2022 Roosevelt Dime Errors: Value Guide & Rare Varieties
2022 Roosevelt Dime error value guide (updated Jan 2026). Die chips $2–$10, missing clad layer $50–$250+, off-center strikes $5–$100+. Learn to avoid machine doubling—the #1 worthless trap.
Most 2022 Roosevelt Dimes are worth face value ($0.10), but three real manufacturing errors can push value to $2–$250+.
- 💰 Missing Clad Layer — copper-colored face + weight below 2.10 g: $50–$250+
- 💰 Off-Center Strike — blank crescent of unstruck metal, date visible: $5–$100+
- 💰 "Drooling George" Die Chip — raised metal blob on Roosevelt's jawline: $2–$10
- 💎 2022-S Silver Proof — solid silver edge, weighs ~2.50 g: $15–$25
⚠️ The #1 trap is Machine Doubling — flat, shelf-like doubling on "2022" or "LIBERTY" that looks like an error but is worth face value only. No major Doubled Die varieties (DDO/DDR) have been verified for the 2022 Roosevelt Dime by CONECA or VarietyVista as of January 2026.

No major Doubled Die varieties (DDO/DDR) have been verified by CONECA or VarietyVista for the 2022 Roosevelt Dime as of this report.
Die chips ("Drooling George") are common die deterioration defects, not design varieties. Premiums are modest ($2–$10).
Machine Doubling (flat, shelf-like doubling) is NOT a valuable error — it is the #1 false alarm for 2022 dimes.
Professional authentication (PCGS/NGC) is only cost-effective for errors expected to be worth over $100. Grading fees typically run $40–$60+.
eBay listings claiming "WDDO-001" for 2022 dimes are often unverified seller attributions or misattributed from other denominations such as the 2022 Jefferson Nickel.
Over 3.1 billion 2022 Roosevelt Dimes rolled off Philadelphia and Denver presses — yet a small fraction carry real manufacturing flaws worth real money. Missing clad layers, off-center strikes, and die chips are out there in circulation right now. See our full 2022 Roosevelt Dime value guide for standard prices by grade. This guide focuses on errors: which ones pay, which ones are traps, and exactly how to tell the difference.
2022 Roosevelt Dime: Specifications & Mintage
Every error hunt begins with knowing what "normal" looks like. A coin matching all specs below needs a genuine manufacturing flaw — not just discoloration or wear — to be worth more than face value.
| Mint | Type | Mintage | Composition | Weight | Diameter | Typical Value |
|---|---|---|---|---|---|---|
| Philadelphia (P) | Business Strike | 1,551,000,000 | Cu-Ni Clad | 2.27 g | 17.91 mm | $0.10–$0.50 |
| Denver (D) | Business Strike | 1,583,000,000 | Cu-Ni Clad | 2.27 g | 17.91 mm | $0.10–$0.50 |
| San Francisco (S) | Clad Proof | ~397,000 sets | Cu-Ni Clad | 2.27 g | 17.91 mm | $2–$5 |
| San Francisco (S) | Silver Proof | ~296,000 sets | 99.9% Silver | ~2.50 g | 17.91 mm | $15–$25 |
ℹ️ Weight Tolerance Explained
A genuine 2022 dime legally weighs 2.178 g–2.358 g (±0.09 g statutory tolerance). A coin reading 2.20 g on your scale is not a thin planchet error — it is within spec. Only weights clearly outside this range (below ~2.10 g or above ~2.40 g) warrant further investigation.
2022-S Silver Proof vs. Clad Proof: How to Tell
Left: Clad Proof with visible copper stripe on edge. Right: Silver Proof with solid silver-colored edge.
