Try the Calculator →The 1950-D/S (FS-601) is the most famous Washington Quarter variety. A Denver "D" was punched directly over a die that already bore a San Francisco "S" — and every coin struck from that die shows the residual "S" beneath the "D." Use this checker to see if your D-mint coin might qualify.
The table below covers all major varieties across four condition tiers. For a fully illustrated, step-by-step 1950 quarter identification walkthrough and complete reference, see this in-depth 1950 Washington quarter breakdown with identification guide. Signature variety (D/S OMM) is highlighted in gold; the rarest (Proof DCAM) in red.

The 1950 Washington Quarter series is unusually rich in die variety errors. The post-war resumption of normal mint operations created conditions where mint mark punches were misapplied — producing the legendary Over-Mint Mark varieties — and hub doubling occurred during die preparation at all three minting facilities. Each card below covers a distinct variety with diagnostic details, value ranges, and collector notes.
The 1950-D/S is arguably the single most celebrated variety in the entire Washington Quarter series. It occurred when a working die originally intended for the San Francisco Mint — and already punched with an "S" mint mark — was redirected to Denver and repunched with a "D." The result is a "D" mint mark with the curved remnants of an underlying "S" visible to its upper-left under magnification.
Identifying this variety requires a 5–10× loupe focused on the mint mark on the reverse, just below the eagle. The diagnostic feature, as described in the Cherrypickers' Guide (Fivaz and Stanton), is the partial upper-left curve of the "S" protruding above and to the left of the "D" serif. The underlying "S" appears strongest in the upper curve, not within the body of the "D."
Collectors prize this variety across all grades, making it extremely rare in high mint state. Even worn circulated examples command strong premiums. The spread between a common 1950-D and this variety is dramatic at every grade level, from $40 worn to nearly $30,000 in gem condition.
The mirror variety to the famous D/S, the 1950-S/D arose when the opposite error occurred at San Francisco: a working die originally punched with a Denver "D" was redirected to San Francisco and repunched with an "S." Per PCGS, the underlying "D" is boldly exhibited below the "S" mint mark, making this variety among the most diagnostically clear of all Washington Quarter over-mint-marks.
On the reverse, below the eagle, the "S" mint mark shows an obvious secondary impression of the "D" below it — visible with a 5× loupe or even, on the best examples, with the naked eye. The lower serif and vertical stroke of the "D" are the primary diagnostics, appearing just below the bottom curve of the "S."
While less well-known than its D/S counterpart, the 1950-S/D is equally scarce in mint state and commands premium prices at every grade level. Many collectors consider this variety more diagnostically satisfying than the D/S because the underlying "D" is so boldly evident. It was cataloged by CONECA and listed in the Cherrypickers' Guide as FS-601 for the San Francisco issue.
The 1950 Philadelphia DDR FS-801 is a working-die variety caused by a misaligned second hub impression during reverse die preparation at the Philadelphia Mint. The die received two slightly offset impressions from the master hub, causing a shadow or separation effect on the reverse design elements — particularly the inscriptions.
The doubling is most evident in the reverse lettering "UNITED STATES OF AMERICA" and "QUARTER DOLLAR." Under a 5–10× loupe, individual letters show a clear secondary, offset shadow impression just adjacent to the primary strike. This separation distinguishes DDR varieties from machine doubling, which produces a flat, shelf-like appearance rather than a true incuse secondary image.
This variety is more affordable and accessible than the over-mint-mark errors, making it an excellent entry point for collectors interested in 1950 Washington Quarter varieties. Greysheet lists the value range from $35 in lower grades to $650 in gem mint state, reflecting solid but moderate collector demand. Every coin struck from this affected die shows the doubling consistently.
The Denver Mint produced at least two distinct Doubled Die Reverse varieties in 1950, designated FS-801 and FS-802 in the Cherrypickers' Guide. Both arose from misaligned hub impressions during reverse die preparation at Denver — the same mechanical cause as the Philadelphia DDR, but producing a different doubling pattern due to slight differences in die rotation and hub impression strength.
NGC notes that one of the Denver DDR varieties is "quite pronounced," making it identifiable under moderate magnification. The doubling appears most strongly in the upper rim lettering and in the eagle's details — the wing tips, breast feathers, and the arrows held in the eagle's left talon. FS-802 is generally regarded as showing stronger doubling than FS-801 and is correspondingly scarcer and more valuable.
Greysheet CPG values list these at $340 and $430 respectively, reflecting their relative accessibility compared to the over-mint-mark varieties. Identifying which specific variety (801 or 802) you have requires careful comparison against published plate photographs in the Cherrypickers' Guide or confirmation from a PCGS or NGC VarietyPlus designation on the holder.
The 1950-S/S RPM FS-501 is a San Francisco Mint variety in which the "S" mint mark punch was applied to the working die twice, at slightly different positions. Before 1990, all U.S. mint marks were hand-punched individually into each working die rather than being included in the master hub. This manual process made repunched mint mark varieties common across the era, though only select examples are listed in the Cherrypickers' Guide as distinct, confirmed varieties.
On this specific variety, the secondary "S" impression is visible overlapping or adjacent to the primary "S," creating a doubled or shadowed mint mark appearance. The result is a mint mark that appears thickened, off-center, or shows a secondary letter either above, below, or beside the primary punch. Examination under a 5–10× loupe is necessary to distinguish true RPM from a die deterioration doubling.
The 1950-S/S RPM FS-501 offers collectors an affordable entry into 1950-S Washington Quarter varieties. Greysheet CPG lists it at $235 in the available grade range, while CoinValues.com suggests approximately $75 for accessible circulated examples. This variety rewards careful cherry-picking — many examples are likely unattributed in collections or dealers' stock as plain 1950-S quarters.

