The Valuable 1971 Quarter Errors (Complete Guide)

The 1971 Washington quarter has produced several significant error varieties that command strong premiums above regular coin values. Two of the most important β€” the Philadelphia and Denver Doubled Die Reverse FS-801 β€” are attributed varieties with CONECA and Fivaz-Stanton numbers. The error coins below are ranked by overall collector demand, value potential, and frequency of appearance on the market.

1971-P quarter reverse showing DDR FS-801 doubled die lettering with doubled letters visible in UNITED STATES OF AMERICA
Most Famous $100 – $8,813+

1971-P Doubled Die Reverse β€” FS-801 (027.7)

The 1971-P DDR FS-801 is produced when the working die used to strike Philadelphia quarters received two slightly misaligned hub impressions during the die-making process. Because the die itself carries the doubled image, every coin struck from that die shows the same doubling β€” making it a true doubled die rather than a mechanical doubling or die polish mark.

The most diagnostic feature is strong doubling on the reverse lettering "UNITED STATES OF AMERICA" and "QUARTER DOLLAR." Under a 5Γ— to 10Γ— loupe, the letters appear to have a second impression offset to one side, creating what specialists call "split serifs" β€” the fine strokes at the ends of each letter visibly separate. The doubling is sometimes detectable with the naked eye under proper raking light.

A PCGS MS-65 example of this variety sold for $8,813 at Heritage Auctions in February 2017 β€” the record auction result for any 1971 quarter. Even in circulated grades, the FS-801 commands strong premiums: an AU-55 example has sold above $600, and VF-20 examples have traded for over $200. The Fivaz-Stanton designation FS-025Β’-027.7 confirms its status as a recognized major variety.

How to spot it

Examine the reverse lettering "UNITED STATES OF AMERICA" and "QUARTER DOLLAR" under a 10Γ— loupe. Look for clearly doubled letters showing split serifs β€” each character appears to have a shadow or second outline offset in one direction. Mechanical doubling is flat; FS-801 doubling has rounded, raised edges on both impressions.

Mint mark

Philadelphia β€” no mint mark on obverse. This specific FS-801 designation (027.7) applies exclusively to the Philadelphia issue.

Notable

Designated FS-025Β’-027.7 by CONECA/Fivaz-Stanton. PCGS #5901. Heritage Auctions recorded the top sale of $8,813 for a PCGS MS-65 example in February 2017. GreatCollections has recorded five confirmed auction sales ranging from $31 (VF-20) to $619 (XF-45).

1971-D quarter reverse showing DDR FS-801 Denver variety with doubled reverse lettering visible under magnification
Rarest $100 – $1,280+

1971-D Doubled Die Reverse β€” FS-801 (027.8)

The 1971-D DDR FS-801 is significantly rarer than its Philadelphia counterpart β€” PriceCharting records show it sells roughly once per year on the open market, and population reports indicate only a handful of certified examples exist. Like the Philadelphia variety, the error originates at the die-hubbing stage: the die received two misaligned hub strikes, embedding a doubled image into every coin struck from that die.

The doubling on the Denver variety is visible on the same diagnostic areas β€” "UNITED STATES OF AMERICA" and "QUARTER DOLLAR" on the reverse β€” and exhibits the same split-serif character. Specialists note that the doubling on the 027.8 die may show a slightly different rotation offset than the 027.7 Philadelphia version, so attribution is important for accurate valuation. The presence of the small "D" mint mark on the obverse confirms Denver origin.

This variety's rarity translates directly to auction premiums. A PCGS XF-40 example achieved $1,280 in an eBay sale recorded by PCGS CoinFacts in January 2023 β€” more than any circulated example of the Philadelphia DDR has realized in recent years. An EF-40 example also sold for $1,280 via eBay, which Heritage Auctions has confirmed as the auction record for this variety. With only a handful of certified examples and infrequent appearances, the 1971-D DDR FS-801 (027.8) is considered the top rarity in the 1971 series.

How to spot it

Confirm the "D" mint mark on the obverse near Washington's hair ribbon, then examine the reverse lettering under a 10Γ— loupe. Look for the same split-serif doubling on "UNITED STATES OF AMERICA." Attribution against both 027.7 and 027.8 diagnostics is recommended before submission for grading.

Mint mark

Denver β€” small "D" on obverse. FS designation 027.8 applies exclusively to Denver-minted 1971 quarters.

