Complete guide for coin grading basics — step-by-step workflow, tools, checklist, and expert tips to get started.
Study AG-3 through MS-70 definitions focusing on wear points: hair detail on portraits, rim nicks, and field scratches.
Under a single 75W incandescent bulb, assess cartwheel luster, weakness at centers, and overall eye appeal modifiers.
Match your coins to published grade photos and PCGS/NGC photograde images before assigning a numeric grade.
Estimate grades on ten raw coins, then compare to dealer opinions or submission results to calibrate your eye.
Record grade estimates with written justification for wear points, luster, and strike on each practice coin.
Calculate wear percentage on high-relief design elements to distinguish AU from MS grades.
Apply structured grading criteria similar to inclusion scoring when evaluating surface marks and eye appeal.
Capture consistent lighting photos for side-by-side comparison with photograde references.
Key design elements lost at common circulated grades.
| Grade | Liberty Cap Detail | Reverse Eagle |
|---|---|---|
| VF-20 | Hair lines visible | Most feather detail |
| EF-40 | Hair well defined | Full feather separation |
| AU-50 | Slight rub on cheek | Full mint luster mostly intact |
| MS-63 | No wear | Full luster, visible bag marks |
Photos lie — always grade raw coins in hand under consistent lighting.
Known weak-strike issues like 1926-D nickel demand strike allowance — not wear downgrade.
Cleaning destroys value — a dipped MS coin becomes net damaged regardless of appearance.
