2010 Lincoln Shield Cent Value: P, D, S Mint Guide

2010 Lincoln Shield Cent: Modern Conditional Rarity

The 2010 Lincoln Cent marks a significant design transition in American coinage. This year introduced the Union Shield reverse—a design by Lyndall Bass symbolizing President Lincoln's preservation of the United States as a unified nation. The new reverse replaced the 2009 Bicentennial commemorative designs and continues to the present day. The familiar Victor David Brenner obverse portrait of Lincoln, used since 1909, remained unchanged.

With a combined mintage exceeding four billion business strikes from the Philadelphia and Denver mints, plus 1.69 million San Francisco proofs and 583,897 special Satin Finish strikes, this coin represents a textbook case of conditional rarity. Circulated examples hold no numismatic value beyond face value. The entire collectible market focuses on "Top-Pop" specimens—coins preserved in the absolute highest grades and certified by professional services like PCGS or NGC.

This guide provides comprehensive market analysis across all three strike types (business, proof, and satin finish), detailed grading diagnostics for the copper-plated zinc composition, documented die varieties and mint errors, and preservation strategies critical to maintaining the valuable Red (RD) color designation. Market data includes retail price tables and verified auction records through October 2025.

How to Identify Your 2010 Lincoln Shield Cent

Obverse Design (Front)

The obverse retains Victor David Brenner's iconic 1909 portrait of Abraham Lincoln facing right. Key inscriptions include "LIBERTY" positioned to the left of Lincoln's profile, "IN GOD WE TRUST" arced above his head, and the date "2010" to the right of the portrait. The mint mark, when present, appears on the obverse directly below the date.

Reverse Design (Back)

The reverse features the Union Shield design by Lyndall Bass, sculpted by Joseph Menna. The shield displays 13 vertical stripes representing the original states, joined by a horizontal bar inscribed "E PLURIBUS UNUM" symbolizing federal unity. "UNITED STATES OF AMERICA" curves along the top rim, while a decorative scroll bearing "ONE CENT" drapes across the shield's base. Designer initials are present: "LB" (Lyndall Bass) appears on the lower right of the shield just above the rim, while "JFM" (Joseph Menna) is located on the lower left.

Mint Marks and Production Facilities

The 2010 Lincoln Cent was produced at three U.S. Mint facilities, identifiable by their mint marks:

• 2010 (P) - Philadelphia: No mint mark appears on business strikes and satin finish strikes from Philadelphia
• 2010-D - Denver: "D" mint mark below the date
• 2010-S - San Francisco: "S" mint mark below the date, found exclusively on proof strikes

Strike Type Identification

Three distinct strike types exist for 2010, each with characteristic surface finishes:

Business Strike (MS): Produced for circulation at Philadelphia and Denver. Genuine uncirculated examples exhibit "cartwheel luster"—a rotating, radial shimmer visible when the coin is tilted under a single light source. Surfaces are reflective and typically show contact marks ("bag marks") from striking and handling processes.

Proof (PR): Struck at San Francisco exclusively for collectors in 2010 Proof Sets. These coins display intensely mirror-like fields (flat background areas) paired with sharply detailed, frosted devices (raised design elements like Lincoln's portrait and the shield). This high-contrast finish is designated Deep Cameo (DCAM) or Ultra Cameo (UCAM) by grading services and represents the market standard for modern proofs.

Satin Finish (SP): Issued only in 2010 U.S. Mint Uncirculated Sets from Philadelphia and Denver. This special strike exhibits a distinctive non-reflective, matte appearance. Both fields and devices display a soft, "pearly" texture. The finish lacks the cartwheel luster of business strikes and the mirror surfaces of proofs. The 2010 satin finish coins represent a one-year-only combination of the new Union Shield design with the Satin Finish program, which was discontinued after 2010.

2010 Lincoln Shield Cent Price Guide

The 2010 Lincoln Shield Cent market demonstrates extreme grade sensitivity. With over four billion business strikes produced, circulated coins hold no premium. Value concentrates entirely in certified high-grade specimens, where population scarcity drives exponential price increases. The following tables synthesize retail price guide data and documented auction records through October 2025. Values shown are for coins with the critical Red (RD) color designation; Red-Brown (RB) and Brown (BN) examples trade for small fractions of these prices.

