight of approximately 1.80–1.95g. This is non-negotiable physics.
- Environmental damage also produces pitting, rough or porous surface texture, and dull luster. Genuine missing-clad errors retain original mint luster on the exposed copper surface.
Value: Face value only.
Machine doubling (left, flat staircase steps) vs. true Class VIII doubled die (right, rounded 3D thickness).
Dryer coin (left, thick rim, smaller diameter) vs. broadstrike (right, wider, smooth edge).
⚠️ Repunched Mint Marks Are Impossible on 2013 Dimes
Repunched Mint Marks (RPMs) — where a "D" is punched over a "D" — cannot exist on any 2013 dime. The U.S. Mint integrated the mint mark into the master hub in the early 1990s. By 2013, it is part of the die from the start and cannot be double-punched. Any apparent RPM is machine doubling or a die chip — neither carries numismatic value.
2013 Roosevelt Dime Grading: How Grade Drives Value
For standard 2013 dimes with no error, condition is the only value driver. The Sheldon 70-point scale applies: higher grade = higher value. But the jumps are dramatic.
- Circulated (G-4 to AU-55): Face value (10¢). Wear is visible on Roosevelt's cheekbone and temple, and on the torch bands on the reverse.
- Uncirculated MS-60 to MS-67: $0.10–$1.00. Common and abundant from mint sets and rolls. Not worth certifying.
- Proof PR-69 DCAM (S): $3–$8 (clad) | $20–$60 (silver). The Deep Cameo (DCAM) designation requires frosty design devices against mirror-like fields.
The Full Bands (FB) Designation — The Key to Condition Value
Full Bands (FB): both pairs of horizontal torch bands must be fully separated with no bridging metal.
The Full Bands (FB) designation (PCGS) — also called Full Torch (FT) by NGC — requires both the upper and lower pair of horizontal bands on the reverse torch to be completely separated, with no metal bridging between them and no impact marks obscuring the separation. As dies wear through millions of strikes, the fine band detail is the first feature to degrade.
A standard 2013 MS-65 dime is worth face value. A 2013-D MS-68 FB is a condition rarity with an auction record of $336. This dramatic jump — from 10¢ to $336 — illustrates how powerful the FB designation is on modern clad Roosevelt dimes.
Grading cost reality: Professional certification costs approximately $30–$50 per coin including shipping. Submitting a 2013 dime is only financially worthwhile if you are confident it will grade MS-68 Full Bands or higher. Most roll-picked uncirculated coins grade MS-64 to MS-66 — far below the threshold where grading pays off.
2013 Roosevelt Dime Authentication: When to Get Your Coin Certified
Professional certification by PCGS (Professional Coin Grading Service) or NGC (Numismatic Guaranty Company) is the industry standard for high-value coins. It protects you from fraud, maximizes resale value, and provides independent validation. But it isn't always financially worthwhile.
Submit for Certification When:
- Confirmed missing clad layer (coin weighs 1.80–1.95g or less): Always certify. Authenticated errors sell for $100–$1,000+ — well above the $30–$50 submission cost. Buyers at this level expect a certified slab.
- Significant off-center strike (40%+ with full date): Expected value of $50–$100 clears the submission cost with margin.
- Potential MS-68 Full Bands: Only if you are an experienced grader with high confidence in the grade. Submitting an MS-65 coin is a guaranteed financial loss.
- 2013-S Silver Proof targeting PR-70 DCAM: Worth submitting if acquired from the Mint in pristine original packaging.
Do NOT Submit:
- Any circulated 2013 dime — certification cost far exceeds any possible return.
- Minor errors such as grease strikes or small clips — typically worth $1–$5.
- DDR or DDO varieties unless you have a confirmed buyer willing to pay specialist prices.
💡 Tip: Photograph Before Handling
If you believe you have a valuable error, photograph it immediately under good lighting before doing anything else. Handle only by the edges. Do not clean it under any circumstances — cleaning permanently destroys numismatic value and is detectable by graders.

2013 Roosevelt Dime Errors: Frequently Asked Questions
Is my 2013 dime worth anything?
Almost certainly face value (10¢) unless it has a confirmed mint error or achieves extreme gem condition. With over 2.1 billion struck for circulation, the 2013 dime is one of the most common modern coins in existence. The exceptions with real value: a missing clad layer ($100–$300+), a major off-center strike ($50–$100), an MS-68 Full Bands specimen ($336 auction record), or the 2013-S Silver Proof ($20–$60).
My 2013 dime looks copper-colored. Is it an error?
Weigh it immediately on a digital scale. If it weighs 2.27g, it is not a mint error — the clad layer is still present but has been chemically altered by environmental exposure (acid, soil burial, heat). A genuine single missing clad layer must weigh approximately 1.80–1.95g. This is a hard physical constraint: you cannot lose a layer of metal and retain the full weight of the coin.
What does "Full Bands" mean and why does an MS-68 FB sell for $336?
"Full Bands" (FB) requires both pairs of horizontal bands on the reverse torch to be fully separated with no metal bridging between them. As dies wear from striking hundreds of millions of coins, this fine detail degrades first. Finding a 2013 dime where every band is perfectly separated at MS-68 grade is genuinely rare — hence the $336 auction record. A standard MS-65 example without the designation is worth face value.
Why can't 2013 dimes have Repunched Mint Marks?
Repunched Mint Marks require the mint mark to be hand-punched into individual working dies — a practice the U.S. Mint discontinued in the early 1990s. By 2013, the mint mark is built into the master hub and transfers to every working die as one unit. It is mechanically impossible to produce an RPM under this system. What you see is machine doubling or a die chip — both worthless.
Is machine doubling valuable?
No — zero numismatic premium. Machine doubling (also called mechanical doubling or strike doubling) occurs when a die shifts upon retraction, shearing metal sideways. It looks like flat, staircase-like steps on one side of letters. True Class VIII doubled dies show rounded, three-dimensional extra thickness on all sides of letter serifs. If you can describe the doubling as "pushed sideways," it is machine doubling and carries no value above face value.
Is the 2013-S Silver Proof worth keeping?
Yes, if you have it in original protective packaging. With 467,691 mintage (lower than most years in the series), it trades at $20–$60 depending on certified grade. Its 90% silver composition (weighing 2.50g vs. 2.27g for clad) gives it inherent metal value beyond the numismatic premium. These have held value better than many other Roosevelt dime years. Never clean it — cleaning destroys value.
Why doesn't the 2013 dime have dramatic doubled dies like the 1955 Lincoln cent?
The famous 1955 doubled die occurred because dies were pressed from the master hub multiple times ("multiple-squeeze" hubbing). If the die shifted between pressings, a dramatic double image resulted. By 2013, the Mint uses "single-squeeze" hubbing — one continuous high-pressure impression — making rotational misalignment between hub presses impossible. Any 2013 doubling is the subtle Class VIII (tilted hub) type: slight thickening, not a clear offset second image.
How do I tell a clad proof from a silver proof?
The fastest method: weigh the coin. A 2013-S clad proof weighs 2.27g. A 2013-S silver proof weighs 2.50g. You can also examine the edge: the clad proof shows a visible copper stripe between two silver layers; the silver proof has a uniform white edge with no copper stripe visible. The silver proof also has a slightly brighter white luster.

A note on images: To help illustrate coin diagnostics and rare varieties — especially complex errors that are difficult to describe in text alone — this guide uses AI-generated images. All written values, diagnostics, and variety attributions have been manually reviewed against the cited sources above. 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. Numismatic knowledge is a community effort, and your input helps us build a more accurate resource for everyone.
