1870 Shield Nickel: America's First Base-Metal Five-Cent Piece

The 1870 Shield Nickel's Type 2 design features no rays between the reverse stars

The 1870 Shield Nickel represents a pivotal moment in United States coinage history as part of the nation's first copper-nickel five-cent series. Struck exclusively at the Philadelphia Mint with a mintage of 4,806,000 business strikes and an estimated 1,000 Proofs, this coin exhibits the Type 2 "Without Rays" design—a mid-series modification made in 1867 to address die failure problems caused by the series' notoriously hard copper-nickel alloy.

Values range from $25 to $30 for heavily circulated examples in Good condition, escalating to $1,500 to $2,400 for Gem Mint State specimens graded MS-65, with a remarkable $10,281 auction record for an MS-66. The coin's intrinsic metal value is negligible at approximately six cents, making numismatic factors—condition rarity, strike quality, and die varieties—the sole drivers of collector demand.

This comprehensive guide examines the 1870 Shield Nickel's identification features, current market valuations across all grades, eight documented die varieties including the famous FS-301 Indian Cent die clash, common mint errors, authentication considerations, and proper preservation techniques. Whether you're a beginning collector or seasoned numismatist, understanding the 1870's unique characteristics and grading challenges is essential for accurate valuation.

How to Identify the 1870 Shield Nickel

The absence of rays between stars is the definitive Type 2 diagnostic

All 1870 Shield Nickels are Type 2 "Without Rays" examples, distinguishing them from the earlier 1866-1867 Type 1 coins that featured prominent rays emanating between the reverse stars. This design change was implemented mid-way through 1867 to improve die longevity, as the intricate ray details combined with the extreme hardness of the 75% copper, 25% nickel alloy caused excessive die wear and frequent failures.

Design Features

Obverse: Chief Engraver James B. Longacre's design features a shield derived from the Great Seal of the United States, displaying 13 vertical stripes (paleways) and a horizontal top bar (chief). The motto "IN GOD WE TRUST" appears in an arc above the shield, while the date "1870" is positioned below. The shield's intricate details—particularly the individual vertical lines—are critical diagnostic points for assessing strike quality and wear.

Reverse: A large numeral "5" dominates the center, encircled by thirteen stars representing the original colonies. The legend "UNITED STATES OF AMERICA" frames the upper two-thirds of the design. The key diagnostic feature is the complete absence of rays in the spaces between the stars—if any ray-like elements appear, the coin is a Type 1 from 1866-1867, not an 1870.

Mint Marks and Origin

All 1870 Shield Nickels were produced at the Philadelphia Mint. During this period in U.S. Mint history, coins struck at the main Philadelphia facility did not carry a mint mark. Therefore, all genuine 1870 Shield Nickels will have no mint mark. Any example bearing a mintmark (D, S, CC, O, etc.) is either a later date or a counterfeit.

Business Strike vs. Proof Identification

Proof strikes show mirrored fields and sharp square rims distinct from business strikes

Distinguishing between a business strike (intended for circulation) and a Proof (specially made for collectors) is critical, as values differ substantially:

Business Strikes: Exhibit satin-like or slightly grainy luster. Often show some degree of striking weakness, particularly on the shield's vertical lines, the leaves above the shield, and the centers of reverse stars. Early die state examples may display semi-reflective "Prooflike" (PL) fields, but these lack the deep, liquid mirrors of true Proofs. Rims are typically rounded and flow gently into the fields.

Proof Strikes: Feature deeply mirrored, highly polished fields created through specialized planchet and die preparation. Struck multiple times at high pressure, resulting in exceptionally sharp details on all design elements. The raised devices often display a frosted appearance, creating "Cameo" (CAM) or "Deep Cameo" (DCAM) contrast. Most definitively, Proof strikes exhibit sharp, squared-off rims forming a distinct 90-degree angle with the edge—often called a "wire rim"—which is one of the most reliable indicators of authentic Proof manufacture.

1870 Shield Nickel Values by Grade and Strike Type

Value escalates dramatically from circulated to Gem Mint State grades

The 1870 Shield Nickel's market is distinctly divided between business strikes produced for circulation and special Proof strikes created for collectors. Within each category, values escalate sharply with condition, and for Mint State examples, strike quality becomes a critical value determinant beyond the numerical grade.

