For pre-1980 cards, authentication and protection are often worth as much as the grade itself. A mid-grade vintage star in a slab usually sells for clearly more than the same card raw, because buyers trust that it is real and unaltered. Low-value vintage commons rarely justify the fee unless they are high grade. SGC slabs are popular with vintage collectors; compare sold prices for each company.
Quick math
- Break-even sale price ≈ (card value + grading fee + shipping + $0.40) ÷ 0.8675, plus outbound shipping. See the break-even formula.
- A $50 card graded at PSA Standard ($59.99) has to sell for about $144.54 to break even.
- Cheapest route in 2026: CGC Economy ($20) or CGC Bulk ($17 with 25+ cards). See CGC fees.
Before you submit
- Pull recent sold prices for the raw card and for each grade (10, 9, 8).
- Check centering, corners, edges and surface under a bright light. Be honest about the odds of a 10.
- Run the numbers for every grader in the calculator; it also flags upcharges.
