Established in 1985, Lelands is the world’s first sports memorabilia and card auction house, and the premier appraisers and authenticators in the entire sports hobby. Its founder, the late Josh Leland Evans, was a pioneer in the field and acknowledged by his peers as the most knowledgeable figure in sports memorabilia. Renowned in his own right, Evans’s long-time partner Michael Heffner continues Lelands’ four decade tradition of personal customer service and maximizing results for clients. 

Lelands has handled many of the largest landmark auctions, achieving world-record prices for countless cards and iconic memorabilia including a Tom Brady rookie card ($3.1 million), Babe Ruth's 1927 Yankees World Series ring ($2.09 million), Ruth’s 1919 "Curse of the Bambino" signed contract ($2.3 million), and a 1920 Ruth Yankees jersey ($4.5 million)

Lelands’ unprecedented depth of knowledge is matched by their highly technological approach that has enabled collectors from around the globe to access Lelands’ online auctions directly.


As Covid-19 erupted globally, Lelands recognized the growing appreciation for modern sports cards, not only as collector's items but also as alternative investment assets. 

The auction house wished to take full advantage of this paradigm shift and leverage over 4 decades' worth of invaluable bid and purchase data on the sports collectibles market


Using Artbrains proprietary AI engine, Lelands could automatically match each of their collectors’ individual interests with the right cards from their catalog.

Then, using Arbrain’s personalized marketing platform, the auction house sent their collectors sharply branded and tracked campaigns in a format proven to drive bids and grow sales.
