While I'm not a collector of exclusively Minor League stuff, I do have a few Birmingham Barons jerseys, bats, and baseballs. I agree, they seem to be harder to find, I only occasionally come across stuff. I think that its because the minor league teams re-use so much of their stuff longer as compared to the majors...I have no idea if this is the case, but I would assume so. One of my jerseys is a jersey from the 1990's and you can tell that it went through several seasons, as its very well-worn.