Notable

Designated FS-025Β’-027.8 by CONECA/Fivaz-Stanton. PCGS #146086. Auction record: $1,280 for an XF-40 example, January 2023 (PCGS CoinFacts verified). PriceCharting lists population as extremely low β€” "Only Pop 4" noted on a recent eBay listing.

1971 Washington quarter with dramatic off-center strike showing shifted design and blank crescent area with full date still visible
Most Dramatic $25 – $500+

1971 Off-Center Strike Error

An off-center strike occurs when the blank planchet is not properly positioned in the coining press before the dies come together. The result is a coin where the design is shifted off to one side, leaving a blank, unstruck crescent area at the opposite edge. This error can occur at any stage of feeding and is known on both Philadelphia and Denver 1971 quarters.

Value depends almost entirely on two factors: how far off-center the strike is (expressed as a percentage) and whether the full date β€” "1971" β€” remains clearly visible. A coin that is only 5–10% off-center and shows a complete date may bring $25–$60. At 40–50% off-center with a visible date, collector interest rises sharply and realized prices of $150–$500 or more are well-documented. A 65% off-center Denver example reportedly sold for $3,290 at Heritage Auctions in 2010, according to multiple sources.

These errors are visually compelling and accessible to general collectors, which keeps demand steady. The blank area should appear raw and unstruck, showing the planchet's copper-nickel surface without design elements. Any coin with edge reeding still partially intact and a dramatic off-center shift is especially appealing to error specialists.

How to spot it

Look for a blank, featureless crescent along one edge with the design visibly shifted toward the opposite rim. Check that the date "1971" is fully readable β€” this is critical for value. Measure the percentage of blank area vs. design area to estimate off-center severity.

Mint mark

Both Philadelphia (no mark) and Denver (D) issues are known. San Francisco proof strikes can also show this error.

Notable

A 1971-D example struck approximately 65% off-center reportedly sold for $3,290 at Heritage Auctions in 2010 per multiple sources, though professional authentication is required to confirm specific dramatic strikes. Minor off-centers (5–10%) are far more common and bring $25–$60.

1971 Washington quarter broadstrike error showing wider diameter, smooth non-reeded edge, and design elements spread toward rim
Best Kept Secret $25 – $150

1971 Broadstrike Error

A broadstrike happens when a planchet is fed into the press but the retaining collar β€” the steel ring that holds the blank in place and forms the reeded edge β€” fails to engage properly. Without the collar constraining the metal, it spreads outward in all directions when struck, producing a coin that is noticeably wider and thinner than a standard quarter.

The most reliable visual diagnostics are the edge and the diameter. A standard 1971 quarter has a reeded edge and measures exactly 24.3 mm across. A broadstrike will have a smooth, non-reeded edge and will measure wider β€” often 25–27 mm or more depending on severity. The design elements on high-relief areas like Washington's portrait tend to spread and flatten toward the rim. This error is noted as somewhat more common on Philadelphia issues, where striking quality was generally lower than at Denver in 1971.

While broadstrikes are among the more common dramatic errors on clad quarters, coin collectors continue to pay premiums for visually clean, well-defined examples. Certified broadstrike quarters in mint state condition with full, sharp designs despite the error bring the strongest premiums, typically in the $75–$150 range. A standard circulated broadstrike trades for $25–$50.

How to spot it

Run a finger along the edge β€” a broadstrike will feel smooth with no reeding. Then measure the diameter with calipers: any coin exceeding 24.3 mm with a smooth edge is a strong broadstrike candidate. Also check thickness, which will be less than a standard quarter's 1.75 mm.

Mint mark

Both Philadelphia (no mark) and Denver (D) issues known; more frequently reported on Philadelphia 1971 quarters due to lower strike quality.

Notable

Per multiple sources, a typical circulated broadstrike quarter trades for approximately $25–$50. Mint state certified examples with strong visual appeal bring $75–$150. Verification of edge and diameter is essential to distinguish broadstrikes from coins with heavy rim wear.

