October kicks off at La Plaza Colorado with the Saturday session of the Colorado Collectible Show on October 3, 2026, the first weekend of a month that traditionally brings a wave of new dealers into the hobby room as football season shifts into high gear and collectors start thinking about holiday gift shopping a little earlier every year.
What attendees will find: the show floor mixes long-running local dealers with newer sellers testing out table space for the first time, and the result is a marketplace that swings between organized showcases of graded slabs and looser dollar-box tables where the fun is digging rather than browsing a case. Sports cards dominate — MLB, NBA, NFL, and NHL are all well represented, with football cardboard getting an extra push this time of year — while a smaller footprint of Pokemon, Magic: The Gathering, and Yu-Gi-Oh! singles rounds out the trading card game side. Collectors chasing memorabilia, vintage comics, or Funko Pops will usually find at least a table or two carrying each.
Hours: Saturday, October 3 runs 10:00 a.m. to 5:00 p.m. The show continues the next day, Sunday, October 4, on the same schedule, so collectors who can't make it out on Saturday get a second chance without waiting for another week to roll around.
Admission and parking: both are free, a point the organizers advertise heavily and one of the reasons the show has built a loyal weekly following rather than depending on one-off marketing pushes to fill the room every time.
Venue: La Plaza Colorado, 15200 E Colfax Ave, Aurora, CO 80011. The building doubles as a broader indoor marketplace, so beyond the card tables you'll find food vendors, an arcade, a bar for the adults, and a three-story play structure that keeps kids occupied while parents shop — a genuinely useful layout for a family outing rather than a card-only errand.
Who should attend: dealers looking to offload October football product fresh off release, grading-conscious collectors hunting for slabs at a lower price point than a big convention, and families who want an activity that doubles as a shopping trip. First-timers curious about the hobby will find this one of the least intimidating rooms in the metro to start in, since there's no cover charge and no pressure to buy anything at all.
Tips for the best experience: get there within the first hour for the freshest selection of any newly consigned collections, bring a printed or phone-based want list since tables turn over weekly, and don't be afraid to ask a dealer what they haven't put out yet — weekly shows often have inventory in boxes under the table that hasn't made it to the display case, and asking is the only way to see it.
