Check your coin for valuable errors and varieties
Values shown are typical retail estimates as of 2025-01, based on verified auction results and dealer listings.
A circulated 1989 dime with no errors is worth face value (10¢).
Error coin values vary significantly based on grade, eye appeal, and market conditions.
Professional authentication (PCGS/NGC/ANACS) is recommended for any coin suspected of being a valuable error.
Machine Doubling (flat, shelf-like smearing) is NOT a valuable error — it is the most common misidentification for 1989 dimes.
Environmental damage (brown or coppery discoloration at normal 2.27g weight) is NOT a Missing Clad Layer error. The weight test is mandatory.
No verified 1989 No S Roosevelt Dime Proof exists. This is a debunked myth.
The 1989 series was one of the last years with hand-punched mint marks; starting in 1990, mint marks were placed on the master die.
The 1989 Roosevelt dime looks like pocket change — but 1989 was one of the last years the U.S. Mint hand-punched mint marks into individual working dies, making this series the final frontier for Repunched Mint Mark (RPM) varieties. Over 2.1 billion were struck under maximum production pressure, and that stress created genuine planchet and striking errors worth real money.

1989 Roosevelt Dime Quick Checks: What to Look For First
1989 Roosevelt Dime Quick Checks: What to Look For First
Work through these checks in priority order. You will need a digital gram scale (0.01g precision) and a 10x loupe (magnifying glass) for several of them.
Check #1 — Missing Clad Layer (The Copper Dime)
Both sides of the coin. One side will show a distinctly different copper-red color while the other remains the normal silver color.
Copper-red side with mint luster — a shiny, struck surface (not rough or pitted). The coin must also weigh 1.94–2.00g on a digital scale. The missing cupronickel layer accounts for roughly 15% of the coin's total mass.
A brown or reddish dime weighing 2.27g is environmental damage — acid exposure leaches the nickel, turning the surface coppery. Damaged coins have pitted, matte surfaces with zero luster.
Check #2 — 1989-P Doubled Die Obverse DDO-001 (P mint only)
The obverse (front) inscription LIBERTY — specifically the letters B, E, and R. Use a 10x loupe.
Medium extra thickness on the LIBERTY letters directed toward the rim. Letters appear wider or bloated; the space between them is reduced. This is Class II Distorted Hub Doubling — no clean split, just a swollen, puffy look.
Machine Doubling (MD) — flat, shelf-like extensions that disappear when you tilt the coin. If it looks smeared or pushed, it has no numismatic value.
Check #3 — Off-Center Strike
The overall coin shape and design placement. Look for a crescent-shaped area of blank metal where no design was struck.
Design bleeds off the edge with a visible blank crescent. The date (1989) must be visible for maximum value. More off-center equals higher value — 50%+ with the date visible is most desirable.
A misaligned die strike shows a slight shift but the full design remains within the rim. Post-mint damage (bent or filed coins) lacks the characteristic crescent-shaped blank area.
Check #4 — 1989-D Repunched Mint Mark RPM (D mint only)
The D mint mark on the obverse above the date. 1989 was one of the final years with hand-punched mint marks before the 1990 changeover to master-die incorporation.
A secondary D at full relief — a distinct notch or tail on the main D serif, or a secondary vertical bar inside the curve of the D. Both images must be equally raised.
Machine doubling on the mint mark — which shows a flat, shelf-like extension at reduced relief, not a fully raised second impression.
Check #5 — Broadstrike (Missing Collar)
The edge and overall diameter. Compare side-by-side with a normal dime.
Coin is visibly wider than 17.90mm with a smooth, tapered edge — no reeding. Full design is present on both sides. The metal spread outward because the collar die failed to constrain it.
A dryer coin (tumbled in a clothes dryer) — which is smaller in diameter with a thick, upset rim, the opposite of a broadstrike. Worn reeding from circulation keeps normal diameter.
Check #6 — 1989-D Full Bands FB (D mint, uncirculated only)
Reverse (back) torch — the horizontal bands crossing it under 10x magnification.
