PSA
PSA 10
$91.97
Real prices from PriceCharting's per-grade table — its generic “Grade N” reflects PSA-graded sales. CGC / BGS / TAG sub-10 grades are estimated from this card's real PSA price at that grade × that grader's 10-to-PSA-10 ratio (this card's own real pair when available, else a ratio calibrated from real catalog cards in the same era and rarity). Grades with no real anchor and low-confidence estimates are omitted — a blank beats a bad number.
