Authentication and Grading Services

Global Authority’s three core business divisions are card grading, wax and unopened collectible grading and our Global Passport™ segment providing unique ways to help maximize the value of a collectible. These three service areas of our business form the basis of what we offer. We have added innovative ways to escalate the user functionality of our Web site and the visibility of our company brand. We continue to focus on research and development, creating innovative products and services complementing our existing user options.
