On Saturday, August 29, 2026 the Colorado Collectible Show runs its regular weekend session at La Plaza Colorado in Aurora — on the same day the enormous Denver Card Shows event fills the National Western Livestock Center across town. Collectors who know the metro treat this as an opportunity rather than a conflict. When a thousand-table show pulls the crowds north, the Aurora floor gets quiet, and a quiet floor with motivated dealers is exactly where deals happen. If you would rather have unhurried conversations and real negotiating room than fight through convention-hall crowds, this is the better Saturday.
The dealer mix stays broad and generalist. Sports card tables carry MLB, NBA, NFL, NHL, UFC, boxing, and soccer, with vintage Topps, Bowman, Fleer, and Donruss beside 1990s wax and modern Panini Prizm, Donruss Optic, Select, Mosaic, Topps Chrome, and Bowman Draft. Rockies, Broncos, Nuggets, and Avalanche inventory is standard, and with the NFL season days away, Broncos collectors will find dealers stocked and ready to talk. The venue's location on Aurora's east side keeps it unusually strong for Liga MX, Panini World Cup, and other international soccer product. Trading card game vendors bring Pokemon spanning vintage Wizards of the Coast releases through Scarlet and Violet and Japanese-language sets, plus Magic: The Gathering, Yu-Gi-Oh!, One Piece, Disney Lorcana, Digimon, and Dragon Ball Z. Locked cases display PSA, BGS, SGC, and CGC graded slabs, with additional tables for comics, autographed memorabilia, Funko Pops, retro video games, and supplies.
Hours are 10:00 AM to 5:00 PM Mountain Time, and admission is free for all ages with no ticketing or registration. There is no paid early access, so everyone hits the floor at the same time.
La Plaza Colorado is a climate-controlled indoor marketplace in Aurora, reached easily from I-225 and East Colfax Avenue. Parking is free and on site — a concrete advantage over the National Western Center, where parking runs $15 per day. The single-level layout is accessible, and food vendors within the plaza make it easy to stay for the full session.
This day suits patient buyers, families, and anyone who dislikes crowds. Bargain hunters do well because dealers facing a slow Saturday would rather sell at a workable number than pack up unsold. Set builders and team collectors get time to actually dig through commons boxes instead of being elbowed along. Competitive TCG players can talk trades properly. First-timers get a far gentler introduction than a 1,000-table hall provides.
A practical suggestion worth considering: do both. Hit the National Western Livestock Center when it opens, work the big floor for two or three hours, then drive twenty minutes to Aurora for a calmer afternoon with cash still in your pocket and a clear sense of what things are actually worth. Bring cash in mixed bills, a want list with target prices, sleeves, top loaders, and a box. Confirm hours through the Card Groove listing before you go.
