1998 Lincoln Cent: An Extreme Value Dichotomy
1998 Lincoln Cent obverse and reverse design
The 1998 Lincoln Cent presents one of modern numismatics' most dramatic value splits. With over 10.2 billion business strikes produced at Philadelphia and Denver, the vast majority are worth exactly one cent. Yet this same year produced two of the most valuable modern cent varieties, created when the U.S. Mint accidentally swapped proof and business strike reverse dies.
The result: common 1998 cents sit in pocket change, while rare "Wide AM" business strikes command up to $6,000, and the "Close AM" proof error reaches $5,160 in perfect condition. This 500,000% value differential makes the 1998 cent essential for variety hunters to understand.
This guide covers identification diagnostics for both varieties, complete pricing across all grades and mints, the critical role of color preservation on copper-plated zinc coins, and authentication techniques to avoid counterfeits.
Identifying Your 1998 Lincoln Cent: Mint Marks and Die Varieties
The 1998 Lincoln Cent was struck at three facilities, producing five distinct collectible issues once die varieties are considered. Accurate identification requires examining both the mint mark and the reverse die characteristics.
Mint mark locations: Philadelphia (no mark), Denver (D), San Francisco (S)
Mint Mark Locations
On all 1998 Lincoln Cents, mint marks appear on the obverse (front), positioned directly below the date:
- 1998 (P): No mint mark indicates Philadelphia Mint production. This is standard for Lincoln Cents, which only received a "P" mint mark in 2017 for the 225th anniversary.
- 1998-D: The letter "D" appears below the date, indicating Denver Mint production.
- 1998-S: The letter "S" appears below the date on proof-only issues from San Francisco.
Critical Die Variety Identification: Close AM vs Wide AM
The entire numismatic value of 1998 cents centers on two reverse die types, officially designated RDV-007 (business strike die) and RDV-006 (proof die). These dies were accidentally mixed, creating valuable transitional varieties.
Critical variety diagnostic: Close AM (common) vs Wide AM (rare on business strikes)
Primary Diagnostic: AM Spacing in AMERICA
- Close AM (RDV-007): The letters A and M in "AMERICA" are very close together, nearly touching. This is the standard die for all 1998-P and 1998-D business strikes and creates the rare 1998-S proof variety.
- Wide AM (RDV-006): The letters A and M show a clear, distinct gap between them. This is the standard die for 1998-S proofs and creates the rare 1998-P business strike variety.
🔍 Authentication Tip
AM spacing alone is not sufficient for authentication. Counterfeiters replicate the Wide AM spacing but often fail to copy the secondary FG diagnostic correctly. Always verify both features.
Secondary diagnostic: FG initials differ between proof and business strike dies
Confirmatory Diagnostic: FG Designer Initials
The "FG" initials (for designer Frank Gasparro) appear at the lower right of the Memorial. These provide crucial confirmation of die type:
- RDV-007 (Business Die / Close AM): The "G" lacks a prominent serif and is not flared. The FG is positioned slightly further from the Memorial base.
- RDV-006 (Proof Die / Wide AM): The "G" has a clear serif with a "flared" appearance. The FG is positioned noticeably closer to the Memorial base.
Magnification of 5-10x is necessary to properly examine both the AM spacing and FG details. Authentication of any raw 1998 variety should always include verification of both diagnostics.
Design Features
The 1998 Lincoln Cent continues the Memorial Reverse design introduced in 1959:
- Obverse: Victor David Brenner's 1909 portrait of Abraham Lincoln facing right, with "IN GOD WE TRUST" above, "LIBERTY" to the left, and the date below.
- Reverse: Frank Gasparro's 1959 design featuring the Lincoln Memorial with "UNITED STATES OF AMERICA" above, "E PLURIBUS UNUM" within the Memorial columns, and "ONE CENT" below.
