Building a complete Mercury Dime collection 1916-1945 is one of the most rewarding goals in American numismatics – a full set of 77 silver coins spanning nearly three decades of history, from the tail end of World War I through the final days of World War II. These 90% silver dimes carry a face value of ten cents but command far more as collectibles, driven by iconic design, a legendary key date, and a collecting community that has treasured them for nearly a century.
Whether you are a seasoned silver stacker looking to add numismatic depth to your holdings or a newcomer drawn in by the beauty of Adolph Weinman’s design, this guide covers everything: history, specifications, key dates, pricing, and how to buy or sell your set with confidence.

The Story Behind the Mercury Dime
By 1916, the Liberty Head dime designed by Charles E. Barber had been circulating since 1892. U.S. Mint Director Robert W. Woolley decided it was time for a redesign and commissioned sculptor Adolph A. Weinman – a student of the legendary Augustus Saint-Gaudens – to create new designs for the dime, quarter, and half dollar simultaneously.
Weinman’s dime featured a youthful Liberty facing left, wearing a winged Phrygian cap. Americans almost immediately nicknamed it the “Mercury Dime” because the winged cap resembled the headwear associated with the Roman messenger god Mercury. The official name is the Winged Liberty Head Dime, and the design represents liberty of thought, not the deity. Weinman himself confirmed this distinction.
Production began at the Philadelphia Mint in late June 1916. The design ran unchanged through 1945, when the series ended and the Roosevelt Dime took its place. During the Great Depression, no dimes were struck in 1932 or 1933 – the mints concentrated resources on larger denominations. Those two years are simply absent from the series, not errors or missing pieces. A complete set skips them entirely.
Proof versions were struck from 1936 through 1942 at Philadelphia, but standard complete sets consist of circulation strikes only. Early 1916 coins carry a distinctive matte finish and slightly wider borders, setting them apart from later issues.
Design and Specifications of the Mercury Dime
The obverse shows Liberty in left profile, her winged cap inscribed with “LIBERTY,” “IN GOD WE TRUST” arching above the date, and “E PLURIBUS UNUM” curving to the right. Weinman’s rumored model was Elsie Stevens, wife of poet Wallace Stevens, though this was never confirmed.
The reverse centers a fasces – an ancient Roman symbol of authority consisting of a bundle of rods bound with an olive branch – flanked by stars, with “UNITED STATES OF AMERICA” above and “ONE DIME” below. The olive branch represents peace; the fasces represents civic strength.
| Specification | Detail |
|---|---|
| Composition | 90% silver, 10% copper |
| Weight | 2.50 grams (38.58 grains) |
| Diameter | 17.9 mm |
| Edge | Reeded |
| Silver Content | 0.0723 troy oz per coin |
| Mints | Philadelphia (no mark), Denver (D), San Francisco (S) |
One detail collectors prize above most others: Full Bands (FB). The horizontal bands crossing the fasces on the reverse are often weakly struck, leaving them flat and indistinct. Coins where these bands are fully separated and sharply defined carry the FB or FSB designation and command significant premiums – sometimes 20 to 50 percent above comparable non-FB examples. This applies across virtually every date in the series.
The Complete Mercury Dime Collection: 77 Coins Across Three Mints
A complete Mercury Dime collection 1916-1945 contains 77 date-and-mintmark combinations. Standard album holders like Whitman folders and Dansco albums are designed with exactly 77 slots across three pages, making them ideal for organizing a full set.
The three mints – Philadelphia, Denver, and San Francisco – each produced coins in most years, though not every mint struck dimes every year. Philadelphia issues carry no mintmark. Denver coins show a “D” and San Francisco issues show an “S,” both located on the reverse to the left of the fasces.

