The 1929 Mercury dime sits at one of the most interesting crossroads in American numismatic history – struck just months before the Wall Street Crash that launched the Great Depression, yet surviving in surprisingly good condition compared to coins from earlier decades. These 90% silver dimes, designed by Adolph A. Weinman, are affordable, historically rich, and carry real silver value at today’s spot price of around $77 per ounce.
Three mint varieties exist for 1929: Philadelphia (no mint mark), Denver (D), and San Francisco (S). Each tells a different story in terms of rarity, strike quality, and collector demand. Whether you’re a seasoned numismatist building a complete Mercury set or a silver stacker looking for history at a low premium, the 1929 issues offer something worth understanding.

Design and Specifications of the 1929 Mercury Dime
Adolph A. Weinman designed the Mercury dime series in 1916, the same year he produced the Walking Liberty half dollar. The obverse shows Lady Liberty wearing a winged Phrygian cap – the “Mercury” nickname stuck because the cap resembles the winged hat of the Roman messenger god, but the coin has nothing to do with Mercury directly. Liberty faces left, and the word LIBERTY arcs above her portrait.
The reverse carries a fasces – a bundle of rods bound around an axe – flanked by an olive branch. The fasces represented unity and civic strength in ancient Rome, long before it was co-opted by 20th-century political movements. The olive branch signals peace. Together, they made a powerful design statement for the era.
Core specifications every collector should know:
| Specification | Detail |
|---|---|
| Composition | 90% silver, 10% copper |
| Weight | 2.50 grams (0.0804 oz total) |
| Silver content | 0.0723 troy oz pure silver |
| Diameter | 17.90 mm |
| Edge | Reeded |
| Designer | Adolph A. Weinman |
| Face value | 10 cents |
At $77/oz silver, the melt value of a single 1929 Mercury dime works out to roughly $5.57. Even a heavily worn example is worth more than 55 times its face value on silver content alone.
The Three 1929 Mercury Dime Varieties
1929 Philadelphia (No Mint Mark)
The Philadelphia mint struck approximately 25,970,000 dimes in 1929 – the highest output of the three facilities that year. No mint mark appears; Philadelphia coins of this era carried no identifying letter. Despite the large mintage, survival estimates across all grades sit around 10,000 coins, and gem examples are genuinely scarce. PCGS rates MS65+ Philadelphia examples at a rarity level of R-6.0, meaning fewer than 20 known specimens exist at that grade. A 1929 Philadelphia dime graded MS67+ sold at auction for $2,468 in 2019.
For circulated examples, values start around $3 in Good (G-4) condition and climb to $12 or more in Extremely Fine (XF-45). Uncirculated examples start around $20 and rise sharply with grade.
1929-D (Denver)
Denver’s 1929 output was lower than Philadelphia’s, and the coins show a “D” mint mark at the bottom of the reverse. Denver dimes from this period are occasionally found with striking errors, including broadstrikes – coins struck outside the collar die, causing the planchet to expand beyond its normal diameter. A mint-state broadstrike example is a legitimate rarity and commands a significant premium over standard examples.
Circulated 1929-D values run slightly higher than Philadelphia in mid-grades: around $5 in VG-8 and $15 in Fine (F-12). Error coins with documented broadstrikes or off-center strikes are worth researching individually through PCGS or NGC population reports.
1929-S (San Francisco)
With only 4,730,000 coins struck, the 1929-S carries the lowest mintage of the three varieties. San Francisco dimes from this year are considered semi-key dates in the Mercury series. Well-struck examples show strong luster and sharp fasces detail, making the 1929-S a candidate for Full Bands designation – a premium that matters a great deal to serious collectors.
High-grade 1929-S coins in MS67+ with Full Bands can bring hundreds to over a thousand dollars at auction. Even MS65 examples often sell for under $200, making them a compelling entry point for collectors who want a low-mintage coin in a high grade without spending four figures.
