Quick Answer: Most common-date Mercury dimes in circulated condition are worth $2–$5 for their silver content alone. Key dates like the 1916-D ($800–$50,000+), 1921 ($40–$3,000+), and 1921-D ($50–$4,500+) command serious premiums. The coveted "Full Bands" (FB) designation on the reverse fasces can multiply a coin's value 2x–10x or more across the entire series. Mercury dimes contain 90% silver (0.07234 troy oz), giving every coin a base melt value tied to the silver spot price.
The Mercury dime — officially the Winged Liberty Head dime — is one of the most beloved and widely collected coins in American numismatics. Designed by sculptor Adolph A. Weinman and minted from 1916 to 1945, it features a portrait of Liberty wearing a winged Phrygian cap (symbolizing freedom of thought, not the Roman god Mercury) on the obverse and a Roman fasces wrapped with an olive branch on the reverse. The coin replaced the Barber dime and was itself replaced by the Roosevelt dime in 1946. With 30 years of production across three mint facilities, the series offers collectors an appealing mix of affordable common dates, genuinely scarce key dates, and the added dimension of silver content that provides a built-in floor value for every coin.
Mercury Dime Design and Specifications
Adolph A. Weinman won a design competition in 1916 that also awarded him the Walking Liberty half dollar contract. His model for the obverse of the dime was Elsie Stevens, wife of poet Wallace Stevens. The reverse features a fasces — a bundle of rods bound around an axe — symbolizing strength through unity, wrapped with an olive branch representing peace.

The "Full Bands" Premium
The horizontal bands on the fasces (reverse) are one of the weakest strike points on Mercury dimes. On most coins, these bands are partially merged or indistinct. When a coin shows complete, fully separated horizontal bands across both the upper and lower sets, it receives the "Full Bands" (FB) designation from PCGS or the "Full Split Bands" (FSB) designation from NGC. This distinction can multiply a coin's value dramatically — sometimes by 5x–10x or more compared to a non-FB example of the same date and grade.
Mercury Dime Value Chart: Common Dates
The majority of Mercury dimes from the late 1920s through the 1940s are common dates. Even so, every Mercury dime carries a silver premium above face value.
| Grade | Value Range (Non-FB) | Value Range (Full Bands) |
|---|---|---|
| Good (G-4) | $2–$4 | N/A (wear too heavy for FB) |
| Very Good (VG-8) | $3–$5 | N/A |
| Fine (F-12) | $3–$6 | N/A |
| Very Fine (VF-20) | $4–$8 | N/A |
| Extremely Fine (EF-40) | $6–$12 | $10–$20 |
| About Uncirculated (AU-50) | $10–$18 | $15–$30 |
| Uncirculated (MS-60) | $15–$30 | $25–$55 |
| Choice Uncirculated (MS-63) | $20–$45 | $35–$80 |
| Gem Uncirculated (MS-65) | $35–$75 | $60–$200 |
| Superb Gem (MS-66+) | $60–$150 | $100–$500+ |
These values apply to dates like 1940, 1941, 1942, 1943, 1944, and 1945 from all three mints. Philadelphia issues tend to have the strongest strikes, with Full Bands examples most readily available from that mint.
Key Date Mercury Dime Values
Key dates are the coins that drive serious collector interest and represent the best long-term investment potential in the series. Low mintages, poor survival rates, and consistent demand make these coins genuinely scarce.
1916-D Mercury Dime Value
The 1916-D is the undisputed king of Mercury dimes and one of the most famous key dates in all of U.S. coinage. With a mintage of only 264,000 coins — the lowest in the series by a wide margin — this first-year Denver Mint issue is a cornerstone rarity.
| Grade | Value Range |
|---|---|
| About Good (AG-3) | $800–$1,200 |
| Good (G-4) | $1,200–$1,800 |
| Very Good (VG-8) | $1,800–$2,800 |
| Fine (F-12) | $2,800–$4,500 |
| Very Fine (VF-20) | $4,500–$7,000 |
| Extremely Fine (EF-40) | $6,500–$10,000 |
| About Uncirculated (AU-50) | $9,000–$14,000 |
| Uncirculated (MS-60) | $12,000–$18,000 |
| Choice Uncirculated (MS-63) | $18,000–$30,000 |
| Gem Uncirculated (MS-65) | $40,000–$70,000+ |
| MS-65 Full Bands | $80,000–$150,000+ |
In 2024, a 1916-D Mercury dime graded MS-67 FB sold for over $300,000 at Heritage Auctions. Authentication is essential because altered mint marks (adding a "D" to the much more common 1916 Philadelphia issue) are among the most frequently encountered fakes in numismatics.
