What to watch

Reviewers repeatedly flag the absence of an accessible population or certification lookup, which removes the verification step buyers rely on, and there are unsubstantiated claims circulating about slab integrity.

All known concerns

The cheapest grading available anywhere, and the price is the entire proposition. Economy falls to $9 a card above 100, which nothing else approaches.

Prices as checked on 9 Oct 2026. They change often; the grader's own list is the final word.

The catch is that you cannot try it small — every tier carries a minimum, from 10 cards on Gold Express to 25 on Economy, so the cheapest rate needs a 100-card pile. Worth weighing against the resale reality: buyers do not pay a premium for a GMA slab.

The full file

What sets them apart

The cheapest grading available anywhere, at $9 a card in volume, with a claimed seven-day turnaround. That price is the entire proposition — there is no technology story, no subgrade report and no registry.

Where the slab sells

GMA is the clearest example of listing not equalling standing: buyers can find the slabs easily and still discount them.

eBay

Listed in eBay's professional grader filter, so GMA slabs are searchable, but GMA is not covered by the Authenticity Guarantee and receives no eBay buyer protection.

Auction houses

Not standard inventory at Goldin, Heritage or PWCC.

Card shops and general resale

Widely recognized by name because of its volume and low price, but recognized as a budget option rather than a value-preserving one.

Hobby guidance routinely advises against GMA for cards with real resale value.

Turnaround

10 days on Gold Express

The slab and the label

Subgrades: None

An ordinary clear holder with a black inner surround.

Label, front
Close view of the front label on a GMA Grading & Authentication slab
Label, back
Close view of the back label on a GMA Grading & Authentication slab

Example slab shown for reference, not a card the editor owns.

A black-and-gold label with the card description and a cert number, and no subgrades. There is no public lookup to check that number against, which leaves the label asserting something a buyer cannot confirm.

What they grade

  • Sports Cards
  • TCG
  • Non-Sports & Entertainment

Who it's for

  • Personal Collection
  • Protection & Preservation
  • Authentication

Bulk protection and personal collections. The cheapest legitimate way to get a card into a holder.

Known concerns

Reviewers repeatedly flag the absence of an accessible population or certification lookup, which removes the verification step buyers rely on, and there are unsubstantiated claims circulating about slab integrity.

Hobby guidance consistently advises against GMA for cards with meaningful value. Reasonable for bulk, poor for anything you intend to sell.

History

GMA Grading has operated since 2003, competing almost entirely on price. Its rates sit among the lowest in the industry and it has historically turned submissions around quickly.

That combination made it a common choice for bulk submissions and low-value cards, where grading with a major would cost more than the card is worth.

It has not built the infrastructure the majors have — reviewers note the absence of an easily accessible online population or certification database.

Score breakdown

Five parts, each scored 0 to 100 and weighted. Market acceptance carries 60 of the 100, because the point of a slab is what the market pays for it.
