PSA vs SGC vs CGC: Which Grader for Baseball Cards?
The three major grading services don't price equally. We compare turnaround, market premium, modern vs vintage strength, and submission economics so you pick the right slab for the right card.
May 7, 2026
Bottom Line: PSA dominates baseball at 75%+ market share — its slabs command the highest secondary premiums and the most liquid resale. SGC has caught up on vintage and offers faster turnaround. CGC is a strong third, especially for modern. Pick by card era, budget, and exit strategy.
Head-to-Head Comparison
| Metric | PSA | SGC | CGC |

When to Choose Each
Choose PSA when:
- The card is meaningful and you plan to sell at retail or auction
- It's a vintage HOF rookie where every dollar of premium matters
- You're building a registry set (PSA registry is the largest)
- You can afford the turnaround time
Choose SGC when:
- You need fast turnaround (consign-and-flip workflows)
- The card is pre-1980 — SGC's vintage reputation is excellent and the premium gap to PSA narrows
- You're submitting bulk (lower per-card pricing)
- You want the strictest grader (SGC is consistently the toughest)
Choose CGC when:
- The card is modern and you're grading in volume
- You also collect comics (CGC is the comics standard, single submission account)
- You want CGC's sub-grades for centering, edges, surface, corners (free on modern)
- The economics work: bigger discount on slab cost may offset the resale gap
The Cross-Over Math
Cracking and resubmitting ("crackouts") is the dirty secret of grading economics. A SGC 9 of a 1956 Mantle that becomes a PSA 9 typically gains 25-40% in resale value. The math works above ~$300 card value.
