description	Use when evaluating whether to crack and resubmit a graded card to a different grader for higher value. Includes EV formula and risk model.

Crossover Arbitrage

EV = (P_higher × higher_price) − (P_lower × lower_price) − fees − damage_risk. Crack only when EV exceeds current market by >15%.

The crossover EV formula

Example: BGS 9.5 with sub-grades 9.5-10-9.5-10. Crack and submit PSA:

• 50% PSA 10 ($300), 40% PSA 9 ($80), 10% damage ($30)
• EV = (0.5×300) + (0.4×80) + (0.1×30) − $35 = $150
• Current BGS 9.5: $120
• Crossover EV: +$30 (worth it)

When crossover pays

1. BGS 9.5 with sub-grades ≥ 9.5-10-9.5-10 → PSA 10 (~50% hit rate)
2. SGC 8 vintage → PSA 8 (no grade change, +5-15% liquidity)
3. CGC 10 modern Pokemon → PSA 10 (~70% hit rate when CGC 10 issued)
4. Old PSA 9 with strong sub-grade indicators → BGS 9.5+ Pristine candidate

When it loses money

1. BGS 9 mixed sub-grades → PSA risk: typically 9, no premium
2. SGC 9 vintage with paper toning → PSA may give 8 or qualify
3. CGC 10 with sub-9.5 sub-grades → PSA almost certainly 9 or below
4. 8.5/9 modern — resubmit fee + risk usually exceeds upside

Mechanical risk

Cracking damages: hairline scratch -1 to -2; edge nick -1; fingerprint cleanable. Use proper de-slabbing tools. Practice on a junk card first. NEVER touch bare-finger to surface during transfer.