1870 Business Strike (Philadelphia Mint)

With 4,806,000 pieces struck, the business strike 1870 is readily available in circulated grades but becomes progressively scarce in Mint State. PCGS estimates only 75 examples survive at MS-65 or better, making Gem specimens genuinely rare. The copper-nickel alloy's extreme hardness resulted in many weakly struck coins, so fully detailed examples with vibrant luster command strong premiums within each grade level.

Auction Highlights: A PCGS MS-65 realized $2,400 (Stack's Bowers, August 2023), demonstrating strong demand for Gem examples. The MS-66 record of $10,281 was set by a PCGS-graded specimen at Legend Auctions in March 2020, while another MS-66 sold for $4,900, illustrating how eye appeal and strike quality create significant variance even within the same numerical grade.

1870 Proof Strike (Philadelphia Mint)

The Philadelphia Mint struck an estimated 1,000 Proof Shield Nickels in 1870 for sale to collectors. These coins were produced with specially prepared, highly polished dies and planchets, resulting in deeply mirrored fields and sharp details. Proofs with strong "Cameo" or "Deep Cameo" contrast—where frosted devices stand out against liquid-mirror fields—command significant premiums.

Cameo Designation Premium: The June 2022 auction result of $1,080 for a PR-65 CAM versus guide values of $700-$1,000 for brilliant PR-65 specimens demonstrates the 30-50% premium collectors pay for strong Cameo contrast. Deep Cameo (DCAM) examples, though not represented in available auction data for 1870, typically command even higher premiums when encountered.

Grading the 1870 Shield Nickel: Key Diagnostics

These high points show wear first—examine carefully to determine grade

Grading Shield Nickels presents unique challenges due to the series' notorious striking problems. The extreme hardness of the 75% copper, 25% nickel alloy caused frequent die failures and resulted in many coins with incomplete details even when freshly struck. Distinguishing between a weakly struck uncirculated coin and a lightly circulated coin with full strike requires careful examination of both design details and surface characteristics.

Strike Quality vs. Wear: The Critical Distinction

Weak strikes lack detail despite full luster; circulated coins show surface flattening

A weakly struck uncirculated 1870 Shield Nickel may lack detail on the shield's vertical lines, the leaves above the shield, and the centers of reverse stars, yet it will retain its original mint luster—a rotating "cartwheel" effect visible when the coin is tilted under a light source. In contrast, a circulated coin shows rubbing or flattening of the highest surfaces and a disruption of luster on those same points, even if the strike was originally sharp. The market heavily favors well-struck examples, and a sharply detailed AU-58 coin can be more valuable and desirable than a weakly struck MS-62.

Circulated Grades (G-4 through AU-58)

Good (G-4): Heavy wear with the shield's design heavily worn and stripes mostly merged. The date "1870" is barely legible but must be readable to achieve this grade. Reverse stars are flat, with little to no interior detail visible. Rim is complete but may show minor wear into peripheral legends.

Very Good (VG-8 to VG-10): Moderate to heavy wear. Date is clear and readable. Shield outline is distinct, but vertical stripes are worn smooth or show minimal separation. Leaves above shield are visible but worn flat. Reverse stars show only faint interior details, if any.

Fine (F-12 to F-15): Moderate wear with roughly half the shield's vertical lines visible as distinct entities, though worn and shallow. Leaves show some separation but minimal interior detail. Reverse star centers are worn but most stars retain some interior features. "IN GOD WE TRUST" motto remains clearly legible with full letter separation.

Very Fine (VF-20 to VF-35): Light to moderate wear. Most shield lines are visible and separate, though worn and not deeply defined. Leaf outlines are clear with some interior veining visible. Reverse stars show more detail in centers, with most retaining partial interior lines. Overall design elements are well-defined with pleasing eye appeal.

Extremely Fine (EF-40 to EF-45): Light wear confined to the highest points. Shield lines are nearly complete with only slight wear on the highest vertical lines. Leaves show most interior details with only high points worn. Reverse star centers retain most details. A trace of original luster may be visible in protected areas.

About Uncirculated (AU-50 to AU-58): Only traces of wear visible on the absolute highest points: the horizontal top bar of the shield, the tips of leaves, and the centers of reverse stars. Most original mint luster remains (50-75% in AU-50, 75-90% in AU-55, over 90% in AU-58). The dividing line between AU-58 and MS-60 is often subtle and based on the presence of any detectible friction on high points under magnification.