2010 (P) Business Strike (Philadelphia, No Mint Mark)

Mintage: 1,963,630,000

Auction Record: A 2010 (P) Lincoln Shield Cent graded MS-67 RD realized $1,375.00. The MS-68 RD grade represents the practical ceiling for business strikes due to high-speed modern minting processes that inevitably impart contact marks.

2010-D Business Strike (Denver)

Mintage: 2,047,200,000

Auction Record: A 2010-D Lincoln Shield Cent graded PCGS MS-67 RD achieved $4,994.00(PCGS, 2013). This record demonstrates the extreme premium commanded by top-population coins. While Gem (MS-65) specimens are readily available, Superb Gem (MS-67) examples are conditionally rare, and Perfect (MS-70) business strikes are virtually non-existent.

2010-S Proof Strike (San Francisco)

Mintage: 1,689,216

Modern proof coins are valued almost exclusively with the Deep Cameo (DCAM) or Ultra Cameo (UCAM) designation, which indicates sharp contrast between mirror-like fields and frosted devices. Standard Proof (RD) and regular Cameo (CAM) examples are considered inferior and trade at discounts. The proof market is defined by the steep value cliff between the common PR-69 grade and the perfect PR-70 grade. PCGS population data shows approximately 6,324 coins graded PR-69 DCAM compared to only 580 in PR-70 DCAM—an 11-to-1 rarity ratio that drives the premium.

Auction Record: A 2010-S Lincoln Shield Cent graded PCGS PR-70 DCAM realized $507.00(PCGS CoinFacts). The PR-69 DCAM grade represents the common high grade for this issue, while PR-70 DCAM specimens are conditionally scarce.

2010 (P) & 2010-D Satin Finish (Special Strike)

Mintage: 583,897 (combined, representing total 2010 Uncirculated Mint Set sales)

These Special Strike (SP) coins represent the most numismatically significant issue of 2010. They were sold exclusively in 2010 U.S. Mint Uncirculated Sets—not released into circulation and not included in Proof Sets. The 2010 Satin Finish is a one-year-only type: 2010 was both the inaugural year of the Union Shield reverse and the final year the U.S. Mint used the special Satin Finish for its uncirculated sets. The finish, created by sandblasting dies and striking burnished planchets, produces a distinctive soft, matte, or "pearly" appearance—neither the cartwheel luster of business strikes nor the mirror finish of proofs.

The SP-69 RD grade represents the top-population for this strike type, with SP-70 examples approaching zero population. The low mintage (relative to business strikes) and unique strike type make these coins particularly appealing to type set collectors and specialists in modern mint products.

Grading the 2010 Lincoln Shield Cent

The 2010 Lincoln Cent presents unique grading challenges inherent to copper-plated zinc composition and modern high-speed minting. Unlike earlier solid copper cents, the thin copper plating can reveal the underlying zinc core through wear or corrosion. Grading standards also differ significantly between the three strike types (business, proof, and satin finish), each with distinct surface characteristics and evaluation criteria.

High-Wear Points and Diagnostic Areas

For circulated business strikes, wear first appears on the highest points of the design. On the obverse, examine Lincoln's cheekbone, jawline, and the hair details above his ear. On the Union Shield reverse, the horizontal bar inscribed "E PLURIBUS UNUM" shows the earliest wear, followed by the vertical stripes of the shield. However, with over four billion business strikes produced and no numismatic value in circulated grades, detailed wear analysis is primarily academic—circulated 2010 cents are worth face value regardless of grade.

Uncirculated Business Strikes (MS Grades)

The market for 2010 business strikes focuses entirely on uncirculated (Mint State) grades MS-63 through MS-68. Grading at these levels evaluates luster quality, surface preservation, and the critical Red (RD) color designation.

MS-63 to MS-64 (Choice Uncirculated): Full mint luster is present with typical cartwheel rotation under light. Surfaces show moderate contact marks from minting and handling. These grades are readily available and represent common submissions to grading services. An MS-63 RD coin might have several noticeable marks in the obverse field, while MS-64 RD shows fewer and less prominent marks.

MS-65 to MS-66 (Gem Uncirculated): Luster remains strong and attractive. Contact marks are minimal and, in the case of MS-66, confined to non-focal areas. At the MS-66 level, surfaces approach the quality expected of premium modern coins. High-speed minting equipment inevitably creates some imperfections, making truly flawless surfaces exceptionally rare.