Clad Proof (~397,000 sets) — $2–$5
- Visible copper stripe on the edge (three-layer sandwich)
- Weighs 2.27 g
- Mirror-like fields with frosted devices; "S" mintmark
Silver Proof (~296,000 sets) — $15–$25
- Solid, uniformly silver-colored edge — no copper stripe
- Weighs ~2.50 g (silver is denser than clad)
- Has intrinsic precious metal value; not meant for circulation

2022 Roosevelt Dime Quick Checks: Do You Have an Error?
Run these three checks before going further. Two identify real, potentially valuable errors. The third identifies the most common worthless lookalike. You need a 10x loupe and a digital gram scale accurate to 0.01 g.
Left: Normal 2022 dime at 2.27 g. Right: Suspect coin at 1.88 g—possible missing clad layer.
Check 1: The "Drooling George" Die Chip
The obverse (front) profile of President Roosevelt — specifically the corner of the mouth, the chin, and the jawline.
A distinct, raised irregular blob or accumulation of metal resembling a wart, a drop of liquid, or a second chin. It is physical metal rising above the surrounding coin surface — not a pit, scratch, or discoloration.
Scratches, gouges, or indentations (damage going into the coin) are Post-Mint Damage worth nothing. Staining and dark discoloration are also not die chips. The feature must physically rise above the field — if it doesn't catch light from below when you tilt the coin, it is likely damage.
Check 2: Missing Clad Layer (Weight & Edge)
The edge (the "third side") for color, and your digital scale for weight. Then examine whether one entire face of the coin is copper-red with no silver-colored nickel layer.
Visual: One side solid copper-red with no nickel layer, sometimes with weak strike detail. Weight: 1.80 g–2.00 g suggests one layer missing; ~2.50 g suggests a possible silver planchet error.
A dark-red, brown, or black coin that weighs ~2.27 g is Environmental Damage — corrosion from soil, cup holders, or a washing machine. A plated coin also weighs normal. Weight is the non-negotiable test: without a low reading, there is no error.
Check 3: Machine Doubling — The #1 Worthless Trap
The date "2022", "LIBERTY", and "IN GOD WE TRUST" — anywhere letters or numbers appear doubled.
Machine Doubling shows flat, shelf-like secondary images — as if the letter was smeared or sheared sideways. The secondary image lacks volume, often reducing the letter's width. Caused by the die bouncing after striking; extremely common on 2022 dimes.
True Hub Doubling (DDO/DDR) shows rounded, bulbous secondary images with split serifs — like a second full letter, not a smear. No major DDO or DDR has been verified for the 2022 Roosevelt Dime by CONECA or VarietyVista as of January 2026.
💡 When to keep digging
Continue investigating only if your coin weighs outside 2.10 g–2.40 g, shows a distinct raised blob of metal, has a blank crescent of unstruck area, or measures wider than 17.91 mm in diameter. Otherwise, you almost certainly have a normal coin or Post-Mint Damage.

2022 Roosevelt Dime Valuable Errors: Detailed Guides
No confirmed doubled-die varieties exist for 2022. The real value lies in planchet and strike errors. Here are the four that matter — with full diagnostics and current market values.
2022 "Drooling George" & Torch Die Chips
Normal Roosevelt jawline (left) vs. "Drooling George" die chip with raised blob at the mouth corner (right).
Origin & Background
With 3.1 billion coins struck across two mints, the Roosevelt portrait dies undergo extreme repeated stress. The sharp corner of the die where the jaw meets the flat field is a high-stress transition zone. After thousands of strike cycles, micro-fractures develop in the tool steel and a small flake of steel detaches — creating a void. On subsequent strikes, coin metal flows into that void just as it fills the design, producing a raised blob on the coin. The reverse torch face has similar vulnerability at the flame tips and vertical band edges. Because breakage is irregular, no two die chips are identical, though they cluster in predictable zones.
How to Identify
- Under a 10x loupe, the blob is raised above the coin surface — it catches light from below when you tilt the coin
- Shape is irregular and lumpy, not uniform — resembles a broken chip of steel filled with metal
- "Drooling George" clusters at the mouth, chin, and jawline on the obverse
- Torch chips appear as extra metal fusing flame tips or filling spaces between the torch bands on the reverse
- Roosevelt's hair is another common zone — chips may create "horns" above the portrait
Normal torch flame tip (left) vs. torch die chip with extra raised metal at the flame edge (right).
