1964 Washington Quarter: The End of Silver Coinage
The 1964 Washington Quarter marks the final year of 90% silver composition for U.S. circulation quarters
The 1964 Washington Quarter represents a pivotal moment in American numismatic history as the final year 90% silver quarters were struck for circulation. Beginning in 1965, all quarters transitioned to copper-nickel clad composition, making 1964 the last opportunity to obtain silver quarters from circulation. This historic significance, combined with a controversial "date freeze" production policy, created one of the most interesting—and misunderstood—coins in U.S. numismatics.
Despite a combined mintage exceeding 1.26 billion coins across Philadelphia and Denver, the value of a 1964 quarter spans an extraordinary range. A worn circulated piece trades just above its $8.78 silver melt value, while the finest known MS-68 specimen sold for $38,400. Between these extremes lie fascinating die varieties, experimental Special Strike specimens worth five figures, and proof issues where surface designation matters more than numerical grade.
This comprehensive guide examines every aspect of 1964 quarter valuation: business strikes from both mints, proof issues with cameo designations, the ultra-rare SMS strikes, significant die varieties including the transitional Type C Reverse, and common mint errors. Whether you've inherited a roll of 1964 quarters or are considering a high-grade purchase, understanding the factors that drive value is essential to making informed decisions in this complex market.
How to Identify Your 1964 Washington Quarter
The D mint mark on Denver issues appears below the wreath on the reverse
All 1964 Washington Quarters share the same basic design elements. The obverse features John Flanagan's left-facing portrait of George Washington, with "LIBERTY" above, the date "1964" below, and the motto "IN GOD WE TRUST" to Washington's left. The reverse displays a heraldic eagle with wings spread, clutching arrows and an olive branch, with "UNITED STATES OF AMERICA" above, "QUARTER DOLLAR" below, and "E PLURIBUS UNUM" on a ribbon across the eagle.
Mint Mark Identification
The mint mark location is on the reverse, below the center of the wreath and above "QUARTER DOLLAR." Philadelphia-struck quarters bear no mint mark, while Denver issues display a small "D" in this position. All proof strikes were produced at Philadelphia and carry no mint mark. The mint mark is critical for identification, as certain varieties like the valuable Type C Reverse only occur on Denver strikes.
Strike Type Recognition
Distinguishing between business strikes, proofs, and the ultra-rare Special Mint Set (SMS) strikes requires attention to surface characteristics. Business strikes exhibit standard "cartwheel" luster with varying degrees of strike quality—many 1964 issues show weakness on Washington's hair details and the eagle's breast feathers due to rushed production. Proof strikes feature deep, mirror-like fields that contrast sharply with frosted devices, creating a "black-and-white" cameo effect, particularly on Cameo and Deep Cameo designated examples.
The experimental SMS strikes are neither typical business strikes nor proofs. They possess a unique "satin-like" finish with non-reflective fields, exceptionally sharp strikes showing full detail, and distinctive square, sharp rims. Only an estimated 20-50 SMS sets were produced, making these the true rarities of the 1964 issue. Due to their five-figure values, any coin suspected of being an SMS specimen should be authenticated by PCGS or NGC.
1964 Quarter Values: Complete Price Guide
The market for 1964 Washington Quarters exhibits extreme bifurcation. The vast majority of coins trade as bullion-plus pieces, valued just above their $8.78 silver content. However, specific combinations of grade, mint, strike type, variety, or designation can command premiums from hundreds to tens of thousands of dollars. Understanding these value drivers is essential for both collectors and those evaluating inherited coins.
1964 (Philadelphia) Business Strike
With a mintage of 560,390,585, the Philadelphia issue is common in all circulated grades and readily available in lower mint state grades. However, the rushed production resulted in generally poor strike quality and heavy bag marking. As David Hall noted in PCGS CoinFacts, this issue becomes "slightly rarer than the 1964-D" in true Gem condition. The value curve reflects this scarcity, with dramatic premiums emerging at MS-67 and above.

Source: NGC Price Guide (November 2025). The dramatic jump between MS-66 and MS-67 reflects the "MS-67 Wall" where population drops precipitously. PCGS reports only one MS-68 specimen.
