1970 Washington Quarter Value: Is Your No Mint Mark Coin Rare?
The 1970 Washington Quarter is worth anywhere from its face value of $0.25 in worn condition to over $30 in high-grade uncirculated condition. While most are common pocket change, specific errors and high-quality specimens can fetch hundreds or even thousands of dollars at auction.
| Condition / Grade | Estimated Value |
|---|---|
| Circulated (Good to About Uncirculated) | $0.25 – $0.50 |
| Uncirculated (MS60 – MS63) | $1.00 – $3.00 |
| Gem Uncirculated (MS65 – MS67) | $10.00 – $45.00 |
| Exceptional Grade (MS68+) | $500+ (Auction Records) |
| 1970 Quarter Error Coins | $20 – $2,500+ |
Understanding the 1970 Washington Quarter No Mint Mark
If you are looking at a 1970 quarter and notice there is no small letter next to Washington’s ponytail, you have a coin minted in Philadelphia. During this era, the Philadelphia Mint did not use a “P” mint mark on quarters. For most everyday Americans, finding one of these in a jar of change is a common occurrence. To quickly determine if yours is a rare variety, you can use a free coin identifier app to scan the details of the coin’s surface.
Unlike older quarters from 1964 and earlier, the 1970 issue is not made of silver. It is a “clad” coin, consisting of a copper core sandwiched between layers of cupronickel. This means it doesn’t have intrinsic bullion value. However, collectors still hunt for them to complete their sets. Using CoinKnow can help you distinguish between a regular strike and a high-grade specimen that might be worth more than a few cents.
Philly minted over 417 million of these quarters in 1970. Because the mintage was so high, only coins in “Mint State” (MS) condition usually carry a premium. If your coin looks like it just came from the bank—shiny, with no scratches or wear on Washington’s hair—it might be worth grading. You can check the latest 1970 Washington quarter price data for Mint State grades to see how much a professional certification could increase its market value.
Factors That Influence 1970 Philadelphia Quarter Value
The value of a 1970 Washington quarter is primarily driven by its condition, also known as its “grade.” Most coins found in circulation are graded between “Good” and “Extra Fine.” At these levels, they are only worth 25 cents. However, collectors focus on “Uncirculated” coins that have never been used in commerce.
Surface preservation is key. When a coin is minted, it has a natural “luster” or shine. Over time, as it clinks against other coins, it develops “bag marks” or scratches. Coins with very few marks and a strong strike are rare. If you find a coin that looks perfect, CoinKnow can help you compare it to known high-grade examples.
Another factor is the “eye appeal.” Some coins develop a beautiful toning or color over time due to oxidation. While most 1970 quarters stay a dull silver color, those with rainbow toning can fetch a massive premium at specialized auctions. Understanding the current market value of 1970 quarters across different conditions is essential before you decide to sell.
| Grade Designation | Description | Estimated Market Price |
|---|---|---|
| MS63 | Typical strike with moderate marks | $2 – $5 |
| MS65 | Gem quality with great luster | $15 – $25 |
| MS67 | Near perfect, very rare for this year | $80 – $150 |
| MS67+ | Museum quality strike | $500+ |
The Infamous 1970-S Proof Quarter Error
While we are focusing on the “No Mint Mark” quarters from Philadelphia, it is impossible to talk about 1970 quarters without mentioning the most famous error of the decade. This error actually occurred on a coin with an “S” mint mark (from San Francisco), but it is often confused by beginners.
In 1970, some proof quarters were accidentally struck over 1941 Canadian quarters. This resulted in a “dual-design” coin where you can faintly see Canadian details behind the image of George Washington. These coins are incredibly rare and have sold for over $35,000.
If you have a 1970 quarter that looks “wrong”—perhaps the edges are different or you see ghost-like numbers from a different year—you need to have it appraised. While the Philly “No Mint Mark” coins don’t usually have this specific error, they can have “Double Die” or “Off-Center” strikes that are also very valuable. Using an app like CoinKnow helps enthusiasts identify these subtle minting mistakes.
