KC Cards and Collectibles Show runs Saturday, September 5 and Sunday, September 6, 2026 at the Yuma Fairgrounds Legacy Event Center, and it is the anchor collectibles weekend for Southwestern Arizona. Yuma sits far enough from both Tucson and Phoenix that collectors here have historically had to drive three or four hours to reach a proper show floor. KC Nerd Shack built this event to fix that, and the result is a two-day show that pulls attendees from across Yuma County, the Imperial Valley in California, and northern Sonora.
What is on the tables reflects that borderland audience. Sports card dealers stock MLB, NBA, NFL, NHL, and soccer, with soccer inventory noticeably deeper than at a typical Arizona show given the regional fanbase — Liga MX and international product turn up alongside Panini and Topps. Trading card game vendors bring Pokemon, Magic: The Gathering, Yu-Gi-Oh!, One Piece, and Disney Lorcana in singles and sealed. Rounding out the floor you will find graded slabs, comics, Funko Pops, anime figures, video games, and vintage toys. The nerd-culture breadth is intentional and it is what keeps non-card-collecting family members occupied for a couple of hours.
Hours are 11:00 AM to 7:00 PM on both Saturday and Sunday — an unusually long eight-hour day, and the late 7:00 PM close is genuinely useful in September when Yuma afternoons are still punishing. You can browse in the evening rather than baking in a midday parking lot.
Admission is FREE for both days. There is no ticket to buy, no VIP tier, and no early-entry upcharge listed. Kids come free as well. For a family weighing whether a two-hour drive is worth it, a zero-dollar door is the argument that closes it.
The Yuma Fairgrounds Legacy Event Center is at 2520 East 32nd Street in Yuma, with a large free on-site lot and easy access from Highway 95 and I-8. The Legacy Event Center is a proper climate-controlled hall rather than an open pavilion, so the interior stays comfortable regardless of what the September thermometer is doing outside. Restrooms are on site and food is generally available at or near the venue.
This show is a strong fit for families, casual collectors, and anyone in the Yuma or Imperial Valley area who does not want to make the drive to Phoenix or Tucson. It is also worth a look for dealers and serious buyers hunting outside the picked-over metro markets — regional shows like this one are where underpriced raw vintage still surfaces, because the local dealer pool is smaller and turnover is slower.
Tips for the best day: come Saturday morning for first look at fresh inventory, or Sunday afternoon if you are hunting discounts before dealers pack out. Bring cash, since smaller regional vendors are less likely to run card readers. Bring a want list and your own supplies. If you are bringing cards to sell, arrive early on Saturday while buying budgets are intact.