MS-67 to MS-68 (Superb Gem): These grades represent conditional rarity. MS-67 coins show virtually pristine surfaces with only the most minor imperfections visible under magnification. MS-68 specimens are near-perfect, with no distracting marks and exceptional eye appeal. At this level, grading becomes highly subjective, and even minor differences in mark placement or luster quality affect the assigned grade. Population reports confirm MS-67 and MS-68 examples are scarce, commanding significant premiums.

Proof Strikes (PR Grades)

Proof coins are evaluated on different criteria than business strikes, with emphasis on contrast quality (cameo designation) rather than contact marks. Modern proof production uses specialized dies and planchets to achieve mirror-like fields paired with frosted devices.

PR-65 to PR-68: These grades indicate full proof characteristics with increasingly better preservation. Minor handling marks may be present but should not detract significantly from eye appeal. For modern proofs like 2010-S, grades below PR-69 are generally considered inferior and trade at discounts.

PR-69 (Near-Perfect Proof): This is the common high grade for 2010-S proofs. A PR-69 DCAM coin exhibits superb mirror fields and sharp device frost with minimal imperfections. One or two minuscule marks may be present but are difficult to locate without magnification. Population data shows this grade is plentiful, making it the standard for collectors.

PR-70 (Perfect Proof): No imperfections are visible even under 5x magnification. The coin displays flawless mirror fields, perfect device frost, and exceptional strike quality. The 11-to-1 rarity ratio between PR-69 and PR-70 for 2010-S DCAM coins creates the steep value premium, with PR-70 examples trading at 3-8 times the price of PR-69.

Satin Finish (SP Grades)

Satin Finish coins are graded using Special Strike (SP) designations. The matte, non-reflective surface requires different evaluation criteria from either business strikes or proofs. Graders assess the quality and uniformity of the satin texture rather than cartwheel luster or mirror fields.

SP-65 to SP-67: Full satin finish is present with increasingly better surface preservation. At SP-67, contact marks should be minimal and non-distracting. These grades are relatively common for 2010 satin finish cents.

SP-68 (Choice Satin Finish): This represents the common high grade for the issue. Surfaces are nearly pristine with exceptional satin texture uniformity. Minor imperfections may be present but do not detract from overall eye appeal.

SP-69 (Superb Satin Finish): This is the top-population grade for 2010 satin finish cents. Only the most minimal imperfections are present, typically requiring magnification to detect. The unique one-year status of this strike type makes SP-69 RD specimens particularly desirable to specialists.

Strike Quality Considerations

Beyond surface preservation, strike quality affects grade assignment. Weak strikes—where design details are not fully formed—receive lower grades even if surfaces are pristine. For 2010 cents, examine the designer initials (LB and JFM on the reverse) and the fine details of Lincoln's hair. Well-struck examples show complete detail transfer from the dies. Modern minting technology generally produces strong strikes, but weak strike examples do exist and trade at discounts.

The Critical Importance of Color Designations

For copper and copper-plated coins, color designation fundamentally determines value. The three designations are:

• RD (Red): Coin retains 95% or more of its original mint red/orange color. This designation is essential for maximum value.
• RB (Red-Brown): Between 5% and 95% original red color remains, with brown oxidation visible.
• BN (Brown): Less than 5% original red color, predominantly brown oxidation.

As price tables demonstrate, RD designation is not simply a premium—it represents the entire collectible value for modern cents. An MS-66 RD coin might be worth $40, while the same coin in MS-66 RB trades for under $5. Copper oxidation is irreversible and progressive. Environmental factors (humidity, sulfur exposure, holder materials) accelerate color change. Professional encapsulation in inert holders is the only reliable long-term preservation strategy for maintaining RD designation.

Authentication and Problem Identification

For 2010 Lincoln Shield Cents, the primary authentication concerns differ from earlier series. Outright counterfeits are virtually non-existent due to the coin's low face value and massive production quantities. However, collectors face two significant risks: variety misattribution and altered surfaces. Understanding these issues is critical for making informed purchasing decisions.

