The 1928 Mercury dime is one of the most recognizable silver coins from the Roaring Twenties – a small disc of history that collectors still chase nearly a century later. Struck in 90% silver, designed by sculptor Adolph A. Weinman, and produced at three different U.S. Mints, this dime punches well above its face value whether you’re a silver stacker, a numismatist, or someone who just found one in an old coin jar.
With silver spot currently sitting around $77 per ounce, even a worn 1928 Mercury dime carries real metal value. But the story gets more interesting in higher grades, where branch-mint examples have sold at auction for thousands of dollars. This guide covers everything you need to know – history, varieties, grading, current pricing, and how to buy or sell one wisely.
A Brief History of the 1928 Mercury Dime
The Mercury dime series ran from 1916 to 1945, replacing the older Barber dime as part of a broader push to modernize American coinage. Weinman’s design won out in a competition, and the result was one of the most praised coin designs in U.S. history. The obverse shows a young Liberty wearing a winged Phrygian cap – not the Roman god Mercury, despite the nickname that stuck. Weinman intended the wings to represent freedom of thought.
The reverse features a fasces (a bundle of rods bound around an axe, symbolizing authority and unity) alongside an olive branch representing peace. That combination of strength and peace was intentional, and it made the reverse just as collectible as the obverse.
By 1928, the series was over a decade old and the coins had become everyday pocket change. The Roaring Twenties were in full swing – jazz clubs, Model T Fords, payphones, and gum machines all saw these dimes pass through them regularly. In fact, early design prototypes had to be adjusted because the original rim was too thick for vending machines and payphones of the era. The rim was thinned before mass production, which is why no collectible “thick rim” 1928 variety exists.
The series ended in 1945, replaced by the Roosevelt dime honoring President Franklin D. Roosevelt after his death. For a deeper look at how the series began, the 1917 Mercury dime offers useful context on early design decisions.
Three Mint Varieties of the 1928 Mercury Dime
Three U.S. Mints struck dimes in 1928, and each produced a distinct coin worth understanding separately. The mintmark appears on the reverse, below the fasces.
19,480,000 struck – the most common variety, ideal for new collectors
4,161,000 struck – lower mintage, significantly scarcer in high grades
7,400,000 struck – mid-range availability, but watch for the Full Bands detail
Philadelphia (no mintmark): The highest-mintage variety and the easiest entry point. Circulated examples are affordable, and even uncirculated pieces don’t break the bank at lower grades.
Denver (1928-D): With just over four million struck, this is the toughest of the three to find in top condition. The low mintage combined with heavy circulation during the Depression years means gem examples are genuinely scarce. A 1928-D in MS67 has sold for over $2,400 at major auctions.
San Francisco (1928-S): Falls between the other two in mintage. The key feature to look for here is Full Bands (FB) – a designation given when the horizontal bands on the fasces are fully separated and sharply defined. Full Bands examples command a significant premium, sometimes two to five times the value of a non-FB coin at the same grade. A 1928-S in MS67+ with Full Bands sold for $3,290 at auction in 2023.
Specifications: What’s Inside a 1928 Mercury Dime
Every 1928 Mercury dime shares the same physical composition regardless of mint.
| Specification | Detail |
|---|---|
| Composition | 90% silver, 10% copper |
| Weight | 2.50 grams |
| Diameter | 17.9 mm |
| Edge | Reeded |
| Silver content | 0.07234 troy oz pure silver |
| Designer | Adolph A. Weinman |
| Series | Winged Liberty Head (Mercury) Dimes, 1916-1945 |
At today’s silver spot of $77 per ounce, the raw melt value of a 1928 Mercury dime works out to roughly $5.57 (0.07234 x $77). That’s the floor for any circulated example – no 1928 dime in any condition should sell for less than its silver content.

1928 Mercury Dime Values by Grade and Variety
Condition drives price more than almost any other factor. A heavily worn 1928 Philadelphia dime might sell for $3 to $4, while a gem uncirculated 1928-D can fetch thousands. Here’s a current snapshot of market values across grades.
| Variety | Good (G4) | Fine (F12) | XF (XF45) | MS63 | MS65+ | Auction Peak |
|---|---|---|---|---|---|---|
| 1928 (Philadelphia) | $3 | $3.50 | $7 | $18 | $200-$850 | – |
| 1928-D (Denver) | $4 | $8 | $50 | $95-$198 | $935-$2,420 | MS67 ~$2,500+ |
| 1928-S (San Francisco) | $3 | $4 | $16 | $45 | $500+ (FB higher) | MS67+ $3,290 |
A few things stand out in these numbers. The 1928-D jumps sharply in Extremely Fine and above – that’s where its lower mintage starts to matter. The 1928-S shows a similar curve, especially once Full Bands enters the equation.
