PSA 10 copies trade more often than 90% of the JA era.
Reference class: JA era. Percentiles are recomputed nightly, by disclosed rule, from recorded data across every tracked card.
What the fixed formulas say about the figures below, with the arithmetic shown.
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.
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.
Pro breaks the seal on our call: a stamped buy, hold, or sell and a 180-day target price on every rated card, each a disclosed formula over recorded data. Below is every section this dossier is holding back.
