Interactive triage
Error or damage?
Answer evidence questions before choosing a label. The result is a research priority, not authentication.
What the tool cannot do
It cannot authenticate a coin, determine composition from color, assign a die variety from a vague description, or calculate value.
Strong evidence
- Calibrated weight and measurements
- Full edge documentation
- Metal flow and strike relationships
- Repeatable die markers
- Certified matching examples
Weak evidence
- A seller’s asking price
- A viral nickname
- One extreme-magnification photo
- “I have never seen one like it”
- Color alone
