Notes
(1)	Dundee was awarded a bogus decision over Bernstein 12/17/23. Bernstein moved up in weight after draw with Sammy Mandell, who beat Dundee on 6/9/24.
(2)	Sullivan beat Dundee on 6/20, and solidified title claim by beating top contender Martin.
(3)	Title discontinued; Klick moved up in weight.
(4)	Sandy Saddler claimed title in 1949-50; only recognized by Ohio.
(5)	Stripped for failure to fight winner of eliminator bout. Remained idle until June 2012.
