The Colorado Collectible Show's Sunday session returns to La Plaza Colorado on October 4, 2026, giving Aurora-area collectors who missed Saturday's opening day of the month a second full day to dig through tables before the weekly show resets again next Saturday.
What attendees will find: Sunday crowds at this show tend to run a little slower-paced than Saturday's, which regulars say makes it easier to actually talk to dealers rather than fight for table space. Expect the same broad mix as always — sports cards across MLB, NBA, NFL, and NHL, a rotating selection of Pokemon, Magic: The Gathering, and Yu-Gi-Oh! singles and sealed product, graded slabs from PSA, BGS, and SGC, and scattered tables of memorabilia, comics, and Funko Pops. Because inventory turns over so quickly on a weekly show, a Sunday visit after a busy Saturday can turn up entirely fresh boxes that got restocked overnight while you slept.
Hours: 10:00 a.m. to 5:00 p.m. on Sunday, October 4. For collectors who work weekends, La Plaza Colorado also runs a shorter Thursday evening session from 5:00 to 7:00 p.m. most weeks — worth keeping in mind if a Sunday doesn't fit your schedule going forward into the fall.
Admission and parking: free entry, free parking, no ticket required — walk in any time between opening and close, no reservation or advance sign-up of any kind needed.
Venue: La Plaza Colorado, 15200 E Colfax Ave, Aurora, CO 80011. The venue's food court, arcade, bar, and three-story playground make it one of the more comfortable indoor spaces in the metro to spend a full afternoon, particularly as outdoor markets start winding down for the season in October and the weather turns unpredictable.
Who should attend: this is an especially good entry point for beginners and kids getting into the hobby, since the calmer Sunday pace makes it easier to ask a dealer basic questions — how grading works, what a rookie card premium is, how to spot a reprint — without feeling rushed by a line behind you. Serious collectors chasing a specific vintage set or player will also want to check in weekly, since low weekly turnover combined with persistence tends to pay off over a few visits rather than one.
Tips for the best experience: bring cash in small denominations for dollar-box digging, bring a phone or printed want list, and if you're new, don't hesitate to ask a dealer to walk you through a graded slab's label — most sellers at a recurring local show like this one are happy to explain the hobby to a newcomer, which isn't always true at bigger, busier conventions where lines move fast and dealers are stretched thin across dozens of customers at once.