For broader context on how the 1929-S fits into the full Mercury dime run, the complete Mercury dime collection guide covers every year from 1916 to 1945.
What Full Bands Means and Why It Matters
Full Bands (FB) is a designation applied to Mercury dimes where the horizontal bands on the fasces show complete, separated lines rather than merging from weak strikes or wear. It is a strike-quality indicator, not a grade, but it significantly affects value.
The 1929-S rewards careful searching. Many examples were well-struck at San Francisco, but not all. When buying raw (unslabbed) coins, inspect the bands before paying a Full Bands premium. When buying slabbed coins, PCGS and NGC labels will explicitly state “FB” if the coin qualifies.
Grading the 1929 Mercury Dime
The Sheldon scale runs from 1 to 70. For Mercury dimes, the most practical grades to understand are:
| Grade | Label | What to Look For |
|---|---|---|
| G-4 | Good | Major details visible |
| VG-8 | Very Good | Liberty’s cap bands visible but flat |
| F-12 | Fine | Most details intact |
| XF-45 | Extremely Fine | Sharp design |
| MS60-MS64 | Uncirculated | No wear |
| MS65+ | Gem Uncirculated | Strong luster |
NGC data from April 2026 places circulated 1929-D values between $2.50 and $28 depending on grade, with uncirculated examples commanding more. The Philadelphia variety in MS67+ has fetched over $2,000 at auction. For current population data, PCGS CoinFacts and the NGC coin explorer are the most reliable resources.
For comparison, see how 1941 Mercury dime values track against the 1929 issues – the later date had higher mintages but its own grade-rarity quirks.
Pricing the 1929 Mercury Dime at $77/oz Silver
Silver at $77/oz changes the math significantly compared to historical price guides. The Red Book (A Guide Book of United States Coins) provides a useful benchmark, but spot-price increases push base values up across the board.
| Variety | G-4 | VG-8 | F-12 | XF-45 | MS60+ |
|---|---|---|---|---|---|
| 1929 Philadelphia | ~$3 | ~$3.50 | ~$6 | ~$12 | $20+ |
| 1929-D | ~$3 | ~$5 | ~$15 | ~$24 | $30+ |
| 1929-S | ~$3 | ~$3.75 | ~$10 | ~$20 | $25+ |
These are floor estimates. Auction results, population scarcity, and Full Bands status push premiums well above these figures. The 1929-S in MS67+ FB can reach into the hundreds or low thousands. The 1929 Philadelphia in MS67+ has cleared $2,000 at major auction houses.
Even at the low end, no 1929 Mercury dime should trade at face value. A worn G-4 example is worth at least $3, and that figure climbs as silver prices rise. Stacking circulated examples for silver content is a legitimate strategy at current spot levels.
Historical Context: Struck on the Eve of the Great Depression
The 1929 Mercury dimes were produced during an economic boom that abruptly ended in October 1929 with the stock market crash. Coins struck that year entered circulation just as the country’s financial market shifted dramatically. Interestingly, this timing may have helped preservation: as economic conditions worsened, people hoarded coins rather than spending them freely, and some 1929 dimes survived in better shape than issues from more prosperous years.
The Mercury dime series ran from 1916 to 1945, when wartime silver demands and the desire for a new design led to the Roosevelt dime. Weinman’s Liberty never appeared on circulating U.S. coinage again. The 1929 issues represent one of the last pre-Depression strikes in the series, giving them a historical weight that purely silver-content calculations don’t capture.

Common Misconceptions About the 1929 Mercury Dime
Several other misconceptions circulate among newer collectors:
- All three varieties are equally rare. They are not. Philadelphia struck over 25 million; San Francisco struck fewer than 5 million. The 1929-S is the coin to prioritize for rarity.
- Low-grade examples have no collector value. A G-4 coin at $3 is still worth more than 30 times face value. Silver content alone justifies buying circulated examples.
- The fasces symbol is political. The fasces predates 20th-century political movements by centuries. On this coin, it represents civic unity and strength – the same meaning it carried in ancient Rome.