Mint State Grades (MS-60 through MS-66+)

MS-60 to MS-62: No trace of wear, but surfaces may show numerous contact marks, hairlines, or other distractions from bag handling. Luster may be somewhat impaired or subdued. Strike quality can vary significantly—many examples in this range are weakly struck with incomplete shield details, which limits their grade potential despite full Mint State status.

MS-63 to MS-64: Moderate to minimal contact marks. MS-64 is noted by PCGS as the most frequently encountered Mint State grade for 1870, representing a population bottleneck. Luster should be better than in lower MS grades, ideally displaying a pleasing "cartwheel" effect. Strike quality becomes increasingly important—full shield lines and sharp star centers separate premium examples from those merely achieving the numerical grade.

MS-65 (Gem): Few contact marks, typically confined to inconspicuous areas. Luster must be full and vibrant. Strike quality is paramount at this level—incomplete shield lines or weak star centers will prevent a coin from reaching Gem status regardless of surface preservation. Only 75 examples are estimated at MS-65 or finer by PCGS, making this a genuinely rare grade for the issue.

MS-66 to MS-66+: Exceptional surfaces with only the most minor, insignificant marks. Luster must be outstanding with full "cartwheel" rotation. Strike must be complete and sharp on all design elements. These represent the finest known examples of the date, with PCGS having certified only a handful at MS-66+ and none higher. Eye appeal—the coin's overall visual attractiveness—becomes the dominant factor, explaining the wide auction price variance from $4,900 to $10,281 for certified MS-66 specimens.

Proof Grades (PF-60 through PF-67)

Proof coins are graded on a similar numerical scale but with different surface expectations. Fields must retain their mirrored finish, and any hairlines from cleaning or careless handling are heavily penalized. Cameo (CAM) and Deep Cameo (DCAM) designations are awarded when frosted devices contrast strongly against mirrored fields—these add significant value. At PF-65 and above, surfaces should be nearly pristine with vibrant mirrors and exceptional eye appeal. The wire rim—that sharp, squared-off edge characteristic of Proof strikes—must be fully intact and not damaged.

Die Varieties of the 1870 Shield Nickel

FS-301: The famous Indian Cent die clash visible within the shield's stripes

The 1870 Shield Nickel is one of the most variety-rich dates in the entire series, with at least eight documented die varieties cataloged in the Cherrypickers' Guide to Rare Die Varieties (FS numbers) and Howard K. Fletcher's specialized work on Shield Nickels. These varieties result from errors during the die manufacturing process—doubled dies, repunched dates, and in one famous case, a die clash with an Indian Head Cent die. Collectors actively seek these varieties, which command substantial premiums over regular 1870 nickels.

FS-301: Repunched Date with Indian Cent Die Clash (The "Mule Clash")

The 1870 FS-301 is the most famous and valuable variety of the date. During the die production process, the reverse die of an 1870 Shield Nickel was accidentally brought into contact (clashed) with an obverse die intended for an Indian Head Cent—a completely different denomination. This "mule" clash transferred a faint, incuse impression of the Indian Head profile into the working die, which then struck coins showing ghostly outlines of the Indian Head portrait within the vertical stripes of the shield on the nickel's obverse.

Attribution Diagnostics: Under magnification (a 5x to 10x loupe is recommended), the faint outline of an Indian Head profile can be seen within the vertical stripes of the shield, typically visible as curved lines that do not match the shield's geometry. The variety also exhibits clear repunching on one or more digits of the date "1870." Due to the subtle nature of the clash, proper lighting and magnification are essential for confident attribution.

Rarity and Value: This is an exceedingly rare variety that commands a substantial premium across all grades. PCGS Price Guide values suggest $750 in VF-20, $850 in VF-30, and $1,550 in AU-55. A PCGS VF-20 example realized $646 at Heritage Auctions in 2016. Current market estimates place values at $600-$850 in VF grades, escalating to $1,200-$1,600 or more in AU and Mint State grades. Given the variety's fame and scarcity, premium-quality examples can exceed these ranges significantly.

