Grading Standards

We use KSA in Elmira, Ontario for our grading service.  The company has been in business since 1996.

KSA uses a 10-point certification process that includes checking centering, corners, cut, colour, borders, enamel, focus, picture quality, registration and micro imperfections. Cards are measured, checked under magnification and special lighting.