For circulated coins in Good to Very Fine condition, expect to pay or receive somewhere between melt value and a modest numismatic premium. In MS60 to MS64 uncirculated range, premiums over melt grow substantially. At MS65 and above, you’re in gem territory where population reports from PCGS and NGC drive pricing as much as anything else.
To track real-time population data and auction prices, PCGS CoinFacts (pcgs.com/coinfacts) and NGC Coin Explorer (ngccoin.com) are the most reliable tools available.
Grading the 1928 Mercury Dime
The Sheldon scale runs from 1 to 70. For Mercury dimes, a few grades matter most in practice.
Good (G4-G6): Heavy wear throughout. The date and mintmark are visible, but Liberty’s features and the fasces detail are mostly flat. Worth melt to a small premium.
Fine (F12-F15): Moderate wear. Hair strands show some separation. The fasces bands are visible but not sharp. A step up from melt in value.
Extremely Fine (XF40-XF45): Light wear on the highest points only. Most design details remain sharp. This is where the 1928-D starts to command real premiums.
Mint State (MS60-MS70): No circulation wear. The difference between MS60 and MS65 comes down to luster quality, contact marks, and eye appeal. MS65 is the gem threshold. Above MS65, population drops sharply and prices rise fast.
For the Full Bands designation on 1928-S coins, the grader examines whether the two sets of horizontal bands crossing the fasces are fully separated – not merged or partially worn. This detail is only visible under magnification and is the single most important factor for 1928-S valuation.
Submitting coins to PCGS or NGC for professional slabbing adds credibility and typically boosts resale value by 20% to 50% over raw coins of similar quality. As an NGC Authorized Dealer, Accurate Precious Metals can assist with the grading submission process – a useful service for anyone sitting on a high-grade example.

Errors and Varieties Worth Knowing
The 1928 issue doesn’t have a famous error coin the way some years do, but that doesn’t mean errors are absent. Doubled dies and off-center strikes do occasionally surface, and when they do in high grades, they attract serious bidder interest at auction.
The more practical variety to understand is Full Bands on the 1928-S. It’s not a minting error – it’s a strike quality designation – but it functions like a variety in terms of how dramatically it affects value. A 1928-S MS65 without Full Bands might sell for a few hundred dollars. The same coin with Full Bands in the same grade can be worth multiples of that.
No collectible “thick rim” 1928 variants exist. Early Mercury dime prototypes were adjusted before mass production to fit vending machines and payphones of the era, and by 1928 the design was fully standardized.
How to Buy a 1928 Mercury Dime
Start by deciding what you want from the coin. Silver stackers looking for bullion value can pick up circulated Philadelphia examples for a few dollars over melt. Type set collectors building a run of Mercury dimes can do the same. Anyone chasing a gem example of the 1928-D or 1928-S is looking at a more serious purchase that warrants professional grading verification.
Decide between circulated (melt + small premium), mid-grade (numismatic value), or gem (investment-level purchase)
Check the reverse below the fasces. No mark = Philadelphia. D = Denver. S = San Francisco.
A genuine 1928 Mercury dime weighs 2.50 grams and measures 17.9 mm. Deviations suggest a problem.
Silver is non-magnetic. A magnet test is a quick first screen. XRF analysis provides precise metal content verification.
For 1928-S coins, use magnification to assess Full Bands status before paying any FB premium.
For any coin above MS64, a PCGS or NGC slab removes guesswork and protects resale value.
Estate sales, coin shows, and reputable dealers are the best sourcing options. Avoid PVC flips for storage – they damage silver surfaces over time. Coin albums or inert plastic holders are safer for long-term storage.
The silver coins category at Accurate Precious Metals is a good starting point for browsing available inventory, including Mercury dimes and other classic U.S. silver issues.
