Tips for Beginner Graders

Use Good Lighting

Natural daylight or 75-watt incandescent bulb at 45-degree angle reveals wear patterns best.

Magnify Carefully

Use 5x-10x magnifier. Higher magnification can exaggerate minor flaws.

Practice Often

Start with common coins. Compare your grades with certified slabs to improve accuracy.