Both sets of horizontal bands completely separated and distinct with no merging at any point. Requires an uncirculated coin with an exceptional, sharp strike. Professional grading by PCGS or NGC is needed to receive the official FB designation.
Partially separated bands that merge at any point do not qualify. Most 1989-D dimes fail because dies were overused during the high-volume run. This is a strike quality designation, not a mint error.
⚠️ Trap Checks — Most 1989 Dimes Fail Here
Machine Doubling — NOT Valuable (Most Common Misidentification)
The date, LIBERTY, and IN GOD WE TRUST on the obverse.
Flat, shelf-like smearing beside letters or numbers that can look like doubling. This appears on the vast majority of 1989 dimes questioned by collectors and carries zero numismatic value.
Tilt the coin under a light. Machine Doubling disappears or flattens at different angles. True Doubled Dies show rounded thickening that remains visible from all angles. See full Traps section →
Environmental Damage — NOT a Clad Error
Both sides — any brown, reddish, or gritty discoloration.
A reddish or brown dime that looks copper-colored. Acid exposure from soil, beverages, or chemicals leaches the nickel, turning the surface coppery.
Weigh the coin. If it reads 2.27g, it is environmental damage — not a Missing Clad Layer. Genuine errors have mint luster on the copper side and weigh only 1.94–2.00g. See full Traps section →

1989 Roosevelt Dime Errors Worth Real Money
These are the verified errors and varieties that command genuine market premiums. Each entry includes how to identify it, what to avoid confusing it with, and verified market values.
1989 Roosevelt Dime Missing Clad Layer — The Copper Dime
Normal silver dime (left) vs. Missing Clad Layer error showing the distinctive copper-red side (right).
Origin & Background
This is the premier error for the 1989 series and the most frequent source of high-dollar discoveries. The 1989 dime planchet (blank coin disk) is a three-layer sandwich: two outer cupronickel layers bonded under high pressure to a pure copper core. If surface contaminants or gas pockets were present during the bonding process, the outer layer fails to adhere. When this defective planchet enters the striking chamber, one side is struck directly onto the exposed copper core — producing a coin with a silver face on one side and a copper-red face on the other.
How to Identify
- Visual: One side shows a rich coppery-red color; the other remains normal silver. The two-tone appearance is the hallmark signature.
- Luster test: The copper side must have mint luster — a reflective, struck surface proving the layer was absent before striking, not removed afterward.
- Weight test (mandatory): Use a digital scale with 0.01g precision. Standard 1989 dimes weigh 2.27 grams. A Missing Clad Layer coin weighs 1.94–2.00 grams — approximately 15% lighter due to the absent cupronickel layer.
- Obverse vs. Reverse: Either side can be missing the clad layer. Obverse (Roosevelt portrait) examples with a copper face tend to command a slight premium for visual impact.
The mandatory weight test: error coin at ~1.94g (left) vs. normal dime at 2.27g (right).
False Positives to Avoid
Environmental damage is the primary impersonator. Acids from soil, acidic beverages, or bodily fluids leach nickel from the surface, turning the coin brown or coppery. These damaged coins weigh 2.27g and have pitted, rough, matte surfaces with no luster. If it weighs 2.27g, it is damaged — full stop.
Market Values
- Circulated (brown surface): $20–$40
- Mint State MS60–63 (Red-Brown): $50–$100
- Gem MS65–66 (Full Red): $150–$250
- Certified Top Pop: $300–$500+
Auction Record
An ANACS MS63 example sold for $80.50. Current certified dealer asking prices range from $235–$500, depending on eye appeal and the preservation of Full Red (RD) color on the copper side.
1989-D Full Bands (FB) — The Ultimate Condition Rarity
Partial bands (left, most 1989-D dimes) vs. Full Bands (right) with complete separation across the torch.
