If you collect American coins, the 1916-D Mercury Dime needs no introduction. It is the key date of the entire Mercury Dime series, one of the most counterfeited coins in American numismatics, and a coin that commands serious money in any grade. At Clemson Coins, Currency, Bullion and Jewelry in Pendleton, SC, we buy Mercury Dimes regularly, and the 1916-D is always a coin we are excited to see come through the door.
The Mercury Dime Series
The Mercury Dime, officially called the Winged Liberty Head Dime, was designed by sculptor Adolph A. Weinman and struck from 1916 through 1945. Weinman also designed the Walking Liberty Half Dollar, which was introduced the same year, making 1916 one of the most artistically significant years in American coinage history.
The obverse features a portrait of Liberty wearing a winged cap, which many people mistook for the Roman god Mercury, giving the coin its popular nickname. The wings on the cap are meant to symbolize freedom of thought. The reverse features a fasces, a bundle of rods bound around an axe that was a Roman symbol of authority and civic strength, flanked by an olive branch representing peace.
The design is widely considered one of the most beautiful in American coinage. The detail is exceptional, the composition is balanced, and the symbolism is layered in a way that rewards close examination. Weinman's Mercury Dime and Walking Liberty Half Dollar represent the high point of American coin design in the early twentieth century.
Why 1916-D Is the Key Date
The Mercury Dime was introduced in October 1916, replacing the Barber Dime that had been in production since 1892. Because production began late in the year, mintages at all three mints were low. Philadelphia struck 22,180,080 dimes. San Francisco struck 10,450,000. Denver struck only 264,000.
That Denver mintage of 264,000 is what makes the 1916-D the key date of the series. To put it in perspective, the next lowest mintage in the entire Mercury Dime series is the 1921 at 1,230,000, nearly five times as many. The 1916-D is not just a key date. It is in a category by itself.
Of those 264,000 coins, many were spent in circulation over the following decades. The coin was not recognized as a rarity immediately, which means many examples were worn down to Good or Very Good condition before collectors began setting them aside. Today, PCGS and NGC combined have certified roughly 12,000 to 15,000 examples, and the vast majority are in circulated grades. Mint State examples are genuinely rare, and high-grade Mint State examples are among the most coveted coins in American numismatics.
The Design: What to Look For
Obverse: Liberty faces left, wearing a winged Phrygian cap. The portrait is detailed and graceful, with Liberty's hair flowing back beneath the cap. LIBERTY appears above, IN GOD WE TRUST appears to the left, and the date appears at the right.
Reverse: A fasces, the bundle of rods and axe, dominates the center of the reverse. An olive branch wraps around the left side of the fasces. The inscriptions UNITED STATES OF AMERICA and ONE DIME appear around the rim, with E PLURIBUS UNUM above the fasces. The mint mark is to the right of the word ONE and to the lower left of the fasces.
The Full Bands designation, abbreviated FB on certified coins, refers to the horizontal bands that bind the fasces on the reverse. On a fully struck coin, these bands show complete separation across their full width. Full Bands examples command significant premiums because the bands are one of the first areas to show weakness in the strike, and a coin with complete, separated bands represents the best of what the Mercury Dime series has to offer.
How to Authenticate a 1916-D Mercury Dime
The 1916-D Mercury Dime is one of the most counterfeited coins in American numismatics. There are two primary types of fakes you will encounter, and every collector needs to know how to identify them.
Detecting a counterfeit 1916-D Mercury Dime typically involves a combination of six primary methods ranging from visual diagnostics to metallurgical tests. Because added mint marks on common 1916 Philadelphia dimes are highly common, expert grading is the ultimate standard.
Primary ways to authenticate the coin include:
- Mint Mark Placement: The D mint mark is located on the reverse, to the right of the word ONE. It must match the exact shape and position of known genuine dies. Authentic mint marks are boxy, with well-defined serifs and a triangular interior.
- Repunched Mint Mark Diagnostics: Only four reverse dies were used to strike genuine 1916-D dimes. Two of these feature a clearly visible repunched mint mark (RPM), leaving a notched effect on the upper-left serif of the D.
- Die Rotation Check: Genuine 1916-D dimes exhibit a distinct die rotation. If you hold the obverse at 3 o'clock and 9 o'clock and flip it over to check the reverse, the back of the coin should be rotated to approximately the 11 o'clock position.
- Weight and Dimensions: Authentic Mercury Dimes weigh exactly 2.5g and have a diameter of 17.9mm. Deviations in weight or thickness indicate a counterfeit. However, this is not always accurate as normal wear slightly reduces those measurements.
- Metallurgical and Sound Testing: For complete counterfeits made of the wrong alloy, the ping test (genuine silver rings distinctly, while base metals produce a dull thud) and the magnet test (silver is non-magnetic) provide quick initial screening.
- Third-Party Professional Grading: Due to the coin's high value, the most reliable way to prevent fraud is to rely on authentication by major grading services like PCGS, NGC and CACG.
The Added Mint Mark
The most common fake is a genuine 1916 Philadelphia dime with a D mint mark added. The Philadelphia 1916 dime had a mintage of over 22 million, making it common and inexpensive. A counterfeiter takes one of these common coins and adds a D mint mark to create the appearance of a 1916-D.
