There are two ways to store BB's: 1) not going to display BB's - cool, dark low humidity area preferably a closet (no windows, no sunlight). If you are going to display - a cool, dry, low humidity room with UV protected glass and a dehumidifier in the room. I have several hundred autographed baseballs stored both ways with minimal issues. I would also recommend OMLB BB's, signing with ball point pen (vs. sharpie), not handle the BB's, all will extend the life of both the ball and the autograph. The moisture and oils from your skin will impact the BB over time. I have slight toning spots from the leather on some of the older BB's due to leather issues however overall they are in outstanding shape over four decades+.