Origin & Background
Full Bands (FB) is not a mint error — it is a strike quality designation for Roosevelt dimes. The horizontal bands crossing the torch on the reverse must be completely separated with no merging. Because 1989-D dies were pushed well beyond their optimal lifespan to meet the demand for 896 million coins, most 1989-D dimes show incomplete band separation. A fully sharp 1989-D strike is genuinely rare, making an MS68 FB specimen a condition rarity that eclipses most errors in dollar value.
How to Identify
- Examine the reverse torch bands under 10x magnification.
- Both sets of horizontal bands must show complete, unbroken separation across their full width — no merging at any point.
- The coin must be fully uncirculated (no wear on Roosevelt's cheekbone or hair details).
- Professional submission to PCGS or NGC is required for an official FB designation and the associated premium.
False Positives to Avoid
Partially separated bands that merge at any point do not qualify for FB. This designation cannot be self-assigned — it requires professional grading. The majority of 1989-D dimes submitted will not receive the FB designation due to overused dies.
Market Values
- MS65–66 FB: $5–$25
- MS68 FB: $600+
1989-P Doubled Die Obverse (DDO-001)
Normal LIBERTY (left) vs. DDO-001 (right) — B, E, R appear bloated and wider with reduced spacing.
Origin & Background
The 1989-P DDO-001 is cataloged in the VarietyVista database. It is a Class II (Distorted Hub) Doubled Die Obverse. To make a working die, the Mint pressed a hardened hub (master design tool) into a die blank — sometimes requiring multiple presses. If the die or hub shifted slightly between squeezes, the second impression would not perfectly align with the first. Class II doubling distorts and widens the design rather than producing a clean, separated double image. Every coin struck by this defective die shows the same characteristic thickening.
How to Identify
- Examine LIBERTY with a 10x loupe. Letters B, E, and R will appear noticeably wider or bloated compared to a normal 1989-P dime.
- The thickening is directed toward the rim — a consistent Class II characteristic.
- The negative space (gaps between letters) is visibly reduced.
- Compare directly to a reference normal 1989-P dime — Class II doubling is subtle and requires side-by-side comparison.
Machine Doubling (left, flat shelf, worthless) vs. true DDO rounded thickening (right, valuable).
False Positives to Avoid
Machine Doubling (MD) is the critical false positive. MD produces flat, shelf-like extensions beside letters that tend to disappear when you tilt the coin. Die Deterioration Doubling (DDD) — from overused dies — creates mushy, indistinct lettering. True DDO-001 shows rounded thickening with consistent directionality toward the rim. The tilt test is the fastest check: if the doubling vanishes at an angle, it is MD and worth face value. See the NGC educational guide to doubled dies vs. machine doubling.
Market Values
- Raw (unattributed): $5–$15
- MS65+ attributed: $40–$75
- MS67+ (estimated): $100+
Auction Record
No specific auction record is documented in major archives for the 1989-P DDO-001. The variety trades primarily through specialist variety dealers and attribution services.
1989 Roosevelt Dime Off-Center Strikes
Off-center 1989 dime with crescent-shaped blank area. Date visible = maximum value.
Origin & Background
An off-center strike occurs when a blank planchet is not fully seated inside the collar (the ring-shaped die that holds the coin in place) before the upper and lower dies descend. The dies strike only a portion of the planchet, leaving a crescent-shaped area of unstruck blank metal where no design was impressed. The percentage off-center determines the value tier.
How to Identify
- Design visibly bleeds off one edge with a blank crescent on the opposite side.
- The date (1989) must be visible — without it, the coin cannot be positively identified as a 1989 issue and loses most of its value.
- Estimate the percentage off-center: minor (1–10%), moderate (10–50%), major (50%+).
- The planchet shape may be slightly oblong or distorted due to unconstrained metal flow.
False Positives to Avoid
A misaligned die strike shows a slight design shift but the full design remains within the rim — this is a much more minor variety with minimal premium. Post-mint damage (bent, deformed, or gouged coins) lacks the clean crescent-shaped blank area characteristic of a genuine off-center strike.
