Our reading

Context1

Each verdict 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 we do not pick a side.

New PSA copiesContext

Almost no new PSA copies

New PSA-graded copies a week, against the number PSA has graded so far.

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.
