Some card shows include grading-company booths, authorized submission partners, or dealer-run drop-off services. Others have no grading intake at all. Check the official listing from the events calendar and confirm directly with the organizer or booth before carrying valuable cards. Ask which company receives the cards, whether authentication or grading is performed on-site or after shipment, and whether service levels or card types are limited during the event.
Treat show drop-off like any other custody transfer. You need an itemized receipt, card identifiers, declared values, service levels, fees, insurance terms, and a clear return process. The card show drop-off grading guide and PSA submission shop guide explain what to ask. If the paperwork feels rushed because a line is forming, step aside and slow down. Convenience at a show is useful only when your records are strong enough to track every card home. When in doubt, bring photos and a card list even if you decide not to submit.
