Gem RateOf every copy PSA has ever graded, the share that came back a perfect 10.————
Gem Premium (10:9)How much more a PSA 10 costs than a PSA 9 of this card. 2.5× means the perfect copy sells for 2.5 times the near-perfect one.————
Vs ExpectedThis card's price vs what you'd expect for a card with its PSA 10 population in its era. 9× means the market pays nine times what rarity alone explains — collector demand. Below 1× means it's cheaper than its scarcity suggests.————