Market Values
- 1–10% off-center: $5–$15
- 10–50% off-center: $20–$50
- 50%+ off-center with date: $100–$250
Auction Record
Heritage Auctions has sold comparable off-center Roosevelt dimes for $100–$250 depending on severity and grade. A 1989-P quarter struck 55% off-center sold at Heritage for a significant premium, illustrating the active market for major off-center strikes from this year.
1989-D Repunched Mint Mark (RPM)
Normal D mint mark (left) vs. 1989-D RPM with secondary punch visible as a notch on the serif (right).
Origin & Background
Through 1989, the mint mark was not part of the master die. Instead, a mint employee manually hammered a small steel punch into each individual working die to add the P, D, or S mark. If the first hammer blow was insufficient and the punch was struck again at a slightly different angle or position, a Repunched Mint Mark (RPM) was created — permanently on the die, and therefore on every coin that die subsequently struck. The 1990 changeover to master-die mint marks made RPMs impossible going forward, giving the 1989-D variety a historical significance as one of the last examples of this classic die variety type in U.S. coinage.
How to Identify
- Under 10x magnification, examine the D mint mark on the obverse above the date.
- A genuine RPM shows a secondary D at full relief — visible as a distinct notch or tail protruding from the main D serif, or a secondary vertical bar visible inside the curve of the D.
- Both the primary and secondary impressions must be at the same raised height — confirming this is a die feature, not surface damage.
- Varieties are cataloged by specialist services; consult Wexler's Die Varieties for known 1989-D RPM listings.
False Positives to Avoid
Machine doubling on the mint mark produces a flat, low-relief shelf beside the D — not a fully raised second impression. Machine-doubled mint marks carry no numismatic premium. An RPM shows a clearly repositioned second punch at the same relief height as the primary.
Market Values & Auction Record
The 1989-D RPM is considered a minor variety, primarily of interest to specialist variety collectors. Verified auction price data is not available from major auction houses; premium above face value varies by the prominence of the repunching and the coin's grade. Attribution by a specialist service is recommended before assigning significant value.
1989 Roosevelt Dime Broadstrike
Normal dime (left, reeded edge, 17.90mm) vs. broadstrike (right, wider diameter, smooth tapered edge).
Origin & Background
A broadstrike occurs when the collar die — the ring-shaped tool that forms the reeded edge and contains the coin during striking — fails to fully surround or deploy around the planchet. Without this restraint, metal spreads freely outward under striking pressure, producing a coin that is wider and thinner than normal with a smooth, tapered edge instead of reeding.
How to Identify
- The coin is visibly wider than the standard 17.90mm diameter.
- The edge is smooth and tapered — no reeding whatsoever.
- The full design is present on both sides — if the design is missing on part of the coin, it is an off-center strike, not a broadstrike.
- The coin appears thinner and more spread out than a normal dime.
False Positives to Avoid
Dryer coins — dimes tumbled in a household clothes dryer — are smaller in diameter with a thick, upset rim (the metal is pushed up around the edges). This is the opposite of a broadstrike. Coins with worn reeding from heavy circulation maintain their normal 17.90mm diameter. A genuine broadstrike is always wider and thinner, never smaller.
Market Values
- Circulated: $5–$10
- Uncirculated: $15–$30
- Gem MS65+: $40–$80+
1989 Roosevelt Dime: Common Traps & False Alarms
These are the three most common reasons collectors believe they have a valuable 1989 dime — and why, in nearly every case, they don't.
⚠️ Trap #1: Machine Doubling — Looks Like a DDO, Worth Nothing
Letters or numbers on the obverse appear to have a shadow or duplicate image beside them. The date or LIBERTY may seem doubled — exciting at first glance.
During striking, the die bounces or vibrates on impact, mechanically smearing the design onto the coin surface. This is a random striking artifact — not a permanent die characteristic. It is the most common misidentification for 1989 dimes by a wide margin.