💡 Auction Record
The auction record for a 1964 Philadelphia quarter is $7,188 for an MS-67 specimen sold in 2004. The single MS-68 coin certified by PCGS is valued at $6,700 by current price guides, suggesting it may command an even higher premium at auction.
1964-D (Denver) Business Strike
The Denver Mint struck a record 704,135,528 quarters in 1964, making this the highest mintage in the entire 1932-1964 Washington Quarter silver series. Like the Philadelphia issue, these coins were "made carelessly and in a hurry," creating the same challenge of locating true Gem examples. Despite the higher mintage, the Denver issue actually commands a slight premium over Philadelphia in the highest grades due to market dynamics and collector demand.

⚠️ Market Variance Alert
The >1,000% variance between the NGC guide price and the 2021 auction record for MS-68 specimens highlights the premium that "Top-Pop" (highest graded) coins command at major auctions. Registry set collectors competing for finest-known examples will pay substantial premiums beyond published guides.
1964 Proof (Philadelphia)
Proof designation dramatically affects value: Deep Cameo commands significant premiums
The U.S. Mint struck 3,950,762 proof quarters in 1964, representing a peak in hobby popularity. The rush to meet this demand resulted in a "slight dip in average quality" as dies were used past their prime, according to NGC analysis. However, the high mintage paradoxically made Cameo and Deep Cameo examples more available than in earlier years, though these still represent a small fraction of total production.
For 1964 proofs, the surface designation (Base, Cameo, or Deep Cameo) is far more important to value than the numerical grade. A perfect PF-70 base proof may retail for just $80, while a lower-grade PF-69 Deep Cameo has an auction record of $2,350. The market clearly prioritizes the dramatic "black-and-white" contrast of cameo designations over technical perfection in base proofs.
| Grade | Base Proof | Cameo (CAM) | Deep Cameo (DCAM) |
|---|---|---|---|
| PF-65 | $20 | $40 – $60 | $75 – $100 |
| PF-67 | $30 | $70 – $90 | $120 – $150 |
| PF-68 | $35 | $100 – $150 | $175 – $225 |
| PF-69 | $40 | $400 – $600 | $200 – $300 |
| PF-70 | $80 | $2,185 | No confirmed sales |
Source: NGC Price Guide and PCGS auction data (2020-2025). Note: The PF-69 DCAM market appears to have corrected significantly from its $2,350 peak record, with recent analysis suggesting current market values of $200-300.
1964 Special Strike (SMS) - Philadelphia
The 1964 Special Mint Set quarters represent the true rarities of the issue. With only an estimated 20-50 complete sets produced, these experimental strikes were prototypes for the 1965-1967 Special Mint Sets. Most known examples trace their provenance to the estate of former U.S. Mint Director Eva Adams, whose collection was sold by Stack's in the early 1990s.
These coins are distinguished by their unique "satin-like" non-reflective finish, exceptionally sharp strikes showing full detail, and distinctive square, sharp rims that differ from both business strikes and proofs. Due to their extreme rarity and five-figure values, authentication by PCGS or NGC is essential.

Grading 1964 Washington Quarters
Grade has dramatic impact on value, with MS-67+ specimens worth 100x more than circulated examples
Accurate grading is essential for determining a 1964 quarter's value, as the price difference between adjacent grades can be substantial, particularly at MS-66 and above. The rushed production conditions of 1964 created specific grading challenges: many coins exhibit weak strikes even in uncirculated condition, and heavy bag marking is common. Understanding these characteristics helps distinguish genuinely high-grade coins from pretenders.
Circulated Grades (G-4 through AU-58)
In Good-4 condition, the date is barely visible and Washington's portrait shows heavy wear with all hair detail completely smooth. Major design elements remain visible but flat. Very Fine-20 specimens show moderate wear with Washington's major hair strands visible but not sharp, and the eagle's wing feathers are clear but lack fine detail. About Uncirculated coins (AU-50 to AU-58) display only slight wear on the highest points—Washington's cheekbone and hair, and the eagle's breast—with most of the original mint luster remaining.
Wear first appears on Washington's hair and cheekbone, and the eagle's breast feathers
For circulated 1964 quarters, grade has minimal impact on value. All circulated examples from G-4 through VF-20 trade at the same $9.25 price point, just $0.47 above melt value. Only at AU-50 does a small premium emerge ($9.75), with AU-58 specimens reaching $11.25. Collectors seeking circulated examples should prioritize originality and problem-free surfaces over technical grade.
