1970 Roosevelt Dime Value: Is Your No Mint Mark Coin Rare?
The 1970 Roosevelt Dime is worth anywhere from its face value of $0.10 in worn condition to over $500 in high-grade mint state. While most are common pocket change, specific errors and high-quality specimens can fetch surprising prices at auction for lucky collectors and everyday finders.
| Condition | Estimated Value (USD) |
|---|---|
| Circulated (Average Wear) | $0.10 – $0.25 |
| Uncirculated (MS60 – MS63) | $1.00 – $5.00 |
| Choice Uncirculated (MS65+) | $15.00 – $80.00 |
| High Grade (MS67+) | $150.00+ |
Identifying the 1970 Roosevelt Dime No Mint Mark
If you’ve just emptied your piggy bank and found a 1970 dime without a small letter near the date, you might be wondering if you’ve struck gold. To accurately identify your find, you can use a free coin identifier app to ensure you aren’t overlooking subtle minting details. In the world of U.S. coinage, a “No Mint Mark” on a 1970 dime simply means it was struck at the Philadelphia Mint. At the time, Philadelphia did not use a “P” mint mark on dimes; this practice only changed in 1980.
Most 1970 dimes you find in your spare change will be Philadelphia issues. Because over 345 million of these were produced, they are incredibly common. However, the value starts to climb when the coin is in “Uncirculated” condition—meaning it looks exactly as it did the day it left the mint, with no scratches or dullness from being handled. Programs like CoinKnow can help you compare your coin’s luster against high-resolution images of museum-quality pieces to see where your coin lands on the scale.
It is also important to note the composition. By 1970, the U.S. Mint had long since transitioned away from silver. These coins are made of a “clad” composition: a core of pure copper sandwiched between layers of cupro-nickel. They do not contain any precious metal, so their value is derived entirely from their numismatic (collector) appeal and condition.
Determining the 1970 Dime Value by Grade
When evaluating a coin, “grading” is the most important factor. Collectors use a 70-point scale. A coin graded 1 is barely recognizable, while a 70 is perfect. For the 1970 Roosevelt Dime, most coins in circulation are considered “Good” to “Extremely Fine.” In these conditions, the coin is generally only worth its face value or a few cents more to a casual collector. People often check the 1970 dime price guide by grade to see how much a pristine specimen can actually earn.
The real money lies in MS67 (Mint State 67) or higher. Because these coins were made for general use, they were tossed into bins and bags, causing tiny nicks and scratches. Finding one without these imperfections is rare. If your coin has a sharp strike and looks “blindingly” shiny, it might be worth sending to a professional grading service like PCGS or NGC.
| Grade | Value Range |
|---|---|
| MS63 | $2 – $4 |
| MS65 | $12 – $20 |
| MS67 | $100 – $180 |
| MS68 | $450+ |
The “Full Band” Mystery and Why It Matters
If you look at the back (reverse) of the Roosevelt Dime, you’ll see a torch. On the torch, there are horizontal bands at the top and bottom. Serious collectors look for “Full Bands” (FB) or “Full Torch” (FT). This means the lines separating the bands are completely clear and uninterrupted. Because the 1970 strikes were often “mushy” or weak, coins with Full Bands are much rarer and more expensive.
A 1970 dime with Full Bands can be worth five to ten times more than a standard dime of the same grade. This is a detail that often goes unnoticed by the general public. Using the CoinKnow app’s macro photography features, you can zoom in on the torch to see if your coin meets this prestigious criteria. It is one of the quickest ways to separate a $0.10 coin from a $50 coin.
The value of these high-tier coins fluctuates based on market demand. For current market trends, you can review the latest market analysis for 1970 Roosevelt dimes to see what auction houses are currently paying for Full Band specimens. Always ensure your coin is protected in a sleeve to maintain that detail.
The Rare 1970-S Proof No Mint Mark Dime
While we are focusing on the Philadelphia “No Mint Mark” dimes found in circulation, we must mention the “holy grail” of 1970 dimes. In 1970, the San Francisco Mint produced Proof sets (special shiny coins for collectors). These were supposed to have an “S” mint mark. However, a small number of Proof Roosevelt Dimes were struck without the “S” mark.
These are not the dimes you find in your pocket change. These are “Proof” coins, which have a mirror-like finish and were sold in plastic cases. If you find a mirror-finish 1970 dime in a collector set that is missing the “S,” you could be looking at a coin worth $500 to over $1,000 depending on the depth of the cameo.
| Type | Rarity | Estimated Auction Price |
|---|---|---|
| 1970 Phil. (Regular) | Extremely Common | $0.10 – $5.00 |
| 1970-S Proof (Regular) | Common (in sets) | $2.00 – $10.00 |
| 1970 “No S” Proof | Extremely Rare | $500 – $1,500 |
Common Errors Found on 1970 Dimes
Aside from the major “No S” proof error, everyday 1970 dimes can feature manufacturing mistakes that add value. One common error is the “Off-Center Strike,” where the coin isn’t lined up perfectly with the dies. This results in a lopsided image. If more than 50% of the design is missing but the date is still visible, the value can jump to $20 or $50.
Another error to look for is “Die Cracks.” As the metal dies used to stamp the coins get old, they crack. This leaves a small, raised line of metal on the surface of the finished dime. While small cracks don’t add much value, large or uniquely placed cracks (like the “Spiking Roosevelt” errors seen in other years) are popular with niche collectors. CoinKnow allows you to browse community forums where other enthusiasts post photos of their recent error finds.
Double dies are less common for this specific year, but they are always worth checking for. If you see doubling in the lettering of “LIBERTY” or “IN GOD WE TRUST,” you might have a valuable discovery. Most “doubling” found by beginners is actually “machine doubling,” which doesn’t add value, but a true Doubled Die is a rare prize.
Summary: Tips for Coin Hunters
If you’re hunting through rolls of dimes from the bank, the 1970 Roosevelt Dime No Mint Mark is usually a pass unless it is in pristine, sparkling condition. Always keep an eye out for the elusive Proof sets in estate sales or pawn shops, as the “No S” error remains a top-tier target for professional hunters.
Remember to handle your coins by the edges. The oil from your skin can damage the surface of an uncirculated coin, lowering its grade and value instantly. Use a magnifying glass or a high-quality phone camera to inspect the torch bands and the date area. Happy hunting, and may your next pocket change discovery be a hidden gem!

FAQ
Q: Does a 1970 dime have any silver in it?
A: No. The last Roosevelt Dimes intended for circulation that contained silver were minted in 1964. The 1970 dime is made of a copper-nickel clad composition. If you see a copper-colored stripe on the edge of the coin, it is definitely not silver.
Q: Why is my 1970 dime missing a mint mark?
A: A missing mint mark on a 1970 dime simply means it was produced at the Philadelphia Mint. At that time, it was standard practice for Philadelphia not to use a “P” on the dime. It is not an error unless the coin is a “Proof” coin from a collector set.
Q: Where can I sell my 1970 Roosevelt Dime?
A: If the coin is a common circulated specimen, it is best spent as $0.10. However, if it is a high-grade MS67 or a rare error, you can sell it through reputable auction houses like Heritage Auctions, on eBay, or to local coin dealers. Using an app like CoinKnow can help you get a baseline price before you negotiate.
Q: Is a 1970-D dime worth more than a 1970 no mint mark dime?
A: Generally, no. Both the Philadelphia (no mark) and Denver (“D”) mints produced hundreds of millions of coins. Their value is almost identical and is determined by the condition (grade) of the coin rather than which mint it came from.
