1999 Dime Value By Variety
The 1999 Roosevelt dime was produced across three U.S. Mint facilities in four distinct varieties. Philadelphia (P) and Denver (D) struck circulation coins by the billions. San Francisco (S) made two special collector-only proof versions: one in standard copper-nickel clad and one in 90% silver.

Most Valuable 1999 Dime Chart
2000 - Present
The auction data above reveals a jaw-dropping spread in value. The most expensive 1999 dime sold — a 1999-D struck on a cent planchet graded MS65 — fetched $14,375. The least expensive item on the list, a 1999-S Silver PR69, sold for just $92. That’s a 156-times difference between the rarest error coin and the most common proof.
Those top-priced 1999-D coins are not regular dimes. They are wrong-planchet error coins struck on copper cent blanks, producing unusual blue-green, violet, and gold-orange surface colors. Only two confirmed examples exist worldwide.
Grade condition has an enormous effect on value even within the same error. A 1999-D wrong-planchet error in MS65 brought $14,375, while an MS64 example of the same error sold for $6,325 — one grade point lower and the value dropped 56%.
A regular 1999-D in MS65 is worth roughly $5–$7 in today’s market. That’s the everyday reality for the vast majority of coins from this year.
History Of The 1999 Dime
The Roosevelt dime was introduced on January 30, 1946 — Franklin D. Roosevelt’s birthday — less than a year after his death on April 12, 1945. The Coinage Act that authorized the new design didn’t even require a congressional vote; the ten-cent denomination could be redesigned at the Treasury’s discretion, which let officials move quickly.
Chief Engraver John R. Sinnock — who had been in his position since 1925 and had already designed FDR’s 1941 inaugural medal — was chosen to create the new coin. His first submission in October 1945 was rejected by the Commission of Fine Arts as lacking dignity. After multiple rounds of revisions and meetings with commission sculptor Lee Lawrie, Treasury Secretary Fred Vinson finally approved the third draft on January 8, 1946. The Philadelphia Mint struck the first examples just 11 days later on January 19.
The coin’s design carries symbolism rooted in both wartime and FDR’s personal legacy. The reverse features a flaming torch (liberty) flanked by an olive branch (peace) and an oak branch (strength) — a trio of values that resonated deeply after World War II. Numismatic historian David Lange described Sinnock’s original intent as creating the “highest relief possible for a circulation-strike dime,” giving it what Lange called “a true sculptural quality” in a November 1999 article in The Numismatist.
Two controversies followed the dime’s release. Some people falsely claimed the “JS” initials on the obverse stood for Joseph Stalin — Cold War paranoia at work. A separate controversy alleged that Sinnock copied his Roosevelt portrait from sculptor Selma Burke’s 1944 bronze bas-relief of FDR. The Mint denied the allegations, and the debate has never been fully resolved.
By 1999, the Roosevelt dime had been in continuous production for 53 years without a major design change. The 1999 issue became a small artifact of America’s late-1990s economic golden age — over 3.5 billion coins minted in a single year to serve a booming economy.

Key Features Of The 1999 Dime
Understanding the physical design and specifications of the 1999 dime helps collectors and beginners alike identify and evaluate these coins. This section covers the design details on both sides plus the coin’s technical specifications.
The Obverse Of The 1999 Dime
The obverse shows a left-facing portrait of President Franklin D. Roosevelt — the same design Sinnock created in 1946 and essentially unchanged since. The word “LIBERTY” curves along the left rim, and “IN GOD WE TRUST” sits horizontally at the seven o’clock position near his neck.
The date “1999” appears to the right of Roosevelt’s bust, and Sinnock’s initials “JS” are engraved just below the neck cutoff. Since 1968, the mint mark — P, D, or S — has been positioned on the obverse just above the date, moved from its original reverse location.
One piece of Roosevelt dime history worth knowing: when the coin first appeared in 1946, some people wrongly claimed the “JS” initials stood for Joseph Stalin, a product of early Cold War tension in the United States. The initials are, of course, those of designer John R. Sinnock.
The Reverse Of The 1999 Dime
The reverse centers on a flaming torch representing liberty, flanked by an olive branch on the left (peace) and an oak branch on the right (strength). This symbolic trio was designed to reflect American values emerging from World War II.
“E PLURIBUS UNUM” (Latin for “out of many, one”) runs horizontally across the base of the torch, while “UNITED STATES OF AMERICA” arcs around the top and “ONE DIME” sits along the bottom rim.
The torch bands — the two horizontal lines crossing the lower section of the torch — are critical for collectors. When these bands show complete, unbroken separation, the coin earns a “Full Bands” (FB) designation, which significantly increases its value.
Other Features Of The 1999 Dime
The 1999 dime measures 17.90 mm in diameter and weighs exactly 2.27 grams. Its edge features 118 individual reeds, which serve both as an anti-counterfeiting measure and the coin’s signature textured feel.
The composition is copper-nickel clad: an outer layer of 75% copper and 25% nickel over a pure copper core. This composition replaced 90% silver with passage of the Coinage Act of 1965, which changed U.S. coinage in response to rising silver prices and hoarding. The clad structure means the coin has no precious metal content — its value is purely numismatic.
Worth noting: the 1999-S Silver proof version breaks from this pattern, as it is struck in 90% silver. Starting in 1992, the U.S. Mint resumed producing silver proof dimes for annual Silver Proof Sets — and the 1999-S silver proof is part of that series.