1998 Lincoln Cent Price Guide: All Mints and Varieties

1998 (P) "Wide AM" Business Strike (FS-901) - KEY VARIETY
Estimated Population: Over 100,000 (PCGS estimate)
This scarce variety resulted from the accidental use of a proof reverse die (RDV-006) for business strikes at Philadelphia. It ranks as the second-scarcest of the 1998–2000 "Wide AM" transitional errors. Identification requires confirmation of both Wide AM spacing and the flared FG initials closer to the Memorial base.
⚠️ Counterfeit Alert
Replicas of the 1998 Wide AM are known. Counterfeits often replicate AM spacing but fail to correctly copy the FG initials. Always verify both primary and secondary diagnostics before purchasing raw coins.

Grading 1998 Lincoln Cents: Wear Patterns and Color Preservation
Accurate grading of 1998 Lincoln Cents requires understanding two distinct evaluation systems: wear-based grading for circulated coins (G-4 through AU-58) and strike quality plus preservation grading for mint state coins (MS-60 through MS-70). For business strikes, the color designation (Red, Red-Brown, or Brown) serves as a critical value multiplier that can create 300%+ premiums at the same numeric grade.
Grade comparison: circulated to uncirculated examples
Circulated Grade Characteristics
For the rare 1998 "Wide AM" variety found in circulation, wear follows predictable patterns based on the design's high points.
Key Wear Points on Obverse:
- Lincoln's cheek shows wear first, becoming flat and losing detail
- Jaw line loses definition as coin enters lower grades
- Hair above ear flattens and detail disappears
- Date remains visible through most circulated grades but becomes weak in Good condition
Key Wear Points on Reverse:
- Steps of the Lincoln Memorial show wear first
- Upper details of columns lose sharpness
- "AMERICA" lettering remains bold through most grades
🔍 Grade Reference
Very Fine (VF-20): Moderate wear visible but all major design elements clear. Lincoln's cheek shows flatness but jaw line distinct. Memorial steps partially worn but building structure clear.
About Uncirculated (AU-58): Slight wear on highest points only. Some original mint luster remains in protected areas. Lincoln's cheek shows minimal friction. Memorial steps mostly sharp.
Mint State Grade Characteristics
Uncirculated 1998 cents are graded on strike quality, surface preservation, eye appeal, and—critically—color retention. No wear is permitted on any design element for a coin to qualify as Mint State.
Strike Quality Assessment:
- Full detail on Lincoln's hair strands
- Complete definition of Memorial columns
- Sharp, squared rims without weakness
- Full separation of Memorial steps (though weak strikes are common)
Surface Preservation:
- MS-60 to MS-63: Noticeable contact marks, particularly on cheek and fields
- MS-64 to MS-65: Minor marks present but not distracting; overall pleasing appearance
- MS-66 to MS-67: Very few marks; exceptional eye appeal
- MS-68+: Virtually mark-free surfaces; superb strike and luster
Key areas to check for wear: Lincoln's cheek, jaw, and hair above ear
Color Designations: The Critical Value Multiplier
The copper-plated zinc composition of 1998 cents makes color preservation the single most important factor in determining mint state value. Grading services assign one of three color designations based on the percentage of original red copper color remaining.
Color preservation dramatically affects value: RD commands highest premiums
Red (RD): 85% to 90% or more of original mint red luster preserved. This designation requires nearly complete retention of the bright copper-red color with minimal toning or oxidation. Commands the highest premiums—a 1998 Wide AM in MS-65 RD is worth $85, versus $27 for the same grade in BN, representing a 300% premium for color alone.
Red-Brown (RB): Between 15% and 85% of original red color remains, with brown oxidation visible but red areas still present. Represents intermediate preservation. Values typically track close to BN grades in lower mint states but begin showing premiums in MS-66+.
Brown (BN): Less than 15% of original red remains. The coin shows predominantly brown oxidation from environmental exposure or aging. Represents the lowest color grade and commands the smallest premiums over common issues.
⚠️ Preservation Challenge
The copper-plated zinc composition makes 1998 cents inherently unstable. Zinc core corrosion ("zinc rot") can destroy the copper plating from beneath, creating bubbles, pits, and black spots. This chemical process turns RD coins into BN coins within years if improperly stored, eliminating the color premium entirely.
