The Monsignor Slade Sports Card & Collectibles Show returns to Glen Burnie on Saturday, September 12, 2026, kicking off the busy fall season for Baltimore-area collectors with one of the region's most beloved community card shows. Hosted in the gymnasium of Monsignor Slade Catholic School at 120 Dorsey Road, this HASA fundraiser has been a fixture of the Anne Arundel County hobby calendar for years, drawing a friendly mix of longtime dealers, local families, and first-time browsers. With free admission and proceeds supporting the school's athletic association, it is the kind of low-pressure, welcoming show that makes a perfect on-ramp into the hobby.
Inside, expect rows of vendor tables packed with sports cards spanning every era and every major sport — MLB, NBA, NFL, NHL, plus UFC, boxing, and soccer. You will find vintage Topps, Bowman, and Fleer from the 1950s through the 1980s, stacks of affordable 1990s junk-wax boxes perfect for set builders, and modern Panini Prizm, Donruss Optic, Select, and Topps Chrome for the prospectors and breakers. Baltimore Orioles and Ravens collectors come out in force, and Maryland-area dealers reliably stock deep regional inventory. Beyond cardboard, tables feature graded slabs (PSA, BGS, SGC), autographed memorabilia, game-used pieces, vintage comics, Funko Pops, and a growing selection of Pokémon, Magic: The Gathering, and Yu-Gi-Oh! singles and sealed product for the trading-card-game crowd.
The show runs Saturday from 9:00 AM to 2:00 PM EDT. Admission is free, which is a rarity among card shows and one of the biggest reasons the event stays so well attended. Many dealers offer better deals in the final hour as they look to lighten their inventory before packing up, so plan your visit accordingly.
Monsignor Slade Catholic School sits at 120 Dorsey Road, Glen Burnie, MD 21090, just off Interstate 97 and Maryland Route 10, with quick access from the Baltimore Beltway (I-695) and Baltimore-Washington Parkway. The location is convenient for collectors coming from Baltimore, Annapolis, Severna Park, Pasadena, and the broader BWI corridor. On-site parking is free and plentiful, and the venue is fully accessible.
This show fits every kind of collector — families looking for an affordable weekend outing, kids chasing their favorite Orioles and Ravens players, vintage hunters digging through dollar boxes, set builders, and serious buyers seeking graded vintage. Tournament players and TCG collectors will find singles to round out decks and binders too.
For the best experience, arrive close to the 9:00 AM opening for first crack at fresh inventory, then circle back near closing for end-of-day discounts. Bring plenty of cash — many smaller dealers prefer it and will cut better deals for it, though several accept Venmo, Zelle, and PayPal. Carry a written want list, penny sleeves, and a few top loaders to protect your finds, and don't be shy about asking dealers to dig out boxes that aren't on display.