- The doubled image is flat — it looks like a shelf or step beside the letter, not a rounded second image.
- Tilt the coin under a light. Machine Doubling tends to disappear or flatten at different angles.
- The letter serifs (small feet at the ends of strokes) look sheared or smeared, not split with a distinct V-notch.
- True Doubled Dies (DDO) show rounded, directional thickening. Machine Doubling looks pushed.
Value: Face value only (10¢).
⚠️ Trap #2: Environmental Damage — Looks Copper, Weighs Normal
A brown, reddish, or dark dime that looks copper-colored on one or both sides — strongly resembling a Missing Clad Layer error.
Mild acids in soil, beverages, or bodily fluids leach the nickel out of the cupronickel surface layer, leaving the underlying copper exposed and turning the coin brown or coppery over time. These are sometimes called "metal detector finds" or "cup holder coins."
- Weigh the coin on a digital scale. If it reads 2.27 grams, it is environmental damage — not a Missing Clad Layer error.
- Examine the surface. Damaged coins have pitted, rough, or matte surfaces with no mint luster.
- A genuine Missing Clad Layer coin has shiny mint luster on the copper side because the die struck the raw copper surface directly during production.
Value: Face value only (10¢).
⚠️ Trap #3: The "1989 No S" Proof Dime — A Fully Debunked Myth
The 1989-S always carries an S mint mark. No verified 1989 No S Roosevelt dime exists in any grading service population report.
A listing claiming a "1989 No S" Proof Roosevelt dime, or a 1989 dime that appears to lack the S mint mark in the mint mark area.
Real No S Roosevelt Proof dimes exist for 1968, 1970, 1975, and 1983 — genuine six-figure rarities. Collectors conflate those dates with 1989, especially since the 1989 Proof set is often stored alongside the 1990 set (which contains the verified 1990 No S Lincoln cent). Quality control at San Francisco had tightened significantly after the 1983 error, preventing recurrence in 1989.
- No verified 1989 No S Roosevelt Dime exists in PCGS or NGC population reports, or any major auction archive.
- A 1989 dime without an S mint mark is simply a 1989-P Philadelphia business strike — which never had an S to begin with.
- Coins offered as "1989 No S Proof" are either polished Philadelphia business strikes or 1989-S coins with grease filling the mint mark area.
Value: 10¢ for the P strike; $2–$5 for the actual 1989-S Proof.
1989 Roosevelt Dime Grading: How Condition Affects Value
1989 Roosevelt Dime Grading: How Condition Affects Value
U.S. coin grades run from 1 (barely identifiable) to 70 (perfect mint state). For the 1989 dime, condition matters significantly because the date is so common — only high-grade or error coins carry a meaningful premium.
- Circulated (G-4 to AU-58): Visible wear on Roosevelt's cheekbone and hair details above the ear. Worth face value without a verified error.
- Uncirculated (MS-60 to MS-63): No wear, but contact marks from bag handling are present. Small premium: $0.25–$0.50.
- Gem (MS-65 to MS-66): Near-perfect surfaces with minimal marks. $2–$5 for normal strikes.
- Superb Gem (MS-67+): Rare for 1989 given high-volume production and overused dies. Certified examples reach $25–$45+.
- Full Bands (FB): On 1989-D dimes, completely separated torch bands add a dramatic premium at MS68 — $600+.
💡 Where to Look First
The primary grading points on a Roosevelt dime are Roosevelt's cheekbone and the hair above the ear. Check these areas first under magnification. On the reverse, examine the torch bands and the word DIME along the bottom rim for wear and contact marks.
1989 Roosevelt Dime Authentication: When to Get It Certified
1989 Roosevelt Dime Authentication: When to Get It Certified
Third-party grading (TPG) by PCGS, NGC, or ANACS provides professional authentication, a numerical grade, and a tamper-evident holder — all of which substantially increase buyer confidence and resale value for genuine errors.
When certification is worth the cost:
- Missing Clad Layer: Certification is essential. The weight, luster, and surface characteristics must be professionally verified to command $235–$500. An uncertified example is very difficult to sell at full value.
