About Greenie Sports Cards

Steve Greenberg, also known as "Greenie," has been actively buying and selling sports cards full time since 2006. The Greenie Sports Cards team travels across the country to produce and attend live sports card shows and conventions, where they either set up a booth or embark on buying trips. Since 2007, we have proudly maintained a booth at The National Sports Collectors Convention. We are always eager to purchase single cards and full collections, including custom trading cards, so feel free to contact us at any time.

Greenie Sports Cards has evolved into one of the largest producers of live sports card shows in the nation, boasting over 30 events on the show circuit. This includes some of the Hobby's premier events such as the Great Lakes Collectors Convention, The Ohio State Card Show, and the Mountain State Collectors Convention, all of which feature a variety of custom trading cards.

Greenie Sports Cards launched its Media Division in January 2024, becoming the creators of the world’s first weekly live multi-stream hobby broadcast. Greenie Sports Cards Live! airs every Tuesday at 7pm EST across platforms including YouTube, Facebook, Instagram, LinkedIn, Twitter (X), and Twitch. Hosted by Jeremy Levine & Steve Greenberg, the show highlights Hobby News, Upcoming Card Shows across the country, and features interviews with athletes, coaches, influencers, producers, and personalities from the collectible universe, including insights into custom trading cards.

The show culminates with an exciting eBay Live auction at 9pm, hosted by Alex Schacht. Follow our social pages to catch the broadcast and interact with the show and its guests during these engaging live sports card shows.

Greenie Sports Cards launched its Custom Card Division in 2023, following the success and interest in custom trading cards produced as appreciation for participants in the 1st ever Great Lakes Collectors Convention.

Additionally, they boast a growing NIL roster of over 100+ student athletes across multiple schools and sports, showcased at various live sports card shows.
