The Johnson County Card Show throws its Halloween Bash at the Homefield Olathe Training Center on Saturday and Sunday, October 31 and November 1, 2026. Holding a two-day show on Halloween weekend is a bold call, and the Shake and Bake Sports Cards crew leans into it — costumes are welcome, the atmosphere is looser than a normal Saturday show, and the room usually picks up a family crowd in the morning before trick-or-treating takes over the evening.
Underneath the theme it is a serious card show. The sports floor carries MLB from vintage Topps through current Bowman prospects, NFL deep into Chiefs season inventory with rookies and autographed patches, NBA opening-month product, NHL, college and soccer. Graded slabs from PSA, BGS and SGC line the display cases. Vintage raw dealers work the perimeter with 1960s, 1970s and 1980s baseball and football. Trading card game vendors handle Pokemon singles and sealed, Magic: The Gathering, Yu-Gi-Oh!, One Piece, Lorcana and Dragon Ball Z, and the Halloween edition typically draws extra horror-adjacent inventory — comics, monster and horror non-sport sets, Funko Pops and signed memorabilia.
Saturday, October 31 runs 10:00 a.m. to 5:00 p.m. Sunday, November 1 runs 10:00 a.m. to 5:00 p.m. as well. Saturday morning is the strongest for selection. Halloween afternoon thins out noticeably as families leave to get ready for the evening, which makes late Saturday an unusually good and unusually quiet buying window. Sunday runs at a normal weekend pace throughout.
Admission is free on both days. There is no VIP tier and no advance ticketing, and children with an adult get in free. Simply walk in during open hours.
Homefield Olathe Training Center is an athletic facility in Olathe, Kansas with a large free surface lot at the door. The building is single-level, wide-aisled and well lit, and it handles strollers and wheelchairs comfortably. Restaurants along the 119th Street corridor in Olathe are a few minutes away for a mid-show break.
This edition is particularly good for families — the costume-friendly atmosphere makes it an easy sell to kids who might not otherwise want to spend Saturday morning at a card show, and the dime and dollar boxes give them something to actually do. It is equally worthwhile for serious collectors, and the quiet Halloween afternoon is a genuine tactical advantage if you can be there for it.
How to play it: come Saturday morning for first pick, or come Saturday between two and five if you would rather have the room mostly to yourself and dealers with time to talk. Bring cash in mixed denominations. Carry a want list organized by sport and set. Walk both aisles fully before spending. Make bundled offers rather than single-card offers — the discount is consistently better. And ask dealers what they have that is thematically Halloween; several bring horror and monster material specifically for this weekend and it does not always make it onto the table.
Vendor lineups, table pricing and the December schedule are posted on cardshows.io and on the Shake and Bake Sports Cards social channels in the week leading up to the show.
