What this classification means
The 1982 cent transition created multiple date, mint, and composition combinations that require both visual subtype and weight. A useful identification does more than name an unusual shape. It explains when in production the feature formed, what physical evidence should remain, and which ordinary forms of damage can imitate it.
Diagnostic evidence to record
Calibrate a 0.01-gram scale, confirm date size, mintmark, surface, and repeated measurements.
- Compare with certified examples and mint-production references, not viral price claims.
Common lookalikes and failure points
Dirty coins, scale drift, plated pieces, and confusing large-date with small-date types cause errors.
A practical examination sequence
- Confirm the host coin. Identify denomination, design subtype, date, mint, composition, and expected weight.
- Describe before naming. Write what the metal actually does without using a marketplace label.
Value factors
Use United States Mint production references to understand how blanks, planchets, dies, collars, and presses work. Use major grading-service references to compare diagnostic language. Treat marketplace descriptions as leads to investigate.
