Crack-and-resubmit opportunities: slabs trading far below the next grade up. Both prices are sale-backed. Break-even = the share of resubmissions that must hit PSA 10 to cover the PSA 9 buy plus the grading fee.
| Card | Set | PSA 9 | PSA 10 | Multiple | Gap | Break-even | Gem rate | Pop |

Break-even uses each target grader's cheapest live service (PSA Regular, CGC Economy, BGS Standard), upcharged at the target value. A regrade is never guaranteed — a cracked PSA 9 can come back lower.
