Difficult to say, I will hazard a guess and say $300 for the less popular teams and maybe upwards of $400 for the more popular. This is just a blind guess mind you.
40 sets per team means 360 individual cards per team and an overall run of 5760. I don't think team sets will get broken up much because they will all come out of the packet with the same serial.
Black league leaders were two per case and /50 (800 total) and they hit a minimum of $300 now
