The Lincoln penny has been an American icon for over a century, and modern Lincoln cents continue to captivate collectors worldwide. Whether you’re examining Memorial cents from your pocket change, hunting for pristine Shield pennies, or cherishing the special 2009 Bicentennial designs, understanding how to grade these coins properly is essential for any collector.

Since 1959, the Lincoln cent has undergone three major design changes, each bringing unique characteristics that affect grading. This guide will walk you through the process of evaluating modern Lincoln pennies, helping you determine their condition and value with confidence.

History of Modern Lincoln Pennies

The modern era of Lincoln cents began in 1959 when the familiar wheat ears reverse gave way to the Lincoln Memorial design. This marked the 150th anniversary of Lincoln’s birth and the 50th anniversary of the Lincoln cent itself.

Three distinct periods define modern Lincoln pennies:

Memorial Cents (1959-2008): Featured the Lincoln Memorial on the reverse
Bicentennial Cents (2009): Four special reverses celebrating Lincoln’s life
Shield Cents (2010-present): Display the Union Shield, symbolizing Lincoln’s preservation of the United States

Modern Lincoln Penny Grading Standards

Before diving into specific grades, it’s important to understand that coin grading combines both art and science. While the Sheldon Scale provides a numerical framework from 1 to 70, assigning grades requires careful observation and experience.

Professional grading services like PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Corporation) employ teams of experts who evaluate thousands of coins daily. However, learning to grade coins yourself not only saves money but also sharpens your eye as a collector.

Essential Grading Tools

To grade Lincoln pennies effectively, you’ll need:

A 5x to 10x magnifying loupe or jeweler’s loop
Good lighting (preferably incandescent or LED)
A soft surface to handle coins
Reference guides with photographic examples
Clean cotton gloves to avoid fingerprints

Special Considerations for Modern Pennies

Color Designations

Like their Wheat penny predecessors, modern Lincoln cents receive color designations:

RD (Red): Full original mint luster, most desirable
RB (Red-Brown): Partial red luster mixed with brown toning
BN (Brown): Predominantly brown, least valuable for same grade

Zinc Rot and Corrosion

Post-1982 zinc pennies present unique challenges. The thin copper plating can be breached, allowing moisture to corrode the zinc core. This “zinc rot” appears as white, powdery spots or bubbling under the surface. Unfortunately, this damage is irreversible and significantly impacts value.

How to Modern Lincoln Penny

Let’s examine each grade level, from the most worn to pristine mint state examples. Remember, grading requires examining both the obverse (front) and reverse (back) of the coin.

1. Poor (P-1)

These coins are barely identifiable as Lincoln cents. The date might be partially visible, but most design elements have worn smooth.

Obverse: Lincoln’s silhouette is faintly visible. The rim merges with the field in many areas. Date and lettering are mostly gone.

Reverse: Design type (Memorial, Shield, etc.) is barely recognizable. Most details are completely worn away.

2. Fair (FR-2)

Slightly better than Poor, but still heavily worn. The coin type is identifiable, though details remain minimal.

Obverse: Lincoln’s outline is clear, but facial features are gone. Some letters might be partially visible. The date, though worn, can usually be determined.

Reverse: The basic design shape is visible, but fine details are absent. On Memorial cents, you might see the building’s outline; on Shield cents, just the shield’s basic form.

3. About Good (AG-3)

These pennies show heavy wear but retain more recognizable features than lower grades.

Obverse: Lincoln’s head is outlined but flat. Most of the lettering is readable though weak. The date is fully visible but may blend with the rim.

Reverse:

Memorial: Building outline is complete but lacks interior details
Shield: Basic shield design visible but stripes merge together
Lettering is mostly readable but weak

4. Good (G-4, G-6)

Coins in Good condition show significant wear but maintain the main design elements.

Obverse: Lincoln’s portrait is well-worn but complete. Hair above the ear is flat, and facial features merge. Letters and date are clear but may show weakness.

Reverse:

Memorial: Columns are visible but worn, steps might be faintly outlined
Shield: Individual stripes begin to show separation
All lettering is complete and readable

5. Very Good (VG-8, VG-10)

Major design elements are clear despite moderate to heavy wear.

Obverse: Hair details begin to show, particularly at the back of Lincoln’s head. The bow tie is visible. Ear shows basic outline. Letters are bold and clear.

Reverse:

Memorial: Some column details visible, steps show separation
Shield: Most stripes are distinct, though worn at high points
E PLURIBUS UNUM may show slight weakness

6. Fine (F-12, F-15)

Moderate, even wear characterizes Fine grade pennies.