How to Authenticate a 1916-D Mercury Dime
Because of the enormous price gap between the 1916 (no mint mark) and the 1916-D, counterfeits and altered coins are extremely common. Here's what to look for:
- Mint mark position: The genuine "D" sits between the bottom of the olive branch and the "E" in "ONE" on the reverse. Study known genuine examples
- Mint mark style: The Denver "D" has specific font characteristics for 1916 — the letter should not look tooled, with natural flow into the coin's field
- Surface texture: Added mint marks often disturb the surrounding field, leaving tooling marks, unnatural surfaces, or differences in luster
- Die diagnostics: Genuine 1916-D examples share specific die markers that experts use for confirmation
- Professional grading: Always insist on PCGS or NGC certification for any purported 1916-D Mercury dime
1921 Mercury Dime Value
After a three-year hiatus (1918–1920 at Philadelphia, though dimes were struck in 1919 and 1920), the 1921 Philadelphia issue has a low mintage of 1,230,000 and high attrition due to the economic boom of the early 1920s. Survivors in high grades are genuinely scarce.
| Grade | Value Range |
|---|---|
| Good (G-4) | $40–$70 |
| Very Good (VG-8) | $65–$100 |
| Fine (F-12) | $100–$175 |
| Very Fine (VF-20) | $200–$350 |
| Extremely Fine (EF-40) | $350–$550 |
| About Uncirculated (AU-50) | $500–$800 |
| Uncirculated (MS-60) | $700–$1,100 |
| Choice Uncirculated (MS-63) | $1,100–$1,800 |
| Gem Uncirculated (MS-65) | $2,500–$4,500+ |
| MS-65 Full Bands | $5,000–$12,000+ |
1921-D Mercury Dime Value
The 1921-D is another major key date with a mintage of 1,080,000. Like the Philadelphia issue, few were saved in high grade. This coin is notoriously weakly struck, making Full Bands examples exceptionally rare and valuable.
| Grade | Value Range |
|---|---|
| Good (G-4) | $50–$80 |
| Very Good (VG-8) | $75–$130 |
| Fine (F-12) | $150–$250 |
| Very Fine (VF-20) | $250–$400 |
| Extremely Fine (EF-40) | $400–$650 |
| About Uncirculated (AU-50) | $600–$1,000 |
| Uncirculated (MS-60) | $900–$1,500 |
| Choice Uncirculated (MS-63) | $1,500–$2,500 |
| Gem Uncirculated (MS-65) | $3,500–$6,500+ |
| MS-65 Full Bands | $8,000–$20,000+ |
1926-S Mercury Dime Value
The 1926-S has a mintage of 1,520,000 and is one of the most condition-sensitive coins in the series. Examples in grades above Very Fine are scarce, and gem examples with Full Bands are major rarities.
| Grade | Value Range |
|---|---|
| Good (G-4) | $8–$14 |
| Very Good (VG-8) | $10–$20 |
| Fine (F-12) | $25–$50 |
| Very Fine (VF-20) | $75–$150 |
| Extremely Fine (EF-40) | $250–$500 |
| About Uncirculated (AU-50) | $700–$1,200 |
| Uncirculated (MS-60) | $1,200–$2,000 |
| Choice Uncirculated (MS-63) | $2,000–$3,500 |
| Gem Uncirculated (MS-65) | $5,000–$10,000+ |
Complete Mercury Dime Value by Year
1916–1919: The Early Years
The first years of production include the legendary 1916-D as well as several semi-key dates. Strikes vary considerably during this period as the Mint adjusted die preparation.
| Date | Mint | Mintage | G-4 | VF-20 | MS-63 |

1920–1929: The Scarce Decade
The 1920s produced several of the series' key and semi-key dates. Branch mint issues — particularly from San Francisco — are consistently scarce in higher grades. The years 1921 and 1921-D are the standout rarities.
| Date | Mint | Mintage | G-4 | VF-20 | MS-63 |

Note: No Mercury dimes were struck in 1922.