On a genuine coin, the mint mark sits naturally in the field with no disturbance around it. The surface texture around the mint mark matches the rest of the coin.
On an altered coin, the mint mark has been added after striking. Look for:
- Roughness or disturbance in the field immediately around the D
- A "D" that looks slightly raised or proud of the surrounding field
- Differences in wear, luster and/or color in the area around the mint mark
- Tool marks or scratches near the mint mark under magnification
- A "D" that looks slightly different in style from genuine Denver mint marks of the period
Under a 10x loupe, an added mint mark almost always shows some evidence of the work done to place it there. The metal around the letter will be disturbed, compressed, or show directional marks from the tool used to apply the mint mark. On a genuine coin, the field around the D is smooth and undisturbed.
Third-Party Certification
The most reliable protection against fakes is third-party certification by PCGS, NGC and CACG. All 3 services have examined thousands of 1916-D Mercury Dimes and their experts know every type of fake. A coin in a genuine PCGS, NGC and CACG holder has been authenticated and graded by professionals. If you are spending serious money on a 1916-D, buy certified.
Grading the 1916-D Mercury Dime
Mercury Dimes are graded on the standard Sheldon scale from Poor-1 through Mint State-70. For the 1916-D specifically, here is what to look for at each major grade level:
Good (G-4 to G-6): The design is visible but heavily worn. Liberty's portrait shows as a flat outline. The date and mint mark are readable. The rim is complete but may be worn into the lettering in places. This is the most common grade for 1916-D examples.
Very Good (VG-8 to VG-10): More detail visible in Liberty's hair and cap. The date and mint mark are clear. Some design elements are still flat but the overall coin has more definition than Good.
Fine (F-12 to F-15): Moderate wear with major design elements clear. Liberty's hair shows some detail. The bands on the fasces may show partial separation.
Very Fine (VF-20 to VF-35): Light to moderate wear. Liberty's hair shows good detail. The fasces bands show more definition. The olive branch is clear.
Extremely Fine (EF-40 to EF-45): Light wear on the high points only. Liberty's cheekbone and the top of the cap show slight wear. The fasces bands are clear though Full Bands designation requires complete separation.
About Uncirculated (AU-50 to AU-58): Slight wear on the very highest points. Most of the original luster is present. AU-58 examples can be difficult to distinguish from Mint State without careful examination.
Mint State (MS-60 to MS-67): No wear. Graded on quality of strike, luster, and surface preservation. Full Bands (FB) examples command significant premiums at all Mint State grades.

Full Bands examples at the top of the Mint State scale are among the most valuable Mercury Dimes in existence. An MS-66 FB 1916-D is a coin that appears at major auction houses and attracts serious bidding from advanced collectors.
The Full Bands Premium
The Full Bands designation deserves special attention because it has such a dramatic effect on value. The horizontal bands that bind the fasces on the reverse of a Mercury Dime must show complete, uninterrupted separation across their full width to qualify for the FB designation. On a weakly struck coin, the bands merge together and show no separation. On a fully struck coin, each band is distinct and clearly separated from the ones above and below it.
For the 1916-D, Full Bands examples are genuinely rare because the Denver Mint's strike quality in 1916 was inconsistent. Many 1916-D dimes show weak or partial band separation even in high Mint State grades. A fully struck 1916-D with complete band separation is a coin that collectors actively seek and pay substantial premiums to acquire.
Other Important Mercury Dime Dates
While the 1916-D is the undisputed key date, the Mercury Dime series has several other important dates worth knowing:
1921: Mintage of 1,230,000 from Philadelphia. The second lowest mintage in the series after the 1916-D. The 1921 is worth $40 to $80 in Good condition up to $3,000 to $4,000 in MS65.
1921-D: Mintage of 1,080,000 from Denver. Slightly lower mintage than the 1921-P and similarly valued. Worth $50 to $100 in Good condition up to $3,000 to $4,000 in MS65.
1926-S: Low mintage San Francisco issue. Worth $8 to $350 depending on grade.
1931-S: Another Depression-era low mintage. Worth $6 to $350 depending on grade.
1942/41 Overdate: One of the most famous overdates in American coinage. The 1942 date was punched over a 1941 date, leaving traces of the 1 visible under the 2. Both Philadelphia and Denver versions exist. Worth $200 to $10,000+ depending on grade and variety.
Why Mercury Dimes Are Worth Collecting
The Mercury Dime series ran for thirty years and includes coins from every major period of American history in the first half of the twentieth century. The series spans World War I, the Roaring Twenties, the Great Depression, and World War II. Every coin in the series is 90 percent silver, giving even common dates intrinsic metal value.
For collectors, the Mercury Dime series is one of the most satisfying to complete. The coins are small enough to store easily, beautiful enough to display, and varied enough to provide a genuine challenge. A complete set in circulated grades is achievable for most collectors. A complete set in Mint State with Full Bands is a lifetime project that only the most dedicated and well-funded collectors accomplish.
The 1916-D is the coin that defines the series. Every Mercury Dime collector wants one. Every advanced collector who has one treasures it.
