Cross-Grade Arbitrage
Some companies' 10s sell for more than others'. This board finds cards where cracking your slab and resubmitting to the higher-value company nets you more, even after the crossover fee. Source is what you already own (or can buy); edge is what you'd gain after regrading at the better company.

How this works
Each row is a card where one company's 10 sells for more than another's. You hold (or buy) the cheaper 10, crack it, and resubmit to the company whose 10 trades higher. The Edge is what you'd net at current sold prices: the target price minus the source price minus the base submission fee. Edge % is that same number divided by what you paid.
Source is the slab you already own or can buy; target is the company whose 10 trades highest for that card. A card often crosses well from more than one company, so we show the best option per card and the Options column reveals the rest. Filtering by Source company picks the right option for you: choose the company your slab is in and you'll see that card's crossover, even when it isn't the card's single best.
The Comps column is the smaller of the two sale counts behind the prices. Under 5 means the estimate is thin and the edge may not hold up in practice.
The Gem column is the card's gem rate: the share of submissions that come back a 10. A higher gem rate means it's likelier to re-grade a 10, so the crack is lower risk. By default we rank by raw edge. Flip the Gem-weighted toggle to rank by expected edge (the edge times the gem rate), which floats reliable crossovers above big but risky longshots. Either way, the Edge shown is the real value if it does come back a 10.
Before you crack a slab
- This assumes the card re-grades a 10, and not all of them do. PSA centering is stricter than CGC or TAG, so a crossover can come back a 9 or lower and sell for less than the 10 you cracked.
- Gem rate is the card's overall gradeability, not a promise for your exact copy. Centering and condition still vary slab to slab.
- These are observed market prices, not guaranteed sale prices. None of this is financial advice.