- Mercury dimes have a copper core like modern dimes. They do not. The alloy is solid 90% silver and 10% copper throughout, unlike post-1965 clad coinage.
- Weinman designed only this coin. He also designed the Walking Liberty half dollar, struck concurrently – one of the most respected American coin designs ever produced.
Practical Tips for Buying and Authenticating 1929 Mercury Dimes
Look at the bottom of the reverse. “D” = Denver, “S” = San Francisco, no letter = Philadelphia.
A genuine example weighs 2.50 grams. Significant deviation suggests a problem.
Use a 10x loupe. Full, separated bands on the fasces = Full Bands quality. Merged lines = no FB designation.
Cleaned coins show hairlines under a loupe and dull, unnatural luster. Avoid them unless pricing reflects the damage.
Broadstrikes on 1929-D examples show expanded diameter and weak rims. These are genuine rarities, not defects to avoid.
For MS65 and above, buy PCGS or NGC graded examples. The population data and grade assurance justify the premium.
For raw coins in lower grades, buying from reputable dealers or established auction platforms reduces risk. Avoid cleaned coins – they lose significant value and are harder to resell. The numismatic coins category at Accurate Precious Metals includes graded and raw options across multiple series.
Selling Your 1929 Mercury Dime
If you have a 1929 Mercury dime – or a collection of Mercury dimes – and want to sell, the process is straightforward but the details matter. A slabbed MS65+ coin deserves a different approach than a roll of circulated examples.
For individual high-grade coins, having them graded by PCGS or NGC before selling can increase realized value by two to five times compared to selling raw. As an NGC Authorized Dealer, Accurate Precious Metals can assist with the grading submission process.
For circulated examples, silver content is the baseline. At $77/oz, a standard circulated 1929 Mercury dime carries about $5.57 in melt value. Dealers buying in bulk will offer near-melt for common circulated examples. Key-date 1929-S coins, even in worn grades, carry a numismatic premium above melt.

Frequently Asked Questions
How do I know if my 1929 Mercury dime is the Philadelphia, Denver, or San Francisco variety?
Check the reverse of the coin near the bottom. A "D" indicates Denver, an "S" indicates San Francisco, and no mint mark means Philadelphia. The mint mark is small – use a magnifier if needed.
What is the silver melt value of a 1929 Mercury dime today?
At the current silver spot price of approximately $77 per ounce, a 1929 Mercury dime contains 0.0723 troy ounces of pure silver, giving it a melt value of roughly $5.57. This applies to all three mint varieties equally.
Is the 1929-S Mercury dime a key date?
It is considered a semi-key date. With only 4,730,000 struck, it has the lowest mintage of the three 1929 varieties and commands a premium in all grades, especially in uncirculated condition with Full Bands designation.
What does Full Bands mean on a Mercury dime?
Full Bands refers to the horizontal bands on the fasces on the reverse showing complete, separated lines rather than merging together. It indicates a well-struck coin and adds a significant premium, particularly in higher grades.
Are cleaned Mercury dimes worth buying?
Generally, no – not at full market value. Cleaned coins show hairlines and artificial luster under magnification, and both PCGS and NGC will note cleaning on their labels. Cleaned coins sell at a discount and are harder to resell at a profit.
Can I sell my 1929 Mercury dimes to Accurate Precious Metals?
Yes. Accurate Precious Metals buys Mercury dimes in any condition. Visit the Salem, Oregon location in person, or use the mail-in service if you are located elsewhere in the United States. Both options include professional evaluation and competitive offers based on current silver spot prices and numismatic value.
How does the 1929 Mercury dime compare to other years in the series?
The 1929 issues are mid-series coins with moderate to low mintages. They are more affordable than key dates like the 1916-D or 1921, but the 1929-S offers genuine rarity in high grades. For comparison, the 1935 Mercury dime had higher mintages and is generally less scarce in gem grades.
