Klein's Kards

Klein’s Kards is a New York City father-and-son sports card brand run by Matt and Dillon Klein. Built around two generations of collecting, it shares the excitement of the hunt and the stories behind the cards. The family’s collection has a particular passion for the Knicks, with legends such as Patrick Ewing, Walt Frazier, Willis Reed, Bernard King, John Starks, and Jalen Brunson featured among its favorites.

The shop offers sports cards, including newly listed finds, graded gems, and raw rookie cards, with Knicks cards taking the lead alongside selections from other eras. Klein’s Kards also showcases its personal collection of Knicks legends and family keepsakes, which it describes as not for sale. For collectors looking to connect and shop in real time, Matt and Dillon host live card openings, breaks, and deals on Whatnot, often on most nights. The brand’s merchandise includes tees, hoodies, and hats. Klein’s Kards brings collecting, family, and Knicks fandom together through its online shop, live streams, and social channels.