Proof Grade Characteristics
Proof 1998-S cents are graded on a separate scale (PR-60 through PR-70) that evaluates mirror field quality, device frosting, and surface preservation. Cameo designations add significant value:
Cameo (CAM): Noticeable contrast between frosted portrait/Memorial and mirror fields. Light to moderate frosting on devices.
Deep Cameo (DCAM): Strong, dramatic contrast with heavily frosted devices against brilliant mirror fields. This designation is standard for modern proofs and commands premium pricing, particularly for the rare 1998-S Close AM variety where a PR-70 DCAM is worth $4,850 versus much lower values without the designation.
Surface Quality:
- PR-67: Very minor imperfections visible under magnification
- PR-68: Minimal contact marks; nearly flawless
- PR-69: Virtually perfect; only one or two minute marks
- PR-70: Absolutely perfect under 5x magnification; no marks, spots, or imperfections
Die Varieties Beyond the Major Close/Wide AM
Beyond the two major Fivaz-Stanton (FS-901) transitional varieties, the 1998 cent has numerous minor Doubled Die Reverse (DDR) varieties cataloged by specialist organizations including CONECA and Variety Vista. These minor varieties are not attributed by major grading services (PCGS/NGC) and exist primarily in the specialist collector market.
1998-P Minor Doubled Die Reverses
Multiple minor DDR varieties have been documented for 1998-P cents, typically showing doubling on the Memorial's central columns. These varieties require magnification to identify and show very minor spreading or separation of design elements.
Market Status: Not listed in PCGS or NGC standard price guides. Uncirculated examples command modest premiums in the specialist market, typically in the $5 to $30 range depending on the strength of doubling and overall coin quality (eBay specialist listings).
1998-D DDR-001
Attribution: Variety Vista catalog designation
Diagnostics: "Medium spread... as two flutings of column #7" on the Memorial (Variety Vista). The doubling appears as a separation or extra outline on the seventh column from the left.
Value: Specialist item. Uncirculated examples trade in the $5 to $30 range in private sales and specialist auctions.
1998-D WDDR-002
Attribution: Wexler Die Varieties catalog designation
Diagnostics: "Doubling shows on the central left side of the 7th Memorial column" (Wexler's Coins). Similar to DDR-001 but with doubling concentrated on a different portion of the column.
Value: Specialist item with similar pricing to other minor 1998-D DDR varieties: $5 to $30 for uncirculated examples.
💡 Collector Note
Minor DDR varieties require careful examination with magnification and comparison to reference photos. These varieties are primarily of interest to specialists who collect comprehensive die variety sets rather than general Lincoln Cent collectors. Attribution services from CONECA or VarietyVista may be necessary for confirmation.
Distinguishing Minor Varieties from Die Polish Lines
Beginning collectors sometimes mistake normal die polish lines for doubled dies. Die polish lines are raised, non-parallel lines on the coin's surface resulting from the mint polishing the die. These are a normal part of the minting process and do not detract from grade or represent varieties. True doubled dies show actual separation or spreading of design elements, not random raised lines (YouTube: Die Polish Lines vs Hairlines).
1998 Lincoln Cent Mint Errors and Values
Beyond die varieties, production errors during the minting process create a distinct category of collectible 1998 cents. Error values are determined by the error type, severity, visual impact, and grade. Major errors command substantial premiums, while minor errors add modest value.
Major Error: Struck on Wrong Planchet (Dime Planchet)
The most significant documented error for 1998 cents involves coins struck on planchets intended for dimes. This wrong planchet error creates a visually dramatic coin with substantial collector demand.
