A clear learning path for new collectors and a useful reference desk for experienced hunters.

Core skills

1. Identify the date, mint mark, denomination, and design type.
2. Distinguish mint errors, die varieties, machine doubling, and post-mint damage.
3. Use magnification, good lighting, a scale, and clear photographs.
4. Compare findings with documented references before making a value claim.