False Positives to Avoid
A scratch or gouge going into the coin is Post-Mint Damage — worth nothing. Staining or dark discoloration is not a die chip. The feature must physically rise above the surrounding surface. If it does not catch light from below when you tilt the coin under a single light source, it is damage, not a die chip.
Market Values & Auction Record
- • "Drooling George" (obverse jaw/mouth): $2–$10 raw
- • Torch / Flame chip (reverse): $1–$5 raw
~$6.00 for a 2022-P "Drooling George" die chip (eBay sold listing). ~$4.20 for a 2022-P reverse torch chip (eBay sold listing). These represent retail convenience premiums; a dealer would likely pay face value for either. Not worth certifying — grading fees exceed the coin's value.
2022 Missing Clad Layer
Standard clad dime (left) vs. full missing clad layer with bright copper-red obverse (right).
Origin & Background
The standard 2022 dime is a layered "sandwich": copper-nickel outer layers bonded under extreme pressure to a pure copper core. If the bonding process is imperfect — due to gas bubbles or surface contaminants during manufacture — the nickel layer may fail to adhere and peel away before or after the strike, leaving the copper core exposed on one side. This is a genuine manufacturing defect, not a chemical reaction that happened after the coin left the Mint.
How to Identify
- Weigh the coin first — this is non-negotiable. Partial missing (10–40%) weighs ~2.20–2.25 g; majority missing (40–90%) weighs ~2.00–2.15 g; full one-side missing weighs ~1.80–1.95 g
- The copper face is bright red-orange, without any silver nickel surface
- Strike detail may appear weak or shallow on the affected side — a thinner planchet doesn't fill the die cavity as well
- A full two-sided missing clad (solid copper core) is extremely rare and requires certification before value can be established
Severity & Values
| Severity | Weight Est. | Circulated Value | Mint State Value |
|---|---|---|---|
| Partial (10–40% missing) | ~2.20–2.25 g | $5–$15 | $20–$40 |
| Partial (40–90% missing) | ~2.00–2.15 g | $15–$30 | $40–$80 |
| Full Missing (1 side) | ~1.80–1.95 g | $50–$100 | $150–$250 |
| Full Missing (2 sides) | ~1.50–1.70 g | Certification required | High premium |
False Positives to Avoid
Environmental Damage from corrosion (soil, cup holders, washing machines) produces dark red or brown coins that still weigh ~2.27 g — it is chemical alteration, not a manufacturing defect. Plated coins also weigh normal. An improperly annealed planchet may cause pink or reddish toning at full weight — a different, lesser error worth $5–$20. Weight is the definitive test every time.
Auction Record
No verified 2022-specific missing clad layer record from Heritage or Stacks Bowers as of January 2026, reflecting the recency of the issue. Values are based on general mint error class pricing.
2022 Off-Center Strike
~35% off-center 2022 dime with blank crescent of unstruck metal and visible "2022" date.
Origin & Background
Modern Schuler presses at the US Mint use laser sensors and load monitors to detect misaligned or misfed planchets. If the sensor detects an anomaly, the press typically stops or mechanically ejects the coin for destruction. A genuine 2022 off-center dime must defeat this detection system and escape in a sealed bag — making it a legitimate rarity. No verified auction records from major houses have surfaced for this issue yet, simply because so few have entered the market.