Rare error: 1998 cent struck on dime planchet (silver color, smaller size)
Identification Diagnostics:
- "Silver" colored appearance (cupro-nickel clad composition of dime planchet)
- Underweight: approximately 2.3 grams versus normal 2.50 grams
- Smaller diameter: dime planchet is 17.9mm versus cent die diameter of 19.0mm
- Design truncation: the cent's design is partially cut off at the rims because the 19mm dies are too large for the 17.9mm planchet
- Incomplete rim formation
Documented Examples:
- A PCGS MS-64 example was offered in the specialist market for $1,000(MintErrors.org)
- A PCGS MS-67 example (described as "Superb Gem") was sold by Heritage Auctions in 2006 (Heritage Auctions, Lot 1968)
Market Context: The inverse error—a 1998-P dime struck on a cent planchet—realized $3,360 at Heritage Auctions in September 2024 (Mint Error News, 2024). This establishes strong market demand for cent/dime planchet swaps.
Estimated Value Range:$1,000 in MS-64 to over $3,500 in gem grades (MS-67+).
Die Cap with Double Strike
A documented 1998 cent "double struck and with the obverse die cap" sold at auction for $940(YouTube: 1998 Pennies Worth Money). This error type occurs when a struck coin adheres to the die and remains in place during subsequent strikes, creating a "cap" formation.
Rarity: Die caps are rare errors, and examples with multiple strikes showing clear details command strong premiums in the error coin market.
Off-Center Strikes
Off-center errors occur when the planchet is not properly centered between the dies during striking, causing part of the design to be missing and part of the planchet to remain blank.
Value Determinants:
- Percentage off-center: More dramatic errors (50%+ off-center) command higher premiums
- Date visibility: Errors with full date visible are more valuable than those with partial or missing dates
- Overall eye appeal and strike quality
Typical Values:
- Minor off-center (10% or less): $18 to $50(eBay: 10% Off-Center)
- Moderate off-center (25-50%): Higher premiums depending on date visibility
Broadstrike Errors
Broadstrikes occur when the coin is struck without the retaining collar in place, allowing the metal to spread beyond the normal diameter. The result is a coin with a larger diameter, no raised rim, and often with sharp, square edges where the metal spread during striking.
Typical Values:$30 to $45 for 1998 examples in uncirculated condition (eBay: Broadstrike Error).
💡 Error Coin Authentication
Significant errors should be authenticated by a major grading service (PCGS, NGC) or a recognized error coin specialist. Post-mint damage can sometimes mimic certain error types, and professional authentication protects against misattribution and ensures marketability.
Lamination Errors
Lamination errors occur when the thin copper plating separates or flakes off the zinc core. These appear as raised blisters, peeling areas, or missing plating patches on the coin's surface.
Prevalence: Common for copper-plated zinc cents due to the inherent instability of the plating process and the reactive nature of the zinc core.
Value: Minor lamination errors add minimal value, typically $5 to $20(Coin ID Scanner). Large, dramatic laminations showing significant metal separation can command slightly higher premiums.
Authenticating 1998 Lincoln Cents: Problem Coins and Counterfeits
Given the substantial premiums for 1998 die varieties—particularly the Wide AM business strike and Close AM proof—authentication is essential before purchasing raw coins. The market has seen both intentional counterfeits and honest misattributions that can cost collectors thousands of dollars.
Counterfeit Threats: Replicas of both the 1998 Wide AM and 1998-S Close AM varieties are documented in the marketplace (Proxiblog, 2024). Counterfeiters often successfully replicate the primary AM spacing diagnostic but fail to correctly reproduce the FG initials' font and positioning. This makes the FG diagnostic the most reliable confirmatory test for authentication.
Authentication Protocol for Raw Coins: Before purchasing any raw 1998 variety coin claiming to be a Wide AM or Close AM variety:
- Verify AM Spacing: Use 5-10x magnification to examine the space between A and M in "AMERICA." Close AM varieties show the letters nearly touching; Wide AM varieties show a clear gap.
- Confirm FG Initials: This is the critical confirmatory diagnostic. Check both the font (flared vs non-flared "G") and the position relative to the Memorial base (closer vs further). Counterfeits typically fail this test.
- Weight Verification: All genuine 1998 cents should weigh 2.50 grams. Significant deviations suggest either an error coin (wrong planchet) or a counterfeit.
