Era-specific aging models
Tobacco era (1909–1915), 1950s Topps, 1970s Topps, 1993 Magic — each era has a dedicated model variant accounting for natural paper aging.
Pre-1980 cards age differently than modern cards. Centering tolerances were looser; print quality varied wildly; paper has 30–70 years of natural change. SnapGrade has dedicated vintage tuning.

Vintage cards were notoriously off-cut. Our centering model knows that a 65/35 vintage centering is normal and graded differently than a modern 65/35.
Vintage cards develop toning over decades. We distinguish natural toning from artificial yellowing or damage.
Pre-1980 print runs had wildly inconsistent quality. Our model expects and accommodates wider print-quality variance on vintage cards.
Most AI card graders are trained on modern cards. Show them a 1952 Topps Mantle with natural 70-year toning and they'll flag it as surface damage. Show them a 1909 T206 with the era's typical 65/35 centering and they'll mark it down even though a vintage PSA grader would consider it perfectly centered for the era.
SnapGrade trained vintage-specific model variants for exactly this reason. The same four axes (centering, corners, edges, surface) — but with era-aware tolerance that matches how vintage graders actually grade.
