Chatted with my friend who I met many years ago from this board (turned out she live 1/2 mile from my house). Her ex was in professional baseball and her daughter was able to sell her memorabilia through Leland's auction house, which is apparently THE place for sports memorabilia, and they can authenticate as well. So I'll contact them first once I have gathered any other items. It would be the easiest way to go, and although none of this is worth a lot, the total might be an extra thousand or two, which would be nice.
