The East Bay Card Show opens the 2027 spring season at the San Mateo County Event Center on Saturday, April 3 and Sunday, April 4, 2027. Produced by Tenth Inning Productions, the Walnut Creek-based promoter behind the East Bay Card Show, TCG NOW, and LA Card Expo, this series has become the most consistent large card show on the Peninsula, and an early-April date means baseball's Opening Week is in full swing when the doors open.
Expect a full two-day floor of sports cards and trading card games. Tenth Inning shows cover the whole hobby, from vintage baseball and graded slabs to modern rookies and sealed wax. With a new MLB season underway, Giants and Athletics inventory, fresh Topps Series 1 and Bowman releases, and prospect autographs should be in heavy rotation, while NBA playoff races keep Warriors and national basketball cards moving. NFL, NHL, soccer, UFC, and boxing dealers round out the sports side. TCG vendors carry Pokémon singles and sealed product, One Piece Card Game, Magic: The Gathering, Yu-Gi-Oh!, and Disney Lorcana, and the promoter's own marketing also highlights Funko Pops and trending collectibles. Graded slabs from PSA, BGS, SGC, and CGC fill the display cases throughout the hall.
Listings show the doors opening at 9:30 AM on Saturday, April 3, with the show running until 4:00 PM, and the Sunday session typically follows the series' standard 10:00 AM to 4:00 PM format. Tickets are sold in advance through the Tenth Inning Card Show website, and the promoter warns that tickets sell out fast; pricing for the April edition had not been posted at the time of writing, so check the ticket page closer to the date.
The San Mateo County Event Center at 1346 Saratoga Drive is a large fairground complex with on-site parking and quick access from US-101 and State Route 92. It sits almost exactly halfway between San Francisco and San Jose, which is why it draws dealers and collectors from the entire Bay Area. The Hillsdale Caltrain station is a short walk from the grounds for anyone coming by train, and Hillsdale Shopping Center is nearby for food.
This show is ideal for serious sports collectors, graded card buyers, TCG players filling decks, dealers restocking for the season, and families; the large hall means aisles are generally easier to navigate than at hotel ballroom shows. First-timers get a realistic look at what a big regional show offers.
Tips: buy tickets online early, since East Bay Card Show events routinely sell out. Arrive at opening on Saturday for first crack at fresh inventory, or come Sunday afternoon if you prefer negotiating with dealers who would rather not pack up. Bring cash plus a card, a want list, top loaders, and a bag for purchases.