1930–1939: Depression Era
Production was sharply curtailed during the Great Depression, with no dimes minted in 1932 or 1933. The coins from this decade tend to be well-preserved because many were saved during the economic crisis rather than circulated. However, several dates have genuinely low mintages.
| Date | Mint | Mintage | G-4 | VF-20 | MS-63 |
|---|---|---|---|---|---|
| 1930 | P | 6,770,000 | $3–$5 | $6–$12 | $30–$55 |

| 1939-S | S | 10,540,000 | $3–$4 | $4–$7 | $16–$28 |
1940–1945: The War Years
The final years of Mercury dime production saw massive mintages driven by wartime economic expansion. These coins are the most affordable in the series, though Full Bands examples still command premiums. The famous 1942/1 overdate varieties emerged during this period.
| Date | Mint | Mintage | G-4 | VF-20 | MS-63 |
|---|---|---|---|---|---|
| 1940 | P | 65,361,827 | $2–$3 | $3–$4 | $10–$16 |

The 1942/1 Overdate: Mercury Dime's Most Famous Error
The 1942/1 overdate exists in both Philadelphia and Denver mint versions. These dramatic errors occurred when 1942-dated dies were punched over 1941-dated hubs, leaving clear traces of the underlying "1" beneath the "2" in the date.
1942/1 Philadelphia Overdate Value
| Grade | Value Range |
|---|---|
| Good (G-4) | $350–$500 |
| Very Good (VG-8) | $450–$650 |
| Fine (F-12) | $550–$800 |
| Very Fine (VF-20) | $700–$1,100 |
| Extremely Fine (EF-40) | $1,000–$1,600 |
| About Uncirculated (AU-50) | $1,500–$2,500 |
| Uncirculated (MS-60) | $2,500–$4,000 |
| Choice Uncirculated (MS-63) | $4,000–$7,000 |
| Gem Uncirculated (MS-65) | $10,000–$20,000+ |
1942/1-D Denver Overdate Value
The Denver mint version is scarcer than the Philadelphia issue and commands higher prices across all grades.
| Grade | Value Range |
|---|---|
| Good (G-4) | $400–$600 |
| Very Good (VG-8) | $500–$750 |
| Fine (F-12) | $650–$1,000 |
| Very Fine (VF-20) | $900–$1,400 |
| Extremely Fine (EF-40) | $1,200–$2,000 |
| About Uncirculated (AU-50) | $2,000–$3,500 |
| Uncirculated (MS-60) | $3,500–$5,500 |
| Choice Uncirculated (MS-63) | $5,500–$9,000 |
| Gem Uncirculated (MS-65) | $15,000–$30,000+ |
Professional authentication by PCGS or NGC is essential. The overdate is visible under moderate magnification and becomes increasingly apparent in higher grades where less wear has obscured the underlying digit.
Other Valuable Mercury Dime Errors and Varieties
| Error/Variety | Dates | Value Range |
|---|---|---|
| 1942/1 Overdate (P) | 1942 | $350–$20,000+ |
| 1942/1-D Overdate | 1942-D | $400–$30,000+ |
| 1945-S Micro S | 1945-S | $3–$50+ |
| Doubled Die Obverses | Various | $25–$2,000+ |
| Repunched Mint Marks | Various | $5–$200+ |
| Off-Center Strikes (10–50%) | Various | $25–$500+ |
| Broadstrikes (no collar) | Various | $30–$250 |
| Clipped Planchets | Various | $10–$100 |
| Die Cuds (major) | Various | $25–$300+ |
| Wrong Planchet Strikes | Various | $500–$5,000+ |
The 1945-S Micro S Variety
In 1945, the San Francisco Mint used a smaller-than-normal "S" mint mark punch on some dies. The resulting "Micro S" variety is identifiable by comparing the size of the mint mark to a normal 1945-S. While not a major rarity, it's a popular variety that commands a modest premium.
Silver Content and Melt Value
Every Mercury dime contains 0.07234 troy ounces of pure silver. This gives each coin a base "melt value" that fluctuates with the silver spot price — an important consideration when buying or selling common dates.
| Silver Spot Price | Mercury Dime Melt Value |
|---|---|
| $20/oz | $1.45 |
| $25/oz | $1.81 |
| $30/oz | $2.17 |
| $35/oz | $2.53 |
| $40/oz | $2.89 |
| $50/oz | $3.62 |
At current silver prices, even heavily worn common-date Mercury dimes carry a meaningful silver premium over their 10-cent face value. For bulk purchases of common dates, dealers typically price Mercury dimes based on silver content plus a small collector premium.
