| Fine (F-12) | $6.50 – $10.00 |

The History and Appeal of the 1929-D Mercury Dime
If you have just discovered a small silver coin featuring a profile with wings on its head, you are holding a piece of American history known as the Mercury Dime. Officially called the Winged Liberty Head dime, this series ran from 1916 to 1945 and is widely considered one of the most beautiful coins ever minted in the United States. To quickly identify your find, you can use a best coin identifier app to see if you have the 1929 Denver mint version.
The 1929-D Mercury Dime was struck at the Denver Mint just as the United States was entering the Great Depression. With a mintage of roughly 5 million pieces, it is significantly scarcer than the Philadelphia version from the same year. For the everyday person, the most important thing to know is that these coins are made of 90% silver. This means even if the coin is completely worn down, it still holds “melt value” based on the current price of silver bullion.
Using tools like CoinHix can help you determine the exact weight and purity, but generally, any dime from 1929 is worth keeping. The “D” mint mark is located on the reverse (tails) side, near the bottom left, just after the word “ONE.” Finding that little “D” can instantly double the value of the coin compared to a standard Philadelphia issue with no mint mark.
Understanding 1929-D Mercury Dime Value by Grade
When professional collectors look at your 1929-D Mercury Dime, the first thing they assess is the “grade.” Grade refers to the physical condition of the coin—how much of the original detail remains after decades of being spent in stores and carried in pockets. A coin that looks shiny and “new” will always command a premium over one that is smooth and flat.
For the 1929-D specifically, the middle-range grades are where most people find their coins. A “Fine” condition coin shows some hair detail on Liberty and distinct lines in the olive branch on the back. However, if you are lucky enough to have a “Mint State” coin, the current market value for 1929-D uncirculated dimes can reach several hundred dollars.
Below is a detailed breakdown of how grading impacts the price you can expect to receive from a dealer or at auction.
| Grade Designation | Appearance | Price Range |
|---|---|---|
| Good (G) | Heavy wear, outlines visible but flat. | $3 – $5 |
| Very Fine (VF) | Moderate wear; hair details emerging. | $12 – $18 |
| About Uncirculated (AU) | Slight wear on high points; original luster. | $40 – $55 |
| Mint State (MS-65) | Perfectly preserved; no wear. | $150 – $350 |
The “Full Bands” Factor for 1929-D Mercury Dimes
In the world of Mercury Dime collecting, there is a special designation known as “Full Bands” (FB). This refers to the horizontal bands that wrap around the fasces (the bundle of sticks) on the reverse side of the coin. If the central bands are clearly separated with a distinct line between them, the coin is considered a Full Band strike.
For the 1929-D, Full Band examples are quite rare because the Denver Mint often had issues with weak strikes that year. Because of this rarity, a 1929-D with Full Bands can be worth five to ten times more than a standard dime of the same grade. If you think your coin has this detail, using an app like CoinHix can help you zoom in and compare your coin to known FB specimens.
Retailers and collectors often check a comprehensive guide to 1929-D Mercury Dime worth to see current auction records for FB coins. While a standard MS-63 might sell for $70, that same coin with Full Bands could easily fetch $250 or more at a major coin show.
Silver Content: The Base Value of Your Coin
Whenever the economy gets shaky, people start looking for “junk silver.” This is a term used for old U.S. coins like the 1929-D Mercury Dime that are too worn for collectors but are still made of precious metal. Even if your dime is scratched, bent, or smoothed over, it is never worth “just ten cents.”
Every Mercury Dime contains 0.07234 troy ounces of pure silver. To find the minimum value of your coin, you simply multiply that number by the current spot price of silver. This provides a “floor” for the value, ensuring that your 1929-D dime is almost always worth at least 15 to 20 times its original face value.
For those managing a larger collection of found coins, the CoinHix app is fantastic for tracking the total silver weight of your hoard. This ensures that you aren’t taken advantage of if you decide to sell your coins to a local scrap metal buyer or a pawn shop.

|---|---|
| Silver | 90% |

Common Errors and Varieties to Watch For
While the 1929-D is not primarily known for major “king of all errors” varieties, there are several things an eagle-eyed beginner should look for. Sometimes, the mint mark “D” might look doubled, or there may be small die cracks across the surface. These minor errors don’t necessarily turn a $5 coin into a $5,000 coin, but they do add interest and a small premium for specialists.
The most common “issue” found on 1929-D dimes is actually environmental damage. Because these coins were used heavily during the depression, many found today are stained or have “PVC damage” from being stored in cheap plastic holders. It is vital that you never clean your coin. Scrubbing a 1929-D Mercury Dime with silver polish or even soap and water will ruin its numismatic value instantly.
A natural patina or “toning”—where the silver turns shades of blue, rainbow, or deep black—is actually preferred by collectors. If you find a coin that looks “dirty,” leave it as is! Its natural state is exactly what a high-end buyer is looking for.
How to Sell Your 1929-D Mercury Dime
If you’ve determined that your 1929-D Mercury Dime is in great shape or has Full Bands, your next step is finding a buyer. For coins worth less than $20, a local coin shop is usually your best bet. They will buy it for the silver value plus a small premium.
For higher-value coins, consider online marketplaces or reputable auction houses. Before you sell, make sure you have a clear idea of the current market. Checking the latest sales data is essential. You can often find this information via specialized coin valuation tools that aggregate recent eBay and Heritage Auction results.
Finally, if you suspect your coin is in the “Uncirculated” category (MS-60 or higher), it might be worth sending it to a professional grading service like PCGS or NGC. A certified grade “capsulates” the coin, proving its authenticity and quality to potential buyers, which often allows you to sell the coin for a much higher price than an uncertified “raw” coin.
FAQ
Q: Where is the mint mark on a 1929-D Mercury Dime?
A: The mint mark is located on the reverse side of the coin. Look at the bottom left, near the rim, just to the left of the base of the fasces (the bundle of sticks). You will see a small “D” for Denver. If there is no letter, it was minted in Philadelphia.
Q: Is a 1929-D Mercury Dime made of real silver?
A: Yes, all Mercury Dimes minted between 1916 and 1945 are composed of 90% silver and 10% copper. This gives them an intrinsic value that fluctuates with the global price of silver.
Q: Should I clean my old Mercury Dime to make it worth more?
A: Absolutely not. Cleaning a coin with chemicals or abrasives creates micro-scratches on the surface that professional graders can easily detect. A cleaned coin is often worth significantly less than an uncleaned one, even if the uncleaned one looks “dirty.”
Q: How many 1929-D Mercury Dimes were made?
A: The Denver Mint produced 5,034,000 Mercury Dimes in 1929. While this sounds like a large number, many were lost to time or melted down, making high-quality survivors relatively rare today.
