Should I Grade My Pokémon Card? The Expected-Value Method

Updated October 9, 2026 · 7 min read

Most "is it worth grading?" advice quietly assumes your card comes back a PSA 10. Most cards don't. The honest answer comes from weighting every grade your card could realistically get by how likely it is, then comparing that to what you'd pocket selling it raw today.

The one-line rule

Grade a card only when its expected graded value, minus every cost of grading, beats its raw sale price by a margin you care about. Everything below is how to put numbers on each part of that sentence.

Step 1: Find the real raw value

Use sold listings, not asking prices. On eBay, filter to Sold Items and look at the last 30–60 days of ungraded copies in similar condition. Ignore outliers (auctions that ended at 3 a.m., lots, damaged copies). The median of what's left is your raw value.

Step 2: Estimate your grade odds, not a single grade

Inspect centering, corners, edges and surface (our condition checklist walks through it). Then be honest about the spread. A card that "looks like a 10" to the naked eye might realistically be:

Pack-fresh modern cards still miss 10s regularly on centering and print lines you can't see without magnification. Build that in.

Step 3: Price each grade from sold comps

Look up recent sold prices for the card at PSA 10, 9 and 8. The gap between them is the whole game: for many cards a 9 sells for a fraction of a 10, and an 8 can sell for less than a clean raw copy.

Step 4: Compute expected graded value

Multiply each grade's price by its odds and add them up:

Expected value = (P10 × price10) + (P9 × price9) + (P8 × price8) + (P7 × price7)

With the odds above and comps of $520 / $250 / $160 / $110, that's 0.30×520 + 0.50×250 + 0.15×160 + 0.05×110 = $310.50.

Step 5: Subtract the real costs

• Grading fee for the service tier your card's value requires (check the grader's current fee schedule — tiers are capped by declared value).
• Shipping and insurance both ways.
• Time. Your money is tied up for weeks or months. Prices can move against you, and that cash could be flipping other inventory. Even a modest annual return on that capital is a real cost.
• Selling fees apply either way, but they scale with sale price, so a higher graded sale pays more in fees.

Step 6: Compare to selling raw today

Net gain from grading = Expected value − grading costs − raw value

Positive and comfortably so? Grade it. Near zero? Selling raw is usually the better trade — you skip the risk and the wait. Negative? Definitely sell raw.

Common mistakes

• Pricing off asking prices. Listings sit unsold at fantasy prices. Only sold data counts.
• Assuming a 10. The single biggest source of grading losses.
• Forgetting the floor. If a PSA 8 sells below raw, a bad outcome doesn't just reduce profit — it loses money.
• Grading low-value bulk. When the fee is a large share of the card's value, even a 10 often doesn't pay.