- Consider Third-Party Certification: For any variety coin valued over $100, authentication and grading by PCGS or NGC provides insurance against counterfeits and adds marketability. The grading fee (typically $20-40) is a small cost compared to the risk of purchasing a $1,000+ counterfeit.
Cleaned Coin Detection: Cleaning destroys a coin's numismatic value and prevents it from receiving a straight grade from major services. Signs of cleaning include:
- Dull, lifeless surface that lacks the characteristic luster of mint state or natural toning (YouTube: Identifying Cleaned Copper Cents)
- Porous or etched appearance from harsh chemical cleaning
- Fine, parallel scratches ("hairlines") across the fields from abrasive polishing (Reddit: Identifying Cleaned Coins)
- Unnatural coloration, including bright "pink" or orange tones that don't match aged copper
Zinc Rot Identification: The copper-plated zinc composition creates a unique form of damage where the zinc core corrodes beneath the copper plating. This "zinc rot" manifests as:
- Raised bubbles or blisters on the surface where gas from zinc oxidation lifts the copper plating
- Black or dark green spots indicating active zinc corrosion
- Pitting or holes where the plating has completely failed and zinc has corroded away
- Powdery white or gray corrosion products on the surface
Zinc rot damage: plating bubbles, pits, and black spots from core corrosion
Coins with zinc rot are considered "problem coins" and have no collectible value regardless of variety or grade. The damage is irreversible and will continue to worsen over time. Never attempt to clean zinc rot, as acidic or abrasive cleaning will only accelerate the zinc corrosion and destroy the coin completely (wikiHow: Cleaning Pennies).
When to Buy Certified vs Raw: For common 1998-P and 1998-D cents in circulated condition, raw coins pose minimal risk as their value is face value or very modest. However, for any of the following situations, third-party certification is strongly recommended:
- Any coin claimed to be a Wide AM or Close AM variety
- Any mint state coin graded MS-66 or higher
- Any proof graded PR-69 or higher
- Any error coin valued over $100
- Any coin being purchased for investment rather than casual collecting
The cost of certification (typically $20-60 depending on service level) is justified by the authentication guarantee, grade accuracy, and enhanced marketability when selling. For variety coins valued over $500, the grading fee represents less than 10% of the coin's value and is essential protection against counterfeits.
Preserving Your 1998 Lincoln Cent Collection
The copper-plated zinc composition of 1998 cents creates unique preservation challenges. Unlike solid copper cents from 1909-1982 or solid silver coins, the zinc core is highly reactive and the thin copper plating provides only minimal protection against environmental damage. Proper storage is not optional for maintaining numismatic value—it is essential, particularly for preserving the "Red" (RD) color designation that creates 300%+ premiums in high grades.
The Zinc Rot Threat: The primary enemy of 1998 cents is moisture. Even moderate humidity can trigger zinc core oxidation, which produces gas that lifts the copper plating and creates bubbles, dark spots, and eventual pitting. This "zinc rot" is irreversible and will destroy a coin's value regardless of grade or variety. Once started, the corrosion is self-perpetuating and will continue to worsen over time.
Storage Environment Requirements: To prevent zinc rot and preserve color, 1998 cents must be stored in a controlled environment with low humidity (ideally below 40% relative humidity). Use archival-quality, inert holders such as acrylic slabs, capsules, or holders made from Mylar. Avoid PVC-based plastic "flips," which off-gas chemicals that can attack both the copper plating and the zinc core, turning Red coins Brown within months to years. Paper envelopes are also problematic as they absorb moisture and can promote oxidation.
Handling Best Practices: Never handle 1998 cents with bare hands. Skin oils, perspiration, and salt from fingers will attack the copper plating and can leave permanent fingerprints that destroy eye appeal and grade. Always use cotton gloves or hold coins by the edges only. When examining coins, work over a soft surface (cloth or felt pad) to prevent damage from accidental drops. Never slide coins across any surface, as this creates scratches that reduce grade.
