The 1929 Mercury Dime (no mint mark) is worth anywhere from $3 to $5 in heavily worn condition, up to $50 or more in well-preserved grades, and potentially hundreds of dollars in near-perfect mint state. If you found one of these small silver coins tucked away in a drawer or inherited jar, you might be holding something genuinely valuable.
What Is the 1929 Mercury Dime and Where Was It Made?
The 1929 Mercury Dime with no mint mark was struck at the Philadelphia Mint, which was standard practice — Philadelphia coins didn’t carry a mint mark during this era. Designed by Adolph Weinman, the coin features a young Liberty wearing a winged cap (often mistaken for the Roman god Mercury, which is how the nickname stuck) on the obverse, and a fasces bundle with an olive branch on the reverse.
Philadelphia produced over 19 million of these dimes in 1929, making them relatively available compared to some other dates in the Mercury Dime series. However, most coins that survived everyday circulation are worn, which affects their value considerably.

How Much Is the 1929 Mercury Dime Worth by Grade?
The value of any coin comes down to condition — or “grade” in collector language. A 1929 Mercury Dime that’s been in circulation for decades will show heavy wear on Liberty’s cheek, hair detail, and the fasces on the back. Coins with more visible detail command significantly higher prices.
Here’s a general value breakdown based on coin grade:
| Grade | Description | Estimated Value |
|---|---|---|
| Good (G-4) | Heavy wear, outline visible | $3 – $4 |
| Fine (F-12) | Moderate wear, some detail | $5 – $8 |
| Extremely Fine (EF-40) | Light wear on high points | $15 – $25 |
| About Uncirculated (AU-55) | Slight wear, mostly sharp | $30 – $50 |
| Mint State (MS-63) | No wear, minor contact marks | $60 – $100 |
| Mint State (MS-65+) | Gem quality, sharp luster | $150 – $400+ |

The Silver Content Factor — It’s Worth Something Either Way
One thing many people don’t realize is that Mercury Dimes are 90% silver. Even a worn, low-grade 1929 Philadelphia dime has intrinsic melt value based on its silver content.
Each Mercury Dime contains approximately 0.07234 troy ounces of pure silver. With silver prices fluctuating around $25–$30 per troy ounce in recent years, that puts the base silver value of any Mercury Dime at roughly $1.80 to $2.20 just for the metal.
So even if your coin is too worn to excite a collector, it still has real silver value. Coin dealers and precious metals buyers are always interested in 90% silver coins, sometimes called “junk silver” — though that term is a bit misleading for something with genuine metal worth.
How to Tell If Your 1929 Dime Is Worth More Than Face Value
To get a good read on your coin’s condition, hold it under a bright light and look closely at the hair strands on Liberty’s portrait and the bands on the fasces on the reverse. If you can see individual hair lines and the horizontal bands crossing the vertical fasces sticks are still visible, your coin is in Fine condition or better — and that pushes the value up noticeably.
A key detail that serious collectors look for is the “Full Bands” (FB) designation on the reverse. If both sets of horizontal bands on the fasces are complete and fully separated, the coin can carry a significant premium in higher grades.
CoinHix is a popular tool among hobbyists for looking up exactly these kinds of details — it breaks down Mercury Dime prices by grade, mint mark, and special designations so you’re never guessing.

Should You Clean or Sell Your 1929 Mercury Dime?
If you’re tempted to clean your old coin to make it look shiny — don’t. Cleaning a coin actually damages it in the eyes of collectors. It removes the natural patina and luster that coins develop over decades, and a cleaned coin will always be worth less than an uncleaned one of the same grade.
If you think your coin might be in Extremely Fine or better condition, consider having it professionally graded by PCGS or NGC. The cost is usually $20–$40 per coin, and for a gem-quality Mercury Dime it could unlock significantly more value when you sell.
For everyday folks just getting started, CoinHix makes it easy to research what you have without needing expert knowledge from day one.
Frequently Asked Questions
Q: How do I know if my 1929 dime is a Philadelphia coin (no mint mark)?
A: Look at the reverse side of the coin, just above the “E” in “ONE DIME.” Philadelphia coins have no mint mark there. If you see a small “D” it’s Denver; a small “S” means San Francisco.
Q: Is the 1929 Mercury Dime rare?
A: The 1929 Philadelphia issue is not considered rare — over 19 million were minted. However, coins in uncirculated or gem mint state grades are far less common and can be worth substantial premiums. Common doesn’t always mean cheap.
Q: What’s the best way to find out exactly what my coin is worth today?
A: Start with a visual grade comparison using photos from a coin guide or app. Then check recent sold listings on eBay or use a dedicated tool like CoinHix to see what similar coins have sold for in your coin’s grade. If you suspect it’s high-grade, professional grading is worth the investment.
