The Diablo Valley Card Show returns to Concord High School on October 10 and 11, 2026, for a two-day card and collectibles weekend with more than 120 vendor tables spread across two rooms. Organized by a lifelong collector and Bay Area promoter who has produced card, toy, and collectible shows across Northern California for nearly five years, the show is built on a collectors-supporting-collectors philosophy that emphasizes fair pricing, strong vendor lineups, and a welcoming room for both longtime hobbyists and newcomers.
The floor is broad. Pokemon is the headliner, with vendors bringing modern chase cards, vintage holos, graded slabs, and sealed product, and the show's own billing highlights Magic: The Gathering and One Piece Card Game alongside Yu-Gi-Oh! and Disney Lorcana. Sports card dealers stock baseball, basketball, football, and soccer from vintage to modern and raw to graded, with a natural Warriors, 49ers, Giants, and Athletics lean. Vintage toys including action figures, Hot Wheels, Star Wars, and Transformers, comics from golden-age keys to modern variants, and sealed hobby boxes and blasters round out the room.
Hours had not been published for this edition at the time of listing; the June 2026 edition at the same venue ran 10:00 AM to 4:00 PM both days, and the October show is expected to follow suit. Saturday morning is when showcases are freshest; Sunday afternoon is when deals get sharpest.
Admission pricing follows the promoter's usual structure of a low general entry, typically around five dollars, with a VIP early-entry option and kids under twelve free with a paying adult. Confirm on the Eventbrite listing before attending.
Concord High School is located at 4200 Concord Boulevard, Concord, CA 94521, in the Clayton Valley area of eastern Concord, about ten minutes from Highway 242 and Interstate 680. Parking in the school lots is free. Restaurants along Clayton Road and in downtown Concord are minutes away.
This show suits families, Pokemon and One Piece collectors, sports card buyers, vintage toy and comic collectors who want a mixed show, and traders who appreciate a community crowd. Dealers looking for a friendly East Bay venue will find steady traffic.
To make the most of it, arrive at Saturday's open, bring cash for the best deals, and carry a want list and trade binder. Walk both rooms before buying, since the two-room layout means it is easy to miss a table, and bring cards to sell.
For tickets, vendor tables, and updates, follow @diablovalleycardshow on Instagram or check the organizer's Eventbrite page. The promoter's own site had not yet been updated for the October dates at the time of listing, so Eventbrite and Instagram are the reliable sources.
Regulars will note that this is the show's third Concord edition of 2026 after the April Concord Plaza Hotel weekend and the June high school show, and the organizer typically pairs each weekend with an official trade night at DVY Collectibles in Martinez the Friday before. Check Instagram for that announcement if you want to kick off the weekend early.
