Old lady got me a nice display case for all of my signed baseballs I'm pulling some of these out and was wondering if any of them have some value and what would be the best option to do with them.. i.e. save em and let them gain value or ditch them now.. some of the balls I have are A-rod, Chipper Jones, Harmon Killebrew, Paul Molitor, Rod Carew, 2 Michael Jordan baseballs I got when he was with the Birmingham Barons, and about 5 balls I cant for the life of me remember where I got them or who they are.. Can anyone shed some light and drop some knowledge.. Thanks
