Sunday, August 9, 2026 closes out the Colorado Collectible Show's August 8–9 weekend at La Plaza Colorado in Aurora, and experienced Front Range collectors will tell you the second day plays very differently from the first. Saturday belongs to the early birds racing for fresh inventory. Sunday belongs to negotiators. By day two, dealers have a read on what is moving and what is not, and the cards still sitting in the case at noon are the ones most likely to leave with you at a number you like. If you have ever walked out of a card show wishing you had pushed harder on a price, Sunday is your day.
The floor carries the same broad mix that makes this recurring Aurora show useful. Sports tables span MLB, NBA, NFL, NHL, UFC, boxing, and soccer, with vintage Topps, Bowman, Fleer, and Donruss running alongside modern Panini Prizm, Select, Mosaic, Topps Chrome, and Bowman Draft. Rockies, Broncos, Nuggets, and Avalanche team collectors will find dedicated boxes worth digging through, and the venue's location makes it unusually strong for Liga MX, World Cup, and international soccer product. Trading card game inventory covers Pokemon from vintage WOTC through Scarlet and Violet and Japanese sets, Magic: The Gathering from Alpha reprints to current Standard, Yu-Gi-Oh!, One Piece, Disney Lorcana, Digimon, and Dragon Ball Z. Graded slabs from PSA, BGS, SGC, and CGC fill locked cases, and non-card tables carry comics, autographed memorabilia, Funko Pops, retro video games, and hobby supplies.
Sunday hours run 10:00 AM to 5:00 PM Mountain Time. Admission is free with no ticket required, and kids are welcome all day. There is no separate VIP tier or early-access charge, which keeps the whole thing refreshingly simple.
La Plaza Colorado is an indoor marketplace in Aurora, reachable from I-225 and East Colfax Avenue, with free on-site parking and a single accessible level. Food is available inside the plaza, so you can eat and come straight back to the floor. The climate-controlled space is a welcome thing in August, when the Front Range afternoon sun makes outdoor and warehouse shows uncomfortable by 2:00 PM.
Who should come on Sunday? Bargain hunters and patient buyers get the most out of it. Set builders finishing vintage runs benefit from dealers willing to break up lots at the end of a weekend. Parents bringing kids will find the second day calmer and less crowded, which makes a first card show far less overwhelming. Dealers and breakers scouting bulk lots often find their best per-card pricing in the final two hours.
Practical advice: bring cash and expect it to buy more than a card payment will, because many tables absorb processing fees mentally and price accordingly. Carry a want list with realistic target prices written next to each card so you are negotiating from a number, not a feeling. Bring sleeves, top loaders, and a small box. If you are selling, Sunday afternoon is when dealers with room left in their budget are most open to buying. Confirm hours through the Card Groove listing or Colorado hobby groups on Facebook before you drive out.
