The Sheldon Scale Explained

Coin grading from Poor-1 to Mint State-70. The 70-point system every numismatist, dealer, and grading service uses. Learn what to look for before you buy.

Why grading matters: The difference between an MS-64 Morgan dollar and an MS-65 can be hundreds of dollars. The difference between MS-65 and MS-67 can be thousands. A coin's grade is determined by wear, strike quality, surface preservation, luster, and eye appeal. Below is the canonical Sheldon Scale, devised by Dr. William Sheldon in 1949 and still the industry standard at PCGS, NGC, and ANACS.

Field Notes for the Stacker-Turned-Collector

Always grade in raw natural light or 5500K LED — yellow incandescent hides hairlines and cleaning damage.
Use a 5x to 10x loupe. Higher magnification (20x+) is for authenticators looking at die markers, not graders.
Tilt the coin under the light. Original cartwheel luster on uncirculated coins rotates as you rotate the coin. Cleaned coins show flat, dull surfaces or unnatural shine.
"Details" graded coins (cleaned, scratched, environmental damage) are worth a fraction of straight-graded equivalents. PCGS/NGC genuine holders identify the problem.
For bullion-grade silver and gold, MS-60 vs MS-65 rarely matters — melt value rules. For pre-1933 US gold and key-date Morgans, grade is everything.
Eye appeal can bump a coin a full grade. A toned MS-64 Morgan with rainbow color outsells a blast-white MS-65.
