About Us
A Family Business Built on Passion and Purpose
Mint Gem Sports, LLC is a New Jersey-based, family-run sports card company founded by a father and his teenage son. What started as a fun weekend activity quickly turned into a shared passion — and now a growing business. We built Mint Gem Sports to spend more quality time together, strengthen our bond, and bring the joy of collecting to others who love the hobby as much as we do.
Our Story
From flipping through vintage cards in plastic sleeves to pulling fresh rookies straight out of a pack, we’ve experienced firsthand how collecting brings people together. It’s more than just cardboard — it’s about the stories, the players, the excitement of a great find, and the connection between generations.
Together, we’ve turned our shared love for sports and collecting into a business that reflects trust, fun, learning, and family values. Every card we sell is selected with care — as if it were going into our own collection.
