The spring edition of the G.A.S. Card Show fills The Pavilion at John Knox Village in Lee's Summit, Missouri with 220 tables on Saturday and Sunday, April 3 and 4, 2027. April lands the show squarely at the opening of baseball season, and Greatest American Sportscard Shows schedules it that way on purpose — the Royals are back, new Topps and Bowman product is on shelves, and the room reflects it.
Baseball leads the floor this weekend. MLB dealers bring vintage Topps and Bowman runs, Royals and Cardinals inventory across every era, current prospect and rookie cards, and graded slabs from PSA, BGS and SGC. NFL remains strong year-round in this market with Chiefs rookies, autographs and patch cards. NBA playoff-season product, NHL, college, soccer, UFC and boxing all have their tables. Raw vintage sellers cover the 1950s through the 1980s in collector grades and at collector prices. Trading card game vendors handle Pokemon sealed and singles, Magic: The Gathering, Yu-Gi-Oh!, One Piece, Lorcana and Dragon Ball Z. Memorabilia dealers add signed jerseys, helmets, baseballs and photographs, game-used pieces, comics, bobbleheads and Funko Pops.
Hours are Saturday, April 3 from 10:00 a.m. to 7:00 p.m., and Sunday, April 4 from 10:00 a.m. to 5:00 p.m. Saturday morning is when the best individual cards move. Sunday afternoon is the strongest negotiating window of the weekend, because 220 dealers all reach the same conclusion at once about what they would rather not pack.
Admission is $5 per day or $8 for the weekend, paid at the door. Children 12 and under enter free. There is no separate VIP tier — one ticket, same access for everyone. Advance purchase is not required.
The Pavilion at John Knox Village is at 520 NW Murray Road in Lee's Summit with a large free on-site lot. It is a single open hall on one level, which makes a room this size genuinely navigable rather than maze-like. G.A.S. publishes hotel discount codes on their website for travelling collectors and dealers. Lee's Summit dining along Chipman Road and NW Blue Parkway is minutes away.
This show works across the board. Families get two days of access for $8 with kids free. Casual collectors can dig dollar and dime boxes across dozens of tables. Serious buyers get the largest concentration of competing dealers in the metro, which is the condition under which mispriced cards surface. Dealers and sellers should come Saturday morning and ask who is buying.
How to work it: complete one full lap of the hall before spending anything, mapping which tables carry your categories. Bring more cash than you intend to spend, in mixed denominations, and expect the cash discount to be meaningful. A written want list is not optional at 220 tables. Negotiate bundles instead of individual cards. If you can attend both days, buy your must-haves Saturday and save your discretionary spending for Sunday afternoon.
The complete G.A.S. tour calendar, dealer table pricing and hotel discount codes are published at gas-shows.com. The promoter posts vendor announcements and last-minute floor updates on Facebook ahead of each show.
