Tenth Inning Productions closes out its 2026 Bay Area calendar with the East Bay Sports Card Show at the San Mateo County Event Center on December 19 and 20, 2026, the weekend before Christmas. This holiday edition uses the event center's large exhibition halls to host one of the promoter's biggest Peninsula floors of the year, and the timing makes it the Bay Area's best last-minute stop for hobby gifts, year-end collection sales, and one final grail hunt before the calendar turns.
As the name signals, sports cards lead. Expect deep NFL, NBA, MLB, and NHL inventory from vintage Hall of Famers and graded rookies to modern autographs, numbered parallels, and case-fresh wax, with heavy 49ers, Warriors, Giants, and Sharks representation and soccer, UFC, and boxing cards at multiple tables. Trading card game vendors are still well represented with Pokemon singles, slabs, and sealed product alongside Magic: The Gathering, Yu-Gi-Oh!, One Piece, and Disney Lorcana, and holiday tins and booster boxes are prominent in December. Memorabilia, Funko Pops, and collectibles fill out the aisles, and prize drawings run over the weekend.
Hours run Saturday, December 19 and Sunday, December 20 from 10:30 AM to 5:00 PM each day. Saturday is when the best showcase cards move; Sunday afternoon is when dealers are most willing to cut a deal rather than pack inventory away for the holidays.
Admission follows Tenth Inning's standard pricing of about ten dollars per day with kids free alongside a paying adult; tickets are sold online through the promoter's site and at the door. Advance purchase is recommended since holiday shows draw large crowds. Confirm pricing and any VIP option before attending.
The San Mateo County Event Center is located at 1346 Saratoga Drive, San Mateo, CA 94403, just off Highway 101 at Hillsdale Boulevard or Highway 92. On-site parking is available for a fee, and the Hillsdale Caltrain station is nearby. Hillsdale Shopping Center's restaurants are minutes away, which makes it easy to combine the show with holiday errands.
This show suits serious sports card collectors and dealers, gift shoppers hunting sealed product, families thanks to free kids' entry, and anyone looking to sell a collection before year-end. Traders will find a large, active crowd.
To make the most of the weekend, buy tickets in advance, arrive at Saturday's open, bring cash and a written want list, and lap the full floor before buying. Ask vendors about bundle pricing on sealed product, and bring cards to sell since dealers are buying.

Collectors who attended the Thanksgiving-weekend San Mateo show three weeks earlier will recognize most of the dealer lineup, which makes this a good date to follow up on cards that were set aside or out of budget. Many Tenth Inning regulars also take pre-orders for January releases at the December show, so ask about upcoming product if you have a set in mind.