1971 Washington quarter struck on wrong planchet showing smaller diameter and truncated design elements compared to a standard quarter
Condition Rarity $500 – $3,500+

1971 Wrong Planchet / Off-Metal Error

A wrong planchet error occurs when a blank intended for a different denomination β€” most commonly a cent, nickel, or dime β€” is accidentally fed into the quarter press. The Washington quarter design is then stamped onto a planchet of the wrong size, weight, and metal composition. These errors are extremely rare because modern Mint press feeding systems are designed to reject the wrong-sized blanks, yet documented examples do exist for 1971 quarters.

The most striking identification feature is weight and size divergence. A standard 1971 quarter weighs exactly 5.67 grams and measures 24.3 mm. A quarter struck on a cent planchet weighs approximately 2.5–3.1 grams and is noticeably smaller in diameter, with design elements cut off at the edges. A Heritage Auctions-recorded sale documented a 1971-D quarter struck on a cent planchet (NGC MS-64) that realized $1,527.50. A documented quarter struck on a dime planchet (2.27 grams, Choice AU) was listed at $495.

The extreme rarity of verified wrong planchet 1971 quarters makes them the highest-value single error in this series outside of the DDR varieties. Professional authentication by PCGS or NGC is mandatory for any suspected wrong planchet coin β€” the certification cost is easily justified given that genuine examples trade from $500 into the thousands.

How to spot it

Weigh the coin on a precise digital scale. Any weight significantly below 5.67 grams demands further examination. Check the edge β€” a quarter on a cent planchet will lack the copper-core stripe visible on clad coins. Color and diameter will also deviate noticeably from standard.

Mint mark

Both Philadelphia and Denver issues documented; one confirmed example is a 1971-D struck on a cent planchet, certified NGC MS-64 (Heritage Auctions lot #8977).

Notable

Heritage Auctions lot #8977 confirmed a 1971-D struck on a cent planchet at NGC MS-64 for $1,527.50. A quarter on dime planchet (2.27 g, Choice AU) was offered at $495 by Yesterday's Change. Professional authentication is required before any sale.

1971-S proof Washington quarter in Deep Cameo condition showing frosted devices against mirror-like fields
Most Valuable Proof $50 – $7,475

1971-S Deep Cameo Proof (DCAM)

The 1971-S Deep Cameo proof is not an error coin but rather the premium grade designation within the San Francisco proof set. Proof coins are specially struck multiple times on polished planchets using highly polished dies to produce mirror-like fields. The most desirable examples β€” designated "Deep Cameo" by PCGS (or "Ultra Cameo" by NGC) β€” exhibit strongly frosted, white-appearing design elements that contrast dramatically against the mirror fields.

The key diagnostic is the quality and depth of the frost on the devices: Washington's portrait and the eagle should appear blazing white and sharply defined, while the fields should be perfectly reflective. Low-end DCAM examples that barely qualify may show thin or uneven frost. The "monster" DCAM examples β€” with unbroken, heavy frost throughout β€” are the coins that command four-figure prices. Standard PR-69 examples without the DCAM designation trade for only $15–$28.

The top auction result for a 1971-S DCAM is $7,475 for a PCGS PR-69 DCAM, realized at Heritage Auctions in November 2007. This explains the extreme value range within the DCAM designation: quality variation within any single grade tier is enormous, and the best examples are genuinely scarce. With a total proof mintage of 3,220,733, standard proofs are common, but pristine DCAM examples in PR-69 with exceptional frost are true rarities.

How to spot it

Under careful lighting, tilt the coin to reveal whether the fields are mirror-bright (reflecting like a miniature mirror). The devices β€” Washington's hair, eagle's feathers β€” should appear stark white and heavily frosted. Weak frost that looks gray or transparent will not qualify as Deep Cameo.

Mint mark

San Francisco only β€” small "S" on obverse. All 1971-S proof quarters carry this mark; the DCAM designation is based on strike quality, not origin.

Notable

Auction record: $7,475 for PCGS PR-69 DCAM at Heritage Auctions, November 2007. NGC population data shows PR-69 DCAM as the most heavily graded tier with 21 examples, while PR-70 examples are unrecorded at NGC. PCGS notes a PR-70 sale at $4,000.

Composition Note: All 1971 quarters are copper-nickel clad copper (not silver). The outer layers are 75% copper and 25% nickel, bonded to a pure copper core. Total weight: 5.67 grams. Diameter: 24.3 mm. Edge: reeded. Designer: John Flanagan. The copper core is visible as an orange stripe on the coin's edge. Metal value is approximately $0.06 β€” well below face value.

