Don't grade a modern Pokémon card unless the PSA 10 sells for at least $60-70 more than the raw copy. Below that gap, grading fees, selling fees and gem-rate risk eat the entire upside — and most modern cards sit well below it. The good news: the math is simple enough to run before you ever pay a fee.
The three numbers that decide everything
- All-in grading cost. Fee plus insured shipping both ways: realistically $20-35 per card at mainstream service tiers. Call it $28 for the math below.
- Gem rate. The probability your card comes back a 10. For well-screened modern submissions, community experience puts this around 50-65%. For cards straight from the pack with no screening, meaningfully lower — factory flaws are everywhere, as pack fresh isn't gem mint documents.
- The 9 penalty. A modern PSA 9 typically sells at or slightly below the raw NM price. You paid $28 to make your card worth roughly what it already was, minus the cost of a crack if you ever want it raw again.
Grading is a bet: you're paying ~$28 for a 50-65% shot at the 10 premium and a 35-50% shot at roughly nothing.
The worked break-even
Take a card worth $100 raw, with a PSA 10 at $180 and a PSA 9 at $90. Assume a solid 55% gem rate on a screened card, and 15% marketplace selling fees on whatever you sell (the same haircut the Pack Value Calculator applies by default).
- Slab path: expected sale = 0.55 × $180 + 0.45 × $90 = $139.50. After 15% fees: $118.60. Minus $28 grading: $90.60 net.
- Raw path: $100 × 0.85 = $85 net.
An $80 premium, a good gem rate, disciplined screening — and the edge is about $5.60. That's the honest shape of modern grading: even decent-looking setups barely clear the hurdle. Run the same numbers on a $30 card with a 2x premium (PSA 10 at $60, PSA 9 at $28) and the slab path nets about $12 versus $25.50 raw. The small card loses half its value to the attempt.
The general rule falls out of the algebra: at a 55% gem rate and 15% fees, the 10 premium must exceed roughly $60 plus 8% of the raw price before grading beats selling raw. Hence the headline number.
What clears the bar (and what never will)
Clears it: the top of the chase board. Cards like Team Rocket's Mewtwo ex SIR (~$559 raw in our July 2026 snapshot), Surging Sparks Pikachu ex SIR (~$338) or the Prismatic Evolutions Eeveelution SIRs carry 10 premiums in the hundreds of dollars. On those, a screened submission is genuinely +EV, and the raw-to-slab spread is a real edge — the systematic version of that game is covered in grading arbitrage.
Never clears it: the long tail. Double Rares, Ultra Rares, $15-40 Illustration Rares, promo cards. The market is drowning in modern slabs of ordinary cards — 9s that cost $28 to make and sell for $22. Population counts on popular moderns also grow relentlessly, which compresses 10 premiums over time; the dynamics are covered in PSA 10 premiums. You're not just betting on today's premium, you're betting it survives everyone else's submissions.
Screening: the free edge
The gem rate isn't fixed — it's a function of how hard you screen. Before submitting anything:
- Measure centering with the photo-and-pixels method in the card centering guide. Outside 60/40 front? Don't submit. This single check removes the most common 9.
- Inspect the surface under angled light for scratches, print lines and holo clouding, front and back.
- Check corners and edges under magnification. One whitened corner face is a 9 waiting to happen.
Cull ruthlessly and your gem rate climbs toward the top of the range; submit blind and you're donating fees. The difference between a 40% and 65% gem rate on the $100 example above is the difference between losing money and making it.
When raw is simply smarter
Sell raw when the premium is under the threshold, when you need the money on any timeline (grading adds weeks to months), when the card has any visible flaw, or when your goal is just protection — a $2 toploader protects nearly as well as a $28 slab. Grade your keepers if slabs bring you joy; that's consumption, not investment, and it's fine as long as you account for it honestly.
FAQ
What percentage of modern cards get a PSA 10?
Depends entirely on screening. Community experience suggests roughly half to two-thirds of carefully pre-screened modern submissions gem, while unscreened pack-fresh cards fare notably worse.
Is a PSA 9 modern card worth anything?
Usually about the raw price or a touch less. After grading and selling fees, a modern 9 is a net loss versus having sold the card raw.
Should I grade a card worth $50?
Almost never. A $50 card needs a PSA 10 price near $115+ to clear the math, and few $50 moderns have one. Sleeve it, toploader it, sell it raw.
