Heritage Auctions told TMZ Sports that the Hillerich & Bradsby bat, which Gehrig used at Columbia University through his earliest seasons with the New York Yankees, is the most "significant" in the collector's circuit.
"It was one of Gehrig's favorite bats and one he likely used over several seasons," Chris Ivy of Heritage said. "I believe that it's the most significant Gehrig bat in the hobby."
There have been no details revealed regarding the identity of the buyer.
Gehrig played for the Yankees from 1923-1939, dying two years later due to ALS.
