The Johnson County Card Show holds its October edition at the Homefield Olathe Training Center on Saturday, October 10, 2026. This is the series in its standard one-day format — a tight, well-run free show that has become the default Saturday destination for Johnson County collectors and a regular stop for dealers working the Kansas side of the metro.
Hours are 10:00 a.m. to 4:00 p.m. on Saturday, October 10 — a six-hour single-day window, which is shorter than the two-day editions and changes the rhythm considerably.
Admission is free.
Dates for the November and December editions, plus vendor table pricing, are posted on cardshows.io and on the Shake and Bake Sports Cards social channels, where the operators publish vendor lineups the week before each show.