Key Dates and Rarities That Define the Set
Every complete Mercury Dime collection rises or falls on a handful of key dates. These are the coins that separate a true complete set from a partial one.
1916-D – The King of the Series
The 1916-D is the coin every Mercury Dime collector talks about. Only 264,000 were struck at the Denver Mint – compared to over 22 million from Philadelphia that same year. Collectors began hunting it in the 1930s and found almost none in circulation. Today it anchors every serious set.
In Good to Very Good condition, expect to pay $1,100 to $1,600. In Mint State grades (MS60 to MS65), values range from roughly $15,000 to $30,000 or more. MS66 and above examples have sold for $50,000 and higher at major auctions. For any key date this significant, buying a coin graded and slabbed by PCGS or NGC is strongly advised.
Other Keys and Semi-Keys
- 1921 (Philadelphia): Low mintage from a post-WWI recession. Affordable in circulated grades but scarce in Mint State.
- 1921-D: Around 1.08 million struck. A step up from the 1916-D in accessibility but still a genuine key. Circulated examples run $15 to $25; Mint State coins climb to $200 to $500.
- 1926-S: A semi-key with relatively low mintage. Watch condition carefully – many are heavily worn.
- 1942/41 Overdate (Philadelphia): A dramatic variety where a 1942 die was punched over a 1941 die. Visible under magnification. Circulated examples run $20 to $40; higher grades reach $500 to $2,000.
- 1942/41-D Overdate (Denver): The Denver version of the same variety. Equally collectible, often slightly scarcer in sharp grades.

Mercury Dime Values: What Does a Complete Set Cost?
Silver’s current spot price sits at $77 per troy ounce. Each Mercury Dime contains 0.0723 oz of pure silver, putting the melt value of a single coin at roughly $5.57. A full 77-coin set holds about 5.57 oz of silver – a melt floor of around $429. But collectible premiums far exceed melt for virtually every coin in the series.
Here is how pricing breaks down by grade and type:
| Coin Type | Circulated (G-VF) | Uncirculated (MS60+) | FB Premium |
|---|---|---|---|
| Common dates (e.g., 1945-P) | $5-$15 | $10-$30 | +20-50% |
| Semi-key dates | $20-$100 | $100-$500 | +20-50% |
| 1921-D | $15-$25 | $200-$500 | Significant |
| 1916-D | $1,100-$4,500+ | $15,000-$50,000+ | Extreme |
A starter complete set in low circulated grades – including a rough 1916-D – typically runs $1,000 to $1,500 when assembled patiently through coin shows and auctions. A high-end set in MS65 with Full Bands throughout can reach $20,000 to $100,000 or more, depending on the condition of the key dates.

