Assay

Caution2Context1

Each stamp is one fixed formula applied identically to every card. Supportive and caution mark a reading that cuts the same way for anyone holding the card. Context marks a fact that is good news to a buyer and bad news to a holder, so the desk does not pick a side.

LiquidityCaution

FROZEN

Verified sales a week at PSA 10, from the daily graded tape.

Registry inflowContext

EFFECTIVELY CLOSED

New slabs a week against the recorded PSA population.

Character demandCaution

NICHE CHARACTER

The species demand index, a weighted percentile across every tracked species.

Every verdict is a disclosed formula over recorded data, applied with the same fixed thresholds to every card. No discretionary price forecasting is used, and the arithmetic is printed so it can be reproduced.
