Jeff & Kaysie Milliron

Jeff Milliron and Todd Carter have joined forces to continue the legacy of Joe Hocevar at Grand Slam Sports Cards in Chagrin Falls, Ohio - just outside of Cleveland. Joe opened the shop in 1993 and provided an outstanding experience for all customers through 2020. 

Jeff and Todd began a working relationship in June 2019, starting a box / case breaks group called Money Ball Break$. The room has grown to over 3,100 members and exhibits a strong community of some of the best collectors in the hobby. When the opportunity arose to expand with Grand Slam Sports Cards, Jeff and Todd couldn't resist. 

Background on Jeff / Kaysie: 

I have collected cards throughout my life since the age of 10. Some of my fondest memories as a child are traveling around with my mom to card shows and gathering autographed memorabilia of sports legends. As an adult, I have been an avid collector of sports cards and memorabilia through various channels (online, card shows, retail stores). I currently serve as room administrator to operate Money Ball Break$ and am very excited about the opportunity to help you meet your collection goals. 

Kaysie Milliron (Jeff's wife of 11 years) will be leading our direct to consumer business, ensuring our website and social media offers a great variety of products at competitive prices. 

Background on Todd:

I remember the days of trading baseball and Pokémon cards with neighborhood friends... no top loaders of course (ugh!). During high school and college, much of my focus was on academics and sports so I took a break from sports card collecting. Once getting into my professional career (2013), I fell back in love with the hobby and started to learn more and more about the hobby (i.e. top products as investor, card grading, how to evaluate future prospects). I've learned more with Money Ball Break$ than I've ever known and look forward to helping share some of those learnings with you at Grand Slam Sports Cards.
