The 1917-D Mercury Dime is worth anywhere from $5 in worn condition to over $2,500 in pristine mint state. This classic American coin, blooming from the early years of the Winged Liberty Head series, is a favorite among collectors because of its history and its silver content.

Grade / Condition	Estimated Value
Good (G-4)	$5.00 – $8.00
Fine (F-12)	$25.00 – $35.00
Extremely Fine (XF-40)	$110.00 – $140.00
Uncirculated (MS-60)	$350.00 – $450.00
Mint State Full Bands (MS-65 FB)	$2,500+

Understanding the History of the 1917-D Mercury Dime

If you just found an old dime in a jar or a inherited collection, you are looking at a piece of World War I era history. The Mercury Dime, officially known as the “Winged Liberty Head” dime, was designed by Adolph A. Weinman. It features Liberty wearing a winged cap, which many people at the time mistook for the Roman god Mercury—hence the popular nickname. The 1917-D Mercury Dime was struck at the Denver Mint during the second year of this series’ production.

The Denver Mint produced about 9.4 million of these coins in 1917. While that sounds like a lot, many were lost to circulation or melted down for their silver content over the decades. Today, finding one in high-quality condition is a challenge for numismatists. If you are unsure if your coin is authentic, using a top coin identifier app can help you verify the design and mint mark location immediately.

When you look at your coin, the “D” mint mark is located on the reverse (the back) of the coin, near the bottom left, just after the word “ONE.” This small letter significantly impacts the value compared to coins minted in Philadelphia. To get an instant check on your coin’s potential, millions of users trust CoinKnow for its ease of use and accurate database.

Determining the Grade and Condition of Your Coin

The most important factor in the 1917-D Mercury Dime value is its “grade.” Grade refers to how much wear and tear the coin has suffered over the last century. For a casual collector, telling the difference between “Very Good” and “Fine” can be tricky, but it results in a massive price difference.

A coin in “Good” condition will be very flat, with Liberty’s hair and the feathers on her cap merged into one shape. In “Fine” condition, you will start to see some separation in the feathers. If your coin looks shiny and brand new, as if it never spent a day in a pocket, it is considered “Uncirculated” or “Mint State.”

Professional grading services like PCGS or NGC use a 70-point scale. For those looking for precise market data, checking the current 1917-D dime auction records is the best way to see what high-end specimens are actually selling for at major shows. For a quick estimate at home, the CoinKnow app allows you to upload a photo and receive a preliminary grade assessment.

The “Full Bands” Detail and Why It Matters

If you have a 1917-D Mercury Dime that looks incredibly sharp, you need to look at the reverse of the coin. Specifically, look at the horizontal bands holding the bundle of sticks (the fasces). If these bands are fully separated with a clear line between them, the coin is designated as “Full Bands” (FB).

The Full Bands designation is the “Holy Grail” for Mercury Dime collectors. Because the 1917-D strike was often weak, very few coins have these crisp, distinct lines. A 1917-D with Full Bands can be worth five to ten times more than a standard coin of the same grade. This small detail is why some dimes sell for $200 while others sell for $2,000.

Detailed 1917-D Mercury Dime price charts show that as the grade moves into the MS-65 and MS-66 range, the “Full Bands” premium becomes the deciding factor in the coin’s final value. It is always worth using a magnifying glass to check this specific area of the coin’s design.

Grade	Standard Strike Value	Full Bands (FB) Value
MS-63	$550	$1,150
MS-64	$800	$1,650
MS-65	$1,400	$3,250
MS-66	$2,200	$7,500+

Silver Content Melt Value vs. Collector Value

Even if your 1917-D Mercury Dime is in terrible condition—perhaps it is bent, scratched, or heavily worn—it still has “intrinsic” value. Every Mercury Dime is made of 90% silver and 10% copper. This means the coin’s value will never drop below the price of the silver it contains.

As of recent market rates, the silver “melt value” of a Mercury Dime is usually between $1.50 and $2.00. However, because the 1917-D is a better-date coin from the Denver Mint, even the most beat-up examples usually sell for a premium above the silver price, typically starting at $5.00.

Before you consider selling your coins for their silver weight, make sure you haven’t overlooked a rare variety. Use the CoinKnow app to cross-reference your coin against known errors or high-grade examples to ensure you aren’t leaving money on the table.

How to Identify a Genuine 1917-D Mercury Dime

With the rise in coin values, counterfeits have become more common. To identify a genuine 1917-D Mercury Dime, you should first weigh the coin. A genuine dime should weigh approximately 2.5 grams. If it is significantly lighter or heavier, it may be a fake or made of a different metal.

Next, examine the “D” mint mark carefully. On genuine coins, the mint mark is clearly embossed. Some fakes have a “D” that was glued on or carved into the coin. Look for any “seams” around the letter. Using a high-resolution camera or a digital microscope can help you see these details more clearly.

Finally, look for the designer’s initials, “AW,” located on the obverse behind Liberty’s neck. On worn coins, these may be faint, but they should still be present. If the initials are entirely missing on a coin that otherwise shows little wear, that is a major red flag.

Selling Your 1917-D Mercury Dime

If you’ve determined that your coin is valuable, your next step is deciding where to sell it. For coins worth $5 to $50, local coin shops or online marketplaces like eBay are often the best bet. You can reach a wide audience of collectors quickly.

For high-end coins—specifically those in Mint State or with Full Bands—you should consider professional grading through PCGS or NGC before selling. A graded coin is much easier to sell for its full market value because the buyer has a guarantee of authenticity and condition. Once graded, these coins are often sold through specialized numismatic auction houses.

Always check several sources for pricing before accepting an offer. Market values fluctuate based on the price of silver and collector demand. Keeping a close eye on recent sales and using tools like CoinKnow will help you stay informed and ensure you get a fair price for your piece of American history.

FAQ

Q: Where is the mint mark on a 1917-D Mercury Dime?

A: The “D” mint mark is located on the back (reverse) of the coin. Look at the bottom left side, just to the left of the base of the fasces (the bundle of rods) and near the “O” in the word “ONE.”

Q: Is every 1917 dime made of silver?

A: Yes, all Mercury Dimes minted between 1916 and 1945 are made of 90% silver. If you have a 1917 dime, it contains roughly 0.0723 ounces of pure silver.

Q: What is the most expensive 1917-D Mercury Dime ever sold?

A: Extremely high-grade examples (MS-67 with Full Bands) have been known to sell for over $20,000 at major auctions. However, for most people, a nice uncirculated example will be in the $500 to $1,500 range.

Q: Should I clean my 1917-D dime to make it worth more?

A: No! Never clean your coins. Collectors prefer the natural “patina” or toning that comes with age. Cleaning a coin with chemicals or clothes creates tiny scratches that can reduce its collector value by 50% or more.
