Penny Grading Guide
Learn how to evaluate and grade your penny collection
Coin grading is the process of determining a coin's condition and assigning it a grade that reflects its state of preservation. The grade directly affects a coin's value - higher grades typically command significantly higher prices.
There are two main approaches to grading: professional grading by certified services and estimated grading by collectors. Both have their place in numismatics.
The Grading Scale
Coins that have never been in circulation. No wear on the highest points. MS-70 is perfect, while MS-60 shows bag marks and contact marks but no wear.
Look for: Full mint luster, sharp details, no wear on high points
Value multiplier: 100% (Mint condition)
Slight wear on the highest points. Most of the original mint luster remains. Often appears uncirculated at first glance.
Look for: Traces of wear on highest points, 50%+ mint luster
Value multiplier: ~75% (Near Mint condition)
Moderate to considerable even wear. All major design elements are clear. Lincoln's hair shows considerable wear but individual strands are visible.
Look for: Even wear, all lettering clear, major details visible
Value multiplier: ~50% (Fine condition)
Heavily worn with major design elements visible but faint. Date and mint mark are readable. Rim is complete and raised.
Look for: Heavy wear, date readable, rim intact
Value multiplier: ~30% (Good condition)
Extremely worn. Date may be barely visible. Coin is identifiable but shows extreme wear. Still collectible for rare dates.
Look for: Extreme wear, date may be weak, still identifiable
Value multiplier: ~10% (Poor condition)
Visual Examples
Compare your coins to these examples to help determine their grade. Notice the progression of wear from pristine mint condition to heavily circulated.

Key Areas to Examine on Lincoln Pennies:
- • Lincoln's cheekbone - First place to show wear
- • Lincoln's hair detail - Individual strands visible in higher grades
- • Wheat stalks (1909-1958) - Lines should be distinct
- • Memorial pillars (1959-2008) - Steps should be clear
- • Shield lines (2010+) - Vertical lines should be sharp
- • Date and mint mark - Should be fully legible
Pro Tip:
Use a 10x magnifying glass and good lighting. Compare your coin to graded examples online. When in doubt, grade conservatively - it's better to underestimate than overestimate.
