Rare 1999 Dime Errors (List & Pictures)
A wide 1999 dime may be a simple broadstrike, but a second design, a joined blank, or copper-plated zinc changes the identification. Estimated 1999 dime errors range from $15–$15,000, with a Denver cent-planchet broadstrike bringing $6,325 in April 2006.
Inspect individual coins first, then use the paired and bonded examples to understand errors that preserve several connected pieces.

1. 1999 Dime The Date or LIBERTY Has Fine Repeated Contours: Doubled Die Error
The year guide mainly discusses Philadelphia front-side doubling and also mentions Denver reports. It does not supply one exact pattern or catalog number that identifies every candidate.
A genuine doubled die has repeated detail in the striking tool. Flat ledges can instead result from movement during the strike, while reflections can make a normal edge look doubled.
How to Identify
Photograph the feature that actually looks unusual and trace the surrounding design. Rounded repeated contours matching an identified pattern carry more information than one thick letter.
A normal loose clad dime weighs about 2.268 grams and measures 17.91 mm across. Those reference measurements identify its basic type but cannot establish the cause of an extra outline.
What It’s Worth
$15–$100 is the estimate for clear, identifiable front doubling. The guide’s usual $15–$50-or-more comparison concerns subtle examples rather than a documented major variety sale.
A stronger price needs a checkable pattern and suitable preservation. A high grade cannot turn an unsupported doubled-die claim into an established variety.
2. 1999 Dime Roosevelt Appears on Copper-Colored Metal: Missing Front Clad Layer Error
A Philadelphia example graded PCGS MS62 has lost its front outer layer while retaining the ordinary reverse surface. The exposed copper core gives the portrait side its different color.
How to Identify
Compare both faces under equal lighting and inspect the edge for the absent front layer. The exposed copper should preserve original struck detail rather than grinding lines or chemical damage.
Layer loss should reduce mass, but deliberate stripping can do that too. The normal 1999-S silver Proof weighs 2.50 grams and is a separate intentional collector issue.
What It’s Worth
$100–$600 is the estimate for genuine missing-front-layer examples. The recorded Philadelphia MS62 coin brought $139 at Heritage in March 2025.
MS62 indicates an unworn coin with noticeable marks. Cleaner original copper surfaces can offer a stronger comparison than a stained or altered face.
3. 1999 Dime A Straight or Curved Gap Interrupts the Rim: Clipped Planchet Error
A clipped planchet entered the press with part of its metal already absent. The design and rim formed around that shortage.
One Philadelphia listing describes a straight-edge clip graded NGC MS65. A separate PCGS MS66 has a 20% curved clip plus a smaller rim clip.
How to Identify
Inspect the ends of each gap for original design and metal flow rather than a cut through a completed rim. A weak rim opposite the larger shortage can be helpful when present.
The second small gap belongs to the curved-clip specimen, not to every clipped dime. The straight-clip listing supplies no percentage or position to borrow from it.
What It’s Worth
$30–$250 is the estimated range for genuine clips. The 20% Philadelphia curved clip with its additional rim clip sold for $69 in March 2025.
That price covers both shortages on the same coin. Lost identifying detail or later damage can outweigh the appeal of a large clip.
4. 1999 Dime A Wide Band Surrounds a Complete Design: Broadstrike Error
The auctioned Philadelphia NGC MS66 Full Torch broadstrike has approximately a millimeter of extra border. Its metal spread without normal restraint from the collar, the ring around the blank during striking.
Full Torch describes sharply defined reverse details. It is a strike-quality designation rather than a second mint error.
How to Identify
Follow the lettering around both faces to confirm that the design remains complete inside the expanded outline. A wide photograph alone cannot establish a broadstrike.
Measure several widths and inspect the border for natural spreading. Later pressure can enlarge a finished coin while crushing letters, scraping the edge, or flattening existing relief.
What It’s Worth
$25–$200 is the estimate for ordinary genuine broadstrikes of this year. The MS66 Full Torch example sold for $49 at Heritage in April 2006.
A separate 1999-P NGC MS66 broadstrike brought $79 in March 2025. These results show that even an unworn, readily visible error need not cost hundreds of dollars.
5. 1999 Dime A Depression Interrupts the Front of a Wide Coin: Indent with Broadstrike Error
Another blank overlapping a dime can block part of the strike and leave an indent. The remaining metal may also expand when the collar does not contain it.
Heritage listed a Philadelphia NGC MS64 broadstrike with a front-side indent. The description supplies neither its percentage nor its precise position.
How to Identify
Examine the floor and boundary of the depression for a blocked strike rather than a gouge through completed detail. Then trace the expanded outline to assess the broadstrike component.
