Details
GMA is known as an economy grading option that provides basic authentication and grading services at lower price points. While GMA-graded cards typically don't command the same premiums as PSA or BGS, they offer an affordable way for collectors to protect and authenticate their cards. GMA uses a 10-point grading scale.
