DSG Presents brings the Sonoma County Card & Collectibles Show to the DoubleTree by Hilton in Rohnert Park on Saturday and Sunday, August 15 and 16, 2026. The North Bay does not get many two-day hotel-ballroom shows, which is what makes this one worth the drive up Highway 101 — it is the anchor collecting event for Sonoma, Marin, Napa, and Mendocino counties, and dealers who normally only work the Peninsula and South Bay circuit make the trip north for it.
The vendor floor covers both halves of the hobby. Sports card dealers stock MLB, NBA, NFL, NHL, UFC, boxing, and soccer across every era — 1950s and 1960s Topps and Bowman vintage, 1970s and 1980s runs that set builders still chase, junk-wax commons in dollar boxes, and modern Panini Prizm, Donruss Optic, Select, Mosaic, Contenders, Topps Chrome, Bowman Draft, and Stadium Club. San Francisco Giants, San Francisco 49ers, Golden State Warriors, San Jose Sharks, and Oakland Athletics inventory runs deep, and there is usually strong Sacramento Kings and Santa Rosa junior college and Sonoma State alumni interest as well. Trading card game tables carry Pokémon singles and sealed from vintage through Scarlet and Violet, Magic: The Gathering, Yu-Gi-Oh!, One Piece, Disney Lorcana, Dragon Ball Super, and Digimon. Locked cases display PSA, BGS, SGC, and CGC graded slabs, and additional tables carry autographed memorabilia, signed baseballs and jerseys, vintage comics, Funko Pops, retro video games, and supplies.
Hours run 10:00 AM to 5:00 PM Pacific on Saturday and 10:00 AM to 5:00 PM Pacific on Sunday. Admission is a modest door charge in line with regional hotel shows, typically with children admitted free alongside a paying adult; confirm current pricing with the promoter before you travel, as DSG does not always publish an advance ticketing page.
The DoubleTree by Hilton Sonoma Wine Country sits at 1 Doubletree Drive in Rohnert Park, directly off Highway 101 at the Golf Course Drive exit, roughly fifty minutes north of the Golden Gate Bridge. Parking on site is free and plentiful — a real advantage over San Francisco and Peninsula venues. The ballroom is climate-controlled, carpeted, and ADA-accessible, and the hotel restaurant and bar are steps from the show floor. Rohnert Park and neighbouring Cotati and Santa Rosa offer plenty of dining, and the wine country setting makes this an easy show to build a weekend around.
The show fits serious collectors who want a proper two-day event without driving to the Peninsula, North Bay families looking for a weekend outing, set builders, TCG players, and dealers buying raw collections from walk-in sellers. It is also approachable for first-timers — large enough to have real inventory, small enough to talk to everyone.
For the best results, come Saturday morning when the fresh inventory is out and dealers are most willing to trade. Bring cash for leverage, a want list sorted by sport and set, penny sleeves and top loaders, and a carrying box. Sunday afternoon is the better window for bargain hunting, when dealers would rather sell than repack. If you are selling a collection, arrive early Saturday and bring it organized — sorted lots get better offers than shoeboxes.
