Card grading is the process of sending a trading card to a professional company that authenticates it, judges its condition, and assigns a number on a 1 to 10 scale. The card comes back sealed in a tamper-evident plastic slab with a unique certification number you can look up online. That number becomes a shared, trusted shorthand for how sharp the card is, which is why a graded card usually sells for more than the same card raw.
What do graders actually check?
Graders check four physical factors: centering, corners, edges, and surface. They also confirm the card is genuine and not trimmed or restored before any grade is assigned. Each factor is weighed under bright, controlled light and often under magnification, so a card can ace three factors and still land a lower number if the fourth drags it down.
| Factor | What graders look for |
|---|---|
| Centering | How evenly the border frames the art on front and back, measured as a left-to-right and top-to-bottom ratio |
| Corners | Sharpness of all four points, checked for fraying, softness, or tiny white dings |
| Edges | Smoothness along every side, checked for chipping, nicks, and whitening |
| Surface | Gloss and cleanliness of the card face, checked for scratches, print lines, dents, and scuffs |
How does the submission process work?
You pick a service level, pack the card safely, and mail it to the grading company. They log it in, grade it, slab it, and ship it back, then post the result to their online database under your cert number.
- 1Create an account with a grading company and choose a service tier based on the card's value and how fast you want it back.
- 2Fill out the submission form, listing each card and its declared value, which sets your per-card fee and insurance.
- 3Protect each card in a penny sleeve and semi-rigid holder, then pack it snugly so nothing shifts in transit.
- 4Ship the package with tracking and insurance to the address on your submission.
- 5Wait through the queue as the card is received, authenticated, graded, and slabbed.
- 6Verify the grade and cert number against the company's online lookup when the sealed slab arrives.
Grade the card, then look up its cert number online. A legitimate slab always ties to a public record you can confirm, which is your best defense against fakes and reslabs.
How long does grading take?
Turnaround depends entirely on the service tier you pay for. Faster tiers cost more and can return in days to a couple of weeks, while cheaper economy tiers can run many weeks or longer when submission volume spikes.
Two things push wait times up: the value tier you choose and the overall backlog at the company. Big product releases and holiday surges flood the queues, so the same economy tier that felt quick in a slow month can crawl during a busy one. If you need a card back by a specific date, pay up for a faster tier rather than gambling on the economy line.

Grading is only worth it when the card is worth protecting, and that depends on what the market is paying right now. Set a price watch on GrailHawk for the cards you are eyeing, so you know a card's raw value before you ever pay to slab it.
