Baseball Card Grading
Baseball grading is the oldest and deepest vertical in the hobby. Pre-war tobacco cards, Topps rookie-heavy post-war sets, and modern Bowman 1st / prospect cards all flow through PSA and SGC in huge volume.
What graders look for on baseball cards
Vintage baseball is brutally graded for corner wear and surface. Modern Bowman Chrome auto submissions almost always live or die on centering.