1999 Dime Mintage & Survival Data
1999 Dime Mintage & Survival Chart
Survival Distribution
| Type | Mintage | Survival | Survival Rate |
|---|---|---|---|
| P | 2,164,000,000 | unknown | unknown |
| D | 1,397,750,000 | unknown | unknown |
| S DCAM | 2,543,401 | 2,416,230 | 95% |
| S Silver DCAM | 800,000 | 760,000 | 95% |
The chart above reveals a massive production gap between circulation strikes and collector issues. Philadelphia and Denver together produced over 3.5 billion dimes for commerce, while San Francisco’s combined proof output barely topped 3.3 million.
Survival rates for P and D circulation coins are essentially unknown — these dimes entered active commercial use and experienced wear, loss, and destruction over 25+ years. By contrast, both San Francisco proof varieties show roughly 95% survival rates, because collectors stored them in protective packaging and never spent them.
The proof coin survival rate also reflects a key market dynamic: high supply of preserved examples at the top grades continues to push PR70 values downward over time, as newly submitted coins constantly increase the population at premium grades.

Within seconds, you’ll see its current market value based on real-time data from thousands of actual sales. No more guessing whether those torch bands are “full” enough or wondering if that tiny mark is a valuable error.
The app does the detective work for you, giving you confidence whether you’re sorting pocket change or evaluating an inherited collection.
1999 Dime Value Guides
The 1999 Roosevelt dime was produced in four distinct varieties across three U.S. Mint facilities. Philadelphia and Denver struck business-strike coins at high speeds for everyday circulation, while San Francisco created special proof editions using highly polished dies and multiple strikes to capture every design detail.
The proof versions were sold exclusively in collector sets and never entered general circulation. San Francisco produced both a standard clad proof and a premium silver proof version, with the latter offering both numismatic appeal and precious metal content.

1999-P Dime Value
The Philadelphia Mint struck 2,164,000,000 Roosevelt dimes in 1999 — over two billion coins from a single mint in a single year. That enormous mintage anchors the coin’s market position permanently at the bottom.
Circulated 1999-P dimes are worth face value: 10 cents. Even a gem uncirculated MS65 example only brings about $7–$8. The PCGS auction record for a 1999-P regular strike stands at $3,738 — but that was an ANACS-graded MS65 sold at Heritage Auctions in April 2008, reflecting market conditions that no longer exist.
The real value threshold sits at MS68 and above, especially with the Full Bands (FB) designation. Full Bands means the two horizontal torch bands on the reverse show complete, unbroken separation — a strike quality indicator that is surprisingly rare even among billions of coins. According to PCGS population data, only a small number of 1999-P examples have been certified at MS68 FB or higher, making these coins genuinely scarce on a population basis.
A notable error type that has appeared on 1999-P coins is the missing clad layer — where one of the outer nickel layers is absent before striking, exposing the copper core. PCGS has certified a 1999-P with a missing obverse clad layer (PCGS Population: 1/334 at MS62 and below), and these coins typically sell for $50–$150 depending on grade and the prominence of the copper exposure.