Variety Misattribution: Machine Doubling vs. True Doubled Dies

One common misidentification involves confusing worthless "machine doubling" with genuine doubled die varieties. Machine doubling is a form of strike chatter that occurs when the die bounces slightly during the striking process, creating a flat, shelf-like doubling that appears to "squeeze" out from letters or design elements. This is a common occurrence and adds no value. In contrast, true doubled dies are hubbing errors created when the master hub impresses the working die multiple times in slightly offset positions. Doubled die doubling shows rounded, well-defined separation between the original and doubled images. For 2010 cents, documented Wexler varieties (WDDO-001 through WDDO-005 and WDDR-001, WDDR-002) exist, but these are minor varieties with minimal market premiums. Unless certified by PCGS or NGC with specific attribution, assumed variety coins should be treated with skepticism.

Cleaned and Altered Surfaces

The far more common problem involves circulated coins that have been harshly cleaned or polished in an attempt to appear uncirculated. Cleaned coins are considered "damaged" in numismatic terms and cannot receive standard numeric grades from professional services. Instead, they are returned in "Details" slabs (e.g., "UNC Details - Cleaned"), which have no stable collector value. Identifying cleaned coins requires careful examination:

• Loss of Luster: Original cartwheel luster (on business strikes) or satin finish (on SP strikes) is destroyed by cleaning. The surface may appear unnaturally bright but lifeless, or it may be dull and gray. Cleaned copper often displays an unnatural "pink" or "salmon" color distinct from the original orange-red mint luster.
• Hairlines: Under magnification (5-10x), cleaned coins show fine, parallel scratches in the fields. These are the result of abrasive cleaning materials or polishing compounds. Hairlines cannot be removed and permanently damage the coin's surface.
• Residue and Spotting: Dirt or toning may be packed into protected crevices (like the corners of letters, around Lincoln's ear, or between shield stripes) while the open fields are bright white or pink. This pattern indicates aggressive cleaning that reached exposed surfaces but could not penetrate recessed areas.
• Unnatural Color Distribution: Original mint-red color fades gradually and naturally from the center outward as coins age. Cleaned coins may show abrupt color transitions or inconsistent color distribution that appears artificial.

Plating Damage and Zinc Core Exposure

The 2010 cent's copper-plated zinc composition creates unique authentication issues. If the thin copper plating is compromised through wear, corrosion, or mishandling, the underlying zinc core can be exposed. Zinc is highly reactive and corrodes rapidly when exposed to moisture or air, creating white or gray "zinc rot" that spreads and cannot be stopped. Coins with zinc core exposure or active zinc corrosion are considered damaged and have no collectible value beyond face value. Examine coins under magnification for any breaks in the copper plating, particularly at high points and edges.

When to Seek Professional Certification

For any 2010 cent claimed to be MS-66 RD or higher, SP-68 RD or higher, or PR-69 DCAM or higher, professional certification from PCGS or NGC is essential. These services use consistent grading standards, sophisticated authentication techniques, and inert encapsulation to protect the coin's surfaces. The certification process includes verification of strike type, accurate color designation, and detection of cleaning or other alterations. While certification costs ($20-$40 per coin depending on service level) may seem high relative to the coin's base value, it provides essential market protection for premium-grade specimens. Uncertified coins claiming these grades should be assumed to be either overgraded or problem coins unless proven otherwise through independent evaluation.

Preservation and Storage

Preserving the Red (RD) color designation is the single most critical factor in maintaining a 2010 Lincoln Shield Cent's collector value. Copper is a highly reactive metal that oxidizes when exposed to air (specifically sulfur compounds) and humidity. This oxidation causes the original orange-red luster to fade progressively to red-brown (RB) and eventually brown (BN). Since the transition from RD to RB can reduce a coin's value by 80-90%, proper preservation is not optional for serious collectors.

Environmental Control

Store all copper coins in a cool, dry, and stable environment. Ideal conditions include temperature between 65-70°F (18-21°C) and relative humidity below 50%. Avoid areas with temperature fluctuations, high humidity, or exposure to sulfur sources (rubber bands, certain woods, wool, some cardboard). Basements and attics are generally unsuitable due to humidity and temperature variations. Climate-controlled interior spaces provide the most stable environment.

Holder Selection

Use only inert, archival-quality holders for long-term storage. Mylar (polyethylene terephthalate) flips are the industry standard for uncertified coins, providing excellent protection without chemical reactivity. Avoid "soft" PVC-based plastic holders, which leach plasticizers that attack copper surfaces and cause irreversible damage. PVC contamination appears as a green, sticky residue on the coin's surface and permanently destroys its value. When purchasing holders, verify they are explicitly labeled as "PVC-free" or "archival quality."