FS-101: Doubled Die Obverse & Repunched Date

The 1870 FS-101 is a desirable "two-fer" variety, exhibiting both a Doubled Die Obverse (DDO) and a Repunched Date (RPD). The doubling is most prominent on the letters of the motto "IN GOD WE TRUST," where a secondary, underlying impression is visible. The date also shows clear evidence of repunching, where one or more digits were initially punched into the die in a slightly incorrect position, then corrected, leaving visible secondary images.

Value Estimates: An uncertified example in Fine condition was offered at $104, while an ANACS-certified EF-40 carried an asking price of $699.99. An uncertified About Uncirculated example was listed at $1,500. Based on available data, a reasonable market value range is $100 or more in low circulated grades, escalating to over $1,500 in AU and higher grades.

FS-801: Doubled Die Reverse

The 1870 FS-801 is considered one of the top die varieties in the entire Shield Nickel series. Bold doubling is visible on the reverse, particularly on the stars and the letters of "CENTS." The doubling is dramatic enough to be seen with the naked eye on well-preserved examples, though magnification aids in confirming the attribution.

Value Estimates: Pricing data shows some variance. Dealer listings include an uncertified Fine at $80, a VF at $100, an ICG-graded AU-53 at $749.95, and a PCGS MS-63 at $1,575. However, a Heritage Auctions sale of a PCGS MS-63 realized only $372, suggesting significant price variance based on eye appeal and venue. Conservative estimates place values at $80-$150 in circulated grades, $700+ in AU, and potentially exceeding $1,500 in premium Mint State examples.

Additional Documented Varieties

The following varieties are documented but have limited public pricing information available:

• FS-102 (DDO & DDR): Doubling visible on both obverse motto and reverse elements. An ANACS VG-10 was listed at $490, indicating strong premiums even in low grades. Scarce.
• FS-103 (DDO): Doubling on obverse, typically within the motto. Scarce, but no reliable pricing available. Would carry a modest premium over a regular 1870.
• FS-302 (RPD): Standard Repunched Date variety with clear doubling of one or more date digits. Less dramatic than FS-301. Estimated premium: $50-$200 depending on grade and repunching visibility.
• FS-802 (DDR): A second Doubled Die Reverse variety, distinct from FS-801. An uncertified circulated example was offered at $140. Aggregated online sales data suggests $240 in VF and $290 in AU for generic "Double Die" 1870 nickels.
• F-08 (DDO): A Doubled Die Obverse variety attributed by Howard K. Fletcher. Likely scarce, as are most Fletcher-attributed varieties. No specific pricing available.

Mint Errors on 1870 Shield Nickels

Beyond the die varieties created during die manufacturing, individual 1870 Shield Nickels can exhibit mint errors that occurred during the striking process. These are unique, non-repeatable flaws that can add significant value to a coin. While specific auction records for 1870-dated errors are limited, values can be estimated based on error types commonly encountered across the Shield Nickel series.

Off-Center Strikes

An off-center strike occurs when the planchet is not properly seated between the dies during striking, resulting in a portion of the design being struck off the edge of the coin. The value is determined by (1) the percentage the coin is off-center and (2) the visibility of the date.

Value Estimates: A minor off-center strike (5-10%) might add a premium of $50-$150. A more dramatic strike (20-40%) with a full date could be worth $200-$400. A 50% off-center strike, where half the coin is blank but the date "1870" is fully present, is highly desirable to error collectors and could command $500 or more. If the date is not visible, values drop significantly.

Die Cracks and Cuds

The extreme pressure and hardness of the copper-nickel alloy caused Shield Nickel dies to crack frequently. These cracks transfer to the coin as raised, jagged lines running across the surface. Minor die cracks are very common on Shield Nickels and add little to no value—they are considered a characteristic of the series rather than a collectible error.

Valuable Die Failures: Extensive, intersecting cracks creating a "shattered die" appearance are scarcer and more desirable. A "cud"—where a significant piece of the die breaks away, leaving a raised, unstruck blob of metal at the coin's rim—is much rarer. A prominent cud or dramatic shattered die error could add $40-$100 or more to the coin's value, depending on size and visual impact.

Lamination Errors

Lamination errors result from impurities or gas trapped within the metal of the planchet during the rolling process. This can cause a piece of the coin's surface to flake or peel away. A small lamination flaw adds little value. A large, detached flake will typically devalue the coin as it creates an unsightly appearance.