How to Grade Your 1971 Quarter

Grading strip showing four 1971 Washington quarters from worn Good grade through gem uncirculated MS-66 illustrating all condition tiers
G–VF (Worn)

Worn / Circulated

Washington's hair above the ear shows heavy flattening with little or no individual strand detail. The "IN GOD WE TRUST" motto is readable but worn. On the reverse, the eagle's breast feathers show significant flattening. Rim may show dings. Value: $0.25–$1.00 for standard coins.

Fine–XF (Light Wear)

Fine / Very Fine

Washington's major hair features remain, but fine strands in the high-relief curl above the ear begin to merge. Cheekbones may show slight friction. Reverse eagle feathers are defined but not sharp. All legends crisp. Still in the face value tier for most 1971 quarters unless error or variety present.

MS-60–65 (Uncirculated)

Uncirculated

No wear on any surface, but bag marks and contact marks from handling are normal. Look for original Mint luster β€” a cartwheel-like shimmer when the coin is tilted. The 1971-P is notorious for weak luster and heavy bag marks even in mint sets. Strong eye appeal is critical; many MS-63 coins lack it. Value: $2–$15.

MS-66+ (Gem)

Gem Uncirculated

MS-66 requires near-perfect surfaces with only minor contact marks not in focal areas, strong luster, and above-average strike. The jump to MS-67 is dramatic β€” PCGS notes the 1971-P is among the three toughest clad dates for this grade. MS-67 examples number in the single digits for Philadelphia. Value: $70–$8,812.

Pro Tip β€” Luster and Strike Quality: The 1971-P Philadelphia quarter is recognized for consistently weak strikes and poor luster even in mint sets β€” this is a documented characteristic, not a sign of post-mint damage. When evaluating a 1971-P, prioritize coins with unusually strong luster and minimal contact marks. A 1971-P quarter that genuinely grades MS-66 or above is a coin that beat the odds from the Mint floor forward. For proof coins (1971-S), look specifically for "Deep Cameo" (PCGS) or "Ultra Cameo" (NGC) designation, which requires strong, unbroken frost on all devices β€” this designation alone can multiply a coin's value tenfold.

Where to Sell Your Valuable 1971 Quarter

The best venue depends on your coin's value tier. A circulated example is fine at a local shop; a DDR FS-801 in gem condition should go to auction.

πŸ›οΈ Heritage Auctions

Best for high-value examples: gem uncirculated MS-66+ business strikes, DCAM proofs, or confirmed DDR FS-801 varieties. Heritage reaches the most serious buyers for 1971 Washington quarters and has established the key auction records for this series ($8,812, $4,560, $7,475). Minimum consignment thresholds apply β€” contact their consignment team early.

πŸ›’ eBay

Excellent for mid-range coins: broadstrikes, off-center errors, uncirculated business strikes in MS-63 to MS-65, and circulated DDR examples. Check recently sold prices for 1971 Washington quarters on eBay to see realistic current comps before setting your price. Use "sold listings" in eBay's advanced search to filter to completed sales only β€” active listings are not market prices.

πŸͺ Local Coin Shop

Ideal for quick sales of circulated or low-uncirculated 1971 quarters without the hassle of shipping and fees. Dealers typically offer 50–60% of retail for common grades. Bring your coin in raw (ungraded) if it's only worth face value to $5; for anything showing signs of DDR doubling or significant errors, get a professional appraisal first or submit for third-party grading before any sale.

πŸ’¬ Reddit r/Coins4Sale

Good peer-to-peer option for error coins with clear photos and honest descriptions. The community appreciates detailed documentation: include multiple high-resolution photos, weight measurements for error coins, and any relevant third-party grading information. Verified sellers with established feedback history get the strongest prices. Fees are lower than eBay but buyer protections are minimal.

πŸ’‘ Get It Graded First (When It Matters)

If your 1971 quarter appears to be MS-66 or higher, shows visible DDR doubling on the reverse, has a dramatic mint error, or is a 1971-S proof that may qualify as Deep Cameo, professional grading by PCGS or NGC is strongly recommended before sale. The cost (typically $20–$50 for standard service) is easily justified: the difference between MS-65 ($10–$15) and MS-67 ($1,250–$1,900) represents a return of many multiples on the grading fee. For error coins, authentication also protects buyers and commands significantly higher realized prices.

