The 1976-S Washington Quarter is worth anywhere from $1.50 in uncirculated condition to over $15,000 for rare high-grade silver specimens. While billions of Bicentennial quarters were minted for the nation’s 200th anniversary, those bearing the “S” mint mark from San Francisco hold a special place in collectors’ hearts.
| Condition/Type | Estimated Value |
|---|---|
| 1976-S Clad Proof | $2 – $10 |
| 1976-S Silver Uncirculated | $5 – $25 |
| 1976-S Silver Proof (Deep Cameo) | $15 – $100+ |
| Rare Mint Errors | $200 – $1,000+ |
Understanding the 1976-S Bicentennial Quarter Basics
If you have found a quarter featuring a colonial drummer on the back and the dual dates “1776-1976” on the front, you have a Bicentennial quarter. While the “P” (Philadelphia) and “D” (Denver) versions are extremely common in pocket change, the “S” mint mark indicates the coin was produced at the San Francisco Assay Office. These were specifically minted for collectors and were not intended for general circulation.
To quickly determine if your find is a diamond in the rough, many hobbyists use a top coin identifier app to scan the surface for specific markings. The 1976-S quarters come in two distinct metal compositions: copper-nickel clad and 40% silver. Identifying which one you have is the first step in determining its market worth.
Because these were sold in special sets, most 1976-S quarters remain in excellent condition. However, if you found one in a jar of spare change, it likely suffered some wear, which significantly impacts the price. Using a tool like CoinKnow can help you evaluate the strike quality and luster right from your smartphone.

The Difference Between Clad and Silver 1976-S Quarters
The San Francisco Mint produced both copper-nickel “clad” versions and a special 40% silver alloy version of the Bicentennial quarter. The clad versions were included in 1975 and 1976 Proof Sets, while the silver versions were sold in three-piece Uncirculated or Proof sets along with the Bicentennial half dollar and dollar.

Distinguishing between the two is vital. Look at the edge of the coin; if you see a solid silver stripe with no visible copper core, you likely have the 40% silver version. The silver version weighs 5.75 grams, whereas the clad version weighs 5.67 grams. If you are unsure, checking the current market prices for 1976 clad quarters can give you a baseline for the more common varieties.
Collectors highly prize the silver versions because they represent the last time the U.S. Mint used silver for circulating-style denominations until the modern “Silver Proof” era began in 1992. The CoinKnow app features a database that helps users distinguish these metal types based on visual cues and weight.

Grading and Quality: Why Some 1976-S Quarters Are Worth Thousands
In the world of coin collecting, the “Grade” is everything. Coins are graded on a scale from 1 to 70. A 1976-S quarter in a “Proof 65” or “Mint State 65” condition is worth a few dollars. However, if the coin is graded at a perfect PR70 or MS70, the price can skyrocket into the thousands.
For the 1976-S silver quarter, the auction record stands at over $19,000 for a perfect specimen. This is because achieving a flawless surface on these coins was difficult during the minting process. Most collectors will find coins in the PR67 to PR69 range, which are beautiful but far more common. You can find detailed 1776-1976 quarter value information regarding high-grade sales on specialized numismatic trackers.
When examining your coin, look for “Deep Cameo” (DCAM) effects. This is where the frosted portrait of George Washington and the Drummer on the back contrast sharply against a mirror-like background. Use CoinKnow to browse high-resolution images of various grades so you can compare your coin to known museum-quality examples.

Rare 1976-S Error Varieties to Look For
While most 1976-S Washington quarters are valued for their condition, some are valuable because of mistakes made at the Mint. Mint errors are highly sought after by specialists and can turn a common quarter into a $500 treasure.
One rare error involves the wrong planchet. Occasionally, a 1976 quarter was struck on a silver planchet intended for a different coin, or a clad quarter was accidentally struck on a silver planchet meant for the collector sets. These “transitional” errors are extremely rare.
Other errors include “Double Dies,” where the letters or numbers appear doubled, and “Off-Center” strikes. If you notice your 1976-S looks “weird” or has distorted text, do not clean it! Cleaning a coin destroys its value. Instead, use a magnifying glass or a digital microscope to see if the doubling is distinct.

How to Sell and Store Your 1976-S Collector Coin
Once you’ve identified your 1976-S quarter’s value, you need to protect it. Exposure to air and oils from your fingers can tarnish silver and dull the “proof” finish of a clad coin. Store your quarters in PVC-free plastic holders or “flips.”
When it comes time to sell, your best bet for a standard 1976-S proof coin is an online marketplace like eBay or a local coin shop. However, if you believe you have a grade 69 or 70 coin, or a significant error, you should consider professional grading services like PCGS or NGC. A certified coin always commands a higher price than an “unprocessed” one.
Before visiting a dealer, check current auction trends on CoinKnow to ensure you aren’t accepting an under-market offer. Knowledge is power in the numismatic world, and having a digital guide in your pocket ensures you get a fair price for your Bicentennial piece.
FAQ
Q: Is every 1776-1976 quarter rare?
A: No. Over 1.6 billion Bicentennial quarters were produced. Most “P” and “D” mint marks found in change are only worth 25 cents. Only the “S” mint marks, silver versions, and rare high-grade or error coins carry significant premiums.

Q: How can I tell if my 1976-S quarter is silver without a scale?
A: You can perform the “tissue test.” Place a piece of single-ply toilet tissue over your coin alongside a regular modern quarter. Through the tissue, a 40% silver coin will appear white or bright, while a clad coin will appear dark or grayish. You can also look at the edge; silver coins have no copper stripe.
Q: What is the “S” mint mark?
A: The “S” stands for the San Francisco Mint. In 1976, this mint only produced coins for collectors (Proof Sets and Silver Uncirculated Sets), which is why 1976-S quarters are generally more valuable than those from Philadelphia or Denver.
Q: Should I clean my 1976-S quarter to make it shine?
A: Absolutely not! Cleaning a coin with chemicals or cloths creates micro-scratches that professional graders can see. Cleaning can reduce a coin’s value by up to 90%. Always keep the coin in its original “as found” condition.