Retained Laminations: The most collectible form is a "retained lamination," where a large piece of the metal layer is peeling up but still attached to the coin. This creates a dramatic, three-dimensional error that is desirable to error collectors. Depending on size and location, a retained lamination could add $30-$75 to the coin's value.

Struck-Through Errors

A struck-through error occurs when a foreign object comes between the die and the planchet during striking, transferring the object's shape onto the coin's surface. Common struck-through errors involve grease filling the die, resulting in weak or missing details—these add minimal value as they are common and unattractive.

Interesting Strike-Throughs: Struck-through errors involving more unusual objects—such as a piece of cloth, a wire bristle from a die-cleaning brush, or a coin fragment—are much rarer and more valuable. Depending on the clarity of the impression and the nature of the object, values can range from $20 for minor examples to several hundred dollars for dramatic, well-preserved strike-throughs with clear diagnostic features.

Major Errors: Brockages and Die Caps

These are among the most dramatic and rare error types in numismatics. A brockage occurs when a struck coin fails to eject from the press and is then pressed into the next planchet, creating a sunken, mirror-image impression of the coin's design. A die cap occurs when a coin adheres to one die and strikes subsequent planchets while still attached, becoming progressively deformed into a bottle-cap shape.

Value Potential: These major errors are highly prized and seldom seen on 19th-century coinage. If an 1870 Shield Nickel with such an error were to appear on the market, it would likely be valued at several thousand dollars, with prices ranging from $500 to $5,000 or more depending on the error's severity, the coin's underlying condition, and collector demand at the time of sale.

Authentication and Counterfeit Detection

Cleaning destroys value—original surfaces show natural luster, not artificial brightness

While common, circulated 1870 Shield Nickels in lower grades are not typically targets for counterfeiters due to their modest values, high-value specimens face authentication challenges. The primary targets are Gem Mint State coins (MS-65 and above), high-grade Proofs (particularly those with Cameo designations), and major varieties like the FS-301 Indian Cent clash. Additionally, cleaned or altered coins represent a significant authentication concern, as improper cleaning can reduce a coin's value by 50% to 75% or more.

Physical Specifications: A genuine 1870 Shield Nickel should weigh exactly 5.00 grams with a tolerance of ±0.05 grams and measure 20.50 mm in diameter. The copper-nickel alloy (75% copper, 25% nickel) has a distinct, slightly yellowish-gray appearance that is difficult to replicate perfectly. Counterfeits may have incorrect weight, a soapy or unnatural luster, or weak, poorly defined details that do not match known die states.

Variety Authentication: For die varieties—especially the valuable FS-301 clash—the diagnostic markers must match known examples precisely. The faint Indian Head outline in the FS-301 should appear in specific locations within the shield's stripes and exhibit the characteristic shape of an Indian Head Cent portrait. Any variety purporting to be rare should be compared against published photographs in the Cherrypickers' Guide or PCGS CoinFacts before purchase. Varieties certified by PCGS, NGC, or ANACS with the specific FS number on the certification label provide the highest level of authentication and market acceptance.

Altered Date Detection: While less common on 1870 nickels (which are not particularly rare), altered dates are a concern across the Shield Nickel series for key dates. The date "1870" should be examined under magnification for any tool marks, unusual shapes of digits, or evidence of re-engraving. The font and punch position should match known genuine examples. Any suspicious date numerals warrant expert examination.

Cleaned Coin Detection: Abrasive cleaning to artificially brighten a coin's surface is one of the most common problems affecting Shield Nickels. Telltale signs include a uniform, unnaturally bright appearance that lacks the varied toning patterns of natural aging; a complete loss of original mint luster, leaving surfaces dull and lifeless; and fine, parallel scratches (hairlines) visible under magnification, especially in the fields. Chemical dipping can strip the surface, leaving it with an unnatural, etched appearance. Any coin exhibiting these characteristics will be designated as a "details" or "genuine—cleaned" coin by grading services and will trade at a substantial discount—typically 50% to 75% below the value of a problem-free coin of equivalent wear.

Problem Coin Identification: Beyond cleaning, heavily circulated or mishandled coins are prone to scratches, rim dings or dents, corrosion (visible as pitting or green/brown residue, particularly in recessed areas), and bending (the coin not lying flat when placed on a table). Environmental damage, such as exposure to PVC plastic holders, can leave green, sticky residue on surfaces. Any of these problems will significantly reduce value and may render a coin uncollectible to many buyers.

