GMA Grading (Grading & Authentication)

GMA Sports Card Grading

Last of the recognized and Top Sports Card Grading Companies in the hobby, GMA Grading is lesser known or at the quality level of the other three (BGS, PSA or SGC). Despite being lower tier, GMA offers solid sports card grading service at a lower-price and faster turnaround since the sports card grading boom in 2021.

Characteristics of Sports Card Grading

Characteristics of sports card grading consists of the corners, centering, surfaces, edges as well as quality of autograph (if card is autographed). For the most part the four key characteristics directly impact how the third-party grading services will grade the card in terms of their sports card grading scale. On cards graded by Beckett Grading Services, a physical grade will be displayed on the encapsulated case for each of the following Corners, Centering, Surfaces and Edges, as well as an overall grade of the card (and autograph if the card has an autograph).

Meanwhile, PSA and SGC, do not display individual grades for characteristic on the card but value it into their overall grade.


When it comes to “Corners” it is talking about the four corners on most cards as well as additional corners on Die-Cut cards. A perfectly sharp corner is required to land a perfect score or a Gem MT rating. Sports card grading services use high-definition magnification tools to examine each corner from both the front and back of the card. Any ding, imperfection or what looks to not be a perfect sharp corner will see a reduction in grading. Rounded corners and bent corners will result in either fair or poor sports card grades.


Sports card centering means that the actual border of the card on all four sides measure the same from the edge of the border to the edge of the sports card. If the card does not have the same margin on all four sides, the card will be graded lower depending on the actual grading company. Off-Center cards or cards that land an OC qualifier will have lower grades.


One sports card grading characteristic that gets overlooked is the actual surface of the card. However, this is a key component that is inspected by any of the top grading companies. Issues on surfaces that can impact grades could include debris or dirt that is in the card during printing, fingerprints (chrome, metallic and refractor cards mostly), as well as any scratches or flaws that might be present.


Edges of the card are the outside border of the sports card that connects to each corner. Much like the corners, edges are examined for potential dings, chips or separation within the cardboard that is applied together.

Sports Card Grading Scales

Sports Card Grading grades are the definitive collaborated score assigned by the designated grading company for that specific card based on the characteristics. While these grades vary based on companies, not all sports card grading companies are the same and not all sports card grading experts have the same grading scale. Based on this, each Sports Card Grading Grades vary based on the company. Here are the sports card grading scales for each of the top grading companies:

Beckett also uses other labels to go along with the black label, such as a gold label for cards 9.5 or 10 (Vintage), as well as silver labels for graded cards ranging from an 8.5 to 9 and a white label for cards grading below an 8.5.

PSA Gem Mint 10                             $404

PSA Mint 9.                                      $167.50
