Pokémon PSA gem rate
A card’s gem rate is the share of graded copies that come back PSA 10. A rate of 10% means nine in ten submissions miss the top grade — the single biggest factor in whether grading a card pays. Measured across 16,925 Pokémon cards with PSA population data. See also the PSA population report and grading ROI.
Getting harder to gem
A lifetime gem rate averages every submission ever made, so it moves slowly and hides what is happening now. These cards gemmed at a lower rate in recent submissions than they have historically — scarcity being confirmed as more copies are graded, rather than assumed. Based on 3 weeks of weekly population snapshots, so treat it as directional; it sharpens as the history grows.
Hardest cards to gem
The lowest PSA 10 rates among cards with at least 100 graded copies — centring, print lines and edge wear keep these off the top grade.
Easiest cards to gem
The highest PSA 10 rates on the same floor of at least 100 graded copies — modern printing and thicker stock make the top grade far more reachable.