1999-D Dime Value
The Denver Mint produced 1,397,750,000 Roosevelt dimes in 1999 — nearly 1.4 billion coins. Like its Philadelphia counterpart, the 1999-D is essentially a face-value coin in any circulated or typical uncirculated grade. An MS65 example brings just $5–$7 in today’s market.
What makes the 1999-D genuinely interesting is its Full Bands (FB) population data at the very top grades. According to PCGS census data, only 3 examples have been certified at MS69 Full Bands — with zero graded higher. At MS68 Full Bands, the count stands at approximately 90 coins (PCGS Population: 90/3). This extreme top-end scarcity turns what is otherwise a common coin into a true conditional rarity.
The MS69 Full Bands auction record is $1,800, set at Heritage Auctions in August 2023 — a result that confirms collector demand for this variety despite the coin’s modern date. The MS67 Full Bands population sits at 22 coins certified (PCGS: 22/93), making even that grade meaningfully scarce in the context of FB population.
For collectors not chasing top grades, circulated 1999-D dimes remain face value. MS65 examples cost $5–$7. This is the fundamental paradox of modern Roosevelt dimes: either you’re hunting the top 0.01% of survivors, or the coin remains just a coin.

1999-S DCAM Dime Value
The San Francisco Mint produced 2,543,401 clad proof Roosevelt dimes in 1999. These were sold exclusively in annual Proof Sets and never circulated. The DCAM designation — Deep Cameo (also written DC or Deep Cameo) — refers to the sharp contrast between frosted, matte-looking design elements and mirror-like background fields. This effect requires precisely prepared dies and careful planchet handling, and is the most desirable proof finish in the market.
DCAM is the top proof designation assigned by PCGS, equivalent to NGC’s “Ultra Cameo” label.
The 1999-S DCAM has experienced a significant market correction over two decades. At a Heritage Auctions sale in May 2002, a PR70 DCAM example sold for $1,438. By mid-2024, a coin of the same grade sold on eBay for approximately $150 — barely one-tenth of the earlier price.
The reason is straightforward: as more collectors have submitted coins over the years, the PR70 population has steadily grown, eroding the scarcity premium that once justified four-figure prices. PR69 examples now trade for just a few dollars to about $15 — not much above what a proof set break-out fetches without any grading slab.

1999-S Silver DCAM Dime Value
The 1999-S Silver DCAM proof had a mintage of 804,000 coins — more than three times lower than the regular clad proof. These were struck in 90% silver as part of the annual Silver Proof Set, making them the only 1999 dimes with any precious metal content. The current silver melt value for this coin is approximately $6.57, based on the coin’s 0.0723 troy oz silver weight.
The coin’s market trajectory tells a cautionary tale. In June 2003, a PR70 example sold at Heritage Auctions for $2,990. By early 2024, an NGC-certified PR69 DCAM sold at public auction for just $45 — essentially silver melt value.
This collapse happened because the graded coin market became much more efficient over time. As submissions multiplied and grading populations grew, the “rarity” premium that once existed at PR70 simply disappeared. PR69 coins now price primarily as “silver bars with collector packaging” rather than as rare numismatic items.
For the 1999-S Silver, PR65 examples are worth roughly $5.50 in today’s market, and even PR70s have limited upside over PR69 examples at current demand levels.

