The request is unfortunately vague, but I look to collect game used balls from all of the different "professional" baseball leagues. By my count, I'm at 176 so it's hard to list exact ones I need. If you've got a ball from a defunct league that you look to part with, please let me know.
Some specific targets I have in mind:
Maryland Fall League
Atlantic Coast League
American Athletic Conference
Empire State League
Heartland League
All-American Association
Thanks in advance.