How to Identify
- Part of the design is missing and a blank, unstruck crescent of metal is visible on the opposite side — where the die never contacted the planchet
- Estimate the percentage: how much design is missing relative to what is present
- Date visibility is the critical value factor — a coin missing the date "2022" is far less valuable than one showing it
- Greater than 50% off-center with a visible date commands the highest premiums
Severity & Values
| Off-Center % | Notes | Value |
|---|---|---|
| < 10% | Design cut at rim only; full date visible | Face–$2 |
| 10–20% | Missing letters; date visible | $5–$15 |
| 20–50% | Dramatic crescent; date visible | $20–$50 |
| > 50% | Majority blank; date MUST be visible for top value | $50+ |
| Unstruck Planchet | Blank disk with upset rim (Type II) | $2–$5 |
False Positives to Avoid
A Misaligned Die (MAD) strike shows the full design but shifted slightly within the rim — these are common and worth face value to $5. True off-center strikes show a blank unstruck planchet area where the die never contacted the metal. A coin missing the date has dramatically lower value regardless of how dramatic the shift looks.
Auction Record
No verified 2022 Roosevelt Dime off-center record from major auction houses as of January 2026.
2022 Broadstrike (Missing Collar Error)
Broadstrike with spread design, larger diameter, smooth edge (left) vs. dryer coin with smooth edge but normal/smaller diameter (right).
Origin & Background
During a normal strike, a collar die — a retaining ring surrounding the planchet — prevents the metal from spreading outward and simultaneously forms the reeded edge. If the collar is absent or misfires, the coin metal spreads freely under striking pressure. The result is a coin with a full design, no reeding, and a diameter that exceeds the standard 17.91 mm.
How to Identify
- Coin is wider than 17.91 mm — measure with calipers. This is the single most reliable test.
- The edge is completely smooth — no reeding at all
- Full design is present but the devices spread toward the rim area
- The rim itself is lower or flatter than on a normal dime
False Positives to Avoid
A "Dryer Coin" — trapped in a commercial dryer drum and tumbled — develops a smooth edge from mechanical abrasion, but its diameter is the same or smaller than 17.91 mm. The rolling action compresses the rim inward. A true broadstrike is always larger in diameter. Always measure before claiming a broadstrike.
Market Values & Auction Record
Estimated value: $10–$25. No verified 2022 broadstrike auction record exists as of January 2026.
2022 Roosevelt Dime: Common Traps & What Looks Valuable But Isn't
The vast majority of "errors" found in 2022 dime rolls fall into these four categories. Recognizing them quickly saves time and prevents costly grading submissions.
Machine doubling (flat staircase shelves, left) vs. true hub doubling (rounded secondary image, right). Only hub doubling is valuable.
⚠️ Machine Doubling (Mechanical Doubling)
Flat, shelf-like steps alongside the date "2022," "LIBERTY," or the letters in the motto. Appears as if the letters were smeared or sheared sideways. Extremely common on 2022 dimes due to high-speed production.
If the die bounces or drags slightly across the coin immediately after the strike — before fully retracting — it shears metal from the newly formed letters. This creates flat secondary impressions. It is a mechanical flaw of the press, not a design error — and has no numismatic value.
- The secondary image is flat like a staircase step, not rounded like the original letter
- It reduces letter width (eats into the primary letter) rather than adding width
- Rotate the coin under a single light source: Machine Doubling lies flat in shadow, while true doubled die elements catch the light just like the primary design
- No major DDO or DDR is verified for the 2022 Roosevelt Dime — any doubling found is almost certainly Machine Doubling
Value: Face value only.
⚠️ Environmental Damage ("Red," Brown, or Black Dimes)
A 2022 dime that is copper-red, dark brown, or black. The copper core in clad coins is chemically reactive and discolors from prolonged exposure to moisture, soil, cup holders, or swimming pool chemicals.
Chemical reactions after the coin left the Mint strip, stain, or alter the surface. This is Post-Mint Damage (PMD) — a manufacturing defect does not cause this. It happened in a pocket, parking lot, or junk drawer, not at the US Mint.
