Start with a dated listing from the events calendar, then follow the organizer’s official source. A legitimate show should identify the date, venue, city, hours, admission, contact method, and often vendor or autograph details. Be cautious with copied flyers that have no year, posts from accounts that do not control the event, or payment requests for tables through personal accounts with no contract. If the venue is large or unfamiliar, check that it also lists or confirms the event.
Look for continuity. Established promoters usually have past events, real contact information, and a consistent web or social presence. New shows can be legitimate too, but they should still communicate clearly and answer practical questions. The 2026 card show calendar guide explains why source verification matters. When in doubt, contact nearby local card shops to ask whether they know the organizer. Do not send vendor fees or travel a long distance based only on an undated image.
