Configuration before comparison.
Read the guide“Serial number matches, so it's real.”
False. Counterfeit items can copy valid-looking numbers. Treat numbers as one evidence point, not proof.
Unknown ≠ fake
PieceID separates a confirmed inconsistency from insufficient data. Missing evidence should never be turned into a fake verdict.
High-value purchase?
Use visual screening to decide what to inspect next, then escalate to qualified physical authentication when the stakes justify it.
Start with the question, not a verdict.
For each detail, record the seller’s claim, the source used for comparison and the limits of the photograph. Two matching details from the same copied document are not independent evidence.
What is physically visible?
Describe the construction, material, markings and configuration without interpreting them first.
What would change the decision?
Request the missing angle, identify the claimed period and escalate high-stakes uncertainty to a qualified specialist.
