The Gem Mint Trade Show lands at the Harbor Center in Slidell on Saturday, August 1 and Sunday, August 2, 2026, bringing a full weekend of buying, selling, and trading to one of the Northshore's premier event venues. With its name borrowed from the highest grade a card can earn, this show sets its sights on quality - and the spacious Harbor Center exhibit hall gives dealers room to spread out far beyond what the region's hotel-ballroom shows can offer.
Expect a broad and balanced floor. Sports card dealers bring MLB, NBA, NFL, and NHL inventory ranging from vintage stars to the latest rookies, with graded PSA, BGS, and SGC slabs, raw singles, wax boxes, and memorabilia throughout the room. Saints, Pelicans, and LSU material is always a regional staple. The TCG side is equally represented, with Pokemon vintage and modern singles, sealed product, and graded keys alongside Magic: The Gathering, Yu-Gi-Oh!, One Piece, and Lorcana. Many tables also carry Funko Pops, comics, coins, and other collectibles, giving the show a something-for-everyone feel.
Doors open at 10:00 AM on both Saturday and Sunday, with the floor typically running into late afternoon. Saturday brings the largest crowd and the freshest inventory; Sunday is the value day, when dealers become noticeably more flexible on price rather than pack unsold stock back into the van.
Admission is inexpensive and family-friendly - expect free or low-cost entry at the door, with no advance tickets required. Kids are welcome, and the roomy exhibit hall means strollers and family groups can navigate comfortably even at peak hours.
The Harbor Center at 100 Harbor Center Boulevard sits just off I-10 at the Oak Harbor exit in Slidell, minutes from the I-12 and I-59 interchanges, which puts it within an easy drive of New Orleans, the entire Northshore, and the Mississippi Gulf Coast. Parking is free and abundant, and the building's modern, air-conditioned hall is a comfortable place to spend an August afternoon in Louisiana.
This is a show for everyone: serious collectors get a bigger dealer pool than the area's smaller monthly shows, players can restock across every major game, families get an affordable weekend outing, and sellers can shop their collections to multiple buyers under one roof. If you have been sitting on cards to sell or trade, a two-day show at a venue this size is the right place to test the market.
A few tips for the best experience: arrive at Saturday's open for first pick of showcased slabs, bring cash because it still closes deals faster than anything else, and walk the full floor before committing to a big purchase - with this many tables, prices on the same card can vary meaningfully. Bring a want list, and if you are trading, come with an organized binder and realistic expectations. Ask dealers what they are buying, too; several actively purchase collections at shows like this.
