PSA Grading
Professional Sports Authenticator grading service for trading cards. Cards are submitted to PSA, which authenticates and grades them on a scale from 1 (Poor) to 10 (Gem Mint). PSA-graded cards sell for 3–10x the price of equivalent raw (ungraded) cards at grades 9 and 10. The service costs AU$30–70+ per card depending on turnaround tier. Worthwhile for valuable cards; not economical for commons.
