The South Shore Showdown Card Show fills the Long Island Sports Dome at 5600 Old Sunrise Highway in Massapequa on Saturday, November 7, 2026, from 9:00 AM to 3:00 PM. Produced by South Shore Events, it is the promoter's biggest show, with more than 120 tables available, sports cards and every major trading card game under one roof, raffles every two hours, music, and a concession stand. The dome is one of the largest indoor spaces used for a card show on Long Island, which gives the Showdown room to grow into a regional draw for Nassau and Suffolk collectors.
The floor is deliberately split. Sports card dealers bring MLB, NBA, NFL, and NHL inventory, with modern rookies, autographs, numbered parallels, graded slabs, and vintage from a number of veteran tables, and November puts football and basketball in the spotlight. Trading card game vendors cover Pokemon first and then Magic: The Gathering, One Piece, Yu-Gi-Oh!, Lorcana, and Dragon Ball, with singles, sealed product, and graded cards. Supplies, memorabilia, and collectibles tables fill in around them. With 120-plus tables, the selection is closer to a convention than a legion-hall show.
Hours are 9:00 AM to 3:00 PM in a single session. Admission is 5 dollars, and kids under 10 are free, which keeps the show affordable for families. Raffles run every two hours throughout the day, so staying for the full show has a payoff. The concession stand means you do not have to leave for lunch, and the music keeps the atmosphere lively.
The Long Island Sports Dome is at 5600 Old Sunrise Highway in Massapequa, just off Sunrise Highway near the Nassau-Suffolk line, with easy access from the Southern State Parkway and Seaford-Oyster Bay Expressway. The dome has a large free parking lot. The Massapequa LIRR station on the Babylon Branch is a short rideshare away, and the N19 bus runs along Sunrise Highway. Sunrise Highway has every restaurant option within minutes.
Who should attend: South Shore collectors of every kind, families with kids under 10, sports card buyers in the middle of football season, Pokemon and TCG collectors who want a large floor without going to the city, and dealers who want a big Long Island crowd. First-timers will find it well organized and easy to navigate despite the size.
Tips: arrive at 9:00 AM for the best selection across 120 tables, bring cash, and bring a want list covering both sports and TCG targets so you can work the room efficiently. Stick around for the raffles, and bring a trade binder because collector trading is welcome. For vendor tables, updates, and flyers, join the South Shore Events Facebook group, where the promoter posts show details. With the holidays approaching, November is also a good month to shop for sealed product as gifts, and several vendors typically bring discounted lots for that reason.
