What's the minimum raw card value to consider grading?

Rule of thumb: cards under $30 raw rarely justify the math because grading fees + shipping + eBay fees absorb most of the slab premium even at the gem grade. Exceptions: chase Pokémon ex / SIR cards under $30 raw with 25%+ gem rate and PSA 10 comps above $300 — those can flip profitably. Always run the specific card through the optimizer rather than relying on the rule.

Should I crack and re-submit a card that came back at a 9?

Sometimes — but the math is harsh. A crack-and-resub costs another grading fee + return shipping, and PSA's review-and-grade for already-slabbed cards isn't free. Run the EV math treating the PSA 9 sale price as your floor (you can always sell as-is) vs. the EV of a re-grade attempt accounting for the chance you grade lower than 9 (it happens). For most cards, the answer is to sell the PSA 9 and move on.

How long does grading take?

Varies wildly by tier. PSA's express tiers turn around in 5-10 business days; their bulk service can take 90+ business days. CGC and BGS are typically faster at equivalent tiers. The optimizer doesn't bake in time-decay risk by default; for fast-moving Pokémon ex sets that risk is real.

What if my card has off-centering?

Off-centering is the #1 cause of cards grading 9 instead of 10. If your copy looks visually 60/40 or worse, the population gem rate doesn't apply to you — your effective rate is likely 1/4 of population. PSA in particular weighs centering heavily; CGC and SGC are slightly more lenient. Honestly assess your copy before sending in.

Is it cheaper to grade in bulk?

Per-card grading fees usually drop 30-50% at bulk tiers (requires 20+ cards in one submission). Bulk tiers have longer turnaround. The trade-off: more cards at lower fee but later sale prices. For a portfolio of clearly-positive-EV cards bulk is correct; for a single high-value flip, the express tier's faster turnaround usually wins.

Should I Grade This Card? A Decision Framework

The fast answer to "should I grade this card?" is to run the grading optimizer on it. The optimizer handles the math; you read the verdict. But the math depends on inputs, and the inputs depend on judgment calls. This page walks the five questions you should answer before trusting the verdict on a specific card.

1. What's the gem rate for this card?

Gem rate is the population-share of submissions that graded at the top grade. PSA's public Pop Report is the authoritative source — look up your specific card by name and set. For a worked walkthrough of gem-rate math, see what is gem rate.

Quick reference:

Under 5% — typical for vintage WOTC Pokémon and pre-Modern MTG. Grade-flips only viable when the PSA 10 comp is 10×+ raw.
5-15% — typical for early modern cards. Marginal flips; the optimizer often lands WATCH here.
15-30% — typical for modern Pokémon ex / SIR. Most flips in this band are GRADE-positive if PSA 10 comp is at least 4× raw.
30%+ — chase cards with clean print runs. Almost always GRADE when the math is run.

Adjust downward for your specific copy if it visibly has centering or surface issues.

2. What's the PSA 10 vs raw multiple?

The whole grading-flip thesis is that the gem premium dwarfs the fee. Compute:

multiple = PSA_10_comp / raw_market_price

Rough thresholds:

Multiple	Verdict heuristic
< 3×	SKIP — slab premium isn't enough to cover the fee + variance
3–5×	WATCH — depends on gem rate; bullish flips only at 20%+ rate
5–10×	GRADE candidate — most rates support positive net
10×+	GRADE — even sub-10% gem rates often profitable

Find the multiple by looking at eBay sold-listings filtered to PSA 10 (sort by date descending) and dividing by current raw market. The optimizer surfaces both numbers for any card.

3. Is the comp data current?

Stale comps lie. A card that sold for $1,000 PSA 10 a year ago might sell for $600 now or $1,500 now. Always look at the most recent 90 days of sold listings, not lifetime.

For modern Pokémon ex / SIR cards: comps change fast — re-verify weekly.
For vintage WOTC: comps are slower-moving but the trend matters. Has the price been trending up or down over the past 12 months?
For MTG modern legendaries (Sheoldred, Wrenn, etc.): comps move on Modern format changes — a banning can drop a comp 50% overnight.

Cardboard Assets pulls comp data nightly via the hybrid comp pipeline. Every card surfaces its comp freshness chip (Verified · Fresh · Aging · Insufficient). If the chip is Aging or Insufficient, treat the verdict as directional rather than prescriptive.

4. Can my specific copy hit a 10?

Honestly inspect your card before sending it in. The four PSA 10 disqualifiers:

Centering. Look at the white border on all four sides. If one side is more than ~60/40 visually, PSA 10 is unlikely. CGC is slightly more forgiving but the principle is the same.
Corners. Any whitening, fraying, or roundness fails 10. A magnifier helps.
Edges. Run a fingernail along each edge. If you feel ridges, it's not a 10.
Surface. Hold under angled light. Print lines, scratches, fingerprints, or "snow" all fail 10. Modern Pokémon foil curl is a common surface flaw.

If you find any flaw, your card's gem rate is the population rate × 0.25 (rough heuristic — flawed copies grade 9 at population rate at best). Run the optimizer math with the adjusted rate.

5. Can I afford the median outcome?

EV is the average outcome. Half the time you do better; half the time you do worse. If the median outcome (grading at the 9 tier, typical of a 70% 9-rate vintage card) leaves you holding a slab worth less than what you paid + fees, that's a loss you have to be okay with.

Math check:

downside = comp_9 − raw − grading_fee − shipping − ebay_fee_on_comp_9

If downside is more negative than you're willing to absorb, the EV-positive verdict doesn't help — you can't afford to grade many cards at once at this risk level. Scale back to cheaper cards or higher-gem-rate cards.

Final decision

If all five answers point the same direction:

Gem rate ≥ 10% AND multiple ≥ 5× AND comps fresh AND copy looks clean AND downside tolerable → GRADE
Any one of those is off → WATCH (wait for the bad input to improve, or grade only after a price move)
Two or more off → SKIP

Then sanity-check against the optimizer's automated verdict. They should agree. If they don't, look at the optimizer's input chips — gem-rate source, comp source, comp age. The optimizer's defaults can be wrong on a specific card; you can override and see the verdict shift.