How to Grade Mercury Dimes
Accurate grading is essential for determining value. The Sheldon scale runs from 1 to 70, with specific grade points carrying particular significance for Mercury dimes.
Key Wear Points
- Hair above ear/wing: The highest point on the obverse. This area shows friction first and is the primary obverse grading focal point
- Hair braid: The diagonal band of hair crossing Liberty's face shows progressive wear in lower grades
- Wings on cap: The feathers on the Phrygian cap flatten with circulation
- Fasces bands (reverse): The horizontal bands that determine the Full Bands designation — these also serve as wear indicators
- Diagonal bands on fasces: Show progressive flattening in circulated grades
- Date: Mercury dime dates are well-protected compared to buffalo nickels, but heavy wear can still affect readability on very low-grade coins
Quick Grading Reference
| Grade | What to Look For |
|---|---|
| About Good (AG-3) | Outline of Liberty visible, date readable, most detail worn smooth |
| Good (G-4) | Liberty's outline clear, date and "LIBERTY" readable, rim intact, reverse flat |
| Very Good (VG-8) | Some wing feather detail visible, hair braid partially defined |
| Fine (F-12) | Half of wing feathers visible, diagonal bands on fasces partially defined |
| Very Fine (VF-20) | Most wing feathers visible with some flatness, hair braid distinct |
| Extremely Fine (EF-40) | All feathers sharp with light wear on highest points, diagonal bands nearly complete |
| About Uncirculated (AU-50) | Trace wear on hair above ear and on fasces bands only, substantial luster |
| Uncirculated (MS-60+) | No wear; graded by luster, strike quality (especially bands), and contact marks |
Understanding Full Bands
The Full Bands designation applies only to uncirculated coins (MS-60 and above). To qualify, both sets of horizontal bands on the reverse fasces must show complete, unbroken separation. This is a strike characteristic, not a wear issue — many uncirculated Mercury dimes were simply not struck with enough pressure to fully bring up these delicate details.
Key factors affecting strike quality:
- Mint of origin: Philadelphia generally produced the best strikes; San Francisco and Denver coins are more frequently weakly struck
- Die state: Early die state coins tend to show fuller strikes than late die state coins
- Date: Some years are notoriously weak in the bands area regardless of mint
- Planchet quality: Well-prepared planchets helped produce sharper strikes
Mercury Dime Collecting Strategies
Strategy 1: One Per Year (Budget-Friendly)
Collect one Mercury dime for each year minted (1916–1945, excluding 1922, 1932, and 1933). This approach requires roughly 27 coins and can be completed in Good to Very Good condition for $200–$400, substituting a 1916 Philadelphia for the impossible-to-afford 1916-D.
Strategy 2: Complete by Date and Mint Mark
A full date-and-mint-mark set comprises approximately 77 coins. In circulated grades (Good to Fine), expect to spend $3,000–$8,000. The 1916-D will account for 50% or more of the total cost, and the 1921 and 1921-D will represent most of the remainder.
Strategy 3: Key Dates Only
Focus on the coins with the strongest investment track record: the 1916-D, 1921, 1921-D, 1926-S, 1931-D, and the 1942/1 overdates. Buy the best grade you can afford and always insist on PCGS or NGC certification for coins valued over $100.
Strategy 4: Full Bands Challenge
For the advanced collector, assembling a set of FB Mercury dimes — even limited to common dates — is a rewarding pursuit. Some dates are virtually unobtainable in FB, making a complete FB set one of the most challenging goals in 20th-century numismatics.
Estimated Budget by Completion Level
| Collection Goal | Estimated Cost |
|---|---|
| One per year, any mint, G-4 (minus 1916-D) | $200–$400 |
| Complete by date/mint, G-4 | $3,000–$8,000 |
| Complete by date/mint, VF-20 | $10,000–$25,000 |
| Complete by date/mint, MS-63 | $40,000–$100,000+ |
| Complete by date/mint, MS-65 FB | $200,000–$500,000+ |
Where to Buy Mercury Dimes

Estate Sales and Inherited Collections
Mercury dimes are among the most commonly found coins in inherited collections. They're small and easy to overlook in jars or bags of old coins. If you've inherited a collection, sort by date and mint mark first — you might have a 1916-D, 1921, or 1942/1 overdate hiding in the mix. CoinID can instantly identify each coin from a photo, saving you hours of manual sorting and giving you current market values.
