Saturday, September 5, 2026 is the full-day centerpiece of the All C's Collectors Showcase at the Arapahoe County Fairgrounds Event Center in Aurora, a three-day Labor Day weekend event carrying more than 300 dealer tables. Friday evening is the preview session and Sunday is the wind-down, but Saturday is when the event is operating at full capacity — every table staffed, every case filled, and the widest cross-section of Front Range collectors in the building. If you attend only one day of the weekend, this is the one.
All C's has a long history in Colorado collecting, and the showcase reflects that pedigree in the range of material on the floor. Sports card dealers cover MLB, NBA, NFL, NHL, UFC, boxing, and soccer across every era — 1950s and 1960s Topps and Bowman vintage, 1970s and 1980s Topps, Fleer, and Donruss, 1990s refractor and insert product, and modern Panini Prizm, National Treasures, Donruss Optic, Select, Topps Chrome, and Bowman Draft. Colorado Rockies, Denver Broncos, Denver Nuggets, and Colorado Avalanche inventory runs deep, and the Labor Day timing catches the NFL season opener and the tail of the baseball pennant race, both of which drive real energy on the floor. Trading card game tables stock Pokemon from vintage Wizards of the Coast sets through Scarlet and Violet and Japanese imports, Magic: The Gathering, Yu-Gi-Oh!, One Piece, Disney Lorcana, Digimon, and Dragon Ball Z. Locked cases hold PSA, BGS, SGC, and CGC graded slabs, and additional vendors bring autographed memorabilia, game-used relics, comics, Funko Pops, vintage toys, coins, and hobby supplies.
Saturday hours run 10:00 AM to 5:00 PM Mountain Time. Admission is free, and children are welcome throughout the day at no charge — unusually generous for a 300-plus-table event and a big part of why the showcase draws families rather than only serious buyers.
The Arapahoe County Fairgrounds Event Center is located in Aurora with straightforward access from E-470 and Quincy Avenue, and offers extensive free on-site parking. The event center is a single-level, climate-controlled, ADA-accessible hall with concessions available — a comfortable setting for a long day, and the free parking is a meaningful saving compared with downtown Denver venues.
Saturday works for everyone: serious buyers chasing graded vintage and high-end modern, set builders working long runs, team collectors, breakers restocking, families making a holiday-weekend outing of it, and first-timers who want scale without the overwhelm of a 1,000-table hall. Competitive Pokemon, Magic, and One Piece players find strong singles selection ahead of fall Front Range tournaments.
To get the most out of the day, arrive at 10:00 AM and take a quick orientation lap before buying anything so you know where the material you want actually is. Bring cash in mixed bills plus Venmo and Zelle, a want list sorted by sport and set, penny sleeves, top loaders, and a carrying box. Revisit the tables you flagged after 3:30 PM, when dealers become notably more flexible. Confirm hours and the dealer roster before you go.