- Off-Center Strikes (20%+): Certification confirms the error is genuine mint production (not post-mint damage) and assigns a grade that establishes the correct value tier.
- 1989-P DDO-001: Attribution by a TPG service or specialist reference (VarietyVista, Wexler's) is needed to obtain the attributed variety premium.
- 1989-D Full Bands: Professional grading to MS67+ FB or MS68 FB is mandatory — you cannot self-assign this designation and sell at the FB premium.
⚠️ Never Clean a Potential Error Coin
Cleaning permanently destroys mint luster and surface quality. Any TPG will assign a "details" (cleaned) grade, reducing value to near face value even on genuine errors. Handle suspected error coins by the edges only and store in a soft holder or flip.
For coin dealer referrals and show listings, consult the American Numismatic Association dealer directory at money.org.
1989 Roosevelt Dime Errors: Frequently Asked Questions
Is the 1989 Roosevelt dime worth anything?
A circulated 1989 dime with no errors is worth 10¢ — face value. Premium value exists for: verified mint errors (Missing Clad Layer up to $500+), high-grade uncirculated coins (MS67+: $25–$45), the 1989-D in Full Bands MS68 ($600+), and 1989-S Proof coins in PF70 Deep Cameo ($400+).
Does a 1989 No S Roosevelt dime exist?
No. There is no verified 1989 No S Roosevelt dime in any major grading service population report or auction archive. Real No S errors exist for 1968, 1970, 1975, and 1983 — but NOT 1989. A 1989 dime without an S mint mark is simply a Philadelphia (P-mint) business strike, which never had an S to begin with.
My 1989 dime looks doubled — is it a Doubled Die (DDO)?
Almost certainly not. In the vast majority of cases, what looks like doubling is Machine Doubling (MD) — a striking mechanical artifact with zero numismatic value. The 1989-P DDO-001 variety shows medium, rounded thickening of the LIBERTY letters (especially B, E, R) directed toward the rim. Machine Doubling is flat and shelf-like and tends to disappear when you tilt the coin. Use the tilt test before getting excited.
My 1989 dime looks copper-colored — is it a Missing Clad Layer error?
Weigh it immediately on a digital scale. A genuine Missing Clad Layer error weighs 1.94–2.00 grams (not the standard 2.27g) and has actual mint luster on the copper side. If it weighs 2.27g and the surface is rough, pitted, or matte, it is environmental damage from acid exposure — worth face value only. Weight is the final arbiter.
What year did the U.S. Mint stop hand-punching mint marks on dimes?
Starting with 1990 coinage, mint marks were incorporated directly into the master die, making Repunched Mint Marks (RPMs) impossible on subsequent dates. The 1989-D is therefore among the final Roosevelt dimes where collectors can find genuine RPM varieties — giving the series a historical distinction beyond its face value.
How many 1989 Roosevelt dimes were made?
Over 2.1 billion: 1,298,400,000 at Philadelphia, 896,535,597 at Denver, and 3,220,194 Proof coins at San Francisco. The massive circulation mintage means date rarity is not a factor. All value comes from condition or verified errors.
What tools do I need to check my 1989 dime?
Two tools cover almost every check: (1) A digital gram scale with 0.01g precision — essential for the Missing Clad Layer weight test; a coin weighing 1.94–2.00g is a strong candidate for authentication. (2) A 10x loupe (magnifying glass) — required to examine the DDO-001 thickening on LIBERTY, the RPM on the D mint mark, and the Full Bands separation on the reverse torch.
What is the most valuable 1989 dime overall?
In pure dollar terms, the 1989-D in MS68 Full Bands (FB) is the highest-value 1989 dime at $600+, making it a greater condition rarity than most errors. Among true mint errors, a certified Missing Clad Layer in top-pop condition reaches $300–$500+. The 1989-S Proof in PF70 Deep Cameo reaches $400+.

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.
