Card Grading Explained: PSA, BGS and CGC Basics

Card grading is paying a company roughly $15-30 to authenticate your card, score its condition from 1 to 10, and seal it in a tamper-evident plastic slab. That's the whole product. Whether it's worth it comes down to one question: does the graded price minus the fee beat the raw price? Often it doesn't.

What grading actually does

Three things, in order of real-world importance:

  1. Authentication. The grader confirms the card is genuine. For high-value vintage — where fakes cluster — this alone can justify the fee, because buyers pay more for certainty. If you're buying raw vintage, read how to spot fake Pokémon cards first.
  2. Condition scoring. A trained grader assigns a numeric grade. This converts "trust me, it's mint" into a number the whole market accepts.
  3. Protection and liquidity. The slab protects the card and makes it instantly sellable at a known price point. A PSA 10 of a popular card is one of the most liquid objects in the hobby.

The 1-10 scale

All three major graders use a 10-point scale, with half grades in between. The market only really cares about the top of it.

  • 10 (Gem Mint): Near-perfect. This is where the money is — the 10-vs-9 price gap is often the entire economic case for grading.
  • 9 (Mint): One tiny flaw. Frequently sells near, or even below, the raw NM price once fees are counted.
  • 8 (NM-Mint): Visible minor wear. For modern cards, an 8 usually means you lost money grading.
  • 7 and below: Only worth slabbing for expensive vintage, where a mid-grade Base Set holo still carries real value.

Each grader adds its own twist: BGS awards four subgrades and a "Black Label" 10 (all four subgrades perfect), CGC has a "Pristine 10" above its Gem Mint 10, and PSA keeps it simple with one number. The differences between the companies matter enough that we wrote a separate PSA vs BGS vs CGC comparison.

The four things graders check

Every grader scores the same four attributes:

  • Centering. The ratio of the borders. PSA allows roughly 60/40 on the front for a 10; BGS wants closer to 55/45 or better. This is the easiest attribute to check yourself — see our card centering guide — and the most common reason modern Pokémon cards miss a 10.
  • Corners. Sharpness under magnification. Whitening on a single corner can be the difference between 10 and 9.
  • Edges. Chipping and whitening along the cut, especially visible on dark-bordered cards.
  • Surface. Scratches, print lines, holo scuffs, dents, clouding. The sneakiest category, because surface flaws often only show under angled light.

A card fresh from a pack can fail any of these. Factory handling is rougher than most people assume — packs contain cards that were printed, cut and shoved through rollers at industrial speed.

What it costs and how long it takes

Ballpark figures as of mid-2026, for standard-value cards:

  • PSA: cheapest tiers run about $17-25 per card, often with bulk minimums, and turnaround measured in weeks to a couple of months. Prices climb steeply for higher-value cards.
  • BGS: base service around $20-27, similar waits, subgrades sometimes extra.
  • CGC: the value play at roughly $12-18 for bulk tiers, with typically faster turnaround.

Add shipping both ways with insurance — call it $15-30 spread across a submission — and a realistic all-in cost of $20-35 per card. That number is the hurdle every grading decision has to clear.

When grading makes sense

Grade when at least one of these is true:

  • The 10 premium is large. If the PSA 10 sells for $60-70+ more than the raw copy, screened cards have positive expected value. The full break-even math lives in should you grade modern Pokémon cards.
  • It's valuable vintage. Authentication plus protection plus liquidity is a strong bundle for a card worth hundreds raw, almost regardless of grade.
  • You're keeping it forever. A slab is excellent long-term protection. Paying $25 to armor a personal grail is a defensible consumer choice, not an investment.

Skip grading when the card is worth under about $50 raw, when the centering is visibly off, or when you'd be grading purely because the card is shiny and new. Most modern cards out of most packs — and the Pack Value Calculator will show you exactly what those pulls are worth raw — don't clear the fee hurdle.

FAQ

How much does card grading cost in total?

Budget $20-35 per card all-in: the grading fee plus insured shipping both directions. Bulk submissions at CGC land at the bottom of that range, PSA higher-value tiers well above it.

What grade do most cards get?

Most well-kept modern cards land at 8-9. Gem Mint 10s are the minority even for cards straight out of a pack, mainly due to centering and factory surface flaws.

Does grading always increase a card's value?

No. A 9 or below on a modern card frequently sells for less than the raw price plus fees. Grading adds value only when the achieved grade carries a premium bigger than the cost.