The two features should show compatible metal flow. Later squeezing can produce a depression while crushing already formed design around it.
What It’s Worth
$75–$400 is the estimate for a clear indent-and-broadstrike combination. No completed sale was supplied for the MS64 specimen.
The $49 and $79 plain-broadstrike results provide context, but the indent requires its own comparison. Price the complete coin rather than adding two full error values.
6. 1999 Dime One Strike Leaves a Blank Crescent: Off-Center Strike Error
A blank sitting partly outside the striking area receives only part of each design. The year guide reports ordinary Philadelphia and Denver examples without one shared displacement or direction.
How to Identify
Find the date and any surviving mintmark, then compare the untouched area and missing design on both faces. A missing mintmark area cannot establish Philadelphia origin.
One shifted face can indicate a misplaced die, while two distinct impressions require a multiple-strike assessment. A complete design within an uneven border can instead be an uncentered broadstrike.
What It’s Worth
$15–$75 is the estimate for a small genuine shift, rising to about $100–$600 for dramatic dated examples. No particular single off-center sale was supplied for this guide category.
Readable identity and undamaged surfaces make stronger comparisons than displacement alone. Do not add this full range again when an off-center strike is already part of a combined error.
7. 1999 Dime Several Design Impressions Survive: Multiple Strike Error
A retained or returning coin can be struck again after moving, leaving related groups of displaced detail. A 1999-D NGC MS66 is described as struck four times.
A separate Philadelphia PCGS MS66 has impressions 20% and 75% off center. Another Denver double-strike report places its second impression 95% off center.
How to Identify
Trace each repeated portrait, date, or rim into a coherent design position. Count only impressions supported by several related features, not isolated shelves beside letters.
Check how later impressions cross or erase earlier detail on both faces. The three reported coins must retain their own percentages and strike counts.
What It’s Worth
$250–$3,000 is the estimate for clearly identified multiple strikes. NGC reports a $2,040 March 2023 result for the Denver four-strike MS66.
The Philadelphia 20%-and-75% double strike sold for $493.50 in January 2016. Recognizable surviving impressions matter alongside the number of blows.
8. 1999 Dime A Cup Wall or Obstructed Face Records a Stuck Coin: Die Caps and Cap Strikes Error
A coin adhering to a die can expand upward around it as more blanks are struck, forming a die cap. A later coin struck beneath that cap receives an obstructed impression instead of becoming the same object.
Known examples include a deep Philadelphia cap and a Denver front-side cap. A separate Philadelphia title reading Deep Capped Die Strike lacks enough description to settle its exact form.
How to Identify
Use a side view to determine whether the coin has an original rising wall or merely an affected face. Later bending can leave sharp folds, tool marks, and crushed detail.
A receiving coin needs evidence of an original cap-obstructed strike; clear mirror detail may not survive on every late-stage example. Do not resolve an ambiguous auction title by assuming a cap’s side or shape.
What It’s Worth
$300–$1,500 is the estimate for clearly identified cap-related pieces. The Philadelphia MS64 deep cap sold for $546.25 in February 2010.
PCGS records $1,150 for the Denver MS64 front cap in April 2006. The separately titled MS67 capped-die strike brought $493.50 in January 2016.
These descriptions and prices belong to different objects. An unfamiliar coin’s mechanism must be established before choosing the closest comparison.
9. 1999 Dime Several Impressions Cover an Irregular Fragment: Multiple-Struck Scrap Error
A Philadelphia PCGS MS65 example carries multiple dime impressions on an irregular scrap blank weighing 1.46 grams. Its light mass and unusual outline are part of the attribution.
The supplied listing does not specify the exact number or direction of all strikes. Extra fragments of design should not be converted into an invented sequence.
How to Identify
Follow the original struck detail to the irregular boundaries and inspect for later cuts through finished design. A normal dime trimmed afterward can also be lightweight.
Record the fragment’s actual mass and dimensions without expecting a round dime shape. The evidence should show that the fragment was already irregular when it received its impressions.
What It’s Worth
$300–$2,500 is the estimate for an identified multiple-struck scrap piece. No completed sale was supplied for the 1.46-gram MS65 specimen.
The conventional Denver four-strike dime’s $2,040 result provides broad context only. Its original blank and outline differ from this scrap-struck object.
10. 1999 Dime A Wide Brown Dime Has a Zinc Core: Broadstrike on a Cent Planchet Error
The Denver PCGS MS64 Brown example combines a dime design with a copper-plated zinc cent blank and broadstriking. Heritage describes exposed zinc in small areas on both faces and stretched outer lettering.
The metal is copper plating over zinc, not zinc over copper. This blank had not already received a Lincoln design.