Rare 1999 Dime Error List
While billions of 1999 Roosevelt dimes were struck normally, a small number of minting errors escaped quality control. These errors range from subtle die doubling to dramatic wrong-metal strikes. The most dramatic examples command prices hundreds or even thousands of times their face value.
1. Broadstruck on Cent Planchet (Wrong Planchet Error)
This is the most spectacular and valuable 1999 dime error known. It happens when a dime die strikes a copper cent planchet (blank) without the collar die in place — the collar normally constrains the metal and keeps coins the right size and shape.
Without the collar, the coin spreads outward, becoming larger and thinner than a standard dime. Because cent planchets are made of zinc-coated copper rather than copper-nickel clad, metal mixing produces extraordinary surface colors: blue-green, violet, and gold-orange tones appear across both sides.
Only two examples have been documented for the 1999-D version. An MS65 Brown example graded by NGC sold for $6,325 at Heritage Auctions in mid-2015. A separate MS65 Brown example later sold for $14,375, establishing the current auction record for any 1999 dime.
A similar error also exists on 1999-P dimes — grading services have certified a 1999-P broadstruck coin at MS66 (NGC Census: 8/18), and these examples sell for significant premiums at auction.
2. Missing Clad Layer
This error type occurs when one of the outer nickel layers is absent from the planchet before the coin is struck. The result is a coin that shows copper on one side and the normal nickel-silver appearance on the other.
On 1999-P dimes, PCGS has certified at least one example with the obverse clad layer missing, graded MS62 (PCGS Population: 1/334 at that grade and below). This means the error is genuinely rare in certified form — not just unusual.
Missing obverse clad layer examples generally sell for more than missing reverse clad layers. Values typically range from $50 to $200 for Roosevelt dime examples, depending on grade and the prominence of the exposed copper. A 1999-D Roosevelt dime with missing obverse clad layer has also been certified at MS64 by PCGS and is documented by dealers.
3. Off-Center Strike
Off-center strikes occur when the planchet isn’t properly centered in the coin press at the moment of striking. Part of the design ends up missing, replaced by a flat, unstruck area of blank metal. The more off-center the strike, the higher the value.
On 1999 Roosevelt dimes, off-center errors ranging from about 10% to 30% off-center surface periodically in the market. Errors of 50% or more — where roughly half the design is missing but the date is still visible — are the most desirable to collectors.
A 1999-P dime struck approximately 15% off-center sold for around $45 in late 2023. Entry-level collectors often start with off-center strikes because they’re visually dramatic and more affordable than exotic wrong-metal errors.
4. Doubled Die Obverse (DDO)
Doubled die errors result from a misalignment during the die manufacturing process, where the working die receives multiple hub impressions at slightly different angles. The result is a visible second image on certain design elements — dates, lettering, or Roosevelt’s portrait features.

Coin Identifier and Value App

On 1999 Roosevelt dimes, minor doubled die obverse (DDO) varieties have been reported showing slight doubling on the date numerals or the inscription “LIBERTY.” These require magnification to confirm and are subtle compared to famous doubled dies like the 1955 Lincoln cent.
Minor DDO examples on 1999 dimes typically sell for $15–$30 uncertified when the doubling is clearly visible. More pronounced examples could bring higher premiums, especially if submitted for PCGS or NGC certification with an attribution.
5. Double Strike, Second Strike Off-Center
This dramatic error occurs when a coin receives a second strike from the dies while partially ejected from the collar. The result shows two overlapping impressions, with the second strike appearing partially off-center.
PCGS has documented a 1999-D dime with a double strike, second strike 95% off-center, graded MS64 Full Bands (PCGS Population: 3/192). This type of major mechanical error — where the coin is nearly fully outside the collar for the second strike — is extremely rare and commands substantial collector premiums.
A 1999-P dime with a D/S second strike 60% off-center has also been certified (PCGS Population: 5/326), representing a different variant of this error type.

