The Lynbrook Sports Card Show, presented by Behind the Diamond Cards, sets up at the New York Elks Lodge, 57 Hempstead Avenue in Lynbrook, on Saturday, October 10, 2026, from 9:00 AM to 3:00 PM. It is the Nassau County sibling of the promoter's monthly Babylon show, held in a lodge hall in the heart of Lynbrook village and built around a core of Long Island dealers who know the local market. For collectors in the Five Towns, Rockville Centre, Valley Stream, and southwestern Nassau it is the closest traditional Saturday sports show.
Sports cards are the focus. Baseball leads, with vintage Topps and Bowman, modern Chrome and Prizm, prospects, and graded rookies, while football, basketball, and hockey tables carry rookies, autographs, numbered parallels, and slabs from PSA, BGS, and SGC. Memorabilia and supplies are available, and a few dealers bring Pokemon and other trading card games, though they are a minority of the floor. As a shop-run show, expect the promoter's own table to be well stocked and to be buying.
The show runs a single session from 9:00 AM to 3:00 PM. Admission is a low door fee typical of Elks Lodge shows; check the Behind the Diamond Cards listing on ontreasure.com or the shop's social pages for the current price. Kids are welcome and the room is family-friendly. Dealers here actively purchase collections, so bringing cards to sell is a good use of a Saturday morning.
The Elks Lodge is on Hempstead Avenue in downtown Lynbrook, a few minutes' walk from the Lynbrook LIRR station, where the Long Beach, Far Rockaway, and Babylon branches all stop, making this one of the most train-accessible shows on Long Island. Drivers will find free parking at the lodge and municipal lots in the village. Sunrise Highway and the Southern State Parkway are both close. Atlantic Avenue and Merrick Road nearby have delis, bagel shops, and restaurants.
Who should attend: southwestern Nassau collectors of every level, baseball set builders, autograph and slab buyers who want to handle cards before purchasing, parents with young collectors, and dealers looking for a dependable local show with a repeat crowd. First-timers will find it relaxed and easy.
Tips: arrive at 9:00 AM for first pick, bring cash, and bring a list of the players and sets you are chasing. Sort and price anything you intend to sell so dealers can make quick offers. The next Lynbrook date is December 12, 2026, and the sister Babylon show runs monthly on Sundays. For table reservations and updates, follow Behind the Diamond Cards on Instagram or Facebook. The Lynbrook and Babylon shows share many of the same dealers, so if you are working on a set it pays to attend both and let the vendors know what you are chasing; they will often bring requested cards to the next date.