Professional Encapsulation

For any 2010 cent graded MS-66 RD or higher, SP-68 RD or higher, or PR-69 DCAM or higher, professional encapsulation by PCGS or NGC is the industry standard. These services seal coins in sonically welded, inert plastic holders that are virtually airtight. The holders use non-reactive plastics specifically engineered for long-term coin preservation. PCGS and NGC holders provide protection against environmental contamination, physical handling damage, and further oxidation. NGC offers a 10-year guarantee on its copper color designations, providing significant market protection for high-value RD coins. While encapsulation costs $20-$40 per coin, this investment is essential for preserving premium values that can reach hundreds or thousands of dollars.

Handling Best Practices

Handle coins as little as possible. When handling is necessary, hold coins by their edges only—never touch the obverse or reverse surfaces. Natural skin oils contain acids and contaminants that react with copper and leave fingerprints that cannot be removed without damaging the coin. Wear clean cotton or nitrile gloves when examining coins outside their holders. Work over a soft, clean surface to prevent damage if the coin is dropped. Never breathe directly on a coin's surface, as moisture from breath accelerates oxidation.

What Not to Do

Never attempt to clean a 2010 cent under any circumstances. Cleaning destroys original luster, creates hairline scratches, and results in Details-grade designation that eliminates all collector premium. Do not use commercial coin cleaning products, jewelry polishes, erasers, or abrasive materials. Do not wash coins in soap and water. Do not use compressed air, which can spray particles onto the coin's surface. If a coin appears dirty or toned, leave it alone—collectors prefer original surfaces, and any cleaning attempt will reduce value. For coins of significant value, consult a professional conservator if preservation concerns arise.

Frequently Asked Questions

Die Varieties and Attribution

The primary attribution systems for modern Lincoln Cent die varieties are the Wexler Doubled Die Files and CONECA (Combined Organizations of Numismatic Error Collectors of America) listings. For 2010 Lincoln Shield Cents, several minor doubled die varieties have been documented, though none are considered major varieties that command significant market premiums.

2010 (P) Doubled Die Obverse Varieties

Five obverse doubled die varieties are listed in the Wexler system for Philadelphia strikes:

2010 1¢ WDDO-001: Diagnostics show extra thickness on the letters of "LIBERTY." Notched corners are visible on the upper left of "ERTY." This is the most commonly referenced variety for 2010.

2010 1¢ WDDO-002: Similar to WDDO-001, displaying extra thickness on "LIBERTY," but the notching on the "R" and "T" is not as strong as the -001 variety.

2010 1¢ WDDO-003: Shows extra thickness on "LIBERTY" with notched corners visible on the lower left of "ERTY" rather than upper left as in -001.

2010 1¢ WDDO-004: Displays extra thickness on "ERTY" with notching on the bottom right of the letters rather than the left side.

2010 1¢ WDDO-005: Shows extra thickness on the digits of the date "2010" rather than on lettering.

2010 (P) Doubled Die Reverse Varieties

Two reverse doubled die varieties are documented for Philadelphia strikes:

2010 1¢ WDDR-001: Diagnostics show extra thickness on the designer's initials "LB" (Lyndall Bass) located on the lower right of the shield. A notch can be seen on the lower right of the "L."

2010 1¢ WDDR-002: Shows extra thickness on the designer's initials "JFM" (Joseph Menna) located on the lower left of the shield.

Market Valuation and Certification

No reliable public pricing is available from PCGS or NGC price guides for these specific 2010 Wexler-numbered varieties. The major grading services generally only recognize and attribute varieties that have significant market demand, typically designated with Fivaz-Stanton (FS) numbers. The absence of these 2010 varieties from standard industry price guides confirms they are minor varieties with minimal collector interest outside specialized die variety enthusiasts.

An uncertified 2010 variety coin carries little to no premium over a standard non-variety example. Even when certified and attributed by PCGS or NGC, a specimen graded MS-65 RD might trade for a modest premium of approximately $20-$40 over the standard coin value. This limited premium reflects the minor nature of these varieties and their lack of mainstream collector demand.

