The Gemhaus Card Show comes to the Embassy Suites Walnut Creek on September 26 and 27, 2026, bringing a two-day card show to central Contra Costa County. Organized by Gemhaus, a Bay Area grading-and-collectibles brand, this show gives East Bay collectors a full weekend of sports cards, Pokemon, and trading card games in a comfortable hotel setting right off Interstate 680, and it lands on the same weekend as several other Bay Area shows, which makes Walnut Creek an easy add-on for anyone touring the region.
The floor covers the full hobby. Sports card dealers bring NFL, NBA, MLB, and NHL inventory with a Warriors, 49ers, Giants, and Athletics focus, from base rookies and dollar boxes to graded slabs, autographs, and numbered parallels. Trading card game vendors stock Pokemon singles, vintage holos, graded cards, and sealed product, with Magic: The Gathering, One Piece Card Game, Yu-Gi-Oh!, and Disney Lorcana also represented. Given the organizer's grading background, expect a strong showing of graded inventory and on-site advice about submitting cards for grading. Funko Pops and collectibles round out the room.
Hours run Saturday, September 26 and Sunday, September 27 from 10:00 AM to 5:00 PM each day. Saturday morning brings the freshest showcases; Sunday afternoon is when vendors deal most freely before packing out.
Admission pricing and table counts had not been published at the time of listing. Check the show listing on TCDB or Gemhaus's social channels for confirmed entry pricing and any VIP option before attending.
The Embassy Suites Walnut Creek is located at 1345 Treat Boulevard, Walnut Creek, CA 94597, at the intersection of Treat Boulevard and Interstate 680, directly across from the Pleasant Hill/Contra Costa Centre BART station. Hotel self-parking is available, and the surrounding Contra Costa Centre has restaurants within walking distance. Downtown Walnut Creek's shopping and dining is a few minutes away.
This show suits East Bay and Contra Costa collectors who want a weekend show close to home, families looking for a transit-accessible outing, Pokemon and sports card buyers, and anyone curious about grading who wants to talk to the organizer directly. Traders will find an engaged crowd.
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. Lap the whole floor before buying, use Sunday for follow-up deals, and bring cards you are considering for grading to get a second opinion.
For confirmation of admission, hours, and vendor tables, check the TCDB listing or follow Gemhaus on social media.
The BART-adjacent location is a real advantage for this show. Collectors coming from San Francisco, Oakland, or Berkeley can ride the Yellow Line directly to Pleasant Hill/Contra Costa Centre and walk across the street, which makes this one of the most car-free-friendly card shows in the Bay Area.
