What is a PSA centering tool?
A PSA centering tool is a device or app that measures card centering according to PSA's grading standards for trading cards.
PSA centering tools help collectors assess whether their cards meet the centering requirements for a given PSA grade. These tools provide centering ratios or percentages, allowing users to pre-screen cards before submission. Midpoint can calculate centering based on PSA's grading guidelines.
