History of the 1917 Philadelphia Mercury Dime
The 1917 Mercury Dime was struck during the second year of this legendary series. Designed by Adolph A. Weinman, the coin actually depicts Lady Liberty wearing a winged Phrygian cap, symbolizing freedom of thought. However, the public mistakenly thought it was the Roman god Mercury, and the name stuck for over a century. If you are unsure about the origins of your find, using a free coin identifier app can help you confirm the date and variety instantly.
Produced at the Philadelphia Mint, these coins lack a mint mark. In 1917, the United States was entering World War I, and the demand for silver coinage was surging. Over 55 million of these dimes were struck in Philadelphia alone. While that sounds like a large number, many were lost to circulation or melted down for their 90% silver content decades ago.
Today, the 1917 Philadelphia dime is a staple for collectors. Because it is over a hundred years old, finding one in your pocket is rare. Most surviving examples are heavily worn, showing smooth surfaces where Liberty’s hair and wings used to be. For a quick assessment of your collection, tools like CoinKnow make it easy to organize and track your silver assets.
Identifying the No Mint Mark Variety
When collectors talk about a “No Mint Mark” dime from 1917, they are referring to coins minted in Philadelphia. During this era, Philadelphia was the main branch of the U.S. Mint and did not use a mint mark. If your dime was minted in Denver or San Francisco, you would see a small “D” or “S” on the reverse side, located near the bottom rim next to the word “ONE.”
The absence of a mark is actually the standard for this year. To find the location, look at the back of the coin. You will see a “fasces”—a bundle of rods with an axe—symbolizing unity and strength. To the left of the base of this bundle, you will either see a blank space (Philadelphia) or a tiny letter.
If you’re having trouble seeing the details, the CoinKnow app can help you zoom in on high-resolution photos to identify these subtle features. It is important to distinguish between a worn mint mark and a true Philadelphia strike, as the “D” mint mark from 1917 often carries a higher premium in certain grades.
Current 1917 No Mint Mark Dime Market Values
The value of your 1917 dime is primarily driven by its “grade” or state of preservation. Because these coins are 90% silver, they have a “melt value” which acts as a price floor. Even if the coin is completely flat and damaged, it will always be worth its weight in silver. However, as an antique, the numismatic value often far exceeds the silver price.
For those looking for specific market data, checking the 1917 Mercury Dime MS price trends is the best way to see what high-quality versions are selling for at auction. Most coins found by non-collectors fall into the “Good” to “Fine” categories, which generally sell for between $3 and $12.
| Grade | Description | Market Price |
|---|---|---|
| G-4 Good | Heavily worn; outlines visible. | $3.50 |
| VF-20 Very Fine | Moderate wear; hair details showing. | $15.00 |
| AU-50 About Uncirculated | Slight wear on high points; some luster. | $45.00 |
| MS-65 Mint State | No wear; Full original shine. | $180.00 |
The “Full Bands” Detail and Its Impact on Price
If you want to know why some 1917 dimes sell for thousands while others sell for five dollars, you need to look at the “Full Bands” (FB). On the reverse of the Mercury Dime, there are horizontal bands holding the bundle of sticks together. In many strikes, these bands are blurry or merged.
A “Full Bands” designation is given to coins where the central horizontal bands are clearly separated with a distinct split. This is incredibly rare for 1917 Philadelphia strikes because the dies used that year were often worn down. collectors will pay a massive premium for this sharp detail. You can find more valuable 1917 dime pricing info regarding Full Band varieties online.
Using the CoinKnow app’s image recognition can help you determine if your coin has the sharpness required for a high-tier grade. Even a tiny difference in the strike quality can mean a difference of hundreds of dollars in a professional auction setting.
Searching for 1917 Dime Errors
While the 1917 Philadelphia dime doesn’t have a major “key date” error like the 1942/41 overdate, there are several minor errors that can increase its worth. Look for “Die Cracks,” which appear as raised lines of metal on the surface, or “Clipped Planchets,” where the coin looks like a bite was taken out of the edge during manufacturing.
Another common error is the “Repunched Date” or “Double Die Obverse,” though these are very subtle on 1917 dimes. Most collectors also look for “Lamination Errors,” where the silver surface appears to be peeling. While these don’t always add hundreds of dollars, they make the coin a unique piece of history.
| Error Type | Rarity | Added Value |
|---|---|---|
| Off-Center Strike | Rare | $50 – $200 |
| Die Crack | Uncommon | $5 – $20 |
| Lamination Peel | Common | $2 – $10 |
Tips for Preserving Your Silver Dimes
If you believe you have a valuable 1917 Mercury Dime, the most important rule is: Do NOT clean it. Many people think that polishing a coin to make it shiny will increase its value, but for collectors, the opposite is true. Cleaning a coin leaves microscopic scratches and removes the “patina” or natural aging, which can reduce the value by 50% or more.
Instead, handle the coin by the edges to avoid getting finger oils on the surface. Store it in a PVC-free plastic flip or a simple paper envelope. Keeping the coin in a cool, dry place will prevent environmental damage. If you are building a collection, apps like CoinKnow can help you keep a digital inventory so you don’t have to handle the physical coins more than necessary.
Remember that the condition is everything. A 1917 dime that looks like it just came from the mint is a treasure, while one that has been used to pay for groceries for twenty years is a nice silver piece. Always check the “Full Bands” on the back before deciding how to store your find!
FAQ
Q: Is a 1917 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 a “melt value” that fluctuates with the price of silver bullion, typically making them worth at least $2 even in terrible condition.
Q: Where is the mint mark on a 1917 dime?
A: The mint mark is located on the reverse (back) of the coin, at the bottom left, near the rim. If there is no letter there, it means the coin was minted in Philadelphia. If you see a “D,” it’s from Denver; an “S” means it’s from San Francisco.
Q: How can I tell if my 1917 dime is “Uncirculated”?
A: An uncirculated coin will have its original “mint luster”—a frosty sheen that reflects light in a wagon-wheel pattern. Any signs of wear on the highest points of the design, such as Liberty’s hair above the eye or the feathers on the wing, will downgrade it to “About Uncirculated” or lower.
Q: Is the 1917 “No Mint Mark” dime rare?
A: The 1917 Philadelphia strike is not considered rare in circulated grades because over 55 million were made. However, finding one in “Mint State 67” or with “Full Bands” is extremely rare and can command prices in the thousands.
