Twin Oaks Shows holds its Sunday card show at The Commons at Federal Way on September 20, 2026. Late September is quietly one of the most interesting periods on the collecting calendar. Baseball's regular season is ending and playoff races are settling, which sharpens interest in specific players and rookie cards almost overnight. Football is three weeks in, and the draft class rookies that looked like speculation in August now have game tape attached. Fall trading card game sets are on shelves. Prices move, and shows like this are where that movement becomes visible before it shows up in online comps.
The Sunday Twin Oaks format is card-focused and unhurried, and the floor covers the full range. Sports dealers stock MLB, NBA, NFL, NHL, UFC, boxing, and soccer across every era — 1950s and 1960s Topps and Bowman vintage, 1970s and 1980s stars and rookies, plentiful and cheap junk-wax-era wax and singles for set builders, and modern Panini Prizm, Select, Donruss Optic, Topps Chrome, Bowman, and Bowman Draft. Northwest team inventory is a consistent draw: Seattle Mariners, Seahawks, Kraken, Sounders, Storm, Washington Huskies, Washington State Cougars, Gonzaga, and Tacoma Rainiers.
Gaming tables reach from Wizards-era Pokémon printings up through the current Scarlet and Violet block, with Japanese singles and sealed alongside. Magic: The Gathering, Yu-Gi-Oh!, One Piece, Disney Lorcana, Dragon Ball Z Fusion World, and Digimon each hold space. Fall organized play is in full swing, so competitive Pokémon, Lorcana, and One Piece players use these Sundays to source singles at better-than-online prices. Locked cases hold graded slabs from PSA, BGS, SGC, and CGC, and accessory vendors carry sleeves, top loaders, one-touch magnetics, binders, and storage boxes.
Hours are 11:00 AM to 4:00 PM Pacific Time. Admission is free and parking is free, with no VIP tier and no early-entry ticket. Twin Oaks has held that policy for nearly forty years, and it remains the single biggest reason these shows draw families and newcomers alongside long-time regulars.
The venue sits at 1928 South Commons in Federal Way, an I-5 exit roughly equidistant from downtown Seattle and downtown Tacoma. Everything about the setup favors a long visit: acres of free parking between the surface lot and the garage, a heated interior, elevators and accessible restrooms throughout, and a food court close enough that a mid-show lunch costs you ten minutes rather than an hour.
Who should attend: baseball collectors tracking playoff races, football collectors evaluating rookies with real data, set builders, families, budget collectors, competitive TCG players, and sellers looking for offers on material they want to move before the holidays.
For the best results, arrive at the 11:00 AM open. Bring cash in small bills plus Venmo, a want list, and penny sleeves and top loaders. If you are buying playoff-adjacent baseball or hyped rookies, compare at least three tables before committing — late-September pricing on hot names varies widely and some sellers are still working from August comps, which cuts both ways. Ask dealers what came in during the week, and revisit anything you hesitated on near the 4:00 PM close. Confirm the date at twinoaksshows.com.
