About Us

In 2010, we felt that something was missing in the world of sports cards grading.

International Sports Authentication has over twenty years experience working full-time in the sports cards industry, and has been grading cards on a daily basis for those same two decades. Our founder is one of the hobby’s foremost experts in the field of card grading, because he loves sports and collectibles and has devoted his life to the industry: “Every day is exciting because you never know what historic collectible may come into the office.”

ISA is proud of its user-friendly website and freely welcomes customer input and questions.
