The 1950-S/D Washington Quarter is worth anywhere from $6 in worn condition to over $15,000 for high-grade specimens of the famous “S over D” mint mark error. This specific year is a favorite among collectors because it contains 90% silver and hides one of the most famous “over-mintmark” errors in the entire Washington series.
| Condition / Grade | 1950-S Value (Standard) | 1950-S/D Error Value |
|---|---|---|
| Good to Fine (Circulated) | $6 – $10 | $150 – $350 |
| Extremely Fine (XF 45) | $12 – $15 | $400 – $600 |
| Uncirculated (MS 63) | $25 – $35 | $800 – $1,200 |
| Superb Gem (MS 66+) | $150+ | $5,000 – $15,000+ |
Identification Features of the 1950 Washington Quarter
If you have just found a silver quarter in a jar or an old collection, the first step is to identify where it was made. In 1950, the United States Mint produced quarters at three locations: Philadelphia (no mint mark), Denver (D), and San Francisco (S). To find the mint mark, look at the reverse side of the coin, right below the center of the wreath that the eagle is perched upon.
Finding a coin with an “S” is usually preferred by collectors because San Francisco generally had lower production numbers. However, the 1950-S/D Washington Quarter Value is significantly higher because of a production mistake. To see if your coin is a winner, you can use a top coin identifier and value app to get an instant digital appraisal. Accuracy is key when dealing with coins that might be worth hundreds of dollars.
When inspecting your coin, pay attention to the luster. A coin that has never been in a pocket or cash register will have a “cartwheel” effect when rotated under a light. These Uncirculated coins carry the highest premiums. If your coin looks dull or smooth, it has “circulated,” but because it is silver, it still maintains a baseline “melt value.” Tools like CoinKnow can help you determine the difference between a common silver coin and a collector’s prize.

Understanding the 1950-S Over D Mint Mark Error
The 1950-S/D is what numismatists call an “Over-Mintmark” (OMM) error. During the die-making process at the Philadelphia Mint, a punch for the “S” mint mark was hammered directly over a pre-existing “D” mint mark. This resulted in a coin where parts of the letter “D” are visible underneath or beside the letter “S.” It is one of the most recognizable errors in 20th-century American coinage.
Because this error is rare, many people use magnifying glasses to look for a small curve sticking out from the top or left side of the “S.” If you suspect you have one, checking the current auction prices for 1950-S MS quarters will show you that even a small visual difference can result in a price jump of several hundred dollars. Collectors are willing to pay a massive premium to complete their error sets.

The demand for the 1950-S/D has remained steady for decades. Unlike some modern “doubled dies” that require a microscope to see, a well-preserved S-over-D can be spotted with a standard jeweler’s loupe. This accessibility makes it a “holy grail” for casual hunters. Using CoinKnow allows you to compare high-resolution photos of the error to your own coin to ensure you aren’t looking at mere “die chips” or damage.
Grading and Condition: How It Impacts Price
Coin grading is the process of determining how much wear and tear a coin has suffered. For the 1950 Washington Quarter, the grade is the most important factor after the mint mark. Most coins found in circulation are graded “Good” to “Very Fine.” These are valued primarily for their silver content, which is 0.1808 troy ounces of pure silver.

For those interested in high-end collecting, the 1950 silver quarter value guide highlights the massive price gap between an MS 65 and an MS 67 grade. Professional grading services like PCGS or NGC use a 70-point scale. A single scratch on Washington’s cheek can drop a coin from a $500 value to a $50 value.
| Grade Designation | Description | Estimated Value (1950-D) |
|---|---|---|
| About Uncirculated (AU) | Slight wear on the highest points (hair/eagle’s breast). | $8 – $12 |
| Mint State 63 (MS 63) | No wear, but several small marks or scuffs. | $20 – $30 |
| Mint State 65 (MS 65) | Strong luster and only minor distracting marks. | $45 – $60 |
| Mint State 67 (MS 67) | Virtually perfect to the naked eye. Rare for this year. | $400+ |
Silver Content vs. Numismatic Value
Even if your 1950 quarter is heavily worn and does not have the S/D error, it is still worth much more than 25 cents. All Washington Quarters minted between 1932 and 1964 are composed of 90% silver and 10% copper. When the price of silver rises, the “junk silver” value of these coins rises accordingly. This creates a “floor” for the price.
As of recent market trends, a common 1950 quarter is worth roughly $5 to $6 just for its metal content. Many investors buy these in bulk as a hedge against inflation. For the everyday person, this means you should never spend these at a grocery store! Instead, use CoinKnow to track the current spot price of silver and see how it affects your collection’s total worth.

It is helpful to keep a running tally of your silver coins. While a single quarter might only buy you a coffee, a roll of 40 silver quarters is worth over $200. Always check the date and mint mark before selling them for scrap, as you wouldn’t want to accidentally sell a rare 1950-S/D at the price of common silver.
Collecting the 1950-D and 1950 Philadelphia Quarters
While the 1950-S/D gets all the headlines, the standard 1950 (P) and 1950-D quarters are also important for set collectors. The Denver Mint (D) produced over 21 million quarters in 1950, making it relatively common. The Philadelphia Mint produced about 24 million. Because these numbers are high, these coins are very affordable for beginners.
If you are looking to start a “Date and Mint Mark” set, the 1950 series is a great place to begin because you can find attractive, shiny examples without spending a fortune. Unlike the coins of the 1930s, 1950 quarters were often saved in rolls by banks, meaning many “Brilliant Uncirculated” examples survived.

How to Sell Your 1950 Quarter for the Best Price
Once you’ve identified a potentially valuable coin, you might be wondering how to turn it into cash. For common silver quarters, local coin shops are usually the easiest option. They will pay you a percentage based on the silver spot price. However, if you believe you have a high-grade 1950-S or the S/D error, you should take a different approach.
Selling rare errors on platforms like eBay or through specialty auction houses can yield much higher returns. Before listing, consider getting the coin “certified” by a professional grading service if it appears to be in Mint State. This adds a level of trust for the buyer. Many enthusiasts use the CoinKnow app to find local dealers or to research recent “sold” listings to ensure they aren’t getting low-balled.
Be wary of cleaning your coins. One of the biggest mistakes a beginner can make is trying to “shine up” an old quarter with baking soda or polish. This creates microscopic scratches that professional graders can see instantly. A cleaned coin can lose up to 50% or more of its numismatic value. Leave the patina exactly as it is; collectors actually prefer the natural “toning” that develops over decades.
FAQ
Q: How can I tell if my 1950-S quarter is the S/D error?
A: You will need a magnifying glass. Look closely at the “S” mint mark on the back. If you see a small vertical line or part of a curve inside or slightly to the left of the “S,” it is likely the “S over D” variety. Using a high-resolution coin app can help you compare your coin to known error samples.

Q: Is every 1950 quarter made of silver?
A: Yes, all quarters minted for circulation in 1950 are 90% silver. The US transition to copper-nickel “clad” quarters did not happen until 1965. If it’s dated 1950, it contains precious metal.
Q: What is the highest price ever paid for a 1950-S/D quarter?
A: High-grade examples of the S/D error in MS 67 condition have sold for over $15,000 at major auctions. Standard 1950-S quarters in similar top-tier grades can sell for several hundred dollars, but the error is the true prize.
Q: Where is the mint mark on a 1950 quarter?
A: The mint mark is located on the reverse (back) side of the coin. Look at the bottom, directly below the eagle’s tail feathers and above the “R” in the word “QUARTER.” If there is no letter, it was minted in Philadelphia.
