MDC Card Connection was founded in 2026 with a simple mission: to connect collectors with the cards they’re chasing most. Based in New Jersey and operating both online and at trade shows across the country, we specialize in the upper echelon of sports and trading cards—whether that’s a true “holy grail” or the key hit needed to complete a collection.

We pride ourselves on being both a trusted destination to buy and one of the best places to sell your cards. With a focus on fair, transparent pricing and consistently strong deals, MDC Card Connection is built around the collector experience. Our goal is to make high-end card transactions feel straightforward, honest, and rewarding—no matter which side of the table you’re on.
