The Round Rock Sports & Memorabilia Expo on June 6–7, 2026 brings a sports-first card and memorabilia show to Dell Diamond, home of the Round Rock Express Triple-A affiliate just north of Austin. Uniquely for a card show, the expo runs in conjunction with a home Express series weekend, so attendees can pair show admission with a minor league baseball game and a full weekend of Central Texas sports.
The floor is squarely sports-focused — easily 85% sports cards and memorabilia with a smaller TCG footprint on one end of the concourse. Sports card dealers cover MLB (heavy emphasis, fitting the venue), NBA, NFL, NHL, UFC, boxing, golf, and soccer. Expect strong vintage Topps and Bowman depth, modern Prizm, Chrome, Donruss, Select, and high-end Flawless and National Treasures, plus a deep autograph and memorabilia section — game-used jerseys, signed baseballs, signed helmets, ticket stubs, program runs, and MiLB and MLB oddball. A smaller TCG section handles Pokémon, Magic, Yu-Gi-Oh!, and One Piece for anyone who wants to round out their pickups.
Day-by-day hours: Saturday, June 6 — VIP 10:00 AM, GA 11:00 AM to 7:00 PM (Round Rock Express home game Saturday at 6:30 PM, ticketed separately). Sunday, June 7 — GA 10:00 AM to 3:00 PM (Express home game Sunday at 1:05 PM, ticketed separately). Show admission: $8 single day, $12 two-day, $30 VIP (includes early entry, swag bag, and a voucher toward an Express game ticket, subject to availability). Kids 10 and under free with paying adult.
Dell Diamond is at 3400 East Palm Valley Boulevard in Round Rock, just off State Highway 79 and easy to reach from I-35 or Toll 130. Free parking is available in the stadium lots, with entry to the show through the main concourse gate. The show floor is covered and climate-controlled during summer heat. Wheelchair accessibility throughout the venue is excellent — Dell Diamond is a modern stadium with full ADA provisions.
This show is a dream for sports-focused collectors. Vintage baseball hunters often rate the Round Rock show among their top two or three Texas stops of the year for fresh raw 1950s and 1960s inventory. Memorabilia buyers find game-used, autograph, and MiLB items that rarely show up at general TCG-heavy shows. Families love the ballpark vibe and the option to follow up the show with an evening Express game. Autograph signings from current and former Express, Astros, and Rangers players are routinely announced in the two weeks leading up to show weekend.
Tips: bring cash for the sharpest pricing on high-end slabs and signed pieces, a PSA-grade checklist, and a padded carry case for any memorabilia pickups. Arrive VIP Saturday for first crack at autograph signings with shortest line times. If combining with the Express game, buy game tickets separately through Round Rock Express's site.