Professional Certification: For any 1870 Shield Nickel valued at several hundred dollars or more—particularly Mint State examples, Proofs, major varieties, or any coin being considered for significant investment—professional authentication and grading by PCGS or NGC is strongly recommended. Certification provides a guarantee of authenticity, protects against counterfeits and problem coins, delivers an expert opinion on grade that is widely accepted in the marketplace, and significantly enhances liquidity when selling. The modest certification fee (typically $20-$40 per coin at standard service levels) is a sound investment that protects against costly authentication errors.

Preservation and Care of Your 1870 Shield Nickel

Proper storage and handling are essential to protecting the condition and value of any numismatic specimen. Shield Nickels, despite their hard copper-nickel alloy, are susceptible to surface damage from improper care. Following best practices ensures your 1870 Shield Nickel retains its grade and eye appeal for future generations.

Handling: Always hold coins by their edges between the thumb and forefinger—never touch the obverse or reverse surfaces. Human skin naturally contains oils and acids that, when transferred to a coin, can cause permanent spots, fingerprints, and toning that reduces eye appeal and grade. For high-value coins, consider wearing cotton or nitrile gloves during examination. Handle coins over a soft surface (such as a felt pad) to prevent damage if accidentally dropped.

Storage for Raw (Uncertified) Coins: The most important factor is using inert, archival-quality holders. For individual coins, 2x2 cardboard holders with Mylar windows ("2x2 flips") are safe and inexpensive. Avoid soft, flexible plastic flips made of polyvinyl chloride (PVC)—PVC degrades over time and leaches chemicals that cause a green, oily residue and permanent surface damage to coins. If you are uncertain whether a flip contains PVC, discard it and transfer the coin to a confirmed Mylar holder. For long-term storage of multiple coins, archival coin albums with inert plastic pages (such as those made by Dansco or Whitman) provide organization and protection.

Storage for Certified (Slabbed) Coins: Coins certified by PCGS, NGC, or ANACS are encapsulated in hard, inert plastic holders (slabs) that provide excellent long-term protection. These can be stored in specialized slab boxes or album pages designed for certified coins. The sonic-sealed holders are airtight and protect against environmental exposure, though they should still be kept in a stable environment.

Environmental Conditions: Store all coins in a cool, dry location with stable temperature and low humidity. Extreme temperature fluctuations, high humidity (above 50-60%), and exposure to pollutants can accelerate toning, corrosion, or surface degradation. Avoid storing coins in basements prone to flooding, attics with temperature extremes, or near sources of sulfur or chlorine (which cause toning). A climate-controlled room or a safe deposit box at a bank provides optimal conditions. For particularly valuable collections, desiccant packets (silica gel) can be placed in storage containers to absorb excess moisture.

What NOT to Do: Never clean a coin. Cleaning—whether by abrasive rubbing, chemical dipping, or ultrasonic methods—invariably damages the surface and reduces value, often dramatically. If you believe a coin is dirty or tarnished, consult a professional conservator or numismatic expert before taking any action. Never store coins in paper envelopes (sulfur in paper can cause toning), direct contact with cardboard (acidic), or any plastic that is not explicitly labeled as archival or coin-safe. Avoid displaying coins in areas with direct sunlight, as UV exposure can cause fading or surface changes over time.

Recent Auction Results for 1870 Shield Nickels

Auction records provide valuable insight into real-world market prices and collector demand for the 1870 Shield Nickel across different grades and strike types. The following table presents representative auction results from major numismatic auction houses, demonstrating the price ranges achieved by certified examples in recent years.

Analysis: The auction results reveal significant price variance within the same grade, particularly at the MS-66 level where prices range from $4,900 to $10,281. This spread reflects the importance of strike quality and eye appeal—two coins with identical numerical grades can command vastly different prices based on these subjective factors. The strong result of $1,080 for a PR-65 Cameo versus typical guide values of $700-$1,000 for non-Cameo PR-65 specimens demonstrates the 30-50% premium collectors pay for desirable designations. Variety premiums are evident in the $646 result for an FS-301 in VF-20, representing roughly 6-8 times the value of a regular VF-20 example.
