Greatest American Sportscard Shows closes out its 2026 Overland Park calendar with a free-admission Saturday show at American Legion Post 370 on November 7, 2026. The November date is the one Kansas-side collectors circle, because it lands right as holiday buying begins and dealers bring inventory calibrated for gift shopping as well as for the usual collector hunt.
Hours are Saturday only, 10:00 a.m. to 7:00 p.m.
Admission is free for everyone. Free entry is core to how G.A.S. operates and it keeps the room busy from open to close.
American Legion Post 370 is at 7500 W 75th Street in Overland Park, just off Metcalf Avenue. Parking is free in the Post lot and on the surrounding streets.
Free entry and a manageable size make it a good first show for families and newcomers.
The full G.A.S. tour calendar, dealer table pricing and hotel discount information are published at gas-shows.com, and the promoter posts show reminders and floor updates to Facebook in the days beforehand.