Washington's hair above the ear is flattened and merges with the field. The cheekbone is smooth and dull. On the reverse, the eagle's breast feathers have largely merged into a flat surface. Lettering is readable but lacks depth. Value is essentially silver melt: $15–$18.
High points on Washington's cheek and the hair above the ear show visible wear, but major design details are still present. Eagle breast feathers show definition in protected areas. Under a light, most of the coin's field still shows mint luster in XF; about 75% luster remains at AU. Value: $18–$22.
No wear anywhere on the coin. Tilt under a single light source — cartwheel luster flows across the entire surface including the cheek and breast feathers with no flat spots. Contact marks (bag marks from mint handling) are acceptable through MS-63; MS-64 shows fewer marks; MS-65 has only minimal marks. Value: $20–$55.
Exceptional surface preservation with nearly no contact marks even under magnification. Luster is vibrant and complete. Washington's cheek and the eagle's breast are virtually pristine. MS-67 specimens are condition rarities for all three mints. MS-68 examples are extraordinarily rare and have brought four to five figures at auction. Value: $50–$19,800+.

The right venue depends on what you have. A common circulated example sells fastest online for silver melt. A D/S Over-Mint Mark or high-grade gem needs a specialist audience that can recognize and pay for the premium.
The premier venue for high-grade and variety 1950 quarters. Heritage has sold the top auction records for this date — including the $31,200 DCAM proof and the $29,375 D/S MS-67. Best for: D/S or S/D OMM varieties, MS-66+ business strikes, and any proof coin. Expect 15–20% buyer's premium; consignment fees apply.
Excellent for circulated and mid-grade uncirculated 1950 quarters reaching a large audience of silver buyers and Washington quarter collectors. Check recently sold 1950 Washington quarter prices on eBay to benchmark your asking price before listing. PCGS or NGC holders significantly improve sale speed and final price. Completed listings are your best pricing guide.
Fast and convenient for common circulated examples where you want cash in hand. A coin dealer will typically offer 70–80% of silver melt for worn 1950 quarters. For varieties, most local dealers will either pass or discount heavily unless they specialize in Washington quarters — in that case, a quick ID visit is worth the trip before deciding where to sell.
A useful community for getting a second opinion on potential varieties. The r/coins community can help you determine whether your D-mint coin might be a D/S before you invest in PCGS/NGC grading fees. Not a direct sales venue, but invaluable for preliminary identification and connecting with knowledgeable collectors.
💡 Get it graded first if you have a variety. A raw (ungraded) 1950-D/S Over-Mint Mark often sells for significantly below its potential value because buyers can't authenticate the variety without expert confirmation. PCGS VarietyPlus and NGC VarietyPlus designations on the holder authenticate the variety and dramatically increase buyer confidence — and final sale price. For any coin you believe might be a D/S or S/D OMM, PCGS or NGC grading fees are almost always worth it.