- Weigh it: if the scale reads ~2.27 g, both clad layers are intact — it is chemical damage, not a Missing Clad Layer
- A genuine Missing Clad Layer is a manufacturing defect where the layer never bonded; Environmental Damage is a chemical alteration after striking
- Environmental damage often shows patchy, uneven, or gradient discoloration — not a clean, uniform copper face
Value: Face value only.
⚠️ Dryer Coin (Smooth-Edge Broadstrike Imposter)
A dime with a smooth or partially smooth edge — no reeding — and possibly a raised, thick rim.
The coin gets trapped between the drum of a commercial dryer and tumbles repeatedly. Mechanical abrasion gradually beats the reeded edge flat over many cycles. Post-Mint Damage — not a Mint error.
- Measure diameter with calipers: a Dryer Coin is 17.91 mm or smaller — tumbling compresses the rim inward
- A genuine Broadstrike (missing collar) is larger than 17.91 mm — the metal spread outward freely during striking
- Dryer Coins show mechanical abrasion and surface wear inconsistent with a Mint-fresh coin
Value: Face value only.
⚠️ eBay "WDDO-001" Listings
A 2022 dime listed as "Rare WDDO-001" or "DDR" on eBay or similar platforms, often priced $20–$100+.
Search algorithms conflate "2022 WDDR-001" — a verified Jefferson Nickel variety — with the Roosevelt Dime. Sellers apply variety codes from other denominations to inflate perceived value. Social media "treasure hunting" content amplifies the confusion.
- Cross-reference against authoritative databases: Wexler's Roosevelt Dime DDO listings and VarietyVista Roosevelt DDO Listings
- No major DDO or DDR appears for the 2022 Roosevelt Dime in either database as of January 2026
- "WDDR-001" for 2022 most commonly refers to the Jefferson Nickel — a completely different coin
Value: Face value only (unless verified by CONECA or VarietyVista).
2022 Roosevelt Dime Grading: How Condition Affects Error Value
For 2022 dimes, grade is most important for error coins. A full Missing Clad Layer in Mint State (no wear, original luster intact) commands significantly more than the same error in circulated condition — see the severity table in the Missing Clad Layer section.
For standard non-error 2022 dimes, the value picture is simple:
- Circulated (any grade with visible wear): Face value ($0.10) — over 3 billion were struck, so these are extremely common
- Uncirculated (MS-60 to MS-65): $0.20–$0.50 typical retail
- Gem Uncirculated (MS-67+): Premium grades command more; the record is approximately $700 for a perfect MS-69 2022-P Dime, per PCGS CoinFacts
⚠️ Error Value vs. Grade: Which Matters More?
For 2022 dimes, a genuine planchet or strike error in circulated condition is almost always worth more than a perfect MS-69 non-error coin. Prioritize identifying errors. Grade is a secondary value multiplier, not the primary driver.
2022 Roosevelt Dime Authentication: Tools, Thresholds & When to Certify
Essential Tool Kit
- Digital Gram Scale (0.01 g accuracy): Non-negotiable for detecting clad layer errors. A scale rounding to 0.1 g is useless — the tolerance is smaller than its rounding error.
- 10x–16x Triplet Loupe: A "Triplet" lens corrects for color fringing and image distortion. Essential for distinguishing Machine Doubling (flat shelves) from Hub Doubling (rounded secondary images).
- Calipers: Required to measure diameter and confirm Broadstrike versus Dryer Coin.
Stop / Go Decision Guide
🛑 STOP — Spend It
- Flat, shelf-like doubling that disappears when you change the light angle
- Dark or discolored coin weighing 2.17–2.36 g
- Anomaly goes into the coin (scratch, gouge, pit)
- Smooth edge with diameter 17.91 mm or smaller (Dryer Coin)
- Ring indentation inside the rim (damage from a coin sorting machine)
✅ GO — Keep & Investigate
- Weight below 2.10 g or above 2.40 g
- One face is solid copper-red with no nickel layer
- Blank crescent of unstruck metal visible, date still present
- Diameter measurably larger than 17.91 mm with smooth edge
- Large raised mass of metal on the rim extending into the field (Retained Cud)
When to Submit to PCGS or NGC
Professional certification by PCGS or NGC is only financially justified when the error is expected to be worth over $100. Economy-tier grading fees typically run $40–$60 plus shipping and handling.