Authentication Warning: Machine Doubling

A critical distinction must be made between genuine doubled die varieties and worthless "machine doubling." Machine doubling is a common form of strike chatter that occurs when the die bounces slightly during the striking process. It creates a flat, shelf-like appearance that seems to "squeeze" out from letters or design elements. This phenomenon adds no value and is frequently mistaken for genuine doubled dies by inexperienced collectors. True doubled dies show rounded, well-defined separation between the original and doubled images, created when the master hub impresses the working die multiple times in slightly offset positions during the die-making process. Unless a 2010 cent is certified by PCGS or NGC with specific variety attribution, assumed variety coins should be treated with skepticism and are unlikely to carry any premium.

Mint Errors and Valuation

Modern coins like the 2010 Lincoln Shield Cent are subject to rigorous quality control during production, which paradoxically can make significant errors that escape the mint rarer and more valuable than their counterparts from earlier eras. The copper-plated zinc composition also creates unique error types not seen on earlier solid copper cents. Error coin values depend heavily on visual drama, rarity, and proper certification by services like PCGS or NGC.

Plating-Specific Errors

Plating Bubbles, Blisters, and Lamination: The thin copper plating over the zinc core is susceptible to adhesion problems. Plating bubbles appear as raised areas where the copper has separated from the zinc. Lamination occurs when pieces of the plating or zinc core flake off, leaving exposed areas. These errors are relatively common and typically add minimal value ($1-$5) unless exceptionally large or dramatic. Collectors should verify that exposed zinc has not begun to corrode ("zinc rot"), which would eliminate any premium.

Die Break Errors

Minor Die Cracks: Small interior die cracks are common occurrences in modern minting. These appear as raised lines on the struck coin where metal flowed into cracks in the die surface. A minor crack, such as the "Cracked Skull" variety showing a crack through Lincoln's head, adds modest value of $5 to $25 depending on prominence and collector interest. These are more curiosities than significant errors.

Cud (Major Die Break): A cud is a severe die break where a piece of the die at the rim breaks completely away, resulting in a raised, blank "blob" of metal on the coin's edge where the die break occurred. The larger the cud and the more dramatic its appearance, the more valuable the error. Cuds typically trade in the range of $100 to $300+, with values climbing for particularly large or well-positioned examples.

Striking Errors

Off-Center Strike: This error occurs when the planchet is not properly seated in the collar during striking, causing the design to be struck off-center. The key factor affecting value is whether the date and mint mark remain visible—without these, authenticity and attribution become problematic. A 10-20% off-center strike with date and mint mark visible trades for $10 to $20. A more dramatic 50% off-center example commands $30 to $75. Extreme off-center strikes (70-80%) with date visible can exceed $100.

Broadstrike: This error happens when the coin is struck without the retaining collar, allowing the metal to spread outward. The result is a coin that appears larger in diameter and flatter than normal, with the design fully struck but expanded. Broadstrikes typically trade for $20 to $50, with values varying based on how uniform the expansion is and overall eye appeal.

Major and Rare Errors

Multiple Strike: This dramatic error occurs when a coin is not properly ejected from the press after the first strike and is struck two or more times by the dies. The result shows overlapping images, often at different angles, creating a visually striking error. Multiple strikes are rare and valuable, typically commanding $500 to $2,000+ depending on the number of strikes and clarity of the overlapping images. A 2010-D "Multiple Struck Error" has been offered for sale at $2,018, demonstrating the premium these errors achieve.

Wrong Planchet Error: This extremely rare error occurs when a cent is struck on a planchet intended for a different denomination, such as a dime or foreign coin. No reliable public pricing is available for a 2010 example because such errors are major discoveries when they occur. Based on comparable wrong planchet errors from other recent years, a 2010 cent struck on a silver-colored dime planchet (2.268 grams) would be valued well over $1,000 and could reach several thousand dollars at auction. The dramatic difference in size, weight, and metal composition makes these errors highly collectible.

Error Authentication and Certification

Error coin collecting requires careful authentication because post-mint damage can sometimes mimic genuine errors. Off-center strikes must show collar marks at the properly struck edge. Broadstrikes should show uniform expansion without evidence of post-mint bending or alteration. Die cracks and cuds must be raised (showing metal flow into the die break) rather than incuse (which would indicate post-mint damage). For any error valued above $100, professional certification by PCGS or NGC Error Division is strongly recommended. These services verify authenticity, assign error designations, and provide market-accepted authentication that protects both buyer and seller.
