The 1988-D Washington Quarter is worth anywhere from its face value of $0.25 in circulated condition to over $400 in high-grade mint state.

History and Specifications of the 1988-D Washington Quarter
If you have found a 1988-D quarter in your spare change, you are looking at a piece of American history from the late 20th century. By 1988, the Denver Mint was producing billions of coins to keep up with the demands of a booming economy. For everyday Americans, using a top coin identifier and value app is the fastest way to determine if their “D” mint mark quarter is just a regular spender or a potential collectible.
The 1988-D quarter features the classic portrait of George Washington designed by John Flanagan. This design was first introduced in 1932 to commemorate the 200th anniversary of Washington’s birth. Unlike the quarters minted before 1965, the 1988 version contains no silver. It is composed of a “clad” sandwich: a core of pure copper with outer layers made of 75% copper and 25% nickel.
When you use an app like CoinKnow, you can quickly see the technical specs. The coin weighs 5.67 grams and has a diameter of 24.3 mm. Because over 566 million of these were struck at the Denver Mint alone, they are very common in circulation. However, “common” does not mean “worthless” if the condition is exceptional. Many collectors use CoinKnow to track the market moving prices of these late-80s issues.

Understanding the 1988-D Quarter Value by Grade
To find out what your coin is worth, you must first look at its “grade.” Grading is a system used by numismatists to describe how much wear and tear a coin has suffered. Most 1988-D quarters you find in your wallet are “Circulated,” meaning they have scratches and smoothed-out details from being touched by thousands of hands and clinking against other coins. In this state, they remain worth exactly 25 cents.
However, if you happen to find a roll of uncirculated coins or a set that has been tucked away in a drawer since 1988, you might have a “Mint State” (MS) coin. These are coins that never entered public circulation and still have their original “mint luster”—that frosty, shiny glow that reflects light in a cartwheel pattern. For those looking for precise data, the 1988-D quarter auction prices show a massive jump in value once you reach the MS67 grade level and above.

Professional grading services like PCGS or NGC use a 70-point scale. A grade of MS60 is a basic uncirculated coin, while MS70 is perfection. Most 1988-D quarters top out at MS65 or MS66. Finding one in MS67 or higher is extremely difficult because of how these coins were handled during the high-speed minting process at the Denver facility.
| Grade Level | Key Characteristics | Avg. Market Price |
|---|---|---|
| MS63 | Light marks, good luster | $1 – $3 |
| MS65 | Few marks, very attractive | $10 – $25 |
| MS66 | Very clean, intense luster | $40 – $75 |
| MS67 | Nearly perfect to naked eye | $150 – $300 |
Identifying Rare 1988-D Quarter Errors
One way a standard “pocket change” coin becomes valuable is if it has a mint error. Errors occur when something goes wrong during the manufacturing process. For the 1988-D Washington Quarter, collectors look for specific anomalies that can turn a 25-cent coin into a $50 or $100 prize. Some common errors found in this era include “Off-Center Strikes,” where the coin blank was not aligned properly, resulting in a partial image.

Another interesting error is the “Double Die.” While a major 1988-D doubled die obverse is not widely recognized as a “holy grail” like the 1955 penny, minor doubling can often be spotted on the lettering or the date. If the letters look like they have “shadows” or extra thickness, you might have a doubled die. Using CoinKnow can help you compare your coin against photos of known error types.
“Die cracks” and “Cuds” are also popular among hobbyists. These look like raised blobs of metal on the surface of the coin where the steel die used to stamp the image actually cracked or broke. Because the Denver Mint pushed their equipment to the limit to meet production quotas in 1988, these mechanical errors are more common than you might think. Checking the 1988-D quarter error value guide can give you a better idea of what specific mistakes are currently trending in the market.
Why the Denver Mint Mark Matters
In the world of American coinage, the small letter “D” located to the right of George Washington’s ponytail (on the obverse side) indicates that the coin was struck in Denver, Colorado. In 1988, the Philadelphia Mint also produced quarters, which bear the “P” mint mark. Usually, one mint produces fewer coins than the other, making one slightly more “rare” than the other in high grades.

For 1988, Denver produced 566,227,487 quarters, while Philadelphia produced 562,052,000. Because the numbers are so similar, neither is inherently rarer than the other in terms of total volume. However, the quality of the strike can vary. Many collectors believe the Denver Mint produced slightly “mushier” strikes in the late 80s, making a sharp, well-defined 1988-D quarter more desirable for those trying to complete a registry set.
If you find a quarter with no mint mark at all, it was likely struck in Philadelphia (though in 1988, “P” was standard for Philly quarters). Always zoom in on that small area near the “In God We Trust” motto to be sure of what you have. A clear, crisp “D” is what you want to see if you are hunting for Denver-specific errors.
Where to Sell Your 1988-D Washington Quarter
If you’ve checked your coin and believe it’s a high-grade specimen or a rare error, your next question is likely: “Where do I sell it?” For most circulated quarters, the best place is simply the grocery store—since they are only worth 25 cents. But if you have something special, you have several options.

Local coin shops are great for quick evaluations, though they generally only buy coins that have a retail value of at least a few dollars. Online marketplaces like eBay are the most popular spot for everyday people to sell errors or “Uncirculated” coins. When listing on eBay, make sure to take high-quality, clear photos of both sides of the coin.
For coins that you believe are worth hundreds of dollars (MS67 or higher), you should consider professional grading by PCGS or NGC. A coin in a “slab” (a protective plastic holder with a certified grade) sells for much more than a “raw” coin because the buyer has a guarantee of its authenticity and quality.
| Selling Venue | Pros | Cons |
|---|---|---|
| Local Coin Shop | Instant cash, expert advice | Lower payout (wholesale prices) |
| eBay | Largest buyer pool | Fees and shipping hassle |
| Auction Houses | Best for high-value items | Only for coins worth $500+ |
FAQ: Common Questions About the 1988-D Quarter
##
Q: Is a 1988-D quarter made of silver?
A: No. Any Washington quarter dated 1965 or later is made of a copper-nickel clad composition. The last business-strike silver quarters were minted in 1964. The only exception would be special silver proof sets issued for collectors, but those would not have a “D” mint mark (they have an “S” for San Francisco).

Q: What is the highest price ever paid for a 1988-D quarter?
A: The record price for a 1988-D Washington Quarter is approximately $400 – $600 for a specimen graded MS68 by PCGS. These are incredibly rare and represent the absolute best examples ever produced by the mint that year.
Q: How can I tell if my 1988-D quarter is “Uncirculated”?
A: Look for “mint luster.” If the coin has a shiny, frost-like appearance when you rotate it under a light, it may be uncirculated. If the surfaces look dull, grey, or have many tiny scratches, it is a circulated coin worth face value.
Q: Is there a 1988-D “repunched mint mark” error?
A: There are some minor repunched mint marks (RPMs) known for the 1988-D series, where the “D” looks like it was stamped twice. While interesting to specialists, these usually only add a few dollars to the coin’s value unless the coin is also in perfect condition.