Cleaning Prohibition: Do not clean 1998 cents under any circumstances. The copper-plated zinc composition is extremely sensitive to chemicals. Acidic cleaners such as vinegar, lemon juice, salt, or ketchup—sometimes recommended for solid copper pennies—will attack the zinc core, often turning the coin black and destroying it completely (wikiHow: Cleaning Pennies). Even mild soap and water can promote zinc corrosion. Professional conservation is available through grading services for valuable coins with specific problems, but home cleaning attempts always reduce value and are irreversible.
Color Preservation: The "Red" (RD) designation requires 85%+ retention of original mint red color. This color is unstable and will naturally fade to Red-Brown (RB) and eventually Brown (BN) over time through oxidation, even in ideal storage. To maximize color retention: (1) store in airtight holders to minimize air exposure, (2) maintain low humidity and stable temperature, (3) keep coins away from light sources (especially UV light), and (4) avoid any exposure to airborne pollutants, sulfur compounds, or chemical fumes. A coin stored properly in a certified holder may maintain Red color for decades; the same coin in a PVC flip or paper envelope may turn Brown within 5-10 years, losing hundreds or thousands of dollars in value.
Long-Term Value Protection: For valuable varieties (Wide AM, Close AM proof) or high-grade examples, third-party certification (PCGS, NGC) provides the best long-term preservation. Certified holders are sonically sealed, archival-quality, and provide protection from environmental damage while maintaining authenticity and grade documentation. For raw coins, annual inspection is recommended to check for early signs of zinc rot (bubbles, dark spots) so coins can be certified or moved to better storage before significant damage occurs.
Frequently Asked Questions About 1998 Lincoln Cents
How much is my 1998 penny worth?
Most 1998 pennies are worth face value (1 cent) in circulated condition. However, rare die varieties command substantial premiums: the 1998 Wide AM business strike is worth $10-$6,000 depending on grade and color, and the 1998-S Close AM proof is worth $180-$5,160. High-grade common business strikes in MS-67+ RD can also be worth $38-$3,000. Identification of the specific variety and accurate grading are essential to determine value.
How do I tell if my 1998 penny is a Wide AM or Close AM?
Examine the reverse under 5-10x magnification, focusing on the word "AMERICA." In Close AM varieties (common for 1998-P/D, rare for 1998-S proofs), the A and M nearly touch with minimal space. In Wide AM varieties (common for 1998-S proofs, rare for 1998-P business strikes), the A and M show a clear, distinct gap. Confirm by checking the FG designer initials: Wide AM has a flared "G" positioned closer to the Memorial base; Close AM has a non-flared "G" positioned further from the base.
Where is the mint mark on a 1998 penny?
The mint mark appears on the obverse (front) of the coin, directly below the date. 1998-D pennies have a "D" in this location (Denver Mint). 1998-S pennies have an "S" (San Francisco Mint, proof-only). 1998 pennies with no mint mark were struck at the Philadelphia Mint. The absence of a mint mark on a business strike is normal and indicates Philadelphia production.
Should I get my 1998 penny professionally graded?
Third-party grading (PCGS, NGC) is recommended if your coin is: (1) a suspected Wide AM or Close AM variety, (2) in apparent mint state condition MS-66 or higher, (3) a proof in PR-69 or higher, (4) an error coin valued over $100, or (5) being purchased/sold for investment purposes. Grading costs $20-60 but provides authentication, accurate grade determination, and enhanced marketability. For common circulated 1998 cents, grading is not cost-effective.
What is zinc rot and how do I prevent it?
Zinc rot is corrosion of the zinc core beneath the copper plating, caused by moisture exposure. It manifests as bubbles, dark spots, pitting, or holes in the coin's surface and is irreversible. Prevention requires: (1) storage in archival-quality, inert holders (acrylic capsules, certified slabs), (2) maintaining low humidity (below 40% relative humidity), (3) avoiding PVC-based flips or paper envelopes, and (4) keeping coins away from moisture sources. Once zinc rot begins, the damage is permanent and the coin loses all collectible value.
Can I clean my 1998 penny to make it look better?
