Should you grade Garchomp & Giratina-GX #146?
Unified Minds · grading ROI analysis
Expected value is strongly positive — the gem rate is high enough to justify the PSA fee even accounting for sub-10 outcomes.
Ungraded
$39.94
PSA 10
$265.00
Gem rate
40.6%
PSA pop
3,427
The math
Breakeven sale price (raw price + PSA fee)
$39.94 + $25 = $64.94
You need to sell the slabbed card for at least this much to break even.
Projected PSA 10 uplift
($265.00 − $39.94 − $25) ÷ $39.94 × 100 = +501%
If you grade this card AND it returns PSA 10, this is your gross return on grading.
Expected value (uplift × gem rate)
501% × 40.6% = +203.6%
The real number. Adjusts for the fact that not every submission grades PSA 10.

What this calculator doesn't show
- Shipping costs. PSA shipping (in + out) typically adds $5–$15 per submission.
- Selling fees. eBay takes ~13% of gross; TCGplayer ~10%. Subtract from PSA 10 price for net proceeds.
- Holding cost. 30–60 day PSA turnaround means your capital is tied up.
- Sub-grade outcomes. A PSA 9 might still beat ungraded price, but a PSA 8 often doesn't. We model only the binary PSA-10-or-bust outcome — be more conservative for borderline cards.
- Market volatility. PSA 10 prices can swing 20%+ on news cycles. Today's calculated uplift is a snapshot.
