The 1979 Roosevelt Dime with no mint mark is worth anywhere from its $0.10 face value in worn condition to over $100 in high-grade mint state. While most of these coins found in your change today are common, certain rare varieties and high-quality specimens can fetch a surprising premium from coin collectors.
| Condition | Estimated Value |
|---|---|
| Circulated (Average) | $0.10 – $0.25 |
| Uncirculated (MS60-MS63) | $1.00 – $5.00 |
| Choice Mint State (MS65+) | $15.00 – $100+ |
| Full Torch (FT/FB) Rare Grade | $250 – $1,500 |
Identifying the 1979 Roosevelt Dime No Mint Mark
If you have just emptied your piggy bank and found a 1979 dime without a small letter near the date, you might wonder if you’ve struck gold. To accurately identify your find, you can use the best coin identifier app to scan the coin’s features instantly. These dimes were struck at the Philadelphia Mint. Unlike today, where Philadelphia coins often bear a “P” mint mark, in 1979, the absence of a mark was the standard for this facility.
The coin features the profile of President Franklin D. Roosevelt on the obverse, designed by John R. Sinnock. On the reverse, you will see an olive branch, a torch, and an oak branch, symbolizing peace, liberty, and victory. Because over half a billion of these were produced in Philadelphia alone, they are very common in pocket change.
However, “common” doesn’t mean “worthless.” Collectors look for specific attributes like “Full Torch” lines or exceptional luster. If your coin looks like it just came off the press—shiny, scratch-free, and sharp—it could be worth much more than its face value. For a quick check on the go, the CoinHix app provides real-time market data to help you decide if a coin is worth sending for professional grading.
Understanding the Value of No Mint Mark 1979 Dimes
The primary factor determining the value of your 1979 dime is its condition or “grade.” Most coins you find in circulation have been handled by thousands of people, leading to scratches, smoothed-out details, and a dull grey finish. These circulated coins generally hold no added collector value beyond 10 cents.
For those interested in investment-grade pieces, the 1979 Roosevelt Dime auction records and price trends show that values jump significantly once a coin reaches a “Mint State” (MS) 65 or higher. At MS67, a 1979 dime can sell for $40 to $60. If the coin is graded MS68, the price can skyrocket into the hundreds.
| Grade (Sheldon Scale) | Market Value Range |
|---|---|
| MS63 (Typical Uncirculated) | $1 – $3 |
| MS65 (Choice Uncirculated) | $12 – $18 |
| MS66 (Gem Uncirculated) | $25 – $35 |
| MS67 (Superb Gem) | $55 – $85 |
The “Full Torch” (FT) Premium for 1979 Dimes
In the world of Roosevelt Dime collecting, the “Full Torch” (often abbreviated as “FT” by collectors or “FB” for Full Bands by certain grading services) is the holy grail. This designation refers to the horizontal bands at the top and bottom of the torch on the reverse side. On most 1979 dimes, the striking pressure wasn’t strong enough to make these lines perfectly distinct.
If you find a 1979 dime where these lines are clearly separated with no merging, your coin is significantly more valuable. A 1979 No Mint Mark dime graded MS67 with Full Torch details can easily sell for over $500, as these are incredibly rare. Using CoinHix, you can compare your coin’s reverse to high-resolution photos of FT coins to see if yours makes the cut.
Collectors pay a high premium for these because they represent a “perfect strike.” While millions of dimes were made, only a fraction were struck with enough force and fresh enough dies to produce that level of detail. Always check the reverse of your 1979 dimes before spending them!
Common Errors and Variations to Look For
While the 1979 dime lacks a mint mark naturally, other “errors” can make a coin valuable. Error hunters often look for “broadstrikes,” where the coin was struck without its retaining collar, making it look flat and spread out. Off-center strikes are also popular, where only a portion of the design is visible on the planchet.
Another area of interest is the 1979 dime error list and Proof variety values, which details the differences between regular strikes and Proof coins. In 1979, the San Francisco Mint produced Proof coins with two types of “S” mint marks: Type 1 (Filled S) and Type 2 (Clear S). While these have mint marks, they are often discussed alongside the 1979 Philadelphia issue because they come from the same year’s sets.
| Error Type | Approximate Value |
|---|---|
| 10% Off-Center Strike | $15 – $30 |
| 50% Off-Center Strike | $75 – $150 |
| Double Die Obverse (Minor) | $10 – $25 |
| Broadstruck | $20 – $50 |
Why the 1979 Dime is Not Silver
A common misconception among casual hunters is that older-looking dimes are silver. However, the United States stopped using 90% silver for dimes and quarters in 1964. The 1979 Roosevelt Dime is a “clad” coin, consisting of an inner core of pure copper and an outer layer of 75% copper and 25% nickel.
You can easily verify this by looking at the edge of the coin. If you see a distinct copper-colored stripe, it is a standard clad coin. If the edge is solid silver/white, you might have a rare error or a silver proof, but for 1979, almost every dime found in your pocket will be the copper-nickel variety.
Despite the lack of silver, these coins remain a favorite for “roll hunters”—people who buy boxes of coins from banks to search for high-grade specimens. Finding a pristine 1979 dime in a bank roll is becoming harder every year, which helps maintain the value of uncirculated examples. If you’re unsure about the metal composition, CoinHix features a guide on how to identify silver vs. clad coins by weight and appearance.
How to Store and Protect Your 1979 Dimes
If you believe you have found a high-grade 1979 Roosevelt Dime, proper storage is essential. Touching the surface of a mint-state coin with your fingers can leave oils that eventually cause “toning” or corrosion, lowering the grade and the value. Handle coins only by their edges, ideally using cotton gloves.
For storage, avoid PVC-containing plastic flips, as they can damage the coin’s surface over time. Use archival-quality cardboard 2×2 holders or hard plastic capsules. If you think your coin is a “Full Torch” candidate or a high-grade MS67+, you may want to consider professional grading by services like PCGS or NGC. A certified grade can turn a $10 coin into a $100 coin by providing a guarantee of its condition and authenticity.
In conclusion, while the average 1979 No Mint Mark dime isn’t going to fund a retirement, it provides an excellent entry point into the world of numismatics. By paying attention to the small details—the luster, the clarity of the torch, and the presence of any errors—you might just find a hidden gem in your spare change.
1979 Roosevelt Dime FAQ
Q: Does a 1979 dime with no mint mark mean it’s an error?
A: No. In 1979, the Philadelphia Mint did not use a mint mark on dimes. It is a completely normal feature for coins produced at that facility during that year.
Q: What is the most expensive 1979 dime ever sold?
A: High-grade specimens with the “Full Torch” designation have sold for over $1,200 at major auctions. These are usually in MS68 condition, which is extremely rare for coins intended for circulation.
Q: How can I tell if my 1979 dime is “Uncirculated”?
A: An uncirculated coin will have its original “mint luster”—a cartwheel effect of light reflecting off the surface—and will show no signs of wear on the high points of Roosevelt’s cheek or the torch’s flame.
Q: Are there any silver 1979 dimes?
A: No, there were no silver dimes produced by the US Mint in 1979. All business strikes and proof coins from this year were made from the copper-nickel clad composition.
