A Pokémon card crossover lets a grading company evaluate a card in another company's slab, without you opening the holder yourself. The minimum grade sets the lowest result you will accept before the service may remove and reholder the card. This approach reduces handling risk, but it does not eliminate grading uncertainty. Policies, fees, eligible holders, and minimum-grade rules vary, so confirm the chosen company's current terms before submitting.

What happens during a crossover?
A slab is the sealed plastic holder containing a graded card. During a crossover, the receiving grader initially examines the card through that holder instead of requiring you to crack it open. If the card appears to meet your minimum grade, the company may remove it and place it in a new slab.
If it does not qualify, the card generally remains in its original holder, subject to the service's rules. A crossover is not automatic grade conversion. An 8 from one company does not necessarily become an 8 elsewhere because grading standards, defect weighting, and authentication procedures differ.
How should you set the minimum grade?
Set the minimum grade according to the result you can actually accept, not the grade you hope to receive. Requesting a minimum of 9 means you would rather keep the existing slab than cross the card at 8 or below.
Three common choices illustrate the tradeoff: Consider a card graded 9 in its present slab. A minimum of 9 suits a collector who values grade preservation, while "any grade" may suit a registry collector who needs that grading company's holder. A minimum of 10 is a speculative upgrade attempt and may leave the card unchanged after fees.
- Same grade: Protects against an intentional downgrade while allowing a label change.
- Higher grade: Treats the submission as an upgrade attempt, but lowers the chance of crossing.
- Any grade: Prioritizes moving the card into the preferred holder, even if the number falls.
Why can a strong card fail to cross?
The grader must initially judge the card through plastic. Glare, scratches on the slab, dust, inner sleeves, and the holder's construction can obscure small defects. The receiving company may also weigh flaws differently.
Print lines, whitening, centering, surface indentations, factory cutting, and edge wear can prevent a crossover even when the existing grade seems reasonable. A failed crossover does not prove that the original grade was wrong. It may mean the card missed the new company's standard, or that the grader could not assess it confidently through the holder.
When does crossover make financial sense?
A crossover can make sense when the preferred holder improves collection consistency, registry eligibility, buyer confidence, or access to a particular marketplace. The potential benefit should exceed grading, shipping, insurance, and selling costs. Compare realistic outcomes rather than the highest possible sale.
A successful same-grade crossover may add little value, while a lower grade could reduce demand. A failed attempt can still leave you owing service and shipping fees. The existing slab also has value as protection and evidence of the current grade. Cracking it yourself gives the next grader an unobstructed view, but it surrenders that protection before a new grade is secured.
Checks to make before submitting
Read the current crossover instructions for the exact grading company and service level. Do not assume that policies described by another collector still apply. Before mailing the card: If keeping the present grade matters more than changing holders, enter that grade as the minimum and retain a copy of the completed submission form.
- Confirm that the existing grading company and holder type are eligible.
- Record the certification number and photograph both sides of the slab.
- Check whether the minimum grade includes qualifiers, subgrades, or special labels.
- Review what happens if authenticity, alteration, or holder problems are suspected.
- Calculate fees for a successful crossover, a failed crossover, and return shipping.
