Grademaster Card Grading/Centering Tool

This tool can be used with the proprietary centering calculator sheet to decide whether you should send your trading/sports/role playing cards (standard 2.5 x 3.5 inch, includes Pokemon) in to the third party grading companies to bump your collectible's value up.
So easy to use, just center the card under the clear, graduated template, read off the numbers for the worst centering from either top to bottom, or side to side; and look on the calculator sheet to estimate your card's centering.
Because third party grading is extremely subjective, no tool will always measure exactly as the grader does, but through extensive testing, this tool has been proven to be very close 100% of the time and always conservative to actually measuring with a ruler.
