PSA grading estimates require careful evaluation of four key factors: centering, corners, edges, and surface condition. Use our calculator above to input your card's condition across these categories and get an instant grade prediction.
Professional graders examine cards under magnification to identify imperfections invisible to the naked eye. A PSA 10 (Gem Mint) requires near-perfect centering (55/45 or better), sharp corners with no wear, pristine edges, and a flawless surface free of scratches or print lines.
For accurate PSA grading estimates, inspect your card under bright light and compare against PSA's official grading standards. Our ROI calculator factors in grading fees, shipping costs, and current market values to show whether professional grading will increase your card's value.
