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.

You have your stuff together and I been very proud to follow you on this journey with Money Ball Break$ and Grand Slam Sports Cards. Thanks for making collecting great brother.

Eric Kimbrel

Jeff at Moneyball Break$ is a great advocate of the sports card and collectibles hobby. Friendly, honest, very reasonable prices, and a great knowledge of the industry. For case breaks, he takes care of your cards as if they were his own by actually sleeving all hits no matter how small or big they may be, outstanding secure packaging and quick delivery. There are many choices out there, but Grand Slam & Money Ball Break$ are my choice time and time again and I highly recommend them to anyone I speak to within the hobby.

When choosing where to get the cards and memorabilia we collect, there are lots of choices, however no one takes care of you like Jeff Milliron at Money Ball Break$. From perfect packaging to on-time delivery and exceptional customer service, I’ll never go anywhere else. Whether you’re getting into a case break or buying a single pack, every transaction makes you feel like a VIP. I highly recommend Jeff to any collector either new or seasoned, you won’t regret the decision.