How to Identify
A normal modern cent blank starts near 2.50 grams and 19.05 mm, before any expansion in the dime press. These standards are reference figures, not the recorded measurements of the auction specimen.
Inspect plating, zinc exposures, and original struck detail without scraping the metal. Added color on an ordinary dime or a surviving earlier Lincoln design would require a different explanation.
What It’s Worth
$3,000–$15,000 is the estimated range for comparable authenticated cent-planchet broadstrikes. The PCGS MS64 Brown specimen brought $6,325 in April 2006.
The wrong blank and broadstrike contribute to one whole-coin value. Original metal and professional attribution matter more than a brown color or a wide outline alone.
11. 1999 Dime Two Matching Coins Include a Backward Impression: Double-Struck Brockage Pair Error
This Philadelphia pair contains a double-struck ANACS MS62 and a second coin graded MS63 that is both double struck and brockaged. Brockage is a sunken mirror image impressed by another struck coin.
How to Identify
Compare photographs of the contact areas and trace how raised detail on one coin could produce reversed detail on the other. Both pieces must also retain evidence of their additional strikes.
Keep certified pieces sealed rather than pressing them together. Matching contact shape and design connect a pair more convincingly than a shared date.
What It’s Worth
$350–$1,000 is the estimate for a complete, clearly matched pair. The two ANACS coins sold together for $552 at Heritage in July 2021.
The amount covers both partners and their connected evidence. It is neither a per-coin price nor a separate full premium for each named feature.
12. 1999 Dime Two Cups Have Compatible Plain Contact Faces: Mated One-Sided Caps Error
Two blanks entering together can shield their touching faces while their outer faces receive the dies’ designs. A Philadelphia pair graded PCGS MS66 on both pieces formed one-sided caps with rising walls.
Heritage explained that the blanks apparently remained through several strikes before separating. Their plain contact faces differ from the mirror-design contact in the brockage pair.
How to Identify
Compare the facing surfaces and meeting outlines before focusing on the cups’ height. The shapes should explain how the blanks blocked each other during striking.
Look for original wall formation rather than later folds or tool marks. Do not force the pieces together or remove them from their certified holders.
What It’s Worth
$1,000–$3,500 is the estimated range for a complete compatible pair. The two PCGS MS66 caps sold for $2,185 at Heritage in May 2008.
One separated partner no longer presents the same complete evidence. Two unrelated cupped dimes with matching dates do not provide an equivalent comparison.
13. 1999 Dime A Stretched Coin Matches a Folded Clipped Partner: Complex Overlapping Pair Error
Heritage described two Philadelphia pieces in which an incomplete blank folded beneath a stretched coin and left a contact impression. The explanation also involves a third blank, with remnants left on a reverse.
Only two main pieces were sold, and neither was certified. The clipped piece’s tail later received a flipped-over strike approximately 95% off center.
How to Identify
Locate the folded portion, its matching contact hollow, and the tail’s separate impression in photographs of both pieces. The 95% description applies to that last tail strike, not to the whole pair.
Leave attached remnants undisturbed. Clipping, stretching, and retained fragments mean the objects should be documented individually rather than assumed to have two ordinary dime weights.
What It’s Worth
$400–$2,000 is the working estimate for a convincingly matched complex pair. The two-piece combination sold for $603.75 at Heritage in August 2001.
The sale does not include a third intact dime. Lost fragments or later damage can make the linked striking sequence harder to demonstrate.
14. 1999 Dime Several Blanks Remain Joined: Bonded Coins Error
Overlapping blanks can become bonded under striking pressure. A three-piece Philadelphia NGC MS64 combination carries dime detail across joined metal and an additional impression on its lowest blank.
That lower impression is described as about 80% off center. A separate Philadelphia PCGS MS64 object contains two bonded pieces, and a small cheek cut on the three-piece example is later damage.
How to Identify
Count the visible blank outlines and follow struck design through the overlaps without trying to separate anything. Glue, solder, or joins interrupting finished detail can indicate later assembly.
The extra 80% impression belongs only to the lowest blank of the three-piece object. No measured total weights are supplied for either combination.
What It’s Worth
$1,500–$5,000 is the estimate for a genuine intact bonded combination of this kind. The three-piece NGC MS64 object sold for $3,055 in January 2014.
The separate two-piece PCGS MS64 combination brought $3,360 in July 2021. Their results demonstrate that blank count alone does not determine value.
Conclusion
A useful 1999 dime identification accounts for the complete object: its metal, outline, impressions, and any connected partners. A wide border alone says less than the relationship between the design and the way the metal moved.
Preserve pairs, attached fragments, and original joins while documenting them. Compare whole-coin or whole-pair results with the same mechanism, keeping each specimen’s grades and measurements separate from similar-looking examples.
