Pre-Grading a Raw Card

Estimate the grade before PSA does, then decide if the slab is worth the fee.

CardVault stores let customers buy, sell, trade, and grade cards.[1] So the question you'll hear constantly is: "Should I send this in?" A good answer has two halves. First, a realistic grade range from looking at the card. Second, the math: does the likely graded value beat the raw value plus the fees?

What the grader looks at

PSA grades on a 1–10 scale and judges four things.[2] Check them in this order, because centering is the only one you can measure with a ruler.

1 · CENTERING

How even the borders are, left/right and top/bottom, on the front and back. Written as a ratio like 60/40.

2 · CORNERS

A PSA 10 needs four perfectly sharp corners. "The slightest fraying at one or two corners" is already PSA 8 territory.[2]

3 · EDGES

Look for white chipping along the colored border, which shows up badly on dark-bordered chrome cards.

4 · SURFACE

Tilt the card under a light: scratches, print lines, dimples, stains, lost gloss. A 10 needs full original gloss.[2]

The weakest-link rule

PSA's grade definitions read as ceilings. A Mint 9 is allowed only one minor flaw.[2] Perfect centering can't rescue a soft corner. Your estimate is the lowest of the four, not the average.

Centering: the one you can measure

Measure the left and right borders. The ratio is the bigger border over the total: 3 mm and 2 mm gives 3 ÷ 5 = 60/40. Do the same top/bottom, then flip the card over. The worse axis sets the cap.

10 Gem Mint55/4575/25
9 Mint60/4090/10
8 NM-MT65/3590/10
7 NM70/3090/10
6 EX-MT80/2090/10

Figures from PSA's grade definitions,[2] which PSA lets graders apply with some discretion for eye appeal.

Sources disagree on the PSA 10 line

Older copies of PSA's page read "55/45 to 60/40" for a 10 on the front.[3] PSA rewrote the wording in early 2025 without an announcement, and coverage of which way it went is contradictory.[4] psacard.com blocks automated reading, so check it in a browser. The safe working rule: 55/45 or better is a 10 candidate. 56–60 is a long shot at best, so price it as a 9.

Try it. These are the front borders of a card (Card A, below) measured at 2.9 mm left and 2.1 mm right:

Half grades: PSA also gives half grades from 1.5 through 8.5, for an exceptional card within its grade. There is no PSA 9.5. Above 9, the next step is 10.[5]

Which grader?

GraderKnown for
PSALargest grader and the resale benchmark. Usually earns the biggest premium for the same grade. No subgrades.[6]
BGS (Beckett)Four subgrades (centering, corners, edges, surface) and the Black Label, a 10 on all four.[7] Popular for modern high-end cards.
SGCBlack "tuxedo" slabs, and respected for vintage. Often cheaper.[6]
CGCCame over from comics. It's the main PSA alternative for Pokémon, and it splits the top grade into Pristine 10 and Gem Mint 10.[8]

One thing to know: PSA's parent company, Collectors, has owned SGC since 2024 and bought Beckett in late 2025. All three still grade under their own names.[6][7]

Is it worth grading? The math

PSA's prices moved a lot in 2026. The Value tiers ($24.99–$64.99) were paused on June 2 and, as of early October, still hadn't reopened.[9] On September 14 PSA opened a new Standard tier.[10]

PSA tier (Oct 2026)Per cardEst. turnaroundMax value
Standard (new)$59.9990–100 business days$1,000
Priority (was Regular)$79.9970–80 business days$1,500
Express$19920–30 business days$2,500
Premier (was Walk-Through)$5997–10 business days$10,000

From PSA's Sept. 9 announcement as reported by Heavy.[10] Prices change often, so confirm on psacard.com before quoting a customer. Return shipping is charged per order, based on declared value and card count.[11]

The formula

Expected graded value = (chance of 10 × PSA 10 comp) + (chance of 9 × PSA 9 comp) + (chance of 8 × PSA 8 comp)
Grade it if: expected graded value − (fee + shipping per card) > raw value.
Pull every comp from sold listings, matched by grade, exactly as in Lesson 3.

Worked example: same card, two copies

A hypothetical modern chrome rookie (illustrative numbers, not real comps): raw sells for $45, PSA 10 for $300, PSA 9 for $80, PSA 8 for $50. Cost: $59.99 Standard plus about $8 per card for shipping both ways on a five-card order (an estimate), so ≈ $68.

Card A: 58/42, cleanCard B: 52/48, clean
Your odds10: 5% · 9: 60% · 8: 35%10: 40% · 9: 50% · 8: 10%
Expected value$15 + $48 + $17.50 = $80.50$120 + $40 + $5 = $165
Minus ≈ $68 cost$12.50 (vs. $45 raw)$97 (vs. $45 raw)
CallSell raw.Grade it.

Six points of centering flipped the answer. Card A's centering caps it at 9 (borderline), and at $80 a PSA 9 doesn't cover the fee. Grading pays when the PSA 10 is a real possibility and the 10 is worth far more than the 9. The 4–5 month wait is also a real cost if the player's hype might fade. Think of the Pokémon version: a PSA 10 Charizard is worth sending, but a 9 of a common doesn't even cover the fee.


Practice

Answer from what you just read, without scrolling back up. The effort of recalling it is what makes it stick. Options are shuffled each time you load the page.

Real-world rep (15 minutes)

Take three raw cards from your own stack. For each: measure the front and back borders with a ruler (or zoom in on a phone photo), run them through the calculator above, then check corners and surface under a desk lamp. Write down a grade range. Then look up the PSA 10, 9, and raw sold comps on 130point and run the formula. Would you grade any of them at $59.99?

Something unclear, or want to argue with an answer? Ask me in the terminal. I'm your teacher for this, and questions like "how do I measure centering on a borderless card?" or "should I crack and resubmit a PSA 9?" are exactly what to bring.
