The 1970-D Washington Quarter is worth anywhere from its face value of $0.25 in circulated condition to over $1,500 in high-grade mint state. Most examples found in pocket change are spending money, but specific errors and high-quality specimens can be quite valuable to collectors today.
| Condition | Estimated Value |
|---|---|
| Circulated (Average) | $0.25 – $0.50 |
| About Uncirculated (AU) | $1.00 – $3.00 |
| Uncirculated (MS-63) | $5.00 – $12.00 |
| High Grade (MS-67+) | $500 – $1,500+ |
Understanding the History of the 1970-D Washington Quarter
If you have just discovered a shiny quarter in your jar and noticed the “D” mint mark, you are looking at a piece of American history from the Denver Mint. In 1970, the United States was in the middle of the “cladded” era. This means the 1970-D Washington Quarter is not made of silver, but rather a copper-nickel composition.
Many people wonder if they should keep this coin. Since over 417 million of these were minted in Denver alone, they are very common. However, because they were mass-produced, finding one in perfect, “fresh from the mint” condition is actually quite difficult for collectors.
Before you dismiss your find as mere pocket change, consider using the best coin identifier app to see if your coin has any hidden features. Sometimes a simple quarter can hide a rare secondary minting error that isn’t visible to the naked eye at first glance.
Evaluating the 1970-D Quarter Value and Condition
The value of a 1970-D quarter depends heavily on its “grade.” Grading is a professional way of describing a coin’s wear and tear. Most coins in circulation are considered “Good” or “Fine,” meaning they have lots of scratches and smoothed-out details.
If you find a 1970-D quarter that looks like it never went into a vending machine, you might have a “Mint State” (MS) coin. Collectors value these highly because the original luster remains intact. For instance, the 1970-D Washington Quarter MS price guide shows that while a standard MS-65 coin might sell for $15, a rare MS-67 coin can fetch several hundred dollars.
For everyday Americans, identifying these grades can be tricky. That is where tools like CoinHix come in handy. By comparing your coin to high-resolution images, you can determine if your quarter is worth a trip to a professional grader or if it’s better used for laundry.
| Grade | Technical Description | Retail Value |
|---|---|---|
| Fine 12 | Heavy wear, flattened letters | $0.25 |
| EF 40 | Light wear on high points | $0.75 |
| MS 63 | Some marks, but uncirculated | $8.00 |
| MS 66 | Very clean, mirror-like luster | $55.00 |
Rare 1970-D Washington Quarter Errors to Look For
Mistakes at the mint can turn a common quarter into a valuable treasure. While the 1970-D is a clad coin, there are several known mint errors that collectors hunt for. The most famous for this year is the “Double Die” or off-center strikes.
One specific error to watch for is the “Struck on a 1969 Canadian Quarter” or other foreign planchets. In 1970, there were a few instances where quarters were struck on the wrong metal blanks. If your quarter looks thinner than usual or has a strange weight, it could be a massive win.
You should also look for “clipped planchets,” where a piece of the coin appears to be missing in a crescent shape. These errors are highly sought after in the numismatic community. To accurately check 1970 quarter market value for error coins, it is essential to weigh the coin using a digital scale to see if it deviates from the standard 5.67 grams.
Why the Mint Mark D Matters for Your Quarter
The “D” under the wreath on the back of the coin stands for Denver. During the 1970s, Denver and Philadelphia were the two main hubs for producing coins for general circulation. While San Francisco (S) produced proof versions for collectors, Denver produced the bulk of the coins used in the Midwest and West.
The 1970-D is more common than some other dates, but it remains a staple for people trying to complete a Washington Quarter album. Because many of these coins were “bagged” and stored for decades, there are still high-quality rolls out there.
If you aren’t sure if you have a “D” or a “P” (no mint mark), you can use CoinHix to zoom in and identify the mark clearly. Knowing the mint mark is the first step in unlocking the true value of your collection.
Is a 1970-D Quarter Made of Silver?
Many beginners hope their old quarters are silver. Unfortunately, the US Mint stopped using 90% silver for quarters after 1964. The 1970-D Washington Quarter is made of a “clad” composition: an inner core of pure copper and an outer layer of 75% copper and 25% nickel.
You can verify this easily by looking at the edge of the coin. If you see a copper-colored orange stripe running along the side, it is definitely a clad coin. Silver quarters will have a solid silver-colored edge.
Even though it isn’t silver, don’t throw it back into the change jar just yet. High-grade specimens are still valued by those looking for “Registry Set” coins—exceptional examples that complete a perfect collection. CoinHix can help you track these nuances and store your coin’s data digitally for future selling.

Tips for Selling Your 1970-D Washington Quarter
If you’ve determined that your quarter is a high-grade MS-66 or has a rare error, the next step is selling it. Selling a common quarter to a coin shop might only net you face value, so you need to find the right market.
Online auction sites and specialized coin forums are the best places for high-value items. Before listing, consider having the coin “certified” by a service like PCGS or NGC. A certified grade can increase the trust of a buyer and significantly bump up the final price.
Always take clear, high-resolution photos of both the front (obverse) and back (reverse). Buyers want to see the “D” mint mark clearly and assess the level of scratches for themselves. Good photography and an accurate description based on coin value apps will help you get the best price.
FAQ
Q: Is a 1970 quarter with no mint mark rare?
A: No, a 1970 quarter with no mint mark simply means it was struck at the Philadelphia Mint. These were produced in even higher quantities than the Denver versions and carry similar values—mostly face value unless in perfect condition.
Q: How can I tell if my 1970-D quarter is a “small date” or “large date”?
A: The small/large date variety is primarily associated with the 1970-S Proof quarters, not the 1970-D. If you have a Denver quarter, you don’t need to worry about this specific variety; focus on the grade and potential errors instead.
Q: What is the most expensive 1970-D quarter ever sold?
A: An exceptionally preserved 1970-D Washington Quarter graded MS-67+ by PCGS once sold for over $1,500 at auction. These high prices are only for coins that are virtually perfect with no scratches and beautiful luster.
Q: Should I clean my 1970-D quarter to make it worth more?
A: Never clean your coins! Cleaning creates microscopic scratches that professional graders can detect instantly. A cleaned coin will almost always lose its collector value and be worth only its face value of 25 cents.
