GSI has created an easy way for you to verify that the information you have on your GSI grading report reflects the data we maintain in our lab. This is an important security feature in the event that you lose your grading report or question its authenticity.

Simply key in below your Grading Report Number (It's a good idea to record this number in a place you can easily access it in the event of report loss.)
