Worked example (assumptions you can change)
The card costs and sells raw for $100. Assumed graded sale prices are multiples of raw: 10 = 3.0×, 9 = 1.4×, 8 = 0.9×, 7 or lower = 0.6×, with grade odds of 25% / 45% / 22% / 8%. These are illustrative, not market data: replace them with sold comps and your own read of the card.
| Grade | Odds | Sells for | eBay fee | Profit after all costs |
|---|---|---|---|---|
| 10 | 25% | $300.00 | $40.15 | $124.85 |
| 9 | 45% | $140.00 | $18.95 | -$13.95 |
| 8 | 22% | $90.00 | $12.33 | -$57.33 |
| 7 or lower | 8% | $60.00 | $8.35 | -$83.35 |
All-in cost: $100.00 card + $20.00 CGC fee (Economy (90 working days)) + $10 round-trip shipping = $130.00. Odds-weighted profit = $5.65; selling raw nets -$18.65. To beat selling raw, the chance of a 10 must be about 9.7% with the other grades keeping their relative odds.

What differs for football cards
Football rookie prices swing with performance and injuries, and demand peaks in season. Many sets have borders that show edge chipping and centering issues. Quarterback rookies hold the deepest graded market; mid-round players seldom justify a fee.
Grader acceptance and category rules change: confirm on the grader’s own site (PSA · SGC · BGS · CGC). Fees checked October 14, 2026.