Identifying Doubled Die and Mint Errors
Beyond the standard grade, “error” collectors look for 1970 quarters with production mistakes. The most common error to look for on a 1970 Philadelphia quarter is the “Doubled Die Obverse” (DDO) or “Doubled Die Reverse” (DDR). This happens when the die used to stamp the coin has a doubled image.
On a 1970 quarter, look closely at the words “IN GOD WE TRUST” or the date. If the letters look like they have a faint second layer or “shadowing,” you might have a doubled die. These aren’t the million-dollar errors, but they can easily turn a 25-cent coin into a $50 specialized item.
Other errors include:
– Off-Center Strikes: Where the coin design is not centered on the metal disk.
– Die Cracks: Raised lines of metal caused by a broken stamp.
– Clad Layer Issues: Where the nickel outer layer peels off to reveal the copper core.
| Error Type | What to Look For | Potential Value |
|---|---|---|
| 10% Off-Center | Design shifted to one side | $20 – $40 |
| 50% Off-Center | Half the coin is blank metal | $150 – $300 |
| Broadstruck | Coin is wider and flatter than normal | $15 – $30 |
| Double Die Obverse | Doubling on the date or “LIBERTY” | $25 – $100+ |
Comparing the 1970 No Mint Mark to Other 1970 Quarters
It is helpful to know where your coin fits in the larger 1970 production run. There were three main “types” of quarters produced that year. Understanding the differences will help you realize why the “No Mint Mark” version is the most common one found in your pocket.
First, there is the 1970 Philadelphia (No Mint Mark), with 417 million coins. Second is the 1970-D (Denver) quarter, which has a small “D” and saw a mintage of about 136 million. Finally, there is the 1970-S Proof, which was made specifically for collectors and usually has a mirror-like finish.
Interestingly, while Denver had a lower mintage, the Philadelphia coins often have more value in the highest “Mint State” grades because they were struck with older dies, making crisp, perfect examples rarer. If you find a 1970-D or a 1970 No Mint Mark that looks like it’s brand new, it is worth putting in a protective sleeve immediately.
How to Sell Your 1970 Washington Quarter
If you believe you have found a high-value 1970 quarter, the next step is knowing how to sell it. For coins worth less than $10, local coin shops or eBay are your best bets. However, if the coin is an MS67 or better, or has a significant mint error, you should consider professional grading by services like PCGS or NGC.
Before spending money on grading fees, which can cost $30-$50 per coin, use a digital tool to verify your findings. High-quality photos sent to online forums or analyzed through a coin app can save you money. Always handle your coins by the edges to avoid leaving fingerprints, as the oils from your skin can damage the luster and lower the grade (and the value) significantly.
The coin market fluctuates, but “cherrypicking”—the act of finding rare coins in bulk piles—remains a popular hobby. The 1970 quarter might seem boring at first glance, but for those with a keen eye for errors and condition, it can be a rewarding find.
FAQ
Q: Does a 1970 quarter with no mint mark contain silver?
A: No, the 1970 Washington Quarter is a clad coin made of copper and nickel. The U.S. Mint stopped making circulating silver quarters after 1964. If your 1970 coin looks silver on the edge with no copper stripe, it might be a rare error or a plated coin, but it was not intended to be silver.
Q: Why is my 1970 quarter worth only 25 cents?
A: Because over 400 million were minted in Philadelphia alone, they are very common. Unless the coin is in perfect, uncirculated condition or has a recognized mint error, collectors can easily find them for face value.
Q: What is the most valuable 1970 quarter ever sold?
A: The record is held by a 1970-S Proof quarter struck over a 1941 Canadian Quarter, which sold for over $35,000. For the “No Mint Mark” Philadelphia quarters, the record for a near-perfect MS67+ grade reached over $2,000 at auction.
Q: Where is the mint mark located on a 1970 quarter?
A: On the 1970 quarter, the mint mark is located on the “heads” side (obverse), to the right of George Washington’s ponytail. If that area is blank, it was minted in Philadelphia. If it has a “D,” it’s from Denver; if it has an “S,” it’s a Proof coin from San Francisco.