How to Sell a 1928 Mercury Dime
Selling depends heavily on condition. Circulated coins in Good to Fine grades are best sold to a dealer near their silver melt value – don’t expect a large numismatic premium for worn examples. Mid-grade coins in XF or lower uncirculated grades can fetch a modest premium above melt from a knowledgeable buyer.
High-grade examples – particularly 1928-D or 1928-S coins in MS65 and above – deserve a more careful approach. Major auction houses like Heritage Auctions or Legend Numismatics have proven records of realizing strong prices for gem Mercury dimes. The 1928-S MS67+ FB result of $3,290 came through that kind of venue.

Common Misconceptions About the 1928 Mercury Dime
It’s not actually Mercury. The coin depicts Liberty, not the Roman messenger god. The winged cap resembled Mercury’s headgear closely enough that the nickname stuck, but Weinman designed it as a symbol of freedom of thought.
Not all 1928s are cheap. The Philadelphia circulated coin is genuinely affordable. But a 1928-D in gem condition is conditionally rare – the mintage numbers don’t tell the full story because so many circulated heavily. Finding one with original luster and sharp details is harder than the raw mintage suggests.
Melt value isn’t the ceiling for most examples. A 1928-D in XF45 trades at $50 – nearly ten times its silver melt value. Numismatic demand sets the price for anything above heavily worn condition.
Full Bands matters. On the 1928-S, ignoring the fasces band detail when buying or selling is a costly mistake. Always check.
The 1928 Standing Liberty Quarter from the same year offers an interesting parallel – another 90% silver coin from the same era where condition and variety dramatically affect value.
Building a Mercury Dime Collection Around the 1928
The Mercury dime series spans 1916 to 1945, covering 77 date-and-mint combinations. The 1928 issues sit in the “common” middle of the series – not key dates, but not throwaway coins either. For a collector building a type set or a short set of 1920s Mercury dimes, the 1928 Philadelphia is an easy, affordable anchor.
Branch-mint 1920s Mercuries add challenge and reward. Pairing a 1928-D and 1928-S with their Philadelphia counterpart makes a satisfying three-coin set from a single year. Add silver value from $77/oz spot prices and the set has both numismatic and bullion appeal.
For context on a related coin from the same year, the 1928 Standing Liberty Quarter value covers another classic 90% silver issue that pairs naturally with Mercury dime collecting from the same era.

Frequently Asked Questions
How much is a 1928 Mercury dime worth today?
It depends on condition and mint. A worn Philadelphia example might sell for $3 to $4. A 1928-D in Extremely Fine condition can bring $50 or more. Gem uncirculated examples – especially 1928-D and 1928-S – have sold for hundreds to thousands of dollars at auction.
What is the silver content of a 1928 Mercury dime?
Each coin contains 0.07234 troy ounces of pure silver. At the current spot price of $77 per ounce, that works out to a melt value of roughly $5.57.
What does Full Bands mean on a 1928-S Mercury dime?
Full Bands refers to the horizontal bands on the fasces (the bundle of rods on the reverse) being fully separated and sharply defined. This strike quality designation significantly increases value – sometimes two to five times over a non-Full Bands coin of the same grade.
How do I tell which mint struck my 1928 Mercury dime?
Check the reverse of the coin, below the fasces. No mintmark means Philadelphia. A “D” means Denver. An “S” means San Francisco.
Is a 1928 Mercury dime rare?
The Philadelphia issue is common by Mercury dime standards. The 1928-D is scarcer, particularly in high grades. The 1928-S in gem condition with Full Bands is genuinely hard to find. None of the three are key dates, but branch-mint gems command serious premiums.
Where can I sell a 1928 Mercury dime?
Accurate Precious Metals buys silver coins including Mercury dimes. Visit the Salem, Oregon location in person, or use the mail-in service from anywhere in the U.S. High-grade gems may also do well at major coin auctions.
Should I clean my 1928 Mercury dime before selling?
No. Cleaning a coin removes original luster and surface patina, which reduces its numismatic value significantly. Even a coin that looks dirty should be left as-is and assessed by a professional.
What’s the difference between a bullion dime and a numismatic dime?
A bullion coin is valued primarily for its metal content. A numismatic coin carries collector value above melt based on rarity, condition, and demand. Most 1928 Mercury dimes in circulated condition trade close to bullion value, while high-grade examples are clearly numismatic.