Obverse: About half of Lincoln’s hair details are visible. The ear shows interior detail. Bow tie is complete. Cheek and jaw remain smooth but well-defined.

Reverse:

Memorial: All columns show some detail, most steps are separated
Shield: All 13 stripes are distinct with visible horizontal lines
All lettering is sharp and clear

7. Very Fine (VF-20, VF-25, VF-30, VF-35)

Light to moderate wear appears only on the highest points.

Obverse: Most hair details are sharp, including strands above the ear. Fine lines in the bow tie are visible. The ear shows clear inner and outer detail.

Reverse:

Memorial: Column details are sharp, individual steps clearly separated
Shield: Horizontal lines within stripes are clear, scroll ends show detail
Minor wear on highest points only

8. Extremely Fine (EF-40, EF-45)

Very light wear limited to the highest design points.

Obverse: All hair details are sharp and clear. Only slight wear shows on Lincoln’s cheek and jaw. The coat shows texture and buttons are detailed.

Reverse:

Memorial: Slight wear on column tops and center steps only
Shield: Light wear on top horizontal lines of shield
Nearly full mint luster may remain in protected areas

9. About Uncirculated (AU-50, AU-53, AU-55, AU-58)

Trace wear visible only under magnification, with substantial mint luster remaining.

Obverse: Faint wear on cheek, jaw, and hair above ear. All details remain sharp. Luster is present but may be broken on high points.

Reverse:

Memorial: Trace wear on building’s highest points
Shield: Slight wear on top scroll and upper shield lines only
AU-58 shows virtually full luster with minimal wear traces

10. Mint State (MS-60 to MS-70)

Uncirculated coins with no wear, graded by strike quality, luster, and eye appeal.

MS-60 to MS-63: May have numerous contact marks, spots, or weak strike areas. Luster may be impaired but coin shows no circulation wear.

MS-64 to MS-66: Fewer marks, better strike, and attractive luster. MS-65 is considered “gem” quality with strong eye appeal.

MS-67 to MS-70: Superior quality with minimal to no visible flaws. MS-70 is perfection – extremely rare for business strikes.

Design-Specific Grading Points

Memorial Reverse Focus Areas

Columns: Check for definition in the fluting
Steps: Count visible lines between columns
Roof: Look for triangular detail sharpness

Shield Reverse Focus Areas

Horizontal lines: Should be distinct within each stripe
Scroll: Check ends for complete detail
E PLURIBUS UNUM: Should be sharp and raised

Common Grading Challenges

Weak Strike vs. Wear

Some pennies, particularly from certain years and mints, show weak strikes that can be mistaken for wear. A weakly struck MS-65 might show less detail than a well-struck EF-45. Look for mint luster and contact marks rather than relying solely on detail.

Cleaned Coins

Harsh cleaning leaves pennies with an unnatural appearance – too bright, with hairlines or a “stripped” look. These are considered damaged and trade at significant discounts.

Environmental Damage

Besides zinc rot on modern cents, watch for:

Corrosion spots (green or black)
PVC damage from improper storage
Fingerprints etched into the surface

Market Values and Grade Importance

While common date modern pennies in circulated grades hold minimal premium, certain dates and varieties command significant prices in high grades:

1969-S Doubled Die Obverse
1972 Doubled Die Obverse
1983 Doubled Die Reverse
1984 Doubled Ear
1992-D Close AM
1995 Doubled Die Obverse

In MS-67 or higher, even common dates can be valuable due to the difficulty in finding pristine examples.

Building Your Grading Skills

Becoming proficient at grading takes practice and patience. Here are some tips:

Start with circulated coins: They’re cheaper and easier to distinguish between grades
Compare with certified examples: Study slabbed coins at coin shows
Use multiple sources: Different lighting angles reveal different details
Join a coin club: Learn from experienced collectors
Practice consistently: Grade the same coin multiple times over weeks

When to Use Professional Grading

Consider professional grading for:

Key dates and varieties
Coins you believe grade MS-65 or higher
Any coin worth over $100
Coins you plan to sell

Summary

Grading modern Lincoln pennies requires understanding the nuances of each design type, recognizing how wear patterns develop, and distinguishing between various surface conditions. While the Sheldon Scale provides a framework, remember that grading is subjective – two experts might disagree by a point or two.

Start with inexpensive examples and gradually work your way up to better coins. With practice, you’ll develop the confidence to accurately assess condition and make informed decisions about your collection. Whether you’re searching rolls for varieties or building a high-grade set, understanding grading fundamentals enhances both your enjoyment and success in the hobby.

Remember, every expert was once a beginner. Take your time, ask questions, and most importantly, have fun exploring the fascinating world of modern Lincoln cent collecting!
