How We Calculate Grading Profit

Modeled expected net profit combines available grade prices with historical population shares, then subtracts the raw buy price, grading cost and selected selling fees. Conditional PSA 10 profit assumes the highest grade and is a different measure. Neither predicts your card's grade or guarantees a sale. Inspect condition and exact sold comparisons, and include costs that the model does not cover. See the full methodology.
