I don't know which trade involved the most Hall of Fame members...
I do know that this one had quite a few.
December 8, 1899.
Tom Messitt, Fred Clarke, Mike Kelley, Rube Waddell, Honus Wagner, Chief Zimmer, Deacon Phillippe, Claude Ritchey, Tommy Leach, Tacks Latimer, Bert Cunningham, and Jack Wadsworth, all to the Pirates for Jack Chesbro, George Fox, Art Madison, John O'Brien, and $25,000. That was a lot of money in the day.
5 members of the Hall, Chesbro, Clarke, Kelley, Waddell, and Wagner.
Here are a few cards, depicting a few of those guys. I like the T210 red border Old Mill card of Tom Messitt, who played 3 games in the majors, all in 1899 for Louisville of the National League.