Collecting Strategies: Building Your Set Intelligently
Buy the high-mintage 1940s dates first. These run $5 to $15 each in circulated grades and are plentiful at coin shows and shops.
Work through the 1921, 1926-S, and other low-mintage dates as budget allows. Buy the best condition you can afford.
Check dates like 1942 and 1942-D under magnification for overdate varieties. A loupe or 10x jeweler’s glass is enough to spot them.
Treat it as the capstone. Buy it slabbed by PCGS or NGC. A raw 1916-D carries real risk of being altered, cleaned, or misidentified.
Replace worn coins with sharper examples. Full Bands designations add value and visual appeal across the whole set.
Where to Buy Mercury Dimes
Coin shows offer the best hands-on experience – you can examine coins before buying. Major auction houses like Stack’s Bowers handle high-grade and key-date material. For raw circulated coins, local coin shops and estate sales can yield good finds at fair prices.
For key dates, always prioritize PCGS or NGC slabbed coins. The 1916-D is heavily counterfeited – altered mintmarks from 1916-P coins are the most common fake. A slab removes that risk entirely.
Storage and Preservation
Dansco and Whitman albums protect Mercury Dimes well and display them attractively. Avoid PVC-based plastic flips – they leach chemicals that cause green haze on silver over time. Store your collection in a cool, dry environment away from humidity and direct sunlight. For high-value slabbed coins, a dedicated safe or safety deposit box is worth considering.
Common Misconceptions About Mercury Dimes
“It depicts the Roman god Mercury.” It does not. The winged cap is a Phrygian cap – a classical symbol of liberty. Weinman designed it to represent freedom of thought, and the official name is the Winged Liberty Head Dime.
“The 1932 and 1933 gaps make a set impossible to complete.” No Mercury Dimes were struck in those years. A complete set of 77 coins skips them entirely by definition – their absence is not a flaw.
“All Mercury Dimes are rare.” The opposite is true for most dates. High-mintage 1940s issues turn up in coin jars and estate lots regularly. Only six key and semi-key dates drive real scarcity.
“You need proofs to have a complete set.” Standard complete sets consist of circulation strikes only. Proofs are a separate collecting category.
“The matte finish on 1916 coins is an error.” It is a normal characteristic of first-year production. These coins are actually sought after for that distinctive look.
“A complete set costs a fortune.” In circulated grades, a patient collector can assemble a full 77-coin set – including a low-grade 1916-D – for $1,000 to $1,500. It takes time, but it is achievable.
Selling a Mercury Dime Collection: What to Know
If you already own a partial or complete Mercury Dime set and are considering selling, a few factors determine what you will receive.
Grade matters most. A Full Bands MS65 example of a common date is worth multiples of a heavily worn circulated coin. Have key dates graded by PCGS or NGC before selling if they are not already slabbed – the premium for a certified key date over a raw one is often substantial.
Know your audience. Mercury Dime sets sell best to collectors who understand their value. Generic silver buyers will offer melt or close to it. A numismatic dealer or auction house will recognize and pay for the collector premium.
Partial sets still have value. Even without the 1916-D, a near-complete set in solid grades is attractive to buyers who already own the key date and want to fill the rest quickly.

Frequently Asked Questions
How many coins are in a complete Mercury Dime collection?
A complete set contains 77 date-and-mintmark combinations from the Philadelphia, Denver, and San Francisco mints, spanning 1916 to 1945. No dimes were minted in 1932 or 1933, so those years are absent from every complete set.
What is the rarest Mercury Dime?
The 1916-D is the key date of the series. Only 264,000 were struck at the Denver Mint, making it dramatically scarcer than any other issue. Even in heavily worn condition it sells for over $1,000, and Mint State examples regularly reach $15,000 to $30,000 or more.
What does Full Bands (FB) mean on a Mercury Dime?
Full Bands refers to the horizontal bands on the fasces on the reverse being fully separated and sharply struck. Many Mercury Dimes have weakly struck bands. Coins with the FB designation command premiums of 20 to 50 percent or more over non-FB examples of the same date and grade.
How much silver is in a Mercury Dime?
Each Mercury Dime is 90% silver and contains 0.0723 troy ounces of pure silver. At the current spot price of $77 per ounce, the melt value of a single coin is approximately $5.57. A full 77-coin set contains about 5.57 oz of silver with a melt floor around $429.
How do I avoid buying a fake 1916-D Mercury Dime?
The most common fake is a 1916 Philadelphia coin with an added or altered "D" mintmark. Always buy the 1916-D in a PCGS or NGC slab from a reputable dealer. The cost of professional grading is far less than the risk of buying a counterfeit.
What is a good starting budget for building a Mercury Dime set?
You can begin with common 1940s dates for $5 to $15 each in circulated grades. A complete set in low circulated grades – including a rough 1916-D – typically runs $1,000 to $1,500 when assembled over time. High-grade sets with Full Bands designations cost significantly more.
Can I sell a partial Mercury Dime set?
Yes. Partial sets, individual key dates, and even common-date Mercury Dimes all have buyers. A numismatic dealer will pay closer to full collector value than a generic silver buyer. Contact Accurate Precious Metals to discuss what your set is worth – visit us in Salem, Oregon or use our mail-in service from anywhere in the U.S.
Were any Mercury Dimes made in proof?
Yes. Proof Mercury Dimes were struck at the Philadelphia Mint from 1936 through 1942. These are low-mintage, highly polished collector coins. They are not part of a standard complete circulation-strike set but are collected separately or added as a bonus to advanced sets.
