Meet the Expert Behind Baseball Card Adviser

Gary T. Leavitt, CFE, has turned a lifelong passion for baseball card collecting into a trusted advisory service. With decades of experience, he helps collectors understand, grade, and maximize the value of their collections.

Combining expertise in forensic accounting and real estate with industry knowledge, Gary offers ethical, professional guidance. From private sales to auctions, his nationwide services ensure collectors receive fair advice and the best possible outcomes for every collection.

While growing up in Northern California, Gary developed a love for baseball cards while collecting with his mother. Memorizing player statistics and trading with neighborhood kids became a lifelong passion that later shaped his professional career.

“I feel like a little kid every time I have the opportunity to review an old collection. Helping owners find the best solution to sell is what I enjoy most.”

Who Do We Work With

Many of our clients come through referrals from law firms, estate planners, family trusts, and investors. We provide expert guidance to anyone looking to understand, manage, or sell their baseball card collections.

01

Private Collectors

We are regularly contacted by collectors that want to stay anonymous and liquidate a collection without publicly taking it to the market. We ensure total privacy.

02

Law Firms

We work with law firms nationwide for expert analysis and valuation for their clients; as well as expert witness testimony and insurance advice.

03

Families with “found” collections

We’ve participated in some of the largest collections in the Country that are found by family members when cleaning out homes. Advising on what the collection consists of is our priority.

“Our goal is to make sure our clients have a ‘partner’ in their transaction.” 

Your Collection Deserves the Right Care

Every baseball card collection holds memories, history, and value. We help you protect that legacy while making the right decision with confidence, clarity, and trusted professional guidance.
