Understanding coin grades (MS, PF, etc.)
A guide to numismatic grading scales.
Coin grading uses a 1-70 scale developed by Dr. William Sheldon.
**Grade Prefixes:**
- MS (Mint State): Uncirculated coins
- PF/PR (Proof): Special collector strikes
- AU (About Uncirculated): 50-58
- XF/EF (Extremely Fine): 40-45
- VF (Very Fine): 20-35
- F (Fine): 12-15
- VG (Very Good): 8-10
- G (Good): 4-6
**Common Grades:**
- MS70/PF70: Perfect, no flaws under 5x magnification
- MS69/PF69: Near perfect, tiny imperfections
- MS67-68: Superb gem quality
- MS65-66: Gem quality
- MS63-64: Choice uncirculated
- MS60-62: Uncirculated with visible marks
**Designations:**
- CAM: Cameo (light frost on devices)
- DCAM/UCAM: Deep/Ultra Cameo (heavy frost)
- +: Plus grades (above average for grade)
- ★: Star designation (exceptional eye appeal)
Price Impact: Each grade point can significantly affect value. An MS67 might be worth 2-3x an MS66.
