How to read this report
Graded is every copy PSA has ever slabbed, all grades combined. It measures how much a card gets submitted, which tracks demand more than rarity.
Gem rate is PSA 10s divided by graded. High gem rates mean the card is easy to gem and PSA 10s are not scarce; low gem rates mean surviving 10s are hard to make and usually carry a bigger premium over a PSA 9.
Rarest 10s only counts cards graded 50+ times, so a card with 3 PSA 10s out of 4 submissions does not show up as "rare". Populations only go up over time; check the refresh date above.
Deciding whether to grade one of these? Run the numbers in the PSA grading calculator or look up any single card in the pop checker.
