KC Collectors Con takes over the Johnson County Fairgrounds in Gardner, Kansas on Saturday, October 3, 2026, billing itself as Kansas City's fastest-growing collectibles convention — and the growth is real. What started as a modest fairgrounds show has expanded into a full-day event that pulls dealers from across eastern Kansas and western Missouri, and the fairgrounds setting gives it far more floor space than the hotel ballrooms most metro shows are squeezed into.
Hours are 9:00 a.m. to 5:00 p.m. on Saturday, October 3 — a full eight-hour day, single day only.
Admission is $5 at the door.
The Johnson County Fairgrounds is at 136 E Washington Street in Gardner, Kansas, about thirty-five minutes southwest of downtown Kansas City and fifteen minutes past Olathe on I-35. Parking is free and abundant in the fairgrounds lots.
First-timers will find the fairgrounds atmosphere relaxed and the $5 entry low-risk.
Show announcements, vendor lineups and future dates are posted on the Kansas City Collectors Convention Facebook page.
