Cooper Flagg Opens Flagg Trading Co. in Bangor, Maine

Cooper Flagg Opens First Card Shop in Bangor

2025-26 NBA Rookie of the Year Cooper Flagg marked another milestone in his fast-growing hobby presence on September 12, holding the grand opening for his new card store, Flagg Trading Co. The shop opened in Bangor, Maine, with Flagg launching the business alongside his cousin, Tyler Flagg.

The opening drew a strong response from collectors, with lines forming as early as 3 a.m. ahead of the 10 a.m. opening on Saturday. The early turnout underscored the excitement surrounding Flagg’s move into the sports card space and the anticipation around a new local hobby destination in Maine.

Flagg Trading Co. is the first location for the shop and is positioned to serve the Maine collecting community. Bangor sits about 30 minutes, or 26 miles, from Newport, Maine, where Flagg grew up. Before transferring to Montverde Academy, Flagg began his high school career at Nokomis Regional High School in Newport.

A Maine Connection That Resonates With Collectors

Flagg’s new shop adds another layer to his connection with the state that helped shape his basketball path. His hometown roots have already shown up in the hobby, including on his first Bowman card in the 2024-25 Bowman University set. That 1/1 Superfractor autograph was inscribed with “From the 207,” a direct nod to Maine’s area code and Flagg’s background.

That kind of personal connection has helped make Flagg one of the most compelling young names in the hobby. With Flagg Trading Co. now open, his presence in sports cards extends beyond his own collectibles and into a physical retail space that could become a regular stop for collectors in the region.

Flagg Joins a Growing Group of Athlete-Owned Hobby Shops

Flagg is the latest professional athlete to enter the hobby shop business, joining a list that includes Tom Brady, Candace Parker, and Mo Bamba.

Brady has been the most established name in the space through Card Vault by Tom Brady, which now has 20 shops open nationwide. One of those locations is in Dallas, just outside American Airlines Center, home of the Dallas Mavericks.

Parker announced in April that she was partnering with Score More Sports on a card store in Charlotte, North Carolina, with an expected opening in October. Bamba also recently opened Mo Bamba Cards and Collectibles Store near the UT Austin campus on September 11, one day before Flagg’s grand opening in Bangor.

That wave of athlete involvement reflects how the hobby continues to expand beyond trading cards alone. For collectors, athlete-owned stores bring added visibility to local shops while connecting the sports and collecting communities in a more direct way.

Flagg's Rookie Cards Continue to Drive Major Attention

Flagg’s shop opening comes less than a month after another major card moment in his young career. In early August, his 2025-26 Topps NBA Debut Rookie Patch Auto 1/1 was pulled by RhodyBreakers in Rhode Island, which is part of the Baseball Cards of Rhode Island retail shop.

The card quickly became a national hobby headline and remains the centerpiece chase in the set. As the main attraction in the product, Flagg’s Debut Patch Auto is expected to command a massive price, with the card already drawing serious attention from collectors and investors alike.

At the time of publishing, the card is live in Fanatics’ September Premier auction and has reached $2.2 million with ten days remaining. That figure reflects just how much interest surrounds Flagg’s earliest high-end rookie cards and how quickly his market has escalated.

What Flagg Trading Co. Means for the Maine Hobby Scene

For Maine collectors, Flagg Trading Co. offers a new local hub tied to one of the state’s most recognizable sports figures. The Bangor location gives fans and collectors a place connected to Flagg’s story, while also adding another retail presence to the broader hobby landscape.

The shop’s opening also highlights how modern athletes are shaping the card market in more ways than one. Flagg’s cards have already generated major headlines, and now his name is attached to a storefront that could become part of the collecting routine for hobbyists in northern New England.

With the grand opening now complete, Flagg Trading Co. enters the market at a moment when Flagg’s card value, hobby profile, and off-court influence are all rising at the same time.
