2024 Topps Now Lou Gehrig Day Autographs is the most elusive set ever produced under the online banner — and it’s all for a good cause.

Featuring 30 cards, all are one-of-ones and available through a special MLB auction.

Every team is represented on the star-studded checklist. Highlights include Shohei Ohtani, Mike Trout and Julio Rodriguez. Within a day of bids opening, the Ohtani was up to more than $8,000.

In addition to being a one-of-a-kind and boasting on-card signatures, Gehrig is pictured in the background of each card. Backs explain the purpose of Lou Gehrig Day, which was honored across MLB on June 2.

Bidding continues through June 12 with proceeds going to the Sean M. Healey & AMG Center for ALS.
