Start by recording the card’s point thickness and physical format. Then inspect its condition and compare those details with the chosen grading company’s current holder and submission guidance, because the supplied sources do not establish a universal standard-holder limit.

Measure the Card’s Point Thickness

Card thickness is expressed in points, with one point equal to 0.001 inch. Measuring the card before choosing protective supplies or a grading route gives you a concrete specification to compare with a company’s holder guidance.

Do not assume that a memorabilia card matches an ordinary card merely because its length and width look familiar. A jersey insert, patch or layered construction can add substantial depth. Standard sleeves, semi-rigid holders and top loaders may not accommodate these thicker cards. Record the measured point thickness rather than relying on a visual estimate, and retain that figure for your submission check. It is the starting point for determining whether routine handling may apply or whether the card needs a thick-card option.

Identify the Card’s Physical Format

Thickness alone does not describe every holder requirement. Classify the card’s construction as precisely as the available information allows. The cited guides discuss jersey and patch memorabilia cards, multi-layer cards, folding booklets, jumbo cards and other oversized or unusual formats.

A thick card with conventional dimensions presents a different handling question from a booklet that folds open or a jumbo card with a larger footprint. Booklets and oversized formats may require specialty or custom submission handling, depending on the grading company. Record both the point thickness and the format, including whether the card folds or contains multiple layers. These two details provide a more useful basis for comparing the item with current company instructions than the broad label “memorabilia card” alone.

Inspect Condition Before Checking Eligibility

Examine the card before deciding whether and how to submit it. Check the edges, corners and surfaces, paying attention to areas where a thick or layered construction may show damage.

For cards with embedded memorabilia, inspect the window as a separate feature. The cited guidance identifies possible concerns including window lifting, displaced material, fraying and bulging. These features can be missed when an inspection follows only an ordinary-card checklist. Note what you observe without treating the inspection as a guaranteed prediction of a grade. The purpose is to create an accurate record of the card’s condition and construction before comparing it with holder requirements or packaging instructions.

Conclusion

Use a simple eligibility workflow: record the card’s point thickness, identify its physical format and document condition concerns around the edges, corners, surfaces and memorabilia window. Compare both thickness and format with the selected grading company’s current documentation.

The supplied sources do not support one universal thickness limit for standard holders. Acceptance can depend on the company and on whether the item is a thick conventional card, booklet, jumbo card or another unusual construction. Current holder limits, accepted formats, packaging rules, service options and fees therefore need direct confirmation. If the card falls outside routine published guidance, contact the chosen company for its applicable instructions. Before submitting, write down the thickness and format and verify every current requirement directly with that company.
