For about two decades, J. Ross Greene kept a deep, delightful secret. Outside of his circle of family and close friends and one or two people in the hobby, no one knew that in 1996 he spent the shocking sum of $46,000 on a baseball card ($103,000 in today’s money). “I didn’t have many friends who thought about baseball cards,” he told me from his home in the Atlanta area. “I’m sure they thought that ‘he’s got a lot of money or hasn’t got any sense.’”