Frequently Asked Questions

How much is a 1971 quarter worth?

Most circulated 1971 quarters (Philadelphia and Denver) are worth their face value of $0.25. Uncirculated examples typically bring $1–$15 depending on grade. The range widens dramatically at higher grades: an MS-67+ example sold for $8,812 at Heritage Auctions. The 1971-S proof in Deep Cameo can reach $7,475. Error coins and doubled die varieties carry separate, often much higher premiums.

Is the 1971 quarter made of silver?

No. The 1971 quarter is copper-nickel clad, not silver. U.S. quarters transitioned from 90% silver to clad composition in 1965. The 1971 quarter has an outer layer of 75% copper and 25% nickel bonded to a pure copper core. Its metal content is worth only a few cents β€” well below face value. There are no silver 1971 quarters in circulation.

What is the 1971 quarter DDR FS-801 error?

The DDR FS-801 (Fivaz-Stanton number 027.7 for Philadelphia, 027.8 for Denver) is a doubled die reverse error. During the hubbing process, the working die received two slightly offset impressions, leaving doubled outlines on the reverse. The doubling is visible β€” often with the naked eye β€” on the lettering "UNITED STATES OF AMERICA" and "QUARTER DOLLAR." A Philadelphia example graded MS-65 sold for $8,813 at Heritage Auctions.

What does the 1971 quarter mint mark look like and where is it?

The mint mark on a 1971 quarter is on the obverse (heads side), located just to the right of Washington's hair ribbon, near the bottom of his portrait. Denver coins show a small "D." San Francisco proof coins show a small "S." Philadelphia coins from 1971 have no mint mark β€” the absence of a letter is normal for Philadelphia issues of this era and does not indicate an error.

How many 1971 quarters were made?

The U.S. Mint struck 109,284,000 quarters at Philadelphia (no mint mark), 258,634,428 at Denver (D), and 3,220,733 proof quarters at San Francisco (S) in 1971. Total production exceeded 371 million coins. Despite the large Philadelphia mintage, high-grade MS-67 examples are considered among the three toughest dates in the entire clad Washington quarter series to find.

What makes a 1971 quarter valuable?

Four factors drive 1971 quarter value: (1) Condition β€” MS-67 and above are extreme condition rarities worth thousands; (2) Error varieties β€” the DDR FS-801 doubled die reverse adds substantial premiums even in circulated grades; (3) Strike type β€” the 1971-S Deep Cameo proof commands premiums for strong frosted contrast; (4) Dramatic mint errors like off-center strikes, wrong planchet, and broadstrikes can be worth $25 to several thousand dollars.

What is the most valuable 1971 quarter ever sold?

The highest confirmed sale for a 1971 Washington quarter is $8,812.50 for a PCGS MS-67+ example from the Philadelphia Mint, sold at Heritage Auctions. The 1971-D holds the Denver record at $4,560 for an MS-68 example sold at Heritage in June 2019. For proof coins, a 1971-S graded PR-69 Deep Cameo sold for $7,475 at Heritage Auctions in 2007.

Is a 1971 quarter without a mint mark rare?

No. A 1971 quarter without a mint mark is a normal Philadelphia Mint coin β€” Philadelphia did not use mint marks on business strikes during this era. Over 109 million were produced. The absence of a mint mark is not an error. However, extremely high-grade Philadelphia examples (MS-67 and above) are genuine rarities, with fewer examples known than many collectors expect given the large mintage.

How do I tell if my 1971 quarter has the doubled die reverse (DDR)?

Flip the coin to the reverse (eagle side) and examine the lettering "UNITED STATES OF AMERICA" and "QUARTER DOLLAR." On a genuine DDR FS-801, you will see clearly doubled letters β€” each character appears to have a shadow or second impression slightly offset from the first. The split serifs are often visible to the naked eye under good lighting, and strongly confirmed with a 5Γ— to 10Γ— loupe. Normal quarters show clean, single-impression letters.

Should I clean my 1971 quarter before selling?

Never clean a 1971 quarter before selling. Cleaning permanently removes the coin's original surface luster and microscopic details that graders look for. A cleaned coin will be designated "details" or "cleaned" by PCGS or NGC, which dramatically reduces its market value. Even a lightly cleaned MS-65 coin can drop to a fraction of its original value. Leave coins exactly as found and let a professional grader assess them.