Mint State Grades (MS-60 through MS-70)
The mint state range is where value divergence becomes dramatic. MS-60 to MS-63 coins show no wear but may have significant bag marks, poor eye appeal, and weak strikes. MS-64 and MS-65 grades require better surfaces with fewer marks and acceptable strike quality, though the eagle's breast feathers may still show some weakness—a characteristic feature of 1964 production.
Strike quality varies widely on 1964 quarters; strong strikes command premiums in high grades
The "MS-67 Wall" separates common from rare. MS-66 specimens must have excellent strike quality with full breast feather details, minimal marks visible only under magnification, and strong eye appeal. MS-67 coins require near-perfect strikes, surfaces free of distracting marks, and exceptional overall quality. At this level, strike quality becomes paramount—even mark-free coins will not achieve MS-67 without a strong strike showing complete hair and feather detail.
MS-67+ and MS-68 grades represent condition rarities. Population reports show dramatic drop-offs at these levels, with only one PCGS MS-68 example known for the 1964-D. These grades command four to five-figure premiums because they combine exceptional strike quality, pristine surfaces, and outstanding eye appeal—characteristics rarely found together in the carelessly produced 1964 issues.
Proof Grades (PF-65 through PF-70)
Proof grading focuses on surface quality and preservation of the mirror finish. PF-65 specimens may show minor hairlines or contact marks visible under magnification. PF-67 coins display better surfaces with fewer distractions, while PF-68 examples show only the slightest imperfections under close inspection. PF-69 proofs are nearly perfect, with possibly one or two minute flaws, and PF-70 represents absolute perfection with no imperfections visible under 5x magnification.
However, for 1964 proofs, the designation (Base, Cameo, Deep Cameo) matters more than the numerical grade. A PF-69 Deep Cameo is worth more than a PF-70 base proof because collectors prioritize the dramatic frosted-device to mirrored-field contrast over technical perfection. When evaluating proofs, always consider designation before grade.
Valuable Die Varieties and Designations
The chaotic, multi-year production of 1964-dated quarters created numerous collectible die varieties. The U.S. Mint's practice of continuing to strike 1964-dated coins throughout 1965 and into early 1966 to combat a coin shortage resulted in indiscriminate die usage, creating significant transitional varieties. The Fivaz-Stanton (FS) numbering system is the standard reference for cataloging these varieties.
Philadelphia (P-Mint) Varieties
1964 DDO FS-101 (Doubled Die Obverse): This variety exhibits strong doubling on the obverse motto "IN GOD WE TRUST" and visible doubling on "LIBERTY." Circulated examples trade for $145-$250, while MS-65 specimens have sold at auction for approximately $228. High-grade MS-66 examples can retail for $299 or more.
1964 Type B Reverse FS-901: A major variety where a business strike was produced using a Proof reverse die. The diagnostics include sharper overall details, particularly on the leaves, and most importantly, clear separation between the letters "ES" in "STATES" and the leaf tip below them—a characteristic feature of the 1956-1964 Proof reverse hub. Circulated examples are valued around $26, MS-64 specimens trade for $35-$49, and MS-65+ examples can reach $110.
1964 DDR FS-801 (Doubled Die Reverse): Various doubled die reverse varieties exist in the 1964-P series, with FS-801 being the most prominent. Doubling is evident on "E PLURIBUS UNUM" and "QUARTER DOLLAR." MS-60+ specimens typically trade for $50-$70. Additional varieties (FS-802, FS-803, FS-804) are known but lack reliable public pricing data.
Denver (D-Mint) Varieties
The Type C Reverse shows diagnostic separation of the eagle's tail feather above the R in QUARTER
1964-D Type C Reverse FS-901 (Transitional Clad Reverse): This is the premier variety of the 1964 quarter series. A 90% silver planchet was struck with a reverse die intended for the 1965 copper-nickel clad quarters. The reverse shows "lowered and sharpened relief," and the primary diagnostic is the eagle's tail feathers: the tail feather above the "R" in "QUARTER" is sharp and clearly separated from the feather to its left, whereas on normal 1964 reverses these feathers are blurred together.