FAQ About The 1999 Dime
1. How can I tell if my 1999 dime is valuable?
Most 1999 dimes in pocket change are worth only face value — 10 cents. To be worth significantly more, your coin needs to be in exceptional uncirculated condition (MS68 or higher), carry a Full Bands (FB) designation on the torch, or contain a verified mint error.
Start by checking the mint mark above the date on the obverse: P (Philadelphia), D (Denver), or S (San Francisco proof). If your coin shows unusual features — off-center design, copper coloring, or visible doubling — it could be a valuable error. Use the Coin Identifier and Value App to snap a photo and get an instant assessment.
2. What does “Full Bands” mean on a 1999 dime, and why does it matter?
Full Bands (FB) refers to the two horizontal lines crossing the torch bands on the reverse showing complete, unbroken separation with no weakness. Grading services PCGS and NGC assign this designation only when the bands meet their strict standards.
This is difficult to achieve during mass production, making FB coins substantially rarer than non-FB examples. For the 1999-D, only 3 coins are known at the MS69 FB grade (PCGS Population), and the MS69 FB auction record is $1,800 at Heritage Auctions in August 2023. That’s vs. about $5–$7 for a regular 1999-D MS65 — a dramatic difference driven entirely by strike quality.
3. What’s the difference between 1999-S proof dimes and regular circulation strikes?
The 1999-S dimes were made exclusively at the San Francisco Mint as proof coins for collectors, never for everyday use. Proof coins are struck multiple times with specially polished dies on specially prepared planchets, creating mirror-like fields and frosted design elements.
San Francisco made two proof versions: a standard clad proof (2,543,401 mintage) and a 90% silver proof (804,000 mintage). Regular P and D circulation dimes were mass-produced at high speed for commerce — over 3.5 billion combined. The visual difference is immediately obvious: proof coins look almost mirror-bright, while circulation strikes are comparatively dull.
4. Why did the 1999-S DCAM proof dime drop so much in value since 2002?
In May 2002, a PR70 DCAM sold for $1,438 at Heritage Auctions. By mid-2024, the same grade sold for around $150 on eBay. The crash happened because the certified coin market became more efficient over time.
As collectors submitted more coins, the PR70 population steadily grew — eroding the scarcity premium that once justified high prices. When PR70 was genuinely rare, it commanded large premiums. As the population expanded, prices collapsed. This is a well-documented pattern in modern proof coin markets.
5. Are there any 1999 dimes with a “No P” mint mark error?
No confirmed 1999 No-P Roosevelt dime errors are documented in major PCGS or NGC population reports. The most famous No-P Roosevelt dime is the 1982 No-P, which remains one of the series’ most popular varieties. For 1999, the mint mark appears correctly on all known circulation strikes from Philadelphia. If you believe you have a 1999 with a missing mint mark, professional examination by a third-party grading service like PCGS or NGC is essential before making any value claims.
6. What is the rarest 1999 dime error, and how much is it worth?
The rarest 1999 dime error is the 1999-D Broadstruck on a Cent Planchet (wrong planchet error). Only two examples are known worldwide, both graded MS65 Brown by NGC. One sold for $6,325 at Heritage Auctions in 2015, and another achieved $14,375 — the current all-time auction record for any 1999 dime. These coins display vivid blue-green, violet, and gold-orange surface colors caused by the mixing of zinc-coated copper cent metal during striking.
7. Is a 1999 dime made of silver?
Most 1999 dimes are not silver. The standard 1999-P and 1999-D circulation strikes are copper-nickel clad: an outer layer of 75% copper and 25% nickel over a pure copper core. The only silver 1999 dime is the 1999-S Silver Proof, struck in 90% silver as part of the annual Silver Proof Set. It contains 0.0723 troy ounces of silver, with a current melt value around $6.57. You can identify a 1999-S silver proof by its “S” mint mark and mirror-bright proof finish — it will never appear in circulation.
8. How does a 1999 dime missing clad layer error look, and what is it worth?
A missing clad layer error occurs when one of the outer nickel layers is absent from the planchet before striking. The coin appears copper on one side (the missing layer side) and the usual silver-white on the other. On 1999-P dimes, at least one certified example of the missing obverse clad layer exists (PCGS Population: 1/334 in MS62). Missing obverse clad layer dimes generally sell for $50–$200 depending on grade. A 1999-D missing obverse clad layer in MS64 has also been documented and listed by certified coin dealers.
9. What is the highest-graded 1999 dime ever certified by PCGS?
For the standard (non-FB) 1999-D, PCGS has graded examples up to MS69 in regular strike. For the 1999-D Full Bands, the top grade is MS69 FB with only 3 examples certified at that level (PCGS Population: 3/0, meaning none graded higher). For the 1999-P, the highest commonly seen grades are MS68 and MS68 FB. For proof coins, PR70 DCAM is the top designation, though population growth has significantly reduced the value premium for this grade compared to earlier years.
10. Should I clean my 1999 dime before selling or having it graded?
Never clean a coin before grading or selling. Cleaning — even with a soft cloth — removes microscopic surface metal and destroys the original luster that graders and collectors prize. A cleaned coin will be assigned a “details” grade by PCGS or NGC (such as “MS65 Details — Cleaned”), which dramatically reduces its value and market appeal. Uncleaned coins, even with small marks or minor toning, are always worth more than cleaned ones. Store your coins by the edges only, keep them in stable low-humidity conditions, and avoid PVC-containing holders, which release acids that cause irreversible green discoloration.
