The 1950-D/S Washington Quarter is worth anywhere from $15 in heavily worn condition to well over $500 in high mint state grades — and a confirmed D/S overmintmark example can push even higher depending on the strength of the error.
If you just found one of these quarters in an old coin jar or inherited collection, you might be sitting on something genuinely interesting. This coin carries a fascinating story, a real error variety, and collector demand that keeps its value strong decades after it was struck.
What Makes the 1950-D/S Washington Quarter Special
The 1950-D/S Washington Quarter is an overmintmark variety — meaning the Denver Mint (D) stamped its mintmark over a San Francisco (S) mintmark that had already been punched into the working die. This kind of error happened occasionally in the early 1950s when the U.S. Mint reused or repurposed dies between facilities.
What you’re looking for is a faint “S” hiding beneath the bold “D” on the reverse of the coin, just to the right of the eagle’s tail feathers. Under a loupe or magnifier, you can usually see the remnants of the underlying S shape peeking through.
Not every 1950-D quarter is a D/S variety, so it’s worth inspecting carefully. If you want a quick first look, try a free coin identifier app to see what you’re working with before spending money on a professional opinion.
1950-D/S Washington Quarter Value by Grade
The value of this coin depends heavily on its condition. Coin collectors use a 70-point Sheldon scale, where lower numbers mean heavy wear and higher numbers mean near-perfect surfaces. Here’s a general breakdown of what the 1950-D/S Washington Quarter is worth across different grades:
| Grade | Condition Description | Estimated Value |
|---|---|---|
| G-4 (Good) | Heavy wear, outline visible | $15 – $25 |

| EF-40 (Extremely Fine) | Light wear on high points | $75 – $150 |
| MS-63 (Mint State) | Uncirculated, minor contact marks | $200 – $350 |

How to Check If Your Coin Is the D/S Variety
Start by finding the mintmark on the reverse side — it’s located just above the quarter’s date area near the bottom of the coin. You’ll need at least a 5x magnifier or a jeweler’s loupe to see the overmintmark detail clearly.
The key thing to look for is a serif or curved bottom of an “S” shape poking out from beneath the “D.” The strength of the underlying S varies from coin to coin — some are obvious, others are subtle. A strong, clearly visible S beneath the D will carry significantly more collector premium.
If you’re still unsure, CoinHix has a visual guide and community resources that can help you compare your coin to known examples. Getting a second opinion before selling is always smart.
Should You Get It Graded?
If your 1950-D/S Washington Quarter looks uncirculated or shows strong eye appeal, professional grading through PCGS or NGC is worth considering. A graded MS-64 or higher example in a certified slab sells for considerably more than a raw coin of similar quality — buyers simply trust graded coins more.
The cost of grading runs roughly $30–$50 per coin for standard submissions. That fee makes sense when the coin has a realistic shot at grading out at MS-63 or better, where values start climbing past $200. For circulated examples in VF or lower, grading costs may exceed the coin’s value, so save that step for cleaner pieces.
You can also get a quick sense of your coin’s likely value range by reviewing detailed 1950 Washington Quarter value estimates by grade and mintmark before deciding whether professional certification makes financial sense.
Tips for Selling Your 1950-D/S Washington Quarter
If you’re ready to sell, your best options are established coin dealers, online auction platforms like eBay or Heritage Auctions, and coin shows. Confirmed D/S variety coins tend to attract specialist collectors, so listing it in a numismatic community with the variety clearly identified will get you better results than a generic listing.
Always photograph both sides in good lighting, and if possible, include a close-up of the mintmark area showing the overmintmark. Buyers want proof of the variety, especially for online sales.
Using CoinHix to monitor recent sold prices gives you real leverage in negotiations — you’ll know exactly what the market is paying instead of guessing.

FAQ
Q: How do I know if my 1950-D quarter is the D/S overmintmark variety?
A: Look at the mintmark on the reverse under magnification. If you can see the curved elements of an “S” beneath the “D,” you likely have the D/S variety. A jeweler’s loupe at 5x or higher works well for this inspection.
Q: Is the 1950-D/S Washington Quarter rare?
A: It’s considered a collectible variety rather than a true rarity. Enough examples exist that collectors can find them, but the combination of condition and clear overmintmark visibility keeps demand and value strong among specialists.
Q: What is the silver content of the 1950-D/S Washington Quarter?
A: Like all Washington Quarters made before 1965, this coin is composed of 90% silver and 10% copper. The silver melt value alone is typically around $4–$5 depending on the current silver spot price, though the collector value far exceeds melt in most grades.