Raw AU/MS specimens typically trade for $140-$200. Certified MS-65 examples have sold at auction for approximately $271. The variety becomes extremely valuable in higher grades: an MS-66+ specimen realized (Stack's Bowers, June 2023)$8,400 at auction, establishing this as one of the most significant modern U.S. die varieties.
1964-D DDO FS-101 (Doubled Die Obverse): This Denver doubled die shows doubling on obverse elements, particularly the motto. AU-58 examples trade around $13, MS-64 specimens command $149-$190, and MS-65 examples are valued at $450-$500.
1964-D RPM FS-501, FS-502, FS-503 (Repunched Mint Mark): Multiple repunched mint mark varieties exist where the "D" was punched over another "D" at a slight rotation or offset. The FS-501 variety in AU-55 trades around $15, MS-63 examples command $154-$349, and uncirculated specimens typically retail for $49. One exceptional RPM variety (likely the more dramatic FS-502) reportedly sold for $10,000 in April 2022, though this represents an outlier for a particularly strong example.
1964-D DDR FS-801 (Doubled Die Reverse): Clear doubling appears on "UNITED STATES OF AMERICA" and "QUARTER DOLLAR." EF-40 specimens are valued around $45, AU-58 examples trade for approximately $98, and an MS-65 example realized (Great Collections, 2014) $385 at auction.
💎 Collector Tip
When hunting for varieties, focus first on the Type C Reverse (1964-D only) as it offers the best value-to-rarity ratio. The diagnostic tail feather separation is visible even to the naked eye on well-struck examples. Always verify suspected varieties through third-party certification—altered coins are common at the price points these varieties command.
Common Mint Errors and Their Values
Off-center strikes with visible dates command premiums based on displacement percentage
The 1964 Washington Quarter is found with various mint errors typical of high-volume production runs. While these errors are generally common across the series, the 90% silver content provides a floor value of $8.78 (current melt value) that supports error premiums. Error values are determined primarily by the severity and visual impact of the error, with dramatic examples commanding the strongest premiums.
Off-Center Strikes
Off-center strikes occur when the planchet is not properly centered in the collar during striking. Minor off-center strikes (5-10% displacement) with the date fully visible typically trade for $20-$35 in MS-63 condition. As displacement increases, so does value: 20-40% off-center pieces with visible dates command $75-$160 in AU/MS grades. Dramatic examples showing more than 50% off-center displacement with the date still visible can reach $100-$180 or more, depending on the aesthetic appeal of the strike.
Clipped Planchets
Clipped planchet errors result from the blanking press cutting overlapping planchets from the metal strip. A 10% curved clip (the most common type) on a 1964 quarter in AU/MS condition typically values at $25-$70. More dramatic clips affecting 20% of the planchet, particularly double clips, can reach $40-$100. Straight clips are generally more common and less valuable than curved clips of equivalent size.
Broadstrikes and Laminations
Broadstrikes occur when a coin is struck outside the collar, resulting in a larger-than-normal diameter and no reeded edge. These errors on 1964 quarters in AU/MS condition typically trade for $50-$150+, with value depending on how well-centered the strike is and overall eye appeal. Lamination errors, where the planchet's metal layers separate or flake, are also found on 1964 quarters and generally value in the $25-$100 range for AU/MS examples.
💡 Error Premium Note
While mint errors add premiums to 1964 quarters, these coins remain fundamentally common error carriers due to the enormous mintages. The silver content ensures error examples won't trade below melt value, but spectacular five-figure error prices seen on some modern issues are unlikely for 1964 quarters unless the error is extraordinarily dramatic and well-preserved.
Authentication and Problem Identification
The substantial value differences between varieties, grades, and strike types create strong incentives for alteration and counterfeiting of 1964 Washington Quarters. Understanding common authenticity issues and problem coin characteristics is essential for avoiding costly mistakes, particularly when considering high-grade or variety purchases.
Added mint marks represent a common alteration. A "D" can be added to a common Philadelphia quarter to create a fraudulent Type C Reverse variety, potentially increasing value from under $10 to several hundred dollars. These added mint marks often show differences in depth, style, or position compared to genuine Denver strikes. Under magnification, tooling marks or surface disturbances around the added mint mark become visible. For any variety dependent on mint mark attribution—particularly the valuable Type C Reverse—third-party certification is essential.