Mercury Dime Investment Outlook
Mercury dimes have been one of the most consistently performing areas of U.S. numismatics over the past several decades. The combination of silver content (providing a floor value), an iconic design, and genuine scarcity in key dates creates strong long-term demand.
Factors that support long-term value:
- Silver content: Every coin contains 0.07234 oz of pure silver, providing a built-in minimum value
- Iconic design: Consistently rated as one of the most beautiful U.S. coin designs ever produced
- Broad collector base: Attracts type collectors, series specialists, and silver stackers
- Full Bands premium: Creates a secondary collecting challenge that sustains demand for well-struck examples
- Finite supply: No more will ever be made, and high-grade examples are absorbed into permanent collections
- Crossover appeal: Popular with both coin collectors and precious metals investors
Frequently Asked Questions
How much is a Mercury dime worth?
Most common-date Mercury dimes in circulated condition are worth $2–$5, primarily based on their silver content (0.07234 oz of pure silver). Key dates like the 1916-D ($1,200+ in Good condition), 1921 ($40+), and 1921-D ($50+) are worth significantly more. The Full Bands designation on uncirculated coins can multiply values considerably.
What is the most valuable Mercury dime?
The most valuable Mercury dime is the 1916-D in gem condition with Full Bands. A 1916-D graded MS-67 FB sold for over $300,000 at auction. For non-key dates, Full Bands examples in superb gem grades can reach $500–$5,000+ depending on the scarcity of the date in FB.
How can I tell if my Mercury dime has Full Bands?
Examine the reverse under magnification (at least 5x). Look at the horizontal bands crossing the vertical rods of the fasces. On a Full Bands coin, both the upper and lower sets of horizontal bands must show complete, unbroken separation. If the bands merge or blend together in any spot, the coin does not qualify for the FB designation.
Where is the mint mark on a Mercury dime?
The mint mark is on the reverse, to the left of the fasces at the bottom of the coin, near the base of the olive branch. "D" indicates Denver, "S" indicates San Francisco, and no mint mark means Philadelphia. On the 1916-D, the mint mark position and style are critical for authentication.
Is a Mercury dime really silver?
Yes. Mercury dimes are composed of 90% silver and 10% copper, containing exactly 0.07234 troy ounces of pure silver. This gives every Mercury dime a built-in "melt value" based on the current silver spot price. At $30/oz silver, each coin is worth approximately $2.17 in silver content alone.
What year Mercury dimes are most valuable?
The most valuable dates are the 1916-D (264,000 mintage), 1921 (1,230,000), 1921-D (1,080,000), 1926-S (1,520,000), and the 1942/1 overdates (both Philadelphia and Denver). The 1931-D (1,260,000) is also a semi-key date. Full Bands examples of any date can command substantial premiums.
Should I clean my Mercury dime?
Never clean a Mercury dime. Cleaning removes the natural patina (toning) that develops over decades and damages the coin's surface at a microscopic level. Cleaned coins are worth 50–75% less than original, uncleaned examples. Certified grading services label cleaned coins as "Details" grades, which significantly reduces their market value.
How do I tell if my 1942 dime is an overdate?
Look at the "2" in the date under magnification (10x or higher). On a genuine 1942/1 overdate, you'll see traces of a "1" beneath and slightly to the right of the "2." The top of the "1" often protrudes above the "2." Both Philadelphia and Denver mint versions exist. Professional authentication is strongly recommended for any coin you suspect is an overdate.
Are Mercury dimes a good investment?
Mercury dimes have historically been strong performers, particularly key dates in certified high grades and Full Bands examples. The series benefits from the dual appeal of numismatic value and precious metal content. Common-date Mercury dimes in circulated grades are a popular way to accumulate physical silver at modest premiums over melt value.
Conclusion
The Mercury dime series (1916–1945) offers one of the most rewarding collecting experiences in American numismatics. From affordable common dates that carry silver value to five- and six-figure rarities like the 1916-D in gem condition, there's a place for every budget. The Full Bands dimension adds a layer of challenge and reward that keeps advanced collectors engaged for years. Whether you're sifting through an inherited jar of old coins, strategically building a date-and-mint set, or hunting for that elusive Full Bands specimen, having the right identification tools saves time and prevents costly mistakes. Use CoinID to instantly identify your Mercury dimes, check for key dates and varieties, and get current market values — just snap a photo and let the app do the work.