- ✅ Certify: Full Missing Clad Layer, significant Off-Center Strike (>25% with date), confirmed Broadstrike, large Retained Cud
- ❌ Do not certify: Die chips ("Drooling George") — a $5 eBay find does not justify a $50+ grading fee. That is a guaranteed financial loss.
For coin dealer referrals and guidance on selling error coins, consult the American Numismatic Association (ANA) dealer directory or your nearest local coin club.
2022 Roosevelt Dime Errors: Frequently Asked Questions
My 2022 dime has doubled letters. Is it a valuable DDO?
Almost certainly not. The most common lookalike for 2022 dimes is Machine Doubling — flat, shelf-like secondary images caused by a loose die dragging across the coin after striking. It is worth face value only. No major Doubled Die Obverse (DDO) or Doubled Die Reverse (DDR) has been verified for the 2022 Roosevelt Dime by CONECA or VarietyVista as of January 2026.
My 2022 dime is copper-colored. Is it worth money?
Weigh it first. If it reads ~2.27 g, the copper color is Environmental Damage — corrosion from a cup holder, soil, or washing machine — worth face value. If it weighs below 2.10 g and one entire side is bright copper-red with no nickel layer, you likely have a Missing Clad Layer error worth $50–$250 depending on severity and grade. Weight is the definitive test.
What is a "Drooling George" and is it rare?
A "Drooling George" is a raised blob of metal at Roosevelt's jawline or mouth, formed when a piece of the die breaks away during striking and the void fills with coin metal on subsequent strikes. It is common — not rare — on 2022 dimes because the massive 3.1 billion coin production run wears dies down quickly. Retail value is $2–$10 raw. Grading fees ($40–$60+) far exceed its worth, so do not certify these.
How do I tell a 2022-S Silver Proof from a Clad Proof?
Check the edge and weigh it. Clad Proof: visible copper stripe on the edge, weighs 2.27 g, worth $2–$5. Silver Proof: solid, uniformly silver-colored edge (no copper stripe), weighs ~2.50 g, worth $15–$25. Both have an "S" mintmark. The Silver Proof also carries intrinsic precious metal value beyond its numismatic premium.
I found a smooth-edged 2022 dime. Is it a Broadstrike?
Measure the diameter with calipers. A genuine Broadstrike (struck without the collar retaining ring) will be larger than 17.91 mm because the metal spread freely during striking. A Dryer Coin — the most common smooth-edge imposter — is the same size or smaller due to mechanical tumbling in a commercial dryer. If diameter is 17.91 mm or less, it is a Dryer Coin worth face value.
Should I clean my 2022 error dime before sending it to PCGS or NGC?
Never clean an error coin. Cleaning destroys original luster and surface integrity. Both PCGS and NGC can detect cleaning and will assign a "details" grade, which dramatically reduces value and resale appeal. If you believe you have a genuine error worth certifying, submit it exactly as found.
Why are 2022 off-center dimes so rare compared to older decades?
Modern Schuler presses at the US Mint are equipped with laser sensors and load monitors that detect misaligned or misfed planchets. A misfed planchet typically triggers an automatic stop or mechanical rejection into a destruction bin. A genuine 2022 off-center dime must defeat this detection system to escape in a sealed bag — which explains why virtually none have surfaced at major auction houses yet.
What is the highest price ever paid for a 2022 Roosevelt Dime?
The highest recorded price for a standard (non-error) 2022-P dime is approximately $700 for a perfect MS-69 specimen, per PCGS CoinFacts. That reflects extreme grade rarity for a modern coin, not an error premium. The vast majority of 2022 dimes — including many Uncirculated examples — are worth $0.10–$0.50.