Altered reverses present another authentication challenge. The diagnostic tail feather differences that distinguish the Type C Reverse from normal reverses can be mimicked through careful tooling or re-engraving. Fraudulent examples may show file marks, unnatural metal flow, or microscopic disturbances in the fields around the altered area. Genuine Type C Reverses exhibit consistent strike characteristics throughout the coin—altered examples often show inconsistencies between the modified area and the rest of the coin's surfaces.
The ultra-rare SMS strikes face a different authentication challenge: faked finishes. Business strikes may be polished to create a false "satin" appearance, while proof coins can be chemically stripped or "hazed" to remove their mirror finish. Genuine SMS strikes show a consistent, natural satin finish across the entire surface with square, sharp rims and exceptional strike quality throughout. Any coin purported to be an SMS specimen must be certified by PCGS or NGC—the five-figure values involved demand professional authentication.
Problem coins represent the most common value trap. "Details" grades indicate coins that have been cleaned, polished, scratched, damaged, or otherwise altered, voiding their numismatic premium. Common problems include cleaning, which creates unnaturally bright surfaces covered in microscopic hairlines from abrasive wiping; polishing, which produces a "dead," non-reflective luster with residue buildup around letters and devices; and "whizzing," where coins are buffed with high-speed tools to create false luster with a greasy appearance.
Environmental damage is also common on silver coins. PVC contamination from improper storage in soft plastic flips creates green, oily residue that permanently damages surfaces. Toning, if natural, can be acceptable or even desirable, but artificial toning applied to mask cleaning or improve appearance significantly reduces value. Any coin showing problem characteristics should be assumed to be worth only melt value plus a minimal premium, regardless of its technical grade.
Proper Storage and Preservation
The 1964 Washington Quarter's 90% silver composition makes proper storage and handling essential for preserving both numismatic and silver value. Silver is a relatively soft, reactive metal that tarnishes when exposed to sulfur compounds in the air, and improper storage can cause permanent damage that eliminates collector premiums.
Always handle coins by their reeded edges only. Fingerprints contain oils, salts, and acids that etch into silver surfaces, creating permanent marks. Even brief contact with the coin's face can cause problems—a single fingerprint left on a high-grade uncirculated coin can reduce its value from hundreds to the melt value floor of $8.78. When examining coins, hold them over a soft surface and use proper lighting at an angle to avoid breathing directly on the coin's surfaces.
Storage containers must be archival quality and chemically inert. Suitable options include Mylar flips (not vinyl), rigid plastic holders (Airtite capsules), or NGC/PCGS certified holders. Never use soft, flexible polyvinyl chloride (PVC) flips—these leach plasticizers onto coin surfaces, creating green, oily deposits that permanently damage silver. If you've inherited coins in soft vinyl flips, remove them immediately and transfer to Mylar or hard plastic holders.
Store coins in a stable environment away from temperature and humidity extremes. Basements are generally unsuitable due to dampness. Climate-controlled interior spaces work best. Avoid storing coins near rubber bands, which release sulfur compounds that accelerate toning. While some natural toning can be attractive and acceptable to collectors, rapid or uneven toning often indicates environmental problems that should be corrected.
Never attempt to clean coins, even if they appear dirty or tarnished. Cleaning voids numismatic value by creating hairlines, removing original surfaces, and eliminating the natural patina that develops over time. A naturally toned, original coin is always more valuable than a cleaned example, even if the cleaned coin appears "nicer" to untrained eyes. If a coin has numismatic value beyond melt, preservation of its original surfaces is paramount—cleaning reduces it to bullion value regardless of technical grade.
Frequently Asked Questions
How much is my 1964 Washington Quarter worth?
The value depends on mint mark, grade, strike type, and whether it's a variety. Common circulated examples (G-4 through VF-20) are worth $9.25, just above the $8.78 silver melt value. Uncirculated business strikes range from $13.75 (MS-60) to $38,400 (MS-68 record). Proof examples trade for $20-$2,350 depending on grade and cameo designation. The ultra-rare SMS strikes command $1,250-$35,000. Significant varieties like the 1964-D Type C Reverse in high grade can reach $8,400.
