Perfect five stars and a wall of Eagles gear — this Trenton shop pairs sports cards and memorabilia with a fan-apparel selection nobody else nearby carries.
Underground Sports Collective holds a flawless 5.0 across its Google reviews, and the reason is not what you would guess. Half the people who write about it lead with the clothing. "Was so happy to see a huge selection of sportswear especially Eagles," one customer wrote after driving an hour to get there. That hybrid — card shop crossed with fan-apparel boutique — is genuinely rare in Mercer County, which sits right on the Eagles-Giants fault line.
The card side is sports through and through. Graded slabs and raw singles across baseball, football, basketball and hockey, vintage pieces mixed in with modern, plus autographed memorabilia and collectibles. This is not a TCG shop; do not come looking for a draft pod or a Pokemon binder. Come looking for a Phillies rookie, a signed helmet, or a jersey you cannot find at a mall kiosk.
Mike and Anthony get named by customers again and again, and a separate reviewer credits the owner directly — so expect more than one person who actually knows the inventory. The shop is small enough that a conversation is the default rather than a transaction, and word of mouth is clearly doing the heavy lifting: a modest social footprint, an outsized review score, and customers making the drive from well outside the area.
Hours are refreshingly straightforward for a card shop — 10AM to 6PM Monday through Friday, 11AM to 5PM Saturday, closed Sunday. That daytime-weekday schedule makes it one of the few options in the area you can hit on a lunch break rather than after dinner.
The shop is on Carnegie Road just off the Route 1 corridor, with parking on site. They also work the pop-up circuit, announcing new collection drops and appearances on social, so following along is worth it if you want first look at fresh inventory before it hits the case.