No. Never clean a 1998 penny. The copper-plated zinc composition is extremely sensitive to chemicals. Acidic cleaners (vinegar, lemon juice, salt) will attack the zinc core and often turn the coin black, destroying it completely. Abrasive cleaning creates scratches ("hairlines") that prevent the coin from receiving a straight grade from grading services. Even soap and water can promote zinc corrosion. Cleaning always reduces value and is irreversible. For valuable coins with specific problems, professional conservation through grading services is available, but home cleaning attempts should never be undertaken.
Why are Red (RD) coins worth so much more than Brown (BN)?
Color preservation is a primary value driver for copper-plated cents. Red (RD) designation requires 85%+ retention of original mint luster and indicates the coin has been exceptionally well-preserved with minimal oxidation. Brown (BN) indicates heavy oxidation from environmental exposure. The color differential can create 300%+ premiums at the same numeric grade—for example, a 1998 Wide AM in MS-65 BN is worth $27, while MS-65 RD is worth $85. The zinc core's instability makes achieving and maintaining Red color difficult, creating conditional rarity that drives premiums.
What is the rarest 1998 penny?
The rarest 1998 penny is the 1998-S Close AM proof (FS-901), with only 9 examples graded PR-70 DCAM by PCGS as of late 2024. This variety was created when a business strike reverse die was accidentally paired with a proof obverse, and it commands up to $5,160 in perfect condition. The 1998-P Wide AM business strike is more common (estimated 100,000+ exist) but still scarce, reaching $6,000 in MS-68 RD. Major error coins, such as 1998 cents struck on dime planchets, are also rare and valuable ($1,000-$3,500).
Are there any valuable doubled die varieties for 1998 pennies?
Yes, but they are minor specialist varieties with modest value. Multiple Doubled Die Reverse (DDR) varieties are cataloged for 1998-P and 1998-D by CONECA and Variety Vista, typically showing minor doubling on Memorial columns. Examples include 1998-D DDR-001 and 1998-D WDDR-002. These varieties are not attributed by major grading services (PCGS/NGC) and trade in the specialist market for $5-$30 in uncirculated condition. They require magnification and reference photos for identification and are primarily collected by die variety specialists rather than general Lincoln Cent collectors.
How do I tell if my 1998-S proof is the rare Close AM variety?
Examine the reverse under magnification and look for Close AM spacing where the A and M in "AMERICA" nearly touch—this is abnormal for 1998-S proofs, which should have Wide AM spacing. Confirm with the FG initials: the rare Close AM proof has a non-flared "G" positioned further from the Memorial base, while the common Wide AM proof has a flared "G" closer to the base. Because counterfeits exist, any suspected Close AM proof should be authenticated by PCGS or NGC before assuming value, as this variety is worth $180-$5,160 versus $5-$70 for the common proof.
Research Methodology and Sources
This valuation guide synthesizes data from multiple authoritative numismatic sources to provide accurate, current market values for 1998 Lincoln Cents. Primary price data derives from PCGS CoinFacts Price Guide and NGC Coin Explorer, representing the two major third-party grading services whose population reports and pricing information establish industry standards. These sources were accessed in November 2025 to ensure current market values (PCGS CoinFacts)(NGC Coin Explorer).
Variety identification diagnostics and authentication guidance are based on recognized attribution systems including Fivaz-Stanton (FS), CONECA, and Variety Vista catalogs (Error-Ref.com)(Variety Vista). Auction records from Heritage Auctions provide verification of realized prices for key varieties and high-grade examples (Heritage Auctions).
Technical specifications including weight, diameter, composition, and mintage figures are sourced from U.S. Mint records as compiled in numismatic references. Where discrepancies exist between sources (such as the 30-million variance in 1998-D mintage between PCGS and NGC), both figures are noted with appropriate citations.
Market values represent retail pricing for certified coins in holders from major grading services. Raw (uncertified) coins typically trade at 30-50% discounts. Prices fluctuate based on market conditions, and actual realized prices may vary from stated values depending on eye appeal, market timing, and venue (auction vs dealer vs private sale). This guide should be used as a reference tool; buyers and sellers should verify current market conditions before transactions.