How do I identify the mint mark on my 1964 quarter?
Look on the reverse (eagle side) below the center of the wreath and above the words "QUARTER DOLLAR." If you see a small "D," your coin was struck at the Denver Mint. If there's no mint mark in this location, your coin was struck at Philadelphia. All proof coins were also struck at Philadelphia with no mint mark. The mint mark is small but should be clearly visible to the naked eye on unworn coins.
What makes some 1964 quarters worth thousands of dollars?
High values result from extreme grade rarity (MS-67 and above), strike type (SMS specimens), significant die varieties (Type C Reverse), or proof designation (Deep Cameo). The massive 1.26 billion mintage was produced carelessly and in a hurry, making true Gem examples extraordinarily rare. The experimental SMS strikes had only 20-50 sets produced. The Type C Reverse is a major transitional variety where a silver planchet received a reverse die intended for 1965 clad coins.
Should I get my 1964 quarter professionally graded?
Grading is worthwhile if your coin appears to be MS-66 or better (no wear, minimal marks, strong strike), is a suspected SMS strike, or shows characteristics of a significant variety like the Type C Reverse. Grading costs $20-$50+ per coin, so it only makes economic sense if the coin's potential value significantly exceeds this cost plus the current $9.25 common value. Circulated coins and typical uncirculated examples aren't worth the grading expense.
How can I tell if my 1964 quarter has been cleaned?
Cleaned silver coins show several telltale signs: unnaturally bright, "shiny" surfaces; fine hairlines or microscopic scratches covering the surface (visible under magnification); "dead" luster that lacks the natural cartwheel effect; residue buildup around letters and design elements; or uneven coloration with areas of different brightness. Cleaned coins lose their numismatic premium and are worth only melt value regardless of technical grade. If in doubt, compare your coin to certified examples or consult a professional dealer.
What's the difference between a 1964 proof and a business strike?
Business strikes were made for circulation and exhibit standard "cartwheel" mint luster. Proofs were specially made for collectors using polished dies and planchets, resulting in mirror-like fields that contrast with frosted devices. Proofs show sharper details and were struck multiple times. The 1964 SMS (Special Mint Set) strikes are neither—they have a unique "satin" finish, non-reflective fields, and exceptionally sharp strikes with square rims. SMS coins are extremely rare (20-50 sets) and valuable.
Why did the U.S. stop making silver quarters after 1964?
Rising silver prices made it economically unfeasible to continue striking 90% silver coins for circulation. By 1965, the silver content in quarters exceeded their face value. The Coinage Act of 1965 mandated the transition to copper-nickel clad composition to preserve silver for other uses and prevent coins from being hoarded or melted. The "date freeze" policy allowed mints to continue striking 1964-dated coins into 1966 to meet demand while tooling was prepared for the new clad coins.
How do I safely store my silver 1964 quarters?
Use only archival-quality, inert holders such as Mylar flips (not vinyl), Airtite capsules, or certified holders from NGC/PCGS. Never use soft PVC flips which leach damaging chemicals onto silver. Store in a stable, climate-controlled environment away from humidity, temperature extremes, and sulfur-containing materials (like rubber bands). Always handle coins by their edges only—fingerprints permanently damage silver surfaces. Never clean coins as this destroys numismatic value.
Are 1964 quarters with errors valuable?
Common errors on 1964 quarters include off-center strikes, clipped planchets, broadstrikes, and laminations. These carry modest premiums based on error severity: $20-$35 for minor off-center strikes, $75-$180 for dramatic off-center examples, and $25-$150 for other common errors. The silver content provides an $8.78 floor value. However, 1964 quarters are common error carriers due to enormous mintages, so values remain relatively modest unless the error is exceptionally dramatic and the coin is well-preserved.
What's the value difference between Cameo and Deep Cameo proofs?
Designation dramatically affects proof values. At PF-69, a base proof trades for $40, a Cameo for $400-$600, and a Deep Cameo for $200-$300. The market prioritizes the "black-and-white" contrast of cameo designations over numerical grade—a PF-70 base proof ($80) is worth less than a lower-grade PF-69 Cameo. Deep Cameo proofs show the strongest frosted-device to mirrored-field contrast and historically commanded the highest premiums, though market dynamics have shifted somewhat in recent years.
