It seems like signed game-issue authentic jersey cost more. But I just kind of wonder why. I mean with a signed basketball, you get a much larger autograph. Jerseys tend to have much smaller autographs that are usually signed on one of the player's numbers, whereas an autograph on a basketball usually takes up an entire panel. Of course, unsigned jerseys usually cost more than unsigned basketballs as well.
I don't know james. I had a rugby legume signed ball popular team and Era with the greats on it sold it for 50 bucks if it were a jersey I would have cleaned up. Collectability I guess.
